Description

Technical Field

[0001] The invention relates to the technical field of gas separation, and in particular to a waste gas treatment device. Background Art

[0002] Anesthetic waste gas is a mixture containing volatile anesthetic agents. If it is directly discharged into the atmosphere without treatment, it will pollute the environment and bring potential harm to human health. Therefore, hospitals and medical institutions generally collect and treat anesthetic waste gas through anesthetic waste gas recovery equipment. The basic principle of anesthetic waste gas recovery equipment is to separate volatile anesthetic drug components from anesthetic waste gas through adsorption, condensation, catalytic oxidation and other technical means, and then reuse or safely dispose of them. The recovery equipment consists of a collection tube and an absorption tank. The absorption tank is filled with activated carbon for adsorbing anesthetic vapor or gas. During use, water vapor exhaled by the human body will also enter the recovery tank with the anesthetic waste gas. The water vapor contacts the activated carbon and competes with the anesthetic waste gas for adsorption sites, reducing the adsorption capacity of the activated carbon for anesthetic waste gas and affecting the treatment effect of the anesthetic waste gas.

[0004] When the anesthetic waste gas treatment device provided by the above patent document treats anesthetic waste gas, the flow rate of the waste gas needs to be precisely controlled during the process of the anesthetic waste gas blowing water vapor into the top of the inverted cone-shaped metal cover. If the flow rate of the waste gas is too fast, the water vapor may not be fully gathered on the top of the inverted cone-shaped metal cover, and then be carried out of the cooling unit, so that the water vapor in the waste gas cannot be fully separated, resulting in unsatisfactory separation effect of the water vapor in the waste gas. If the waste gas flow rate is too slow, it will affect the collection efficiency of the waste gas by the treatment device. Summary of the invention

[0031] like Figures 1 to 3 As shown, a plurality of condensation plates 21 are evenly arranged in the inner circumference of the condensation member 2, and a condenser 213 is also arranged inside the condensation member 2. Each condensation plate 21 is connected to the condenser 213 through a connecting rod 212. The condenser 213 is used to ensure the cooling effect of each condensation plate 21, wherein the condenser 213 belongs to a condensation element in the prior art, and the specific structure of the condenser 213 is not described here. Each condensation plate 21 is spirally arranged on the inner wall of the condensation member 2 and has the same spiral direction. The plate surface height of each condensation plate 21 is along the direction close to the condensation member. 2, the high ends of the two condensation plates 21 arranged apart are opposite to each other and are located on the same busbar of the condensation member 2, and the two adjacent condensation plates 21 are overlapped in the spiral direction of the condensation plates 21, wherein the overlapping range of the two adjacent condensation plates 21 is half of the length of the plate body of the condensation plate 21, and the small end of the condensation member 2 is detachably provided with a storage cavity 22, and the condensation member 2 is provided with a plurality of guide components, each guide component corresponds to each condensation plate 21 one by one, and is used to guide the condensed water on the condensation plate 21 into the storage cavity 22.

[0032] After the anesthetic waste gas enters the shell 1 from the air inlet, it moves from the small end of the condensation piece 2 to the large end of the condensation piece 2, and enters the interior of the condensation piece 2 through the gap at the large end of the condensation piece 2. A channel for guiding the anesthetic gas is formed between any two adjacent condensation plates 21. The anesthetic gas is in full contact with each condensation plate 21 in the condensation piece 2, extending the condensation range of water vapor and promoting the condensation of water vapor in the anesthetic gas on the surface of the condensation plate 21.

[0033] like Figure 1 , Figure 4 and Figure 5As shown, the side wall of the filter element 3 is provided with a plurality of groups of filter units 31, and each group of filter units 31 is evenly arranged in the circumferential direction of the filter element 3. The filter unit 31 includes a mounting portion and a filter plate. The anesthetic gas after the condensation operation further passes through the filter plate of each filter unit 31, and the filter plate adsorbs the anesthetic waste gas after the water vapor treatment. The anesthetic waste gas treated by the filter unit 31 is discharged through the gas outlet 4 and enters the subsequent processing and collection operation.

[0034] In order to timely process the water vapor condensed on the condensation plate 21, a cleaning component is also provided on the filter 3. When the driving member 37 drives the filter 3 to rotate relative to the condensation member 2, the cleaning component cleans the condensed liquid on each condensation plate 21. The cleaning component includes a connecting member 32, a movable member 33 and a cleaning member 34. A notch is provided on the filter 3, and the length direction of the notch is parallel to the generatrix direction of the filter 3. The connecting member 32 is fixed relative to the filter 3. A connecting groove 321 parallel to the notch is provided on the connecting member 32. The movable member 33 and the cleaning member 34 are both The movable part 33 slides along the length direction of the connecting groove 321, and the movable part 33 slides and fits with the side wall of the connecting groove 321. The cleaning part 34 extends from the connecting groove 321 and the notch, and slides and fits with the plate surface intervals of each condensation plate 21. The cleaning part 34 can slide along the length direction and depth direction of the connecting groove 321 at the same time. The depth direction of the connecting groove 321 is perpendicular to the length direction of the connecting groove 321. The cleaning part 34 is located on the inner side of the movable part 33, and the inner end of the movable part 33 is kept in contact with the outer end of the cleaning part. The cleaning part 34 includes a cleaning portion 341 and a connecting portion 342. The cleaning portion 341 is used to slide against the condensation plate 21. The connecting portion 342 is located on the inner side of the cleaning portion 341. The connecting portion 342 slides with the connecting groove 321. The cleaning portion 341 is located between the connecting portion 342 and the movable part 33. The cleaning portion 341 slides with the connecting portion 342 along the depth direction of the connecting groove 321 to prevent the waste gas from directly passing through the cleaning portion 34 and the movable part 33 into the filter element 3 and being discharged when the waste gas treatment device is working, so as to ensure that the anesthetic waste gas enters the filter element 3 after being filtered by the filter unit 31, thereby ensuring the treatment effect of the waste gas.

[0035] The movable part 33 is connected to the connecting part 32 through the elastic part 1 331, and the cleaning part 34 is connected to the connecting part 32 through the elastic part 2 and the elastic part 343. Specifically, the cleaning part 341 is connected to the connecting part 32 through the elastic part 2, and the connecting part 342 is connected to the connecting part 32 through the elastic part 343. When the cleaning part 341 moves toward the inside of the filter element 3 along the depth direction of the connecting groove 321, it squeezes the elastic part 2 and makes the elastic part 2 accumulate force. When the connecting part 342 moves inward, it squeezes the elastic part 343 and makes the elastic part 343 accumulate force. When the cleaning part 341 moves outward, it pushes the movable part 33 to move synchronously. The movable part 33 squeezes the elastic part 1 331 and makes the elastic part 1 331 accumulate force. The elastic part 1 331, the elastic part 2 and the elastic part 343 in this embodiment can all be springs. When the elastic part 1 331 and the elastic part 2 are not stretched or squeezed, the position of the cleaning part 341 is opposite to the lower end of the condensation plate 21.

[0036] When the driving member 37 drives the filter element 3 to rotate, the cleaning portion 341 slides from the lower end of the condensation plate 21 to the plate surface of the condensation plate 21. As the filter element 3 rotates, the cleaning portion 341 adheres to the plate surface of the condensation plate 21 and gradually moves toward the high end of the condensation plate 21. In the process of the cleaning portion 341 adhering to the condensation plate 21, the condensed liquid on the condensation plate 21 is pushed to flow upward. Because the height of the condensation plate 21 decreases in the direction close to the inner wall of the condensation element 2, the liquid can be effectively prevented from sliding from the gap between the condensation plate 21 and the filter element 3 during the movement on the condensation plate 21. In order to ensure the cleaning effect of the liquid on the condensation plate 21, the height of the cleaning portion 341 matches the gap between the two condensation plates 21, so that the cleaning portion 341 is simultaneously in contact with the inner end face and the outer end face of the two adjacent condensation plates 21, and cleans them. The cleaning portion 341 pushes the accumulated liquid to move to a higher place of the condensation plate 21.

[0037] like Figure 3 As shown, a plurality of groups of flow guide components are also provided on the condensing member 2, and a storage chamber 22 is detachably provided at the inner end of the condensing member 2. The connection methods between the storage chamber 22 and the condensing member 2 include but are not limited to threaded fitting, snap-on connection and plug-in fitting. Each group of flow guide components corresponds to each condensing plate 21 one by one. When the cleaning portion 341 pushes the liquid to the top of the condensing plate 21, the accumulated liquid flows into the storage chamber 22 through the flow guide component and is collected. The flow guide component includes a liquid inlet 231, a flow guide channel 23 and a liquid outlet 232. The flow guide channel 23 is arranged in the side wall of the condensing member 2, the liquid inlet 231 is arranged at the high end of the condensing plate 21 and is communicated with the flow guide channel 23, and the liquid outlet 232 is arranged at the lower end of the condensing member 2 and is communicated with the storage chamber 22.

[0038] A stopper 211 is also provided at the high end of the condensation plate 21, and the end face of the stopper 211 opposite to the condensation plate 21 is in the shape of an inclined plane. After the cleaning part 341 pushes the liquid into the liquid inlet 231, it gradually contacts the stopper 211, and slides along the depth direction of the connecting groove 321 under the extrusion of the stopper 211, avoiding the stopper 211, and at the same time extruding the elastic member 2 to store force. A limiting structure is also provided between the cleaning part 341 and the movable member 33, and the limiting structure includes a limiting groove 35 and a limiting block 36. The limiting groove 35 is provided on the outer end face of the cleaning part 341, and the limiting block 36 is provided on the inner end face of the movable member 33. The limiting block 36 elastically slides with the movable member 33, and the cleaning part 341 avoids the stopper 211. When the block 211 slides relative to the connecting groove 321, the limiting block 36 on the movable part 33 is opposite to the limiting groove 35 on the cleaning part 341, and the limiting block 36 extends into the limiting groove 35 to block the cleaning part 341 from moving along the depth direction of the connecting groove 321. The width of the blocking block 211 is consistent with the width of the condensing plate 21. When the cleaning part 341 is limited by the limiting structure, it does not contact the condensing plate 21. When the cleaning part 341 slides from the lower end to the higher end of the condensing plate 21, it slides outward in the connecting groove 321 and pushes the movable part 33 to slide synchronously, and at the same time squeezes the elastic part 1 331 to store force. When the connecting part 342 slides with the cleaning part 341 in the connecting groove 321, it pulls the elastic part 2 to store force. When the cleaning part 341 is limited by the limiting structure, under the elastic force of the elastic member 1 331 and the elastic member 343, the movable member 33 and the cleaning member 34 slide inward along the connecting groove 321. A guide groove is provided on the inner wall of the connecting groove 321, and the limiting block 36 slides in cooperation with the guide groove. When the cleaning part 341 moves to be opposite to the lower end of the condensation plate 21, the elastic force of the elastic member 1 331 and the elastic member 343 is released. At the same time, the guide groove blocks the sliding of the limiting block 36 and causes the limiting block 36 to be separated from the limiting groove 35. The cleaning portion 341 is again aligned with the lower end of another condensation plate 21 that is set apart, and repeats the cleaning operation of the liquid on the condensation plate 21. To ensure that the liquid on each condensation plate 21 can be cleaned, at least two groups of cleaning components can be set. In order to clean the liquid on the condensation plate 21 in time and improve the cleaning effect of the condensed liquid on the condensation plate 21, multiple groups of cleaning components can be set as needed, wherein the number of cleaning components can be consistent with the number of condensation plates 21, and each group of cleaning components corresponds to each condensation plate 21 one by one.

[0039] In order to further improve the sealing strength between the cleaning part 341 and the movable part 33, a sealing structure is further provided between the cleaning part 341 and the movable part 33. The sealing structure includes a sealing groove and a sealing strip. The sealing strip is provided on the inner end surface of the movable part 33 and protrudes relative to the inner end surface of the movable part 33. The sealing groove is provided on the outer end surface of the cleaning part 341. The sealing strip is fitted with the sealing groove. The material of the sealing strip can be rubber.

[0040] The waste gas treatment device provided by the present invention facilitates full contact of water vapor in anesthetic waste gas, promotes full condensation of water vapor on the condensation plate, and cleans the liquid on the condensation plate in time through the cleaning component.
