Combustion furnace and its exhaust gas treatment process

Abstract

The invention discloses a combustion furnace and a waste gas treatment technology of the combustion furnace. The combustion furnace is simple in structure and high in heat energy utilization rate, waste gas generated by the furnace can be treated, and meanwhile the waste gas treatment technology of the combustion furnace is further provided. The combustion furnace comprises a base and a furnace body arranged on the base. A sealed combustion chamber is arranged in the furnace body, and an air inlet and a fuel pipe which are communicated with the combustion chamber are arranged on the furnace body; and combustors connected with the fuel pipe are arranged in the combustion chamber. The combustion furnace is characterized in that a plurality of heat transport pipes communicated with the combustion chamber are further arranged on the furnace body, a plurality of metal plates are further arranged in the combustion chambers, and in the using process, the combustors spray gas to the metal plates for combustion. The waste gas treatment technology comprises the following steps of a, preheating; b, air source switching; and c, high-temperature pyrolyzing. The combustion furnace is applied to the technical fields of combustion furnaces and waste gas treatment.

Description

technical field [0001] The invention relates to a combustion furnace and a waste gas treatment process thereof. Background technique [0002] A large amount of heat is often required in the process of processing waste tires, which is generally provided by the combustion furnace through the combustion furnace. Most of the current combustion furnaces are not efficient, and will produce a large amount of polluting gas after combustion, resulting in high costs for enterprises to process waste tires, and also pollute the air. For example, the Chinese patent whose publication number is 204062998U discloses a combustion furnace. The funnel shape, the feed hopper is arranged in the box and above the feeding mechanism; the combustion chamber is arranged on one side of the box; the feeding mechanism includes a feeding motor, a feeding pipe and screw, the screw is horizontally arranged in the feeding pipe, the screw has a rotating shaft and a helical blade connected as one, the feedi...

AI Technical Summary

Problems solved by technology

It can be seen that the structure of the above-mentioned disclosed combustion furnace is complicated, and a large amount of polluting gas will be produced after combustion, and the waste gas produced by itself cannot be effectively treated. In the aspect of waste gas treatment, the enterprise needs to invest a large amount of money, which is not conducive to the development of the enterprise.
