An atmospheric treatment device for flue gas purification

Abstract

An air purification device for flue gas includes a first housing connected to a filter screen via bolts. The first housing contains a striking mechanism. When the roller in contact with the crossbar disengages from the crossbar, the spring force causes the crossbar to move rapidly to the left, causing the rubber pad at the left end of the crossbar to strike the filter screen. This dislodging of large particles clogging the filter screen improves subsequent performance and reduces the frequency of filter cleaning. Through the cooperation of the base and the discharge mechanism, the output end of a multi-stage hydraulic cylinder extends, driving a slider to slide along a slot. This, in turn, causes the crossbar and movable rod to swing to the upper right of their connection point with the base, tilting the second housing downwards to the right. This prevents excessive residual spray liquid inside the second housing, reducing corrosion of the inner wall and lowering maintenance costs.

Description

Technical Field

[0001] This utility model relates to the field of air pollution control equipment technology, and in particular to an air pollution control device for flue gas purification. Background Technology

[0002] The atmospheric environment refers to the physical, chemical, and biological characteristics of the air on which living organisms depend for survival. Harmful gases such as ammonia, sulfur dioxide, carbon monoxide, nitrogen oxides, and fluorides emitted by human life or industrial and agricultural production can alter the original composition of the air and cause pollution. Therefore, it is necessary to use flue gas purification equipment to treat harmful gases in industry and daily life.

[0003] For example, an air pollution control purification tower with announcement number "CN212941940U" uses a combination of a pretreatment box, inlet pipe, filter bags, M-shaped pipe, connecting pipe, fan, connecting pipe, annular plate, annular cavity, and exhaust port to pre-treat the flue gas from spray purification and ensure that the sprayed flue gas enters the interior of the purification tower body evenly, increasing the spraying effect. Furthermore, the combination of handles, connecting plates, through holes, rectangular frames, sealing strips, and sealing grooves facilitates filter bag replacement, increasing cleaning convenience. However, with prolonged use of filter bags, this air pollution control purification tower is prone to dust accumulation, leading to filter bag blockage and affecting subsequent use. Additionally, when it is necessary to discharge the spray liquid from the bottom of the purification tower, the bottom is relatively flat, and some spray liquid cannot be discharged. The spray liquid usually contains acidic or alkaline substances, which can easily corrode the casing, increasing maintenance costs. Summary of the Invention

[0004] This invention aims to solve the problems existing in the prior art by providing an atmospheric treatment device for flue gas purification, which reduces dust on the filter screen and improves the subsequent use effect. It can also completely discharge the spray liquid inside the second chamber, thereby reducing maintenance costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This atmospheric treatment equipment for flue gas purification includes a base, a first box and a second box. The first box and the second box are arranged sequentially from left to right on the top of the base. A material discharge mechanism is provided on the top of the base. The bottom of both the first box and the second box are fixedly connected to a horizontal plate. A fan is fixedly connected to the left side of the second box. The left side of the fan is fixedly connected to the first box through an exhaust pipe. The top of the fan is fixedly connected to the second box through an exhaust pipe. A filter screen is bolted to the top of the first box. A knocking mechanism is provided inside the first box.

[0006] To further improve the design, the lower left side of the first housing is connected to the door with screws, a flange is fixedly connected to the upper left side of the first housing, and a spray pipe is fixedly connected to the upper part of the second housing.

[0007] Further improvements include a servo motor, with a rotating block fixedly connected to the output shaft end of the servo motor. Rollers are mounted on the ends of the rotating blocks, with the outer walls of the rollers slidably connected to a crossbar. The inner wall of the crossbar is slidably connected to a limiting rod. The right side of the limiting rod is fixedly connected to a first housing. The outer wall of the crossbar is slidably connected to a fixing block, and the outer wall of the fixing block is fixedly connected to the first housing. A spring is provided on the right side of the fixing block, with both ends of the spring fixedly connected to the crossbar and the fixing block, respectively. A rubber block is fixedly connected to the end of the crossbar, and the rubber block at the end of the crossbar abuts against the filter screen.

[0008] Further improvements include a fixed connection between the end of the servo motor and the first housing, and a rotatable connection between the output shaft of the servo motor and the first housing via a sealed bearing.

[0009] Further improvements include a multi-stage hydraulic cylinder. The output end of the multi-stage hydraulic cylinder is movably connected to a slider via a pin. The slider is slidably connected to a horizontal plate via a slot. The slot is machined at the bottom of the horizontal plate. Multiple movable rods are provided on the right side of the multi-stage hydraulic cylinder. The upper ends of the movable rods are all fixedly connected to the horizontal plate, and the lower ends of the movable rods are movably connected to the base via pins. A support plate is provided on the left side of the multi-stage hydraulic cylinder. The support plate is slidably connected to the horizontal plate and the base via grooves. The grooves are machined on the left side of the base and the horizontal plate, respectively.

[0010] Further improvements include a multi-stage hydraulic cylinder with its end fixedly connected to the base, and an exhaust pipe and a drain pipe fixedly connected sequentially from top to bottom on the right side of the second housing.

[0011] The beneficial effects of this utility model are as follows: Through the cooperation of the second housing and the striking mechanism, the output shaft of the servo motor rotates, driving the rotating block to rotate clockwise, thereby driving the roller to move. The movement of the roller causes the crossbar to move to the right along the outer wall of the limit rod, while stretching the spring. When the roller in contact with the crossbar disengages from the crossbar, the elastic force of the spring causes the crossbar to move quickly to the left, causing the rubber pad at the left end of the crossbar to strike the filter screen, thereby shaking away large particles of impurities clogging the filter screen. To a certain extent, this can improve the subsequent use effect and reduce the number of times the operator cleans the filter screen.

[0012] With the cooperation of the base and the discharge mechanism, the output end of the multi-stage hydraulic cylinder extends and drives the slider to slide along the slot. This, in turn, drives the horizontal plate and the movable rod to swing to the upper right of the connection point with the base, causing the second box to tilt to the lower right. This prevents excessive spray liquid from remaining inside the second box, reducing the corrosion of the inner wall of the second box by the spray liquid and thus lowering maintenance costs.

[0015] The present invention will be further described below with reference to the accompanying drawings: See attached document Figure 1-5 In this embodiment, an atmospheric treatment device for flue gas purification includes a base 1, a first housing 2, and a second housing 10. The first housing 2 and the second housing 10 are arranged sequentially from left to right on the top of the base 1. A discharge mechanism 9 is provided on the top of the base 1. The bottoms of the first housing 2 and the second housing 10 are both fixedly connected to a horizontal plate 15. A fan 13 is fixedly connected to the left side of the second housing 10. The model of the fan 13 and the multi-stage hydraulic cylinder 901 can be selected according to actual needs to meet the working requirements. The left side of the fan 13 is fixedly connected to the first housing 2 through an exhaust pipe 7, and the top of the fan 13 is fixedly connected to the second housing 10 through an exhaust pipe 8. The top of the first housing 2 is connected to a filter screen 5 by bolts. The mesh size of the filter screen 5 can be selected according to actual needs to meet the working requirements. A striking mechanism 6 is provided inside the first housing 2.

[0016] Sealing gaskets are provided at the lower left side of the first housing 2 and at the connection between the door 3, the frame of the door 3 and the filter screen 5, and the maintenance door installed on the front side of the first housing 2 and the first housing 2. These gaskets can be used to seal the connection. The maintenance door facilitates the maintenance of the striking mechanism 6, which is connected by screws. A flange 4 is fixedly connected to the upper left side of the first housing 2. A spray pipe 11 is fixedly connected to the upper part of the second housing 10. The end of the servo motor 601 is fixedly connected to the first housing 2. The output shaft of the servo motor 601 is rotatably connected to the first housing 2 through a sealed bearing. The end of the multi-stage hydraulic cylinder 901 is fixedly connected to the base 1. An exhaust pipe 12 and a drain pipe 14 are fixedly connected from top to bottom on the right side of the second housing 10.

[0017] The striking mechanism 6 includes a servo motor 601. A rotating block 602 is fixedly connected to the end of the output shaft of the servo motor 601. Rollers 603 are mounted on the ends of the rotating blocks 602. The outer walls of the rollers 603 are slidably connected to a crossbar 604. The inner wall of the crossbar 604 is slidably connected to a limiting rod 607. The right side of the limiting rod 607 is fixedly connected to the first housing 2. The outer wall of the crossbar 604 is slidably connected to a fixing block 606. The outer wall of the fixing block 606 is fixedly connected to the first housing 2. A spring 605 is provided on the right side of the fixing block 606. The spring force coefficient of the spring 605 is selected according to actual needs to meet the operational requirements. Two springs 605... The ends are fixedly connected to the crossbar 604 and the fixing block 606 respectively. A rubber block is fixedly connected to the end of the crossbar 604. The rubber block at the end of the crossbar 604 abuts against the filter screen 5. The output shaft of the servo motor 601 rotates, driving the rotating block 602 to rotate clockwise, thereby driving the roller 603 to move. The movement of the roller 603 drives the crossbar 604 to move to the right along the outer wall of the limiting rod 607, while stretching the spring 605. When the roller 603 in contact with the crossbar 604 disengages from the crossbar 604, the elastic force of the spring 605 causes the crossbar 604 to move quickly to the left, causing the rubber pad at the left end of the crossbar 604 to strike the filter screen 5.

[0018] The discharge mechanism 9 includes a multi-stage hydraulic cylinder 901. The output end of the multi-stage hydraulic cylinder 901 is movably connected to a slider 902 via a pin. The slider 902 is slidably connected to the horizontal plate 15 via a slot 903. The slot 903 is machined at the bottom of the horizontal plate 15. Multiple movable rods 904 are provided on the right side of the multi-stage hydraulic cylinder 901. The upper ends of the movable rods 904 are all fixedly connected to the horizontal plate 15, and the lower ends of the movable rods 904 are movably connected to the base 1 via pins. A support plate 905 is provided on the left side of the multi-stage hydraulic cylinder 901. The support plate 905 is slidably connected to the horizontal plate 15 and the base 1 via grooves 906. The grooves 906 are machined on the left side of the base 1 and the horizontal plate 15, respectively. The movement of the output end of the multi-stage hydraulic cylinder 901 drives the slider 902 to slide along the slot 903, which in turn drives the horizontal plate 15 and the movable rods 904 to swing along the connection point with the base 1.

[0019] Working principle: When using air treatment equipment for flue gas purification: The operator will connect the flue gas pipe to flange 4 and connect the pipe above spray pipe 11 to the spray liquid (hydrogen peroxide solution can be used to purify flue gas). Flue gas enters the first chamber 2 through a pipe, passing through filter screen 5. Filter screen 5 (made of stainless steel, with a mesh size designed according to actual needs) filters out large particles in the flue gas. When filter screen 5 becomes clogged, the operator starts the servo motor 601. The output shaft of the servo motor 601 rotates, causing the rotating block 602 to rotate clockwise, which in turn moves the roller 603. The movement of roller 603 causes the crossbar 604 to move to the right along the outer wall of the limit rod 607, simultaneously stretching the spring 605. When the roller 603, which was in contact with the crossbar 604, disengages from the crossbar 604, the elasticity of the spring 605 causes the crossbar 604 to move quickly to the left, causing the rubber pad at the left end of the crossbar 604 to strike the filter screen 5. This dislodging of the large particles clogging the filter screen 5, to a certain extent, helps to remove clogged particles. To improve subsequent usage effectiveness, the number of times operators need to clean filter screen 5 can be reduced. Once the desired effect is achieved, the servo motor 601 can be turned off. When filter screen 5 is severely clogged and tapping it is ineffective, the operator can rotate the multiple bolts on top of filter screen 5 to remove it for cleaning. Simultaneously, the operator can rotate the multiple screws on the left side of the first housing 2 to open the door 3 and clean the large particles stored inside. If the tapping mechanism inside the first housing 2 is not running smoothly, the operator can open and rotate the multiple bolts on the front of the first housing 2 to remove the inspection door and clean or replace the tapping mechanism components inside the first housing 2. After cleaning the filter screen 5 and the large particles inside the first housing 2, the door 3 and filter screen 5 can be reinstalled. Start the fan 13. The fan 13 will transport the filtered flue gas to the second chamber 10 through the exhaust pipe 7 and the exhaust pipe 8 (both of which are equipped with one-way valves). Then, start the external water pump to draw the spray liquid into the spray pipe 11 and spray it out from multiple nozzles below the spray pipe 11 to purify the flue gas inside the second chamber 10. The purified gas will be discharged from the exhaust pipe 12 (the valve on the exhaust pipe 12 is a one-way valve). After all the flue gas has been purified, turn off the external water pump. The operator first disconnects flange 4 from the air intake pipe, and then removes support plate 905 from groove 906 by holding the handle on the left side of support plate 905. The operator then activates multi-stage hydraulic cylinder 901, causing the output end of cylinder 901 to extend and slide slider 902 along slot 903. This, in turn, rotates cross plate 15 and movable rod 904 along their connection point with base 1, causing the second housing 10 to tilt downwards and to the right. Once all the spray liquid has been drained, the operator closes multi-stage hydraulic cylinder 901 and then opens the valve on drain pipe 14 to discharge the spray liquid. Once the liquid is drained, the operator connects the spray pipe 11 to the high-pressure water gun to rinse the spray liquid inside the second chamber 10. The wastewater after rinsing is discharged from the drain pipe 14 to prevent excessive spray liquid residue inside the second chamber 10, thus reducing corrosion of the inner wall of the second chamber 10 and lowering maintenance costs. After the wastewater is completely drained, the operator controls the multi-stage hydraulic cylinder 901 to restore the horizontal plate 15 to its initial position, and then reinserts the support plate 905 into the groove 906 to support the horizontal plate 15 for future use.
