Biomass boiler waste heat utilization device

Abstract

The invention discloses a biomass boiler waste heat utilization device comprising a hot water tank. The hot water tank is connected with a cold water tank through a communicating pipe. A continuous blowdown pipe extends into the hot water tank. One end of the continuous blowdown pipe communicates with a continuous blowdown main pipe communicating with a continuous blowdown tank. The other end of the continuous blowdown pipe communicates with a cold water return pipe. The end of the cold water return pipe extends into the cold water tank, and the cold water tank communicates with a tap water branch pipe. A first water inlet branch pipe extends into the cold water tank. An industrial water inlet main pipe is connected with a first water return branch pipe through the first water inlet branchpipe. The first water return branch pipe communicates with an industrial water return main pipe. According to the biomass boiler waste heat utilization device, industrial water flows in the first water inlet branch pipe, water in the cold water tank absorbs temperature of the industrial water, boiler continuous blown down water flows into the continuous blowdown pipe, water in the hot water tankabsorbs the blowdown water, so that the temperature of water in the hot water tank is raised, and water in the continuous blowdown pipe releases heat and then flows into the cold water tank; and in this way, heat collection is convenient, and heat loss is reduced.

Description

technical field [0001] The invention relates to the technical field of biomass boilers, in particular to a biomass boiler waste heat utilization device. Background technique [0002] Biomass refers to various organisms formed through photosynthesis, including all animals, plants and microorganisms. Biomass energy is the energy form of solar energy stored in biomass in the form of chemical energy. It has always been one of the important energy sources for human survival, and it is the fourth largest energy source after coal, oil, and natural gas. plays an important role in the system. [0003] A biomass boiler is a type of boiler, and a boiler that uses biomass energy as fuel is called a biomass boiler. [0004] Biomass boilers are widely used in production and life. The flue gas of existing biomass boilers is mostly discharged directly into the atmosphere, and the dust in the flue gas will cause serious pollution to the environment. In addition, the flue gas discharged fr...

Problems solved by technology

[0004] Biomass boilers are widely used in production and life. Most of the flue gas of existing biomass boilers is directly discharged into the atmosphere, and the dust in the flue gas will cause serious pollution to the environment.

In addition, the flue gas discharged from the biomass boiler also carries a large amount of waste heat, and the waste heat of the flue gas is generally at 200-300°C, which leads to energy loss and a decrease in fuel thermal efficiency, which not only pollutes the environment but also increases production costs; the existing production The sewage discharged by the boiler is filtered and discharged. The temperature of the sewage discharged by the boiler is relatively high. Failure to collect heat will lead to energy loss and a decrease in fuel thermal efficiency; industrial water also has a certain temperature. Failure to collect heat will lead to energy loss and Reduced thermal efficiency of fuel
