High-efficiency rotary type heat exchanger

Abstract

The invention relates to the technical field of heat exchangers, in particular to a high-efficiency rotary type heat exchanger which comprises a processing pipe, a base, a shell, a heat exchange deflection mesh plate and a fan-shaped seal plate. The shell is arranged on the base; a hot waste gas pipe is welded to the rear position of the left end of the shell; the processing pipe is arranged at the left end of the hot waste gas pipe; a gas guiding hole of the processing pipe communicates with a gas guiding hole of the hot waste gas pipe; a cylindrical filter mesh is arranged in the middle of the inner part of the processing pipe and is rotatably connected with the processing pipe through a rotary shaft; a waste box is arranged right under the cylindrical filter mesh; and the heat exchangedeflection mesh plate is arranged in the middle of the inner part of the shell and is rotatably connected with the shell through a transmission shaft. According to the high-efficiency rotary type heatexchanger provided by the invention, through arranging the processing pipe and the heat exchange deflection mesh plate, the heat exchange efficiency of the device is improved, and the processing quality and the service life of the device are improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a high-efficiency rotary heat exchanger. Background technique [0002] The main function of the rotary heat exchanger is to absorb the waste heat discharged from the front section of the boiler to heat the boiler combustion and pulverized coal delivery air, or to reheat the flue gas cooled by the desulfurization system. The large rotary heat exchanger includes an air preheater and flue gas The heat exchanger, whose rotor filled with heat exchange surfaces can weigh hundreds of tons, uses a specially designed transmission system to ensure its continuous rotation. Therefore, the demand for a high-efficiency rotary heat exchanger is increasing. [0003] When the existing device is in use, the dust in the exhaust gas is too large to block the heat exchange baffle grid plate, thereby affecting its heat exchange efficiency, reducing the heat exchange quality of the device, redu...

Problems solved by technology

[0003] When the existing device is in use, the dust in the exhaust gas is too large to block the heat exchange baffle grid plate, thereby affecting its heat exchange efficiency, reducing the heat exchange quality of the device, reducing the service life and safety of the device, and at the same time, When the prior art is used, due to the small contact area and short contact time, the heat exchange is not complete and the heat energy is wasted. Therefore, a high-efficiency rotary heat exchanger is proposed to solve the above problems
