Abstract

The refuse fermentation treatment method includes the following steps: sorting the refuse, taking out recoverable refuse, placing other refuse into a fermentation chamber, feeding air into the fermentation chamber from its bottom to provide oxygen gas to ferment the refuse, and using a heap-turning machine to turn the refuse heap upside down every day or every second day, and moving the fermented refuse heap forwards at a distance, and converting the fermented refuse into organic fertilizer, and pumping the waste gas produced by fermentation into the incinerator to burn it.

Description

Rubbish fermentation treatment method

The present invention relates to a kind of rubbish fermentation treatment method, refer to especially a kind ofly make rubbish reach regeneration, and make the treatment process of waste reduction by fermentation.

Because the raising of economic level, people after having enjoyed high-quality life, relative generation a large amount of rubbish, and trash processing way now, except burying, still can burn by incinerator, no matter but bury or burn, all environment structure is polluted, ecology is changed, and therefore, above-mentioned treatment process is all undesirable, especially rubbish in small, broken bits make artificial be difficult for classification or the manual sort uneconomical, the place of problem especially.

Main purpose of the present invention is to provide a kind of rubbish fermentation treatment method, can make the rubbish after the fermentation become organic fertilizer, for regeneration.

Another object of the present invention is to provide a kind of rubbish fermentation treatment method, rubbish after fermentation can be divided into can ferment and can not ferment two portions, be beneficial to screening, and fermentable rubbish forms powdery, and there is not stink, can not fermentation part then be burned or be buried, quantity of refuse is reduced.

Another purpose of the present invention is to provide a kind of rubbish fermentation treatment method, and the waste gas (coal mine gas) that is produced when making fermentation can be evacuated to incinerator for its burning, and resource reclaims and the purpose of save energy to reach.

The object of the present invention is achieved like this, and a kind of rubbish fermentation treatment method promptly is provided, and rubbish divided into can be fermented and can not fermentation part, but make fermentation part become organic fertilizer, for regeneration, and make waste reduction, described method comprises: rubbish is dropped into a proving room; Send into the oxygen of air by the proving room bottom, impel its inner rubbish fermentation with supply proving room inside; With the input rubbish of proving room with a stack turner every day or stirred every other day, and push a segment distance forward; Can decompose and nondecomposable rubbish is screened with vibration screen, but and make and be decomposed into powder granulous decomposing organic matter and continue fermentation; Rubbish after the fermentation is made organic fertilizer, for regeneration.

Below in conjunction with accompanying drawing, embodiments of the invention are described, wherein:

Fig. 1 is a treatment scheme synoptic diagram of the present invention;

Fig. 2 is a stack turner structural representation of the present invention;

Fig. 3 is a Processing Example synoptic diagram of the present invention;

Fig. 4 is a stack turner action embodiment synoptic diagram of the present invention.

See also shown in Figure 1, the present invention mainly gives rubbish earlier and dropping on the conveying belt 11 set in the treatment chamber 1, and pick up callable rubbish with manual type, as plastic cement, vial or cardboard etc., again Other Waste is dropped in the proving room 2, make its fermentation, wherein the bottom of this proving room 2 is provided with several pores 21, to send into the oxygen in the air supply proving room 2, impel rubbish fermentation, the top then is provided with one can be vertical, laterally the stack turner 3 that moves is stirred rubbish, and push forward, make the rubbish after the fermentation become organic fertilizer, for regeneration (this moment, rubbish reached the decrement effect), the rubbish that can not ferment is wherein then delivered to the incinerator burning or is buried, and the waste gas that fermenting process produced (coal mine gas) can be extracted pipe 22 out via waste gas and extract out, to be made for the fuel of incinerator.

See also shown in Fig. 1,2, stack turner 3 of the present invention is provided with a support 31, the front end of this support 31 is articulated in a track type stirrer 35, and several up-and-down rods 351 side by side are set on the crawler belt of this stirrer 35, is constituted the turning effect to rubbish when this crawler belt is rotated.

See also shown in Figure 3ly, the present invention can comprise the steps: when actual treatment

1. rubbish is poured into the conveying belt of treatment chamber 1, reclaimed with the recyclable rubbish that manually will be easy to classify, and the rubbish that uses and pick easily of can not regenerating deals with in addition, other rubbish then drops into proving room 2.

2. send into air with the oxygen in the supply proving room 2 by the pore 21 of proving room 2 bottoms, impel inner rubbish fermentation, the waste gas that fermentation is produced is then taken out toward incinerator for burning by extraction pipe 22.

3. once input rubbish is stirred every day or two days with stack turner 3, and pushed a segment distance forward.

4. decomposable organism meeting slack is granular in the rubbish after the fermentation, nondecomposable rubbish then maintains the original state, both are screened with vibration screen 4, and decomposed rubbish continued to make its fermentation and become organic fertilizer (this moment rubbish decrement is many), nondecomposable rubbish is then delivered to the incinerator burning or is buried.

As shown in Figure 4, after rubbish fermentation was finished, this stack turner 3 can upwards be sling with hoist cable 36 by its bottom, and made its slippage backward, the taking-up of the rubbish finished of being beneficial to ferment, and the pending rubbish that drops into once more.

In sum, the present invention possesses following advantage at least:

1. resource reclaims again, makes rubbish reach the purpose of decrement, improves environmental pollution.

2. processing procedure is easy, and health.

3. the waste gas of fermenting cellar generation can for utilizing, fully reach the effect of resource recovery and energy savings.

4. can reduce the cost of labor of refuse classification.

Claims

1. rubbish fermentation treatment method is divided into rubbish and can be fermented and can not fermentation part, but makes fermentation part become organic fertilizer, for regeneration, and makes waste reduction, it is characterized in that described method comprises: rubbish is dropped into a proving room; Send into the oxygen of air by the proving room bottom, make its inner rubbish fermentation with supply proving room inside; With the input rubbish of proving room with a stack turner every day or stirred every other day, and push a segment distance forward; Can decompose and nondecomposable rubbish is screened with vibration screen, but and make and be decomposed into powder granulous decomposing organic matter and continue fermentation; Rubbish after the fermentation is made organic fertilizer, for regeneration.

2. the method for claim 1 is characterized in that, the bottom of described proving room is provided with several pores, for carrying air and supplying the oxygen of proving room inside.
