Description

Technical Field

[0001] This utility model relates to the field of SO2 emission technology, specifically to a device for controlling SO2 emission concentration. Background Technology

[0002] SO2 is an acidic and irritating sulfur oxide, and its pollution and health risks make it a key focus of environmental management.

[0003] Most existing desulfurization methods involve proper treatment on the upper side of the limestone slurry mixing tank. When new limestone slurry is mixed with old slurry, the emission concentration cannot be adjusted in time, which poses a risk of exceeding the emission concentration standard. Utility Model Content

[0004] The purpose of this invention is to provide a device for controlling SO2 emission concentration, so as to solve the technical problem that the mixing mode is not adjustable in existing desulfurization methods.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for controlling SO2 emission concentration includes a tank, an air inlet pipe fixedly installed on the side of the tank, a second detection device fixedly installed on the inner side of the air inlet pipe, a control panel fixedly installed on the outer side of the tank, a waste liquid discharge outlet on the bottom surface of the tank, a railing fixedly installed on the inner side of the tank, a spray pipe fixedly installed on the top surface of the railing, a high-pressure nozzle fixedly installed on the bottom surface of the spray pipe, a filter layer fixedly installed on the top surface of the spray pipe, a second railing fixedly installed on the top surface of the filter layer, a second spray pipe fixedly installed on the top surface of the railing, a discharge outlet on the top side of the tank, a filter screen fixedly installed on the top surface of the discharge outlet, a fan fixedly installed on the top surface of the filter screen, and a first detection device fixedly installed on the inner side of the top surface of the filter screen.

[0007] As a preferred embodiment of this utility model, the spray pipe is connected to the interior of the high-pressure nozzle.

[0008] As a preferred embodiment of this utility model, each railing of railing one and railing two is spaced at a fixed distance.

[0009] As a preferred embodiment of this utility model, the filter layer is composed of several activated carbon particles.

[0010] As a preferred embodiment of this utility model, the filter screen is a fiber filter screen.

[0011] As a preferred embodiment of this utility model, the waste liquid outlet is fixedly connected to the drain pipe.

[0012] Compared with the prior art, the device for controlling SO2 emission concentration provided by this utility model has the following beneficial effects:

[0013] This invention connects the inlet pipe to the gas pipe, allowing the waste gas generated during production to enter the tank. Upon entry, the SO2 concentration in the waste gas is monitored by the detection device 2. After entering the tank, desulfurizing agent flows into the inner side of the spray pipe 1 and is sprayed out through the high-pressure nozzle. The high-pressure nozzle sprays out a water mist of desulfurizing agent, which can not only effectively mix and desulfurize the waste gas, but also avoid wasting desulfurizing agent. The railing 1 can increase the contact area between the waste gas and the water mist of desulfurizing agent, so that the desulfurizing agent can be better mixed, improve the desulfurization effect, and reduce the SO2 concentration.

[0014] In this invention, after mixed desulfurization, the gas continues to rise and passes through the filter layer, filtering out larger airborne particles in the exhaust gas. After filtration, a lower concentration of desulfurizing agent in the second spray pipe is used to mix and desulfurize the exhaust gas again. After secondary purification, the fan draws air for discharge, and the detection device monitors the gas again. The detection results of the first and second detection devices are displayed on the control panel. Attached Figure Description

[0022] See Figure 1-2 As shown, an embodiment of this utility model discloses a device for controlling SO2 emission concentration, comprising a tank 1, an air inlet pipe 2 fixedly installed on the side of the tank 1, a detection device 2 15 fixedly installed on the inner side of the air inlet pipe 2, a control panel 3 fixedly installed on the outer side of the tank 1, a waste liquid discharge outlet 4 opened on the bottom surface of the tank 1, a railing 5 fixedly installed on the inner side of the tank 1, a spray pipe 6 fixedly installed on the top surface of the railing 5, a high-pressure nozzle 7 fixedly installed on the bottom surface of the spray pipe 6, a filter layer 8 fixedly installed on the top surface of the spray pipe 8, a railing 9 fixedly installed on the top surface of the filter layer 8, a spray pipe 10 fixedly installed on the top surface of the railing 9, an outlet 11 opened on the top side of the tank 1, a filter screen 12 fixedly installed on the top surface of the outlet 11, a fan 13 fixedly installed on the top surface of the filter screen 12, and a detection device 14 fixedly installed on the inner side of the top surface of the filter screen 12.

[0023] The spray pipe 6 is connected to the high-pressure nozzle 7. The spray pipe 6 can spray out desulfurizing agent for desulfurization, and the high-pressure nozzle 7 can spray out water mist to increase the mixing with the exhaust gas.

[0024] Each railing of railing 5 and railing 9 is spaced at a fixed distance. Railing 5 and railing 9 increase the contact area between the desulfurizing agent and the exhaust gas, allowing the desulfurizing agent to perform desulfurization more effectively.

[0025] The filter layer 8 is composed of several activated carbon particles, which can filter large particles and make the emitted gas cleaner.

[0026] The filter screen 12 is a fiber filter screen, which not only has flowability, but also can intercept small particles and prevent other objects from entering the tank 1.

[0027] Waste liquid outlet 4 is fixedly connected to the drain pipe, and the condensed waste liquid can enter the purification device through the drain pipe.

[0028] In this embodiment of the invention, the inlet pipe 2 is connected to the gas pipe, allowing the waste gas generated during production to enter the tank 1. Upon entry, the SO2 concentration in the waste gas is monitored by the detection device 15. After entering the tank 1, desulfurizing agent flows into the inner side of the spray pipe 6 and is sprayed out through the high-pressure nozzle 7. The high-pressure nozzle 7 sprays a water mist of desulfurizing agent, which not only effectively mixes and desulfurizes the waste gas but also avoids wasting the desulfurizing agent. The railing 5 increases the contact area between the waste gas and the water mist of desulfurizing agent. This process allows the desulfurizing agent to mix better, improving the desulfurization effect and reducing the SO2 concentration. After the desulfurization process, the gas continues to rise and passes through the filter layer 8, filtering out larger airborne particles in the exhaust gas. After filtration, the exhaust gas is mixed and desulfurized again in the spray pipe 10 with a lower concentration of desulfurizing agent. After secondary purification, the fan 13 draws air for discharge, and the detection device 14 monitors it again. The detection results of the detection device 14 and the detection device 2 15 are displayed on the control panel 3.

[0029] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention.
