Description

Technical Field

[0001] The utility model relates to the technical field of gas purification and treatment, and more specifically to a gas washing device which can improve the gas washing efficiency. Background Art

[0002] Gas scrubbing is an operation commonly performed in laboratories to remove impurities from gases. The principle is to pass impure gas into a gas scrubbing bottle filled with an absorbent, and use the dissolution or chemical reaction between the impurities and the absorbent to remove the impurities, thereby achieving the purpose of purifying the gas. When using existing gas scrubbing bottles for gas scrubbing, one gas scrubbing bottle can only remove impurities of a certain specific component. If multiple impurities in the gas are to be removed, multiple gas scrubbing bottles are required to be loaded with different absorbents, and then these gas scrubbing bottles are assembled in series with rubber hoses. Glass is a fragile material and consumes more instrument assembly time and occupies more laboratory bench space. In summary, how to efficiently use gas scrubbing bottles to conveniently and efficiently remove a variety of gas impurities has become a technical problem to be solved by technicians in this field. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a laboratory gas washing device with high strength, good safety, and stable comprehensive gas washing efficiency, which can replace the absorbing material at any time.

[0004] To achieve the above-mentioned purpose and other related purposes, the utility model provides a laboratory gas washing device, including an air inlet pipe, an air outlet pipe, a gas washing bottle, a gas washing box, a flow meter, and a threaded fixing. The air outlet pipe is connected to the air inlet pipe. The gas washing bottle device can be added with solid or liquid absorption materials. The gas washing device can be spliced ​​according to different needs. Multiple overlapping applications of the utility model can remove various impurities in the gas.

[0005] Preferably, the gas washing bottle and the gas washing cabinet box are both provided with threaded fixings, the inner diameter of which matches the outer diameter of the air inlet pipe and the air outlet pipe. The gas washing bottle can be sleeved with the air inlet pipe and the air outlet pipe to ensure their sealing.

[0006] Preferably, the gas washing bottle is a detachable device and can be replaced and connected at any time.

[0007] Preferably, the upper opening of the gas washing bottle is a feed opening, and the lower opening is a discharge opening. The bottom box plate is provided with a plurality of circular openings, the size of which matches the lower opening of the gas washing bottle, so as to facilitate the placement of the gas washing bottle. The feed opening and the discharge opening are composed of bolt fasteners and sealing plates. The gas washing material can enter through the feed opening and be taken out through the discharge opening. When cleaning, the upper and lower sealing plates are cleaned according to the operating requirements. The specific operation is as follows.

[0008] The technical solution provided by the utility model has the following significant effects compared with the prior art: after the gas containing impurities reaches the gas washing bottle device through the air inlet pipe, the gas flow rate is controlled by observing the flow meter, and the gas passes through quickly and efficiently. Since the absorption material in the gas washing bottle can be selected as liquid or solid according to demand, the corresponding gas washing step can be selected according to demand, and the redundant gas washing bottles can be used as safety bottles. The box body made of high-strength material can better protect the safety and stability of the gas washing process, and the absorption liquid after gas washing can be conveniently collected for research. The utility model has a simple structure, is easy to use, and has a high comprehensive gas washing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the utility model, the utility model is further described below in conjunction with preferred embodiments and drawings. Similar components in the drawings are represented by the same reference numerals. Those skilled in the art should understand that the content described below is illustrative rather than restrictive, and should not be used to limit the scope of protection of the utility model.

[0013] A gas washing device for a laboratory comprises an air inlet pipe, an air outlet pipe, a gas washing bottle, a gas washing box, a flow meter and a threaded fixing piece. The gas washing bottle and the gas washing box are formed separately, and the detachable gas washing bottle is connected through the threaded fixing piece.

[0014] In this embodiment, the feed inlet and the discharge outlet of the gas washing bottle are composed of bolt fasteners and a sealing plate.

[0015] In this embodiment, the material used for the box body is stainless steel.

[0016] In this embodiment, both the air inlet and the air outlet are provided with threaded fasteners.

[0017] In this embodiment, the box plate is hinged to the box body, so that the box plate can move flexibly.

[0018] In this embodiment, when all the bolts are removed from the bolt holes, the sealing cover can be directly removed from the exhaust gas treatment bottle.

[0019] When using the utility model patent, the box plate 10 is opened by the hinge 9 to sequentially put the exhaust gas treatment bottle 5, tighten the threaded fasteners 3 of each unit, and then the box plate 10 is closed by the hinge 9, the bolt fasteners 7 of each exhaust gas treatment bottle 5 are loosened, the bolt fasteners 7 are taken out, the sealing cover 6 is opened, the absorption liquid or absorbent is put in, the sealing cover 6 is closed, the bolt fasteners 7 are put into the bolt hole and tightened, and the gas to be treated passes through the intake pipe 1 and the intake long tube 4, and after the absorption liquid or absorbent in the starting exhaust gas treatment bottle 5 acts, it passes through the intake long tube 4 of the next exhaust gas treatment bottle 5 and enters the next exhaust gas treatment bottle 5, and the gas to be treated repeats the above process, and the gas to be treated is in the last exhaust gas treatment bottle 5, and the gas outlet 8 is completed.
