Description

A kind of coupling prepares the system without tar coal gas and calcium carbide

Technical field

The utility model is related to calcium carbide technical field of smelting, and in particular to a kind of coupling is prepared without tar coal gas and calcium carbide System.

Background technology

The coking of coal, gasification, synthesis calcium carbide process, for organic chemical industry's industry provides abundant crude benzol, tar, coke oven Gas, synthesis gas and acetylene, are three core pathways of Coal Chemical Industry.At present, coking of coal technological investment high cost, product purification be not Foot, added value of product be not high.Coal Gasification Technology progress is slow, efficiency is low, small scale, industrialization level are low.And synthesize calcium carbide Technique, route is simple, added value of product is high, good in economic efficiency, has been carried out large-scale industrial production, is that one kind compares and has hair Open up the clean coal technology of potentiality and the approach of Coal Chemical Industry.The calcium carbide (i.e. acetylene) of preparation can be used to synthesize benzene, rubber, polychlorostyrene second The organic products such as alkene, polyacetylene.Compared with oil ethene route, coal synthesis calcium carbide has that raw material sources are extensive, cheap, sets The low advantage of standby investment.Also, acetylene is higher than ethylene action, more conducively the carrying out of organic synthesis.

At present, calcium carbide synthetic method is mainly electrothermal way.The method converts electrical energy into heat energy by electric arc furnaces, and heating is molten Melt lime and carbon raw coke, combination reaction occurs and produces calcium carbide.Electrothermal way is with a long history, with high energy consumption, high pollution Shortcoming.Calcium carbide synthetic reaction is the solid phase endothermic reaction, and raw material mass-and heat-transfer efficiency is low, the chemical dynamics process time it is long, it is necessary to The heating of (2000~2200 DEG C) of high temperature, and high activity coke as raw material.The high temperature heating conditions need substantial amounts of energy, right The heat resistance requirement of equipment is high, and increased cost of investment and energy consumption.Raw coke is typically obtained by the coking of coal, flow Long, organic carbon depletion is high, power consumption is high, environmental pollution is serious.In order to improve containing for calcium carbide in lime-calcium carbide congruent melting speed and product Amount, typically lime excess 20wt% (wt% is mass percent) is required in practical operation, and material consumption and energy consumption are larger.Accessory substance one Carbonoxide effusion reaction system has taken away substantial amounts of heat, causes energy loss.

The electrical efficiency and the thermal efficiency for improving furnace of calcium carbide are to reduce the power consumption in calcium carbide production at present, and improve capacity usage ratio Two big countermeasures.But, calcium carbide is generated with coke direct reaction because electrothermal way technique is based on lime, it is the solid phase endothermic reaction, Improving electrical efficiency and the thermal efficiency anyway cannot all change the technique high energy consumption, high material-consumption, the present situation of high pollution.In order to improve Calcium carbide production energy, the greenization and sustainable development of realizing calcium carbide production, it is necessary to reform electrothermal way synthetic route, using new Calcium carbide synthesis technique and synthetic method.

Gently the gasify amount of byproduct semicoke of generation of coal accounts for 60~90wt% of product.Semicoke is carried out it is economical, Utilization effectively and reasonably, will improve the economy of whole process, and realize industrialization.Wherein, the property of semicoke is depended primarily on The species of coal, ash content and reaction condition etc..

In down-flow fluidized bed using ECT gasification reaction, coal dust autopneumatolysis furnace roof portion is sent into by induction system, with the gasifying agent being passed through by top It is parallel to move downward and haptoreaction, can typically stop the time of several seconds.In the course of reaction, gasification temperature is relatively low, coal dust exists The residence time is shorter in gasification furnace, efficiency of carbon con version is relatively low, contain a large amount of unreacted carbon in residue after gasifying.It is with vapor During gasifying agent, after gasification reaction production hydrogen-rich synthetic gas are carried out in a low temperature of 950 DEG C, (gasification is residual for solid product gasification char Slag) in the still carbon containing 60wt%.At present, gasification char is generally used for combustion power generation, and the level of resources utilization is relatively low.

Middle low-order coal reactivity is higher, rich in volatile matter, is gasified at relatively low temperatures and pressures, can produce more Tar.Influence of the tar to gasification system and gas equipment be：1. coal gas of high temperature carry tar in course of conveying gradually Condensation, is attached on pipeline and equipment inner wall, makes line clogging, containing alkali metal or alkaline-earth metal in tar, meeting etching apparatus, Influence system safety operation.2. contain more polyoxybiontic aldehydes matter in gasification tar, cause secondary waste water to pollute.3. gasify burnt Oil accounts for 3~10wt% of coal for gasification total amount, greatly reduces gasification efficiency, tar and gas fuel burning under cryogenic conditions Not exclusively, the badly damaged combustion gas of the carbon black of generation utilizes equipment, and wastes the energy.Therefore, simple gasification power generation system, it is desirable to Tar content is in 20~50mg/Nm³In the range of；Combustion system, it is desirable to which the content of tar is less than 10mg/Nm³；Production of methanol, It is required that the content of tar is less than 0.1mg/Nm³.To realize the target of low-rank coal in low temperature gasification treatment, it is necessary to study gasification Jiao The removal methods of oil.

There is research to point out, semicoke can be as new tar cracking catalyst or catalyst carrier.Semicoke is to tar Removing has catalysis activity very high, and when the gas containing tar is by hot semicoke bed, most of coke tar cracking produces gas Body and water.At 950 DEG C, tar is almost completely converted into low-BTU gas in semicoke.
