Tubular furnace tail gas waste heat recycling device

Abstract

The invention discloses a tubular furnace tail gas waste heat recycling device. The tubular furnace tail gas waste heat recycling device comprises a shell; a heat exchange assembly, a purification assembly and a mixing assembly are arranged in the shell; the heat exchange assembly is in pipeline connection with the purification assembly; the purification assembly is in pipeline connection with themixing assembly; the heat exchange assembly is in pipeline connection with a tubular furnace; the heat exchange assembly exchanges heat with air through pressurization; the purification assembly increases the weight of particles through Van der Waals' force; the purification assembly removes the particles in tail gas; the mixing assembly mixes the tail gas and the air through the Bernoulli principle; the heat exchange assembly increases the temperature through pressurization and heats air in the shell; tail gas waste heat can be fully utilized; meanwhile, when the heat exchange assembly releases pressure, tail gas with particles collides with one another in the purification assembly and is attracted together through Van der Waals' force; particles are reduced; and the particle purification effect is improved.

Description

technical field [0001] The invention relates to the technical field of recovery and utilization of waste heat, in particular to a recovery and utilization device for waste heat of tail gas of a tubular furnace. Background technique [0002] Tube furnaces are mainly used in metallurgy, glass, heat treatment and lithium battery positive and negative materials and other industries. Tube furnaces are divided into various furnace types, including single tube, double tube, horizontal, vertical, single temperature zone, double temperature zone, three-temperature zone, etc. The tube furnace has the characteristics of safety and reliability, simple operation, high temperature control accuracy, good heat preservation effect, wide temperature range, high furnace temperature uniformity, and multiple temperature zones. [0003] The tail gas of the tube furnace contains a lot of heat energy, but the treatment method for the tail gas of the tube furnace is generally to adopt the method of...

Problems solved by technology

[0003] The tail gas of the tube furnace contains a lot of heat energy, but the treatment method for the tail gas of the tube furnace is generally to adopt the method of direct discharge, which not only wastes the heat energy contained in the tail gas, but also greatly reduces the utilization rate of energy. Exhaust gas contains a lot of dust, if the exhaust gas is directly discharged into the air, it will cause serious air pollution
