A device for boiler waste heat recovery

Abstract

The invention relates to the technical field of boilers, and discloses a device for boiler waste heat recovery. The device comprises a boiler body, wherein a chimney is fixedly connected to the top part of the boiler body; an air guiding pipe is fixedly connected to the top part of the chimney through a seal sleeve; a heating chamber is fixedly connected to one end, far away from the seal sleeve,of the air guiding pipe; a water tank is fixedly connected to the top part of an inner wall of the heating chamber; a discharge pipe is fixedly connected to one side, far away from the air guiding pipe, of the heating chamber; and one end, far away from the heating chamber, of the discharge pipe is fixedly connected to the top part of a side face of a cleaning chamber. According to the device forboiler waste heat recovery provided by the invention, waste heat discharged by the boiler body can be conveniently guided into the heating chamber through the air guiding pipe, and the collected wasteheat is fully used for heating the water tank in the heating chamber, so that the waste heat produced by the boiler body can be reutilized; and through the cleaning chamber, impurities in sewage canbe conveniently cleaned, so that the pollution of the sewage on the environment is prevented, and an environment protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a device for recovering boiler waste heat. Background technique [0002] The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace, or converts mechanical energy into electrical energy through a generator. The boiler that provides hot water is called hot water. Boilers are mainly used in daily life, and also have a small amount of application in industrial production. Boilers that generate steam are called steam boilers, and are mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises. [0003] In the process of boiler heating, a large amount of heat is used reasonably. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, ...
