Processing equipment for low heat value wastes and processing method

Abstract

The invention relates to processing equipment for the low calorific value waste and a processing method thereof. When the waste is incinerated in an incinerator, part of generated high-temperature gas is transmitted into a rotary kiln for conducting heating, drying and incinerating treatment to the low calorific value waste; the volume of the high-temperature gas entering the rotary kiln is controlled by controlling the air supply volume of a high-temperature fan, so the temperature requirement of the rotary kiln is achieved; by temperature control, various components of the low calorific value waste are respectively treated such as drying, recycling, incineration, etc. As a pipeline and a high-temperature fan are arranged, the invention can transmit the heat in the incinerator to the rotary kiln, the fuel in the rotary kiln is not needed to be heated, and the energy is saved, thereby being quite environmental-protection to the recycle and use of a plurality of materials.

Description

technical field [0001] The invention relates to the technical field of recycling and harmless treatment of waste, in particular to a device and method for treating waste with low calorific value. Background technique [0002] The most widely used method of waste treatment in the world is incineration treatment, including direct incineration method and comprehensive incineration treatment method. The incineration treatment method is due to its small footprint, thorough treatment, obvious reduction, and easy waste heat synthesis. Utilization, no pollution and other characteristics, its advantages are very prominent. There are various forms of waste, which can be generally divided into those that can be directly incinerated and those that cannot be directly incinerated. Generally, among those that cannot be directly incinerated, some have high water content, and some are non-incinerable inorganic minerals with a small amount of incinerable parts. It is generally called low cal...

Problems solved by technology

There are various forms of waste, which can be generally divided into those that can be directly incinerated and those that cannot be directly incinerated. Generally, among those that cannot be directly incinerated, some have high water content, and some are non-incinerable inorganic minerals with a small amount of incinerable parts. It is generally called low calorific value waste. However, due to the complex composition and low calorific value of low calorific value waste, it is difficult for ordinary small incinerators to incinerate directly, and there are some useful wastes in low calorific value waste. If it is incinerated together with other wastes, it will cause a waste of resources
