Abstract

The utility model discloses a rubbish compost electric generation device, which can be used to load rubbish into a reactor with inner walls made of cement. The device can fulfill organic matter fermenting during course of operation. On a base of the reactor, a plurality of air feed holes arranged in sequence are provided to charge marsh gas into an exhaust port, so that the rubbish can be separated from air and degradation can be accelerated in anaerobic environments to create compost finally that can be used to improve earthness; Marsh gas created during germ fermenting process goes through an upper duct of the reactor at its exhaust port, so that most of the marsh gas can be delivered into a purification release device. Methane and carbon dioxide can be produced through decomposition of different gases utilizing their differences in permeability; the methane will be sent into a steam turbine to generate electrical power; the carbon dioxide is exhausted from the lower part; small volume of marsh gas can be used in the next treatment process. The rubbish compost electric generation device has advantages of saving investment, small occupied area, high resource recovery rate, being safe and reliable and having no secondary pollution, for which the utility model becomes the most suitable rubbish treatment device with reclamation foreground.

Description

The garbage compost power generation assembly

One, technical field:

The utility model relates to a kind of power generation assembly, specially refers to a kind of garbage compost power generation assembly.

Two, background technology:

In the historical long river of human development, people will produce a large amount of rubbish unavoidably in the process of producing and living.These domestic refuses and waste residue are one of the most deleterious pollutents now.They enter the river course, silt the river up, influence shipping; Enter the farmland, reduce crop yield; It is burned power consumption and poisons air.Because growth in the living standard, the thing that people abandon is more and more, and the speed that produces rubbish is more and more faster, and refuse pollution is more and more serious.At the severe situation that refuse pollution is on the rise, each state is all solving this difficult problem by every means.Heat energy or generating can be produced by burning away the refuse, but the greenhouse gases polluted air can be discharged, and processing and running cost height.And land-fill method may pollute near soil.The purpose that requires refuse treatment should be innoxious, minimizing, resource utilization, environment and source of finance is all benefited making it.

Three, summary of the invention:

At above-mentioned situation, the purpose of this utility model is to provide a kind of like this garbage compost power generation assembly, it is the resource recovery comprehensive utilization technique of collection environmental protection and energy development one, rubbish is placed in the reactor that inwall water mud makes, make rubbish and air insulated, accelerated degradation in anaerobic environment has several to arrange orderly aperture and crosses the biogas of pressurization from these apertures injection arrival outlets on the pedestal of reactor.This process needs three time-of-weeks, degrades fully up to rubbish, finally produces high-quality compost and biogas, and compost can bring organic soil ulmin for the soil, improves because agricultural is strengthened the barren phenomenon in soil that farming causes.The biogas that produces in the process of fermentation using bacteria is delivered to decontaminating separator through the reactor upper catheter with most of biogas in the exit, in this device, utilize gas with various that the infiltrative difference of material is resolved into methane and carbonic acid gas with biogas, methane is delivered to turbine generator through gas duct go generating, through transformer electricity is offered the user again, small portion is delivered to next handling procedure through pressurization biogas.The major advantage of this device is:

1, low, the less energy consumption of efficient height, expense, non-secondary pollution;

2, take up an area of less, reduced investment, resource recovery rate height;

3, simple to operate, easy to maintenance, level of automation is high;

4, stable, safe and reliable.

Four, description of drawings:

Figure is the structural representation of the utility model garbage compost power generation assembly.

As shown in the figure, reactor (1) one side upper part is provided with rubbish import (16), lower part is provided with compost outlet (17), reactor (1) base is provided with the orderly injecting hole (3) of several arrangements and is used to inject biogas, reactor (1) makes rubbish fermentation in the process of running, produce biogas and compost (15), termination outlet pipe (4) on the reactor (1) also is connected to the bottom of some decontaminating separators (8) side by side through pump (5), so that biogas is delivered in this separator (8), utilize gas with various to the infiltrative difference of material, biogas is resolved into methane and carbonic acid gas, the gas duct (9) that methane is drawn by separator (8) top is sent into it in turbo-generator (10) and is generated electricity, and by transformer (11) electricity is offered the user.The bottom of vapor pipe (7) the relief outlet decontaminating separator (8) that the carbonic acid gas that produces in the separator (8) is drawn by the bottom is drawn recirculation pipe (6) and is incorporated in the pipeline (4), so as in the separator (8) not thoroughly the biogas of purification separation proceed to decompose.The last the other end of reactor (1) picks out and on the feed channel (14) flow rate control device (2) is housed so that the effusive flow of reactor (1) is controlled, and in reactor (1), inject biogas through the gas injection port (3) that pump (13) connects several ordered arrangement, make rubbish and air insulated, in anaerobic environment, quicken rubbish fermentation, rubbish in the reactor (1) is discharged by relief outlet (17) through the high-quality compost (15) that the running of three weeks produces, and is used to improve soil property.Counter (12) also is equipped with in the outside of device, can operate control to the state of whole device.

The biogas that rubbish produces both can be used for generating, peripheral region heat supply when can be used as fuel again, and the compost that rubbish produces can bring organic soil ulmin for the soil, improves because agricultural is strengthened the barren phenomenon in soil that farming causes.Garbage compost generation technology maturation, environment and economic benefit are obvious, have wide developing prospect.

Claims

1, a kind of garbage compost power generation assembly, mainly comprise reactor (1), decontaminating separator (8), turbine generator (10) etc., it is characterized in that reactor (1) base is provided with the orderly biogas inlet (3) of several arrangements and is used to inject biogas, arrive outlet, degraded through three weeks, the final high-quality compost (15) that produces, termination outlet pipe (4) on the reactor (1), and be connected to the bottom of some decontaminating separators (8) side by side through pump (6), so that biogas is delivered in this separator (8), utilize gas with various to the infiltrative difference of material, biogas is resolved into methane and carbonic acid gas, the gas duct (9) that methane is drawn by separator (8) top is sent into it in turbo-generator (10) and is generated electricity, and electricity being offered the user by transformer (11), the vapor pipe (7) that the carbonic acid gas that produces in the separator (8) is drawn by the bottom is discharged.
