Further, still install the endoscope on the delivery pipeline, in order to observe tail gas through the endoscope.
Further, install access hole and air pressure governing valve on the seal pot, overhaul in order to be convenient for through the access hole, through the air pressure governing valve, can in time adjust atmospheric pressure, let tail gas carry smoothly, avoid appearing the condition emergence that tail gas leaked.
Furthermore, the gas water seal tank overflow port valve is arranged on the conveying pipeline, and the device can be closed through the gas water seal tank overflow port valve.
Further, a delivery pipe control valve is installed on the delivery pipe, and condensate can be prevented from flowing back when the device is stopped.
Further, the conveying pipeline, the output pipeline and the sealing tank are connected by flanges, so that the conveying pipeline, the output pipeline and the sealing tank are convenient to install, detach and replace.
From the above technical scheme, the utility model has the following advantages:
The utility model provides a gas water seal groove overflows tail gas closing device, the device overall structure is simple, can be effectively to gas water seal groove gas condensate overflow mouth loss have inflammable and explosive, poisonous and harmful, the tail gas that endangers such as choking is retrieved, under the unblocked prerequisite of guaranteeing the condensate emission, simultaneously, can guarantee the personal safety of post staff to and improve surrounding operation environment, have obvious environmental protection, security benefit.
