Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, in particular to a VOC waste gas treatment device. Background Art

[0002] VOC waste gas is organic waste gas, a general term for volatile organic compounds. VOC waste gas is produced in many factories today, such as ink in printing factories, waste gas from paint spraying rooms, waste gas from rubber factories, etc. In order to avoid VOC waste gas from polluting the air after being discharged, various treatment equipment is generally required to treat VOC waste gas and remove the acid and alkali components, dust, organic pollutants, etc. inside the VOC waste gas.

[0003] After searching, the publication number CN218249379U, application date 2022.04.22 discloses a high-efficiency VOC waste gas treatment equipment, which relates to the field of waste gas treatment, including a purification box, the left and right ends of the purification box are respectively provided with an air inlet and an air outlet, and the interior of the purification box is connected with a dust collecting plate, several activated carbon adsorption boxes and a heating plate. The dust collecting plate is arranged on the side close to the air inlet, and the heating plate is arranged between several of the activated carbon adsorption boxes. An inert gas duct is installed on the top of the purification box, and several air nozzles are fixedly installed on the inner top wall of the purification box. The input ends of several of the air nozzles pass through the purification box and are connected to the inert gas duct.

[0004] However, it still has the following disadvantages in actual use:

[0005] The above-mentioned high-efficiency VOC waste gas treatment equipment uses a sliding dust collecting plate to block dust and other impurities during use. However, due to the lack of limit and sealing measures on the dust collecting plate, the high-speed exhaust gas entering during use will exert force on the dust collecting plate, causing the dust collecting plate to shake and become unstable, which may cause waste gas leakage.

[0006] 2. The aforementioned high-efficiency VOC waste gas treatment equipment uses an inert gas duct and a nozzle to treat waste gas. However, since the nozzle cannot change the jet angle, this method has a limited impact on the waste gas, which may affect the efficiency and effectiveness of waste gas treatment. To this end, we provide a VOC waste gas treatment device to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a VOC waste gas treatment device, which is convenient for workers to quickly disassemble and replace the dust collecting plate by setting an installation component, saving time and effort, high work efficiency, and good stability, avoiding the dust collecting plate from detaching during use, and using the adjustment component to push multiple adjustment plates on the inside to move, and then adjust the angle of the nozzle under the action of the hose, so that the inert gas can be sprayed through the inclined nozzle to slow down the flow rate of the waste gas, so that the waste gas can be fully treated, and the waste gas treatment efficiency and effect are improved.

[0008] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0009] The utility model is a VOC waste gas treatment device, comprising a purification box and a homogenizing plate installed on one side of the purification box, a mounting groove is provided on one side of the front end face of the purification box, a movable groove is provided at the top and bottom edges of the inner wall of one side of the mounting groove, a mounting component is provided inside the movable groove, and an adjustment component is evenly spaced along the circumferential direction on the other side of the interior of the purification box;

[0010] The mounting assembly includes a push plate and a connecting column fixedly connected to the center of its inner wall, the other end of the connecting column passes through the limiting hole on the outer wall of the movable groove and is connected to the movable plate;

[0011] The regulating component comprises a gas conduit and a hose evenly spaced inside the gas conduit in a horizontal direction, and the other end of the hose passes through the outer wall of the purification box and is connected to the corresponding nozzle.

[0012] The utility model is further configured such that air ports are provided at the center positions of the outer walls on both sides of the purification box, activated carbon adsorption boxes are evenly spaced on the other side of the interior of the purification box, and limiting frames are provided on one side of the top and bottom ends of the interior of the purification box.

[0013] The utility model is further configured such that the limiting frame is slidably connected to the sliding frame inside, a clamping groove is provided at the top and bottom edges of the outer wall of one side of the sliding frame, and a sealing gasket is bonded to the inner wall of the sliding frame.

[0014] The utility model is further configured such that support plates are fixedly connected to the upper and lower inner walls of the sliding frame, and dust collecting plates are detachably mounted on both sides between the upper and lower adjacent support plates.

[0015] The utility model is further configured such that a connecting rod is fixedly connected to the center position of the outer wall of the movable plate, the other end of the connecting rod passes through the through hole on the fixed plate and is connected to the clamping block, and a spring is sleeved on the outer wall of the connecting rod.

[0016] The utility model is further configured such that the spring is located between the fixed plate and the clamping block, and the outer wall of the fixed plate is fixed on the inner wall of the movable groove.

[0017] The utility model is further configured such that an adjustment frame is sleeved on the outer wall of the nozzle, and a threaded rod is installed at the center position of one end surface of the adjustment frame.

[0018] The utility model is further configured such that the other end of the threaded rod sequentially passes through the threaded holes on the adjacent adjustment frame and the purification box and is connected to the rotary plate, and the threads on the outer wall of the threaded rod engage with the internal threads in the wall of the adjacent threaded hole.

[0019] The utility model has the following beneficial effects:

[0020] The utility model provides an installation component, which drives the card block to move under the action of the elastic properties of the spring, thereby achieving or canceling the limiting effect between the card block and the corresponding card slot, making it convenient for workers to quickly disassemble and replace the dust collecting plate, saving time and effort, high work efficiency, and good stability, avoiding the dust collecting plate from detaching during use, and solving the problem that the above-mentioned high-efficiency VOC waste gas treatment equipment blocks dust and other impurities through the sliding dust collecting plate when in use.

DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying 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.

[0033] Example 1

[0034] See also Figures 1 to 5 The utility model is a VOC waste gas treatment equipment, including a purification box 1 and a homogenizing plate 102 installed on one side of the interior thereof. A mounting groove 106 is provided on one side of the front end face of the purification box 1, and movable grooves 106a are provided at the top and bottom edges of the inner wall of one side of the mounting groove 106. A mounting component 2 is provided inside the movable groove 106a; the mounting component 2 includes a push plate 201 and a connecting column 201a fixedly connected to the center position of the inner wall thereof, and the other end of the connecting column 201a passes through the limiting hole on the outer wall of the movable groove 106a and is connected to the movable plate 202.

[0035] Specifically, air ports 101 are provided at the center of the outer walls on both sides of the purification box 1, and activated carbon adsorption boxes 103 are evenly spaced on the other side of the interior of the purification box 1. A limiting frame 104 is provided on the top and bottom of the interior of the purification box 1. The interior of the limiting frame 104 is slidably connected to a sliding frame 105. A card groove 105a is provided at the top and bottom edges of the outer wall of one side of the sliding frame 105. A sealing gasket 105b is bonded to the inner wall of the sliding frame 105. The inner wall of the sliding frame 105 is provided with a sealing gasket 105b. There are support plates 107 fixedly connected to the bottom, and dust collecting plates 108 are detachably installed on both sides between the upper and lower adjacent support plates 107. A connecting rod 203 is fixedly connected to the center position of the outer wall of the movable plate 202, and the other end of the connecting rod 203 passes through the through hole on the fixed plate 204 and is connected to the block 206. A spring 205 is sleeved on the outer wall of the connecting rod 203, and the spring 205 is located between the fixed plate 204 and the block 206. The outer wall of the fixed plate 204 is fixed to the inner wall of the movable groove 106a.

[0036] Furthermore, the homogenizing plate 102, the activated carbon adsorption box 103, the dust collecting plate 108, etc. are all existing technologies, so they will not be described in detail here. The push plate 201 and the movable plate 202 are connected by the connecting column 201a, which plays the role of connecting transmission. The limit frame 104 plays the role of limiting the sliding of the sliding frame 105. The sealing gasket 105b can increase the sealing of the contact surface between the inner wall of the sliding frame 105 and the inner wall of the installation groove 106 to avoid exhaust gas leakage. The block 206 and the movable plate 202 are connected by the connecting rod 203, which plays the role of connecting transmission. Under the action of the elastic performance of the spring 205, the block 206 can be driven to move, thereby limiting the sliding frame 105 and improving stability.

[0037] The operation process of this embodiment is as follows: when VOC waste gas needs to be treated, it is introduced into the purification box 1 through the air inlet 101 outside the purification box 1, and then the VOC waste gas introduced is dispersed by the homogenizing plate 102, and then the dust collecting plate 108 is used to filter the dust, impurities, etc. in the waste gas, and the filtered waste gas adsorbs toxic substances under the action of multiple groups of activated carbon adsorption boxes 103. When the purification box 1 is in operation for a long time, the upper and lower push plates 201 are pushed outward, and the push plates 201 are forced to move outward, and the inner wall of the push plate 201 is connected to the movable plate 202 through the connecting column 201a, so when the push plate 201 moves, it will drive the movable plate 202 to move under the action of the connecting column 201a, and the inner wall of the movable plate 202 is connected to the block 206 through the connecting rod 203, so when the movable plate 202 moves, it will be connected to the connecting rod 203. 03 drives the block 206 to move and squeezes the spring 205. At this time, the block 206 can be moved out of the slot 105a on the outer wall of the sliding frame 105, and then the sliding frame 105 can be pulled out under the guiding action of the limit frame 104, and the dust collecting plate 108 can be replaced. In the same way, when replacing and installing, the sliding frame 105 is installed inside the purification box 1 using the limit frame 104, and the sealing gasket 105b on the inner wall of the sliding frame 105 is pressed against the inner wall of the installation slot 106, and then the force on the push plate 201 is stopped. At this time, the elastic performance of the spring 205 can bounce the block 206 into the corresponding slot 105a, achieving the purpose of limiting the sliding frame 105 and completing the installation, thereby facilitating the staff to quickly disassemble and assemble the sliding frame 105, saving time and effort, and having high work efficiency and good stability.

[0038] Example 2

[0039] See also Figure 2 and Figure 6 Based on Example 1, the difference from the first embodiment is that: an adjustment component 3 is provided, and the adjustment component 3 includes a gas conduit 301 and a hose 301a evenly spaced inside the gas conduit 301 in the horizontal direction. The other end of the hose 301a passes through the outer wall of the purification box 1 and is connected to the corresponding nozzle 302. This solves the problem that the existing high-efficiency VOC waste gas treatment equipment uses an inert gas conduit and an air nozzle to treat the waste gas during use. However, since the air nozzle cannot change the jet angle, this method has little impact on the waste gas, which may affect the efficiency and effect of the waste gas treatment.

[0040] Specifically, an adjustment frame 303 is sleeved on the outer wall of the nozzle 302, and a threaded rod 304 is installed at the center position of the end face of one side of the adjustment frame 303. The other end of the threaded rod 304 passes through the threaded holes on the adjacent adjustment frames 303 and the purification box 1 and is connected to the rotary plate 305 in sequence. The threads on the outer wall of the threaded rod 304 engage with the internal threads in the wall of the adjacent threaded hole.

[0041] Furthermore, the angle of the nozzle 302 can be changed through the hose 301a, and the rotating plate 305 drives the threaded rod 304 to rotate. Since the threads on the outer wall of the threaded rod 304 engage with the internal threads in the wall of the adjacent threaded hole, when the threaded rod 304 rotates, it will push the multiple adjustment frames 303 inside to move, thereby achieving the purpose of adjusting the angle of the nozzle 302.

[0042] The operating process of this embodiment is as follows: when the exhaust gas enters the interior of the purification box 1, the heated inert gas can be introduced into the interior of the purification box 1 through the gas duct 301. At this time, the rotating plates 305 around the outer side are rotated, and the rotating plates 305 are driven by force to drive the threaded rod 304 to rotate, and the external threads on the outer wall of the threaded rod 304 are engaged with the internal threads in the wall of the corresponding threaded hole on the end face of the purification box 1. Therefore, during the rotation of the threaded rod 304, it will continue to move toward the interior of the purification box 1 and push the multiple adjustment racks 303 inside, so that the adjustment rack 303 drives the nozzle 302 inside it to tilt to one side under the action of the hose 301a, thereby achieving the purpose of adjusting the angle of the nozzle 302. Therefore, when the exhaust gas is introduced, the flow rate of the exhaust gas can be slowed down by spraying inert gas, so that the exhaust gas can be fully treated, thereby improving the efficiency and effect of exhaust gas treatment.
