The device can be used for effectively carrying out absorption and emptying separation treatment on the flammable and explosive gases produced in the hydrochloric acid intermediate tank, so that the potential safety hazard caused by the flammable and explosive gases existing in a production process of hydrochloric acid is completely eliminated.
Description
Technical field
The utility model relates to the safety equipment in chemical process, is specifically related to a kind of device of removing the inflammable and explosive property of hydrochloric acid medial launder gas.
Background technology
Typical hydrochloric acid synthesis technique was hydrogen production technique, excess hydrogen enters film-falling absorption tower together with hydrogen chloride gas, the hydrochloric acid that hydrogenchloride is formed by water absorption can be carried hydrogen partial secretly and enter hydrochloric acid medial launder, when hydrochloric acid medial launder goes out acid, along with the vacuum tightness in the decline sealing hydrochloric acid medial launder of hydrochloric acid liquid level can rise, cause partial oxidation hydrogen to enter hydrochloric acid medial launder, enrichment formation Gas Mixtures Containing Hydrogen without absorbing directly with excess hydrogen, this has just caused potential safety hazard in hydrochloric acid production process.
At present hydrochloric acid is produced pipeline and is generally PVC material, easily produces static and electric discharge when hydrochloric acid flows in pvc pipe road, abnormally dangerous this mixed gas existing in above-mentioned hydrochloric acid medial launder, has the hidden danger of hydrochloric acid medial launder blast.Therefore, effectively removing the Gas Mixtures Containing Hydrogen in hydrochloric acid medial launder, is the key that realizes the safe operation of hydrochloric acid synthesis system.
Utility model content
The purpose of this utility model is for the problems referred to above, a kind of simple in structure, convenient operation is provided, can efficiently removes the device of the inflammable and explosive property of hydrochloric acid medial launder gas.
For reaching above-mentioned technique effect, the utility model adopts following technical scheme: a kind of device of removing the inflammable and explosive property of hydrochloric acid medial launder gas, comprise water flow jet vacuum, liquid seal can, circulation liquid bath and recycle liquid pump, the gas inlet of water flow jet vacuum is communicated with by mixed gas pipeline with hydrochloric acid medial launder top, the liquid inlet of water flow jet vacuum is communicated with recycle liquid pump by absorbing waterpipe, the bottom of water flow jet vacuum is communicated with by lower liquid pipe with liquid seal can top, liquid seal can top is also provided with exhaust pipe, liquid seal can bottom is by absorbing liquid pipeline communication circulation liquid bath top under water, circulation liquid bath bottom and recycle liquid pump pipeline connection.
Preferably, described lower liquid pipe and exhaust pipe are provided with telescopic joint.
Preferably, described exhaust pipe exit is provided with spark arrester.
Preferably, the pipeline that described circulation liquid bath is communicated with recycle liquid pump is provided with diaphragm valve, on described absorption waterpipe, near recycle liquid pump one side, is provided with diaphragm valve.
Preferably, the device of the inflammable and explosive property of described removal hydrochloric acid medial launder gas also comprises nitrogen replacement pipeline and controls ball valve, nitrogen replacement pipeline and control ball valve connection hydrochloric acid medial launder top.
The beneficial effects of the utility model:
Recycle liquid pump of the present utility model is constantly manufactured vacuum by absorbing waterpipe toward water flow jet vacuum delivery cycle liquid, and under the configuration downwards of aqueous stream injectors bottom vertical, liquid pipe and liquid seal can carry out gas-liquid separation.The nitrogen supplementary from hydrogenchloride, free chlorine, hydrogen and the displacement of hydrochloric acid medial launder enters absorption liquid circulation groove by absorbing liquid pipeline under water after water flow jet vacuum is absorbed by water, as absorption liquid recycle.Unabsorbed nitrogen and hydrogen are emptying by exhaust pipe and spark arrester, for preventing, because difference variation causes pipe deforming or breaks, telescopic joint being also installed on pipeline.The inflammable and explosive property gas that the utility model effectively produces hydrochloric acid medial launder has carried out effective absorption and emptying separating treatment, and the potential safety hazard causing because of flammable explosive gas existing in hydrochloric acid production process is eliminated completely.
