A gas and hot water co-supply system coupled with biomass and carbon five auxiliary liquid

Abstract

The invention discloses a combined fuel gas and hot water supply system with biomass being coupled with pentane by-product liquid. The system comprises a biomass raw material bin, a crushing machine,a dryer, a stock bin, a biomass gasifier, a gasified gas cooler, a pentane by-product liquid storage tank, a water bath pentane by-product liquid vaporizer, a bypass water pipe, a water pipe valve, atubular air preheater, a purifying device, a gas flowmeter, a mixer, a gas compressor and a gas storage tank. The combined fuel gas and hot water supply system is a fuel gas supply system with the biomass gasified gas being mixed with pentane light dydrocarbon, according to the system, the biomass resource serves as a basic energy source, and the pentane by-product liquid serves as a supplement energy source; and in the gas supply system, the pentane by-product liquid is heated and vaporized through heat emitted by the biomass gasifier, the system heat is reasonably utilized, and in addition,the system can supply hot water at the same time.

Description

Technical field[0001]The invention relates to the field of biomass resource utilization, in particular to a gas and hot water co-supply system coupled with a carbon five auxiliary liquid of biomass.Background technique[0002]Rural areas are rich in biomass resources, such as straw, twigs, dry wood, wheat straw, etc. The traditional method of use is scattered burning, that is, each household collects the biomass resources in their own fields to store and burn them for cooking or heating. When burning, biomass fuel has low combustion efficiency and high pollutant emission, which causes energy loss and environmental pollution. With the progress of society, some rural areas are more inclined to use coal that is easy to store and have a higher calorific value, or even use electricity directly, thus giving up the use of local biomass resources and greatly wasting energy. There are also some areas that use biomass to develop biogas energy supply, but the supply of biogas is greatly affected...

Problems solved by technology

[0002] Rural areas are rich in biomass resources, such as straw, branches, dry firewood, wheat straw, etc. The traditional method of use is scattered burning, that is, each household collects biomass resources in their own fields to store and burn them for cooking or heating. The combustion efficiency of biomass fuel is low and the emission of pollutants is high, resulting in energy loss and environmental pollution.

With the progress of society, some rural areas are more inclined to use coal that is easy to store and has a higher calorific value, or even use electricity directly, thus giving up the use of local biomass resources and greatly wasting energy

There are also some areas that use biomass to develop biogas energy supply, but the supply of biogas is greatly affected by the seasons. When the biomass resources are insufficient or the demand for gas increases, the predicament of insufficient supply often occurs

However, the calorific value of biomass gasification gas is generally low, about 6MJ / Nm 3 , the lower calorific value of gas limits the use of biomass gasification gas as residential gas
