Description
Technical field
The utility model relates to a kind of thionizer, especially relates to a kind of thionizer of deviating from hydrogen sulfide in the bittern.
Background technology
China is that the first in the world is produced salt big country, and annual salt output reaches 5,000 ten thousand tons, and wherein well mine salt output accounts for more than 1/3rd.With respect to sea salt, lake salt, well mine salt has quality better, is not subjected to advantages such as the seasonal effect and the area that occupies cultivated land lack, and is the direction of giving priority to of China's salt industry.Bittern is as the basic salt manufacturing raw material of well mine salt, and the quality of its quality is directly connected to well mine salt vacuum salt production cost and finished product salt quality.And in the bittern of existing nearly 1/3rd output of China, contain sulfide impurities to some extent, wherein more than 96% H
2S.These sulfide impurities long-term corrosions are adopted defeated halogen and salt making equipment, and the finished product salt quality caused have a strong impact on, and make finished product salt phenomenons such as general red, yellowing occur, to the mine adopt defeated halogen and the well mine salt vacuum process very harmful.Therefore, must be to the H particularly of the sulfide in the bittern
2S carries out purifying treatment, and this is the important content that bittern purifying is handled.
H in the purifying treatment bittern
2S has chemical treatment and two kinds of basic technology modes of physical treatment.The bittern chemical desulfurization is handled, be exactly in bittern, to throw in the bittern purifying medicine, with sulfide in the bittern mainly be H
2Chemical reaction takes place and generates precipitation in S, and then reaches H in the purifying treatment bittern by operations such as precipitate and separate and pulp water processing
2The purpose of S, this method sweetening effectiveness is better, but has the big shortcomings of subsequent disposal operation technical difficulty such as processing cost height, solid-liquid separation and pulp water processing, makes it limited in industrial use.
Bittern physics desulfurization treatment process generally is to adopt bittern desulfurizers such as branch frame, waterfall, solarization halogen plate, utilizes gravity that bittern is installed under spontaneous currents along these from eminence, makes the H in the bittern
2S is volatilized, but can't reach the index request that the brine depth desulfurization is handled, exist simultaneously floor space big, to the heavy-polluted shortcoming of surrounding enviroment.
The utility model content
The purpose of this utility model be to overcome the shortcoming of above-mentioned prior art and provide a kind of simple in structure, floor space is little, energy consumption is low, pollution is little, the desulfurizer of processing ease, bittern that sweetening effectiveness is good.
The purpose of this utility model is achieved in that
A kind of bittern desorb thionizer comprises tower body, is provided with gas passage at cat head, is provided with liquid outlet opening at the bottom of tower, wherein is divided into mutual isolated desorb desulfurization zone and off-gas treatment section from bottom to top successively in tower body inside; Epimere at the desorb desulfurization zone is provided with the bittern sparger that is communicated with bittern collection device outside the tower body, and the stage casing is provided with desorb desulfurization filler, and hypomere is provided with the vent-pipe that links to each other with external blower; Epimere in off-gas treatment section is provided with the treatment solution sparger that is communicated with tower body external treatment flow container, and the stage casing is provided with the off gas treatment filler, and hypomere is set to the waste gas chamber, and wherein, the waste gas chamber is connected with the epimere space of desorb desulfurization zone by pipeline.
Wherein, described bittern collection device can be the device of centralized collection bittern, as the bittern jar, or sub-salt well; Further improving is that described treatment solution sparger is communicated with the alkali liquid tank and the acid solution jar of tower body outside respectively.
Principle of work of the present utility model is as follows: the former halogen of sulfur-bearing from the bittern collection device comes, advance
Go in the bittern sparger, bittern is evenly splashed under the effect of gravity in the desorb desulfurization filler, simultaneously, gas blower blasts pressurized air, enters from bottom to top in the desorb desulfurization filler through vent-pipe, realizes maximized gas-to-liquid contact with former halogen at filling surface, finish gas-liquid mass transfer, utilize pressurized air that dissolved gases in the bittern is forced to blow out, simultaneously, be dissolved in the O in the bittern
2To H
2S carries out oxidation, and with the generation elemental sulfur of low price sulphide, elemental sulfur can exist in solution with 9 kinds of different crystallized forms, and they do not dissolve basically, is convenient to separate; The bittern desulfurize discharge gas enters the off-gas treatment section bottom by pipeline from desorb desulfurization zone top, pass through the off gas treatment filler from bottom to up, meanwhile, circulation alkali liquor is input into into the off-gas treatment section top by pump, pass through the off gas treatment filler from top to bottom through off gas treatment alkali lye sparger, desulfurize discharge gas and circulation alkali liquor are finished the gas-liquid mass transfer treating processes at off gas treatment filler filling surface, qualified discharge waste gas after the processing is discharged from cat head, purification halogen after the desulfurization is discharged at the bottom of tower, finishes bittern desorb sulfur removal technology process.
In addition, thionizer needs regular (being generally 30 days) that the adherent landwaste of desorb desulfurization filling surface is carried out cleanup acid treatment, when needing to handle, pickle solution is from the off-gas treatment section top, pass through the off gas treatment filler from top to bottom successively through off gas treatment alkali lye sparger, through the waste gas chamber of off-gas treatment section bottom, enter in the desorb desulfurization zone then, enter pickling tank and recycle through discharging at the bottom of the tower behind bittern sparger, the desorb desulfurization filler successively again by pipeline.
Adopt the utility model that bittern is carried out desulfurization, have following advantage:
(1) the bittern sweetening effectiveness is good: can be with H in the bittern
2S content is reduced to below the 0.5mg/L from 200mg/L.
(2) energy consumption is low, and processing cost is low: energy consumption is the gas blower power consumption only, is generally 0.45KWh/m
3Bittern; With H in the bittern
2S content is 0.90 yuan/m from the unit running cost that 200mg/L reduces to below the 0.5mg/L
3Bittern has only 2.50 yuan/m of chemical treatment method
336% of the processed in units cost of bittern.
(3) environmental protection: because the bittern desulfurize discharge gas realized qualified discharge, also can impassioned waste lye and pickling waste waters inject waste and old well chamber, make this bittern desorb thionizer become the environmental protecting device of environmentally safe.
(4) floor space is little: processing power is 100m
3Bittern desorb thionizer and the affiliated facility floor space of/h are about 3000m
2, the circulated aeration tank blowing out device that reaches equal processing power reduces land area 5000m
2More than.
