Description
Technical field
The present invention relates to building material technical field, especially relate to a kind of building block having domestic refuse to be prepared from.
Background technology
At present, the treatment process of domestic refuse rubbish is transported to be transported to refuse landfill again after garbage transfer station carries out compacting and carry out landfill, or deliver to garbage burning factory and burn, although process rubbish, but a series of problem is still many, the percolate of such as refuse landfill is easy to polluted-water, and foul smell pollutes the environment, and will take a large amount of soils etc.Garbage burning factory burning can produce Dioxins toxic gas and poisonous flying dust and poisonous residue.Therefore rubbish processing to be harmless, recycling is imperative.
Domestic refuse is pulverized after simple classification, has been reported for the field such as material of construction, plastic filler, but this or a thinking at present, and the method that there is no really is carried out.Because containing a large amount of bacterium, toxin in rubbish, also have strong stink, if do not addressed these problems, domestic refuse to be really applied in the life of people.
CN201210004494.1 provides a kind of method performing microwave pyrolysis on garbage, and under the microwave exposure of frequency 2450 ± 50MHz, structurizing rubbish is warming up to 350 ~ 650 DEG C and carries out cracking, then cracked gas and pyrolysis solid is recycled respectively.But this method is only directed to the organism in rubbish, obtain cracked gas and the solid of carbon containing, in domestic refuse, most of non-organic thing is not still utilized effectively.
Summary of the invention
For the problems referred to above that prior art exists, the applicant provides the heat preservation and soundproof building block that one way of life rubbish is made.Light block of the present invention can make garbage as resource utilize, and turns waste into wealth, economizes on resources, and for energy-saving and emission-reduction and refuse treatment provide good approach, solves the pollution of rubbish to environment, decreases taking land resources.
Technical scheme of the present invention is as follows:
The heat preservation and soundproof building block that one way of life rubbish is made, concrete preparation process is as follows:
(1) dry pulverizing after domestic rubbish disposal, 130 ~ 150 parts, rubbish after pulverizing, cement 100 ~ 120 parts, coal ash 120 ~ 130 parts, terra alba 3 ~ 4 parts, yellow ground 45 ~ 50 parts, water glass 1 ~ 1.5 part, 15 ~ 17 parts, calcium oxide, 50 ~ 60 parts, water are mixed, carries out vibrating and pressurizeing in mould compound being sent into automatic moulding brick press;
(2), after block forming, vapor cure 13 ~ 15 hours, curing temperature 85 ~ 95 DEG C, or natural curing 7 days, temperature 0 ~ 15 DEG C, makes the intensity of brick rise to 70% of design strength, then puts into finished product stockyard natural air drying and gets product.
Described building block can be light-duty or heavy building block.
Described domestic rubbish disposal is referred to domestic refuse is carried out disinfection, deodorizing process.
The method that the invention provides one way of life refuse treatment is: domestic refuse is put into feed reservoir, totally-enclosed control smelly, expect that by having driven a vehicle conveying belt enters first equipment primary election classification, second device processes is entered after vibratory screening, be transported to the 3rd equipment again after subseries to pulverize, enter in pond and clean with water roller, drift is pulled out sterilization and disinfection, carries out pressing dry or drying pulverizing.
The method that the invention provides another kind of domestic rubbish disposal is:
(1) prepare treatment solution: by ferrate with hypochlorite is water-soluble is mixed with treatment solution A, wherein the concentration of ferrate is 0.05 ~ 0.15wt%, and the concentration of hypochlorite is 0.2 ~ 1wt%; By boric acid, citric acid, oxalic acid is water-soluble is mixed with treatment solution B, and wherein the concentration of three kinds of raw materials is respectively 20 ~ 30wt%;
(2) pretreating waste: untreated rubbish is all put into gas explosion device, carries out steam explosion and comminution by gas stream, is become by garbage crushing particle diameter to be less than the particle of 5 ~ 10mm;
(3) microwave treatment: piled on the good rubbish of the pre-treatment of putting well than being sprayed at volume ratio 1:2 ~ 5 simultaneously by treatment solution A and treatment solution B, stacking is highly 30 ~ 50mm, then carries out microwave exposure, process 1 ~ 5 minute under the frequency of 915MHz; The volume of described treatment solution A and treatment solution B and be 1:3 ~ 10 with the ratio of the volume of described granulated garbage;
(4) then the granulated garbage after step (3) being processed stirs to stir stacks, stacking is highly 30 ~ 50mm, again spray treatment solution A and treatment solution B that volume ratio is 1:2 ~ 5, then carry out microwave exposure, under the frequency of 915MHz, process 30 ~ 180 seconds; The volume of described treatment solution A and treatment solution B and be 1:3 ~ 10 with the ratio of the volume of described granulated garbage;
(5) repeating step (4), until the mushroom content conformance with standard processing the rubbish obtained.
The technique effect that the present invention is useful is:
The technique effect that the present invention is useful is that the present invention has good Social benefit and economic benefit, has good effect to environment protection, and the part material utilizing rubbish to do product has saved cost, and rubbish of having dissolved, achieves many things at one stroke.Light block in the present invention is owing to make use of the fiber in rubbish so relative density is little, and quality is light, and the fibrous fraction in rubbish has the effect of drawknot cracking resistance, and the hollow structure of fiber has the effect of insulation.
Also added calcium oxide and water glass in the present invention, can kill the microorganism in rubbish further, water glass can increase speed and the intensity of formed product, and quality product is enhanced.Present invention utilizes the fiber in rubbish and chip, greatly reduce the cost of product.
In a preferred embodiment of the present invention, adopt treatment solution to spray and microwave radiation method, can the bacterium in rubbish, virus and peculiar smell, stink be removed simultaneously.Treatment solution of the present invention is Strong oxdiative thing and acids, very effective for sterilization Sum decomposition odor pollutant.Treatment solution and microwave combined effect can increase exponentially processing efficiency, sterilization and the deodorizing time short, process is thoroughly.
The present invention's method ground up the refuse used is steam explosion (being called for short " vapour is quick-fried ") method, is development in recent years a kind of pretreatment process rapidly.Raw material is with being steam heated to about 200 DEG C, and dimension pressure for some time, when unexpected release of pressure spurts, produce secondary steam, volume surges, under the effect of mechanical force, by solid materials structure deteriorate.This method used time is short, and treatment capacity is large, and processing efficiency is high, and takes sorting process apart without the need to the prior rubbish to being contained in refuse bag, is specially adapted to garbage crushing in enormous quantities.
