Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a bag dust collector for high-temperature furnace tail gas. Background Art

[0002] A bag dust collector is a dry dust filtering device suitable for capturing fine, dry, non-fibrous dust. It has a wide range of applications and can not only provide a clean working environment and protect the health of workers, but also reduce damage to equipment and extend the service life of equipment. When air enters the bag dust collector, large dust particles will be directly isolated by the bags and fall into the ash hopper, while small dust particles will be blocked by the bags and adsorbed on the surface of the bags, requiring external forces such as blowing or vibration to be processed.

[0003] After the dust filtered by the existing bag filter is discharged into the ash hopper, the dust is still in a dry state. When the staff performs secondary treatment on the dust in the ash hopper, the dust in the ash hopper is easy to float up and down again and return to the air, affecting the air environment and causing great inconvenience. Utility Model Content

[0004] Based on the above description, the utility model provides a bag dust collector for high-temperature furnace exhaust gas to solve the problem that dust is easily re-floated and causes air pollution when the ash hopper of the existing bag dust collector discharges ash.

[0005] The utility model solves the above-mentioned technical problem with the following technical solution: a bag dust collector for high-temperature furnace exhaust gas, comprising a bag dust collector, a water storage hopper is installed on the outside of the bag dust collector, a filtering structure for solid-liquid separation is arranged on the inside of the water storage hopper, a humidifying device for humidifying dust is arranged on the inside of the filtering structure, a dust removal net is installed on the inside of the filtering structure to prevent dust from sticking to the humidifying device, and a water supply component connected to the humidifying device is arranged on the outside of the water storage hopper.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, a notch is provided in the center of the surface of the water storage hopper close to the bag-type dust collector, and a buckle plate buckled to the outside of the discharge port of the bag-type dust collector is installed inside the notch.

[0008] Furthermore, a column is provided at a corner of the inner wall of the water storage hopper away from the bag dust collector, and a water exchange port located between two adjacent columns is provided on the outer side of the water storage hopper.

[0009] Furthermore, the filtering structure is composed of a dust hopper and a filtering layer. The dust hopper is installed on the inner side of the water storage hopper and fits with the end of the column close to the bag dust collector. The inner wall of the dust hopper close to the bag dust collector is provided with filter holes distributed in a rectangular array, and the filtering layer is arranged on the inner side of the dust hopper.

[0010] Furthermore, the humidification device is composed of a water supply device, which is installed on the inner side of the dust storage hopper and located on the side of the filter layer close to the bag dust collector. The water supply device is arranged in a mesh shape, and an array-distributed water outlet is provided on the side of the water supply device close to the bag dust collector.

[0011] Furthermore, a pipe interface is provided on the outside of the water storage hopper, and there are two pipe interfaces, one of which is located between two adjacent columns, and the other pipe interface corresponds to the position of the water supply equipment. The dust removal net is installed on the inner side of the dust storage hopper and fits onto the side of the water supply equipment close to the bag dust collector.

[0012] Furthermore, the water supply assembly is composed of a water pump and a water supply pipe. The water pump is installed on the outside of the water storage bucket. The water supply pipe is installed at one end of the water pump and passes through a pipe interface away from the bag dust collector. The water pump is electrically connected to the water supply equipment.

[0013] Furthermore, the water inlet pipe of the water supply device passes through the dust storage hopper and the other pipe interface and is connected to the water pump. A sealing sleeve is installed between the inner side of the pipe interface and the water supply pipe and the water inlet pipe of the water supply device.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] The utility model uses a water supply device, a filter layer and a dust unloading net arranged in the dust hopper, and cooperates with a water pump connected between the water supply device and the water hopper. The space between the dust hopper and the water hopper can be used for liquid storage. The water pump can introduce the water stored in the water hopper into the dust hopper, and the water is evenly discharged through the water supply device and then re-enters the water hopper along the filter layer to form a circulation. During the process, the water supply device can form an uninterrupted water supply. When dust falls into the dust hopper, it can be humidified by the water circulating in the dust hopper to increase the weight, which effectively avoids the secondary floating of the dust during subsequent treatment. After falling into the dust hopper, the dust is isolated by the dust unloading net without contacting other structures and can be discharged from the dust hopper alone, which is convenient for subsequent secondary treatment operations. The impurities in the sewage generated after the dust is humidified will be filtered by the filter layer during the circulation process, which is convenient for the use of the water pump and the water supply device, and increases the use time and utilization efficiency of the liquid.

After the docking is completed, the buckle plate 3 can be reset and buckled on the outside of the discharge port of the bag dust collector 1 to fix the water storage bucket 2. The operation is simple and it is convenient for the water storage bucket 2 to be disassembled and assembled. A column 24 is provided at the corner of the inner wall away from the bag dust collector 1. The column 24 is used to support the dust storage hopper 4 after it is installed inside the water storage hopper 2. A space can be divided between the water storage hopper 2 and the dust storage hopper 4 for circulating and storing liquid. A water exchange port 23 located between two adjacent columns 24 is provided on the outside of the water storage hopper 2. A sealing plug is installed on the outside of the water exchange port 23 to ensure that the water storage hopper 2 is in a sealed state. The staff can also remove the sealing plug to replace the liquid in the water storage hopper 2 to ensure the cleanliness of the liquid.

[0028] See also Figure 6 The filtering structure is composed of a dust hopper 4 and a filter layer 5. The dust hopper 4 is installed on the inner side of the water hopper 2 and fits with the end of the column 24 close to the bag dust collector 1. The inner wall of the dust hopper 4 close to the bag dust collector 1 is provided with filter holes 41 distributed in a rectangular array. The filter layer 5 is arranged on the inner side of the dust hopper 4. The filter layer 5 can filter the wastewater generated by the wet dust, and block the fine particles in the wastewater in the water hopper 2, while the liquid can flow back into the water hopper 2 through the filter holes 41, and form a water circulation with the water pump 8 and the water supply equipment 6. At the same time, the filtered wastewater is also convenient for the water pump 8 and the water supply equipment 6 to extract and use, avoiding the blockage of particles in the equipment.

[0029] See also Figure 3 The humidification device is composed of a water supply device 6, which is installed on the inner side of the dust storage hopper 4 and is located on the side of the filter layer 5 close to the bag-type dust collector 1. The water supply device 6 is arranged in a mesh shape. The side of the water supply device 6 close to the bag-type dust collector 1 is provided with an array of water outlets 61. The water supply device 6 can evenly discharge the liquid from the side close to the bag-type dust collector 1 to humidify the dust falling into the water storage hopper 2. At the same time, affected by the shape characteristics of the water supply device 6, the water used for dust humidification can pass through the water supply device 6 and enter the filter layer 5 for circulation.

[0030] See also Figure 2 A pipe interface 22 is provided on the outside of the water storage hopper 2. There are two pipe interfaces 22, one of which is located between two adjacent columns 24, and the other pipe interface 22 corresponds to the position of the water supply device 6. The pipe interface 22 provides a channel for the connection of the water supply pipe 81 and the water inlet pipe of the water supply device 6. The sealing sleeve 9 is used to ensure the sealing of the water supply pipe 81 and the water inlet pipe of the water supply device 6 installed in the pipe interface 22. The dust removal net 7 is installed on the inner side of the dust storage hopper 4 and fits with the side of the water supply device 6 close to the bag dust collector 1. The dust removal net 7 can prevent the dust falling into the dust storage hopper 4 from directly contacting the water supply device 6, causing blockage to the water outlet 61 of the water supply device 6, and does not affect the humidification effect of the water supply device 6. The dust removal net 7 is easy to disassemble and assemble, and can be removed from the dust storage hopper 4. When the inside of the hopper 4 is dismantled, the dust in the dust hopper 4 that has been humidified can be removed together, which is convenient for secondary treatment of the dust. The water supply component is composed of a water pump 8 and a water supply pipe 81. The water pump 8 is installed on the outside of the water hopper 2, and the water supply pipe 81 is installed at one end of the water pump 8 and passes through the pipe interface 22 away from the bag dust collector 1. The water pump 8 is electrically connected to the water supply device 6. The water inlet pipe of the water supply device 6 passes through the dust hopper 4 and another pipe interface 22, and is connected to the water pump 8. A sealing sleeve 9 is installed between the inner side of the pipe interface 22 and the water supply pipe 81 and the water inlet pipe of the water supply device 6. The water supply pipe 81 can drain the water in the water hopper 2, and cooperate with the water pump 8 to reintroduce the water into the dust hopper 4 along the water inlet pipe of the water supply device 6, so that the water moves from the dust hopper 4 to the water hopper 2, thereby completing the cycle.

[0031] When the bag dust collector 1 is in use, the dust filtered by the bag dust collector 1 will fall into the dust storage hopper 4 along the discharge port and scatter on the surface of the dust unloading net 7. At this time, the water pump 8 and the water supply equipment 6 are started, and the water pump 8 draws out the water in the water storage hopper 2 through the water supply pipe 81, and then discharges it evenly through the water supply equipment 6, and humidifies the dust on the surface of the dust unloading net 7. The used water will flow to the filter layer 5, be filtered by the filter layer 5, and then pass through the filter hole 41 of the dust storage hopper 4 to re-enter the water storage hopper 2, and then be extracted by the water pump 8 through the water supply pipe 81 to complete the water circulation until the dust removal of the bag dust collector 1 is completed.
