Efficient sludge incinerator

Abstract

The invention relates to incineration equipment, in particular to an efficient sludge incinerator capable of allowing sludge to be incinerated fully. The efficient sludge incinerator comprises an incinerator body which is cylindrical and is arranged vertically, wherein the bottom of the incinerator body is sealed; an exhaust gas outlet is formed in the top of the incinerator body; a mixing device is arranged at the bottom of an inner cavity of the incinerator body; a feed port and a burner are formed and arranged in the side wall of the incinerator body above the mixing device; and an ash outlet is formed in the bottom of the incinerator body. The efficient sludge incinerator is characterized in that the mixing device is in a hollow steel pipe structure; an air inlet is formed in one end, stretching out of the bottom of the incinerator body, of the efficient sludge incinerator; and an air outlet is formed in the mixing device positioned in the incinerator body. According to the efficient sludge incinerator, combustion-supporting air entering the incinerator body can be sufficient, and can be uniformly mixed with to-be-incinerated sludge particles, so that the sludge particles in the incinerator body can be incinerated completely, and the sludge incineration efficiency can be improved greatly.

Description

technical field [0001] The invention relates to an incineration equipment, in particular to a high-efficiency sludge incinerator capable of fully incinerating sludge. Background technique [0002] It is known in the incineration industry that the sludge incinerator is a device that can heat and dry the dewatered sludge, and oxidize the organic matter in the sludge with high temperature, so that the sludge becomes a small amount of ash. [0003] A traditional sludge incinerator includes a furnace body, which is cylindrical and vertically arranged, with a closed bottom and a waste gas outlet at the top; a stirring device is provided at the bottom of the inner cavity of the furnace body, and one side of the stirring device There is a combustion-supporting air inlet on the side wall of the furnace body, a feed inlet and a burner on the side wall of the furnace body above the stirring device, and an ash outlet at the bottom of the furnace body. When this sludge incinerator is in...

AI Technical Summary

Problems solved by technology

Although the combustion-supporting air can be mixed with the sludge particles to be incinerated under the agitation of the stirring device, the combustion-supporting air entering the furnace body is often not sufficient due to the limitation of the inlet position of the combustion-supporting air, and it is impossible to realize the mixing with the sludge particles to be incinerated. Uniform mixing, so that the sludge particles in the furnace cannot be completely incinerated, so that the efficiency of sludge incineration is greatly limited
