Abstract

The invention discloses an intensive biomass pyrolysis gasification fuel gas purifying device which comprises a comprehensive absorption tower and a comprehensive separation tower, wherein the comprehensive absorption tower comprises a water cooling tower (1) at the lower part and an alkali spray tower (2) at the upper part, wherein the comprehensive separation tower comprises a gas-liquid separation tower (14) at the lower part and an adsorption tower (15) at the upper part; a water-cooled heat exchanger is arranged in the water cooling tower (1), and a tube plate net (8) is arranged at the upper part of the water cooling tower (1); and downward spiral-flow plates (20) are symmetrically arranged from top to bottom in the gas-liquid separation tower (14). By combining two tower, the functions of the two towers are integrated on one tower, and miniaturization and intensification of a biomass combustible gas purifying device are realized; and moreover, a relatively good purifying effect can be realized, and the investment cost and operation / maintenance cost are reduced.

Description

technical field [0001] The invention relates to a purification device, more specifically to an intensive biomass pyrolysis gasification gas purification device, which belongs to the technical field of biomass energy. Background technique [0002] Biomass energy is a form of energy in which solar energy is stored in organisms in the form of chemical energy, directly or indirectly derived from the photosynthesis of plants, and its sources include all plants, animals and microorganisms, as well as those derived, excreted and metabolized by these living substances. organic waste. The development and utilization of biomass resources is of great significance for protecting the environment, optimizing the energy structure, and alleviating the pressure on fossil energy supply. [0003] Biomass pyrolysis gasification technology can convert biofuel into bio-combustible gas that is convenient for transportation, storage and use. However, the obtained bio-combustible gas is crude gas, ...
