Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to a waste gas purification device in the production of silicon oxide spherical powder. Background Art

[0002] Silica spherical powder, that is, spherical silicon dioxide powder, is an important inorganic non-metallic material. In the production process of silica spherical powder, a certain amount of waste gas will be generated. These waste gases often contain particulate matter and other harmful substances. If they are directly discharged into the atmosphere, they will have adverse effects on the environment. Therefore, it is an indispensable part of the production of silica spherical powder to treat the waste gas and reduce its harmful substance content. The waste gas purification device is required to treat the waste gas generated in the production of silica spherical powder, but the existing waste gas purification device still has the following defects:

[0003] However, when purifying the waste gas produced during the production of silicon oxide spherical powder, the existing purification device generally directly uses an activated carbon adsorption device to adsorb organic pollutants in the waste gas.

[0033] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0037] like Figure 1-8 As shown, this embodiment proposes a waste gas purification device in the production of silicon oxide spherical powder, including a purification tank body 1, a purification mechanism 2 is arranged outside the purification tank body 1, an acceleration component 3 is arranged on the top of the purification tank body 1, and a collection component 4 is arranged on the acceleration component 3.

[0038] like Figure 3 , Figure 6 and Figure 7As shown, the purification mechanism 2 includes a mounting frame 201, a filter plate 202, an air intake pipe 203, a delivery pump 204, a connecting pipe 205, a water spray pipe 206, a nozzle 207, an exhaust pipe 208, a waste pipe 209 and a solenoid valve 210. The mounting frame 201 is fixedly connected to the inner wall of the purification tank body 1, the filter plate 202 is fixedly connected to the inner wall of the mounting frame 201, the air intake pipe 203 is connected and arranged on the outer wall of the purification tank body 1, the delivery pump 204 is bolted to the outer wall of the purification tank body 1, the connecting pipe 205 is fixedly connected to the output end of the delivery pump 204, the water spray pipe 206 is arranged inside the purification tank body 1 and is connected with the connecting pipe 205, the nozzle 207 is arranged at the bottom of the outer wall of the water spray pipe 206, and the exhaust pipe 208 is connected and arranged at At the top of the purification tank body 1, the waste pipe 209 is connected and arranged on the outer wall of the bottom end of the purification tank body 1, the solenoid valve 210 is arranged on the outside of the waste pipe 209, and the water spray pipe 206 is located above the filter plate 202. When in use, the delivery pump 204 draws the external purification liquid into the water spray pipe 206, and then discharges it through the nozzle 207. The discharged purified liquid falls on the filter plate 202, and then passes through the filter plate 202 and falls to the bottom of the purification tank body 1. Then the external exhaust gas enters the purification tank body 1 through the air inlet pipe 203. At this time, the purified liquid contacts the exhaust gas, thereby performing heat exchange and reducing the temperature of the exhaust gas. When the purified liquid contacts the exhaust gas, the exhaust gas will be purified. The purified gas penetrates the filter plate 202 and is then discharged to the external environment from the exhaust pipe 208.

[0039] like Figure 3 and Figure 4 As shown, the acceleration component 3 includes a connecting rod 301, a fixing ring 302, a support rod 303 and a swirl blade 304. The connecting rod 301 is fixedly connected to the inner wall of the exhaust pipe 208, the fixing ring 302 is fixedly connected to one end of the connecting rod 301, the support rod 303 is fixedly connected to the inside of the fixing ring 302, and the swirl blade 304 is arranged on the outer wall of the support rod 303. There are four connecting rods 301 and they are distributed circumferentially along the central axis of the support rod 303. There are several swirl blades 304 and they are distributed circumferentially along the central axis of the support rod 303. When the purified exhaust gas enters the exhaust pipe 208, the exhaust gas will be guided by the swirl blade 304, thereby generating a swirl. Under the action of centrifugal force, the swirl throws out the moisture in the gas, thereby improving the quality of the exhaust gas.

[0040] like Figure 3 and Figure 5As shown, the collecting component 4 includes a collecting chamber 401, a water inlet hole 402 and a drain hole 403. The collecting chamber 401 is opened in the wall of the exhaust pipe 208, the water inlet hole 402 is opened on the side wall of the exhaust pipe 208 and is connected to the collecting chamber 401, and the drain hole 403 is opened at the bottom of the exhaust pipe 208 and is connected to the interior of the collecting chamber 401. The number of the water inlet holes 402 and the drain holes 403 are both several and are distributed along the circumference of the central axis of the exhaust pipe 208. When the moisture in the water is thrown out, the water inlet hole 402 can collect the moisture, and the moisture passing through the water inlet hole 402 enters the interior of the collecting chamber 401, and then is discharged from the drain hole 403 to the interior of the purification tank body 1, thereby reusing water resources.

[0041] like Figure 3 As shown, a guide ring 5 is provided at the inner top of the purification tank body 1. The guide ring 5 is made of stainless steel. The top and bottom of the guide ring 5 are respectively fixedly connected to the inner top wall and the inner side wall of the purification tank body 1. When in use, the guide ring 5 can guide the gas that has not entered the exhaust pipe 208, so that the gas can enter the exhaust pipe 208 more easily.

[0042] like Figure 3 As shown, a water guide ring 6 is fixedly connected to the top of the installation frame 201. The cross-sectional shape of the water guide ring 6 is a right triangle. The straight side of the cross-sectional shape of the water guide ring 6 is fixedly connected to the inner wall of the purification tank body 1. When in use, the water guide ring 6 can prevent the purified liquid from staying on the top of the installation frame 201, so that the purified liquid can be utilized to the greatest extent.

[0043] like Figure 3 As shown, a fixing rod 7 is fixedly connected to the inner wall of the purification tank body 1, and a limiting ring 8 is fixedly connected to one end of the fixing rod 7. When in use, the fixing rod 7 and the limiting ring 8 are used in combination to fix the water spray pipe 206 to prevent the water spray pipe 206 from shaking when the purification liquid moves inside the water spray pipe 206.

[0044] like Figure 3 As shown, the bottom of the filter plate 202 is fixedly connected with a water guide plate 9, and the material of the water guide plate 9 is stainless steel. When in use, a part of the liquid descending from the filter plate 202 will be guided by the water guide plate 9, thereby forming a water curtain, thereby increasing the contact area between the purified liquid and the exhaust gas, and thus improving the cooling efficiency.

[0045] like Figure 1 and Figure 3As shown, a water inlet pipe 10 is connected to the outer wall of the purification tank body 1, and a one-way valve 11 is arranged on the water inlet pipe 10. The input end of the delivery pump 204 is fixedly connected to a circulation pipe 12. One end of the circulation pipe 12 is connected to the inner bottom of the purification tank body 1. When in use, the water inlet pipe 10 can conveniently add purification liquid to the inside of the purification tank body 1. At the same time, the purification liquid in contact with the exhaust gas will fall on the inner bottom of the purification tank body 1. At this time, the circulation pipe 12 can reuse the waste liquid. After the waste liquid is utilized, the solenoid valve 210 is opened to discharge the liquid from the waste pipe 209 to the outside.

[0046] like Figure 3 As shown, an isolation net 13 is fixedly connected to the inside of the purification tank body 1. The isolation net 13 is located above the bottom end of the circulation pipe 12. The isolation net 13 is located between the bottom end of the circulation pipe 12 and the water inlet pipe 10. When in use, the isolation net 13 can intercept solid particles generated when purifying the gas to prevent the solid particles from entering the circulation pipe 12.

[0047] like Figure 8 As shown, a storage cavity 14 is opened inside the bottom wall of the purification tank body 1, and a heating wire 15 is arranged inside the storage cavity 14. When in use, the storage cavity 14 can heat the waste liquid or the purified liquid entering the purification tank body 1 through the water inlet pipe 10, thereby increasing the reaction speed between the purified liquid and the waste gas.

[0048] Specifically, when the waste gas purification device in the production of silicon oxide spherical powder is used: the heating wire 15, the delivery pump 204 and the electromagnetic valve 210 are connected to the external power supply, and then the purification liquid is added from the water inlet pipe 10 in advance, and then the delivery pump 204 is started. The delivery pump 204 draws the purification liquid into the circulation pipe 12, the connecting pipe 205 and the water spray pipe 206 in sequence, and then sprays it out through the nozzle 207. Then the purification liquid penetrates the filter plate 202. At this time, the external waste gas is passed into the inlet pipe 203, and then the purification liquid penetrated from the filter plate 202 and the waste gas is mixed with the purification liquid. The purified gas passes through the filter plate 202 and is then guided by the guide ring 5 to the inside of the exhaust pipe 208, and then is guided by the swirl blades 304 to generate a swirl. Under the action of centrifugal force, the swirl throws out the moisture in the gas, and then the water inlet hole 402 can collect the moisture, and the moisture passing through the water inlet hole 402 enters the collection chamber 401, and then is discharged from the drainage hole 403 to the inside of the purification tank body 1, thereby reusing water resources.

[0049] All technical features in this embodiment can be freely combined according to actual needs.

[0050] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
