Boiler dust collector has played a very good role in environmental protection

The structural characteristics of the boiler dust collector is that its structure is relatively simple, and the quotation that can be consumed is relatively low. But when working, the power of dust removal is relatively high. We can apply this product to some high-temperature environment and environment prone to incineration. The boiler dust collector can also properly remove harmful substances near the gas at the time of dust removal. However, it also has its own shortcomings, such as its relatively high water consumption. We should measure these deficiencies before purchasing and using them.

Some of the devices include biological dust suppressors. This is something that specifically occurs for dust, and the advantages compared to other equipment are still very significant. It can control the movement of dust around the surrounding environment in the process of being applied, so that the dust emission can be controlled and controlled. To a certain extent, it can greatly increase the power of dust removal, and it can also make the energy consumption it pays Decline.

The working hours of this part can make the presented dust become fine material, and then become the material of the product. This is also directly related to the bio-nano-membrane technology it uses. Under this connection, the output value can be increased inevitably. The existence of the nano-membrane can make the materials of the product not cause any pollution to the environment, and it also meets our environmental protection and energy saving policy.

Working principle of bag filter

(1) Filter type dust collector refers to the equipment that realizes gas-solid separation when the dust particles in the air flow are intercepted and collected by the filter layer when the dust-containing flue gas passes through the filter layer.

(2) The filter type dust removal device includes a bag type dust collector and a particle layer dust collector. The former usually uses a filter bag made of organic fiber or inorganic fiber fabric as the filter layer, while the latter filter layer mostly uses particles of different particle sizes, such as Quartz sand, river sand, ceramsite, slag, etc. With the powder repeatedly attached to the outer surface of the filter bag, the powder layer continues to thicken, and the resistance value of the bag filter also increases; the pulse valve diaphragm issues a command, the pulse valve opens when submerged from left to right, and the pressure in the high-pressure air bag is compressed. The air is vented. If there is no dust or it is small enough, mechanical dust removal will stop working.

(3) The gas purification method of the low-pressure pulse bag type dust collector is an external filter type. Dust-containing gas enters the filter room of each unit through the diversion tube. Since the bottom of the filter bag is designed to have a sufficient and reasonable airflow from the upper opening of the air inlet, Through proper diversion and natural flow direction distribution, the air in the entire filtering room is evenly distributed. The particulate dust in the dust-containing gas is directly separated into the ash hopper after being separated by natural sedimentation. The remaining dust is guided by the diversion system and enters the middle box with the airflow. The body filtration area is adsorbed on the outer surface of the filter bag. The filtered clean gas passes through the filter bag and is discharged through the upper box and the exhaust pipe.

(4) The filter bag uses compressed air to spray and clean the ash. The ash cleaning mechanism is composed of an air bag, a spray pipe and an electromagnetic pulse control valve. A spray pipe is installed at the top of each row of filter bag outlets in the filter room. The lower side of the spray pipe is directly opposite the center of the filter bag. A spray valve is provided on each spray pipe and communicates with the compressed air bag. During ash cleaning, the solenoid valve opens the pulse valve, and the compressed air is sprayed by the ash cleaning control device (differential pressure or timing, manual control) to open the electromagnetic pulse spray according to the set program. The compressed gas passes through each pulse in a short time and in sequence. The valve induces several times the amount of air injected into the filter bag through the nozzle on the blowing pipe, forming an air wave, which causes the filter bag to expand sharply and impact vibration from the bag mouth to the bottom, resulting in a strong dust removal effect and shaking off the filter. Dust on the bag. Bag dust collector for dust removal by vibration and reverse airflow.

With the rapid development of our economy, our ecological environment has also been severely damaged. The traditional boiler has severe pressure and impact on the environment because the fuel is a mineral resource and there is no structure for flue gas treatment. Moreover, its performance is also relatively poor, so it is gradually eliminated by the market. With the continuous improvement of people's awareness of environmental protection, many new boilers continue to appear, and boiler dust collectors are also cited on the boiler, which has played a very good effect in environmental protection.
