Roaster waste heat collector

Abstract

The invention belongs to the technical field of roasting waste heat recovery and particularly relates to a waste heat collector for a roasting furnace. The waste heat collector comprises a cylinder; two sides of the cylinder are fixed through supports. The waste heat collector is characterized in that one side of the cylinder is provided with a heat outlet, the wall of the heat outlet is provided with a butt joint groove, a plurality of insulating metal hoses are evenly disposed at the lower end of the cylinder, and a flame path sealing head is disposed at the lower end of each insulating metal hose. The waste heat collector is simple in structure and convenient to use; interior heat of the roasting furnace is brought away by negative pressure, a blowing rack is omitted, and electric energy for the blowing rack is saved; the fact that an anode is oxidized due to high-pressure air entering a raw material box is avoided, product quality is ensured, and production cost is effectively saved; the waste heat collector is convenient to popularize and apply.

Description

(1) Technical field [0001] The invention relates to a roasting furnace waste heat collector, which belongs to the technical field of roasting waste heat recovery. (2) Background technology [0002] Contemporary society has higher and higher requirements for energy saving and emission reduction. Most of the heat generated by roasting is lost to the air, resulting in a large amount of heat loss. At present, the heat of carbon roasting generally adopts the blast frame to blow the heat in the roasting furnace into the air, so as to achieve the purpose of cooling the furnace body. Although part of the heat in the firing chamber of the roasting furnace has been utilized, the temperature of the furnace is high, and the heat contained is relatively high. A large amount of heat is lost to the air, which not only increases the temperature of the working environment but also wastes resources. For most carbon production enterprises, there are almost no roasters with waste heat recovery...

AI Technical Summary

Problems solved by technology

Although part of the heat in the furnace chamber of the roasting furnace has been utilized, the temperature of the furnace is high, and the heat contained is relatively high. A large amount of heat is lost to the air, which not only increases the temperature of the working environment but also wastes resources. For most carbon production enterprises, there are almost no roasters with waste heat recovery equipment. They just follow the consistent roasting route, which can neither respond to the call for energy saving and emission reduction nor make use of existing resources, wasting manpower, material and financial resources.
