Problems solved by technology
A large amount of low calorific value organic waste liquid is often produced in industrial production. For example, 1 ton of alcohol will produce 15 tons of alcohol waste liquid. If these waste liquids are discharged directly, they will seriously pollute the environment and destroy the ecological balance.
The method of treating organic waste liquid by combustion method is a common and reasonable method at present. Some enterprises mix the waste liquid with bagasse or coal and burn it. The disadvantage of this method is that it consumes a lot of energy and the amount of waste liquid treatment is limited. It is easy to accumulate ash, which affects the long-term safe operation of the boiler and reduces the efficiency of the boiler

The invention provides a low heat value organic waste liquid burner. The structure character is: the bottom is boiling bed, the top is waste liquid concentrator; the top and wall of waste liquid concentrator between in and out wall have concentrating grooves, the bottom of wall grooves has material outlet which connects with concentrating liquid inlet at the boiling segment of boiling bed through exporting pipe, there are waste liquid pre-warmer and air pre-warmer at the smoke outlet in burner cavity.
Description
1. Technical field [0001] The invention relates to a combustion device for the purpose of treating low calorific value organic waste liquid. 2. Background technology [0002] Due to its high moisture and low calorific value, organic waste liquid is difficult to burn directly and maintain combustion. The so-called low calorific value means that the low calorific value is less than 1000kcal / kg, and generally refers to the calorific value with a calorific value of 500-600kcal / kg. A large amount of low calorific value organic waste liquid is often produced in industrial production. For example, 1 ton of alcohol will produce 15 tons of alcohol waste liquid. If these waste liquids are discharged directly, they will seriously pollute the environment and destroy the ecological balance. The method of treating organic waste liquid by combustion method is a common and reasonable method at present. Some enterprises mix the waste liquid with bagasse or coal and burn it. The disadvantage...
