Abstract
The invention provides an apparatus for realizing use of reclaimed water as device seal water after sand filtration. The apparatus for realizing use of reclaimed water as device seal water after sand filtration comprises a reclaimed water lifting system, a sand filter, an air compressing system and a reclaimed water transfer system. The reclaimed water lifting system is connected with a sewage plant reclaimed water pipeline to make the reclaimed water in the sewage plant enter the sand filter and be treated; the sand filter is filled with filter sands, and the reclaimed water entering the sand filter are filtered by the filter sands to remove suspensions in water; the air compressing system contains an air compressor and an air storage tank, and compressed air is introduced to the sand filter to blow a water and sand mixture in order to ensure automatic cleaning of the filter sands in the sand filter; and the reclaimed water transfer system contains a water storage tank and a reclaimed water transfer pump to make the sand-filtered reclaimed water be transferred to a seal water system and be used. The reclaimed water substitutes clear water to be used as the device seal water after the sand filtration, so the water resource consumption is saved, and the production cost is reduced.
Description
Technical field
The present invention relates to the technical field of novel papermaking, more particularly to a kind of middle Water Sproading reutilization technology.
Background technology
In general sealing water be used at packing or the mechanical seal of equipment (pump, pressurized screen, agitator etc.), plays sealing and cooling effect, equipment sealing water generally uses the fresh water after water process, that is, so-called clear water.Clear water price is high, and production cost is very big.
In the productive life of city, produce middle water in a large number.Middle water, be water quality in tap water and blow-off line between sewage, be to be up to state standards after purified process, the undrinkable water that can use within the specific limits.
Middle water is cheap, but in middle water or contains a large amount of impurity it is impossible to directly be used as sealing water.
Content of the invention
In order to solve the above problems, the present invention devises a kind of device of water in processing, and it can utilize middle Water Sproading more for impurity, be used as the sealing water of equipment, both can ensure that the normal operation of equipment, and reduced production cost, saving water resource again after process.
It is an object of the invention to provide being used as, after a kind of middle water sand filter, the device that equipment seals water, it is achieved through the following technical solutions：It is used as, after a kind of middle water sand filter, the device that equipment seals water, including：Middle water lifting device, sand filter, compressed air system, middle tank, middle water transfer device.
Between described sand filter and middle water lifting device, connected by intermediate water pipeline,
Described sand filter bottom is also associated with blow-off line；
Described sand filter, filtrate adopts natural siliceous sand, particle diameter 0.6-1.2mm；
Described middle water transfer device is middle water shifting pump；
Described compressed air system, including air accumulator and air compressor；
Compressed air >=the 0.4mpa of described air compressor.
Beneficial effects of the present invention are：It is used as, using after the middle water sand filter that technical scheme makes, the device that equipment seals water, the float of sewage disposal middle section water can be reduced, make middle water can be used as the sealing water of equipment, reduce production cost, saving water resource.
Brief description
Fig. 1 is the structural representation of this device.
Wherein：1- intermediate water pipeline, 2- blow-off line, water shifting pump in 3-, the flow direction median (flowing to seal water system) after 4- process, water lifting device in 5-.
Specific embodiment
Below according to accompanying drawing, the present invention is described in further detail.
As illustrated, being used as, after a kind of middle water sand filter, the device that equipment seals water, including：Middle water lifting device 5, sand filter, compressed air system, middle tank, middle water transfer device.
Between described sand filter and middle water lifting device 5, connected by intermediate water pipeline 1,
Described sand filter bottom is also associated with blow-off line 2；
Described sand filter, filter sand adopts natural siliceous sand, particle diameter 0.6-1.2mm；
Described compressed air system, including air accumulator and air compressor；
Compressed air >=the 0.4mpa of described air compressor；
The middle water of Sewage Plant, by middle water lifting device, through intermediate water pipeline, enters sand filter,
Built with filter sand, middle water flows in sand filter sand filter from lower to upper, is filtered by filter sand, goes the float in eliminating water；
Sand filter bottom is passed through compressed air, by the castering action of compressed air, filter sand is carried out.
Compressed air is derived from air accumulator, is persistently supplied by air compressor.
Process through sand filter, middle aqueous suspension ss≤50mg/L drops to ss≤20mg/L, meet the use standard of sealing water.Middle water after process, is stored in middle tank.Middle water after process, water shifting pump in warp, flow to seal water system.
Make middle water that clear water can be replaced to be used as sealing water, reduce clear water consumption, saved production cost；It is also the secondary utilization of centering water, enable resource cycling and reutilization.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under the enlightenment of the present invention; however, making any change in its shape or structure, every have technical scheme identical or similar to the present application, is within the scope of the present invention.
