Abstract
The utility model relates to an external gypsum slurry filter of a desulfurization absorbing tower, which comprises a barrel body, a barrel cover and a filter mesh; the barrel body is provided with a slurry inlet pipe and a slurry outlet pipe; the inside of the barrel body is divided into an upper chamber and a lower chamber by a partition board; the filter mesh is fixed on the partition board; the upper chamber is communicated with the slurry inlet pipe; the lower chamber is communicated with the slurry outlet pipe; and the lower chamber is provided with a slurry discharge pipe. The filter is arranged outside the absorbing tower, and is conveniently connected between the valve outlet of the gypsum slurry discharge pipe of the absorbing tower and a gypsum slurry pump through a flange; the filter mesh can be taken out, the cleaning is convenient, the monitoring and repair are convenient during the operation, so as to ensure the normal operation of the equipment.
Description
Technical field
The utility model relates to a kind of desulfuration absorbing tower external gypsum slurries filter, is used for smoke-gas wet desulfurization, and the gypsum slurries that the absorption tower is discharged carries out filtering and impurity removing.
Background technology
At present, absorption tower gypsum slurries excavationg pump inlet filter is installed in the absorption tower in domestic most of wet flue gas desulfurizer, promptly is arranged on the absorption tower slurries and goes out before the tower.So no doubt saved the place, be beneficial to pipe arrangement, but filter integral body is immersed in the gypsum slurries in the tower, all parts (comprising securing member) must be anticorrosion materials, and investment cost is bigger.In long-time running, because the impulsive force and the vibration of slurries, between each parts of filter and the junction between filter body and the absorption tower takes place loosening easily even damages, and the maintainer is difficult to observe the running status of filter, is difficult in time finding and handling problems.The bolt and nut part of filter may come off and enter in pipeline, pump and the upstream device, influences the safe operation of equipment and system, brings hidden danger for the safe and stable operation of system.
Summary of the invention
The utility model purpose provides a kind of desulfuration absorbing tower external gypsum slurries filter, and easy access and maintenance are avoided causing a hidden trouble to the safe and stable operation of desulphurization system.
The utility model gypsum slurries filter comprises cylindrical shell, cover and filter screen, cylindrical shell is provided with slurry inlet and takes over and the slurries discharge connection, be divided into upward chamber and following chamber with dividing plate in the cylindrical shell, filter screen is fixed on the dividing plate, last chamber is taken over slurry inlet and is communicated, following chamber communicates with the slurries discharge connection, and the following chamber of cylindrical shell is provided with discharge pipe.
The cylindrical shell upper fixed has bracing frame and is used to compress the lifting screw of cover, and this lifting screw is threaded with bracing frame, and the lower end compresses cover.
Said bracing frame is formed by connecting by bracer and crossbeam, and lifting screw is installed on the crossbeam.
Be provided with the O RunddichtringO between said cover and cylindrical shell are suitable for reading.
Said cover centre is equipped with bearing and is paid.
Said lifting screw is equipped with handle.
Said filter screen is the cup type net that stretches into chamber under the cylindrical shell.
The chamber sidewall is provided with peep hole under the said cylindrical shell, and peep hole is provided with plug.
Said slurry inlet is taken over and the slurries discharge connection is equipped with adpting flange.
This external filter places outside the absorption tower, is connected in easily between absorption tower gypsum slurries dump valve and the slush pump by flange.Open cover, filter screen can take out, the convenient cleaning.In service being convenient to monitored and overhauled, and guarantees the normal operation of equipment.
Description of drawings
Fig. 1 is this external gypsum slurries structure of filter schematic diagram.
1-cylindrical shell, 2-crossbeam, 3-discharge pipe, 4-filter screen, 5-peep hole plug, 6-cover, 7-bearing is paid, 7-1-bearing cap, 8-lifting screw, 8-1-handle, 9-cover seat ring, 10-dividing plate, 11-bolt, 12,13-bracer, 14-O RunddichtringO, 15-slurry inlet is taken over, 15-1-suction flange, 16-slurries discharge connection, 16-1-outlet(discharge) flange, 17-pin.
The specific embodiment
As Fig. 1, be divided into upward chamber and following chamber with dividing plate 10 in the cylindrical shell 1, suitable for reading being fixed on the dividing plate 10 of cup type filter screen 4, last chamber is taken over 15 with slurry inlet and is communicated, and is provided with suction flange 15-1; Following chamber communicates with slurries discharge connection 16, is provided with outlet(discharge) flange 16-1; The bottom, following chamber of cylindrical shell 1 is provided with discharge pipe 3, and following chamber sidewall is provided with peep hole and plug 5.The cover seat ring 9 and the cover 6 of being provided with suitable for reading of cylindrical shell 1 is provided with O RunddichtringO 14 therebetween.Bracer 12,13 and crossbeam 2 are formed bracing frame, and bracer 12,13 is fixed by welding in the left and right sides of cylindrical shell, and crossbeam 2 usefulness bolts 11 are connected on bracer 12 and 13.Lifting screw 8 is threaded with crossbeam 2, and its lower end is tight against at cover 6, and the centre of cover 6 is provided with bearing and pays 7, screws the capping 7-1 that bearing is paid with pin 17.
This filter places outside the absorption tower, promptly between the valve outlet port and gypsum slurries pump inlet of the outer slurries discharge pipe of tower, connects by between flange 15-1,16-1 and the corresponding pipeline.But setting pressure table on the connecting pipe at this filter two ends reacts the blockage of filter screen by the two ends differential pressure value, if differential pressure surpasses setting value, shows that promptly the filter screen stopping state is comparatively serious, needs cleaning.Switch to the bypass operation during cleaning earlier, turn handle 8-1 opens top cover 6 subsequently, takes out filter screen 4 and clears up; The peep hole Butterworth Hatch of holding concurrently, detachable lower end cap 5, water flowing is washed filter interior; Open bottom discharge pipe 3 simultaneously, slurries or flushing water in the emptying tube.
