Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agents, in particular to a waste gas treatment device for concrete water reducing agent production. Background Art

[0002] Concrete water reducer is a chemical additive used in the concrete preparation process. It can improve the fluidity and plasticity of concrete by changing the physical properties of concrete. Specifically, water reducers can reduce the viscosity of concrete, increase the fluidity of concrete, reduce the amount of cement used in concrete, and improve the strength and durability of concrete to a certain extent. They absorb moisture on the surface of cement particles, reduce the friction and surface tension between particles, making concrete easier to flow and vibrate, and form a dense gel structure after the concrete solidifies.

[0003] Concrete water reducer will produce waste gas during production. Direct discharge of such gas will cause environmental pollution and needs to be treated before discharge. This requires the use of waste gas treatment equipment for water reducer production to treat the waste gas.

[0004] After searching, it is proposed in a waste gas treatment device for water reducing agent production with patent publication number CN220609556U that "the utility model can treat the waste gas transported to the treatment tank by setting the filter core body, and can clean the bottom of the filter core body by setting the rotating handle, rotating rod, driving bevel gear, driven bevel gear, rotating shaft and brush plate, so that the filter core body can be cleared without disassembling the filter core body, and the operation is convenient. By setting the above structure, it has the advantage of convenient cleaning of multi-stage filter cores";

[0005] However, the above solution still has certain shortcomings in actual use. The solution only uses a filter element to treat the waste gas generated in the production process of concrete water reducing agent, resulting in that the effect of waste gas treatment cannot be guaranteed.

[0025] The inner wall of the purification box 201 is slidably connected with a water collecting tank 207 , the top of the purification box 201 is fixedly installed with a water storage box 208 , the bottom of the water storage box 208 is fixedly installed with an atomizing nozzle 209 , and the atomizing nozzle 209 is located above the water collecting tank 207 .

[0026] A socket 211 is fixedly mounted on the inner wall of the purification box 201 , and a filter plate 212 is movably plugged into the socket 211 .

[0027] By setting up the exhaust gas purification device 2, the exhaust gas and the neutralizing liquid inside the mixing barrel 205 can be mixed and stirred by using the stirring shaft 206, so that the pH value of the exhaust gas is neutralized, and then the atomizing nozzle 209 can make the water inside the water storage box 208 contact with the exhaust gas in the form of mist, and then the particulate impurities in the exhaust gas are wetted to form dust reduction treatment, and three filter plates 212 can be used to adsorb and filter different types of debris in the exhaust gas, so that the exhaust gas is treated in multiple stages, thereby improving the treatment effect.

[0028] The waste gas combustion device 3 includes a processing box 301, an igniter 302 is fixedly installed on the inner wall of the processing box 301, and a combustion nozzle 303 is fixedly connected to the outer wall of the igniter 302. An air quality sensor 304, a reflux air pump 305 and an exhaust air pump 306 are arranged on the outer side of the processing box 301, and the other end of the reflux air pump 305 is connected to the one-way air valve 204.

[0029] The working principles of the igniter 302 and the combustion nozzle 303 have been developed in a water reducing agent waste gas treatment device with patent publication number CN220824652U, and will not be repeated here.

[0030] By setting up the waste gas combustion device 3, the igniter 302 is used to perform an oxidation combustion reaction on the waste gas located inside the processing box 301 through the combustion nozzle 303, so that the remaining impurities in the waste gas are burned out, so that the waste gas at this time can meet the emission requirements.

[0031] Specifically, an extraction pump 210 is fixedly installed at the bottom end of the water storage box 208 , and a connecting hose is provided at the bottom end of the extraction pump 210 , and the other end of the connecting hose penetrates into the interior of the water collection tank 207 .

[0032] In this embodiment, the water inside the water collection tank 207 is pumped into the water storage box 208 again by using the extraction pump 210, so that this part of the water can circulate in the water storage box 208 and the water collection tank 207.

[0033] Specifically, the filter plate 212 is an activated carbon adsorption plate, and an external handle is fixedly connected to the top of the filter plate 212 , and the external handle extends to the top of the purification box 201 .

[0034] In this embodiment, the waste gas is filtered and adsorbed by the filter plate 212, so that the impurities, odor and antibacterial properties of the waste gas are effectively adsorbed and inhibited.

[0035] When in use, the waste gas in the production reactor 1 is first introduced into the stirring barrel 205 in the purification box 201 through the one-way valve. Since the stirring barrel 205 is pre-filled with clean water and neutralizing compounds, the waste gas will directly contact the clean water and the neutralizing compounds. Then, the stirring shaft 206 is started, so that the stirring shaft 206 starts to mix and stir the waste gas and the neutralizing compound liquid in the stirring barrel 205, so that the pH value of the waste gas is neutralized.

[0036] Then, the unreacted waste gas will rise and transfer to the top of the water collection tank 207 under the drive of the guide fan 203, and then the atomizing nozzle 209 will be started, so that the atomizing nozzle 209 can spray the water in the water storage box 208 in the form of mist, so that the particulate impurities in the waste gas will contact with the water mist, so that the particulate impurities in the waste gas will be wetted and fall into the water collection tank 207;

[0037] The water in the water collection tank 207 is pumped into the water storage box 208 again by using the extraction pump 210, so that this part of the water can circulate in the water storage box 208 and the water collection tank 207;

[0038] Then, the exhaust gas after dust reduction will contact the filter plate 212 driven by the guide fan 203, so that the filter plate 212 can absorb and filter the impurities in the exhaust gas;

[0039] After the exhaust gas is adsorbed, it enters the treatment box 301, and then the igniter 302 and the combustion nozzle 303 start to ignite the inside of the treatment box 301, so that the combustion nozzle 303 performs an oxidation combustion reaction on the exhaust gas inside the treatment box 301, so that the remaining impurities in the exhaust gas are completely burned;

[0040] The purified exhaust gas will then be tested by the air quality sensor 304, and those that meet the standards will be directly discharged from the exhaust air pump 306. When the gas is unqualified, the exhaust air pump 306 will be closed and the reflux air pump 305 will be opened in time, so that the exhaust gas will enter the one-way air valve 204 again through the reflux air pump 305 and undergo a second round of processing.

[0041] In summary, the waste gas treatment device for concrete water reducing agent production, by setting the waste gas purification device 2, can mix and stir the waste gas and the neutralizing liquid in the mixing barrel 205 by using the stirring shaft 206, so that the pH of the waste gas is neutralized, and then cooperate with the atomizing nozzle 209 to make the water in the water storage box 208 contact with the waste gas in the form of mist, and then wet the particulate impurities in the waste gas to form dust reduction treatment, and use three filter plates 212 to adsorb and filter different types of impurities in the waste gas, so that the waste gas is treated in multiple stages, thereby improving the treatment effect;

[0042] By setting up the waste gas combustion device 3, the igniter 302 is used to perform an oxidation combustion reaction on the waste gas located inside the processing box 301 through the combustion nozzle 303, so that the remaining impurities in the waste gas are burned out, so that the waste gas at this time can meet the emission requirements.
