Description
Technical field
The utility model relates to a kind of iodine production equipment, especially a kind of improved iodine absorption tower.
Background technology
Iodine is a kind of scarce resource in the world, and iodine not only can be used as industrial production raw material, but also is medically being widely used, and iodine is the trace element of needed by human.Along with socioeconomic development, people are also increasing the demand of iodine, and still, the stock number of iodine is few, and extract also difficulty, and the equipment of industrial extraction iodine is complicated, and cost is high, and effect is undesirable.
Patent 200820301318.3 discloses a kind of iodine absorption tower, and packed tower top is provided with water inlet, and tower body bottom is provided with air inlet, tower body top is provided with gas outlet, tower body bottom is provided with delivery port, and the iodine wherein of the aqueous solution absorption containing reducing agent for gas containing iodine mixes in tower.
Actual use discovery, the gas containing iodine in above-mentioned iodine absorption tower moves from bottom to top, and the aqueous solution of reducing agent is from top to bottom, their move toward one another, time of contact is short, in addition, the aqueous solution of reducing agent skewness in filler, these factors cause containing iodine gas and do not obtain abundant Reducing and absorption.
As from the foregoing, above-mentioned existing iodine absorption tower, in actual use, obviously has defect and exists, and need to be improved.
Summary of the invention
For the deficiencies in the prior art part, the utility model aims to provide a kind of improved iodine absorption tower, to guarantee that the aqueous solution of reducing agent is evenly distributed, containing iodine gas, fully contacts with the aqueous solution of reducing agent, improves the absorptivity of iodine.
The technical solution adopted in the utility model: a kind of improved iodine absorption tower, comprise tower body, in tower body top, interchanger is set, in tower body bottom, one side arranges air inlet pipe, in tower body bottom, one side sets out water pipe, at tower body top, set out tracheae, the both sides of described interchanger are water tank A and water tank B, the outside coupled reaction raw material water inlet pipe A of water tank A, the outside coupled reaction raw material water inlet pipe B of water tank B, on water tank A, be provided with shower plate A, on water tank B, be provided with shower plate B, shower plate A is relative with shower plate B and separated by a distance, at shower plate A and shower plate B surface uniform, through hole is set, the through hole on shower plate A and shower plate B surface corresponding setting of mutually staggering, bottom between two water tanks arranges dividing plate.
The through-hole diameter that shower plate A and shower plate B surface arrange is 2-4 millimeters.
The upper adjacent through-holes spacing of shower plate A or shower plate B is 1-2 centimetres.
Adopt after said apparatus, water inlet pipe at two water tanks passes into respectively the reducing agent aqueous solution, two water inlet pipe domestic demands keep certain pressure, the reducing agent aqueous solution enters respectively after two water tanks like this, through hole ejection from the shower plate surface of water tank, due to the through hole on two shower plate surfaces corresponding setting of mutually staggering, reducing agent aqueous solution water column is beaten respectively on shower plate surface over there and is formed water smoke, so also relatively reduced the decrease speed of the reducing agent aqueous solution, these water smokes fully blend and mix with containing iodine gas, containing the iodine in iodine gas, fully replaced, then the reducing agent aqueous solution is discharged by outlet pipe.
This device compared with prior art, consume equal number containing iodine gas time, can effectively improve iodine uptake, and the reducing agent aqueous solution consuming reduces.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In accompanying drawing: 1 air inlet pipe 2 escape pipe 3 water tank A 4 water tank B 5 water inlet pipe A 6 water inlet pipe B 7 shower plate A 8 shower plate B 9 outlet pipe 10 dividing plates.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, tower body integral body is cylindrical, in tower body top, interchanger is set, interchanger integral body is cuboid, in tower body bottom, one side arranges air inlet pipe 1, containing iodine gas, from air inlet pipe 1, enter in iodine absorption tower, in tower body bottom, one side sets out water pipe 9, at tower body top, set out tracheae 2, containing iodine gas replaced after iodine, from escape pipe 2, discharge, the both sides of described interchanger are water tank A3 and water tank B4, the outside of water tank A3 connects water inlet pipe A5, the reducing agent aqueous solution enters water tank A3 from water inlet pipe A5, the outside of water tank B4 connects water inlet pipe B6, the reducing agent aqueous solution enters water tank B4 from water inlet pipe B6, total tune for interchanger, water tank A3 and water tank B4 are processed as same size, on water tank A3, be provided with shower plate A7, on water tank B4, be provided with shower plate B8, shower plate A7 is relative with shower plate B8 and separated by a distance, at shower plate A7 and shower plate B8 surface uniform, through hole is set, the diameter of through hole is 2 millimeters, if the diameter of through hole is excessive, the fully atomization of the reducing agent aqueous solution, if the diameter of through hole is too small, also easily produce and stop up, the through hole on shower plate A7 and shower plate B8 surface corresponding setting of mutually staggering, from the water column of shower plate A7 ejection, beat on shower plate B8 surface like this, form water smoke, from the water column of shower plate B8 ejection, beat on shower plate A7 surface equally, form water smoke, more than the hydraulic pressure of water tank A3 and water tank B4 must keep 0.2MPa, bottom between water tank A3 and water tank B4 arranges dividing plate 10, dividing plate 10 is network structure, containing iodine gas, by dividing plate 10, enter in interchanger, the reducing agent aqueous solution flows into outlet pipe 9 by dividing plate 10 and enters next process.
