As can be seen from Table 1, it is suitable with the performance index of the gac that art methods obtains that the method that the utility model provides obtains the performance index of gac, and the gac that can substitute prior art is completely sold as commercial goods.
The equipment that the utility model provides is prepared furfural co-producing active carbon and is had huge economical effectiveness:
To prepare 1 ton of furfural as example, prior art is prepared after 1 ton of furfural, and remaining furfural dregs is without any economic benefit, and undressed furfural dregs can not arbitrarily discharge in order to avoid contaminate environment.The equipment that the utility model provides is prepared furfural can co-producing active carbon, can utilize efficiently furfural dregs to improve the recycle value of furfural dregs, has avoided the pollution of direct discharge furfural dregs to environment, has the higher value of environmental protection; Produce 1 ton of furfural, can produce the furfural dregs of 10 tons of left and right, the equipment that the utility model provides adopts 10 tons of furfural dregs at least can prepare 3 tons of gacs.
The phosphoric acid adding while preparing furfural almost all remains in furfural dregs, can give tacit consent to almost and not lose.When the equipment that adopts the utility model to provide is prepared gac, can reduce the phosphoric acid amount of adding afterwards according to the phosphorus acid content in furfural dregs.The all phosphoric acid adding is recovered in later stage acid recovery process, and the phosphoric acid amount of gac consumption per ton is about 250kg~300kg; But in the furfural preparation of traditional technology, the catalyzer of use is sulfuric acid, but sulfuric acid can not reuse; Existing technique is taking phosphoric acid as catalyzer, but phosphoric acid reuse.So existing technique can be thought not spent catalyst, save the cost of catalyzer, approximately 300 yuan/ton.
And prior art to prepare the producer of gac be taking wood chip, coal or shell as raw material, cost is at 2000 yuan/ton of gacs, and the equipment that the utility model provides to prepare gac be that to adopt discarded furfural dregs be raw material, there is no raw materials cost.The production cost of gac can reduce by 2000 yuan/ton.
When furfural production, can produce a large amount of exhaust steam, used heat, this part steam cannot store can only be emptying.And the equipment providing with the utility model is while preparing gac, need to be dried starting material and the gac of having washed.The exhaust steam of furfural just in time can be used to dry starting material and finished product.The reasonable utilization of exhaust steam, has reduced the production cost of gac effectively.It is 20% that the furfural dregs that 1 ton of water ratio is 70% is dried to water ratio, needs to consume the standard coal of 0.2 ton.Producing 1 ton of gac needs the furfural dregs of 2.5 tons of water ratio 20%, so need to dry the furfural dregs of 8 tons of water ratio 70%, produces 1 ton of gac and need consume 1.5 tons of coals oven dry starting material.And the exhaust steam, the used heat that produce during by furfural production collect effective utilization, can replace and dry raw-material 1.5 tons of coals, can reduce significantly like this production cost of gac.
From the analysis of above three aspects, the equipment that the utility model provides is prepared furfural co-producing active carbon can save a large amount of production costs, and has huge economic benefit.The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
