Continuous emission waste heat recovery equipment for boiler

Abstract

The invention discloses boiler continuous emission waste heat recovery equipment, and relates to the technical field of waste heat recovery equipment, the boiler continuous emission waste heat recovery equipment comprises a base, the middle part of the upper end surface of the base is fixedly connected with a barrel, the left end surface of the barrel is fixedly connected with a wastewater inlet pipe, the right end surface of the barrel is fixedly connected with a wastewater outlet pipe, and the front part of the outer side wall of the barrel is provided with a driving mechanism; supports are fixedly connected to the left side and the right side of an inner cavity of the barrel, a mixing mechanism is arranged between the supports located on the left side and the right side, and heat exchange mechanisms are arranged on the front side and the rear side of the upper end face of the base. According to the heat exchange device, heat of high-temperature waste water in an inner cavity of the barrel can be absorbed through the arrangement of the heat exchange plate, heat exchange liquid in a liquid storage tank can enter the heat exchange coil through a liquid inlet pipe by fixedly connecting the heat exchange coil with the heat exchange plate and starting an output pump, then the heat exchange liquid is discharged from a liquid outlet pipe, circulation of the heat exchange liquid is achieved, and heat exchange efficiency is improved. Therefore, the whole device realizes the function of recycling the waste heat of the waste water.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery equipment, in particular to a boiler continuous row waste heat recovery equipment. Background technique [0002] Industrial boiler products are divided into two types: steam or coal. In order to ensure the water quality of the steam boiler, the boiler needs to be continuously drained. The temperature of the drained water is the same as the saturated water temperature of the boiler. The blowdown consumes about 1% of the total energy. Part of the sewage is directly discharged, which not only causes heat consumption, but also pollutes the environment. Therefore, various waste heat recovery devices have appeared. [0003] However, the existing waste heat recovery device for industrial boiler wastewater has a complex structure, poor heat exchange effect and low heat exchange efficiency, which affects the heat exchange efficiency and the utilization rate of waste heat. Therefore, the presen...

Problems solved by technology

[0002] Industrial boiler products are divided into two types: steam or coal-fired. In order to ensure the water quality of the steam boiler, the boiler needs to be continuously discharged. Part of the sewage is directly discharged, which not only causes heat consumption, but also pollutes the environment, so various waste heat recovery devices have emerged

[0003] However, the existing waste heat recovery device for industrial boiler waste water has a complex structure, poor heat transfer effect, and low heat transfer efficiency, which affects heat transfer efficiency and waste heat utilization rate.
