Abstract
The utility model discloses an impurity filter for ash-sediment content water. The filter comprises a filter cylinder, a cylinder flange connected with the filter cylinder, a fixing groove arranged in the filter cylinder and a movable filter screen positioned in the fixing groove. The impurity filter for ash-sediment content water is integrally mounted on an outlet pipe of an ash pump with the upper portion connected with a water inlet pipe and the lower portion connected with a water outlet pipe, the cylinder flange can be freely detached to conveniently pump or install the movable filter screen. After the filter is disposed on the outlet pipe of the ash pump, the movable filter screen can be regularly detached to clean according to requirements to prevent various spray nozzles from clogging when ash-sediment content water is treated and reused, and long-term safe operation of related facilities can be guaranteed.
Description
Technical field
The utility model relates to the lime-ash water treatment facilities that a kind of thermal power plant lime-ash water system adopts, especially a kind of grey pulp water contaminant filter.
Background technology
To discharge a large amount of lime-ash during the boiler operatiopn in thermal power plant, generation current factory adopts the Wet ash Transportation ash-slag delivery more, its main technique flow process is: the lime-ash that boiler is discharged enters grey slag runner, in the ash slag runner lotic water nozzle is housed all at a certain distance, lime-ash in the slag runner is dashed to clear ashpit under the effect of torrent nozzle, crossing filter cake through three grades of clear ashpits is clear water, squeeze into torrent nozzle water supply line by ash pump again, for torrent nozzle water, make the water in the clear ashpit obtain recycling.The defective of this system is: because the water in the clear ashpit has only passed through simple precipitation process, also there are impurity such as a certain amount of slag, ash particle in the water, after the pump long-time running, can cause the obstruction of equipment such as system pipeline, valve, flushing cinder nozzle, influence the long period safe operation of system equipment.
Summary of the invention
The utility model is in order to solve the defective that the lime-ash water treatment of existing power plant exists, a kind of novel grey pulp water contaminant filter is provided, can filter out impurity such as clinker in the grey pulp water, ash particle, all kinds of nozzles stop up when preventing to recycle after the lime-ash water treatment, guarantee the safe operation of relevant device.
The utility model has adopted following technical scheme:
Ash pulp water contaminant filter comprises the connected shell flange of filter cylinder, and the sliding screen of placing in holddown groove of establishing in the filter cartridge and the holddown groove.
The integral installation of ash pulp water contaminant filter on the ash pump outlet conduit, on tap into waterpipe, following pass-out waterpipe.Filter cartridge and shell flange are made flexible connection, and shell flange can arbitrarily be dismantled, so that extract or install sliding screen.After the ash pump outlet conduit is installed this filter, can optionally regularly pull down sliding screen and clear up, to prevent having impurity in the water.
This ash pulp water contaminant filter can filter out impurity such as clinker in the grey pulp water and ash particle, and all kinds of nozzles stop up when preventing to recycle after the lime-ash water treatment, can guarantee the long period safe operation of relevant device.
Description of drawings
Accompanying drawing is the structural representation of grey pulp water contaminant filter
The specific embodiment
Introduce embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in the figure, grey pulp water contaminant filter mainly is made up of filter cartridge 5, shell flange 2, holddown groove 3 and sliding screen 4.The integral installation of ash pulp water contaminant filter on the ash pump outlet conduit, on tap into waterpipe 1, following pass-out waterpipe 6.Filter cartridge 5 can be made a rectangular box, place sliding screen 4 within it on the cross section position, fix by the holddown groove of making by angle bar up and down 3, the top movable of casing connects a square cylinder flange 2, shell flange 2 can arbitrarily be dismantled, so that extract or installation sliding screen 4, sliding screen 4 can regularly be pulled down and clear up, and prevents to filter in the water of back to have impurity such as clinker and ash particle.
