Kiln tail gas recovery application device and method

Abstract

The invention discloses a kiln tail gas recovery application device comprising a kiln, a gas system used for storing gas, a first ventilator, a heat exchanger and a chimney. The kiln is provided witha gas inlet and a tail gas outlet; the tail gas outlet communicates with a first inlet of the heat exchanger through a first tail gas pipeline; a first outlet of the heat exchanger communicates with the chimney through a second tail gas pipeline; the first ventilator communicates with a second inlet of the heat exchanger through a first air pipeline; a second outlet of the heat exchanger communicates with the gas inlet through a second air pipeline; and the gas system communicates with the gas inlet through a gas pipeline. According to the kiln tail gas recovery application device, the combustion heat effect in the kiln can be improved, the temperature in the kiln can be increased, the gas consumption can be reduced, meanwhile, external heat pollution is reduced, and the purposes of savingmore energy and being more environmentally friendly are achieved. The invention further discloses a kiln tail gas recovery application method.

Description

technical field [0001] The invention relates to the technical field of tail gas application, in particular to a kiln tail gas recovery application device and method. Background technique [0002] Kilns are equipment made of refractory materials for firing products or ferromagnetic materials. They are mainly divided into coal-fired kilns, electric kilns and gas kilns. [0003] Most of the traditional industrial kilns use coal as fuel, but due to high energy consumption and high pollution, they are abandoned or improved to use gas, heavy oil, and light diesel as fuel. Electric kiln: Electricity is used as the energy source, and most of them use electric furnace wire, silicon carbide gang or molybdenum disilicide as the heating element, relying on the principle of electric energy radiation and heat conduction for firing in an oxidizing atmosphere, electronic program control, simple operation, good safety performance, suitable for All kinds of workplaces, but for high-volume ce...

AI Technical Summary

Problems solved by technology

[0004] However, the combustion process of the kiln produces a large amount of tail gas, exhaust gas discharge and a large amount of heat energy, which causes thermal pollution to the environment. In order to reduce the thermal pollution to the environment, it is necessary to improve the existing technology
