Background technology

Oxygen content is lower in the air of high altitude localities, and during as 3800 meters of height above sea levels, its air oxygen content has only about 60% of low altitude area air oxygen content.Therefore, the refuse pyrolysis incineration technology is very different in high altitude localities and low altitude area.At present, there are problems such as waste incineration is insufficient, auxiliary fuel consumption is big, operation cost height in the refuse pyrolysis CIU of domestic middle-size and small-size high altitude localities.

The utility model content

The utility model is made improvement at the problem that above-mentioned prior art exists, be that the technical problems to be solved in the utility model provides a kind of New-type refuse vehicle pyrolytic incineration equipment that burns at the high altitude localities refuse pyrolysis, this New-type refuse vehicle pyrolytic incineration equipment can improve high altitude localities waste incineration effect, saving auxiliary fuel effectively and cut operating costs.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of New-type refuse vehicle pyrolytic incineration equipment, comprise pyrolysis oven, secondary combustion chamber and dump chimney, described pyrolysis oven enters secondary combustion chamber to the fuel gas that rubbish carries out the pyrolysis generation, described secondary combustion chamber enters in the dump chimney from advancing mouth the fuel gas high-temperature gas that forms that fully burns, be provided with in the described dump chimney for the heat exchanger that improves the normal temperature combustion air temperature, the air outlet of described heat exchanger is connected to pyrolysis oven and secondary combustion chamber respectively through the secondary hot-air duct.

Further, the air inlet of described heat exchanger is connected to air blast by the secondary cold-air duct.

Further, the outlet flue of described dump chimney is connected to flue gas purification system by pipeline.

Compared with prior art, the utlity model has following beneficial effect: this New-type refuse vehicle pyrolytic incineration equipment arranges a heat exchanger dexterously in the dump chimney, utilize the high-temperature flue gas in the secondary combustion chamber to heat combustion air as thermal source, combustion air after will heating by the secondary hot-air duct is sent into pyrolysis oven and secondary combustion chamber, guarantee rubbish effectively pyrolysis and fully burning in secondary combustion chamber of flammable pyrolysis smoke in pyrolysis, have simple and reasonable, effectively improve high altitude localities waste incineration effect, save auxiliary fuel, advantage such as cut operating costs.

The utility model is described in more detail below in conjunction with the drawings and specific embodiments.

Among the figure: 1-pyrolysis oven, 2-secondary combustion chamber, 3-secondary hot-air duct, 4-dump chimney, 5-secondary cold-air duct.

The specific embodiment

Shown in Fig. 1 ~ 4, a kind of New-type refuse vehicle pyrolytic incineration equipment, comprise the pyrolysis oven 1 that is connected in series successively, secondary combustion chamber 2 and dump chimney 4, the fuel gas that 1 pair of rubbish of described pyrolysis oven carries out the pyrolysis generation enters secondary combustion chamber 2,2 pairs of fuel gas of described secondary combustion chamber high-temperature gas that forms that fully burns enters in the dump chimney 4 from advancing mouth, be provided with in the described dump chimney 4 for the heat exchanger that improves the normal temperature combustion air temperature, the air outlet of described heat exchanger is connected to pyrolysis oven 1 and secondary combustion chamber 2 respectively through secondary hot-air duct 3, the air inlet of described heat exchanger is connected to air blast by secondary cold-air duct 5, and the outlet flue of described dump chimney 4 is connected to flue gas purification system by pipeline.

In the present embodiment, rubbish carries out pyrolysis in pyrolysis oven 1, and carbon residue burns the generation heat and makes rubbish pyrolysis at a certain temperature behind the employing refuse pyrolysis, therefore must provide about 30% of burning oxygen requirement to carry out carbon residue and burn the supply heat.The high altitude localities is because air pressure is low, oxygen content is less relatively in the air, the unit volume oxygen content is less in pyrolysis oven 1 burning zone, effectively burn for reaching carbon residue, just higher temperature must be arranged, effective way is that combustion air carries out preheating for this reason, brings more heat transfer into to enter in the pyrolysis oven 1, improves pyrolysis oven 1 burning zone temperature.

In the present embodiment, but the burning fume of refuse pyrolysis fully burns in secondary combustion chamber 2, for flue gas is burned thoroughly, more fuel gas, sufficient combustion-supporting oxygen, well turbulivity, higher incineration temperature and certain gas residence time must be arranged.Because high altitude localities air pressure is low, the contained combustible of unit volume is less relatively in the flue gas, institute's oxygen content is also less relatively in the combustion air simultaneously, therefore under higher temperature, fully burn in secondary combustion chamber 2 for reaching flue gas, effective way is that combustion air carries out preheating, bring more heat transfer into and enter in the secondary combustion chamber 2, improve secondary combustion chamber 2 temperature.

In the refuse pyrolysis CIU, the safe handling for the protection flue gas purification system generally is provided with dump chimney 4 behind secondary combustion chamber 2.Waste incineration relevant criterion according to country, the flue-gas temperature that secondary combustion chamber 2 is discharged is greater than 850 ℃, this New-type refuse vehicle pyrolytic incineration equipment arranges a heat exchanger dexterously in dump chimney 4, utilize the high-temperature flue gas in the secondary combustion chamber 2 to heat combustion air as thermal source, (as 250 ℃) entered pyrolysis oven 1 and secondary combustion chamber 2 by pipeline after combustion air was heated to higher temperature, guaranteed rubbish effectively pyrolysis and fully burning in secondary combustion chamber 2 of flammable pyrolysis smoke in pyrolysis.

In the present embodiment, rubbish carries out pyrolysis at pyrolysis oven 1 and produces fuel gas, fuel gas enters secondary combustion chamber 2 and fully burns formation temperature greater than 850 ℃ of high-temperature flue gas, high-temperature flue gas enters the dump chimney 4 inner flues with heat exchanger again, through turbulent flow, hear rate high-temperature flue-gas are down to below 600 ℃ and are entered in the flue gas purification system after a while.Be energy efficient, rubbish, the more abundant burning of combustible gas physical efficiency, air blast blasts the normal temperature combustion air to secondary cold-air duct 5, the normal temperature combustion air enter in the dump chimney 4 inner air channels with heat exchanger with flue in high-temperature flue gas finish indirect heat exchange, normal temperature combustion air temperature behind the indirect heat exchange is increased to more than 250 ℃, and last combustion air enters pyrolysis oven 1 respectively and secondary combustion chamber 2 carries out combustion-supporting through secondary hot-air duct 3 again.

The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
