Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a powder spraying and pulse dust collector system. Background Technique

[0002] The pulse dust collector system is a high-efficiency industrial dust treatment equipment integrating filtration separation and pulse jet cleaning technology. Through the synergistic effect of physical interception and intelligent cleaning, the purification of dust-containing gas is realized. Its core function is to efficiently separate dust particles from gas, and the emission concentration can be stably lower than 10mg / Nm³. It is widely used in industrial scenarios with high temperature, high humidity and high dust load.

[0003] As an efficient dust removal equipment, when dealing with oily dust, the pulse dust collector needs to spray slaked lime on the cloth bag, which is commonly known as powder attachment. When the oily dust enters the cloth bag, it condenses with the slaked lime into small oil beads, and the pulse valve is used for dust cleaning. In the tire rubber industry, the sulfur vulcanization process and rubber mixing process generate dust containing oiliness, and the oily dust has the characteristics of adhesiveness and difficulty in separation.

[0004] At present, domestic pulse dust collectors use waste gas for powder attachment during secondary powder attachment (powder attachment without stopping the machine). When attaching powder with oily waste gas, the dust and slaked lime will stick to the cloth bag together. When the oily gas blocks the cloth bag, the cloth bag cannot filter dust. At this time, the blocked cloth bag needs to be replaced, and workers need to spend a lot of time checking the cloth bags in each chamber one by one, which brings inconvenience to use. Therefore, there is an urgent need for a powder spraying and pulse dust collector system to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a powder spraying and pulse dust collector system to solve the problems in the above background technique that attaching powder with oily waste gas will cause dust and slaked lime to stick to the cloth bag together, the oily gas blocks the cloth bag, the cloth bag cannot filter dust, and the blocked cloth bag needs to be replaced after being blocked.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A powder spraying and pulse dust collector system includes a dust collector box body.

[0019] Please refer to Figure 1-2 , a powder spraying and pulse dust collector system, including a dust collector box body 20. A chamber is arranged inside the dust collector box body 20, and the chambers are connected by a compartment partition 12. A pulse valve 14 is arranged above the inside of the dust collector box body 20. An exhaust gas inlet 11 is opened on the left outer surface of the dust collector box body 20. An exhaust gas outlet 15 is opened on the right side of the dust collector box body 20, and the exhaust gas outlet 15 is connected to a dust collector fan 16 through an exhaust gas outlet pipeline. A No. 1 exhaust gas valve 10, a No. 2 exhaust gas valve 9, and a No. 3 exhaust gas valve 8 are sequentially arranged in the middle of the inside of the dust collector box body 20. A No. 1 fresh air valve 4, a No. 2 fresh air valve 5, and a No. 3 fresh air valve 6 are correspondingly installed on the lower side of the No. 1 exhaust gas valve 10, the No. 2 exhaust gas valve 9, and the No. 3 exhaust gas valve 8. Filter modules 7 are installed directly below the No. 1 fresh air valve 4, the No. 2 fresh air valve 5, and the No. 3 fresh air valve 6, and the right side of the filter module 7 is connected to the powder adhering pipeline 2. A dust cleaning mechanism 1 is arranged below the inside of the dust collector box body 20, and the left side of the dust cleaning mechanism 1 is connected to a powder spraying device 3. A No. 1 lifting valve 17, a No. 2 lifting valve 18, and a No. 3 lifting valve 19 are respectively arranged on the powder spraying and pulse dust collector system.

[0020] Among them, the powder spraying device 3 is connected to the filter module 7 through the powder adhering pipeline 2.

[0021] Among them, a filter mechanism 13 is installed in the middle chamber inside the dust collector box body 20.

[0022] Among them, the number of the compartment partitions 12 is three groups, and the compartment partitions 12 are in an inclined plate or baffle structure.

[0023] Among them, a motor and a speed reducer are arranged in the dust cleaning mechanism 1, and the dust cleaning mechanism 1 moves after the motor drives the speed reducer to rotate.

[0024] A powder spraying and pulse dust collector system of the present utility model is composed of a powder spraying device 3, a dust collector box body 20, a filtering mechanism 13, a pulse valve 14, a dust cleaning mechanism 1, an exhaust gas valve, a fresh air valve, a lifting valve, an attached powder pipeline 2, and a dust collector fan 16.

[0025] During operation, first close the compartment partition 12 of the bin. There is a compartment partition 12 inside the dust collector. When performing secondary attached powder (attached powder without stopping the machine), close the No. 1 exhaust gas valve 10. At this time, the No. 2 exhaust gas valve 9 and the No. 3 exhaust gas valve 8 are in the normally open state. Then open the corresponding No. 1 fresh air valve 4. A filtering module 7 is arranged at each fresh air valve port. The filtering module 7 will filter larger particulate matters. Then open the No. 1 lifting valve 17. At this time, start the powder spraying device 3 and convey slaked lime into the dust collector box body 20. The inside of the dust collector box body 20 must be in negative pressure. The dust collector fan 16 starts to work. The slaked lime entering the dust collector will be sucked by the dust collector fan 16 into the inside of a single bin, so as to attach powder to the cloth bag. If the No. 2 exhaust gas valve 9 is closed, the No. 1 exhaust gas valve 10 and the No. 3 exhaust gas valve 8 are in the normally open state. Then open the corresponding No. 2 fresh air valve 5. Then open the No. 2 lifting valve 18. Then cycle in turn. Finally, start the powder spraying device 3 and convey slaked lime into the dust collector box body 20. By arranging a compartment partition 12 inside the dust collector and using fresh air for attached powder, it is avoided that the oil-containing exhaust gas blocks the cloth bag, thereby improving the service life of the cloth bag, reducing the frequency of replacing the cloth bag, saving material and labor costs, and improving the working efficiency of the equipment.
