Detachable full-automatic coke oven crude gas combustion unit having pretreating function

The utility model relates to a separating-style full-automatic cokery crude gas burner-unit with a pre-treating function. The utility model comprises a crude gas heater 14, a crude gas filter 21, a valve-group 35, a burner 57, a unit-fan 60, an emitting-test device, a crude gas general feeding-pipe 19, a semi-crude gas general feeding-pipe 41, an emitting-test branch-pipe 45, an igniting gas branch-pipe 61 and a compressed air general pipe 65. The crude gas general feeding-pipe 19 is connected into the lower part of the crude gas heater. After two crude gas filters are connected with the crude gas general feeding-pipe in a parallel sequence, the semi-crude gas general feeding-pipe is connected into the crude gas general feeding-pipe. The semi-crude gas general feeding-pipe is connected into the main gas-inlet of the burner. The unit has the pre-treating functions such as cokery crude heating and filtering, etc. which can make the cokery crude gas through the unit reach the ideal burning effect with a perfect performance of chemical potential. The utility model explores a wide perspective for a thorough utilization of the cokery crude gas and solves the problem that the cokery crude gas cannot be burnt directly.
