Abstract
The present invention discloses a biomass gasification furnace absorbent and a production method thereof. The absorbent has a technical scheme comprising a principal point that the biomass gasification furnace absorbent is composed of attapulgite clay, high-Al alumina, magnesium oxide, calcium oxide, sodium carbonate and wood dust which are matched, stirred, ground, granulated, dried, screened, detected and packaged into a finished product which is used for an absorption filter of a biomass gasification furnace. When fuel gas output by the biomass gasification furnace flows through the granule absorbent, tar is further cracked. Heavy metals, alkali metals and harmful trace elements in fuel gas airflow are filtered and adsorbed. The tar which can not be cracked is dropped in a tar room and is collected by a U-shaped pipe. The biomass gasification furnace absorbent of the present invention has the advantages of low producing cost and convenient use, can be repeatedly regenerated and can not cause environmental pollution.
Description
Technical field:
The present invention relates to adsorbent, be specifically related to a kind of biomass gasification furnace absorbent and production method.
Background technology:
Early 1980s, China just begins that biomass thermal is decomposed gasification technology to be studied, and develops the gasification furnace of various ways.Living beings are a kind of regenerative resources, and reserves are very abundant, and using energy source as an alternative can realize CO
2Zero discharging, and S wherein, N content are low, alleviate greenhouse effects and environmental pollution greatly.
The biomass fuel essential element has C, H, O, N, S etc.: trace element has AI, Fe, Mg, Ca, K, Na, P etc.The living beings characteristic comprises that with different living beings kinds, different utilization part, growing environments the variation of soil, water quality, atmosphere changes.Living beings all must be through pyrolysis phase in the heat chemistry trans-utilization, and alkali metal and hazardous trace elements are separated out in the pyrolysis phase volatilization, along with the steam in the combustion gas, be condensate in heat-exchanger surface, be thick molten state, the solid particle in the captured gas, make particle agglomeration, cause the formation that deposits and cause the corrosion and the slagging scorification phenomenon of equipment, can cause that also gas pipeline silts up, produces serious influence to the biomass thermal conversion system, hinder heat exchange, reduce heat exchanger effectiveness.
The influence of heavy metal, in the biomass pyrogenation gasification process, solid pollutants such as lime-ash that gives off and flying dust discharge wherein trace heavy metal element and compound thereof thereupon, and these pollutants will produce serious influence to the ecological environment of atmosphere, water source and soil.
The cleaning system of present domestic biomass gasifying furnace, the method that adopts has: water-bath cooler, shutter inertial dust separator, normal temperature air condensation process device, plastic foam adsorption filter, the sawdust, shavings, gravel or the cobble that adopt the different grain size grade in addition are as absorption filtering material.
Chinese patent Granted publication CN2663811Y, Granted publication day is on December 15th, 2004, name is called " biomass gasifying furnace ", in patent document, illustrate " be provided with netted cobble chamber 13 at clarifier 2 internal upper parts; the indoor cobble 14 that is equipped with of this cobble; 13 bottoms, cobble chamber are provided with multilayer insulating panel 15; each dividing plate all has airflow orifice 16; and 16 one-tenth 180 ° of interlaced arrangement of the airflow orifice on the adjacent separator; as shown in the figure, when combustible gas enters the bottom of clarifier 2 in the body of heater 1,, form the zigzag air-flow stroke of combustible gas purifying is increased greatly through the airflow orifice 16 of dividing plate layer by layer, obtain thus just purifying preferably, continue to flow to cobble chamber 13 again, the space by cobble 14 makes the combustible gas that just purifies be divided into countless threads to carry out fast cooling, coagulate gas and fully purify, filter is assorted, obtain the gas outlet 8 of highly purified combustion gas to clarifier 2 at last, supply gas after the air of mechanism 3 mixes when this combustion gas and afterbody air distribution, can be that the user provides can clean-burning high-quality combustion gas.”
Utilize the space of cobble to make the combustible gas that just purifies be divided into countless threads and carry out fast cooling, but the smooth surface of cobble, hard, the effect that can not reach absorption and filter combustible gas.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, the biomass gasification furnace absorbent and the production method of a kind of low production cost, easy to use, good purification is provided
Biomass gasification furnace absorbent of the present invention is made up of Concave-convex clay rod, alumine, magnesia, calcium oxide, sodium carbonate, wood chip, detects and be packaged as finished product through batching, stirring, abrasive dust, granulation, oven dry, screening.
