Method and device for collecting, separating, purifying and cleaning new energy by utilizing carbon making waste gas

Abstract

The invention discloses a method and a device for collecting, separating, purifying and cleaning new energy by utilizing carbon making waste gas. In the method, carbon making smoke gas sequentially passes through a waste heat boiler, a pyroligneous liquid separating device and two level woodtar separating devices so as to separate pyroligneous liquid and woodtar in the carbon making smoke gas and obtain purified combustible gas. The device comprises the waste heat boiler (2), the pyroligneous separating device (3), a one-level woodtar separating device (4), a two-level woodtar separating device (5), a blower (6) and a water block (27) which are sequentially connected through pipelines (1). The waste heat boiler (2) is provided with a smoke gas inlet (7), and the water block (27) is provided with a purified combustible gas inlet (8). The invention utilizes purified waste smoke gas produced in the carbon making process to generate electricity, and also extracts pyroligneous liquid and woodtar in the waste smoke gas as raw materials of other industries, thereby being an energy recycling industry chain system engineering, turning waste into treasure and reducing the energy consumption.

Description

technical field [0001] The invention relates to a collection, separation and purification method and device, in particular to a method and device for collecting, separating and purifying environmentally friendly new energy by using carbonized waste gas. Background technique [0002] At present, the production process of the charcoal industry is to put the pressed wood or sawdust sticks into the charcoal kiln, so that the wood or sawdust sticks are burned in the absence of oxygen to make charcoal. A large amount of flue gas will be produced during the carbon making process. In the past, these flue gases were directly discharged into the atmosphere, causing serious pollution to the atmosphere. The carbon making industry has become a major environmental polluter. In order to use the flue gas produced by these charcoal-making processes to generate electricity, it is necessary to remove impurities, wood vinegar and wood tar in the flue gas before it can be used.
