Abstract
The invention provides a boiler dust removal circular processing system. The boiler dust removal circular processing system comprises a main dust remover, an auxiliary dust remover, a reaction tank, a sedimentation tank, a pump chamber water collecting tank and a water cut-off safety protection device. The water cut-off safety protection device is used for independently starting any main circulating water pump and/or auxiliary circulating water pump. The boiler dust removal circular processing system has the following advantages that the water cut-off safety protection device enables any one in all the circulating water pumps to be independently started; two or more circulating water pumps can also be started simultaneously; the operation of the entire set of system is not limited by the water cut-off safety protection device; when the circulating water pumps break down or cannot operate or operate idly or stop due to breakdowns, an electromagnetic valve is started, water is supplied to the boiler dust removers, a sound-light alarm is given out to remind an operator of the breakdown of equipment, and standby water is controlled; when the circulating water pumps operate idly or stop due to the breakdowns, the standby water is automatically supplied, so that the demand for boiler dust removal water is met, and the safe and economical operation of a boiler is protected.
