Abstract
The present invention relates to a kind of garbage treating and utilizing technological process. Garbage after being treated into dry grains is first mixed with coagulating and solidifying agent comprising magnesium chloride solution, magnesia, dilute sulfuric acid, ferrous sulfate and magnesium sulfate to form gelatinized material; and the gelatinized material is molded in a prescribed mold, cured for a certain time and then demolded to obtain the required building material. The process of the present inventino has relatively low throw-in and cost, and high economic and social benefit.
Description
The present invention relates to solid waste is processed into the technical field of useful materials, specifically a kind of garbage disposal utilizes technology.
According to statistics, municipal refuse every year increases with 3% speed approximately, and the rubbish that can not get handling occupies the soil, pollutes, and is constantly corroding human this narrow and small living space.The World Health Organization classifies garbage problem one of as ten human big problems of puzzlement.Human annual a large amount of fund that in disposal of refuse, spent.Aspect garbage disposal and utilizing, what generally adopt at present is methods such as classification is reclaimed, made compost, landfill, burning.More than each method exist and drop into many, the little deficiency of producing effects.
The object of the present invention is to provide a kind of technology simple, the daily-life garbage without environmental pollution processing and utilizing curing process that better produces effects arranged.
For achieving the above object, daily-life garbage without environmental pollution processing and utilizing curing process provided by the invention is:
After rubbish carried out disinfection, sorts out recyclable materials, remaining garbage disposal is become the dried particles of full-size less than 3mm;
Granulated garbage after the processing and condensation cure agent mix by weight 2～2.5: 1, fully stir into gelling dress base-material, and the condensation cure agent is made up of magnesium chloride solution, magnesia, dilute sulfuric acid, ferrous sulfate, magnesium sulfate mixing, and the percentage by weight of each component is:
Magnesium chloride solution 25～35
Magnesia 30～40
Dilute sulfuric acid 1～3
Ferrous sulfate 5～13
Magnesium sulfate 20～30
The Baume degrees of magnesium chloride solution is 20～25, and the Baume degrees of dilute sulfuric acid is 20～30.
Base-material as a form of gel is filled to predetermined in-mold molding, natural curing after 4～6 hours under 30 ℃ of temperature, the demoulding both required construction material.
The above becomes full-size less than the concrete scheme of 3mm dried particles to be garbage disposal: the waste incineration after will sterilizing, sorting, and to burn the back size pulverize greater than the caking of 3mm.
The condensation cure agent with handle after granulated garbage mix after, through neutralization-sintering-solidify-petrochemical process, finally can form hard material.
By such scheme as seen, daily-life garbage without environmental pollution processing and utilizing curing process provided by the invention can be produced some construction materials, and input and cost are less, and favorable economic benefit and social benefit are arranged.
Accompanying drawing is the process chart of the embodiment of the invention.
Below in conjunction with embodiment and process chart processing step of the present invention is further specified.
Earlier rubbish is carried out high-temperature sterilization with 100～110 ℃ of steam, then rubbish is sorted, the content of letter sorting mainly is by magnetic separation metal material to be chosen, and manually waste household appliances, other Recyclable is sorted out.To the rubbish screening after sorting, be divided into following a few class by the rubbish after the turn sieve screening: particle rubbish (full-size is less than 3mm) with turn sieve; Bulk rubbish; Software tablet (as melon and fruit peel, useless day plastics, rubber etc.).All kinds of rubbish to above-listed acquisition are handled respectively according to the following steps: (1) particle rubbish-drying, metering; (2) bulk rubbish-burning, broken slagging scorification (to full-size less than 3mm), metering; (3) software tablet-pick out plastics, rubber reclaim, to the moisture tablet of remainder pulverize, dehydration (sloughing 20～30% moisture content), burning, broken slagging scorification (to full-size less than 3mm), metering.
The drying garbage particle that above each step is obtained mixes with the condensation cure agent, fully stirs into gelling dress base-material.In the condensation cure agent, the best Baume degrees of magnesium chloride solution is 23, and the best Baume degrees of dilute sulfuric acid is 25, and the optimum weight percentage between each component is:
Magnesium chloride solution 30 magnesia 35 dilute sulfuric acids 2
Ferrous sulfate 8 magnesium sulfate 25
The optimum weight ratio of garbage drying particle and condensation cure agent is 7: 3.
Base-material is adorned in gelling be filled in the predetermined mould, natural curing is 4～6 hours under 30 ℃ of temperature, the demoulding, both required construction material.
Can produce multiple construction material by technology of the present invention, as, light wall board, floor tile, drainpipe, " U " shape tank etc.
