TECHNICAL FIELD

[0001] The utility model belongs to flue gas treatment technical field especially relates to a flue gas treatment equipment for boiler. BACKGROUND

[0002] A boiler is a device that produces steam or hot water, which is composed of a steel container that holds water and a device that burns fire. It uses the heat energy released by burning fuel to heat water, which is converted into high-temperature and high-pressure steam or hot water. These steam or hot water is often used for heating, power generation or driving steam engines, etc.

[0003] During the combustion process, a large amount of flue gas is generated. These flue gases contain particulate matter, sulfur dioxide, nitrogen oxides and other harmful substances. If these harmful substances are directly discharged into the atmosphere, they will pollute the environment, affect air quality, and even cause environmental problems such as acid rain and photochemical smog. Therefore, it is necessary to filter and treat the flue gas generated by the boiler. The existing flue gas treatment equipment often only filters the flue gas through a filter screen during use.

The bottom of the motor 205 is fixedly connected to the top of the box 201. The agitator 206 is located inside the box 201. The top of the agitator 206 penetrates the box 201 and is fixedly connected to the bottom of the output end of the motor 205. The bottom of the box 201 is provided with a collection component 3. The absorption component 1 is used for preliminary filtration of flue gas.The treatment chamber 2 is used for treating the mixture of flue gas and water. To enable further filtration after the water and flue gas mixture is mixed, the collection assembly 3 includes two valves 301, a collection block 302, and a second filter screen 303. The tops of both valves 301 are fixedly connected to the bottom of the chamber 201, and the bottoms of both valves 301 are fixedly connected to the top of the collection block 302. The top of the collection block 302 is fixedly connected to the bottom of the chamber 201. The surface of the second filter screen 303 is inserted into the interior of the collection block 302. By opening the two valves 301, water inside the chamber 201 flows downwards, passing through the two valves 301 and... The impurities enter the interior of the collecting block 302 and pass through the second filter screen 303, where they are filtered again. To ensure stable operation of the second filter screen 303, a plug-in block 4 is fixedly connected to the front of the top of the second filter screen 303. The interior of the plug-in block 4 is plugged into the front of the collecting block 302, and the rear of the plug-in block 4 is fixedly connected to the front of the collecting block 302 via bolts. After the second filter screen 303 drives the plug-in block 4 to plug into the collecting block 302, the collecting block 302 and the plug-in block 4 are fixed together with bolts, thus securing the second filter screen 303 to the collecting block 302.

[0026] The working principle of this utility model:

[0027] When flue gas treatment is required, the flue gas is injected into the inlet pipe 101. The flue gas will continuously pass through the frame 102 and the housing 201, and will be discharged through the connecting pipe 202. During the flow process, the flue gas will first pass through the first filter screen 103, which will initially filter the flue gas. Water is injected into the housing 201 through the water inlet 203. When chemicals are needed according to usage requirements, the cover plate 12 is opened, the chemicals placed in the storage box 11 are taken out and poured into the water inlet 203. After injecting some flue gas, the injection is stopped, and the motor 205 is turned on, so that the output end of the motor 205 drives the agitator 206 to rotate, thereby mixing the flue gas with water. After the operation is completed, the exhaust fan 10 is turned on to make the exhaust fan... 10. Extract the flue gas from inside the housing 201 and discharge it through the exhaust pipe 9. Open the two valves 301 to allow the water inside the housing 201 to flow downwards. The water will carry the impurities in the flue gas downwards and into the collection block 302. The water will pass through the second filter screen 303 and be filtered again. Then the water will be discharged from the drain outlet 6 through the inclined block 5. By removing the bolts fixing the plug block 4 and the collection block 302, the second filter screen 303 can be moved forward and removed from the inside of the collection block 302. By removing the bolts fixing the frame 102 and the first filter screen 103, the first filter screen 103 can be moved upwards and removed from the inside of the frame 102.
