A biomass boiler waste heat utilization device

Abstract

The invention discloses a waste heat utilization device of a biomass boiler, which comprises a hot water tank, the hot water tank is connected with a cold water tank through a connecting pipe, a continuous row of pipes extends into the hot water tank, and one end of the continuous row of pipes is connected with a continuous row of main pipes , the row of main pipes is connected with the row of tanks, the other end of the row of pipes is connected with the cold return pipe, the end of the cold return pipe extends into the cold water tank, the tap water branch pipe is connected to the cold water tank, and the first inlet extends into the cold water tank The water branch pipe, the industrial water inlet jellyfish pipe is connected to the first water return branch pipe through the first water inlet branch pipe, and the first water return branch pipe is connected with the industrial water return jellyfish pipe. In the present invention, the industrial water circulates in the first water inlet branch pipe, the water in the cold water tank absorbs the temperature of the industrial water, the boiler continuous sewage flows into the continuous drainage pipe, and the water in the hot water tank absorbs the sewage water The temperature of the water in the hot water tank is increased, and the water supplied from the connecting pipes flows into the cold water tank through heat release, which facilitates the collection of heat and reduces the loss of energy.

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
