Description

Technical Field

[0001] This invention relates to the field of waste gas purification, and more particularly to a chemical waste gas purification system. Background Technology

[0002] With the rapid development of the chemical industry, the problem of industrial waste gas emissions has become increasingly serious. Waste gas pollution has become one of the most pressing problems to be solved in the field of environmental protection. These waste gases pose a great threat to air quality, ecological environment and human health.

[0003] A spray tower is a common waste gas treatment device. The basic working principle of a spray tower is to use hot water to contact the waste gas in a counter-current manner, and to use the properties of liquid such as adsorption, dissolution and chemical reaction with waste gas to remove harmful substances in the waste gas. Then, a catalyst is used to further treat and purify the gas.

[0004] When using an exhaust gas purification system to purify gases, the catalyst and exhaust gas usually require a long time to complete the reaction. This is due to the limited contact area and reaction time between the gas and the catalyst, resulting in low reaction efficiency between the catalyst and the exhaust gas, which limits the overall efficiency of exhaust gas treatment.

[0005] This is especially noticeable when the volume of exhaust gas is large. Furthermore, the spray water in the spray tower, after adsorbing pollutants in the exhaust gas, is usually directly discharged and discarded without recycling the resources, resulting in a huge waste of water resources. At the same time, a large amount of heat is generated in the system during the exhaust gas treatment process. However, existing systems often fail to fully recover this heat, resulting in energy waste and increased system operating costs. Summary of the Invention

[0006] This invention provides a chemical waste gas purification system. By increasing the collision frequency between gas molecules and active sites on the catalyst surface, this invention accelerates the reaction rate and further improves gas treatment efficiency. When using this gas purification system, the sprayed water can be recycled multiple times, which helps to reduce water waste. At the same time, the heat generated by the treated gas is recovered and utilized, reducing the demand for external energy and lowering overall energy consumption.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a chemical waste gas purification system, the system comprising: Gas processing tanks and spray towers; Two fixing plates are fixedly installed on the inner wall of the gas treatment tank, and a support ring is fixedly installed on one side of the two fixing plates opposite to each other. The two fixing plates support the support ring, so that the transmission rod is installed inside the gas treatment tank. The transmission rod is mounted on the inner wall of the support ring via a bearing, and multiple stirring plates are fixedly mounted on the outer surface of the transmission rod. The transmission rod can rotate via the bearing, driving the multiple stirring plates to rotate, stirring the gas and catalyst inside the gas treatment tank, so that the two are fully mixed together, improving the reaction rate of the two, and further improving the gas treatment efficiency. Multiple arc-shaped scrapers are fixedly disposed on one side of multiple stirring plates, and the multiple arc-shaped scrapers are movably disposed on the inner wall of the gas treatment tank. When the multiple stirring plates rotate, they drive the multiple arc-shaped scrapers to rotate. The multiple arc-shaped scrapers are in close contact with the inner wall of the gas treatment tank, scraping the reactants or catalysts on the inner wall of the gas treatment tank, preventing the reactants or catalysts from sticking to the inner wall of the gas treatment tank under the action of heat. An exhaust pipe is fixedly installed on one side of the gas treatment tank, and a fan is installed at one end of the exhaust pipe. When the external power switch of the fan is turned on, the input end of the fan generates suction, which draws the gas treated inside the gas treatment tank into the exhaust pipe.

[0008] As a further improvement of the present invention: an exhaust pipe is installed at the output end of the blower, multiple heating tubes are installed on the outer surface of the gas treatment tank, an isolation plate is fixedly sleeved on the outer surface of the gas treatment tank, and a turbine blade is fixedly installed at one end of the transmission rod. The treated gas is discharged through the exhaust pipe. Because the gas flows rapidly under the guidance of the blower, and the turbine blade is located inside the exhaust pipe, the gas drives the turbine blade to rotate when it passes through the turbine blade, and the rotation of the turbine blade drives the transmission rod to rotate.

[0009] As a further improvement of the present invention: a storage tank is fixedly installed at the bottom of the spray tower, and a conveying pipe is installed on the outer surface of the storage tank. The storage tank is used to store wastewater and hot water, and the hot water inside the storage tank is discharged through the conveying pipe.

[0010] As a further improvement of the present invention: a hot water pump is installed at one end of the conveying pipe, and a spray pipe is installed at the output end of the hot water pump. When the external power switch of the hot water pump is turned on, the hot water inside the storage tank is further discharged into the spray pipe through the conveying pipe under the action of the hot water pump.

[0011] As a further improvement to the present invention: the spray pipe is disposed on the inner wall of the spray tower, an air inlet pipe is installed on one side of the spray tower, and a gas guide pipe is installed on the side of the spray tower away from the storage tank. One end of the gas guide pipe is installed on one side of the gas treatment tank, and a vertical plate is fixedly installed on the inner wall of the storage tank. The spray pipe sprays hot water into the interior of the spray tower, where the hot water and the gas entering the spray tower come into countercurrent contact and fully react with the pollutants in the gas, transforming them into liquid or sediment. The waste gas to be purified is discharged into the interior of the spray tower through the air inlet pipe; the gas treated by the spray tower is discharged into the interior of the gas treatment tank through the gas guide pipe.

[0012] As a further improvement of the present invention: a first sewage pipe is installed on the outer surface of the storage box, a sewage pump is installed at one end of the first sewage pipe, a second sewage pipe is provided at the output end of the sewage pump, and a sewage treatment tank is provided at one end of the second sewage pipe. When the external power switch of the sewage pump is turned on, the sewage inside the storage box is discharged into the second sewage pipe through the first sewage pipe under the action of the sewage pump, and further treated by the sewage treatment tank. The sewage treatment tank removes pollutants from the water by adding chemical agents to react with substances in the water. This is the prior art and will not be described in detail here.

[0013] As a further improvement of the present invention: a heat insulation pipe is fixedly installed on the outer surface of the gas treatment tank, and a first connecting pipe is installed on the outer surface of the heat insulation pipe. When the gas treatment tank treats the gas inside, multiple heating pipes are in the open state, and the water discharged into the heat insulation pipe is heated at the same time. The heated water inside the heat insulation pipe is then discharged into the second connecting pipe through the first connecting pipe.

[0014] As a further improvement of the present invention: a delivery pump is fixedly installed at one end of the first connecting pipe, and a second connecting pipe is installed at the output end of the delivery pump. When the external power switch of the delivery pump is turned on, the input end of the delivery pump generates suction, which discharges the water heated inside the heat insulation pipe into the interior of the second connecting pipe.

[0015] As a further improvement of the present invention: one end of the second connecting pipe is fixedly disposed on one side of the storage box, and a hot water chamber is disposed on the inner wall of the storage box for storing the heated hot water.

[0016] As a further improvement of the present invention: a drain pipe is installed at the bottom of the sewage treatment tank, one end of which is fixedly set on the outer surface of the heat insulation pipe, and the treated sewage is discharged into the interior of the heat insulation pipe through the drain pipe.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, the gas treated by the spray tower is discharged into the gas treatment tank through a gas guide pipe. The gas treatment tank contains a catalyst, which reacts with harmful components in the gas to further treat it. The external power switches of multiple heating elements are turned on, heating the interior of the gas treatment tank to accelerate the reaction between the waste gas and the catalyst. At the same time, the external power switch of the blower is turned on, generating suction at the blower's input end, drawing the treated gas from the gas treatment tank into the exhaust pipe, where it is further discharged through the exhaust stack. Because the gas flows rapidly under the action of the fan, and the turbine blades are located inside the exhaust pipe, the gas passing through the turbine blades drives the turbine blades to rotate. The rotation of the turbine blades drives the transmission rod to rotate, which in turn causes multiple stirring plates to rotate. The rotation of the stirring plates agitates the gas and catalyst inside the gas treatment tank, allowing them to fully mix together and increasing the reaction rate, thereby improving the gas treatment efficiency. The rotation of the stirring plates also drives multiple arc-shaped scrapers to rotate. These scrapers are in close contact with the inner wall of the gas treatment tank, scraping the catalyst on the inner wall to prevent reactants or catalyst from adhering to the inner wall of the gas treatment tank under the action of heat. This increases the collision frequency between gas molecules and the active sites on the catalyst surface when using the gas purification system, which accelerates the reaction rate and further increases the gas treatment efficiency.

[0018] 2. In this invention, when purifying chemical waste gas, the waste gas to be purified is discharged into the interior of the spray tower through the inlet pipe. At this time, the external power switch of the hot water pump is turned on, and the hot water inside the storage tank is discharged into the spray pipe through the delivery pipe under the action of the hot water pump. The hot water is further sprayed to make full contact and reaction with the gaseous pollutants inside the spray tower, converting the pollutants into liquid or sediment. The vertical plate divides the interior of the storage tank into two parts. There is a semi-circular opening on the upper side of the vertical plate, and sewage will be discharged into the interior of the storage tank. The external power switch of the sewage pump is turned on, and the sewage inside the storage tank is discharged into the interior of the second sewage pipe through the first sewage pipe under the action of the sewage pump. The sewage is further treated through the sewage treatment tank and then discharged into the interior of the storage tank. Thus, when using the gas purification system, the spray water can be reused multiple times, which helps to reduce the waste of water resources.

[0019] 3. In this invention, when the gas treatment tank processes the gas inside, multiple heating tubes are in the open state, simultaneously heating the water discharged into the insulated pipe. The external power switch of the delivery pump is turned on, generating suction at the pump's input end. This suction draws the heated water from inside the insulated pipe through a first connecting pipe to a second connecting pipe, and further into a storage tank. The hot water in the storage tank then returns to the tank and, through the delivery pipes, further processes the waste gas inside the spray tower. This allows the purification system to recover and reuse heat from the treated gas, reducing the need for external energy and lowering overall energy consumption. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] During operation, the gas treated by the spray tower 3 is discharged into the gas treatment tank 1 through the gas guide pipe 311. The gas treatment tank 1 contains a catalyst, which further treats the gas, causing a reaction between the catalyst and the gas. Turning on the external power switch of the multiple heating tubes 209 energizes the gas treatment tank 1, accelerating the reaction between the waste gas and the catalyst. Turning on the external power switch of the blower 201 generates suction at its input, drawing the treated gas from the gas treatment tank 1 into the exhaust pipe 2, where it is further discharged through the exhaust stack 202. Turbine blades 208 are located inside exhaust pipe 2. When gas passes through turbine blades 208, it flows rapidly under the guidance of fan 201, causing turbine blades 208 to rotate. Two fixed plates 203 support support ring 204. Transmission rod 205 is installed inside gas treatment tank 1 via 204. Transmission rod 205 can rotate via bearings. When turbine blades 208 rotate, they drive transmission rod 205 to rotate, further causing multiple stirring plates 206 to rotate. The rotation of multiple stirring plates 206 stirs the gas and catalyst inside gas treatment tank 1, allowing them to fully mix together, increasing their reaction rate, and further improving gas treatment efficiency.

The spray pipe 304 sprays hot water into the interior of the spray tower 3. The hot water and the gas inside the spray tower 3 come into countercurrent contact, reacting with the pollutants in the waste gas and converting them into liquid or sediment. The waste gas to be purified is discharged into the interior of the spray tower 3 through the air inlet pipe 305, and the gas treated by the spray tower 3 is discharged into the interior of the gas treatment tank 1 through the gas guide pipe 311.

[0037] Please see Figures 1 to 9 In one embodiment, a first sewage pipe 307 is installed on the outer surface of the storage box 301. A sewage pump 308 is installed at one end of the first sewage pipe 307. A second sewage pipe 309 is provided at the output end of the sewage pump 308. A sewage treatment tank 310 is provided at one end of the second sewage pipe 309. When the external power switch of the sewage pump 308 is turned on, the sewage inside the storage box 301 is discharged into the second sewage pipe 309 through the first sewage pipe 307 under the action of the sewage pump 308, and further treated by the sewage treatment tank 310.

[0038] It should be noted that the sewage treatment tank 310 treats sewage by adding chemical agents to react with substances in the water to remove pollutants. This is existing technology and will not be described in detail here.

[0039] Please see Figures 1 to 9 In one embodiment, a heat insulation pipe 4 is fixedly provided on the outer surface of the gas treatment tank 1, and a first connecting pipe 402 is installed on the outer surface of the heat insulation pipe 4. When the gas treatment tank 1 treats the gas inside, multiple heating pipes 209 are in the open state, and the water discharged into the heat insulation pipe 4 is heated at the same time. The heated water inside the heat insulation pipe 4 is discharged into the second connecting pipe 404 through the first connecting pipe 402 via 403.

[0040] Please see Figures 1 to 9 In one embodiment, a delivery pump 403 is fixedly installed at one end of the first connecting pipe 402, and a second connecting pipe 404 is installed at the output end of the delivery pump 403. When the external power switch of the delivery pump 403 is turned on, the input end of the delivery pump 403 generates suction, which discharges the water heated inside the heat insulation pipe 4 into the second connecting pipe 404.

[0041] Please see Figures 1 to 9In one embodiment, one end of the second connecting pipe 404 is fixedly disposed on one side of the storage tank 301, and a hot water chamber 405 is disposed on the inner wall of the storage tank 301 for storing heated hot water.

[0042] Please see Figures 1 to 9 In one embodiment, a drain pipe 401 is installed at the bottom of the sewage treatment tank 310. One end of the drain pipe 401 is fixedly disposed on the outer surface of the heat insulation pipe 4, and the treated sewage is discharged into the interior of the heat insulation pipe 4 through the drain pipe 401.

[0043] System exhaust gas treatment process and working principle: When purifying chemical exhaust gas, the exhaust gas to be purified is discharged into the interior of the spray tower 3 through the inlet pipe 305. At this time, the external power switch of the hot water pump 303 is turned on, and the hot water in the storage tank 301 is discharged into the spray pipe 304 through the delivery pipe 302 under the action of the hot water pump 303. The hot water is further sprayed so that it comes into contact with the gaseous pollutants entering the spray tower 3 and reacts, converting some pollutants into liquid or sediment. The vertical plate 306 divides the interior of the storage tank 301 into two parts. The upper side of the vertical plate 306 has a semi-circular opening, through which the wastewater after the gas phase reaction is discharged into the interior of the storage tank 301. The gas treated by the spray tank 3 is discharged into the gas treatment tank 1 through the gas guide pipe 311. The gas treatment tank 1 contains a catalyst, which further treats the gas, allowing the catalyst and gaseous pollutants to react and purify the gas. The external power switch of multiple heating tubes 209 is turned on, and the multiple heating tubes 209 are powered on to heat the inside of the gas treatment tank 1, accelerating the reaction rate between the harmful components in the exhaust gas and the catalyst. At the same time, the external power switch of the fan 201 is turned on, and the input end of the fan 201 generates suction, which draws the treated gas inside the gas treatment tank 1 into the exhaust pipe 2, and further discharges the treated gas through the exhaust pipe 202. As the gas flows rapidly under the guidance of the fan 201, the turbine blades 208 are located inside the exhaust pipe 2. When the gas passes through the turbine blades 208, it further drives the turbine blades 208 to rotate. The two fixed plates 203 support the support ring 204, allowing the transmission rod 205 to be installed inside the gas treatment tank 1 via 204. The transmission rod 205 can rotate through the bearing. When the turbine blade 208 rotates, it drives the transmission rod 205 to rotate, which in turn causes the multiple stirring plates 206 to rotate. When the multiple stirring plates 206 rotate, they stir the gas and catalyst inside the gas treatment tank 1, allowing them to fully mix together, increasing their reaction rate, and further improving the gas treatment efficiency. As multiple stirring plates 206 rotate, they drive multiple arc-shaped scrapers 207 to rotate as well. These scrapers 207 adhere closely to the inner wall of the gas treatment tank 1, scraping the catalyst within the tank and preventing reactants or catalyst from adhering to the inner wall under heat. The external power switch of the wastewater pump 308 is turned on, allowing the wastewater inside the storage tank 301 to be discharged through the first drain pipe 307 into the second drain pipe 309 under the action of the pump. The wastewater is then further treated in the wastewater treatment tank 310, and the treated wastewater is discharged through the drain pipe 401 into the heat insulation pipe 4. When the gas treatment tank 1 is treating the gas inside, multiple heating tubes 209 are in the open state, and the water discharged into the insulation pipe 4 is heated at the same time. When the external power switch of the delivery pump 403 is turned on, the input end of the delivery pump 403 generates suction, which discharges the heated water inside the insulation pipe 4 through the first connecting pipe 402 into the second connecting pipe 404, and further into the hot water tank 405 inside the storage tank 301. Under the action of the hot water pump 303, the waste gas inside the spray tower 3 is treated again through the delivery pipes 302 and 304. The hot water is recycled to complete the treatment of the waste gas.

Any person skilled in the art can modify or alter the technical content disclosed in the above embodiments to create equivalent embodiments that are applied to other fields. However, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the essence of the present invention shall still fall within the scope of protection of the present invention.
