Abstract
A waste incineration pre-treatment technological method for alpine underdeveloped areas comprises the steps of manual sorting of bulky crude waste, bag tearing and ice breaking, screening, magnetic separation and water seepage in a waste storage pit. In the step of manual sorting, the bulky waste is manually separated from waste; in the step of bag tearing and ice breaking, waste bags are torn, and ice blocks and ice lumps in the waste are broken up by beating; in the step of screening, the waste is screened into oversize products and undersize products; the undersize products are mainly composed of dust and are subjected to landfill treatment after magnetic separation, and the oversize products are fed into the waste storage pit for water seepage after magnetic separation; the ferrous metal obtained through magnetic separation is collected in a centralized mode for sale. The waste incineration pre-treatment technological method has the advantages that the ice blocks and the ice lumps can be fully melted after being broken by beating, so the water content of the waste put into a furnace is lowered; as the dust in the waste is screened out, the incineration heat value is increased remarkably; the fault rate of equipment can be lowered after the ferrous metal is removed from the waste put into the furnace; accordingly, the economic benefits of a waste incineration power plant are improved remarkably.
Description
Technical field
The present invention relates to technical field of waste treatment, particularly relate to waste incineration preconditioning technique.Specifically rubbish
Rubbish burning electricity generation factory house refuse enters the pretreating process of stokehold, is that one improves into stove waste incineration calorific value,
Solving high and cold low developed area rubbish in winter cannot the technique side of normal combustion technical barrier in incinerator
Method.
Background technology
In recent years, waste incineration and generating electricity processing mode develops rapidly, becomes China and processes domestic waste
One of main path.The house refuse of the extremely frigid zones that China is underdeveloped has the following characteristics that
1, rubbish ash is more, and calorific value is low, the most in the winter time Heating Period, and the content of dirt and frozen water is bigger,
Calorific value is lower；
2, China's extremely frigid zones, especially the Northeast, winter, outdoor temperature was the lowest, generally in subzero,
Containing substantial amounts of moisture more than kitchen in rubbish, in remaining meal, and being often in the state got wet, winter is at rubbish
Kitchen in rubbish bag is remaining, remaining meal becomes branch to freeze in bulk；
3, containing a certain amount of ferrous metal in rubbish.
The garbage incineration process of prior art enters after being typically moisture oozes out in garbage storing is cheated house refuse
Stove burns.Its deficiency is:
1, the incombustible inorganic matter of dirt composition system in rubbish, can make the combustion heat value of rubbish reduce, cause
Rubbish in incinerator can not normal ignition and burning, also act in Refuse Incineration Process prevention burning,
Absorb a series of negative interactions such as heat and abrasion fire grate, reduce the economic benefit of garbage incinerating power plant；
2, more than kitchen in refuse bag in the winter, remaining meal becomes branch to freeze in bulk.Due in garbage storing in winter hole
Temperature is relatively low, and more than the kitchen of the in bulk that freezes, the time of oozing out in garbage storing is cheated of the moisture in remaining meal composition greatly enhances
Other season, even make to cause combustion heat value to decline into stove rubbish because moisture is compared with other season more, occur
Rubbish can not the situation of normal combustion in stove.
3, the ferrous metal in rubbish can collide with fire grate, is even stuck in fire grate seam, causes shutdown thing
Therefore.
Summary of the invention
It is an object of the invention to provide a kind of high and cold low developed area waste incineration pretreatment process method, overcome existing
The deficiency of technology.
The technical scheme is that a kind of high and cold low developed area waste incineration pretreatment process method, bag
Include rubbish enter garbage storing hole before pretreatment, it is characterised in that: described rubbish enter garbage storing hole before pre-
Process includes part manual sorting step big to crude waste, broken bag trash ice step, screening step, magnetic separating
Step and garbage storing hole infiltration step, described part manual sorting step big to crude waste is big by rubbish
Part rubbish is manually isolated；Described broken bag trash ice step is by through the artificial rubbish broken bag trash ice separated
Machine tears refuse bag and the ice cube and the ice that smash in rubbish sticks together；Described screening step is by through broken bag trash ice step
Rubbish with sieve screening, be divided into oversize and siftage two parts, siftage based on dirt, oversize with
It is main for can burning away the refuse；Described magnetic separating step is the oversize and siftage screened step being sieved into
Carry out magnetic separating respectively, sub-elect the ferrous metal in oversize and the ferrous metal in siftage respectively,
Siftage after magnetic separating step sorts is transported to refuse landfill and is carried out landfill disposal；Walk through magnetic separating
Oversize after rapid sorting sends into refuse pit, makees water seepage treatment；On the sieve that magnetic separating step sub-elects
Sell after ferrous metal in thing and the ferrous metal centralized collection in siftage.
The present invention uses mechanical system to carry out the broken bag of refuse bag, by house refuse by the way of machinery impacts
In ice cube and ice stick together and smash, use the method for screening to isolate the dirt composition in rubbish, use magnetic separation
Ferrous metal in rubbish is removed by method.
The invention has the beneficial effects as follows: ice cube and ice stick together and is conducive to it fully to melt in garbage storing is cheated after being crashed to pieces
Changing, the water content entering stove rubbish reduces, and the dirt added in rubbish is sized out, so that it burns
Calorific value significantly improves；Enter after the ferrous metal in stove rubbish removes and just can reduce equipment failure rate；Waste incineration
The economic benefit in power plant will be significantly improved.
The present invention is applicable to during the garbage incinerating power plant winter built high and cold low developed area use.
Accompanying drawing explanation
Fig. 1 is present invention process flow chart.
Detailed description of the invention
The detailed description of the invention of the present invention is described below in conjunction with the accompanying drawings.
1, rubbish is transported to big part sorting platform by conveyer belt, carries out the artificial go-on-go of big part；
2, through the rubbish of go-on-go by conveyer belt to broken bag ice crushing machine feed, broken bag ice crushing machine by trash bag tear,
And the ice cube in house refuse and ice sticked together smash；
3, rubbish is evenly supplied rotary screen by conveyer belt, and the dregs in rubbish becomes siftage, and other one-tenth is divided into
For oversize；
4, the siftage containing a large amount of dregs is transported by conveyer belt after magnetic separating and concentrates, then transports to rubbish and fill out
Bury field landfill；
5, concentrate after the ferrous metal gone out through magnetic separating in siftage reaches some and sell；
6, oversize is transported to the garbage storing hole of garbage incinerating power plant after magnetic separating by conveyer belt, oozes
Water；
7, concentrate after the compressed packing of ferrous metal sorted out in oversize and sell.
