Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a gas distribution structure for high-concentration dust. Background Technique

[0002] When some enterprises produce related products, they will generate a large amount of waste gas doped with finished product particle dust and organic gas. If these waste gases are directly discharged without treatment, on the one hand, it will cause environmental pollution, and on the other hand, since the discharged waste gas contains finished product particles, it will cause waste of energy and increase the energy consumption of products. At present, the devices for dust recovery use multiple methods such as cyclone centrifugation, pulse dust cleaning, bag filtration, and vacuum suction for dust removal. These methods have the advantages of comprehensive dust removal, hermetic recovery of dust waste, and no environmental pollution.

[0003] The patent with the authorization announcement number CN207838519U discloses a large bag dust collector diversion and uniform distribution device, including an air inlet pipe, an air outlet pipe, and a bag dust collector body. It also includes an air inlet diversion mechanism. The air inlet diversion mechanism includes an air intake passage arranged between the air inlet pipe and the air inlet. In the air intake passage, a first flow equalizing plate, a second diversion plate, and a third diversion plate are arranged vertically and parallel to each other from left to right in sequence. The first flow equalizing plate, the second diversion plate, and the third diversion plate are all flat plates arranged parallel to each other and vertically. Round holes are opened on the flat plates. The second diversion plate and the third diversion plate are also provided with diversion vanes. High-concentration dust gas passes through the first flow equalizing plate and then flows to the second diversion plate and the third diversion plate. The structure is complex and the cost is high. The retention effect of large particles is poor when high-concentration dust gas passes through. Moreover, there is no dust cleaning and purging device. After long-term use, dust accumulation will affect the air flow passing effect and needs to be improved. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects, provide a gas distribution structure for high-concentration dust, make the air flow decelerate and then blow out evenly, be able to retain large particles in high-concentration dust gas, and also be able to purge the diversion plate to reduce the influence of dust accumulation on the passing effect, and is convenient to use, and can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A gas distribution structure for high-concentration dust, including a chassis. The chassis is provided with an air inlet. Inside the chassis, a plurality of diversion plates parallel to each other and arranged at equal intervals are provided corresponding to the air inlet. The diversion plates are in an L shape with the right-angle end facing upwards. One side plate of the diversion plate is inclined and corresponds to the air inlet. An air flow channel is formed between two adjacent diversion plates.

[0006] Preferably, a plurality of support angle irons are correspondingly provided on two opposite side walls of the chassis. The support angle irons are connected to the diversion plates through bolt and nut groups. Both ends of the diversion plates are attached to two opposite side walls of the chassis.

[0007] Preferably, a purging mechanism is further provided inside the chassis corresponding to the rear of the flow dividing plate. The purging mechanism includes a vertically arranged blowing pipe that penetrates the chassis. The blowing pipe is communicated with a plurality of blowing branch pipes parallel to the flow dividing plate, and a plurality of nozzles for purging the air flow channels are evenly arranged on the blowing branch pipes.

[0008] Preferably, a dust discharge port is further communicated with the lower part of the chassis. The dust discharge port is located in front of the flow dividing plate, and a gate valve is provided at the dust discharge port.

[0009] Preferably, the included angle between the side plate of the flow dividing plate opposite to the air inlet and the horizontal direction is 30° - 60°.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: By arranging a plurality of flow dividing plates at equal intervals inside the chassis, a plurality of air flow channels are formed. When the high-concentration dust gas blows towards the flow dividing plate and collides with it, the large particles in the gas fall, and the air flow continues to flow in the air flow channel. The air flow decelerates and then blows out evenly, which can achieve retaining large particles in the high-concentration dust gas and reducing the air flow velocity. In addition, a purging mechanism is provided, which can purge the flow dividing plate and reduce the influence of dust accumulation on the passing effect, and is convenient to use.

[0016] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model. In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or positional relationship, it is only corresponding to the drawings of the present application for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation.

[0017] Please refer to Figures 1-4, the present utility model provides the following technical solutions:

[0018] Embodiment 1: A gas distribution structure for high-concentration dust, including a chassis 1. The chassis 1 is provided with an air inlet 2. Inside the chassis 1, corresponding to the air inlet 2, there are a plurality of shunt plates 5 arranged parallel to each other and at equal intervals. The shunt plates 5 are L-shaped with the right-angle end facing upwards. One side plate of the shunt plate 5 is inclined and corresponds to the air inlet 2. The side plate of the shunt plate 5 opposite to the air inlet 2 forms an angle of 30° - 60° with the horizontal direction. An air flow channel is formed between two adjacent shunt plates 5, and the air flow channel is also L-shaped, that is, the side plate of the shunt plate 5 is inclined and faces the air inlet 2. The high-concentration dust gas blows towards this side plate, and the large particles in the concentration dust gas will fall along this side plate due to the air flow collision. The air flow continues to flow in the air flow channel. Since the air flow channel is L-shaped, the air flow will form a vortex in the right-angle area of the shunt plate 5, thereby decelerating the air flow, and then the air flow is evenly blown out, so that the air flow can be evenly blown out after deceleration, and at the same time, the large particles in the high-concentration dust gas can be retained.

[0019] Embodiment 2: Different from Embodiment 1, a plurality of support angle irons 8 are correspondingly arranged on two opposite side walls of the chassis 1. The support angle irons 8 are connected to the shunt plates 5 through bolt-nut groups 7. The two ends of the shunt plates 5 are attached to the two opposite side walls of the chassis 1. The shunt plates 5 are connected to the support angle irons 8 by means of threaded nut groups 7, and the detachable connection method is adopted, which is convenient for installation and disassembly.

[0020] Embodiment 3: Different from Embodiment 1, a purging mechanism is further provided inside the chassis 1 corresponding to the rear of the shunt plates 5. The purging mechanism includes a vertically arranged spray pipe 4. The spray pipe 4 penetrates the chassis 1. The spray pipe 4 is communicated with a plurality of spray branches 9 parallel to the shunt plates 5. A plurality of nozzles 6 for purging the air flow channel are evenly arranged on the spray branches 9; after long-term use, dust will accumulate on the shunt plates 5, thus affecting the air flow passing effect. To solve the problem of dust accumulation, purging is carried out by setting a purging mechanism. When purging is required, the air inlet 2 is closed, and the spray pipe 4 is externally connected to a high-pressure air source. The high-pressure air source blows high-pressure gas into the air flow channel through the spray branches 9 and the nozzles 6 to purge the shunt plates 5;

[0021] In addition, a dust discharge port 3 is further communicated with the lower part of the chassis 1. The dust discharge port 3 is located in front of the shunt plates 5. A gate valve is provided at the dust discharge port 3. After the high-concentration dust gas is retained, it falls towards the dust discharge port 3, and the dust is regularly discharged through the dust discharge port 3.

[0022] The parts not detailed in this utility model are prior arts. For those skilled in the art, it is obvious that this utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
