Abstract
The utility model discloses a thermal power plant deslagging system with communicating pipes. The deslagging system comprises a plurality of cold ash hoppers, wherein a water-seal inserting plate is arranged below each cold ash hopper; the upper edge of each water-seal inserting plate is in hermetic connection with the lower edge of an outlet of the corresponding cold ash hopper; a spiral slag salvaging machine groove body is arranged below each water-seal inserting plate; the water-seal inserting plates are inserted into the spiral slag salvaging machine groove bodies; the lower end of each water-seal inserting plate is lower than an overflow port of the corresponding spiral slag salvaging machine groove body; and the communicating pipe is arranged between the every two spiral slag salvaging machine groove bodies. The deslagging system has the advantages that the communication pipes are arranged among the spiral slag salvaging machine groove bodies to ensure the leakproofness of a hearth, so that the normal combustion of the hearth is ensured; and isolation inserting plates are arranged among the communicating pipes, so that when a single spiral slag salvaging machine is overhauled, communication among the spiral slag salvaging machine groove bodies can be partitioned by using the isolation inserting plates, and the single spiral slag salvaging machine is convenient to overhaul.
Description
Technical field
The utility model relates to a kind of slag removal system of thermal power plant, particularly relates to a kind of slag removal system of thermal power plant with communicating pipe.
Background technology
The screw cinder cleaner group is the slag remover for boilers of a kind of high-efficiency and continuous in the slag removal system of thermal power plant.Lime-ash in the burner hearth falls into by furnace hopper in the screw cinder cleaner cell body of the completely flame-out water of storage, after poly-cold water is quenched, makes the abundant granulation of clinker, is pulled out through submerged slag conveyor by screw cinder cleaner and enters the slag storehouse.On the boiler lower collecting box pipe water seal plate is installed, and corresponding the insertion in the screw cinder cleaner cell body, the water seal plate inserts in the screw cinder cleaner cell body, makes boiler continuous discharging slag operation under complete water seal state.Guarantee the seal of burner hearth, the thermal efficiency of boiler is had important impact.
Utilize the continuously water filling in the screw cinder cleaner cell body of pulp water circulating pump, after liquid level reached the overfall extreme higher position in the screw cinder cleaner cell body, overflow recycled in buffer tank follows square auger dragveyer cell body to the submerged slag conveyor cell body.Screw cinder cleaner filling pipe in use for some time fouling is frequent, causes the interior liquid level of indivedual screw cinder cleaner cell bodies to be lower than water seal plate lower limb, causes the screw cinder cleaner furnace hopper to leak out, and has a strong impact on the normal combustion of burner hearth.
The utility model content
The purpose of this utility model is to provide a kind of slag removal system of thermal power plant with communicating pipe.
The purpose of this utility model is implemented by following technical scheme, a kind of slag removal system of thermal power plant with communicating pipe, it comprises some furnace hoppers, each described furnace hopper below is equipped with the water seal plate, the lower limb of the top edge of described water seal plate and the outlet of described furnace hopper is tightly connected, the below of each described water seal plate is equipped with the screw cinder cleaner cell body, described water seal plate inserts in the described screw cinder cleaner cell body, the lower limb of described water seal plate is lower than the overfall on the described screw cinder cleaner cell body, be provided with communicating pipe between two described screw cinder cleaner cell bodies, the two ends of described communicating pipe are communicated with two described screw cinder cleaner cell bodies respectively, and the lower limb of described communicating pipe is higher than the lower limb of described water seal plate, the top edge of described communicating pipe is higher than the minimum point of described overfall, so that the pulp water in the screw cinder cleaner cell body can guarantee the sealing of burner hearth, want simultaneously to prevent that the pulp water in certain the screw cinder cleaner cell body from flowing in the submerged slag conveyor cell body through overfall first so that pulp water at first will keep water level consistent each screw cinder cleaner cell body liquid level through communicating pipe.
Described communicating pipe is semicircle flute profile pipeline, the convenient water level of observing, and the top edge of described communicating pipe is higher than the minimum point of described overfall, prevents from causing pulp water by the top overflow of described communicating pipe because water level is too high.
The inwall of described communicating pipe is provided with the isolation slot along semi-circumference, and it also includes the isolation plate that matches with described isolation slot, and when the separate unit screw cinder cleaner overhauled, available isolation plate cut off between the screw cinder cleaner cell body and is communicated with easy access.
The inwall of described communicating pipe is provided with a wash rice water integrated circuit board groove at least along semi-circumference, and each described wash rice water integrated circuit board groove all has a wash rice water plate that matches with it.
The inwall of described communicating pipe is provided with two wash rice water integrated circuit board grooves along semi-circumference, and two described wash rice water integrated circuit board grooves are located at respectively the two ends of described communicating pipe.
The utility model has the advantage of, by between the screw cinder cleaner cell body, installing communicating pipe additional, guaranteed the seal of burner hearth, and then guarantee the normal combustion of burner hearth; Establish the isolation plate between communicating pipe, when the separate unit screw cinder cleaner overhauled, available isolation plate cut off between the screw cinder cleaner cell body and is communicated with easy access.
