Description

A kind of refuse treatment plant based on low-temperature waste heat power generation equipment

Technical field

The utility model belongs to rubbish autohemagglutination pyrolysis technique field, more particularly to a kind of based on low-temperature waste heat power generation equipment Refuse treatment plant.

Background technology

Current most domestic city and county town substantially handle domestic waste with land-fill method.It is characterized in throwing Money small scale, technique is simple, be easy to build.But drawback one is that landfill yard will take the land resource of a large amount of preciousnesses, and two be to fill out reason Serious secondary pollution will be caused to environment after several years：The rotten produced continuous polluted underground water source of effusion of garbage corrosion, The methane gas that the rubbish fermentation that is landfilled is produced easily triggers blast, foul smell can have a strong impact on big compression ring around refuse landfill Border.Its basic reason is that landfill process can not thoroughly solve antiseepage, anti-stench, explosion-proof, landfill gas (biogas) utilization, percolate The problems such as processing.The drawbacks such as its polluted source, polluted agricultural land, soil, pollution air gradually appear, and have a strong impact on city and defend Raw environment, harm people's is healthy.Land-fill method processing rubbish can not also accomplish innoxious, minimizing, recycling, it is impossible to Meet the requirement that country handles townm refuse standard and environmental protection.

The mode of application of city life garbage processing is outer except landfill, also composting mode and burning mode.Composting mode is in composting During deodorization, carbon-nitrogen ratio, fermentation temperature control and do not solved very well the problems such as pre-treatment, particularly compost by In not to the effective classification of rubbish, containing glass, ceramics, inorganic matter fragment, plastics, rubber even refuse battery etc. in compost, it is not inconsistent Close national standard and agriculture ministerial standard.Some compost fail effectively high-temperature sterilization, and Fertilizer nutrient composition is not enough, is referred to as by peasant " refuse soil ", product is substantially unsalable, without market.

Some big cities handle rubbish using waste incineration mode, and one is that investment is big, ton investment average more than 650,000 yuan, And combustion-supporting with oil, coal, operating cost remains high, and very heavy financial burden is brought to government and enterprise, two be at rubbish It is generally grate furnace, fluid-bed combustion furnace to manage equipment, and many supporting imperfections, the flue gas after waste incineration does not often reach national mark Dioxins materials are exceeded in alignment request, particularly garbage burning factory flue gas, and the reproducible utilization rate of rubbish is low, most of rubbish Rubbish burning electricity generation factory bad economic results.

Using rubbish itself heat energy isolation handle rubbish technology be current World Developed Countries progressively use new one For technology of garbage disposal.But prior art is not utilized effectively to purifying smoke, resource, energy waste are there is, it is overall The problem of equipment inadequate energy-conserving and environment-protective.

Therefore, invent a kind of refuse treatment plant based on low-temperature waste heat power generation equipment and seem very necessary.

Utility model content

In order to solve the above-mentioned technical problem, the utility model provides a kind of garbage disposal based on low-temperature waste heat power generation equipment Equipment, is not utilized effectively to purifying smoke with solving prior art, there is resource, energy waste, integral device is inadequate The problem of energy-conserving and environment-protective.A kind of refuse treatment plant based on low-temperature waste heat power generation equipment, including pyrolysis chamber, flue gas passageway, mistake Aquaporin, crosses cigarette channel, purification separation device, purification gas delivery casing, defeated cigarette channel and cogeneration unit, and described crosses water Passage and excessively cigarette channel are connected by flue gas passageway with pyrolysis chamber；Described purification separation device one end connected cigarette channel, separately The described purification gas delivery casing of one end connection；Described cogeneration unit is connected by defeated cigarette channel and purification gas delivery casing Connect；Described purification separation device includes the defeated chamber of flue gas point, the defeated chamber of purification collection and gas cleaning chamber, and the described defeated chamber of flue gas point connects Take over cigarette channel；Described gas cleaning chamber connects defeated cigarette channel；The described defeated chamber of purification collection is arranged on flue gas point defeated chamber and cigarette Between gas purification chamber.

Described pyrolysis chamber subsection setup, described pyrolysis chamber is divided into disengagement chamber from top to bottom, and gas flash burn room is weary Gasification room and burning chamber.

Ignition temperature is less than 300 DEG C in described disengagement chamber, most of organic matter is divided in gaseous form from rubbish Separate out and, and enter in gas flash burn room.

Described gas flash burn Indoor Combustion temperature is more than 600 DEG C, makes organic matter by thorough combustion oxidation, eliminates Er Evil The material conditions (bioxin of English generation is that organic matter and chlorine element are generated at 300 DEG C -600 DEG C by complex chemical reaction, low In 300 DEG C of difficult synthesis, it can be decomposed higher than 600 DEG C).

Described water passage and cigarette channel excessively is connected especially by flue gas passageway with disengagement chamber.

Flue gas passageway is also associated between described water passage and mistake cigarette channel.

Described cogeneration unit uses ORC low temperature heat energy generating sets, is conducive to generating electricity using the flue gas after purification, And then power network is used by oneself or connected for the refuse treatment plant, produce economic benefit.

Compared with prior art, the utility model has the advantages that：Due to of the present utility model a kind of based on low The refuse treatment plant of temperature cogeneration equipment is widely used in rubbish autohemagglutination pyrolysis technique field.Meanwhile, the utility model Have the beneficial effect that：

1. the utility model is pyrolyzed the subsection setup of chamber, is conducive in different phase with different temperature combustions, makes organic Thing can eliminate the material conditions of bioxin generation by thorough combustion oxidation.

2. the setting of the utility model purification separation device, is conducive to carrying out purification separation filtering to flue gas, more preferably environmentally friendly.

3. the setting of the utility model cogeneration unit, is conducive to being generated electricity using the flue gas that burning is produced, realized Twice laid, turn waste into wealth, economic well-being of workers and staff can be achieved.
