Abstract
The invention discloses one way of life rubbish biological dry disinfection technique, described house refuse biological drying sterilization process, be through sorting, pulverizing and hydraulic pressure dehydration by former house refuse, be then fed into the method that biological drying room is dried sterilization；Several steps such as including refuse classification, garbage crushing, hydraulic pressure dehydration, biological drying.One way of life rubbish biological dry disinfection technique of the present invention, adds active bacteria and is dried, and the moisture of the most removable 15% reduces drying cost, shortens the drying garbage time, improve the calorific value of rubbish, can increase the generated energy of rubbish for generating electricity；Can directly kill except most harmful bacteria.
Description
Technical field
The present invention relates to the processing technology field of house refuse, particularly relate to one way of life rubbish biological dry disinfection work
Skill.
Background technology
Along with the fast development of China's economy, the domestic waste yield of China increases day by day, the process of rubbish and place
Put and have become as the problem that China big and medium-sized cities must solve；China's municipal refuse annual production is about to 1. 5 hundred million tons at present, and
The most also increasing；How to realize that domestic waste is innoxious, " three change " of minimizing and resource processes and has become research
Focus.Sorting consumer waste is selected combustible constituent and makes fuel rod or pyrolytic gasification acquisition fuel gas, utilize burning combustion
The heat energy that charge bar or fuel gas obtain carries out generating electricity, bake bricks or other purposes those skilled in the art have been carried out research,
And achieve certain technological achievement.But in actual motion, still suffer from many problems, such as: house refuse made
Need before fuel rubbish is dried process, in conventional drying process, drying garbage relatively costly, anhydrate rate relatively
Low.So the MSW heating value after processing is relatively low, makes actual power generation be less than theoretical generated energy.Tongji University is 2007
Year apply for entitled " biological drying method of one way of life rubbish ", provided new thinking for house refuse dry, but its
Process engineering is complicated, expends the time longer, and drying cost is higher, and the method that there is no meets the actual application of high-volume domestic rubbish disposal
Demand.
Summary of the invention
It is an object of the invention to provide a kind of drying effect that can increase rubbish, reduce drying garbage cost, shorten
The drying garbage time, improve refuse thermal value, increase the house refuse biological drying sterilization process of generated energy.
The above-mentioned purpose of the present invention is realized by following technical proposal:
One way of life rubbish biological dry disinfection technique, described house refuse biological drying sterilization process, is by former house refuse
Through sorting, pulverize and hydraulic pressure dehydration, be then fed into the method that biological drying room is dried sterilization；
Specifically include following step:
1) refuse classification: sub-elect the inorganic matters such as the metal in former house refuse, glass, stone (inorganic matter is carried out reclaim and
Recycling), retain the Organic substance in house refuse；
2) garbage crushing: after sorting is gone inorganic matter, remaining organic domestic waste is put in pulverizer and pulverized, and makes domestic organic
The maximum particle diameter of rubbish is at below 8cm；
3) hydraulic pressure dehydration: the organic domestic waste after pulverizing is put into and carried out hydraulic pressure dehydration in hydraulic dewaterer, is allowed to moisture content
(moisture and the part by weight of total amount) is less than 50%；
4) biological drying: the organic domestic waste after step 3) being dehydrated is sent into biological drying room and carried out biological drying sterilization, will
The temperature of bacterium fermentation fever controls (to use high temperature resistant prebiotic bacterium colony) between 55 DEG C ~ 65 DEG C, makes organic domestic waste aqueous
Rate is less than 45%.
Further, the temperature of bacterium fermentation fever is controlled at 60 DEG C by described step 4).
The invention has the beneficial effects as follows: be greatly improved being dried and treatment effeciency of house refuse, make recyclable resource be closed
Reason utilizes；Wherein, the active bacteria added in biological dry room is dried, the moisture of the most removable 15%, thus reduces and be dried to
This, shorten the drying garbage time, and can directly kill except most harmful bacteria, and dry effect the most more preferably, improves rubbish
Calorific value, utilize this technique the calorific value of RDF made of dried rubbish material is higher, quality is more excellent, being used for generating electricity to increase
The generated energy of rubbish.
Accompanying drawing explanation
Fig. 1 is present invention process flow chart.
Detailed description of the invention
Carry out technical scheme detailed further below by embodiment, but protection domain is not limited to this.
Embodiment: one way of life rubbish biological dry disinfection technique, as it is shown in figure 1, house refuse biological drying sterilization work
Skill, is through sorting, pulverizing and hydraulic pressure dehydration by house refuse, is then fed into biological drying room and (refers to another entitled " a kind of raw
Thing dry disinfection room " patent application) method that is dried sterilization；
Specifically include following step:
1) refuse classification: sub-elect the inorganic matters such as the metal in former house refuse, glass, stone, inorganic matter is carried out reclaim and
Recycling, retains the Organic substance in house refuse；
2) garbage crushing: after sorting is gone inorganic matter, remaining organic domestic waste is put in pulverizer and pulverized, and makes domestic organic
The maximum particle diameter of rubbish is at below 8cm；
3) hydraulic pressure dehydration: the organic domestic waste after pulverizing is put into and carried out hydraulic pressure dehydration in hydraulic dewaterer, after hydraulic pressure dehydration
The moisture content (moisture and the part by weight of total amount) of organic domestic waste can be made less than 50%；
4) biological drying: the organic domestic waste after step 3) being dehydrated is sent into biological drying room and carried out biological drying sterilization, will
The temperature of bacterium fermentation fever controls (to use high temperature resistant prebiotic bacterium colony) between 55 DEG C ~ 65 DEG C, makes organic domestic waste aqueous
Rate is less than 45%.Add active bacteria to be dried, the most removable moisture of about 15%, reduce drying cost, when shortening drying garbage
Between, improve the calorific value of rubbish, the generated energy of rubbish can be increased for generating electricity；Can also directly kill except most harmful bacteria.
Wherein, the temperature of bacterium fermentation fever is preferably controlled in 60 DEG C by step 4).
Technical scheme in the present embodiment was carried out in Fujian Zheng Ren environmental protection company limited April 2015 November in 2014
Actual application, result shows: the drying cost of house refuse saves more than 20%, and drying time saves more than 14%.The effect being dried
Fruit the most more preferably, utilize this technique the quality of RDF made of dried rubbish material more excellent.
The foregoing is only the preferred embodiments of the present invention, be not limited to invention, although with reference to aforementioned enforcement
The present invention has been described in detail by example, and for a person skilled in the art, it still can be to foregoing embodiments
Described technical scheme is modified, or wherein portion of techniques feature is carried out equivalent.All invention spirit and
Within principle, any modification, equivalent substitution and improvement etc. made, within should be included in the protection domain of invention.
