Potate -free treatment device

In the production of electric heating yellow phosphorus, according to statistics, every 10,000 tons of yellow phosphorus produced will produce 1500-3,000 tons of mud phosphorus (50%wetlifiers). 8%-13%of phosphorus in phosphorus is called poverty-stricken phosphorus. The phosphorus content of mud phosphorus is generally about 5%-40%, and the average of about 20%. The recycling and utilization of mud phosphorus not only eliminates the pollution of mud phosphorus to the environment, but also becomes waste into treasure to create wealth for enterprises. At present, the method of mud phosphor can be divided into two types in general. The first is combustion -making phosphoric acid, and the second is to evaporate phosphorus. These two methods are not only unable to operate continuously, but also greater environmental pollution.

The harmless treatment of mud and phosphorus is the current requirements for environmental protection and the needs of the enterprise. In order to overcome the existing technical defects, our company invented the patented product mud -phosphorus high -temperature heating evaporator device (patent number: ZL202321605525.9). After drying, the mud phosphorus is transported to the high temperature heating evaporator heating. The mud phosphorus continues to heat up at high temperature heating and evaporator to above 500 ° C, and the content of the single phosphorus of the ash to be less than 0.1%.

The design and conveying volume of the mud -phosphor and high temperature heating evaporator is designed as a double -axis W -type conveying method; the spiral shell is made of boiler steel plate, and the shaft is seamless steel pipe; the spiral blades are made of steel plate, a shaft head 45#steel; , Two -ends are used with graphite tetrafluoro aravarous high -temperature fillers. The bearings use external thrust bearing to add high temperature lubricating oil; the spiral heating section is strengthened to prevent the steel heat increase and deformed deformation. Water -cooled clamps to prevent high temperature from affecting the bearings.

The work temperature of this equipment can be set up by gradients through a controllable heating module, which can be increased by gradient, up to 1000 ° C, to meet the process requirements of evaporating phosphorus; the overall structure is reasonable, which makes the thermal machine operates smoothly and controllable. The maintenance cost of long -term use; and using conduction heating, all heating surfaces are covered by material, the heat loss is small, the internal space and heat exchange surface layout is reasonable, and the equipment occupies a small area. There is no calorie loss and safe operation; the entire confidential sealing performance is excellent, it will not pollute the environment or there is professional hazards to the operator.
