Embodiment 1

[0028] A method for tar purification treatment, comprising the following steps:

[0029] (1) The crude gas 3 from the outlet of the gasifier 1 enters the cooling scrubber 4, cools and removes tar, and obtains a clean gas 6;

[0030] (2) The tar waste liquid flows into the first circulating water tank 5, and the first circulating water tank 5 communicates with the second circulating water tank 8, and the tar waste liquid 7 enters the second circulating water tank 8 from the first circulating water tank 5, and is cooled by the circulating water cooler 9 After that, re-enter the cooling scrubber 4 to cool, wash and purify the crude gas 3, forming a cycle;

[0031] (3) The gasification agent 11 passes through the tar waste liquid 7 in the second circulating water tank 8 , and the gasification agent 10 carrying the volatilized tar waste liquid enters the gasifier 1 and reacts with the biomass 2 to generate the crude gas 3 .

[0032] (4) The furnace body of gasifier 1 is lengthened...

Abstract

The invention discloses a tar purification treatment method and system. The method comprises the following steps that (1) tar-containing crude gas of a gasifier outlet enters a cooling washing tower to obtain a tar waste liquid and clean gas; (2) the tar waste liquid treated by the cooling washing tower flows into a circulating water tank, is cooled by a circulating water cooler and then enters the cooling washing tower again to cool, wash and purify the tar-containing crude gas, and the purification cycle of the crude gas is formed; (3) a part of a gasifying agent enters a gasifier and reactswith biomass to generate the crude gas, the other part of the gasifying agent passes through the circulating water tank, and the gasifying agent carrying the volatile tar waste liquid enters the gasifier and reacts with the biomass to generate the crude gas. The tar purification treatment method and system have the advantages that the good volatility of tar is utilized, the gasifying agent required for the gasifier is introduced into a tar waste liquid tank, and the gasifying agent carrying the volatile tar waste liquid enters the gasifier to participate in a gasification reaction together, thereby avoiding the problem of tar waste liquid treatment, and recycling tar energy.

Description

Technical field: [0001] The invention belongs to the technical field of biomass thermochemical conversion, and in particular relates to a tar purification treatment method and system. Background technique: [0002] Biomass gasification is the conversion of solid biomass fuel into gaseous gas. Biomass is converted to combustible gases such as hydrogen and carbon monoxide by reacting with oxygen and / or water vapor under high temperature conditions. The combustible gas produced by biomass gasification can be used for centralized gas supply, to replace fossil fuels in industrial boilers / kilns, to generate electricity or to synthesize liquid fuels. It has a wide range of uses and broad application prospects. [0003] The tar contained in the gas can cause scaling, blockage and corrosion of pipelines and downstream equipment, affecting system operation and safety, and is a bottleneck that restricts the popularization and application of gasification technology. Common tar removal...
