Method for producing cement by using garbage

Abstract

The invention relates to a method for producing cement by using garbage. The method is mainly and mainly characterized in that the garbage is screened and classified; and after the usable part of the garbage is crushed and the contents of calcium element, silicon element, ferrum element, aluminum element, sulfur element, magnesium element, potassium element and sodium element of the garbage are analyzed, a small amount of materials are supplemented for producing the cement. The invention has the benefits that the calcium element, silicon element, ferrum element, aluminum element, sulfur element, magnesium element, potassium element and sodium element of the garbage and effective components with thermal value are used to produce the cement instead of clay (or shale), calcium carbonate and coal in a traditional cement raw material, so that precious natural resources are saved; and more importantly, the garbage is changed into valuables, a large amount of garbage is consumed, the environment is protected and the industrial policy of national energy saving and emission reduction is met. In addition, raw materials are easily obtained, so that the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a cement production method. Background technique [0002] At present, cement production is carried out by using raw materials such as limestone, clay (shale), coal, etc. Such a production method consumes a lot of natural resources and has high production costs. [0003] At the same time, my country currently produces an average of 1.28 kilograms of garbage per person per day, and more than 178 million tons of garbage is produced every day in the country, and it will increase at a rate of 10%. my country's cities and towns have been surrounded by more than 6 billion tons of garbage, and the annual increase is about 500 million tons. Environmental protection experts pointed out that using hundreds of acres of land to build a landfill with a daily capacity of 100 tons of domestic waste is essentially garbage moving, centralized stacking, three-dimensional pollution, landfill leachate and odor pollution, and the emitted methane ca...

Problems solved by technology

The common problems are that they occupy a large amount of land, invest a lot of money, have a long treatment process, and produce secondary pollution to varying degrees.

Dioxin will be produced during garbage incineration, leachate, methane and stench will be produced during garbage pretreatment, and the treatment process will be long, etc.
