Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of particle separation equipment from gas, in particular to a waste gas dust removal device. BACKGROUND

[0002] Spray dust removal is a common method of separating dust particles from gas, which belongs to wet dust removal technology. By spraying water mist in the space or flow channel where the gas is located, the liquid droplets adhere to the dust particles and then settle down. It has the advantages of simple structure, high processing capacity, safety and reliability, and low investment cost.

[0003] Although the spray dust removal equipment has the above advantages, its special dust removal principle also brings a series of problems in the actual application process, such as: micro-fine particles cannot be captured, the dust capture efficiency is low, dust-containing wastewater is generated, it needs to be used with sludge treatment equipment, and it is frozen at low temperature.

[0004] Specifically, the existing spray dust removal equipment usually sprays water mist in the gas flow channel. The water mist cannot be fully mixed with the gas, and thus cannot fully adsorb the dust particles in the gas, resulting in poor dust removal effect.

[0005] Furthermore, by increasing the amount of water mist sprayed and increasing the distribution density of liquid droplets in the dust removal space, the dust adsorption effect can be improved to some extent. However, a large amount of water mist is sprayed, and the dust adhering to the liquid droplets falls freely and settles at the bottom of the spray dust removal equipment to form dust-containing wastewater. After sedimentation, sludge is formed at the bottom of the dust removal equipment, and the output and cleaning of the sludge are difficult, and the dust-containing wastewater also needs to be further treated by a series of sludge treatment equipment, increasing the system complexity and operation cost. If the dust-containing wastewater is not properly treated, it will cause secondary pollution.

[0006] In addition, the liquid droplets diffused in the dust removal space will flow with the airflow after adsorbing dust, and will be scattered in the dust removal space and adhere to the inner wall of the dust removal equipment. With the long-term use of the dust removal equipment, the dust on the inner wall of the dust removal equipment will gradually accumulate, affecting the internal space environment of the dust removal equipment. Not only is it difficult to completely remove, but also it affects the service life of the dust removal equipment.

[0007] To solve this problem, the technical personnel in this field mainly change the material of the plate to prevent adsorption, or increase the amount of water, or improve the atomization degree. However, this method will significantly increase the cost. Therefore, how to effectively remove the sludge in the spray dust removal equipment without significantly increasing the treatment cost through structural optimization and improvement is a technical problem to be solved. SUMMARY

[0008] The application aims to provide a waste gas dust removal device to solve the problems in the background.

[0009] To achieve the above object, the application provides the following technical scheme: a waste gas dust removal device, comprising a dust removal bin and a spray dust removal mechanism, wherein the spray dust removal mechanism is located inside the dust removal bin.

[0010] The spray dust removal mechanism comprises a plurality of spray plates, a plurality of spacer plates and a plurality of transmission rods, wherein the spray plates are fixedly connected with the transmission rods.

[0011] The transmission rods are hollow inside, and a plurality of spray heads one and spray heads two are arranged on the two side surfaces of the spray plates, and the spray heads one and the spray heads two are both in communication with the inside of the transmission rods.

[0012] The spacer plates are inserted between the spray plates, the spacer plates are provided with a limiting mechanism for limiting the horizontal movement thereof, and the spacer plates are provided with a plurality of stroke grooves.

[0013] A plurality of cooperative mechanisms for driving the spacer plates to move along the vertical direction are arranged above the transmission rods, the cooperative mechanisms comprise V-shaped blocks, the V-shaped blocks are located inside the stroke grooves, and the stroke grooves slide along the surfaces of the V-shaped blocks.

[0014] The transmission rods are provided with a reciprocating mechanism at one end and an intermittent water supply mechanism at the other end.

[0015] Preferably, the cross sections of the spray plates and the spacer plates are both zigzag.

[0016] Preferably, the spray heads one and the spray heads two are distributed in a staggered manner on the two sides of the spray plates.

[0017] And the spray heads one and the spray heads two are both located in the bending regions of the spray plates.

[0018] Preferably, the surfaces of the spray plates and the spacer plates are both rough.

[0019] Preferably, the reciprocating mechanism comprises a reciprocating electric cylinder and a synchronous frame, and the output end of the reciprocating electric cylinder is connected with the synchronous frame.

[0020] The synchronous frame is connected with the transmission rods.

[0021] Preferably, the stroke distance of the reciprocating electric cylinder is twice the distance between the spray plates and the spacer plates.

[0022] Preferably, the transmission rods are provided with an input port in communication with the inside thereof.

[0023] Preferably, the intermittent water supply mechanism is provided with multiple sealing sleeves and water inlets, and the sealing sleeves are connected to form a communication bin, which is connected to the input port;

[0024] The water inlet is connected to the communication bin, and the water inlet is connected to a pressurized water source.

[0025] Preferably, the length of the sealing sleeve is greater than the moving stroke length of the spray plate.

[0026] Preferably, the width of the communication bin is the same as the width of the input port, and the sealing sleeve is in sliding fit with the outside of the transmission rod.

[0027] Compared with the prior art, the beneficial effects of the present application are:

[0028] 1. The present application can improve the dust adsorption efficiency and comprehensiveness of dust removal by setting the reciprocating spray plate. The reciprocating spray plate can disturb the waste gas flow transmitted in the dust removal bin, change the original transmission direction of the dust-containing gas, and cooperate with the sprayed water mist to diffuse along the disturbed airflow, so as to quickly and fully mix with the dust-containing gas, thereby improving the comprehensiveness of the liquid droplet adsorbing dust particles.

[0029] 2. The present application can effectively collect the dust removal products by setting the interval plate between the spray plates. The sprayed water mist increases the humidity of the dust particles, which are respectively attached to the surfaces of the spray plates and the interval plates. The reciprocating movement of the spray plates can contact the interval plates, thereby extruding the dust attached to the surfaces of the spray plates and the interval plates, extruding the air between the dust particles, forming a dense dust sheet inside, and falling off under the action of gravity to output the dust removal products. This process does not cause secondary dust raising, improves the collection convenience of the dust removal products, and does not need to use sludge treatment equipment for further treatment.

[0030] 3. The present application can reduce the residual dust sheet by setting the cooperative mechanism to move the interval plate and the spray plate. The cooperative mechanism can move upward with the reciprocating movement of the spray plate, and through the mutual movement of the two, the extruded dust sheet can be rubbed into a strip or a particle, which reduces its adsorption force on the surfaces of the spray plate and the interval plate, and is more easily detached, thereby maintaining the good working condition of the surfaces of the spray plate and the interval plate.

[0031] 4. The present application can reduce the water source consumption and avoid the generation of dust-containing wastewater by setting the intermittent water supply mechanism. The intermittent water supply mechanism can supply water intermittently following the reciprocating movement period of the spray plate, thereby reducing the water source consumption. Only the sprayed water mist increases the humidity of the dust, so that the dust can have plasticity through extrusion, thereby avoiding the generation of dust-containing wastewater caused by a large amount of water spraying.

[0052] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0053] Please refer to Figures 1 to 12 The present application provides the following three embodiments:

[0054] Embodiment one:

[0055] Please refer to Figure 1 and Figure 2 A waste gas dust removal device, comprising a dust removal bin 100 and a spray dust removal mechanism 200, the spray dust removal mechanism 200 is located inside the dust removal bin 100.

[0056] The dust removal bin 100 has an air inlet, an air outlet and a discharge port, specifically, the air inlet and the air outlet are located at both ends of the dust removal bin 100, and the discharge port is located below the spray dust removal mechanism 200.

[0057] Please refer to Figure 1 and Figure 3 The spray dust removal mechanism 200 comprises a plurality of spray plates 210 and a plurality of transmission rods 240, the spray plates 210 are fixedly connected with the transmission rods 240, and the spacing between the spray plates 210 is the same.

[0058] Please refer to Figure 11 The transmission rod 240 is hollow inside.

[0059] Please refer to Figures 4 to 6 The two side surfaces of the spray plate 210 are respectively provided with a plurality of spray heads one 211 and spray heads two 212, and the spray heads one 211 and the spray heads two 212 are respectively connected with the inside of the transmission rod 240.

[0060] Specifically, please refer to Figure 5 Two flow dividing grooves one 213 and a plurality of flow dividing grooves two 214 are arranged inside the spray plate 210, the flow dividing grooves two 214 are vertically distributed, and the two ends of the flow dividing grooves two 214 are respectively connected with the two flow dividing grooves one 213, and the spray heads one 211 and the spray heads two 212 are respectively connected with the inside of the flow dividing grooves two 214.

[0061] Please refer to Figure 11The shunt groove 213 is connected with the inside of the transmission rod 240, and forms a water flow channel between the inside of the transmission rod 240 and the spray head 211 and the spray head 212.

[0062] Please refer to Figure 3 The transmission rod 240 is provided with a reciprocating mechanism 230 at one end. The reciprocating mechanism 230 includes a reciprocating electric cylinder 231 and a synchronous frame 232. The output end of the reciprocating electric cylinder 231 is connected with the synchronous frame 232, and the synchronous frame 232 is connected with the transmission rod 240.

[0063] The reciprocating electric cylinder 231 converts the circular motion into reciprocating linear motion, and serves as a power source for the reciprocating motion of the spray plate 210. The synchronous frame 232 cooperates with multiple transmission rods 240 to keep the spray plate 210 moving stably.

[0064] Please refer to Figure 3 The other end of the transmission rod 240 is connected with an intermittent water supply mechanism 250.

[0065] Please refer to Figure 10 and Figure 12 The transmission rod 240 is provided with an input port 241 connected with the inside of the transmission rod 240. The input port 241 serves as a water source input end of the inside space of the transmission rod 240.

[0066] Specifically, please refer to Figure 12 The intermittent water supply mechanism 250 is provided with multiple sealing sleeves 251 and water inlets 253. The sealing sleeves 251 form a communication bin 252 therebetween, and the communication bin 252 is connected with the input port 241.

[0067] The water inlet 253 is connected with the communication bin 252. The water inlet 253 is connected with a pressurized water source. Specifically, after the pressurized water source is input into the spray plate 210 through the input port 241, the pressurized water source can pass through the spray head 211 and the spray head 212 under the action of water pressure. The spray head 211 and the spray head 212 are both atomizing spray heads. After the water source is sprayed out of the spray head 211 and the spray head 212, atomized droplets are formed, and the atomized droplets are diffused in the gap between the spray plates 210. The atomized droplets adsorb the dust particles in the dust-containing waste gas and increase the moisture of the dust particles, so that the weight of the dust particles increases and the dust particles are separated from the waste gas, thereby achieving the effect of spray dust removal.

[0068] It is worth noting that the length of the sealing sleeve 251 is greater than the moving stroke length of the spray plate 210. The width of the communication bin 252 is the same as the width of the input port 241, and the sealing sleeve 251 is in sliding fit with the outside of the transmission rod 240.

[0069] The transmission rod 240 reciprocates in the intermittent water supply mechanism 250 under the drive of the reciprocating mechanism 230, when the input port 241 moves to the inside of the communication bin 252, the water source can be injected into the input port 241 by the communication bin 252, the transmission rod 240 is pushed to flow with the water source in the inside of the spray plate 210, and the water mist is sprayed out through the spray head one 211 and the spray head two 212, and the water mist is formed in the space on both sides of the spray plate 210.

[0070] When the transmission rod 240 moves, the input port 241 is out of the range of the communication bin 252 and enters the inside of the sealing sleeve 251, the sealing sleeve 251 seals the outside of the transmission rod 240, and the flow channel between the input port 241 and the communication bin 252 is cut off, that is, the water source cannot be input into the spray plate 210, and the spray head one 211 and the spray head two 212 do not spray water mist.

[0071] During the reciprocating movement of the transmission rod 240 and the spray plate 210, only when the input port 241 moves to the range of the communication bin 252, the spray head one 211 and the spray head two 212 spray water mist, so that the intermittent water spraying effect of the spray plate 210 is realized, on the one hand, the water source consumption is reduced, and on the other hand, the dust-containing waste water generated by a large amount of spraying water is prevented, and the cost of increasing dust-containing waste water treatment is increased.

[0072] It is worth noting that, please refer to Figure 3 and Figure 4 The cross section of the spray plate 210 is a broken line.

[0073] Please refer to Figure 6 The spray head one 211 and the spray head two 212 are staggered and distributed on both sides of the spray plate 210, and the spray head one 211 and the spray head two 212 are located in the bending area of the spray plate 210.

[0074] Specifically, the bending area of the spray plate 210 disturbs the flow of the input waste gas flow in the dust removal bin 100, not only increases the path of the waste gas through the spray plate 210, but also increases the probability of contact between the dust particles and the surface of the spray plate 210, so that the dust separation effect can be improved.

[0075] It is worth noting that the surface of the spray plate 210 is rough, and the spray plate 210 after surface roughening treatment has stronger adhesion, which can ensure that the dust adheres to its surface after being wetted.

[0076] During the dust removal process, the dust-containing waste gas is input into the inside of the dust removal bin 100 through the gas inlet, the transmission rod 240 reciprocates in the intermittent water supply mechanism 250 under the drive of the reciprocating mechanism 230, and the spray plate 210 reciprocates in the dust removal bin 100 with the transmission rod 240.

[0077] When the input port 241 moves into the range of the connecting bin 252, the water source of the connecting spray plate 210 is input, and the spray heads one 211 and two 212 spray water mist, realizing the effect of intermittent water spraying of the spray plate 210, on the one hand, reducing the water source consumption, on the other hand, preventing a large amount of spraying water from generating dust-containing wastewater.

[0078] During the diffusion process of the water mist, part of it combines with the dust particles in the exhaust gas, increasing the weight of the dust particles, so that they are separated from the exhaust gas; the other part adheres to the surface of the spray plate 210 for comprehensive adsorption of dust particles.

[0079] When the spray plate 210 moves back and forth in the dust removal bin 100, the spray plate 210 changes the airflow direction when the exhaust gas is input, causing disturbance to the airflow, so that the dust-containing exhaust gas is fully mixed with the water mist, increasing the humidity of the dust-containing exhaust gas, and the liquid droplets adsorb dust. When following the disturbed airflow drifts in the moving range of the spray plate 210, the liquid droplets containing dust and the humidified dust particles are adsorbed by the liquid droplets on the surface of the spray plate 210 after contacting the surface of the spray plate 210, so as to adsorb the dust particles on the surface of the spray plate 210, realizing the effective separation of the dust particles in the exhaust gas.

[0080] After being humidified, the dust particles gradually accumulate on the surface of the spray plate 210 to form a dust block. As the accumulated dust particles gradually increase, when the weight of the dust block is greater than its adhesion on the spray plate 210, the dust block falls off the spray plate 210. In this process, since the dust particles in the dust block are all humidified by liquid droplets, the mutual adhesion between the dust particles is much greater than the adhesion between the original dispersed dust particles. Therefore, the dust block can maintain the accumulated state during the falling process, and the problem of secondary dust raising will not occur.

[0081] The falling dust block is output by the discharge port of the dust removal bin 100. The water content in the accumulated dust block is low, only the humidified dust particles, and the wastewater content is low, so that systematic dehydration treatment is not required, and subsequent harmless treatment can be performed.

[0082] The exhaust gas after spray dust removal is discharged from the gas outlet for subsequent treatment of the exhaust gas.

[0083] Example Two:

[0084] Based on the content of the above example one, another example is proposed:

[0085] Please refer to Figure 1 and Figure 3 , the spray dust removal mechanism 200 further comprises a plurality of spacing plates 220.

[0086] The spacing plates 220 are inserted between the spray plates 210, and the spacing between the spacing plates 220 is the same as the spacing between the spray plates 210.

[0087] It is worth noting that the stroke distance of the reciprocating cylinder 231 is twice the distance between the spray plate 210 and the spacing plate 220. It is ensured that the spray plate 210 can contact the spacing plate 220 when the reciprocating cylinder 231 is in the maximum extension state and the minimum extension state.

[0088] The cross section of the spacing plate 220 is a broken line, and the bending segments of the spacing plate 220 are distributed in parallel with the bending segments of the spray plate 210.

[0089] The surface of the spacing plate 220 is rough.

[0090] The spray plate 210 repeatedly contacts the surface of the spacing plate 220 under the drive of the reciprocating mechanism 230. In this process, one side of the spray plate 210 moves towards the spacing plate 220, the space volume of this side is reduced, and positive pressure is generated to squeeze out the internal waste gas and water mist; on the contrary, the distance between the other side of the spray plate 210 and the other spacing plate 220 increases, the space volume increases, and negative pressure is generated to suck the waste gas in the dust removal bin 100 into the interior.

[0091] In summary, the plurality of spray plates 210 repeatedly move between the spacing plates 220, which can respectively suck and discharge the waste gas, further increase the flowability of the waste gas in the spray dust removal mechanism 200, improve the overall degree of adsorbing dust particles by the spray plate 210 and the spacing plate 220, and thus improve the separation effect of dust from the waste gas.

[0092] It is worth noting that after the spray plate 210 contacts the spacing plate 220, the dust particles gathered on the surface of the spray plate 210 and the spacing plate 220 are squeezed to discharge the internal air and form a cake, and as the dust particles gradually gather on the surface of the spray plate 210 and the spacing plate 220, the weight of the cake also increases, and finally the cake is separated from the spray plate 210 and the spacing plate 220 under the impact vibration when the spray plate 210 and the spacing plate 220 are attached.

[0093] The falling cake is output by the discharge port of the dust removal bin 100, the water content of the gathered cake is less, which is only the dust particles in a wet state, and the wastewater content is low, so that systematic dehydration treatment is not required, and subsequent harmless treatment can be performed.

[0094] The waste gas after spray dust removal is discharged from the gas outlet for subsequent treatment of the waste gas.

[0095] Example Three:

[0096] Based on the above content in Example Two, another example is proposed:

[0097] Please refer to Figures 7 to 10The transmission rod 240 is provided with a plurality of driving interval plates 220 moving along the vertical direction, and the cooperative mechanism 242 is provided above the transmission rod 240, the cooperative mechanism 242 comprises a V-shaped block 2421, and the V-shaped block 2421 is located inside the stroke groove 222 and slides along the surface of the V-shaped block 2421.

[0098] Please refer to Figure 8 The interval plate 220 is provided with a limiting mechanism 221 limiting the horizontal movement of the interval plate 220, and the limiting mechanism 221 is a limiting rod, and the two ends of the limiting rod are fixedly connected with the inner wall of the dust removal bin 100.

[0099] The interval plate 220 is provided with a plurality of stroke grooves 222 for further limiting the movement stroke of the interval plate 220 in the vertical direction.

[0100] Specifically, when the spraying plate 210 reciprocates, and the spraying plate 210 is about to be attached to the surface of the interval plate 220, the transmission rod 240 moving synchronously with the spraying plate 210 moves in the stroke groove 222, and simultaneously drives the V-shaped block 2421 to move.

[0101] Specifically, when the transmission rod 240 reciprocates, the V-shaped block 2421 can be driven to move in the stroke groove 222, the limiting mechanism 221 limits the interval plate 220, so that the interval plate 220 cannot move horizontally, but can only move vertically, and the interval plate 220 falls under the action of its own gravity, that is, the top end inner wall of the stroke groove 222 is attached to the surface above the transmission rod 240.

[0102] The V-shaped block 2421 moves horizontally with the transmission rod 240, at this time, the slope surface of the V-shaped block 2421 gradually contacts the upper end inner wall of the stroke groove 222, in this process, the stroke groove 222 moves along the surface of the V-shaped block 2421, so that the stroke groove 222 rises along the slope surface of the V-shaped block 2421, that is, when the spraying plate 210 reciprocates, the interval plate 220 moves vertically upward along the slope surface.

[0103] It is worth noting that the spraying plate 210 and the interval plate 220 are attached with dust, after the spraying plate 210 and the interval plate 220 extrude the dust, the interval plate 220 moves upward under the driving of the V-shaped block 2421, so that the interval plate 220 and the spraying plate 210 produce relative movement in the vertical direction, and the extruded dust cake can be rubbed, that is, under the joint action of the horizontal extrusion force and the vertical force, the extrusion force in the horizontal direction extrudes and compacts the attached dust, and then the vertical force rubs, so that the dust cake forms a strip, reduces the attachment area on the surface of the spraying plate 210 and the interval plate 220, and thus reduces the adhesion.

[0104] When the interval plate 220 is separated from the spray plate 210, the dust strip formed by kneading loses the adhesion and falls from the inside of the spray dust removal mechanism 200 under the action of gravity and enters the discharge port. The good working conditions of the spray plate 210 and the interval plate 220 can be maintained.

[0105] The fallen dust strip is output by the discharge port of the dust removal bin 100, the dust strip in the gathered state is extruded and kneaded, the inside is more dense, no secondary dust is generated in the falling process, and the dust particles are all in the wet state, the waste water content is low, no systematic dehydration treatment is needed, and subsequent harmless treatment can be performed.

[0106] The waste gas after the spray dust removal is discharged by the gas outlet and subjected to subsequent treatment.

[0107] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of the equivalent elements of the claims are intended to be embraced in the present application. Any reference signs in the claims should not be considered as limiting the claims involved.
