Detailed Explanation of Environmental Protection of Gas Pollutants for Regenerative Building Materials-WJW Aluminum Supplier Aluminum

RecycleDaluminium is an important source of building -type materials or construction metal metal by waste construction materials or waste construction materials or waste materials containing construction materials. It is an important source of metal construction materials. Regenerative construction materials are presented in the situation of construction materials. Regenerative construction materials must be tested strictly before use. National non -ferrous metals may be tested for regenerative construction materials, and corresponding tests are issued.

1. The source of the waste gas dyeing of the regenerative construction material

my country's waste construction of the regeneration of the construction of profiles is important to melt the fire method, which generates the process of exhaust gas and the possible impact on the environment is the melting process. In the melting process, the important fuels are coal, coke, heavy oil, diesel, gas, natural gas, etc. After the fuel is incinerated, the exhaust gas generated in the exhaust gas contains a large amount of smoke and sulfur, carbon, phosphorus and nitrogen oxides and other gases. ; After the furnace (waste construction) is heated, the oil pollution and combustibles of the waste itself will be burned, and a large amount of oxides containing sulfur, carbon and nitrogen will be produced; The recovery rate and ensure the quality of the construction material, to add a certain number of shrouded agents, refining agents and gas removal agents. These additives react with the various impurities in the built -in material melt. Smoke and dust contain various metal oxides and non -metal oxides, and may also contain harmful substances, which may be contaminated with the environment.

2. Classification and ingredients of waste -building flue gas

1. Classification of exhaust gas in the waste construction industry

According to the specification of the environmental protection part, the waste gas generated by the industry may be divided into two categories: granular exhaust gas and gas -containing contamination. Because the raw materials in the regenerative construction material industry are complicated, there are two exhaust gas in the production process at the same time, with both particulate material exhaust gas and gas -containing stained exhaust gas. Therefore, while treating the exhaust gas The impact of harmful gases on the environment.

2. Important ingredients of smoke

Because the source channels for the raw materials of the waste construction industry are different, the variety of waste materials, the different levels of the staining, the different fuels, the different agent components, and the melting techniques adopted. There may be the following types of interpretation:

(1) Grame -shaped waste is the important thing is the metal oxide and non -metal oxides generated in the melting process, such as: M

G, z

N, C

A, A

L, F

E, n

A, m

The oxide and chloride of G and K, as well as a large amount of carbon grain, etc., the above forms the dust we often talk about. Architectural materials (such as plastic, aluminum, glass fiber, etc.) with a certain strength and toughness (such as plastic, aluminum, glass fiber, etc.) have certain geometric shapes made of rolling, extrusion, casting and other processes. The process of production of profiles is used to squeeze the profiles, which are divided into two categories: hollow profiles and solid materials.

(2) Important ingredients of gas staining infection exhaust gas. The regenerative construction material industry may have the following gas dipping infected from contamination, C

O, CO2, NO

X, SO2, HC

L, H

F, hydrocarbons and volatile metal oxides or volatile metals may also have chlorine gas, etc. Of course, not all ingredients are harmful, but most of them will have a great impact on the environment. Some may be possible It will endanger the life insurance of workers.

Third, the governance of smoke and dust

The goal of smoke and dust governance is to collect the dust in the flue gas to a large extent, transform the harmful gases into harmless and firm substances, and achieve national emissions standards. For the governance of the environment, we must first control from the source. For renewable construction materials, it is necessary to strengthen the preparatory processing and classification of waste materials, try to use various waste materials to comprehensively use The increase agent; the third is to improve the melting skills to reduce the amount of waste. The commonly used smoke and dust treatment skills are as follows:

1. Dust room

The dust collection room is a simpler method in the dust collection equipment. The principle is that when the speed of the fluid suddenly slows down, the particles in it are sinking down due to its own gravity. The flue gas generated by the recycled construction material flows at a certain speed in the flue. When the space of the flue suddenly increases, the speed of the airflow suddenly slows down. Because the speed of the particle movement falls, the particles are deposited under their own gravity. Essence There are many types of dust rooms.

The simpler way is to make bricks. If there are some baffles in the dust collection room, the consequences of the dust collection may be improved, but in general, the dust collection of the dust room is not good.

2. Whirlwind dust collector

The whirlwind dust collector is a relatively practical dust collection setting. The investment is low and the consequences are better. Many companies are adopted in many companies. The whirlwind dust collector can also be called a centrifugal dust collector.

When the gas enters the dust collector in the direction of the tangent line, the airflow will rotate high -speed in a certain direction in a certain direction. On the wall, because of its own gravity landing into the dust collection room, the consequences of the dust collection. The consequences of the whirlwind dust collector are obvious, and it is used in many enterprises that produce dust.

3. Spray dust collector

The principle is to capture the particles in the gas during the landing process of a solution. After the particles are moist, they will also adsorb the remaining particles. Compared with their own gravity, it is collected to the dust room.

Set a number of nozzles within a cylinder to hold the holes, flow, pressure and angle of the nozzle, make the sprayed liquid fog -like, the gas picks up from the lower end, the particles are captured, and the spray dust collector is a simple way. The easy -to -use dust collection settings are generally used.

4. Pulfa

Poista is also a commonly used dust collector. The consequences are higher than the above dust collectors, but the investment is large and the operation is difficult. The principle is to set up a partition in the next position within a cylinder. There are countless small holes on the partition. When the deformity is running, there is a solution layer on the partition. The liquid layer, dust is captured by liquid, and the clean gas is eliminated by the upper end of the liquid. When the pressure of the gas is the pressure generated by the liquid on the partition, the two phases of the gas liquid are static. When the pressure of the gas is greater than the water pressure, the air flow is smooth than the liquid, but the pressure of the gas and the height of the water layer are designed by calculation by calculation. The pressure of the gas is too large to reach the consequences of dust collection. In actual production, the water surface is boiling.

5. Bag Cooking Cleaner

The important way to collect dust is the dust collector of the cloth bag. The principle is to make the dust -containing gas through the filter bag to achieve the consequences of dust collection. There are two commonly used: commonly used:

(1) Foreign type: There are multiple bags in the dust collector. The name of the bag house is filter cloth. During production, the exhaust gas enters the dust collector, the house is negative pressure, and the dust -containing gas enters the dust collector. In the name of filter cloth, the gas after the contamination is eliminated from the bag. After running a certain period of time, the dust on the filter cloth is deposited, the breathable function landing affects the consequences of dust collection and exhaustion. Therefore, it is necessary to remove the dust in time, to start the tightening air, carry out reverse blowing air, dust fall off, and the dust falls off. Enter the dust room.

(2) Internal cloth bag dust collector: It is reasonable to the external system, but the dust -containing gas enters the bag in the bag. The outside of the bag is negative pressure. After the vibration, the dust took the initiative to fall into the dust room, reaching the consequences of dust removal.

The cost of collecting dust in cloth bags is absolutely high, but a dust collector often adopts. Architectural materials (such as plastic, aluminum, glass fiber, etc.) with a certain strength and toughness (such as plastic, aluminum, glass fiber, etc.) have certain geometric shapes made of rolling, extrusion, casting and other processes. The process of production of profiles is used to squeeze the profiles, which are divided into two categories: hollow profiles and solid materials. When choosing a bag to collect the dust collector, be sure to pay attention to the temperature of the cloth bag, which is below 250 degrees. In addition to the above equipment, there are relatively progressive dust collection equipment such as electricity, but because of the high cost, there are currently many companies in the regenerative construction material industry.

Fourth, the governance techniques of gas dipping infection exhaust gas

For the ingredients of gas stains, the ingredients have been introduced above. Regarding the control of such exhaust gas, the important cause of the current enterprise is basically not governing. The important cause is that there are many varieties of harmful gases produced by the renewable construction material industry, and it is difficult to distinguish and deal with it. However, we may see that these gases are still in common. This is that the substances in the gas stained in the exhaust gas are mostly acidic, which is convenient for the treatment of exhaust gas. In some cases, only weak alkaline substances can be effectively governed. Some of them are added to NA2CO3 for mid -heels, which are discharged compared to post -standard emissions.

In the wet method mentioned above, such as spray tower and poker tower, some of them are added with water. If alkaline substances are added to the water, the harmful substances in the exhaust gas may be treated while collecting the dust. Architectural materials (such as plastic, aluminum, glass fiber, etc.) with a certain strength and toughness (such as plastic, aluminum, glass fiber, etc.) have certain geometric shapes made of rolling, extrusion, casting and other processes. The process of production of profiles is used to squeeze the profiles, which are divided into two categories: hollow profiles and solid materials.

The above introduces how many commonly used environmental protection equipment, hoping to refer to enterprises when building environmental protection equipment. At the same time, enterprises must consider the characteristics of renewable construction materials to produce smoke -not continuously generate exhaust gas, but to generate intermittent exhaust gas. The above -mentioned cloth bag dust collector, whirlwind dust collector, spray tower, etc. are more suitable for the characteristics of the industry.
