Description
Technical field
The utility model relates to the solid waste comprehensive utilization that produces in the industry of ammonia alkali legal system Sodium Carbonate Plant, particularly a kind of production line that utilizes the solid waste that produces in the Sodium Carbonate Plant industry to produce fat lime stone flour desulfurizing agent.
Background technology
At present, utilize ammonia-soda process to produce in the process of soda ash, mainly can produce three kinds of solid waste: sand return, return stone and rubble.Sand return is that lime stone does not change into emulsion through calcining and particle is less, after coming out from the sand return quarrel, directly catches with automobile, is put into the stockyard after walking.Return stone and be that lime stone does not change into emulsion through calcining and particle is bigger, after returning the stone quarrel and coming out, directly catch with automobile, be put into the stockyard at last.Rubble is stone through screening, and particle does not reach requirement, directly transports to the stockyard with automobile.Generally speaking, 1 ton of soda ash of every production needs 1.4 tons of lime stones, can produce 50 kilograms and return stone, 30 kilograms of sand returns and 90 kilograms of rubbles.The limestone resource utilization rate is 88%, and discarded rate is 12%.The Sodium Carbonate Plant sand return of middle and small scale, the annual production of returning stone and rubble can reach more than 90,000 tons, and after accumulation over the years, it measures big well imagining.In addition, be equivalent to be used for heap fortune with the cost of buying 12% lime stone and handle these discarded objects, waste great amount of manpower and financial resources.
Energy-saving and emission-reduction, cleaner production are demands of social development, also are the requirements of industry sustainable development.Along with the Environmental Protection in China rules are more and more stricter, these sand returns, return stone and rubble owing to can not get handling fully and utilizing, the long-term stacking is unpractical, must handle it eventually, and more late processing cost is more high.Sand return, the heap freight charges that return stone, rubble, land occupation resource expense and handling must cause the raising of alkali factory integrated cost, but also may cause environmental protection not pass a test.
At present, produce sand return in the soda ash process, return the comprehensive utilizating research of stone and rubble for ammonia-soda process, domestic and international rarely found report, main cause is that its contaminative, harmfulness are far below alkali factory exhaust gas discharged, waste liquid and alkaline residue etc.And for a long time, these solid waste are used for paving the way always or as the shaft kiln cement raw material etc., though value is very low, major part still can be consumed.And along with the eliminating of the raising that the road quality level is required and shaft kiln cement plant, the above-mentioned utilization rate of solid waste that alkali factory produces descends greatly, therefore, seeks new to utilize approach imperative.
The utility model content
The purpose of this utility model provides a kind of production line of desulfurizing agent, namely utilize the solid waste that produces in the Sodium Carbonate Plant industry to make desulfurizing agent, technology is simple, energy consumption is low, can produce CaO purity height, active high, fat lime stone flour desulfurizing agent that impurity is few, turn waste into wealth, reduce production costs greatly, compliance with environmental protection requirements.
The technical solution of the utility model is: a kind of production line of desulfurizing agent, comprise successively feed hopper, dryer, disintegrating machine, ball mill and the finished bin of arranging, between described feed hopper and the dryer, be respectively equipped with for the belt conveyor that transmits material between described dryer and the disintegrating machine; The material outlet of described disintegrating machine is connected to the material inlet of ball mill, and the material outlet of described ball mill is connected to finished bin.
