Abstract
The utility model provides an insulating and heating system for producing high-purity zinc powder by using hot galvanizing slag. The insulating and heating system comprises a melting chamber, an evaporating chamber, and a distillation chamber, wherein the melting chamber, the evaporating chamber and the distillation chamber are sequentially connected; the melting chamber and the evaporating chamber are in a horizontal direction; and the distillation chamber is in a vertical direction. The insulating and heating system is characterized in that a heat-conducting oil interlayer is arranged at the outer side of each of the three chambers; heat-conducting oil is injected into each heat-conducting oil interlayer; and an insulating layer is arranged at the outer side of each heat-conducting oil interlayer far away from the corresponding one of the three chambers. The system also comprises a gas heating furnace and a circulating pump arranged at the outlet of the heat-conducting oil; the gas heating furnace is respectively connected with the heat-conducting oil interlayers of the three chambers; and the heat-conducting oil interlayers of the three chambers are connected with the gas heating furnace through a common loop. The insulating and heating system has the advantages and beneficial effects that the heat-conducting oil is utilized for heating in a circular manner; the resource can be saved; the insulating and heating system is more environment-friendly; the reaction condition can be accurately controlled by use of a temperature sensor and a digital display instrument; the insulating layer effectively prevents heat loss; the utilization efficiency of the heat is improved; and the cost is reduced to a certain extent.
Description
Technical field
The utility model relates to a kind of Heat preservation system that produces the high purity zinc powder.
Background technology
At the zinc powder production industry, prepare highly purified zinc powder, adopt distilled condensation methods more now, and common device has horizontal and tower two kinds, and is horizontal more commonly used, generally for some medium-sized and small enterprises, invest less can the realization, but effect is general, the impurity in zinc liquid is residual more, especially the applicant uses hot galvanizing residue to produce as raw material, can cause a large amount of lead residual; Tower investment is too large, and production cost is too high.
Above-mentioned two kinds of equipment all need to heat, make cadmia melt, and separate according to the difference of boiling point, existing heating is mainly to adopt gas heating, wastes on the one hand resource, and heats is not good on the one hand, can't reach required temperature, and the integral heat insulation weak effect causes the part heat loss, has reduced production efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of Heat preservation system that utilizes hot galvanizing residue production high purity zinc powder, has environmental protection, capable of circulation, controllable characteristics.
The technical solution of the utility model is: a kind of Heat preservation system that utilizes hot galvanizing residue production high purity zinc powder, comprise melting chamber, evaporator room, rectifying chamber, the three is connected successively, melting chamber and evaporator room are horizontal direction, the rectifying chamber is vertical direction, it is characterized in that: the outside in above-mentioned three Room is respectively arranged with conduction oil interlayer, interior notes thermal oil, conduction oil interlayer has thermal insulation layer away from the arranged outside of three Room.
System also comprises gas-fired heater and is arranged on the recycle pump in thermal oil exit.Described gas-fired heater is connected with the conduction oil interlayer of three Room respectively, and the conduction oil interlayer of three Room is connected with gas-fired heater by common loop.
The conduction oil interlayer of melting chamber, evaporator room, rectifying chamber is independent mutually, and is respectively equipped with temperature sensor and digital display instrument, temperature accurately can be controlled within limits, help to improve rectification effect.
Described temperature sensor one end inserts in thermal oil, and an end is connected with digital display instrument.
Described thermal insulation layer is the rock wool heat-preservation material.
Advantage and the positively effect that the utlity model has are: use the thermal oil circulating-heating, can economize on resources, also environmental protection more; Reaction conditions can be accurately controlled in the use of temperature sensor and digital display instrument; Thermal insulation layer effectively prevents heat loss, has improved the utilising efficiency of heat, has reduced to a certain extent cost.
