[0002] Existing flue gas treatment generally adopts bag dust collector, but the bags of the existing bag dust collector are relatively short and the chamber is single. When in use, the shorter bags have low dust removal efficiency, and after the shorter bags are recoiled, some dust will adhere to the bags again, affecting the service life of the bags. Therefore, a harmless smoke exhaust and dust removal system is proposed. Utility Model Content

[0006] Preferably, the number of the quenching tower and the number of the desulfurization tower are both two and are symmetrically distributed on both sides of the dust collector.

[0007] Preferably, there are two fans, and both fans can blow air in the opposite direction.

[0008] Preferably, the length of the dust collector is greater than the sum of the lengths of the quench tower and the desulfurization tower, and the dust collector is composed of a dust bag, an ash hopper, an upper box body, a middle box body, and a lower box body.

[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0016] A harmless smoke exhaust and dust removal system provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0017] Example:

[0018] Combination Figure 1 As shown, the utility model provides a harmless smoke exhaust and dust removal system, including a main frame 110, on which a fan 120 is installed, the number of the fans 120 is two, both fans 120 can blow air in the opposite direction, the air inlet end of the fan 120 is connected to a centralized exhaust duct 130, the other end of the centralized exhaust duct 130 is connected to a dust collector 140, the bottom of the dust collector 140 is connected to a quenching tower 150 and a desulfurization tower 160, the quenching tower 150 The number of the desulfurization tower 160 is two symmetrically distributed on both sides of the dust collector 140. The length of the dust collector 140 is greater than the sum of the lengths of the quenching tower 150 and the desulfurization tower 160, and the dust collector 140 is composed of dust bags, an ash hopper, an upper box body, a middle box body, and a lower box body. The quenching tower 150 and the desulfurization tower 160 are through-connected, and the desulfurization tower 160 is connected to the ash hopper, and the air inlet ends of the quenching tower 150 and the desulfurization tower 160 are connected to the air inlet pipe 170.

[0019] Specifically, the dust collector 140 is divided into three chambers, and each chamber is individually connected to the centralized exhaust duct 130, so that when cleaning, the chamber that needs to be cleaned is opened, thereby achieving the purpose of cleaning in batches, avoiding the dust from adhering to the dust bags again, and improving the practicality of the device. In addition, during recoil, the dust on the dust bags will be blown into the ash hopper, further realizing the separation of dust and chambers, improving the reliability of the device, and extending the service life of the dust bags.

[0020] The working principle and use process of the utility model are as follows: first, the dust-containing gas enters the quenching tower 150 through the air inlet pipe 170 for rapid cooling, then enters the desulfurization tower 160 for desulfurization, and then enters the dust collector 140. Large dust particles will fall to the bottom of the ash hopper, and fine dust will be filtered by the dust bag. Clean air is discharged to the outside through the fan 120;

[0021] In addition, when backflushing is required, the fan 120 is blown in the reverse direction, so that the dust bag is shaken to shake off the particles adhering to it, and the particles fall into the ash hopper for centralized treatment, and finally backflushing is performed at a fixed time.

[0022] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
