Abstract
The utility model belongs to the field of soda ash production and discloses a circulating treatment device for carbonized tower boiled liquid, which solves the problems of high cost and the loss of sodium bicarbonate during the treatment of conventional carbonized tower boiled liquid. The circulating treatment device for carbonized boiled liquid comprises an accident barrel, a waste liquid tank, a heat exchanger, a distillation tower, a condenser, an absorber, an ammonia mother liquid barrel and a pump, wherein the accident barrel, the waste liquid tank and the inlet of a cooling liquid tube of the heat exchanger are connected in sequence through a pipeline, the outlet of the cooling liquid tube of the heat exchanger is connected with a feed opening at the top of the distillation tower though the pipeline, an exhaust opening at the top of the distillation tower is connected with the condenser, the absorber and the ammonia mother liquid barrel in sequence through the pipeline, the ammonia mother liquid barrel is connected with the pump and the absorber to form circulation, and a discharge port at the bottom of the distillation tower is connected with the inlet of a heating liquid tube of the heat exchanger. The utility model can greatly save steam and water for tower boiling, the ammonia in the carbonized tower boiled liquid can be recycled through ammonia steaming, and ammonia nitrogen in the tower boiled liquid after ammonia steaming through the distillation tower can reach emission standards.
Description
Technical field
The utility model belongs to the soda ash production field, relates to a kind of carbonization and boils tower liquid cyclic processing device.
Background technology
In the soda ash production process, carbonating tower is behind for some time system alkali, and the sodium bicarbonate that adheres on tower wall, cap, the cooling tube scabs influences ordinary production, therefore must boil tower and clean.Carbonating tower boils and has dissolved the sodium bicarbonate crystallization in the tower liquid after boiling the tower cleaning.It is a more unmanageable ring in the soda ash production process that tower liquid is boiled in carbonization always, and for a long time, producer all takes the directly measure of discharging mostly, has caused environmental pollution.At present indivedual producers reduce ammonia nitrogen by joining a water, carry out sewage disposal again, do making that the sewage disposal expense is higher like this, have caused the loss of sodium bicarbonate simultaneously.
Summary of the invention
The present invention boils the problem that tower liquid expense height and sodium bicarbonate when handling run off in order to solve existing carbonization, and provides a kind of carbonization to boil tower liquid cyclic processing device.
The utility model is achieved through the following technical solutions:
Tower liquid cyclic processing device is boiled in a kind of carbonization, comprise accident bucket, waste liquid tank, interchanger, distillation tower, condenser, resorber, ammonia mother vat, pump, wherein accident bucket, waste liquid tank, be connected successively by pipeline with the cooling liquid tube import of interchanger, the cooling liquid tube outlet of interchanger is connected by the opening for feed of pipeline with the distillation tower top, the distillation tower top vent is connected with condenser, resorber, ammonia mother vat successively by pipeline, the ammonia mother vat connects and composes circulation by pump and resorber, and the discharge port of distillation tower bottom is connected with the import of interchanger hydrothermal solution pipe.In use, the accident bucket is connected with the carbonating tower bottom, the outlet of interchanger hydrothermal solution pipe is connected with carbonating tower its top feed mouth, that comes out from carbonating tower bottom boils tower liquid, pass through accident bucket, waste liquid tank, interchanger successively by pipeline, enter the distillation tower distillation, in distillation tower, be expelled to interchanger from the distillation tower bottom after the ammonia still process, squeeze into carbonating tower by pump after the heat exchange, the gas that steams in the distillation tower behind condenser condenses water vapour, enters resorber earlier, mix with the mother liquor of sending here from the ammonia mother vat, absorb ammonia.Like this circulation treatment reaches the purpose of environmental protection.
The utility model compared with prior art has the following advantages:
(1) the light liquid distillation soft water temperature height of arranging by the condenser heat exchange, can significantly be saved steam.
(2) the used water of tower is boiled in saving.
(3) the ammoniacal liquor titre of boiling tower liquid in the distillation tower is about 30tt, by the recyclable ammonia that boils in the tower liquid of ammonia still process.
(4) but after distillation tower ammonia still process, boil the ammonia nitrogen qualified discharge of tower liquid.
(5) soft water is little to the corrosion of equipment, prolongs service life of equipment.
