Abstract
The invention discloses a method for processing plant-based waste residue by utilizing cellulose and combining mechanical expression. The method comprises the following steps of uniformly mixing cellulose and plant-based waste residue, and placing the mixture at a room temperature, or preserving the temperature of the mixture for certain time, squeezing the uniform mixture by mechanical expression equipment so as to filtering the liquid part out, and drying the rest of the dry material by steam, and finally combusting the dried material. By adopting the method for processing the plant-based waste residue provided by the invention, more than 80 percent steam consumption is saved compared with that of the conventional processing method in which the plant-based waste residue is combusted after being directly dried by steam, and meanwhile, the processing time is shortened, and the production costs of manpower, electric power and the like are reduced.
Description
Technical field
The invention belongs to the offal treatment field, specifically, relate to a kind of cellulase that utilizes in conjunction with the method for mechanical expression process vegetal waste residue.
Technical background
Furfural mill, pharmaceutical factory, sugar refinery etc. have a large amount of vegetalitas waste residue generations after utilizing plant material to produce corresponding product at present, and some waste residue amount of one day of large-scale pharmaceutical factory is above 200 tons.Process these vegetalitas waste residues and need the expenses such as a large amount of human and material resources and place.Simultaneously, also because the higher distinctive foul smell of vegetalitas waste residue of water content causes its processed time to need to shorten as far as possible.The water content of vegetalitas waste residue is generally 70% ~ 90%, and directly squeezing is difficult to moulding, also can't directly burn.Traditional processing method be first with steam drying to water content 20% ~ 50%, again with squeezing or burn and to process.This conventional method need to use a large amount of steam to make its cost always high, and the long fast processing of not utilizing of drying time.
Summary of the invention
The object of the invention is to: provide a kind of cellulase that utilizes in conjunction with the method for mechanical expression process vegetal waste residue, utilize the principle of cellulose degraded cellulosic substrate, process in conjunction with drying and incinerating behind the mechanical expression equipment squeezing vegetalitas waste residue, the method can reduce a large amount of steam use amounts, and also reduces the resting period of waste residue large volume when reducing the production costs such as manpower, electric power.
Technical solution of the present invention is that this processing method may further comprise the steps:
(1) utilizes the pH to 3 of acid-base accommodation vegetalitas waste residue ~ 6;
(2) add cellulase in the vegetalitas waste residue of regulating pH, ratio is 0.001 ~ 0.5U cellulase/every gram waste residue;
(3) the mixed vegetalitas waste residue of cellulase is placed room temperature or 40 ~ 60 degrees centigrade of insulation a period of times;
(4) the vegetalitas waste residue after placement a period of time changes the squeezing of mechanical expression equipment over to, and pressure is 8 ~ 60kgf/cm
2
(5) the waste residue utilization steam convection drying after the squeezing;
(6) dried waste residue is put into incinerator or biomass boiler burning disposal.Wherein, the cellulase that adds in the vegetalitas waste residue described in the step (2) is the enzyme of degradable plant raw material.
Characteristic effect of the present invention is as follows:
1. in the preceding working procedure of dried plant waste residue, increased and utilized the cellulase waste residue of degrading, make the cell membrane of plant cell damaged, reduced working pressure and the dwell time in the mechanical expression operation time one.
2. increased the mechanical expression operation, waste residue weight reduces in a large number in this operation, and water is squeezed and extrudes in the cell.
3. because be the vegetalitas waste residue, in last burning operation, use biomass boiler to burn, but take full advantage of the value of vegetalitas waste residue.
