Pyrolysis system+filter subsystem+oil recycles subsystem, increases filter subsystem compared to embodiment 2, reason exists
Contain a large amount of dust in the pyrolysis gas that partial waste is generated by pyrolysis, if the pyrolysis gas containing a large amount of dust is direct
Carry out oily condensing recovery then may after oil in may also contain a large amount of dust, the equipment for having pyrolysis gas to pass through and pipeline are all
A large amount of dust may be accumulated, the failure and security risk of the blocking of pipeline are caused.It is therefore desirable to increase this kind of application
The pyrolysis gas outlet of pyrolysis oven is increased a pipeline to filter by filter operation, and increase filter subsystem, filter
Outlet connect the first oil condenser 12 top ejection port, filtered pyrolysis gas from this head into port into first oil it is cold
Condenser 12.The system is more flexible, and different accesses is selected according to the characteristics of pyrolysis gas, if containing a large amount of powder in pyrolysis gas
Dirt then opens the electric control valve between filter, pyrolysis gas is first input into filter and is dusted operation, then by dedusting
Pyrolysis apparatus afterwards is input to the first oil condenser and starts oil recovery operations；When in pyrolysis gas do not contain dust when, then between open
With the electric control valve between the first oil condenser 12, pyrolysis gas is directly inputted to the first oil condenser and starts oil recovery operations.
Due to containing a large amount of tar, tar especially therein, when system just brings into operation, in filter in pyrolysis gas
Membrane tube temperature it is lower, when pyrolysis gas just starts to be input to membrane tube, the tar in pyrolysis gas is easy to entering in membrane tube to the cold
The problem of being condensed at mouthful, therefore being easy to happen tar blocking membrane tube.In order to solve this problem, also add one from combustion chamber to
The connecting pipe of filter inlet, the pipeline are equipped with electric control valve.When system is just started to work, pyrolysis gas and mistake are first closed
Electric control valve between filter opens pyrolysis gas and the electric control valve between the first oil condenser 12, and pyrolysis gas is directly defeated
Enter to the first oil condenser first directly start oil recovery operations, while open combustion chamber to filter inlet connecting pipe electricity
Valve is controlled, high-temperature flue gas is first input into filter, high-temperature flue gas is allowed to preheat the filter chamber and membrane tube of filter, when
When preheating reaches predetermined temperature, the electric control valve of the connecting pipe of closing combustion chamber to filter inlet closes pyrolysis
Gas and the electric control valve between the first oil condenser 12, while the electric control valve between pyrolysis gas and filter is opened, it will be hot
It vents one's spleen to be first input into filter and is dusted operation, then the pyrolysis apparatus after dedusting is input to the first oil condenser and starts oil time
It brings drill to an end work.The problem of can solve tar blocking membrane tube in this way.
Solving the problems, such as tar blocking membrane tube, there are also a kind of schemes, and using nested type filter, nested type filter includes 2
A or 2 or more filter cavities, two filter cavities work independently, between pass through Heat Conduction Material separation.Specific to the application,
Can only filter cavity is equipped with membrane tube wherein, the high temperature pyrolysis gas filtered will be needed to be connected to this equipped with membrane tube
On channel, high-temperature flue gas is connected on the channel for being equipped with setting membrane tube.When system brings into operation, first opens and be equipped with setting membrane tube
Channel on electric control valve, allow high-temperature flue gas to be introduced into and passed through air filtration, high-temperature flue gas is led by two filter cavities
Hot material heats the filter cavity for being equipped with membrane tube, while also heating to membrane tube itself, when the temperature of membrane tube reaches
When pre-set value, the electric control valve being then turned on this channel equipped with membrane tube, high temperature pyrolysis gas just initially enter filtering
Device is filtered operation, since the membrane tube in filter had been warmed up, greatly reduces and asking for tar condensation occurs
The probability of topic.
