Guiyang Phosphorus Kaiyang to build coal-chemical industry – Air Treatment Combi
In the past, Guiyang City Kaiyang of phosphorus chemical factory chimneys, without exception, black smoke, but now, you will find these chimney smoke is not smoke, but the fire slightly, all thanks to the phosphorus chemical industry enterprise based on the concept of circular economy, implement clean production, improve resource utilization and by-products and waste comprehensive utilization.
November 1, 2004, China’s first recycling economic regulation – “the building of circular economy Guiyang Ecological City Ordinance,” formal implementation. Since the Ordinance came into operation, Guiyang City, adhere to the project as the core, works as a carrier, focused stages, sub-regional, sub-levels progress, the building of eco-city recycling economy. Through careful organization and implementation, demonstration projects, successful, has played a powerful demonstration effect. Phosphorus chemical plant will benefit from cleaner production implementation of the Ordinance.
According to reports, these companies in the production process, will produce more than 90% of the carbon monoxide exhaust, such as emptying all the combustion is not only a waste, and air pollution. However, the entire process of production to take the relevant measures of circular economy, carbon monoxide, both as a supplementary energy to produce defluorinating tricalcium phosphate, both solved the production problem of inadequate energy supply on the same time eliminating the tail gas pollution of the atmosphere of yellow phosphorus . Left after production of solid waste, can be sold to cement plants as raw material, but also can be made into glass-ceramic materials not only reduce the cost of disposal of waste and can profit from it.
The open-yang as the country’s three major phosphate rock phosphate rock, one of the world’s phosphorus chemical products in more than 2,000 and open phosphorus group produced only 10 kinds of low output and small size. On the other hand, mining the discharge of industrial waste water each year nearly one million tons, phosphorus slag, fly ash and other solid waste more than 100 million tons, 3 million cubic meters of yellow phosphorus combustion exhaust venting. Mine recovery rate is low, an average of only 60%. A backward mining methods result in serious damage to the environment and resources, frequent geological disasters. Recycling economy project through source control of phosphorus resources and energy consumption reduction, waste of resources utilization and eco-industrial chain network construction, the production process to reduce raw material consumption and waste emissions and take full advantage of each other by-products and waste generated by very land to reduce pollution and impact on the natural environment.
Concept of circular economy for the development of phosphorus chemical Kaiyang injected a dose of tonic. Kaiyang efforts to build coal chemical phosphorus (State) eco-industrial demonstration bases, the base is completed, to reduce annual emissions of phosphorous slag 1 million tons, 3 million tons of phosphogypsum, fly ash 30.5 million tons. And a series of new technology, lengthening the industrial chain, to 2008, phosphorus chemical products will be increased to 60, the product total of 300 million tons, total industrial output value reached 80 billion yuan, increasing employment 15000 persons.
