Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a wet smoking dust removal device. Background Technique

[0002] The wet dust collector is commonly known as a "demister". It makes the dust-containing gas come into close contact with a liquid (usually water), and uses the inertial collision of water droplets and particles or the full mixing effect of water and dust and other effects to capture particles or make the particles larger or stay in a fixed container to achieve the separation effect of water and dust.

[0003] According to the disclosed patent CN203609988U, a wet smoking dust removal device includes a smoking pipe, a fan, a blowing pipe, a bubble generator, a liquid storage tank, and an exhaust pipe. The smoking pipe is flexible and installed on the fan. One end of the blowing pipe is connected to the fan and the other end is connected to the bubble generator. The bubble generator is placed in the liquid storage tank, and the upper end of the liquid storage tank is connected to the exhaust pipe. For the wet smoking dust removal device disclosed by the utility model, the gas flow resistance is low and constant, it is suitable for absorbing various types of smoke and dust, and it is convenient for maintenance and upkeep. At the same time, the device has a simple structure, which reduces the production cost. In the process of implementing the utility model, the inventor found that at least the following problems in the prior art have not been solved. The smoke and dust inside the gas are absorbed by connecting the blowing pipe and the bubble generator. During use, when the gas is transported through the blowing pipe into the liquid storage tank and comes into contact with the liquid for dust removal treatment, the dust removal liquid is only statically placed in the liquid storage tank. As a result, after the gas is transported into the liquid storage tank, it cannot fully contact the dust inside the gas. At the same time, after long-term dust removal use, a large amount of fixed dust will be doped in the liquid, which affects the subsequent dust removal quality. When the liquid is replaced regularly, it not only causes waste of the dust removal liquid, but also affects the dust removal quality due to untimely replacement. Therefore, a new technical solution needs to be designed to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a wet smoking dust removal device to solve the technical problem that the current static placement of the dust removal liquid affects the insufficient dust removal quality of the transported gas.

The drain pipes and the spraying nozzles are both located above the outer side of the air delivery pipe, and the side of the connecting elbow away from the connecting pipe is fixedly connected and communicated with the bottom of the water delivery pipe;

[0007] At the bottom of the inner side of the separation box, a liquid guide box is fixedly installed, and the liquid guide box is located below the outer side of the air delivery pipe. Drainage grooves are formed on the sides of the separation box and the static box, and the bottom of the side of the liquid guide box close to the static box is communicated with the drainage groove.

[0008] Preferably, a liquid suction pump is fixedly installed on the side of the connecting elbow close to the static box, and a one-way valve is fixedly installed on the side of the connecting elbow close to the water delivery pipe.

[0009] Preferably, a water absorption box is slidably installed on the top of the inner side of the separation box.

[0010] Preferably, a sealing cover plate is fixedly installed on the side surface of the water absorption box, and the sealing cover plate is movably located outside the separation box. A sealing gasket is fixedly adhered to the side surface of the sealing cover plate. An activity groove is formed inside the side of the separation box, and the sealing gasket is hermetically inserted into the activity groove. A hand pulling frame is fixedly installed on the outer surface of the sealing cover plate.

The drain pipes 28 and the spraying nozzles 29 are both located above the outside of the gas transmission pipe 13, and one side of the connecting elbow 25 away from the connecting pipe 21 is fixedly connected and communicated with the bottom of the water transmission pipe 26. A liquid guiding frame 24 is fixedly installed at the inner bottom of the separation box 1, and the liquid guiding frame 24 is located below the outside of the gas transmission pipe 13. Drainage grooves 23 are formed on the sides of the separation box 1 and the static frame 2, and the bottom of the side of the liquid guiding frame 24 close to the static frame 2 is communicated with the drainage groove 23. Through the setting of the static frame 2, and under the communication effect of the liquid extraction pipe 22 and the connecting elbow 25, and by arranging the drain pipe 28 above the outside of the gas transmission pipe 13, the dust removal water can fully contact and perform dust removal treatment on the gas discharged from the bottom of the gas transmission pipe during the gravity flow process, and at the same time, the dust removal water located above the inside of the static frame 2 can be extracted again and conveyed into the water transmission pipe 26 for recycling, improving the utilization rate of the dust removal water while flowing and utilizing the dust removal water, ensuring that a large amount of impurities will not accumulate in the dust removal water and affect its dust adsorption and cleaning efficiency for the dust in the gas, and further improving the dust removal quality of the gas.

[0027] Specifically, refer to Figures 1 to 4, a liquid extraction pump 51 is fixedly installed on the outer side of the connecting elbow 25 near the static box 2, and a one-way valve 5 is fixedly installed on the outer side of the connecting elbow 25 near the water delivery pipe 26. Through the structural functions of the one-way valve 5 and the liquid extraction pump 51, the extraction and transportation treatment of the dust removal liquid after standing can be realized.

[0028] Furthermore, referring to Figures 1 to 4 , a water absorption frame 3 is slidably installed on the inner top of the separation box 1. Ventilation mesh frames 31 are fixedly inlaid inside both ends of the outer side of the water absorption frame 3. A discharge pipe 41 is vertically and fixedly communicated with the top of the separation box 1. A gas collection hood 4 is fixedly communicated with the bottom of the discharge pipe 41. And the ventilation mesh frame 31 is located between the lower part of the gas collection hood 4 and the upper part outside the drain pipe 28. An air extraction pump 42 is fixedly installed on the outer side of the discharge pipe 41. Through the structural function of the air extraction pump 42, the water body after dust removal can be extracted and discharged in a timely and rapid manner.

[0029] It should be noted that, referring to Figures 1 to 4 , a sealing cover plate 32 is fixedly installed on the side surface of the water absorption frame 3, and the sealing cover plate 32 is movably located outside the separation box 1. A sealing gasket 34 is fixedly adhered to the side surface of the sealing cover plate 32. An activity groove 33 is formed inside the side of the separation box 1, and the sealing gasket 34 is hermetically inserted into the activity groove 33. A hand-pulling frame 35 is fixedly installed on the outer surface of the sealing cover plate 32. Through the structural function of the sealing gasket 34, the activity groove 33 can be sealed and protected to prevent the dust removal water body from moving out of the activity groove 33 and causing waste in the use of the dust removal water body.

[0030] It should be noted that, referring to Figures 1 to 4 , guide blocks 36 are fixedly installed on the surfaces of both ends of the outer side of the water absorption frame 3. Guide grooves 37 are formed at both ends inside the separation box 1, and the guide blocks 36 are slidably inserted into the guide grooves 37. Under the guiding and sliding action of the guide grooves 37 on the guide blocks 36, the movement and pulling of the water absorption frame 3 are ensured.

[0031] It is worth introducing that, referring to Figures 1 to 4 , a control valve 52 is fixedly installed on the outer side of the water delivery pipe 26. Through the structural function of the control valve 52, the fluidity of the water delivery pipe 26 is controlled.

[0032] During operation, the dust removal water required for gas dust removal and the gas to be dusted are respectively transported through the water delivery pipe 26 and the gas delivery pipe 13. The control valve 52 is opened to transport the dust removal water into the drain pipe 28, and then the dust removal water is evenly sprayed downward from above the top of the gas delivery pipe 13 through multiple drain pipes 28 and spray nozzles 29. Meanwhile, the gas to be dusted is discharged through the exhaust holes 14, so that the dust removal water can directly contact the gas located below the spray nozzles 29 under the action of gravity, adsorb the dust and impurities inside the gas, and then directly drip into the liquid guide frame 24 under the action of gravity. Under the drainage action inside the liquid guide frame 24, the water body adsorbed with dust and impurities is transported through the drain tank 23 to the static frame 2. After the water body inside the static frame 2 is statically precipitated for a period of time, the water body is stratified, and the solid impurities can be precipitated at the inner bottom of the static frame 2, while the clean water body is above the static frame 2. Then, the liquid extraction pump 51 is synchronously started to operate, and the clean water body is extracted and transported through the liquid extraction pipe 22 into the connection pipe 21. Then, under the transportation action of the connecting elbow 25, the water body is re-transported into the water delivery pipe 26 and then transported into the separation box 1 to re-extract and transport the precipitated water body for dust removal use. The air extraction pump 42 is synchronously started to operate to generate a corresponding negative pressure in the exhaust pipe 41 and the air collection hood 4, and the dust-removed gas is extracted from the top of the separation box 1, so that the dust-removed gas can flow through the breathable mesh frame 31 and the water absorption frame 3. Combined with the water absorption material inside the water absorption frame 3, the flowing gas is subjected to water treatment. When the water absorption effect of the water absorption material inside the water absorption frame 3 is insufficient, the operator holds the hand-pulled frame 35 and pulls it, driving the sealing cover plate 32 and the sealing gasket 34 to move out of the movable groove 33, and then pulling out the water absorption frame 3 from the movable groove 33 synchronously to replace the water absorption material inside it, ensuring sufficient water absorption treatment for the dust-removed gas.
