[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] In this utility model, when the water pump is started, the cooling water in the water storage tank is pumped up through the water suction pipe and conveyed upward into the water diversion pipe. When the cooling water flows through the nozzle orifice of the nozzle in the water diversion pipe, it enters the nozzle and is sprayed out from the spray holes opened at the bottom of the nozzle, and is sprayed into the waste gas in the form of fine droplets, greatly increasing the contact area between water and waste gas, enhancing the effect of evaporative cooling of the waste gas, achieving rapid cooling.

The design of the slots and insertion plates can ensure the precise alignment and engagement between the cylinders, which is a key factor to further ensure the accuracy and stability of the entire chimney structure. At the same time, the use of the fastening screw can provide reliable fastening for the engagement between the insertion hole and the insertion block, making a firm connection between the cylinders.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: an assembled chimney with waste gas purification treatment, including an intake pipe 1, one end of the intake pipe 1 is inserted into one side of the bottom cylinder 2, the top end of the bottom cylinder 2 is clamped with a middle cylinder 3, a spray mechanism 4 is horizontally penetrated through one side of the middle cylinder 3, the bottom end of the spray mechanism 4 vertically penetrates through the top side of the water storage tank 5, a connecting pipe 6 is horizontally penetrated through the outer wall of one side of the water storage tank 5, the other end of the connecting pipe 6 is inserted into one side of the water collection box 7, the top end of the middle cylinder 3 is clamped with a top cylinder 8, a filter mechanism 9 is embedded in the inner wall of the top cylinder 8, an exhaust pipe 10 is arranged in the middle of the top of the top cylinder 8, slots 11 are arranged on the outer walls of the top ends of the bottom cylinder 2 and the middle cylinder 3, and plug boards 12 are arranged on the outer walls of the bottom ends of the top cylinder 8 and the middle cylinder 3.

[0024] In this embodiment, as Figure 2 and Figure 3As shown in the figure, a first card slot 201 is opened at the top of the bottom cylinder 2, a second card slot 301 is opened at the top of the middle cylinder 3, a first card strip 302 is provided at the bottom of the middle cylinder 3, a second card strip 801 is provided at the bottom of the top cylinder 8, and a sealing rubber ring is adhesively bonded to the top ends of the bottom cylinder 2 and the middle cylinder 3; it should be noted that in the present utility model, the chimney is divided into three independent cylinders: upper, middle, and lower. During the assembly process, the operator only needs to vertically insert the first card strip 302 provided at the bottom of the middle cylinder 3 into the first card slot 201 opened at the top of the bottom cylinder 2, and then vertically insert the second card strip 801 provided at the bottom of the top cylinder 8 into the second card slot 301 opened at the top of the middle cylinder 3, so that the two cylinders can be snapped together. During this period, the sealing rubber rings adhesively bonded to the top ends of the bottom cylinder 2 and the middle cylinder 3 will be respectively subjected to the pressure exerted by the bottom ends of the middle cylinder 3 and the top cylinder 8, and thus be squeezed and deformed, thereby compensating for the gaps between the contact surfaces of the cylinders and achieving the sealing closure of the cylinder assembly. Through the cooperation of the card slots and the card strips, the various parts of the chimney can be quickly assembled and fixed on-site. At the same time, the cooperation between the first card strip 302 and the first card slot 201, as well as the second card strip 801 and the second card slot 301, is precise, which can also ensure the alignment and positioning of the cylinders, guaranteeing that the overall structure of the chimney is both aligned and stable in the vertical direction, which is beneficial to improving the structural integrity and load-bearing capacity of the chimney. The design of the sealing rubber ring improves the sealing performance between the cylinders, prevents the entry of waste gas, rainwater, and other substances, and also blocks the lateral flow of gas inside the cylinders, ensuring the airtightness of the chimney.

[0025] In this embodiment, as Figure 2 and Figure 6 shown, the spray mechanism 4 is composed of a water pump 401, a water suction pipe 402, a water guiding pipe 403, and a spray head 404. The water suction pipe 402 is respectively inserted into the upper and lower ends of the water pump 401. The lower water suction pipe 402 vertically penetrates through one side of the top of the water storage tank 5, and the upper water suction pipe 402 is inserted into the water guiding pipe 403. A number of spray heads 404 are equidistantly arranged at the top of the water guiding pipe 403; it should be noted that the waste gas enters the bottom cylinder 2 from the intake pipe 1 and then flows upward into the middle cylinder 3. At the same time, the operator can start the water pump 401 to draw the cooling water in the water storage tank 5 through the water suction pipe 402 and convey it upward into the water guiding pipe 403. When the cooling water flows through the nozzle orifice of the spray head 404 in the water guiding pipe 403, it enters the spray head 404 and is sprayed out from the spray holes opened at the bottom of the spray head 404 and combines with the waste gas in the cylinder. During this process, the spray head 404 sprays the cooling water in the form of fine droplets into the waste gas, which can greatly increase the contact area between the water and the waste gas, enhance the effect of waste gas evaporation cooling, thereby quickly reducing the temperature of the waste gas and improving the treatment efficiency. At the same time, the spray-type cooling water can effectively capture the fine particles in the waste gas. Through the collision and coagulation of the droplets and the particles, it helps the settlement and removal of the particles, thereby reducing the content of particles discharged into the atmosphere.

[0026] In this embodiment, as shown in Figure 2 and Figure 6 shown, on one side of the inner wall of the water storage tank 5, there is a baffle 501, and on the other side, there is a filter net 502. In the middle of the top wall and the bottom wall of the water storage tank 5, there is a filter core material 503. It should be noted that when the water suction pipe 402 pumps and conveys the cooling water in the water storage tank 5 into the water guiding pipe 403, so that the cooling water flows into the nozzle 404 and sprays out from the spray holes opened at the bottom of the nozzle 404, its droplets will contact the waste gas inside the middle cylinder 3, thereby cooling it. After achieving spray cooling, the droplets will continue to fall downward under the action of gravity to the water collecting box 7 at the bottommost part, and be collected through the water permeable holes 701 opened at its top. When the droplets accumulate into sewage, they will flow back into the water storage tank 5 through the connecting pipe 6, and contact the filter core material 503 provided inside it, filtering and intercepting the tiny particulate matters in the sewage, and converting it into clean water that can be used. When the water flows through the filter core material 503, it will gradually soak through the filter net 502 and gather on the upper layer of the water storage tank 5, facilitating the water suction pipe 402 to perform the water suction operation again. The originally used water is filtered by the filter core material 503 and recycled, reducing the dependence on fresh water sources, thereby reducing the purchase and treatment costs of water, improving economic benefits. At the same time, the baffle 501 can block the sewage from polluting the clean water source while allowing the sewage to pass through, and the filter core material 503 further removes the remaining impurities, effectively preventing the secondary pollution of water and keeping the water circulation system clean.

[0027] In this embodiment, as shown in Figure 2 and Figure 6 shown, several water permeable holes 701 are opened at the top of the water collecting box 7. It should be noted that when the droplets fall downward under the action of gravity on the top of the water collecting box 7, they will directly pass through the water permeable holes 701 opened on its surface and enter the inside of the water collecting box 7 and be collected. When the droplets in the box converge into sewage, the sewage water flow will flow towards the connecting pipe 6 on one side of the water collecting box 7, enter the pipeline interior, and flow back into the water storage tank 5 along the pipeline for the next filtering operation to be restored into clean water that can be reused again. During this process, through the connection of the connecting pipe 6, the designed water collecting box 7 and the water storage tank 5 form a water recycling system. After the droplets used for spray cooling are collected by the water collecting box 7 and filtered by the filter core material 503, they can be reused, which not only saves water resources but also reduces the operating cost. Moreover, the water permeable holes 701 opened at the top of the water collecting box 7 can block a part of the dust and impurities while allowing the droplets to pass through, which can reduce the load of the filter core material 503 and collect the relatively clean water, thereby improving the filtering efficiency.

[0028] In this embodiment, as shown in Figure 5As shown in the figure, the filtering mechanism 9 is composed of a fixed frame 901, a first filtering layer 902, a second filtering layer 903 and a third filtering layer 904. The fixed frame 901 is fitted and placed on the inner wall of the top cylinder 8, and the first filtering layer 902, the second filtering layer 903 and the third filtering layer 904 are filled in the fixed frame 901 from top to bottom in sequence. It should be noted that after the waste gas in the middle cylinder 3 is cooled by the spraying mechanism 4, it will continue to flow upward until it reaches the inside of the top cylinder 8. At this time, the waste gas will come into contact with the first filtering layer 902, the second filtering layer 903 and the third filtering layer 904 in the filtering mechanism 9 in sequence, so as to complete the filtration and purification of the waste gas. The first filtering layer 902 filters out large particles and relatively rough dust in the waste gas, the second filtering layer 903 removes finer particles and some microorganisms in the waste gas, such as bacteria and viruses, and the third filtering layer 904 removes harmful gases such as sulfur and nitrogen compounds in the waste gas. Through multiple filtering layers, the treatment efficiency of the gas can be improved, the energy consumption can be reduced, the requirements of modern industrial emission standards can be met, the long-term operation cost can be reduced, and the impact on the environment can be reduced. The fitting placement of the fixed frame 901 can also be taken out from the inner wall of the top cylinder 8, which is convenient for replacing the filtering layer inside it.

[0029] In this embodiment, as Figure 1 and Figure 3 and Figure 4As shown in the figure, the slot 11 is a square orifice plate with jacks 1101 formed on its surface. The plug board 12 is a T-shaped plug board 12, and a plug block 1201 is provided at the center of the bottom. Screw holes are formed on the same side of the jack 1101 and the plug block 1201. It should be noted that when the first clamping strip 302 provided at the bottom of the middle cylinder 3 is vertically inserted into the first clamping groove 201 formed at the top of the bottom cylinder 2, and then the second clamping strip 801 provided at the bottom of the top cylinder 8 is vertically inserted into the second clamping groove 301 formed at the top of the middle cylinder 3, so that the cylinders are clamped together pairwise, the plug block 1201 of the plug board 12 provided on the outer wall of the bottom end of the middle cylinder 3 will be vertically inserted into the jack 1101 formed in the slot 11 on the outer wall of the top end of the bottom cylinder 2, and the plug block 1201 of the plug board 12 provided on the top of the top cylinder 8 will be vertically inserted into the jack 1101 formed in the slot 11 on the outer wall of the top end of the middle cylinder 3. At the same time, the screw holes formed on the sides of the two combined jacks 1101 and the plug block 1201 will be aligned. At this time, a fastening screw is used and screwed into the corresponding screw hole, so as to screw the two groups of slots 11 and the plug board 12 together, thereby realizing the fixed assembly between the cylinders pairwise. The design of the slot 11 and the plug board 12 can ensure the precise alignment and engagement between the cylinders, which is a key factor to further ensure the accuracy and stability of the entire chimney structure. At the same time, the use of the fastening screw can provide reliable fastening for the engagement between the jack 1101 and the plug block 1201, so that a firm connection is formed between the cylinders. This fastening method is simple and easy to implement, and can be quickly loosened when necessary, facilitating on-site maintenance and repair.

[0030] The usage method and advantages of the present utility model: For this assembled chimney with waste gas purification treatment, during use, the working process is as follows:

[0031] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, first, the operator needs to vertically insert the first clamping strip 302 provided at the bottom of the middle cylinder 3 into the first clamping groove 201 opened at the top of the bottom cylinder 2, and then vertically insert the second clamping strip 801 provided at the bottom of the top cylinder 8 into the second clamping groove 301 opened at the top of the middle cylinder 3, so that the two cylinders can be clamped together with each other. At the same time, the insertion block 1201 of the insertion plate 12 provided on the outer wall of the bottom end of the middle cylinder 3 will vertically insert into the insertion hole 1101 opened in the slot 11 on the outer wall of the top end of the bottom cylinder 2, and the insertion block 1201 of the insertion plate 12 provided on the top of the top cylinder 8 will vertically insert into the insertion hole 1101 opened in the slot 11 on the outer wall of the top end of the middle cylinder 3. During this period, the insertion holes 1101 of the two combinations and the screw holes opened on the side of the insertion block 1201 will be aligned. At this time, use fastening screws and screw them into the corresponding screw holes to screw the two groups of slots 11 and insertion plates 12 together, thereby realizing the fixed assembly between the two cylinders. Then, waste gas can be introduced into the intake pipe 1. At this time, the waste gas enters the bottom cylinder 2 and flows upward into the interior of the middle cylinder 3. At the same time, start the water pump 401, extract and transport the cooling water in the water storage tank 5 to the water diversion pipe 403 through the water extraction pipe 402. The cooling water flows along the water diversion pipe 403 and passes through the nozzle of the nozzle 404 and enters it. Then, it sprays out from the spray holes opened at the bottom of the nozzle 404 and combines with the waste gas in the cylinder to cool down. After being cooled by the spraying mechanism 4, the waste gas will continue to flow upward until it reaches the interior of the top cylinder 8 and contacts the first filter layer 902, the second filter layer 903, and the third filter layer 904 in the filtering mechanism 9 in sequence, so as to filter out harmful gases such as large particles, microorganisms, and sulfur and nitrogen compounds in the waste gas. Through the multi-layer filter layer, the purified gas meets the requirements of the emission standard and is discharged outward along the exhaust pipe 10 provided at the top of the top cylinder 8.
