[0035] The same reference numerals in the drawings all refer to the same components. EMBODIMENT

[0036] As Figures 1-4 shown, the utility model provides a dust collecting equipment for flue gas treatment, including particulate matter treatment equipment main body 1 and dust collecting equipment main body 2, the inside of particulate matter treatment equipment main body 1 is provided with a plurality of second baffle 20, and the top of particulate matter treatment equipment main body 1 is provided with inlet pipe 3 and outlet pipe 4, and the side of dust collecting equipment main body 2 is provided with air inlet pipe 5, and outlet pipe 4 and air inlet pipe 5 are fixedly connected through connecting pipe 19, and the bottom of dust collecting equipment main body 2 is provided with dust discharge hopper 6, and the other side of dust collecting equipment main body 2 is provided with exhaust pipe 7, and the inside of dust collecting equipment main body 2 is provided with dust removal assembly 8, and dust removal assembly 8 includes:

[0037] Partition 9 has through hole 901, and partition 9 is arranged at the upper side of the inner surface of dust collecting equipment main body 2, and a plurality of through holes 901 are arranged on the side of partition 9;

[0038] Heat preservation layer 10 is arranged on the inner surface of dust collecting equipment main body 2;

[0039] The gap between partition 9 and the top surface of the inner surface of dust collecting equipment main body 2 forms flue 17, and the gap between partition 9 and heat preservation layer 10 forms clean gas chamber 18;

[0040] Fixing frame 11 has dust removal cloth bag 111, and fixing frame 11 is arranged on the inner surface of dust collecting equipment main body 2, and dust removal cloth bag 111 is arranged on the bottom of fixing frame 11;

[0041] First baffle 12 is arranged at the lower side of the inner surface of dust collecting equipment main body 2.

[0042] The fixing frame 11 is located on the bottom surface of the insulation layer 10, and the first guide plate 12 is located slightly above the air intake pipe 5.

[0043] A number of lifting valves 13 are installed on the top surface of the main body 2 of the dust collection equipment;

[0044] Stabilizing air bag 14 is located on the rear side of the main body 2 of the dust collection equipment;

[0045] Pulse valve 15, several pulse valves 15 are disposed on the top surface of the stabilizing air tank 14;

[0046] Pulse tube 16, several pulse tubes 16 are arranged on the bottom surface of the stabilizing air bag 14;

[0047] The pulse tube 16 is inserted into the clean air chamber 18 inside the dust collection device body 2.

[0048] Specifically, such as Figures 1-4 As shown, the partition 9 is used for layering, dividing the space into two sets of spaces: the flue 17 and the clean air chamber 18. The through hole 901 in the partition 9 is used to conduct gas from the clean air chamber 18 to the flue 17, and then discharge it through the exhaust pipe 7 on one side of the flue 17. The insulation layer 10 effectively isolates the clean air chamber 18, the flue 17, and the dust collector filter bags 111 inside the dust collector, reducing heat loss due to temperature differences and ensuring that the internal temperature of the dust collector is maintained within the optimal operating range. Simultaneously, the presence of the insulation layer 10 stabilizes the internal temperature of the dust collector, preventing filter bag aging or malfunction due to temperature fluctuations, thereby extending the service life of the filter bags. The first guide plate 12 is used to prevent dust from falling back to the inlet pipe 5 when the dust collector bags 111 fall, and also guides the dust to the bottom dust discharge funnel 6. The lifting valve 13 is used for... The control is located inside the valve plate. When the pulse tube 6 injects compressed air into the interior, the lifting valve 13 can move the valve plate downward to fit against the partition 9, thereby sealing the through hole 901 on the partition 9. This prevents dust from being blown down to the flue 17 due to the action of the compressed air when the pulse tube 16 injects compressed air into the dust collector bag 111. The dust and airflow will be lifted to the dust collector bag 111 by the external fan, filtered by the dust collector bag 111, and then enter the clean air chamber 18. It will then be discharged from the clean air chamber 18 through the exhaust pipe 7. The stabilizing air tank 14 is used to store compressed air, and the pulse valve 15 is used to control the airflow. Compressed air is injected into the interior through the pulse tube 16. The pulse tube 16 is used to transfer the compressed air into the dust collector bag 111, thereby causing the dust collector bag 111 to shake and shake the dust down to the dust discharge funnel 6 at the bottom.

[0049] The partition 9 and the fixing frame 11 are arranged in parallel, and the flue 17 and the clean air chamber 18 have the same size.

[0050] Specifically, such asFigures 1-4 As shown, the parallel arrangement of the partition plate 9 and the fixing frame 11 helps to guide the airflow to be evenly distributed inside, avoiding uneven dust removal efficiency caused by excessive or insufficient local airflow.

[0051] The fixing frame 11 is welded on the inside of the dust collection equipment body 2, and the fixing frame 11 is attached to the thermal insulation layer 10. The fixing frame 11 is a flower plate, and the thermal insulation layer 10 is made of rock wool material.

[0052] Specifically, as shown in the figure, Figures 1-4 The fixing frame 11 is welded on the inside of the equipment body 2, providing a stable support structure and enhancing the stability of the entire dust collection equipment. Rock wool, as a high-quality thermal insulation material, has a low thermal conductivity and good thermal insulation performance, which can effectively reduce heat loss and improve the energy efficiency of the dust collection equipment.

[0053] The pulse pipe 16 has an upper end 161 and a lower end 162. The upper end 161 and the lower end 162 are arranged in an L shape, and the lower end 162 is placed in the flue. The lower end 162 is aligned with the dust removal cloth bag 111, and the pulse pipe 16 is fixedly connected with the dust collection equipment body 2.

[0054] Specifically, as shown in the figure, Figures 1-4 The arrangement of the lower end 162 aligned with the dust removal cloth bag 111 ensures that compressed air can be directly and accurately sprayed onto the cloth bag, effectively removing dust on the surface of the cloth bag.

[0055] The dust removal cloth bag 111 is fixedly connected with the fixing frame 11. The dust removal cloth bag 111 is a bag filter element made of fiber woven material. It can also use stainless steel mesh, which is a martensitic heat-resistant steel that can resist high temperatures of 500°C. Steel material has good resistance to general chemical corrosion and can maintain stable filtration performance in corrosive gas environment.

[0056] The first flow guide plate 12 is in an L shape, and the first flow guide plate 12 is welded on the inside of the dust collection equipment body 2.

[0057] Specifically, as shown in the figure, Figures 1-4 The L-shaped arrangement of the first flow guide plate 12 can prevent dust from depositing on the air inlet pipe 5.

[0058] The exhaust pipe 7 is a high-temperature dust exhaust pipe 7, which is inserted into the inside of the flue 17. The exhaust pipe 7 is vertically arranged with the dust collection equipment body 2.

[0059] Working principle: when the dust bag 111 needs to be cleaned, the lift valve 13 is opened to seal the through hole 901 on the partition plate 9, and then the pulse valve 15 is opened, compressed air is sprayed to the dust bag 111 through the pulse tube 16, the inside of the dust bag 111 is instantaneously pressurized and expanded, the dust bag 111 is fully shaken and forms a blowback airflow from inside to outside, the dust attached to the outer surface of the dust bag 111 is removed, and the dust of the dust bag 111 is deposited in the dust discharge hopper 6, so that the dust removal purpose is achieved.

[0060] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
