Description
Technical field
The present invention relates to the production equipment of activated carbon, particularly to a kind of equipment using fluidization to produce activated carbon.
Background technology
Activated carbon is adsorbent, catalyst and the catalyst carrier that a kind of purposes is quite varied.Have at numerous areas such as food, sugaring, medicine, chemical industry, environmental protection, anti-, agricultural, fuel gas storage, gas separation, catalytic reactions and have been widely used.
The activated carbon industry of China from last century the fifties, the development course the most passed by more than 60 year.In this course, the main technique and the equipment that are used are all from the former Soviet Union, i.e. rotary furnace charing, and Stepple furnace activates.This technique and equipment account for more than the 90% of domestic aggregated capacity at present, improve although wherein carrying out some, but still do not have substantial variation.After entering 2000, expanding under the overall background with energy-conserving and environment-protective in the market demand, China has introduced multi-stage oven production technology and equipment.
Rotary furnace charing, Stepple furnace activating process: be processed into the coal grain of certain particle size or compressing billot; retort is added through bucket elevator or belt feeder; burner is heated by producer gas; heat smoke contacts with material in a counter-current configuration; being stepped up with temperature, order completes the processes such as pre-heating temperature elevation, drying and dehydrating, cracking charing.The carbonized material produced is discharged by stove afterbody, stores in a warehouse after cooling standby.Charing tail gas empties after waste heat boiler burns.The boosted equipment of carbonized material is added by Slapple activating furnace top, through the activation up to 50 hours high-temperature water vapors, furnace bottom discharges, i.e. finished product activated carbon.
Slapple activating furnace technique starts from the Europe of the '30s in last century, and early fifties introduces domestic, and after the eighties, spread uses at home.The huge construction cost of this process equipment not only external form is high, and power consumption is high, output is low, and does not has corresponding vent gas treatment facility, and specifically unit yields poorly.The equipment of maximum-norm also only reaches annual output 1500 tons at present, and this is also to cause the key factor that industry is disperseed, concentration degree is low.
Rotary furnace charing, multi-stage oven activating process: charing uses rotary furnace to complete, and carbonized material is added by multi-stage oven upper of furnace body, under stove arm straps is dynamic, successively moves down, contacts with high-temperature vapor in moving process, completes activation.
The shortcomings such as although multi-stage oven technique has had improvement in terms of energy consumption and environmental protection, but still existence is invested excessive, and maintenance cost is too high, and production cost is high.
The carbonized material of prior art needs all swivel links deposited through cooling, dress, transport after retort is discharged, and enters back into activation furnace, and production cost is the highest.
Stepple furnace and multi-stage oven can not be fully contacted due to high-temperature vapor and carbonized material during activating process, and the ratio of finished activated charcoal and high-temperature vapor is respectively 1:6～8 and 1:4～6, and energy waste is serious.
The output ratio of the finished activated charcoal of prior art is typically at 3.75 tons: 1 ton (wherein bunker coal 1.25t, feed coal 2.5t), and production cost is high.
At present, the activated carbon industry of China is high still in energy consumption, seriously polluted, unit yields poorly, cannot realize the situation that automatically controls, manufacturing cost is high, strongly limit the development of industry.This is the most unbecoming with the status of China's activated carbon manufacture and consumption big country.Tracing it to its cause, key factor is exactly the technique produced and equipment is not carried out updating, and still rests on the level of the forties in last century.
