Description
Affiliated technical field
The utility model belongs to the field of environment protection of refuse treatment, particularly relates in a kind of garbage microwave pyrolysis treating processes, and the cracking vapour of generation is used to prepare the decoking dust removal installation of fuel vapor.
Background technology
Rubbish cracked definition: be meant and supply with the process that the certain energy of rubbish makes the organism generation scission reaction in the rubbish under certain condition.Can be expressed as:
Organic waste → gas (H
2, C
xH
y, CO, CO
2, NH
3, H
2S, HCl, H
2O etc.)+organic liquid (tar, aromatic hydrocarbons, kerosene, organic acid, alcohol, aldehydes etc.)+carbon black, lime-ash
By above-mentioned definition as can be seen rubbish cracked cracking vapour be the primary product of its reaction, the level of utilizing of rubbish cracking vapour directly influences the success or failure that cracking technology is implemented.
The cracking vapour thermal value range that conventional rubbish cracking process is produced is at 3000-4000kcal/Nm
3, its main component is based on carbonic acid gas, carbon monoxide, methane, ethene etc., because its calorific value is lower, usually as the Industrial Stoves fuel combustion or get back to cracking system burning back as one of power supply means of system.
Rubbish cracking under microwave heating condition is handled, and can make full use of microwave at the thermal effect and the non-thermal effect that promote reaction process.Change reaction Kinetics Model, generate the split product that is different from conventional process.
Garbage microwave pyrolysis is handled the composition characteristic of gaseous product: CO in low-temperature reduction atmosphere
2, NOx, SO
2Generation is extremely low, because quick heating, the gas peculiar smell is lower, does not almost have the pitch flavor.The calorific value of garbage microwave pyrolysis vapour was on average at 6800-7600kcal/Nm when the gaseous constituent of garbage microwave pyrolysis product was mainly 500 ℃ of inflammable gass such as carbon monoxide, methane, ethane, ethene, acetylene, propane and cracking temperatures such as small amount of nitrogen, carbonic acid gas
3
Its calorific value of cracking vapour that garbage microwave pyrolysis produced has in sum reached civilian 10T heating value of natural gas standard, and its application performance obviously is better than common rubbish cracking vapour.
But the cracking vapour of garbage microwave pyrolysis, after cracking is finished be with tar, moisture, and some sour gas mix and separate out.Can not directly use and to use after taking certain control techniques to purify.
The rubbish splitting gas main core technology for preparing fuel vapor is in sum: 1) tar and moisture removal technology, 2 efficiently) the efficient removal technology of sour gas.
The coal tar of conventional coke-oven plant is collected and is adopted the coal oven dithio-gas to spray with cyclic ammonia water and primary cooler condensation cooling is reclaimed, so contains a large amount of water. and must be through clarifying between recovery vehicle and after heating leaves standstill dehydration, being sent to the tar job shop and processing.
Be different from coal tar fully because garbage microwave pyrolysis is handled the output and the character of the tar that produces, be mainly reflected in:
The output of 1) refuse treatment process coal tar is about about raw refuse weight 3-4%, so the oil offtake of garbage microwave pyrolysis device every day is well below the coke-oven plant of routine.
2) chemistry of garbage microwave pyrolysis tar and physical properties are far different than coal tar.Coal tar is mainly to be made up of polycyclc aromatic compound, and alkylaromatic hydrocarbon content is less, and high boiling component is more, Heat stability is good.Rubbish cracked tar mainly contains saturated or unsaturated hydro carbons material and a part of aromatic hydrocarbon substance.Domestic waste is because the characteristic in its source has determined its pyrolytic tar must contain more oxygen-containing functional group.The viscosity of garbage microwave pyrolysis tar, softening temperature etc. are different from coal tar fully.
To sum up the decoking technique of garbage microwave pyrolysis gas is not suitable for adopting routine, coking tail gas decoking technique.
The removal of sour gas, the deacidifying process of garbage microwave pyrolysis cracking vapour can be used for reference conventional selexol process, the process implementing of depickling.
The applicant handles garbage microwave pyrolysis and carries out big quantity research; processing to the cracking vapour of garbage microwave pyrolysis in the prior art also is in blank; be fully utilized for making garbage microwave pyrolysis handle cracking vapour; reduce discharging; improve energy recovery; the protection environment, the processing of research and development cracking vapour is the technical problem that needs to be resolved hurrily.
