Description

Technical Field

[0001] The utility model relates to the technical field of pulse bag dust removal, in particular to a low-emission pulse bag dust removal device. Background Art

[0002] The pulse bag dust collector is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the pulse bag dust collector, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. The gas containing finer dust is retained when passing through the filter material, so that the gas is purified.

[0003] For example, a pulse bag dust collector and a pulse bag dust collector device with application number CN201822071258.7 relate to the field of dust removal technology. The pulse bag dust collector includes a dust collection box, an ash hopper, an air pipe, a support pipe, a dust filter bag and a blowing pulse mechanism. The interior of the dust collection box is provided with a dust collection cavity, and the second end is open and connected to the dust collection cavity. The wall of the dust collection box is provided with a clean air outlet connected to the dust collection cavity, and the clean air outlet is close to the first end. The ash hopper is provided at the second end. The surrounding wall of the ash hopper is provided with a dust and air inlet connected to the dust collection cavity. The dust filter bag is located between the air pipe and the support pipe. One end of the dust filter bag is connected to the internal channel of the air pipe, and the other end of the dust filter bag is elastically connected to the support pipe. The blowing pulse mechanism is provided on the outer wall of the dust collection box and connected to the air pipe. However, the pulse bag dust removal device has poor adaptability, poor filtering effect on some gases containing special substances, and poor dust removal effect. In addition, the temperature inside the box is high, and the heat is difficult to reduce or discharge, which will have an adverse effect on the device.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a low-emission pulse bag dust removal device is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a low-emission pulse bag dust removal device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a low-emission pulse bag dust removal device, comprising a box body and an air inlet, the outer surface of the box body being fixedly connected to the air inlet, and a filtering mechanism being arranged inside the air inlet, the top of the box body being fixedly connected to a cooling device, and the bottom inner surface of the box body being fixedly connected to an ash hopper.

[0007] Preferably, the box body includes heat dissipation paint, and the inner wall of the heat dissipation paint is fixedly connected to the outer cylinder, and the inner wall of the outer cylinder is fixedly connected to the anti-corrosion layer.

[0008] Preferably, the filtering mechanism includes a mounting frame arranged on one side of the air inlet, and the internal thread of the mounting frame is connected with a bolt, one side of the mounting frame is fixedly connected to the filter element, and one end of the filter element is fixedly connected to the oil mist filter, and one side of the oil mist filter is provided with an odor adsorption layer.

[0009] Preferably, a blowing pipe is fixedly connected to the inner surface of the box, and one end of the blowing pipe is fixedly connected to a solenoid valve.

[0011] Preferably, the bottom of the blowing pipe is fixedly connected to a filter bag frame, and the outer surface of the box is fixedly connected to a clean air outlet.

[0012] Preferably, the outer surface of the box is fixedly connected to a pulse controller, and the bottom of the box is fixedly connected to a support frame, and the outer surface of the box is provided with an inspection door.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a filtering mechanism and a cooling device. When encountering dust-laden gas containing oil mist, condensed water and a high degree of dust adhesion, the filtering mechanism performs a primary filtration of the impurities inside the gas, thereby avoiding some inadaptability of the bag-type dust collector, which leads to bag sticking, incomplete dust cleaning, and shortening the service life of the bag-type dust collector, and reducing the dust removal efficiency. The cooling device maintains a suitable temperature inside the bag-type dust collector, ensuring the dust removal efficiency and uniformity of airflow distribution, avoiding deformation of the bag tube material in a high temperature environment, causing problems such as filter bag splitting and bag aging, and increasing the reliability and operational stability of the bag-type dust collector;

[0015] 2. The utility model is used to purify corrosive gases through the setting of the internal coating and pulse valve of the box. The anti-corrosion layer protects the inner wall of the box to prevent the inner wall of the box from being corroded. The heat dissipation coating prevents the internal temperature of the box from being too high. The pulse valve is set on the upper part of the compressed air storage bag to prevent moisture, oil and other substances in the air bag from entering the interior of the filter bag box.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 2 As shown, a low-emission pulse bag dust removal device includes a box body 1 and an air inlet 2. The outer surface of the box body 1 is fixedly connected to the air inlet 2, and a filtering mechanism 3 is arranged inside the air inlet 2. The top of the box body 1 is fixedly connected to a cooling device 4, and the bottom inner surface of the box body 1 is fixedly connected to an ash hopper 5. The filtering mechanism 3 can be disassembled. When a large amount of oil mist and dust adheres to the outer surface of the filtering mechanism 3, it can be disassembled and replaced to improve the adsorption effect. The cooling device 4 includes components such as a condenser coil and a fan to keep the inside of the box body 1 at a suitable temperature.

[0023] like Figure 3 As shown, the box body 1 includes a heat dissipation coating 101, and the inner wall of the heat dissipation coating 101 is fixedly connected to an outer cylinder 102, and the inner wall of the outer cylinder 102 is fixedly connected to an anti-corrosion layer 103. The heat dissipation coating 101 transfers the heat on the surface of the box body 1 to the air, thereby reducing the temperature of the box body 1. The anti-corrosion layer 103 prevents corrosive gases from directly contacting the inner wall of the box body 1, thereby protecting the box body 1.

[0024] Furthermore, the filtering mechanism 3 includes a mounting frame 301 arranged on one side of the air inlet 2, and the internal thread of the mounting frame 301 is connected with a bolt 302, one side of the mounting frame 301 is fixedly connected to the filter element 303, and one end of the filter element 303 is fixedly connected to the oil mist filter 304, and an odor adsorption layer 305 is provided on one side of the oil mist filter 304. The bolt 302 connects the mounting frame 301 to the air inlet 2 for easy removal and cleaning. The material of the odor adsorption layer 305 is activated carbon adsorption cotton. When odor or volatile gases pass through the pores of the activated carbon, the impurities will be adsorbed on the internal surface by the capillaries of the activated carbon, reducing the pollution of subsequent exhaust gas to the atmosphere.

[0025] Furthermore, a blowing pipe 6 is fixedly connected to the inner surface of the box body 1, and a solenoid valve 7 is fixedly connected to one end of the blowing pipe 6. A pulse valve 8 is provided at the bottom end of the solenoid valve 7, and a compressed air storage bag 9 is fixedly connected to the bottom of the pulse valve 8. A plurality of groups of blowing holes are provided on the outer surface of the blowing pipe 6. The solenoid valve 7 and the pulse valve 8 are components of the compressed air storage bag 9, which can optimize the cleaning performance and reduce energy consumption.

[0026] Furthermore, a filter bag frame 10 is fixedly connected to the bottom of the blowing pipe 6, and a clean gas outlet 11 is fixedly connected to the surface of the box body 1, a pulse controller 12 is fixedly connected to the outer surface of the box body 1, and a support frame 13 is fixedly connected to the bottom of the box body 1, and an inspection door 14 is provided on the outer surface of the box body 1. The pulse controller 12 can adjust the blowing cycle and blowing time. The filter bag frame 10 consists of a filter bag and a frame, and the purified gas is discharged through the clean gas outlet 11.

[0027] Working principle: When using the low-emission pulse bag dust collector, the gas containing impurities is first transported through the air inlet 2 to the interior of the box 1 composed of heat dissipation coating 101, outer cylinder 102 and anti-corrosion layer 103. The filter mechanism 3 inside the air inlet 2 performs initial filtration on the gas. When the surface of the filter element 303, oil mist filter 304 and odor adsorption layer 305 adsorbs too many impurities, the components can be removed by bolt 302 for cleaning. Then the air enters the filter bag of each filter bag frame 10 through the pulse valve 8 and the blowing port on the blowing pipe 6 from the compressed air storage bag 9. The gas is filtered and discharged through the clean air outlet 11. Finally, due to the acceleration generated by the expansion and the reverse airflow, the dust attached to the outer surface of the filter bag of the filter bag frame 10 falls off the filter bag and falls into the ash hopper 5 for discharge. This is the working principle of the low-emission pulse bag dust collector.
