[0016] The anesthetic waste gas collection and purification device of the present utility model has the following advantages:

[0017] 1. The anesthetic waste gas collection and purification device, by setting up the waste gas spray purification structure, first injects the anesthetic waste gas exchange liquid into the high-pressure gas storage cylinder. After the air pump sucks the anesthetic waste gas into the high-pressure gas storage cylinder, then closes the valve on the surface of the gas pipeline. After that, drives the water pump to pump the anesthetic waste gas exchange liquid in the high-pressure gas storage cylinder into the fan-shaped spray head and spray it out. Thus, the anesthetic waste gas exchange liquid can be sprayed on the anesthetic waste gas in the high-pressure gas storage cylinder in the form of water mist, so that the anesthetic waste gas exchange liquid can convert the anesthetic waste gas.

[0018] 2. The anesthetic waste gas collection and purification device, by setting up the adsorption purification structure, when the waste gas is completely converted, opens the valve on the surface of the gas pipeline.

[0031] To better understand the purpose, structure and function of the present utility model, the following further describes in detail an anesthetic waste gas collection and purification device of the present utility model with reference to the accompanying drawings.

[0032] As Figures 1-5 shown, an anesthetic waste gas collection and purification device of the present utility model includes a high-pressure gas storage cylinder 1. A pressure valve is provided on the surface of the high-pressure gas storage cylinder 1, and the pressure valve is used to monitor the pressure inside the high-pressure gas storage cylinder 1.

[0033] An exhaust gas spray purification structure is provided inside the high-pressure gas storage cylinder 1.

The other end of the drain pipe 10 is fixedly connected to the water inlet end of the sector-shaped spray head 8.

[0034] Inject anesthetic waste gas exchange liquid into the high-pressure gas storage cylinder 1. The anesthetic waste gas exchange liquid is a liquid used to treat anesthetic waste gas and is prior art, so it will not be elaborated here. After that, driving the water pump 9 can use the water pump 9 to pump the anesthetic waste gas exchange liquid along the drain pipe 10 into the sector-shaped spray head 8, and the sector-shaped spray head 8 can spray the anesthetic waste gas exchange liquid in a mist form.

[0035] The gas supply component includes a coil pipe 11 fixedly installed on the inner wall of the high-pressure gas storage cylinder 1. The coil pipe 11 is located directly below the sector-shaped spray head 8. A plurality of air outlet holes 12 are equidistantly arranged on the surface of the coil pipe 11. An air inlet pipe 13 is fixedly installed at the air inlet end of the coil pipe 11. The other end of the air inlet pipe 13 extends to the outside of the high-pressure gas storage cylinder 1 and is fixedly installed with an air pump 14. An air connection pipe 15 is fixedly installed at the air inlet end of the air pump 14, and a one-way valve 16 is provided on the surface of the air inlet pipe 13. Driving the air pump 14 can pump the anesthetic waste gas into the high-pressure gas storage cylinder 1 along the air connection pipe 15 and the air inlet pipe 13, and use the coil pipe 11 to divide the waste gas into multiple strands and spray it out along the air outlet holes 12.

[0036] Above the high-pressure gas storage cylinder 1, an adsorption and purification structure is provided. The adsorption and purification structure is composed of a filling cylinder 2, a partition component arranged inside the filling cylinder 2, a desiccant 3, activated carbon 4, and a cover plate 5 that can block the filling cylinder 2. At the upper end of the high-pressure gas storage cylinder 1, a support rod 23 is fixedly installed, and the other end of the support rod 23 is fixedly connected to the lower end of the filling cylinder 2. The filling cylinder 2 can be supported by the support rod 23.

[0037] The filling cylinder 2 and the high-pressure gas storage cylinder 1 are interconnected through a gas transmission pipe 6. A valve 17 is arranged on the surface of the gas transmission pipe 6, and a support mesh plate 18 is fixedly installed on the inner wall of the gas transmission pipe 6. An exhaust pipe 7 is fixedly installed at the upper end of the cover plate 5.

[0038] First, an anesthetic waste gas exchange liquid is injected into the high-pressure gas storage cylinder 1. After the air pump 14 sucks the anesthetic waste gas into the high-pressure gas storage cylinder 1, then the valve 17 on the surface of the gas transmission pipe 6 is closed. After that, the water pump 9 is driven to pump the anesthetic waste gas exchange liquid in the high-pressure gas storage cylinder 1 into the fan-shaped spray head 8 and sprayed out, so that the anesthetic waste gas exchange liquid can be in a water mist state to spray the anesthetic waste gas in the high-pressure gas storage cylinder 1, and then the anesthetic waste gas exchange liquid can convert the anesthetic waste gas.

[0039] The partition component includes a retaining ring 21 fixedly installed on the inner wall of the filling cylinder 2. A placement groove is formed on the upper surface of the retaining ring 21, and a partition mesh plate 22 is arranged on the inner wall of the placement groove. The desiccant 3 is placed on the inner bottom wall of the filling cylinder 2. At this time, the support mesh plate 18 will support the desiccant 3. Then the partition mesh plate 22 is placed into the retaining ring 21, and then the activated carbon 4 is placed on the partition mesh plate 22, so that the activated carbon 4 and the desiccant 3 can be separated.

A sealing ring 20 is arranged on the inner wall of the sealing groove. After the activated carbon 4 and the desiccant 3 are placed into the filling cylinder 2, then the cover plate 5 is screwed onto the filling cylinder 2. At this time, the sealing ring 20 will seal the connection gap between the cover plate 5 and the filling cylinder 2, so as to avoid gas leakage.

[0041] When the waste gas is completely converted, the valve 17 on the surface of the gas transmission pipe 6 is opened. The waste gas first passes through the desiccant 3 to absorb the water mist in the high-pressure gas storage cylinder 1, and then the activated carbon 4 is used to adsorb other harmful substances in the waste gas. The absorbed waste gas will be discharged from the exhaust pipe 7, so as to avoid the water mist in the high-pressure gas storage cylinder 1 from wetting the activated carbon 4 and affecting the use of the activated carbon 4. At the same time, the partition component can separate the activated carbon 4 from the desiccant 3 and avoid the desiccant 3 from wetting the activated carbon 4 after getting wet.

[0042] Compared with the prior art, after the device uses an air pump 14 to inhale anesthetic waste gas into the high-pressure gas storage cylinder 1, the high-pressure gas storage cylinder 1 can store the anesthetic waste gas. Then, the spray component is used to pump the anesthetic waste gas exchange liquid into the fan-shaped spray head 8 and spray it out. Thus, the anesthetic waste gas in the form of water mist can be used to circulate and spray-convert the anesthetic waste gas, increasing the contact area between the anesthetic waste gas and the anesthetic waste gas exchange liquid, improving the conversion rate, and further enabling the complete conversion of the waste gas.
