Description

Technical Field

[0001] The present invention relates to the technical field of industrial pollutant treatment, and in particular to an independent water washing treatment device and a treatment method for industrial pollutants. Background Art

[0002] Industrial pollution refers to the pollution of the environment by waste gas, wastewater and solid emissions generated in the industrial production process. As a pollutant in industrial pollution that is extremely easy to spread, industrial waste gas is extremely harmful to human health. Industrial waste gas usually refers to various pollutant gases discharged into the air during the combustion of fuel and production processes in the factory area of ​​the enterprise, including gaseous pollutants such as carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, etc., and usually also carries a large amount of solid fly ash particles such as smoke and industrial dust. In the process of industrial waste gas treatment, enterprises usually focus on the treatment of gaseous pollutants, using reagents, water washing and other methods to absorb them to prevent pollutants from spreading to the external environment.

[0003] For solid particulate matter in exhaust gas, usually only filtering treatment is used to separate the solid waste mixed in the exhaust gas to form solid fly ash powder, which is then simply landfilled and treated as industrial waste. The utilization efficiency of fly ash is low. Moreover, the fly ash of industrial exhaust gas is often mixed with heavy metals, corrosiveness and other pollutants. Direct treatment of fly ash will also cause great harm to the environment.

[0004] In order to reduce the pollution impact of solid waste from waste gas, the waste gas containing solid waste usually needs to be fully washed with water. After the waste gas is washed with water, the solid waste in the waste gas can be purified to a certain extent. Then, the solid waste (i.e. fly ash) required for separation is washed with water independently through independent water washing equipment, thereby reducing the pollution impact of solid waste.

[0005] At present, water washing equipment for treating solid waste in industrial waste gas, such as Figure 1 As shown, an ash inlet 200 is provided on the top of the tank body 1, and a water inlet 100 is provided on the side of the tank body 1. The ash inlet 200 allows industrial waste gas fly ash to enter, and water is injected into the water inlet 100. The motor 4 drives the blades 300 to rotate to mix and fuse the water and fly ash to make pulp. An outlet 12 is provided at the bottom of the tank body 1. After the valve 8 is opened, the pulping product in the tank body 1 is discharged through the pump 9.

[0006] The water inlet 100 generally uses a larger channel for water injection. After the water inlet 100 is injected, the water flows directly to the bottom of the tank body 1. This method mainly relies on the stirring of the blades 300 to merge the fly ash and water, and the efficiency is low. If water is injected by spraying, combined with the stirring of the blades 300, the fusion effect of fly ash and water is better, which can speed up the pulping process. However, the spraying method requires the setting of more water outlets and the size of a single water outlet is relatively small. Since the pulping product is relatively viscous, it is easy to clog the water outlet, resulting in poor subsequent water injection. Summary of the invention

[0007] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide an independent water washing treatment device and treatment method for industrial pollutants. The device adopts spraying water injection pulping, the water outlet is not easily blocked and the efficiency is high.

[0008] To achieve the above object, the technical solution of the present invention is:

[0009] An independent water washing treatment device for industrial pollutants comprises a tank body, a water channel, and a fly ash channel. The tank body is connected with the water channel and the fly ash channel. A valve is connected to the bottom of the tank body, and the valve is connected to a pump. A motor is installed at the upper end of the tank body. The motor comprises a motor shaft. The motor shaft is equipped with blades 1 and 2. The blades 1 and 2 are located in the tank body and can rotate around the motor shaft. The tank body is also equipped with a diverter plate, which is inserted into the tank body. The top position of the diverter plate is lower than the water channel. The diverter plate comprises a diverter plate upper plate, a diverter plate lower plate, and a hollow portion. The hollow portion is located in the diverter plate. Between the upper plate and the lower plate of the diverter plate, the upper plate of the diverter plate is provided with multiple diversion holes and multiple guide holes. The water channel is connected with the hollow part through the guide holes. The lower plate of the diverter plate is provided with multiple diversion holes. A cylinder is also installed on the upper end of the tank body. A sealing plate is connected to the output end of the cylinder. The sealing plate is located above the diverter plate. A plurality of convex columns are provided at the bottom of the sealing plate. The convex columns are at least partially located in the diversion holes. The convex columns can slide up and down along the guide holes and the inner walls of the diverter holes. The lower plate of the diverter plate is also provided with a diversion groove. The sealing plate goes up, and the diversion groove is connected with the diversion hole and the hollow part. The sealing plate goes down, and the convex columns close the diversion hole.

[0010] A plurality of flow splitting holes are arranged radially along the lower plate of the flow splitting plate and are evenly distributed in a circumferential annular array.

[0011] The diverter hole corresponds to the guide hole one by one in the upper and lower sides, and the diverter hole is coaxial with the corresponding guide hole.

[0012] The diverter groove connects two diverter holes adjacent to each other in the radial direction.

[0013] The blade one and the blade two are evenly distributed along the circumference of the motor shaft and are provided with multiple layers up and down. The blade two is located at the bottom layer and the angle between the blade two and the motor shaft is an acute angle.

[0014] The manifold is mounted with a bushing through which the motor shaft passes.

[0015] A pressing plate is installed on the upper end of the bushing, and the bottom surface of the pressing plate is in contact with the top surface of the sealing plate.

[0016] The fly ash channel is located below the diverter plate.

[0017] The bottom of the tank body is conical, and an outlet is arranged at the end of the conical structure at the bottom of the tank body, and the outlet is connected to a valve.

[0018] An independent water washing treatment method for industrial pollutants, comprising the steps of mixing, stirring, and slurry guiding in sequence:

[0019] Mixing: The cylinder drives the sealing plate upward to the limit position, the bottom of the convex column is higher than the bottom of the diversion trough, water flows into the water channel, and fly ash flows into the fly ash channel;

[0020] Stirring: The water channel is closed, the cylinder drives the sealing plate downward to the limit position, the bottom surface of the convex column is flush with or lower than the bottom surface of the diverter plate, and blades one and two rotate to stir.

[0021] Slurry guiding: The valve is opened and the pump draws out the slurry from the tank.

[0022] The beneficial effects of the present invention are:

[0023] 1. The sealing plate and the diverter plate are driven by the cylinder to open the distance between some parts, so that the water channel is connected with the tank body, and the water passing through the diverter plate finally enters the tank body in a spraying manner. The fly ash in the tank body is integrated with the sprayed water flow, and the contact between the fly ash and the water is more complete, which reduces the time required for pulping and has higher efficiency.

[0024] Second: The water inlet and stirring steps are separated and the opening and closing of the diverter hole are controlled by the convex column of the sealing plate. When the diverter hole is closed, the entire hole is filled by the convex column of the sealing plate, and the slurry cannot enter the diverter hole, which can prevent the diverter hole from being blocked by the slurry during stirring and slurrying.

[0025] 3. The center of the guide hole is located near the middle circle of the upper plate of the diversion plate, which can make the amount of water entering the diversion groove more uniform, so that the fly ash is mixed more evenly when spraying water, which is conducive to the next step of mixing and slurrying.

Blade 2 43 is located at the bottom layer and the angle between it and the motor shaft 41 is an acute angle. The downward tilted setting of blade 2 43 allows blade 2 43 to extend into the conical bottom of the tank body 1, which is beneficial to stirring.

[0036] like Figure 2 , 5 As shown, the tank body 1 is also equipped with a diverter plate 3, the fly ash channel 7 is located lower than the diverter plate 3, the diverter plate 3 is inserted into the tank body 1 by interference fit, the diverter plate 3 is a cylindrical structure, the inner wall of the tank body 1 is provided with a boss 13, the boss 13 is a circular ring structure, and the bottom surface of the diverter plate 3 fits the upper end surface of the boss 13.
