Detailed description of the invention
Purification of chemical waste gas system, including air collector 1, scrubbing tower 2, heat exchanger and exhaustor 10, air collector 1 arranges waste gas
Pipe 11 is to collect waste gas, and air collector 1 bottom arranges discharging valve 12 and exhaust-valve 13, air collector 1 upper end installation of relief valve, air collector
The air inlet 20 of 1 connection scrubbing tower 2, scrubbing tower 2 gas outlet 22 connects tubular heat exchanger 6, in pipe heat exchanger connection freezing
Water pipe 14 and freezing downcomer 15, tubular heat exchanger 6 connects aerofluxus surge tank 7, and aerofluxus surge tank 7 connects activated carbon adsorption dress
Putting 8, absorbent charcoal adsorber 8 connects exhaustor 10 by air-introduced machine 9,
Scrubbing tower 2 liquid outlet 21 connects absorbing liquid surge tank 4 by detergent circulator 3, and absorbing liquid surge tank 4 top is even
Logical tubular heat exchanger 6, absorbing liquid surge tank 4 connects plate type heat exchanger 5, plate type heat exchanger 5 communication loop upper hose 17 and following
Ring downcomer 16, plate type heat exchanger 5 connects scrubbing tower 2 inlet 23, and inlet 23 also connects water inlet pipe 19, absorbing liquid surge tank
4 upper ends arrange breather valve 18, and breather valve 18 connects aerofluxus surge tank 7, and breather valve 18 can prevent pressure mistake in absorbing liquid surge tank 4
High.
The technological process of this specific embodiment: air collector 1 collects chemical emission by flue gas leading 11, and waste gas is from scrubbing tower 2
The air inlet 20 of bottom enters scrubbing tower 2, scrubbing tower 2 spray washing absorb, and cleaning mixture is by the inlet 23 on scrubbing tower 2 top
Enter, cleaning mixture counter flow washing purify waste gas, the harmful components in waste gas be washed liquid absorb, cleaning mixture be organic solvent or
Water, the gas outlet 22 of the scrubbed tower of waste gas 2 enters tubular heat exchanger 6, and the harmful components not absorbed on a small quantity in waste gas are passed through
Tubular heat exchanger 6 condenses collection further, tubular heat exchanger 6 act as the degree of depth cooling be not washed have on a small quantity
Evil waste gas, cooling medium is chilled water, through air inducing after then waste gas is adsorbed by aerofluxus surge tank 7 and absorbent charcoal adsorber 8
Machine 9 is by exhaustor 10 high altitude discharge；In scrubbing tower 2, the liquid outlet 21 bottom the scrubbed tower of cleaning mixture 2 enters detergent circulator
3, cleaning mixture scrubbed liquid circulating pump 3 enters plate type heat exchanger 5, enters scrubbing tower 2 through plate type heat exchanger 5 from inlet 23 and follows
Ring absorbs, and cleaning mixture absorbs finite concentration and squeezed in absorbing liquid surge tank 4 by detergent circulator 3, and plate type heat exchanger 5 acts on
For cooling circulation liquid, with reasonable energy utilization, finally enter scrubbing tower 2 and recycle, liquid in absorbing liquid surge tank 4, can depend on
Reclaim according to analysis result or enter sewerage and process qualified discharge.
Finally should be noted that: it is only limited by above example in order to the technical solution of the utility model to be described
System；Although being described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the field should
