A device for recycling waste heat of tube furnace tail gas

Abstract

The invention discloses a recovery and utilization device for the waste heat of a tubular furnace exhaust gas. The recovery and utilization device comprises a shell, wherein a heat exchange component, a purification component and a mixing component are arranged in the shell, and the heat exchange component is connected with the purification component by a pipeline, The purification component is connected with the mixing component pipeline, the heat exchange component is connected with the tube furnace pipeline, and the heat exchange component exchanges heat with air through pressurization. The particles are removed from the exhaust gas and the air is mixed by the mixing assembly by Bernoulli principle. The heat exchange component increases the temperature through pressurization and heats the air inside the shell, so that the waste heat of the exhaust gas can be fully utilized. At the same time, when the heat exchange component releases the pressure, the exhaust gas with particles collides with each other in the purification component and passes through the van der Waals force. Attracting each other together, reducing the existence of particles and improving the purification effect of particles.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery and utilization, in particular to a recovery and utilization device for the waste heat of a tubular furnace tail gas. Background technique [0002] Tube furnaces are mainly used in metallurgy, glass, heat treatment and lithium battery positive and negative materials industries. Tube furnaces are divided into various furnace types, including single-tube, double-tube, horizontal, vertical, single-temperature zone, dual-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, large temperature range, high furnace temperature uniformity, and many temperature zones. [0003] The tail gas of the tube furnace contains a lot of heat energy, but the treatment method of the tail gas of the tube furnace is generally a direct discharge method, which not onl...

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
