Normal-pressure smoke-free environment-friendly combustion furnace

Abstract

The invention discloses a normal-pressure smoke-free environment-friendly combustion furnace and relates to the technical field of combustion furnaces. The combustion furnace comprises a furnace body and a water jacket, wherein the water jacket is arranged inside the furnace body and is communicated with a water tank; a rotary smoke flue connected with a chimney is arranged at the upper part of the back of the furnace body; a feeding opening communicated with a dry distillation chamber is formed in the upper part of the side wall of the furnace body; a water discharging opening and a water returning opening are formed in the back of the furnace body; a combustion kiln is arranged at the lower part of the dry distillation chamber; the combustion kiln is horizontal; the longitudinal section of the combustion kiln is arched; one end of the combustion kiln is fixed at the front of the furnace body; a kiln door is formed in an open end; the other end of the combustion kiln is fixed in the middle of the furnace body; gaps are formed between two sides of the combustion kiln and the inner wall of the dry distillation chamber; the back of the combustion kiln is communicated with a secondary combustion chamber; a furnace grate is arranged under the combustion kiln; a furnace dust cleaning mechanism connected with the furnace grate is arranged on the outer side of the furnace body; a main dust cleaning door with an air inlet is arranged under the furnace grate. According to the normal-pressure smoke-free environment-friendly combustion furnace, the fuel can be dispersed in the dry distillation chamber and the furnace grate by virtue of the combustion kiln; through the adoption of the combustion kiln and the secondary combustion chamber, the fuel can be fully combusted; through the adoption of the S-shaped rotary smoke flue, the dust emission is reduced; the purposes of saving energy, avoiding smoke and protecting environment can be achieved.

Description

technical field [0001] The invention relates to the technical field of combustion furnaces, in particular to an atmospheric pressure smokeless environment-friendly combustion furnace. Background technique [0002] The main heating equipment used for heating in winter in rural areas without central heating in northern my country is civil water heating stoves (commonly known as soil heating stoves). The customs formed over the years and the habits of farmers who are thrifty and housekeeping determine that the fuels used by farmers for heating are relatively complicated and mostly inferior. , Preferable bituminous coal, tree branches, waste combustible materials, etc. Most of the old-style stoves are vertical furnaces, and the fire outlet on the upper part of the furnace is directly connected to the outside, which can easily cause insufficient fuel combustion, and combustible smoke and a large amount of pollutants are directly emptied, causing serious air pollution. In order to...
