Description
Technical field
The utility model relates to a kind of hydrochloric acid full stripping system and device.
Background technology
Existing hydrochloric acid is resolved and is divided into azeotropic and resolves with complete solution and analyse in the prior art, and azeotropic is resolved and invested for a short time, and energy consumption is low, but the HCL major part is stayed in the azeotropic acid; The HCL utilization ratio is very low, and utilizes azeotropic acid circulation absorption can not reach balance, and this just makes a part of azeotropic s.t. difficult, and the hydrochloric acid full stripping technology is exactly a deutero-under this background; At present, the hydrochloric acid full stripping technology has pressure differential method and adds the broken agent method of boiling, but the pressure differential method energy consumption is too high, and is superseded fully; Adding the agent method of spending money all is in hydrochloric acid, to add calcium chloride to destroy the hydrochloric acid constant boiling point, improves the volatility of HCL, existing owing to added calcium chloride; Corrosion aggravation, and the easy crystallization of calcium chloride, equipment is prone to fouling; So Calcium Chloride Method is had relatively high expectations to operational conditions such as temperature, need be incubated, sealing need be carried out special processing.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes prior art; A kind of hydrochloric acid full stripping system and device is provided; The utility model solves the technical scheme that its technical problem adopted: the structure of the utility model comprises resolver, blows the chlorine tower, diluted acid pump, gas blower, sulphuric acid concentration device, waste water condensing surface, level tank, concentrated acid pump, concentrated acid water cooler, absorption system, vacuum system, sour water relief outlet, it is characterized in that the bottom of resolver is connected with the side of blowing the chlorine tower, and the top of resolver is provided with the HCL pneumatic outlet; Following and the gas blower that blows the chlorine tower is connected; The top of blowing the chlorine tower is provided with outlet and links to each other with absorption system, blows the chlorine tower bottom and is connected with the diluted acid pump, and the diluted acid pump is connected with the side of sulphuric acid concentration device; The bottom of sulphuric acid concentration device is connected with level tank; The sulphuric acid concentration device the top link to each other with the waste water condensing surface, the waste water condensing surface links to each other with the sour water relief outlet with vacuum system respectively, level tank bottom links to each other with the concentrated acid pump; The concentrated acid pump is connected with the concentrated acid water cooler, and the outlet of concentrated acid water cooler links to each other with 96% sulfuric acid storage tank.
Principle of work: the utility model advances the vitriolic acid flux and the hydrochloric acid flow of resolver to be regulated through transmitter and flow director; And regulate in proportion; Blowing the liquid level of green tower regulates through fluid level transmitter and fluid level controller automatically; Concentrator pressure is regulated through pressure unit and pressure controller, and the thickener temperature is regulated through temperature transmitter and unit, and the liquid level of level tank is regulated through fluid level transmitter and fluid level controller.Principle of work is that 96% sulfuric acid gets into the resolver packing section from resolver top; Contact in packing section with the HCL gas that rises on the resolver bottom; With the moisture absorption in the HCL gas, the dry HCL gas that is absorbed behind the moisture goes out resolution system from the resolver top, and hydrochloric acid gets into resolver from the resolver middle part; In the resolver bottom through after being arranged on inner overflow Mixed Weir of resolver and sulfuric acid and carrying out thorough mixing; HCL gas rises to packing section from the resolver bottom, and in the resolver bottom, sulfuric acid is not less than 65% by the dilution of the water in hydrochloric acid back concentration and goes out resolver; Blow the air of chlorine tower bottom through entering behind the gas blower and come out to get into reverse contact of the packing section of dilute sulphuric acid in blowing the chlorine tower of blowing the chlorine tower from the resolver bottom from blowing chlorine tower top; Chloride less than 0.5% chlorine stripping with remaining in the dilute sulphuric acid, the chlorine behind the stripping gets into absorption system, and the dilute sulphuric acid after the dechlorination gets into thickener top through the diluted acid pump; Behind the filler on thickener top, get into the bottom of thickener; Moisture is gone out from the evaporated on top of thickener under positive empty condition through heating (thermal source can be electricity, steam or thermal oil) in the bottom, the moisture that comes out from the top of thickener contains acid 0.5%, gets into the waste water condensing surface; The waste water condensator outlet links to each other with vacuum system; The lane acid 96% of coming out from thickener bottom gets into level tank, the concentrated acid in the level tank through the concentrated acid pump get into remove the concentrated acid storage tank behind the concentrated acid water cooler after circulation get into resolver top, also can directly use going 65% diluted acid storage tank then 65% dilute sulphuric acid to be delivered to phosphate fertilizer factory after the 65% diluted acid dechlorination.
The beneficial effect of the utility model is; The utility model is easy to operate, energy consumption is little, resolve HCL gas part does not need heating; And get into concentration systems after the dilute sulphuric acid that resolution system comes out self also is elevated to certain temperature, compare existing complete solution and analyse technology saving steam more than 50%.
