Abstract
The invention relates to an electrolyte cooling device in a zinc hydrometallurgy device. The device adopts a technical proposal that a spray device of a zinc electrolyte cooling tower comprises more than ten branch pipes, spray racks arranged on the lower ends of the branch pipes, and 4 spray nozzles arranged on each spray rack, wherein the branch pipes are evenly distributed in the upper space of a tower body, are communicated with a liquid inlet main pipe, and are extended downwardly and vertically; and the spray nozzles are arranged at certain intervals and face different directions. The electrolyte cooling device is characterized in that the branch pipes and the spray racks are made of polypropylene. One of four small branch pipes is in a horizontal status; and the other three small branch pipes are arranged at 15 to 30 degrees to the horizon. Through improving the material of spray pipes, the electrolyte cooling device reaches the effect of improving the surface fineness inside the pipes, brings about high fineness inside the pipes, few host crystals, and smaller adhesion to the crystals than that of PVC, greatly reduces the adhesive rate of the crystals, reduces the adhesion speed of the crystals, and reduces the reduction speed of the effective diameter of each pipe. In addition, the crystals are easy to fall off. The crystals fall off in blocks with a sight shock from an external force and are easy to be collected.
Description
Technical field
The present invention relates to a kind of metal melting equipment, the electrolytic solution refrigerating unit in particularly a kind of zinc hydrometallurgy equipment.
Background technology
Zinc hydrometallurgy is the general technology that zinc is smelted, in its electrowinning process, the zinc electrolyte that is produced need cool off, generally be to adopt cooling air mode, high temperature waste liquid after the electrolysis through pipe-line transportation to the cooling tower cat head, by the cooling tower spray equipment waste liquid is sprayed again, form vaporific spray liquid, cool off by air by convection current.The structure of cooling tower commonly used is: constitute a rectangular parallelepiped tower body that is about 10m, wide about 5m, high about 12.5m mutually by the polylith glass epoxy, in its bottom sides a blast apparatus is installed, spray equipment is installed on the cooling tower top, liquid from top to bottom, gas carries out heat exchange by convection current from bottom to top.The composition of its spray equipment is: many be distributed in tower body internal upper part space, be responsible for feed liquor be connected, downwards drawdown arm, be installed on each arm lower end and horizontally disposed spray frame, there are four to keep at a certain distance away on each spray frame, form spray equipment towards the shower nozzle of different directions.A whole set of spray equipment is vertical with the feed liquor person in charge with flange and connects, and each parts of spray equipment also adopt flange to connect, as shown in Figure 1.Electrolytic solution is responsible for through feed liquor and is flow to each arm, enters the spray frame again, sprays from each nozzle.In the prior art, each arm, the spray frame pipe fitting generally by
The pvc pipe of 90mm is welded.As shown in Figure 1: the spray frame is welded by two straight tube T types of 1m and 0.5m, add the straight tube of 2m after, whole own wt is about about 15kg.
In suitability for industrialized production, because the electrolytic electrolytic solution of zinc is in working cycle, foreign ions such as the calcium in the electrolytic solution, magnesium can descend and constantly crystallization by Yin Wendu, its xln is attached to the inwall of shower, the inwall of shower thickens because of calcium magnesium xln adheres to constantly, and crystallization velocity is fast, cause the effective internal diameter of pipeline constantly to dwindle, flow also constantly dwindles, the deadweight of spray equipment does not increase absolutely, have a strong impact on the cooling performance of spray, after after a while, can cause the flow of cooling system not reach the production demand.Through applicant actual measurement, a cooling tower through 40 days use after pipe intercrystalline thickness can reach 15～20mm, its device overall weight can reach about 31～38kg.For this reason, manufacturer has to adopt many cooling towers to recycle, and stops using in turn, with the purge tube intercrystalline, guarantees that quantity-produced needs.Its cleaning work can not be carried out in cooling tower, can only move on to ground and clear up installation with spray equipment integral body from being unloaded by tens meters high cooling tower cat head.Its drawback is:
1, have xln to adhere to back spray equipment overall weight weightening finish in the pipe, hoisting difficulty is big, has potential safety hazard during the cleaning lifting;
2, need bigger work-yard, labor intensity of operating staff is big;
3, in the scale removal process, because PVC (polyvinyl chloride) material is crisp, the repair rate in the operation reaches 87%, and loss is serious.
The processing power of cooling system is very big to the throughput influence of zinc electrolyzer, the existence of the problems referred to above causes its rated load of processing power no show of cooling system, have a strong impact on the integral production ability of zinc electrolyzer, need the cooling tower spray equipment is improved.
Summary of the invention
The object of the present invention is to provide a kind of spraying apparatus of zinc electrolyte cooling column, it has from advantages such as heavy and light, spray is effective, crystallization velocity is slow, the loose easy to clean of the nuclei of crystallization.
Technical scheme of the present invention is: a kind of spraying apparatus of zinc electrolyte cooling column, it comprise more than ten be distributed in tower body internal upper part space, with feed liquor be responsible for be connected, downwards drawdown arm, be installed on the spray frame of each arm lower end, each spray have on frame four keep at a certain distance away, towards the shower nozzle of different directions, it is characterized in that: the material of described arm and spray frame is a polypropylene.
As to further improvement of the present invention, one is horizontality in described four smaller branch pipe, and its excess-three root and level are 15～30 degree angles.
As to further improvement of the present invention, the spout of described spray header is
25～
35, angle of rotation is 90 degree～150 degree.
Beneficial effect of the present invention is:
1, the present invention is by improving the material of shower, reach the effect that improves pipe internal surface smooth finish, make that pipe internal surface is highly polished, the nuclei of crystallization are few, little to the crystalline adsorptive power than PVC, greatly reduce the adhesive rate of xln, slow down crystallization and adhere to speed, reduce the speed of dwindling of the effective diameter of pipeline, and xln comes off easily, and external force vibrations xln will become piece to come off a little, is easy to cleaning.
2, the present invention can reach maximum running orbit by the pitch angle of smaller branch pipe being set, making the fog-like liquid that sprays out in air-cooled process, has reached the purpose of even sprinkling, also reaches best cooling-down effect with regard to the time that has increased heat exchange.
3, under the impregnable prerequisite of the atomizing effect of liquid, used bigbore polypropylene shower nozzle, increased the flow of spout, also guaranteed cool effect, solved the contradiction between flow and cooling-down effect.
4, because proportion is 0.97～1g/cm
3Polypropylene material, proportion more of the prior art are 1.45～1.65g/cm
3Polyvinyl chloride light makes the weight reduction of spray equipment, uses proof through the applicant, and this spray equipment deadweight only be 4.2kg, is 5～8mm through the xln thickness of 70 days use postadhesion, the minimum 18.8mm that increases of single arm sectional area
2, weight is about 11.4kg.
5, the polypropylene material has certain toughness, and shower is not fragile, the recovery utilization rate height.Use product of the present invention can prolong cleaning cycle, the cleaning cycle of cooling tower was extended to about 90 days, reduce worker's labour intensity, increase work efficiency, improved the production processing power of cooling system.
