Abstract
The utility model relates to a gas emergency absorption system, in particular to a dry emergency absorption system of aluminum fluoride, which comprises an emergency absorption air inlet pipeline and an emergency absorption air outlet pipeline. A draught fan is arranged on the emergency absorption air outlet pipeline. The dry emergency absorption system of the aluminum fluoride is characterized in that a first level absorption tower and a second level absorption tower are sequentially arranged on the emergency absorption air inlet pipeline and the emergency absorption air outlet pipeline. A first level circulating pump and a first level circulating alkali tank are sequentially connected between the top and the bottom outside the first absorption tower. A second level circulating pump and a second level circulating alkali tank are sequentially connected between the top and the bottom outside the second level absorption tower. The dry emergency absorption system of the aluminum fluoride is simple in operation, enables spilled hydrogen fluoride gas to be contacted with spraying alkaline water flowing reversely completely to achieve the purposes of cooling, purification and absorption, and has no pollution to environment.
Description
Technical field
The utility model relates to the urgent absorption system of a kind of gas, is specifically related to the urgent absorption system of a kind of aluminum fluoride by dry process.
Background technology
At present, in the production process of dry process aluminum fluoride, need carry out the preparation feedback of hydrogen fluoride gas earlier, but if hydrogen fluoride preparation feedback follow-up system fault takes place, can cause in the hydrogen fluoride reaction stove a large amount of hydrogen fluoride gas normally not discharge, excessive under positive pressure environment be impacted.Therefore, need the urgent absorption system of a cover hydrogen fluoride gas, hydrogen fluoride gas is collected, avoid environment is polluted.
The utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: provide a kind of aluminum fluoride by dry process urgent absorption system, can play the effect of urgent absorption to excessive hydrogen fluoride gas.
The urgent absorption system of aluminum fluoride by dry process described in the utility model, comprise urgent absorption admission line and the urgent outlet pipe that absorbs, the urgent outlet pipe that absorbs is provided with air-introduced machine, the urgent absorption on admission line and the urgent absorption outlet pipe is disposed with first grade absorption tower and two-level absorption tower, be connected with one-level circulating pump and one-level circulation alkali groove successively by pipeline between outer top of first grade absorption tower and the bottom, be connected with secondary circulating pump and secondary circulation alkali groove successively by pipeline between outer top of two-level absorption tower and the bottom.
Wherein, preferably be provided with demister between two-level absorption tower and the air-introduced machine, can be to better collection of playing of gas and clean-up effect.
The course of work of the present utility model is as follows: hydrogen fluoride gas successively enters first grade absorption tower and two-level absorption tower through the urgent admission line that absorbs, with reverse flow through one-level circulating pump and secondary circulating pump make the spray buck contact, to first grade absorption tower and two-level absorption tower circulation pouring, hydrogen fluoride gas is absorbed in the spray buck, flows in one-level circulation alkali groove and the secondary circulation alkali groove.Under the effect of air-introduced machine, purify back gas and discharge from urgent absorption outlet pipe through demister.All be absorbed in the buck through the urgent hydrogen fluoride gas that absorbs, can not exert an influence to environment again.
The beneficial effect that the utility model had is: simple to operate, excessive hydrogen fluoride gas fully can be contacted with the spray buck of reverse flow, and reach the purpose of cooling, purification, absorption, can not pollute environment again.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1, promptly absorb admission line 2, first grade absorption tower 3, two-level absorption tower 4, demister 5, air-introduced machine 6, promptly absorb outlet pipe 7, secondary circulating pump 8, secondary circulation alkali groove 9, one-level circulation alkali groove 10, one-level circulating pump.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the urgent absorption system of aluminum fluoride by dry process described in the utility model, comprise urgent absorption admission line 1 and the urgent outlet pipe 6 that absorbs, the urgent outlet pipe 6 that absorbs is provided with air-introduced machine 5, the urgent absorption on admission line 1 and the urgent absorption outlet pipe 6 is disposed with first grade absorption tower 2 and two-level absorption tower 3, be connected with one-level circulating pump 10 and one-level circulation alkali groove 9 successively by pipeline between first grade absorption tower 2 outer tops and the bottom, be connected with secondary circulating pump 7 and secondary circulation alkali groove 8 successively by pipeline between two-level absorption tower 3 outer tops and the bottom.
Wherein, be provided with demister 4 between two-level absorption tower 3 and the air-introduced machine 5, can be to better collection of playing of gas and clean-up effect.
The course of work of the present utility model is as follows: hydrogen fluoride gas successively enters first grade absorption tower 2 and two-level absorption tower 3 through the urgent admission line 1 that absorbs, with reverse flow through one-level circulating pump 10 and secondary circulating pump 7 make the spray buck contact, to first grade absorption tower 2 and two-level absorption tower 3 circulation pourings, hydrogen fluoride gas is absorbed in the spray buck, flows in one-level circulation alkali groove 9 and the secondary circulation alkali groove 8.Under the effect of air-introduced machine 5, purify back gas and discharge from urgent absorption outlet pipe 6 through demister 4.All be absorbed in the buck through the urgent hydrogen fluoride gas that absorbs, can not exert an influence to environment again.
The utility model is simple to operate, excessive hydrogen fluoride gas fully can be contacted with the spray buck of reverse flow, reaches the purpose of cooling, purification, absorption, can not pollute environment again.
