Description

A kind of Phosphorus Slag solution generates the method for lagging material

Technical field

The present invention relates to the regeneration method of Phosphorus Slag, particularly relate to a kind of method that Phosphorus Slag solution generates lagging material.

Background technology

In the process of producing yellow phosphorus, a large amount of Phosphorus Slags and carbon monoxide can be discharged, difficult treatment, contaminate environment.Application number be 88105942.0 application for a patent for invention disclose a kind of generation method utilizing the direct fibroblast of Phosphorus Slag, utilize the high-temperature slag meeting fibre-forming condition smelted yellow phosphorus electric furnace and discharge, adopt pneumatics to blow cotton technique and be directly blow molded into ca silicate fibre cotton, air compressor machine blows cotton operating pressure 0.4 ~ 0.6MPa, adopt double V-shaped nozzle, be less than 1400 DEG C in material temperature and become cotton.But the unexposed concrete operation step of this application, lacks operability.The patent No. be 200710054726.3 patent of invention disclose a kind of Phosphorus Slag solution and produce the method for lagging material, at the slag notch of yellow phosphorus ore deposit smelting furnace, diversion trench is set, the Phosphorus Slag solution of discharge is caused above the thumb wheel of high-speed rotation, thumb wheel sense of rotation arranges recovery approach, arrange blower back to thumb wheel, Phosphorus Slag solution has got rid of and has drawn wire under the effect of blower by thumb wheel.This method give concrete operation step, workable, but though described diversion trench is made by lagging material, can be bad for high temperature Phosphorus Slag heat insulation effect in production practice, the yellow phosphorus mineralising stove production cycle is about 4 hours, the discharge yellow phosphorus quantity of slag is about ten tons, drain time is half an hour, if the Phosphorus Slag full scale production of about ten tons is not digested within the halfhour time, temperature then can be caused to decline and be difficult to continue to produce, if complete production within half an hour, then equipment investment is excessive, but also will have the damp production waiting for Phosphorus Slag for four hours; In addition, the lagging material that the method is produced does not add other raw materials owing to only utilizing Phosphorus Slag itself, makes the lagging material produced generally can only be used for the hot vessel insulation of less than 400 DEG C.The problem of all unresolved carbon monoxide off gas treatment of aforementioned two patent documentations.

Glass melter, refers to the Thermal Equipment for fusion cast glass admixtion in glass manufacture, by the grog (glass cullet) of the powder prepared by glass ingredient and admixture high temperature melting, clarification form the glass metal meeting forming requirements in kiln.(Baidupedia, glass melter, http: ∥ baike.baidu.com/view/1865782.html) therefore, glass melter is a kind of well Heat preservation equipment, but there is the problem of the structure utilizing glass melter and principle solution Phosphorus Slag solution production lagging material in prior art, in practice, do not find that Phosphorus Slag solution produces the example of lagging material.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of method that Phosphorus Slag solution generates lagging material, the method can realize continuous free of discontinuities and produce, the lagging material of high temperature resistant (less than 1200 DEG C) can be produced, and effective processing and utilizing carbon monoxide waste gas, there is economy and environment double benefit.

In order to solve the problems of the technologies described above, the present invention takes following technical scheme:

A kind of Phosphorus Slag solution generates the method for lagging material, it is characterized in that: the Phosphorus Slag solution that Phosphorus Slag mineralising fire grate is put is imported multi-functional accumulation of heat zirconium stove, after multi-functional accumulation of heat zirconium stove insulation or heating, enter Water Cooled Centrifugal Machine, be rotated into cotton by Water Cooled Centrifugal Machine and blown out by blower fan.

Or, in multi-functional accumulation of heat zirconium stove, adding the high-al clay that weight is Phosphorus Slag solution 30 ~ 60% or adding weight is Phosphorus Slag solution 40 ~ 60% sintered coal gangue, be heated to 1600 ~ 2000 DEG C of fusion and decomposition, import Phosphorus Slag solution again and discharge, be rotated into cotton by Water Cooled Centrifugal Machine and blown out by blower fan.

The fuel used carbon monoxide put for Phosphorus Slag mineralising fire grate of multi-functional accumulation of heat zirconium stove, is provided with infrared thermometer above multi-functional accumulation of heat zirconium stove.

Multi-functional accumulation of heat zirconium stove, adopts the basic structure of cell furnace and principle to make, adopts the zirconia block of high-temperature heat-resistance, can be heated to 1600 ~ 2000 DEG C with Phosphorus Slag solution contact position.

The invention has the beneficial effects as follows, owing to have employed multi-functional accumulation of heat zirconium stove, both the Phosphorus Slag solution in stove can be kept original temperature thus carried out free of discontinuities production, can add again containing aluminium ore material, heating makes it decompose, thus produce high-temperature-resistant thermal-insulation material, can for less than 1200 DEG C hot vessel; Carbon monoxide is used for fuel, there is economy and environment double benefit.
