Three-phase multi-functional mixed combustion furnace

Abstract

The invention provides a three-phase all-functional multifuel burner, which comprises a main burning furnace for burning coal and waste gas. The bottom of the main burning furnace is provided with a wind chamber; the upper end face of the wind chamber is provided with an air distributing plate; air caps are uniformly distributed on the air distributing plate; a coal burning area on the middle lower part of a hearth of the main combustion furnace is slantwise or vertically provided with a plurality of water pipes which form the water circulation with the outside; the middle part of the hearth is provided with a burning nozzle; and a waste gas inlet on the middle side wall of the main burning furnace is provided with a mixed burner. The burner is characterized in that: an auxiliary burning furnace is arranged; the upper part of the auxiliary burning furnace is tangentially communicated with the main burning furnace through a flue; and the top part of the auxiliary burning furnace is provided with a waste liquid burner, the bottom is an ash outlet, and the side wall on the middle lower part is provided with a heat outlet. The multifuel burner not only can burn coal cinder and the waste gas, but also can use the high temperature generated by the burning to incinerate the waste liquid, and achieve the favorable situation that a gas phase, a liquid phase and a solid phase are burned together. The burner also can be used for dual combination burning of gas-liquid, gas-solid or liquid-solid or can singly burn one fuel, and has good working performance.

Description

technical field [0001] The invention provides a three-phase all-purpose mixed combustion furnace, which belongs to the technical field of industrial combustion furnaces. Background technique [0002] Most of the combustion furnaces in the chemical field such as fixed bed semi-water gas are waste gas combustion furnaces. In recent years, gas and solid co-combustion furnaces have appeared, that is, the lower part of the combustion furnace burns solids such as coal or cinder, and the upper part of the combustion furnace burns gas. Although this combustion technology is immature, it still solves the problem of incomplete combustion of gas in the combustion furnace due to insufficient heat source in the pure gas combustion furnace. However, most modern enterprises are comprehensive enterprises. In addition to waste gas and waste residue, there is also a lot of waste liquid, especially a large part of high calorific value or high pollution waste liquid, which brings huge economic ...

Problems solved by technology

Although this combustion technology is immature, it still solves the problem of incomplete combustion of gas in the combustion furnace due to insufficient heat source in the pure gas combustion furnace.

However, most modern enterprises are comprehensive enterprises. In addition to waste gas and waste residue, there are also a lot of waste liquids, especially a large part of high calorific value or high pollution waste liquids, which bring huge economic losses and environmental pollution to enterprises and society.
