[0030] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.
[0031] The process gas generated during the operation of the chemical plant often contains some particulate impurities or useless gas, at which time it is necessary to use dust removal or purification equipment to remove it. For a large amount of gas purification treatment, a special dust remover or purification equipment can be set up, and generally the dust remover or purification equipment is large in size and needs to occupy a large space for installation. However, for a device with a small amount of gas running, the cost of setting up a large device is high, and the large device will occupy a large space, which may cause installation difficulties, thereby making dust removal or purification difficult.
[0032] Based on this, the gas purification device 1000 provided in the embodiment of the present application can effectively improve the technical problems mentioned above. The gas purification device 1000 can be used for dust removal or purification of a small amount of gas, and has the advantages of simple structure, small space occupation and low manufacturing cost. The gas purification device 1000 can be applied to a gas purification system, and the gas purification system with the gas purification device 1000 also has the same function.
[0033] The gas purification system in the embodiment includes a fan and the gas purification device 1000. The air inlet of the fan is communicated with the equipment generating waste gas, and the air outlet of the fan is communicated with the gas purification device 1000. The fan is used for extracting and pushing the waste gas in the equipment generating waste gas into the gas purification device 1000 for dust removal or purification treatment, so as to obtain gas meeting the discharge standard. Of course, the gas purification system can also include other devices to realize various functions of the gas purification system, such as a washing device. The specific composition of the gas purification system is determined according to actual use requirements, and is not limited herein.
[0034] Figure 1 A schematic view of the gas purification device 1000 provided in the embodiment of the present application is shown in the figure; Figure 2 A schematic view of the first view angle of the pipeline 100 provided in the embodiment of the present application is shown in the figure; Figure 3 A schematic view of the second view angle of the pipeline 100 provided in the embodiment of the present application is shown in the figure, Figure 1 , Figure 2 and Figure 3 As shown in the figures, the gas purification device 1000 in the embodiment includes a pipeline 100 and a shell 200. A partition plate 300 is arranged in the pipeline 100 to divide the pipeline 100 into a first pipeline 110 and a second pipeline 120. Filter holes 130 are formed in the first pipeline 110 and the second pipeline 120. The shell 200 wraps part of the first pipeline 110 and part of the second pipeline 120, and is used for covering the filter holes 130. An adsorbent is filled in the shell 200. In the embodiment, the first pipeline 110 is communicated with the equipment generating waste gas. The waste gas enters the first pipeline 110, flows into the shell 200 through the filter holes 130 of the first pipeline 110, and passes through the adsorbent in the shell 200. The adsorbent adsorbs some harmful component substances in the waste gas, so as to achieve the effect of purifying the waste gas. The purified gas flows into the pipeline 100 again through the filter holes 130 of the second pipeline 120, and then is discharged or flows into the next purification equipment or other equipment. Of course, other gases can also enter from the second pipeline 120 and be discharged from the first pipeline 110, which is not limited herein.
[0035] By setting the partition 300, the pipeline 100 can be separated, and the gas cannot directly flow out through the pipeline 100. By setting the shell 200, the shell 200 wraps the pipeline 100 having the filter hole 130, and the gas needs to flow through the filter hole 130 to flow from the gas inlet of the pipeline 100 to the gas outlet of the pipeline 100. In addition, because the shell 200 is filled with the adsorbent, the gas entering the shell 200 through the filter hole 130 of the first pipeline 110 or the second pipeline 120 reacts with the adsorbent in the shell 200, and then the purified gas is discharged from the pipeline 100 through the filter hole 130 of the second pipeline 120 or the first pipeline 110.
[0036] Please refer to Figure 1 The above-mentioned "the shell 200 wraps part of the first pipeline 110 and part of the second pipeline 120", specifically, the shell 200 in the embodiment is buckled on the outer wall of part of the first pipeline 110 and part of the second pipeline 120. That is, the shell 200 can be composed of two separate parts, and the two parts are connected in a buckling manner and buckled on the pipeline where the filter hole 130 exists to cover the filter hole 130. After the first pipeline 110 is connected with the equipment generating waste gas, the first pipeline 110 forms a closed space, and the gas entering the first pipeline 110 can only flow through the adsorbent of the shell 200 after the filter hole 130 and then be discharged to the second pipeline 120. Of course, the shell 200 can also be designed as a whole and is sleeved into the pipeline 100 or buckled to wrap the filter hole 130 of the pipeline. As long as the shell 200 tightly adheres to the outer wall of the pipeline 100 to ensure that the gas does not leak from the filter hole 130, the connection mode of the shell 200 and the pipeline 100 is not limited herein. The connection between the shell 200 and the pipeline is achieved by buckling, which can facilitate filling or replacing the adsorbent in the shell 200 and is also convenient for installation.
[0037] Please continue to refer to Figure 1 The shell 200 in the embodiment is spherical. Of course, the shell 200 can also be designed as a cuboid, a cube or other shapes, as long as it can cover the filter hole 130 and ensure that the gas does not leak from the filter hole 130. The specific shape of the shell 200 is not limited herein.
[0038] In order to increase the contact area between the gas and the adsorbent, the adsorbent in the present embodiment is a granular adsorbent, such as silica gel, activated carbon, polymer, etc. The adsorbent in the present embodiment is activated carbon. Activated carbon is a porous carbon-containing substance, which has a highly developed pore structure. The porous structure of activated carbon provides a large surface area, which can be in full contact with the gas (impurities), thereby giving activated carbon its unique adsorption properties, making it very easy to achieve the purpose of absorbing impurities. Just like magnetic force, all molecules have mutual attraction. Because of this, the large number of molecules on the pore wall of activated carbon can produce strong attraction, thereby achieving the purpose of attracting harmful impurities into the pore diameter. The larger the surface area of activated carbon, the stronger the adsorption capacity. Activated carbon is a non-polar molecule, which is easy to adsorb non-polar or very low polar adsorbate. The size of activated carbon adsorbent particles, the structure and distribution of fine pores, and the surface chemical properties have a great influence on adsorption. Of course, the adsorbent can also be made into blocks, honeycombs and other shapes, which are determined according to the actual purification needs, and are not limited here.
[0039] In addition, in addition to filling the adsorbent in the shell 200, other gas purification substances such as desiccant can also be filled in the shell 200 to achieve the required various purified gases.
[0040] Please refer to Figure 2 and Figure 3 In order to avoid the adsorbent entering the pipeline 100, which is inconvenient to clean and replace, the pore diameter of the gas filtering hole 130 in the present embodiment is smaller than the diameter of the adsorbent.
[0041] Please continue to refer to Figure 2 and Figure 3 The number of gas filtering holes 130 in the present embodiment is multiple, and the multiple gas filtering holes 130 are arranged in the circumferential direction and the axial direction of the pipeline 100. By arranging multiple gas filtering holes 130, the exchange rate of the gas can be accelerated. The gas filtering hole 130 in the present embodiment is a circular hole. Of course, the gas filtering hole 130 can also be designed as a square or other regular or irregular shape, which is not limited here.
[0042] In order to install the gas purification device 1000 into the equipment generating waste gas, the gas purification device 1000 in the present embodiment further comprises a flange connector, which is arranged at the open end of the first pipeline 110, and / or the flange connector is arranged at the open end of the second pipeline 120. The flange connector is used to communicate the pipeline 100 with the gas outlet of the equipment generating waste gas.
[0043] The exhaust gas is generally discharged to the outdoor or recycled after purification. The gas purification device 1000 in the embodiment can also be modified to one end pipeline 100 of the exhaust pipeline of the device generating exhaust gas. The one end pipeline 100 of the exhaust pipeline is provided with a baffle 300, and a plurality of filter holes 130 are formed in the pipeline 100 on both sides of the baffle 300. The filter holes 130 are sleeved with a shell 200, the filter holes 130 are closed, the pipeline forms a closed space, and the shell 200 is filled with an adsorbent. The gas flows in the pipeline, and when the gas reaches the position of the baffle 300, it can only enter the shell 200 from the filter holes 130 of the pipeline on one side of the baffle 300, pass through the adsorbent to adsorb some harmful substances, and then enter the pipeline 100 again through the filter holes 130 of the pipeline on the other side of the baffle 300, and then the purified gas is discharged. In this way, the structure of the entire device can be simplified, the cost can be reduced, and it is not necessary to additionally occupy space to set a dust remover or a purification device, the space utilization rate is improved, and the exhaust gas can be purified in the case of insufficient space.
[0044] According to the gas purification device 1000 provided in the embodiment, the working principle is as follows:
[0045] The gas flows into the pipeline 100 from the gas inlet, and in the embodiment, the opening of the first pipeline 110 is the gas inlet, and the opening of the second pipeline 120 is the gas outlet. That is, the gas to be purified flows into the first pipeline 110, flows out to the shell 200 through the filter holes 130 of the first pipeline 110, and reacts with the adsorbent in the shell 200 to obtain the purified gas. Then the purified gas flows into the second pipeline 120 through the filter holes 130 of the second pipeline 120, and flows out from the opening of the second pipeline 120.
[0046] In summary, the gas purification device 1000 comprises a pipeline 100 and a shell 200, the pipeline 100 is provided with a partition plate 300 to divide the pipeline 100 into a first pipeline 110 and a second pipeline 120, and the first pipeline 110 and the second pipeline 120 are both provided with filter holes 130. The shell 200 wraps part of the first pipeline 110 and part of the second pipeline 120, and is used for covering the filter holes 130; and the shell 200 is filled with an adsorbent. The pipeline 100 is divided by the partition plate 300, so that the gas cannot flow out of the pipeline 100 directly. The shell 200 is arranged, and the pipeline 100 with the filter holes 130 is wrapped by the shell 200, so that the gas needs to flow through the filter holes 130 to flow from the gas inlet of the pipeline 100 to the gas outlet of the pipeline 100. In addition, the shell 200 is filled with the adsorbent, so that the gas enters the shell 200 through the filter holes 130 of the first pipeline 110 or the second pipeline 120, reacts with the adsorbent in the shell 200, and then is discharged from the pipeline 100 through the filter holes 130 of the second pipeline 120 or the first pipeline 110. The gas purification device 1000 can meet the demand of small amount of gas purification, and does not need to be separately arranged with installation space of the device, so that the space can be saved. In addition, the device has simple structure, convenient installation, and low cost of operation and maintenance.
