Air preheater for high-temperature waste gas waste incineration

Abstract

The invention discloses an air preheater for high-temperature waste gas waste incineration. The air preheater comprises a cylinder, an air inlet pipe is fixedly connected to the surface of one side of the cylinder, an air outlet pipe is fixedly connected to the surface of the other side of the cylinder, and preheating pipes are fixedly connected to the surfaces of the two ends of the cylinder; openings in the two ends of the preheating pipe are located in the surfaces of the two ends of the cylinder correspondingly, external threads are arranged on the side surfaces of the two ends of the cylinder correspondingly, a conical barrel is installed on the surface of one end of each external thread in a threaded mode, a smoke exhaust pipe is arranged on the surface of one end of each conical barrel, and a connecting barrel is installed on the surface of the other end of each external thread in a threaded mode; a pull rod is slidably mounted in the center of the interior of the preheating pipe, the surface of one end of the pull rod is located on the side surface of the connecting cylinder, the other end of the pull rod is slidably connected to the side surface of the conical cylinder, and a cleaning block is fixedly connected to the surface of one end of the pull rod so that the use convenience and stability can be greatly improved; and the preheating effect and the high cleaning efficiency are ensured.

Description

technical field [0001] The invention relates to the field of garbage incineration, and more specifically relates to an air preheater for high-temperature waste gas garbage incineration. Background technique [0002] In the process of waste incineration, in order to ensure the sufficiency and thoroughness of combustion, air needs to be introduced into the incinerator, and in order to ensure combustion efficiency, the air that is introduced is generally preheated to avoid affecting the internal temperature and ensure high-temperature combustion weight. [0003] However, most of the existing air preheater structures for waste incineration are simple plate heat exchangers, which not only need to install electric heating equipment for heating and heat exchange, but also cannot recycle high-temperature combustion waste gas, and the cost is relatively high. The heat exchange part is not conducive to efficient cleaning of the dust in the pipeline, and it is easy to remain, which no...

[0003] However, most of the existing air preheater structures for waste incineration are simple plate heat exchangers, which not only need to install electric heating equipment for heating and heat exchange, but also cannot recycle high-temperature combustion waste gas, and the cost is relatively high. The heat exchange part is not conducive to the efficient cleaning of the dust in the pipeline, and it is easy to remain, which not only reduces the service life, but also greatly reduces the heat exchange efficiency and affects the preheating effect, which needs to be improved
