Hydrogen chloride gas by circulating gas pipe 52 enter storage liner 2 middle and lower part so that volatilization hydrogen chloride gas incorporate again
Into hydrochloric acid, the volatilization of hydrochloric acid is advantageously reduced, may make hydrochloric acid storage safer;It is in static always in hydrochloric acid storage tank
When state, volatilizing because of intermittent spill in water of liquid nitrogen in annular liner 3 is nitrogen, so that between tank body 1 and storage liner 2
A large amount of nitrogen are saved bit by bit on the surface of water, and when nitrogen pressure constantly increases the pressure value for reaching pressure valve 57, pressure valve 57 is opened, nitrogen
Gas calms the anger plate 55 from the annular that venthole 56 enters temporary cavity 5 rapidly in upper plenum, plate 55 is so that annular is calmed the anger with overhead
The pressure moment of chamber increases, so that annular is calmed the anger, plate 55 is pushed rapidly, annular is calmed the anger under the hydrogen chloride gas of 55 lower section of plate
It is pressed onto circulating gas pipe 52, subsequent hydrogen chloride gas enters the middle and lower part of storage liner 2, so that the hydrogen chloride gas of volatilization is again
It is dissolved into hydrochloric acid, advantageously reduces the volatilization of hydrochloric acid;Meanwhile there is partial oxidation hydrogen to overflow from the cover 13 of tank mouth 11
Out, the hydrogen chloride gas of spilling passes through the sodium carbonate particle layer 141 on the inside of protective cover 14, hydrogen chloride gas and sodium bicarbonate particle
Neutralization reaction occurs, avoids and volatilizees with mordant hydrogen chloride gas, meanwhile, hydrogen chloride gas is anti-with sodium bicarbonate particle
Should can radiate so that cover 13 and protective cover 14 generate heat, and the nitrogen in temporary cavity 5 be it is lasting by venthole 58 slowly
It is overflowed to 14 inside vacancy of protective cover, because nitrogen is just evaporated by liquid nitrogen, so that nitrogen is also in low-temperature condition, it is low
The nitrogen of temperature can take away the heat on protective cover 14 and cover 13 when passing through protective cover 14, make protective cover 14 and cover 13
It is maintained in low temperature environment, avoids hydrochloric acid and volatilize spilling because temperature is excessively high, be conducive to hydrochloric acid secure storage;And sodium carbonate
The outside of granulosa 141 is provided with layer of silica gel 142, and sodium carbonate and hydrogen chloride gas precursor reactant generate water, so that layer of silica gel 142 absorbs
The water generated is reacted, the surrounding that the water that sodium carbonate and hydrogen chloride gas precursor reactant generate flows to hydrochloric acid storage tank is avoided, is conducive to
Keep the cleaning of hydrochloric acid storage tank;Wherein, silica gel does not react at normal temperature with sodium carbonate and hydrochloric acid.
More than, it is illustrated about one embodiment of the present invention, but the present invention is not limited to the above embodiments, not
Various changes are able to carry out in the range of disengaging present subject matter.
Industrial applicibility
According to the present invention, tank mouth is protected by protective cover, drops low-volatile hydrogen chloride gas corrosion harmfulness;By with watertight
It is packaged with the storage liner of hydrochloric acid, avoids the concentration of hydrochloric acid of leakage excessive;By arranging on the outside of storage liner equipped with liquid nitrogen
Annular liner cools down to hydrochloric acid, reduces hydrochloric acid volatilization;Hydrochloric acid is stirred by stirring module, it is equal to make to store hydrochloric acid temperature in liner
Weighing apparatus, it is excessively high to avoid local hydrochloric acid temperature, reduces hydrochloric acid volatilization, improves hydrochloric acid storage security;Therefore hydrochloric acid storage
Tank is useful in hydrochloric acid technical field of memory.
