Abstract
The utility model relates to a device for recycling dilute hydrochloric acid from tail gas containing hydrogen chloride gas. The device comprises a buffer tank, a water jet pump, a hydrochloric acid absorption tank, an acid-proof pump, a tail gas blower, a tail gas absorption tower, an alkali circulating pump and connection equipment, wherein except for the alkali circulating pump, all the devices are made of acid-proof material. As the dilute hydrochloric acid is recycled from the tail gas, and a hydrochloric acid absorption tower with a cooling device is not adopted, the equipment investment is reduced; and as the recycled dilute hydrochloric acid is completely used for industry, the investment is low, the environmental pollution is eliminated, and the hydrochloric acid is recycled.
Description
Technical field
The utility model relates to a kind of waste gas recovering device, relates in particular to a kind of device that from the waste gas of gas containing hydrogen chloride, reclaims hydrochloric acid.
Background technology
At present general salt acid-restoring plant adopts the hydrochloric acid absorption tower of band refrigerating unit, and its content that reclaims hydrochloric acid is 30%, and this device is owing to there is cooling system, and energy consumption is big; What the utility model adopted is hydrochloric acid absorption tower; The concentration that reclaims hydrochloric acid is 15～20%; Therefore do not need refrigerating unit, because the amount of the unabsorbed hydrogenchloride of the not high entering tail gas destruction of concentration tower reduces accordingly, reduced the consumption of tail gas destruction alkali simultaneously; And the salt that produces is also few, has played the effect of saving energy, lowering energy consumption and reducing pollutants discharge.
The utility model content
A kind of device that from contain hydrogen chloride emission, reclaims Hydrogen chloride of the utility model; What adopt is hydrochloric acid absorption tower, and the concentration that reclaims hydrochloric acid is 15～20%, does not therefore need refrigerating unit; While is owing to the amount that the not high entering tail gas of concentration destroys the unabsorbed hydrogenchloride of tower reduces accordingly; Reduced the consumption of tail gas destruction alkali, and the salt that produces is also few, has played the effect of saving energy, lowering energy consumption and reducing pollutants discharge.
The technical scheme that the utility model adopts is:
A kind of device that from the waste gas of gas containing hydrogen chloride, reclaims Hydrogen chloride comprises surge tank, water jet pump, hydrochloric acid tourie, acidproof recycle pump, tail gas absorber, alkali recycle pump, exhaust fan and connecting tube; It is characterized in that: cushion dashpot connects hydrochloric acid tourie and acid through vacuum pump in the reaction kettle, and sour tourie connects tail gas through blower fan and destroys tower, and tail gas destroys tower and is connected after-treatment system with the alkali recycle pump, and after-treatment system is connected with useless treatment system.
A kind of device that from the waste gas of gas containing hydrogen chloride, reclaims Hydrogen chloride; It is characterized in that surge tank, tourie, water jet pump, tail gas absorber are the PP material; Exhaust fan is the plastic fan of acid-and base-resisting, and the alkali recycle pump is common alkaline-resisting impeller pump, and acid is the F4 pump.
The utility model produces reaction kettle in reaction process hydrogen chloride gas circulates in surge tank, water jet pump to hydrochloric acid tourie through waste pipe and absorbs into Hydrogen chloride; The concentration of control Hydrogen chloride is 15～20%; After reaching concentration requirement diluted acid is put into the diluted acid storage tank; Add clear water again and continue to absorb into diluted acid, the spray alkali lye that a small amount of hydrogen chloride gas that does not absorb is fully supplied with the alkali recycle pump by exhaust fan suction tail gas destruction tower is neutralized into sodium chloride solution entering after-treatment system and carries out desalting treatment, and last waste water gets into Waste Water Treatment; Handle back up to standard discharging, after alkali lye reaches neutrality, prepare alkali lye again.
A kind of device that from the waste gas of gas containing hydrogen chloride, reclaims Hydrogen chloride of the utility model has simple to operately, and investment cost is economized, the characteristics that treatment effect is good, the effect that reached energy-conservation, consumption reduction, reduces discharging.
Description of drawings
Fig. 1, a kind of structural representation that from contain hydrogen chloride emission, reclaims the device of Hydrogen chloride of the utility model.
Embodiment
A kind of device that from the waste gas of gas containing hydrogen chloride, reclaims Hydrogen chloride of the utility model, embodiment is:
The tail gas that reaction is produced in the reaction kettle 1 under the draft of vacuum pump 3, gets into hydrochloric acid tourie 4 through surge tank; Vacuum pump 3 carries out cyclic spray through acid 5 and produces vacuum; The unabsorbed hydrogen chloride gas of hydrochloric acid tourie destroys tower 7 through blower fan 6 suction tail gas, alkali recycle pump 8 with alkali lye squeeze into the cat head spray downwards with in and hydrogen chloride gas, coagulate the gas emptying at last; The sodium chloride solution that the neutralization back produces gets into after-treatment system and goes desalination, and waste water gets into Waste Water Treatment.
When the concentration of hydrochloric acid in the hydrochloric acid tourie greater than 15% the time, can Hydrogen chloride be put into the Hydrogen chloride storage tank through bottom valve and supply other to use or sale with sour operation.The hydrochloric acid tourie is put and is added the tap water absorption that circulates again after the acid again.
When the concentration of the liquid caustic soda of alkali destruction tower is reduced to PH for neutrality, waste water is entered after-treatment system.
The volume of surge tank is no less than the volume of hydrochloric acid absorption tower, and the acid of making provision against emergencies down is unlikely to get into reaction kettle.
Claims (2)
1. a device and a technology that from the tail gas that contains hydrogenchloride, reclaims hydrochloric acid comprises surge tank, tourie, acid, water jet pump, tail gas absorber, alkali recycle pump, exhaust fan and connecting tube; It is characterized in that: surge tank connects hydrochloric acid tourie and acid through vacuum pump in the reaction kettle, and sour tourie connects tail gas through blower fan and destroys tower, and tail gas destroys tower and is connected after-treatment system with the alkali recycle pump, and after-treatment system is connected with useless treatment system.
2. a kind of device that from the waste gas of gas containing hydrogen chloride, reclaims Hydrogen chloride according to claim 1; It is characterized in that surge tank, tourie, water jet pump, tail gas absorber are the PP material; Exhaust fan is the plastic fan of acid-and base-resisting; The alkali recycle pump is common alkaline-resisting impeller pump, and acid is the F4 pump.
