Description

[Technical Field]

[0001] The present invention relates to a mobile toxic gas purification device, and more particularly to a mobile toxic gas purification device that is movable and portable and can purify toxic gases regardless of location or space. [Background technology]

[0002] Toxic gases emitted in chemical processes, semiconductor manufacturing processes, and various industrial sites are highly toxic, explosive, and corrosive, and are harmful to the human body. If released directly into the atmosphere, they can cause environmental pollution. Therefore, in order to purify such toxic gases, semiconductor manufacturing processes and various industrial sites have installed intake and exhaust systems using air conditioning ducts and dampers to exhaust toxic gases generated in enclosed spaces such as factories and chambers to the outside and to draw in and circulate outside air into the interior space, thereby purifying the interior air.

[0003] Previously, Korean Patent Publication No. 10-2017-0063088 disclosed an air purifier that can automatically remove harmful gases generated in enclosed spaces in various industrial sites, including semiconductor production sites, by filtering various fine particulate matter and dust particles, as well as first removing harmful elements in the air at production sites, such as VOC gases, through a thermal catalytic reaction, and then secondarily and thirdly removing harmful viruses and bacteria in the air through the supply of sterilized water and irradiation with ultraviolet light, thereby maintaining comfortable indoor air and preventing air pollution.

[0004] However, conventional air purifiers have to be fixedly installed in exhaust pipes, and can only purify in designated spaces. They are not portable or mobile, making them unsuitable for various spaces. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been developed to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a mobile toxic gas purification device that is movable and portable. [Means for solving the problem]

[0006] The mobile purification device of the present invention includes a case having an inlet on one side for sucking in toxic gas and an outlet on the other side for purifying and discharging the sucked air, a plurality of flow path sections for separating the toxic gas sucked into the inlet, a plurality of purification sections independently provided in each of the plurality of flow path sections for purifying the toxic gas, a route determination section provided at a branching point of the plurality of flow path sections based on the concentration of the toxic gas and determining a route for moving the toxic gas to one of the plurality of purification sections, a distribution section connected to the route determination section and distributing the toxic gas so that it flows into one of the plurality of purification sections, and a power supply section having a rechargeable battery provided inside the case. [Effects of the Invention]

[0007] The mobile purification device of the present invention is equipped with a battery unit, and can be directly dragged by workers to adsorb and filter toxic gases in small, enclosed spaces in various industrial sites, including semiconductor production sites, thereby enabling purification of toxic gases regardless of location or space.

[0008] In addition, the mobile purification device according to the present invention has replaceable adsorbents inside the first canister and second canister depending on the type of toxic gas to be purified, which has the effect of enabling purification of various toxic gases.

[0009] In addition, in the mobile purification device according to the present invention, when the adsorbent installed inside either the first canister or the second canister reaches its usage limit, toxic gas can flow into either the first canister or the second canister, thereby improving purification efficiency.

[0028] Fig. 1 shows a structural diagram of a mobile purification device of the present invention, and Fig. 2 shows a schematic diagram of the mobile purification device of the present invention. Referring to Fig. 1 and Fig. 2, a mobile purification device 1000 of the present invention includes a case 100, a flow path unit 300, a purification unit, a path determination unit 200, a distribution unit 210, and a power supply unit.

[0029] FIG. 3 illustrates a front view of a mobile purification device according to the present invention, and FIG. 4 illustrates a rear view of the mobile purification device according to the present invention. Referring to FIGS. 3 and 4, the case 100 has an inlet 110 on one side for drawing in toxic gases and an outlet 120 on the other side for purifying and discharging the drawn-in air. The case 100 may be made of materials such as stainless steel or reinforced plastic, and has an internal space for accommodating components. Toxic gases generated from the outside are drawn into the inlet 110 of the case 100, and the purified air is absorbed into the case 100 and discharged to the outside through the outlet 120 of the case 100. The inlet 110 may further include a suction pipe for drawing in toxic gases. The suction pipe is formed at the inlet 110 and can directly draw in external toxic gases, thereby further improving the efficiency of toxic gas intake.

[0030] Next, the toxic gas sucked through the suction port 110 flows into the plurality of flow passage units 300. The plurality of flow passage units 300 separate the paths of the toxic gas sucked through the suction port 110. The plurality of flow passage units 300 each include a plurality of purification units that are independently provided in the plurality of flow passage units 300 and purify the toxic gas.

[0031] The purification unit includes a canister, a filter, and a blower. The canister contains a replaceable adsorbent capable of adsorbing toxic gases and is configured to adsorb the incoming toxic gases. The toxic gases are then filtered again by the filter to remove any remaining toxic gases or fine particles before being discharged from the canister as purified air. The filtered air is then discharged through the blower and the outlet 120. The purification unit includes a first purification unit and a second purification unit, each connected to one of the plurality of flow path units 300. The first purification unit includes a first canister 311 that adsorbs the toxic gases that have flowed in from one of the plurality of flow path units 300, a first filter 312 that filters the toxic gas adsorbed from the first canister 311, and a first blower 313 that exhausts the toxic gas filtered from the first filter 312 to the outside. The second purification unit includes a second canister 321 that adsorbs the toxic gas flowing in from any one of the plurality of flow path units 300, a second filter 322 that filters the toxic gas adsorbed from the second canister 321, and a second blower 323 that exhausts the toxic gas filtered from the second filter 322 to the outside. In addition, the first canister 311 and the second canister 321 are provided with replaceable adsorbents depending on the type of toxic gas to be purified inside the first canister 311 and the second canister 321.

[0032] In addition, a branching point of the plurality of flow passages 300 through which toxic gas is supplied to the inlet 110 of the housing further includes a path determination unit 200 and a distributor 210 to control the toxic gas flowing into the first and second purification units connected to any one of the plurality of flow passages 300. The path determination unit 200 is provided at the branching point of the plurality of flow passages 300 based on the concentration of the toxic gas and determines a path to direct the toxic gas to any one of the plurality of purification units. When toxic gas flows into the inlet 110, it may flow into either the first canister 311 or the second canister 321, which contains an adsorbent. Here, when the adsorbent provided in either the first canister 311 or the second canister 321 reaches its usage limit, the path determination unit 200 may determine a path so that the toxic gas flows into either the first canister 311 or the second canister 321. The path determination unit 200 also includes a distribution unit 210 connected to the path determination unit 200, which distributes the toxic gas flowing into one of the plurality of purification units. The distribution unit 210 includes a valve control unit which controls a valve provided in the distribution unit 210 to adjust the amount of toxic gas flowing into one of the plurality of purification units. In order to increase the suction efficiency of the toxic gas controlled by the distribution unit 210, the amount of toxic gas flowing into one of the first canister 311 or the second canister 321 can be controlled or blocked. By controlling the inflow amount of toxic gas flowing into the first canister 311 or the second canister 321 in this manner, the purification efficiency of the first canister 311 or the second canister 321 can be improved.

[0033] The case 100 further includes an exhaust space separating the first filter 312 and the first blower 313, which filter and exhaust toxic gases adsorbed from the first canister 311 and the second canister 321, and the second filter 322 and the second blower 323. The exhaust space further includes a sensor 220 that detects the concentration of toxic gases remaining in the purified air before the purified air is exhausted from the exhaust port. The sensor 220 further includes a detection control unit that exhausts the purified air from the exhaust port if the concentration of toxic gases remaining in the purified air is not detected, and activates the second canister 321 included in the purifier if the concentration of toxic gases remaining in the purified air is detected. Here, the sensor 220 senses the concentration of toxic gases in the purified air exhausted to the exhaust space. If the sensor 220 does not detect any residual toxic gases in the purified air, the purified air is exhausted from the exhaust port. Here, the exhaust space communicates with the exhaust port of the case 100. By communicating the exhaust space with the exhaust port, the toxic gas flowing in from the inlet and the purified air in the exhaust space are prevented from mixing, and the concentration of the residual toxic gas can be accurately determined by the sensing unit 220, resulting in more efficient purification. Furthermore, when the sensing unit 220 senses residual toxic gas in the purified air, the sensing control unit activates one of the first canister 311 and the second canister 321, thereby re-purifying the residual toxic gas and exhausting it from the exhaust port.

[0034] The first canister 311 and the second canister 321 each include an adsorbent therein. The adsorbent can be replaced depending on the type of toxic gas to be purified. For example, if the toxic gases to be purified in the first canister 311 and the second canister 321 are two types of toxic gases, a first toxic gas and a second toxic gas, the first canister 311 may include an adsorbent capable of purifying the first toxic gas, and the second canister 321 may include an adsorbent capable of purifying the second toxic gas. The first canister 311 and the second canister 321 may alternately operate to purify the toxic gases.

[0035] Next, the mobile purification device 1000 further includes a power supply unit (not shown), which includes a rechargeable battery inside the case 100. The power supply unit (not shown) may further include a charging unit that can charge the battery. Referring to the rear view of the mobile purification device of the present invention in FIG. 4, the mobile purification device 1000 has wheels 500 for movement at the bottom and a handle 600 at the top, which allow it to be moved freely. The mobile purification device 1000 also includes a power supply unit (not shown) equipped with a battery. This allows workers to directly drag the mobile purification device 1000 around in small, enclosed spaces at various industrial sites, including semiconductor production sites, to adsorb and filter toxic gases, enabling purification of toxic gases regardless of location or space.

[0036] Fig. 5 is a plan view of the mobile purification device of the present invention. Referring to Fig. 5, the mobile purification device 1000 of the present invention includes a display unit 400 located outside the case 100, a first canister mounting unit 401, and a second canister mounting unit 402.

[0037] The display unit 400 measures the concentration of the gas discharged from the outlet 120 and displays the measured gas concentration. Here, the air filtered inside the mobile purification device 1000 is discharged from the outlet 120 via a blower, and the concentration of toxic gas measured by the sensing unit 220 is displayed on the display unit 400. Before the filtered air is discharged, it is possible to confirm whether the filtered air contains toxic gases from the measured gas concentration displayed on the display unit 400, thereby confirming whether the air has been purified.

[0038] The first canister 311 is attached to the first canister attachment portion 401, and the second canister 321 is attached to the second canister attachment portion 402. The adsorbents in the first canister 311 and the second canister 321 can be replaced depending on the type of toxic gas to be purified, and the first canister 311 and the second canister 321 can be separated by the first canister attachment portion 401 and the second canister attachment portion 402, allowing the appropriate adsorbent to be replaced and used depending on the type of toxic gas to be purified, thereby achieving the effect of enabling purification of various toxic gases.

[0039] The display unit 400 further includes a battery display unit (not shown) that displays the charging status of the battery provided in the power supply unit. The battery display unit (not shown) allows the user to check the charging status of the battery in real time, charge the battery regardless of location or space, and purify toxic gases easily and quickly.

[0040] Figure 6 is a photograph of the mobile purification device of the present invention. Referring to Figure 6, the mobile purification device of the present invention has wheels 500 for mobility at the bottom and a handle 600 at the top, which allow it to be moved freely. It also has a power supply unit equipped with a battery, so that workers can directly pull the mobile purification device around in the narrow and enclosed spaces of various industrial sites, including semiconductor production sites, to adsorb and filter toxic gases, making it possible to purify toxic gases regardless of location or space.

[0041] The present invention is not limited to the above-described embodiments, and it goes without saying that the scope of application is varied, and that various modifications can be made without departing from the gist of the present invention as claimed in the claims.
