Abstract

The invention relates to a biological miasma pretreatment system for supplying miasma fuel to the generator or boiler. It is characterized in that: it comprises a desulfurizer (1), a water-cold miasma dewater device (2), a Root fan (3), a wind-cold heat emitter (4), a filter (5), an electromagnetic cut-off valve (6), and a channel fire arrester (7). The invention can solve the problems as corrosion and short service life.

Description

technical field [0001] The invention relates to a biogas treatment device, in particular to a biogas treatment device for providing qualified biogas fuel for thermal power plants, in particular to a biomass biogas pretreatment system. Background technique [0002] As we all know, the main component of biomass biogas is methane. As a strong greenhouse gas, its emission to the air is a great pollution to the environment. At the same time, methane is also a clean energy source, and it has been widely used in power generation, boilers, and pipeline gas supply abroad. With the development of my country's industry and agriculture and the acceleration of urbanization, industrial wastewater treatment, urban domestic waste landfill, agricultural and animal husbandry composting, etc. have brought abundant raw materials to the generation of biomass methane. At present, domestic biomass biogas utilization projects are in the ascendant, and related projects have been launched in more th...
