Description
Technical field
The utility model relates to a kind of nickel shot dissolution reactor gas extraction system of chemical industry.
Background technology
The nickel shot dissolution reactor is a kind of reactor of all being participated in mutually by solid, liquid, gas.Because the generation of the gas of hydrogen, acid gas, water vapour and other foul smelling volatile flavors is arranged in the course of reaction, accumulate in the workshop for avoiding hydrogen, eliminate hydrogen explosion hidden danger, normally used is open reactor, carries out in the place preferably at ventilation condition; Like this, certainly will cause the gas of acid gas, water vapour and other foul smelling volatile flavors directly to enter atmosphere, contaminated air; Simultaneously, thermal loss is also very big in the course of reaction, causes the energy consumption of LU weight nickel to increase.
Summary of the invention
The utility model technical problem to be solved provides a kind of orderly discharging of hydric safe that reaction is produced, and acid gas and foul odour gas use alkali lye to reclaim, and water vapour obtains the nickel shot dissolution reactor gas extraction system of condensation reuse.
The utility model solves the technical scheme that its technical problem adopted: a kind of nickel shot dissolution reactor gas extraction system; Said scrubbing tower top is connected with Venturi tube through pipeline, and said wash tower bottoms end is connected with the wash cycle groove through pipeline, is filled with Pall ring in the said scrubbing tower; Be provided with the drip washing shower nozzle in the said scrubbing tower; Said wash cycle groove is connected with the cleaning circulation pump left side through pipeline, and said cleaning circulation pump right side is connected with the drip washing shower nozzle through pipeline, and said wash cycle groove is provided with second exhaust outlet and is connected with Venturi tube through pipeline; Said scrubbing tower is connected with graphite condenser through pipeline; The other reactor that is provided with of said graphite condenser, said reactor head are provided with first exhaust outlet and are connected with the graphite condenser bottom through pipeline, and said reactor head is provided with emergent exhaust outlet and is connected with emergent water sealed tank through pipeline; Said reactor is provided with refluxing opening, and said refluxing opening is connected with graphite condenser through pipeline.
After adopting said structure; Be characterized in: under the normal reaction situation; Gas gets into graphite condenser from first exhaust outlet through pipeline; Emergent exhaust outlet just just works under the emergency when reactor pressure surpasses 50 centimeter water columns, and at this moment reactor tail gas also gets into water sealed tank from emergent exhaust outlet through piping and directly enters atmosphere in through the exhaust outlet discharging.
At first through the graphite condenser cooling, the water vapour that includes and a part of acid gas obtain a part of sour water through supercooling to gas, get into reactor through pipeline from refluxing opening in the reactor; Other hydrogen, foul gas and remaining a part of acid gas get into scrubbing tower; In the washing absorption of scrubbing tower, make acid gas and foul gas and alkali reaction in the gas, only surplus hydrogen in the last gas through sig water and Pall ring; Draw the entering Venturi tube from scrubbing tower top; Mix diluent gas, safety dumping atmosphere with a large amount of air of blower fan input.
The negative pressure of Venturi tube generation here is the draft of whole gas blow-off system; Make acid gas, water vapour in the tail gas obtain reasonable reuse; Foul gas and few part acid gas obtain absorption, have eliminated the pollution to environment, and flammable hydrogen obtains safe and orderly discharging.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. scrubbing tower, 2. Venturi tube, 3. washing cannelure, 4.
