Technical field
the utility model relates to a kind of refuse treatment plant, especially a kind of complexes that the biomass gas producing in refuse treatment is processed, specifically a kind of biomass gas deoxidation complexes.
Background technology
as everyone knows, take biogas, refuse embedded gas as the biomass gas of representative is the inflammable gas that is rich in methane, belong to renewable energy source, there is good value of exploiting and utilizing, and to improving topsoil, reduce greenhouse gas emission and there is important active effect.The utilization of China to biomass gas in the past, generating electricity by combustion in IC engine, boiler heats, be utilized as master as burnings such as stove aid burnings, along with the continuous of compressed natural gas used as vehicle fuel popularized, the mode of utilizing that biomass gas is purified to compressed natural gas used as vehicle fuel fuel becomes a development trend in recent years.
Biomass gas is prepared into compressed natural gas used as vehicle fuel fuel and has technically a difficulties, the compressed natural gas used as vehicle fuel fuel that meets national standard has strict demand to the oxygen level in fuel gas, must not be greater than 0.5%, and the biomass gas of collecting for reality, because often causing the oxygen level in gas, the factors such as leakage are greater than prescribed value, and existing biomass gas purification techniques (such as pressure-variable adsorption, wet absorption, membrane sepn etc.) is difficult to separate and removes oxygen components, this just causes the oxygen level value of gas after purification processes to exceed standard.
Summary of the invention
The purpose of this utility model is to serve as the problem that compressed natural gas uses because oxygen level exceeds standard for existing biomass gas, designs a kind of biomass gas deoxidation complexes that can effectively remove oxygen in biomass gas.
The technical solution of the utility model is:
A kind of biomass gas deoxidation complexes, is characterized in that it comprises:
One compressor 1, the inlet mouth of this compressor is connected with biogas source of the gas, and the biogas entering in compressor is pressurized to the pressure of 1-10 kilogram;
One well heater 2, this well heater 2 is for being heated to 150-400 ℃ to the biogas of process compressor 1 supercharging, and the inlet mouth of well heater 2 is connected with the air outlet of compressor;
The one catalytic deoxidation device 3 being formed by regenerator 301, adsorption bed 302 and catalytic bed 303, regenerator 301 reclaims catalytic bed 303 and exports heat for the biogas entering from well heater is further heated, to realize the heat self-balancing operation of catalytic bed;
One interchanger 4, this interchanger is lowered the temperature for the biogas that catalytic deoxidation device 3 is flowed out, and reclaims heat simultaneously, and the biogas after heat exchange is sent in follow-up refining plant.
