Abstract
The invention discloses a process method for extrusion-packaging and semi-aerobic dehydration for domestic garbage, relating to a method for dehydration treatment for garbage, and aiming at solving the problems of complex process, long cycle, serous pollution and high cost in the prior art. The method comprises the following steps of: conveying domestic garbage to a drum screening machine, filling undersized matters in land, and conveying oversized matters to a waste paper packaging machine via a belt conveyer; performing extrusion-packaging on the garbage via the waste paper packaging machine, and enabling the water content of the garbage to be not higher than 40%; and stacking the garbage packaged blocks after the extrusion-packaging in an open space of a landfill, covering a waterproof cloth on the tops of the garbage packaged blocks, using concrete gratings for the bottoms of the garbage packaged blocks, forming a semi-aerobic natural fermentation state without mechanical ventilation, and enabling water in the garbage to be reduced less than 20%. Holes are arranged in the bottom and the sidewall of the waste paper packaging machine in the step b, the pressure of a main cylinder of the waste paper packaging machine is greater than 100 tons, and the power of the main cylinder is not less than 60 kW. The method is simple in process, pollution-free and low in cost.
Description
Technical field
The present invention relates to a kind of garbage dewatering processing method, particularly relate to a kind of process of carrying out processed to house refuse through extruding packing and half aerobic mode.
Background technology
In the domestic garbage resource treatment process, garbage dewatering is a vital link.Usually the moisture content of house refuse can exceed 5～10% in 50～60% scope in summer.Moisture content in the rubbish has reduced the calorific value in the rubbish, has increased the technical difficulty and the cost of garbage disposal.Different garbage as resource treatment process has corresponding requirement to msw water content:
Waste incineration and generating electricity---msw water content η≤50%;
Garbage derivatived fuel---msw water content η≤20%;
Refuse gasification cracking---msw water content η≤25%.
The conventional garbage dewatering process is following:
1. refuse-burning plant: rubbish was deposited in the storehouse 5～7 days naturally, and natural drop goes out a part of water and reburns.
2. drying roller technology is as shown in Figure 2:
The shortcoming of this technology is seriously polluted, and energy consumption is big, and cost is high.
3. fermentation cabin technology is as shown in Figure 3:
This technology floor space is big, spin cycle long (15～20 days).
Summary of the invention
It is long to the objective of the invention is to solve the complicated cycle of prior art processes, and seriously polluted is the high problem of cost, and a kind of house refuse extruding packing and aerobic dehydrating process partly are provided, and this method technology is simple, pollution-free and cost is low.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of house refuse extruding packing and half aerobic dehydrating process comprise the following steps:
A, house refuse is delivered to the rotary screen extension set, the screenings landfill, oversize is delivered to waste paper baler through belt feeder;
B, through waste paper baler with rubbish extruding packing, make msw water content not be higher than 40%;
C, with the rubbish enclosed mass piling on landfill yard vacant lot after the above-mentioned extruding packing, and cover waterproof cloth at the top, the concrete grid is adopted in the bottom, not through force ventilation, forms the partly state of aerobic spontaneous fermentation, treats that moisture drops to below 20% in the rubbish to get final product.
In technique scheme, the bottom of the waste paper baler among the said step b and side-wall hole, the pressure of the master cylinder of waste paper baler is greater than 100 tons, and power is not less than 60kw.
Can find out that from each item technical characterictic of the invention described above its advantage is: garbage dewatering technology cost of the present invention is minimum, and the cycle is short, and the moisture content in the rubbish is dropped to about 20%, has possessed the condition of carrying out step operation under the recycling treatment fully.
Description of drawings
The present invention will and combine the mode of instance to explain through the accompanying drawing comparison:
Fig. 1 is a process flow diagram of the present invention;
Fig. 2 is wherein a kind of technological process of production sketch map of prior art;
Fig. 3 is the another kind of technological process of production sketch map of prior art.
The specific embodiment
Through embodiment the present invention is done further explanation below in conjunction with accompanying drawing.
Preferred embodiment
As shown in Figure 1, process description of the present invention is:
A, house refuse is transported to material hole through loading machine, is transported to the rotary screen extension set through apron conveyer then, after screening, screenings is delivered to landfill yard through belt feeder, and oversize is delivered to waste paper baler through belt feeder;
B, through waste paper baler with rubbish extruding packing; The waste paper baler that adopts in this step is a common apparatus; Be used for rubbish is pushed packing, in the process that rubbish is extruded, the surface moisture major part of rubbish is extruded; Msw water content can be reduced to and is not higher than 40%, is equivalent to the dehydrating effect that rubbish stopped in fermentation cabin 5-7 days; In the process of extruding packing, help the rubbish draining in order to be more conducive to waste paper baler; We are employed on bottom and the sidewall of waste paper baler perforate or stay the slit; In addition; In order to reach better extrusion drainage effect, the pressure of the waste paper baler master cylinder of employing generally is greater than 100 tons, and its power is not less than 60kw.
C, with the rubbish enclosed mass piling on landfill yard vacant lot after the above-mentioned extruding packing, and cover waterproof cloth at the top, the concrete grid is adopted in the bottom; Not through force ventilation; Form the state of half aerobic spontaneous fermentation, in this process, the bacterium in the rubbish can take away large quantity of moisture after producing heat in this state; Portion of water is discharged from the bottom in addition, treats that moisture drops to below 20% in the rubbish to get final product.
Disclosed all characteristics in this specification except mutually exclusive characteristic, all can make up by any way.
Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
