Technical Field

[0001] The present application relates to the field of industrial environmental protection technology, and in particular to a sulfur and nitrogen waste gas treatment device. Background Art

[0002] With the improvement of environmental protection requirements and technological progress, waste gas treatment technology in industrial production is also constantly developing and improving. Therefore, industrial enterprises need to pay attention to the latest waste gas treatment technology and emission standards, and take appropriate measures to reduce the generation and emission of waste gas to protect the environment and human health.

[0003] In the prior art, the combustion method is usually used for treatment. The combustion method can efficiently convert harmful substances in sulfur and nitrogen waste gas into harmless substances, thereby achieving the purpose of purifying the waste gas. It has a wide range of applicability. The combustion method is suitable for treating sulfur and nitrogen waste gas of various concentrations and has high flexibility.

[0004] However, new pollutants, such as carbon dioxide and other harmful gases, may be generated during the combustion process, causing certain impacts on the environment. Therefore, a device is needed to treat the secondary pollutants generated after the combustion of sulfur and nitrogen waste gas. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a sulfur and nitrogen waste gas treatment device to solve the problem of needing to treat secondary pollutants generated after combustion.

[0007] By adopting the above technical solution, as the sulfur and nitrogen waste gas enters the waste gas combustion furnace, it will be burned. The burned gas will be transferred to the filter from the top outlet pipe. Since there is a water tank with alkaline absorption liquid connected to the top of the filter, the alkaline absorption liquid will flow into the filter to absorb other harmful substances produced after combustion in the gas, thereby completing the treatment of secondary pollutants.

[0008] Furthermore, one end of the filter is fixedly connected to a water pipe, the other end of the water pipe is fixedly connected to a water tank, and a water pump is provided at the connection between the filter and the water pipe.

[0009] By adopting the above technical solution, the water tank connected to the top of the filter contains alkaline absorption liquid. When the burned gas enters the filter, the alkaline absorption liquid will absorb the harmful substances produced after combustion in the gas. At the same time, the alkaline absorption liquid after absorption will return to the water pipe due to the water pump, allowing it to be poured into the filter from the water tank again.

[0010] Furthermore, a diversion network is provided between the water tank and the filter.

[0011] By adopting the above technical solution, in order to allow the alkaline absorption liquid to fully and evenly absorb the harmful substances produced after combustion in the gas, the diversion network will evenly flow the alkaline absorption liquid to the filter, so that it can fully and evenly absorb the harmful substances.

[0012] Furthermore, a combustion aid is provided on one side of the waste gas combustion furnace and is fixedly connected to the waste gas combustion furnace.

[0013] By adopting the above technical solution, the arrangement of the heater and the combustion aid can accelerate the combustion of the exhaust gas, thereby improving the efficiency of exhaust gas treatment.

[0014] Furthermore, a pull-out collection box is provided at the bottom of the waste gas combustion furnace.

[0015] By adopting the above technical solution, when the sulfur and nitrogen waste gas is burned, some solids may remain in the combustion furnace. In order to increase the service life of the waste gas combustion furnace, a pull-out collection box is opened at the bottom of the waste gas combustion furnace to clean the bottom of the waste gas combustion furnace.

[0016] Furthermore, one end of the filter away from the exhaust gas combustion furnace is connected to the exhaust pipe.

[0017] By adopting the above technical solution, after the exhaust gas is burned and filtered, the purified gas can be directly discharged.

[0018] Furthermore, the exhaust duct is provided with an air suction fan.

[0019] By adopting the above technical solution, the gas after combustion in the equipment can be quickly sucked into the filter through the pipeline for secondary treatment.

[0020] Furthermore, the air inlet pipeline is directly connected to industrial production equipment.

[0021] By adopting the above technical solution, it is possible to prevent waste gas from directly polluting the environment after it is generated.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The exhaust gas combustion furnace is connected to the filter through the exhaust pipe. The filter is connected to a water tank containing alkaline absorption liquid above the filter. After the sulfur-nitrogen exhaust gas is burned, it enters the filter through the exhaust pipe for secondary treatment. The alkaline absorption liquid will absorb the harmful substances in the exhaust gas and turn it into safe gas, which is then directly discharged through the exhaust pipe.

[0024] 2. The water pipe and water pump connecting the filter and the water tank. When the alkaline absorption liquid in the water tank flows from the water tank to the filter, it absorbs the harmful substances in the gas. The water pump will suck the alkaline absorption liquid in the filter back into the water tank for repeated use.

[0025] 3. The bottom of the waste gas combustion furnace is equipped with a pull-out collection box, a heater on one side and a combustion aid on the other side, which can quickly burn the sulfur and nitrogen waste gas to speed up the treatment efficiency. At the same time, since some solids may be produced during the combustion process, they will remain at the bottom of the waste gas combustion furnace, and the pull-out collection box can be used for recycling.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] In this embodiment, refer to Figure 1 , Figure 2A sulfur-nitrogen waste gas treatment device comprises a waste gas combustion furnace 101 and a base 1. The waste gas combustion furnace 101 is fixedly connected to the base 1, and an air inlet pipe 2 is fixedly connected to the waste gas combustion furnace 101. The top of the waste gas combustion furnace 101 is connected to an air outlet pipe 201, and the other end of the air outlet pipe 201 is connected to a filter 302. A water tank 303 is provided above the filter 302 and is connected to the filter 302. Alkaline absorption liquid is placed in the water tank 303. The waste gas is transmitted to the waste gas combustion furnace 101 for combustion along the air inlet pipe 2. After the combustion, the gas enters the filter 302 along the air outlet pipe 201, and the alkaline absorption liquid in the water tank 303 flows into the filter 302, and the harmful substances generated by the combustion in the gas are subjected to secondary treatment, thereby achieving the purpose of treating the harmful substances generated after the combustion treatment of the sulfur-nitrogen waste gas.

[0033] In order to fully absorb the harmful substances in the gas after combustion in the exhaust gas combustion furnace 101, in this embodiment, reference is made to Figure 3 A diversion net 402 is provided at the connection between the filter 302 and the water pipe 301, a water pipe 301 is provided on one side of the filter 302, and the other end of the water pipe 301 is connected to the water tank 303. A water pump 401 is provided at the connection between the filter 302 and the water pipe 301. When the alkaline absorption liquid in the water tank 303 flows into the filter 302, the diversion net 402 will evenly divert the alkaline absorption liquid so that the gas in the filter 302 can fully and evenly contact the alkaline absorption liquid, thereby ensuring that the harmful substances in the post-combustion gas are fully absorbed by the alkaline absorption liquid. At the same time, the alkaline absorption liquid flowing into the filter 302 will return to the water tank 303 along the water pump 401 and the water pipe 301 for repeated use.

[0034] In order to quickly discharge the gas after secondary treatment, in this embodiment, the end of the filter 302 away from the waste gas combustion furnace 101 is connected to the discharge pipe 3, and an air intake fan 4 is arranged on the discharge pipe 3. When the waste gas combustion furnace 101 burns the waste gas, it enters the filter 302 to absorb harmful substances, and the air intake fan 4 quickly discharges the treated gas.

[0035] In order to collect the fixed waste gas generated in the exhaust gas combustion furnace 101, in this embodiment, refer to Figure 4 A pull-out collection box 403 is provided at the bottom of the waste gas combustion furnace 101. The fixed substances that may be generated during the combustion of the waste gas combustion furnace 101 will remain in the furnace. After the combustion is completed, the collection box 403 will be pulled out after the waste gas combustion furnace 101 cools down, and the fixed connections therein will be recycled or reused.

[0036] In the specific implementation process, the exhaust gas inlet pipe 2 of the exhaust gas combustion furnace 101 brings the exhaust gas to be treated to the exhaust gas combustion furnace 101 for combustion. The setting of the combustion aid 102 and the heater can speed up the combustion efficiency. After the combustion is completed, the exhaust gas will enter the filter 302 through the exhaust pipe 201. The alkaline absorption liquid in the connected water tank 303 on the filter 302 will flow into the filter 302, and the gas generated after the combustion will be treated for the second time. The alkaline absorption liquid will remove the harmful substances in the gas. Absorption, at the same time, the filter 302 and the water tank 303 are connected with the water pipe 301, and a water pump 401 is provided at the connection between the filter 302 and the water pipe 301. When the alkaline absorption liquid in the water tank 303 enters the filter 302, the water pump 401 will bring the alkaline absorption liquid back to the water tank 303 along the water pipe 301, and the water in the water tank 303 will flow down again for continuous watering, so that it can fully absorb the harmful substances and alkaline absorption liquid in the gas, thereby achieving the purpose of secondary treatment of the exhaust gas after combustion.

[0037] The diversion net 402 is provided between the water tank 303 and the filter 302. When the alkaline absorption liquid in the water tank 303 flows into the filter 302, the alkaline absorption liquid will be evenly diverted through the diversion net 402 first, so that it can fully contact with the gas passing through the filter 302, thereby fully absorbing the harmful substances in the gas.
