Description
Technical field
The utility model belongs to technical field of chemical, relates in particular to a kind of protochloride Tie Tong chlorine absorption plant.
Background technology
At present, the chlorine absorption unit that China adopts all is filler absorption patterns, and filler is housed in the tower, and frerrous chloride is from top spray, and chlorine is sucked by blower fan from the bottom, and chlorine and solution of ferrous chloride react absorption in filler.Though this equipment is simple in structure, chlorine content is greater than 20mg/m in the exhaust emissions
3, air has been caused pollution, in course of reaction, the solution reaction temperature might rise to more than 100 ℃, equipment is had big damage effect, and the absorption efficiency of chlorine is low in entire reaction course.
Summary of the invention
The technical problem that the utility model solved provides a kind of simple in structure just at deficiency of the prior art, and the absorption efficiency height is to the harmless protochloride of equipment Tie Tong chlorine absorption plant.
The technical solution of the utility model is as follows: a kind of protochloride Tie Tong chlorine absorption plant, it is characterized in that this absorption plant comprises chlorine cylinder, Chlorine Buffer Vessel, main absorption system and secondary absorption system, described main absorption system comprises main absorption cell and the main absorbent recirculation pump that is used to deposit reaction liquid, and described secondary absorption system comprises secondary absorption cell and secondary absorbent recirculation pump.
As a kind of improvement of the present utility model, described main absorption system also comprises the plate type heat exchanger that cools off reaction liquid.
As a kind of improvement of the present utility model, described main absorption system also comprises the venturi-type eductors that gas is absorbed and mixes.
As a kind of improvement of the present utility model, described secondary absorption system also comprises the plate type heat exchanger that cools off reaction liquid.
As a kind of improvement of the present utility model, described secondary absorption system also comprises the venturi-type eductors that gas is absorbed and mixes.
With respect to prior art, the utlity model has following advantage, this absorption plant is simple in structure, to the absorption efficiency height of chlorine, and the use of plate type heat exchanger, can reduce the temperature of reaction liquid, reduces the infringement to equipment.
Description of drawings
Fig. 1 is an entire reaction apparatus structure schematic diagram;
Among the figure: 1 is chlorine cylinder, and 2 is Chlorine Buffer Vessel, and 3 is main absorption system,
3-1 is main absorption cell, and 3-2 is main absorbent recirculation pump, and 3-3 is a plate type heat exchanger,
3-4 is a venturi-type eductors, and 4 is secondary absorption system, and 4-1 is secondary absorption cell,
4-2 is secondary absorbent recirculation pump, and 4-3 is a plate type heat exchanger, and 4-4 is a venturi-type eductors.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, can see that whole absorption plant comprises chlorine cylinder 1, Chlorine Buffer Vessel 2, main absorption system 3 and secondary absorption system 4, main absorption system 3 comprises main absorption cell 3-1 and the main absorbent recirculation pump 3-2 that is used to deposit reaction liquid, the plate type heat exchanger 3-3 of cooling reaction liquid, the venturi-type eductors 3-4 that gas is absorbed and mixes; Secondary absorption system 4 comprises the plate type heat exchanger 4-3 of secondary absorption cell 4-1 and secondary absorbent recirculation pump 4-2 cooling reaction liquid, the venturi-type eductors 4-4 that gas is absorbed and mixes.
Entire reaction technology is as follows, main, insert the frerrous chloride about 9 tons in the secondary absorption cell, open main, secondary absorption cell circulating pump, open the master, secondary absorption cell heat exchanger cooling water valve, open chlorine cylinder 1 valve, open steel cylinder trickle valve, regulate chlorine flowrate to correct position, solution of ferrous chloride in the main absorption cell 3-1 enters plate type heat exchanger 3-3 through main absorbent recirculation pump 3-2 and cools off, after being cooled to 50～60 ℃ to venturi-type eductors 3-4, liquid can produce negative pressure when venturi-type eductors ejects, chlorine is absorbed, with react after frerrous chloride liquid mixes, reacted liquid sprays back in the main absorption cell 3-1 again, and the chlorine inlet in this process in the venturi-type eductors can produce stronger negative pressure, the chlorine of gasification in the liquid chlorine cylinder 1 is absorbed among the venturi-type eductors 3-4 mix with frerrous chloride, spray into together in the solution of ferrous chloride in the main absorption cell 3-1, the generation ferric trichloride reacts; The unreacted chlorine of part overflows from the chlorine overfall of main absorption cell top, enter among the venturi-type eductors 4-4 of secondary absorption cell 4-1 top, chlorine enters, the more weak negative pressure of the same generation of the venturi-type eductors 4-4 of secondary absorption cell 4-1, suck unreacted chlorine of part and the interior frerrous chloride reaction of secondary absorption cell in the main absorption cell, chlorine is after twice absorption like this, and the chlorine absorption efficiency reaches 99.99%; Behind the complete oxidized formation ferric trichloride of the frerrous chloride in the main absorption cell 3-1, stop logical chlorine, solution of ferrous chloride in the secondary absorption cell 4-1 is transferred to main absorption cell 3-1, enter fresh frerrous chloride again in the secondary absorption cell 4-1, continue logical chlorine then, in secondary absorption cell, keep fresh state so always, guaranteed the absorption fully of chlorine.Above-mentioned whole process has realized protochloride Tie Tong chlorine, and logical chlorine efficient height, reaches 99.99%, and to not infringement of equipment.
Above embodiment is the comparatively complete embodiment of the utility model; be not to be used for limiting protection domain of the present utility model; if its technical scheme is identical with technical scheme in the utility model claims or carry out simple substitution, all belong to protection domain of the present utility model.
