Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to a waste gas treatment system. Background Technique

[0002] Waste gas treatment is also known as waste gas purification. Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before external discharge to meet the national standards for external discharge of waste gas. Generally, waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment, air sterilization and disinfection purification, etc. Waste gas generally has the characteristics of being flammable, explosive, toxic, harmful, insoluble in water, soluble in organic solvents, and difficult to treat. Organic waste gas treatment refers to the treatment of organic waste gas generated in the industrial production process by adsorption, filtration, and purification. The commonly used waste gas treatment device is an adsorption-desorption catalytic combustion device, that is, a fixed-bed adsorption and desorption device is used to adsorb the waste gas. After the adsorption medium is saturated, it is desorbed at high temperature, and then the waste gas generated by desorption is introduced into the catalytic combustion furnace for catalytic combustion. The catalyst in the catalytic combustion furnace can lower the ignition temperature of volatile organic compounds and improve the combustion efficiency.

[0003] The prior art (publication number: CN 219518245U) discloses a waste gas treatment system, which includes a filtration box and a purification box connected in communication. An inlet water component is arranged on the filtration box, a spraying component and a recycling component communicated with the inlet water component are arranged in the filtration box, an injection gas pipe is installed on the purification box, and a gas stirring device is installed in the purification box; an inlet gas pipe a is connected to the left side of the filtration box, an exhaust pipe is installed on the right side of the purification box, and a sewage discharge pipe is installed at the bottom of the filtration box;

[0004] Although the above patent sprays the waste gas injected into the filtration box through a nozzle to increase the contact area between the waste gas and water and drip the particulate impurities in the waste gas to the bottom of the filtration box, there are the following drawbacks. The waste gas moves to the right through the filtration box, and the filtration box cannot extend the residence time of the waste gas. If the residence time of the waste gas in the filtration box is not long enough, the filtration medium in the filtration box may not be able to fully remove the pollutants in the waste gas, which will reduce the filtration efficiency and make the discharged waste gas still contain harmful substances, and further improvement is needed. For this reason, we propose a waste gas treatment system. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a waste gas treatment system, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An exhaust gas treatment system includes a tank body. A drain valve pipe is inserted and connected to the middle of the lower end of the tank body. An exhaust pipe is inserted and connected to the upper end of the tank body. A horizontal plate is installed on the left part of the outer surface of the tank body. A waste gas pipe and a liquid inlet valve pipe are inserted and connected to the right part of the outer surface of the tank body from top to bottom. A delaying component is installed in the middle of the inner cylindrical surface of the tank body. A pump body is installed on the upper end of the horizontal plate.

[0008] Preferably, a heating pipe is installed on the lower inner wall of the tank body. The heating pipe extends to the outer surface of the tank body. The heating pipe is spiral.

[0009] Preferably, the delaying component is a spiral blade. The spiral blade is arranged in the middle of the inner cylindrical surface of the tank body.

[0010] Preferably, an activated carbon filter screen, a demister and a baffle are sequentially arranged on the upper part of the inner cylindrical surface of the tank body from top to bottom.

[0011] Preferably, the liquid suction end of the pump body extends into the tank body and extends to the lower wall of the tank body. The liquid discharge end of the pump body extends into the tank body and is communicated with the lower end of the hollow pipe through the baffle.

[0012] Preferably, a rectangular groove is opened in the upper right part of the baffle. The upper end of the vertical plate extends into the rectangular groove.

[0013] Preferably, the upper end of the hollow pipe is fixedly connected to the lower end of the baffle.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. By setting the delaying component, the residence time of the exhaust gas in the tank body can be increased. During use, the exhaust gas enters the tank body through the waste gas pipe. The spiral blade makes the exhaust gas spiral upward, and then the atomizing nozzles perform spraying, avoiding the vertical upward movement of the exhaust gas, increasing the travel of the exhaust gas through the rectangular groove, thereby increasing the residence time of the exhaust gas, increasing the contact time between the liquid medicine and the exhaust gas, improving the filtration efficiency, facilitating the thorough removal of harmful substances, and making the discharged exhaust gas cleaner;

[0016] 2. By setting the heating pipe, the liquid medicine can be heated. During purification, the power supply of the heating pipe is turned on, and the heating pipe heats the liquid medicine. Heating the liquid medicine can increase the thermal motion of molecules, improve the collision frequency between molecules, and thus promote the reaction rate of the exhaust gas and the liquid medicine for neutralization, which helps to neutralize harmful substances faster and improve the treatment efficiency.

[0025] Such as Figures 1 - 4As shown in the figure, an exhaust gas treatment system includes a tank body 1. A drain valve pipe 8 is inserted and connected to the middle of the lower end of the tank body 1. An exhaust pipe 2 is inserted and connected to the upper end of the tank body 1. A horizontal plate 4 is installed on the left part of the outer surface of the tank body 1. An exhaust gas pipe 5, a liquid inlet valve pipe 6 are inserted and connected from top to bottom on the right part of the outer surface of the tank body 1. A delay component 12 is installed in the middle of the inner cylindrical surface of the tank body 1. A pump body 3 is installed on the upper end of the horizontal plate 4.

[0026] During use, neutralizing waste gas medicine water is injected into the tank body 1 through the liquid inlet valve pipe 6. The waste gas is transported into the tank body 1 through the exhaust gas pipe 5. The waste gas spirally ascends through the delay component 12. At the same time, the pump body 3 transports the medicine water into the delay component 12. The delay component 12 sprays out the medicine water to neutralize the waste gas. The spiral ascent increases the travel of the waste gas through the rectangular groove 111, thereby increasing the residence time of the waste gas, increasing the contact time between the medicine water and the waste gas, thus improving the filtration efficiency, facilitating the thorough removal of harmful substances, and making the discharged waste gas cleaner.

[0027] A heating pipe 7 is installed on the lower inner wall of the tank body 1. The heating pipe 7 extends to the outer surface of the tank body 1. The heating pipe 7 is spiral-shaped, and the spiral shape is used to increase the heating area. Before the pump body 3 sprays the medicine water, the power supply of the heating pipe 7 is turned on, and the heating pipe 7 heats the medicine water. Heating the medicine water can increase the thermal motion of molecules, improve the collision frequency between molecules, thereby promoting the rate of the neutralization reaction between the waste gas and the medicine water, which helps to neutralize harmful substances faster and improve the treatment efficiency.

[0028] The delay component 12 is used to increase the residence time of the waste gas in the tank body 1. The delay component 12 has spiral blades 121. The spiral blades 121 are arranged in the middle of the inner cylindrical surface of the tank body 1. A hollow pipe 122 is arranged inside the spiral blades 121. A vertical plate 124 is installed on the upper part of the spiral blades 121. A number of atomizing nozzles 123 are inserted and connected to the outer surface of the hollow pipe 122. The atomizing nozzles 123 are distributed in a spiral shape. The liquid suction end of the pump body 3 extends into the tank body 1 and extends to the lower wall of the tank body 1. The liquid discharge end of the pump body 3 extends into the tank body 1 and is communicated with the lower end of the baffle 11 and the hollow pipe 122. During use, the spiral blades 121 make the waste gas spiral upward. The pump body 3 transports the medicine water into the hollow pipe 122, and then the atomizing nozzles 123 perform spray neutralization to prevent the waste gas from rising vertically.

[0029] Further, an activated carbon filter net 10, a demister 9 and a baffle 11 are sequentially arranged on the upper part of the inner cylindrical surface of the tank body 1 from top to bottom. A rectangular groove 111 is formed in the upper right part of the upper end of the baffle 11. The baffle 11 is used for introducing waste gas into the rectangular groove 111. The upper end of the vertical plate 124 extends into the rectangular groove 111. When the waste gas is neutralized by the medicinal liquid, it enters the upper part of the tank body 1 through the rectangular groove 111. The demister 9 removes the mist in the waste gas, and then the activated carbon filter net 10 filters the waste gas, and finally it is discharged through the exhaust pipe 2.

[0030] To improve the stability of the hollow tube 122, the upper end of the hollow tube 122 is fixedly connected to the lower end of the baffle 11.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
