Detailed description of the invention
A kind of for the accident chlorine treatment method in liquid chlorine production, comprise following content: mixed with the alkali lye of mass concentration 32% by production water, the mass concentration of alkali in liquid is made to be down to 15%, when liquid chlorine storage tank district or liquid chlorine package district chlorine leakage, by the mass concentration of above-mentioned alkali be 15% liquid deliver to liquid chlorine storage tank district, liquid chlorine package district, spray from top, absorb the chlorine leaked; When chlorine liquid chlorine storage tank district or liquid chlorine package district leak, the liquid under spray flows into recovery pond through trench; After the liquid level of recovery pond reaches setting liquid level, the liquid in recovery pond is delivered to liquid chlorine storage tank district or liquid chlorine package district and again utilize when there is chlorine leakage accident; After the clorox mass concentration index of liquid in recovery pond reaches setting value, by the Liquid transfer in recovery pond to clorox storage tank; When clorox tank level reaches 80%, the liquid in recovery pond is delivered to Sewage Disposal, process qualified after drain into sewage treatment plant.
The mass concentration of alkali lye is reduced, has both overcome and produced the deficiency that water absorbs chlorine, turn avoid the excessive harm to personnel health of accident chlorine treatment pond 32% concentration of lye.In present chlor-alkali data, major part says that the concentration of caustic soda absorbing chlorine is 20%, but the alkali lye of this concentration is after absorption chlorine, when effective chlorine is qualified in the clorox of production, crosses alkali number higher, causes the waste to caustic soda.Find through test of many times, the mass concentration of the absorption alkali lye of preparation is 15%, and in the clorox of production, effective chlorine is qualified, crosses alkali number also qualified.
As shown in Figure 1, production water lines 21 adds orifice flowmeter, and 32% alkali lye pipeline 20 adds orifice flowmeter, mixes, alkali lye mass concentration is adjusted to 15% in venturi 8.In the course of work, during chlorine gas leakage, liquid chlorine is run out of by leak point under the effect of high pressure, the chlorine gas concentration in external procedure district constantly increases in time, chlorine detection probe 3 detects that chlorine exceeds standard, send sound and light alarm, the signal of telecommunication is passed to centralized control system simultaneously, as chlorine gas leakage occurs in liquid chlorine storage tank district 2, spray motor-driven valve first motor-driven valve 9, second motor-driven valve 10, 3rd motor-driven valve 11, 5th motor-driven valve 13, 7th motor-driven valve 15 is opened, 6th motor-driven valve 14, 8th motor-driven valve 16, 11 motor-driven valve 19 cuts out, spray equipment 4 above liquid chlorine storage tank district 2 sprays, absorb chlorine, as liquid chlorine package district 1 reveals, spray motor-driven valve first motor-driven valve 9, second motor-driven valve 10, the 3rd motor-driven valve 11, the 5th motor-driven valve 13, the 6th motor-driven valve 14 are opened, 7th motor-driven valve 15, the 8th motor-driven valve the 16, the 11 motor-driven valve 19 are closed, spray equipment 4 above liquid chlorine package district 1 sprays, and absorbs chlorine.The alkali lye absorbed after chlorine flows into recovery pond 6 through trench 5, after recovery pond 6 liquid level reaches setting liquid level, when again there is chlorine leakage accident, recovery pump 7 starts, 8th motor-driven valve the 16, the 11 motor-driven valve 19 is opened, first motor-driven valve 9, second motor-driven valve 10, the 3rd motor-driven valve 11 are closed, and alkali lye enters in main pipe rail and sprays to liquid chlorine package district 1 or liquid chlorine storage tank district 2 again.
After the mass concentration index of the clorox in recovery pond 6 reaches setting value, open the 8th motor-driven valve 16, the 9th motor-driven valve 17, close the tenth motor-driven valve the 18, the 11 motor-driven valve 19, clorox is transported to clorox storage tank, for primary brine process refined brine and sell outward.When liquid level as clorox storage tank reaches 80%, open the 8th motor-driven valve 16, the tenth motor-driven valve 18, close the 11 motor-driven valve 19, the liquid in recovery pond 6 is delivered to Sewage Disposal, processes qualified Hou Pai garden sewage treatment plant.
In the utility model, can the concentration of long-range free adjustment preparation alkali lye by motor-driven valve, reach the concentration range needed for accident and flow, the utility model achieves systematization, automation remote controls.Add steam in 32% alkali lye pipeline 20, plant air purges, can effectively reduce corrosion of piping and crystallisation problems.Production water lines 21 is also directly connected with main pipe rail by pipeline and the 4th motor-driven valve 12, can directly pass into production water as required.Reuse pipeline corrosion-resistant trench 5 replaces, and absorbing liquid can be recycled, after concentration lower bound, export outer selling by rear pump.This system can carry out effective process to the chlorine leakage accident in liquid chlorine package district 1 and liquid chlorine storage tank district 2.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or equivalently to replace, does not all depart from essence and the scope of technical solutions of the utility model.
