Background technology
Laboratory has a lot of link in the course of the work and produces substantial amounts of toxic harmful exhaust gas.Such as sample pre-treatments link
By spent acid gas harmful produced by catalyst and strong acid effect during digestion (clearing up), in process of the test, chemical reaction produces
Acidity, alkalescence harmful gas and reagent self volatilized during depositing acid, alkali harmful gas etc..These waste gas are all
Laboratory worker can be caused huge injury, the most also surrounding enviroment can be caused pollution greatly, in addition real
Test room harmful exhaust the most mishandling, while causing laboratory environment to pollute, also can affect normal chemical reaction process,
Cause test data deviation, misalignment, even test failure.Harmful exhaust is not inhaled by the middle-size and small-size laboratory of the overwhelming majority
The harmless treatments such as receipts, neutralization, but directly arranged to outdoor by ventilating kitchen.Part uses laboratory exhaust gas absorption plant
Large-scale experiment room, its absorption plant be mostly one group of upright inside can the absorption tower of filler, harmful exhaust passes sequentially through and is filled with
The absorption tower of different absorbents is to remove corresponding harmful exhaust, and it is solid that its absorbent is mainly sodium hydroxide, calcium carbonate, paraffin etc.
Bluk recombination type absorbent.There is following problem in laboratory harmful exhaust processing means at present: one is to be not easy to install, make
With, mostly absorption plant is one group of absorption tower, and volume is big, take space, is not easy to install and use at laboratory internal；Two is device
Expensive, operating cost is high, should not be used in medium and small laboratory；Three is that major part need to be arranged on outdoor, pipeline length, power of fan be big,
Easily leak, noise is big, energy consumption is high；Four is because absorbent is solid, and during work, waste gas is from bottom to top by absorption tower, at air-flow and
After gravity and reaction under the effect of product, easily making absorbent caking, blocking gas circuit, cause gas to pass through to be obstructed, impact is inhaled
Produce effects really, even bearing operation, causes potential safety hazard；Five is that absorbing tower mouth is less and produced material is reacted in absorption
Form bulk, cause installing additional, to change absorbent relatively difficult, waste time and energy；Six be the situation of assimilation effect and absorbent whether
Well, it is impossible to directly display, need to extract absorbent inspection rear and can determine that, both wasted time and energy, and have impact on again the process of waste gas
Effect.Therefore, devise a kind of laboratory poisonous fume and absorb neutralization device, be not only simple in structure, inspect intuitively, and operate
Convenient, durable.
