Fully-enclosed circular reagent cabinet

Abstract

The invention relates to a fully-enclosed circular reagent cabinet, comprising a first reagent storeroom and a second reagent storeroom, a decontamination chamber, a lateral conduit, a bottom conduit, a first upper suction inlet and a second upper suction inlet, a first bottom outlet and a second bottom outlet, wherein the polluted air in the first reagent storeroom and the second reagent storeroom passes through the first and the second upper suction inlets and a first annular fan and a second annular fan which are arranged above the first and the second upper suction inlets to form an upward airflow, so as to be absorbed in the decontamination chamber; and the air is purified by a filter column, the purified air forms a downward airflow through the lateral conduit, then the air passes through the bottom conduit which is communicated with the lateral conduit and is discharged upwards from the first and the second bottom outlets for continuous circulation. According to the invention, by improving internal circulation flow direction to effectively clean the air in the reagent cabinet and using partitions to separate the left and right spaces to greatly raise the storage capacity, the personal safety is guaranteed, the pro-environmental property is achieved without air pollution, and the minimization of the quality reduction of the reagents.

Description

technical field [0001] The invention relates to a fully enclosed circulation reagent cabinet, which is aimed at storing various reagents necessary for research tasks in universities or enterprise laboratories or research rooms, so that personal safety can be guaranteed, and environmental protection can be maintained. There is no air pollution, and it ensures that the quality of the reagents decreases to a minimum; in detail, through the double-sided reagent storage room divided by the partition, the polluted air flows upwards and is sucked into the upper clean room. The high-performance filter effectively purifies and neutralizes harmful gases such as volatile organic compounds or odors and dust generated in the reagent storage room, and then passes through the narrow tube formed on the side of the reagent storage room on one side to form the purified air. In order to flow downward, through the lower pipe connected to the above-mentioned side pipe, through the first lower disc...

Problems solved by technology

[0004] Accordingly, this existing filter column purification and discharge type reagent cabinet adopts a circulation structure in which the harmful gas or odor polluted air generated inside is mixed with the air introduced from the room, and then discharged to the room after being purified by the filter. The atmosphere and dust enter the inside of the reagent cabinet and pass through the filter column, resulting in low function of the filter column and greatly reducing the life of the filter column. For such a reagent cabinet structure, when the purification efficiency of the filter column is reduced, it will become a pollution experimenter. or the main cause of indoor air where researchers live

[0005] As far as the filtration and purification discharge type or simple ventilation type reagent cabinets are concerned, as mentioned above, in order to avoid the pollution of indoor air, the pipes are connected to the reagent cabinets and then led to the outdoor discharge structure. It is convenient to transfer the reagent cabinet, and the indoor air is forced to be exhausted to the outside, which affects the indoor temperature, and there is a problem of harmful gas or odor being discharged to the outside to pollute the atmosphere

[0006] As a technical solution to solve the problems caused by the above-mentioned prior art, Korean Patent No. 10-0476403 adopts the method of repeatedly circulating the air in the closed space inside the reagent cabinet and purifying it with a filter column without exhausting the air inside the reagent cabinet indoors or outdoors. technology, disclosed as Figure 7 Shown is provided with the reagent cabinet (1 ') that decomposes the catalyst material of malodorous and poisonous gas, and above-mentioned existing reagent cabinet (1 ') is by reagent keeping room (2) and is positioned at its clean room (3), and The filter (4) placed in the above-mentioned clean room (3) is located in the center, and suction fans (5) are arranged on both sides, and the polluted air in the reagent storage room (2) is sucked into the clean room through the suction fan, and passed through the filter column ( 4) The circulation structure discharged to the lower end after purification, the disadvantage is that part of the air purified by the filter column (4) is sucked by the suction fan (5) again, and the purification efficiency is low, especially when the quality of harmful gas is greater than the air quality, the suction fan (5) Pollution gas cannot be inhaled completely, and part of it remains at the lower end of the reagent storage room (2). When the user or implementer opens the reagent cabinet door, there is a problem that the air inside the reagent storage room (2) directly flows into the room

[0007] On the other hand, as another prior art solution to solve the problems brought by the above-mentioned prior art, such as Korean Patent No. 10-0776563, the air inside the reagent cabinet is also repeatedly circulated in a closed space and purified with a filter column. way, such as Figure 8 , 9 As shown, the fully enclosed self-circulating harmful substance storage box (1″) is divided into a reagent storage room (2) and a clean room (3) by a side partition (8), and multiple filter columns are arranged in the clean room (3) (4), several filter columns are staggered and superimposed on each other, and a suction fan (5) is installed on the upper pipeline (7a) connecting the reagent storage room (2) and the clean room (3). Columns are staggered and superimposed, occupying a relatively large space in the clean room, and relatively speaking, the space of the storage room is reduced, which limits the concept of space saving and flexible use of space and the storage capacity of the reagent cabinet. The multi-layer filter columns (4) are staggered and stacked for To achieve the complete circulation of the internal air, the horsepower of the suction fan must be increased, thereby increasing related costs such as electricity charges and increasing noise, especially the position of the lower pipeline (7) is remote from the clean room (3), and the circulation efficiency is low. When opening the door of the reagent cabinet, the lower right side of the reagent cabinet with weak internal circulation will flow the polluted gas into the air.

[0008] Moreover, the traditional filter column (4) is simply composed of multiple filter columns, which cannot effectively purify and neutralize various volatile organic compounds, stench, smoke and other harmful gases generated in the reagent cabinet.
