Abstract
The invention relates to a single-pump positive-pressure running self-pressing back-washing fluid processing device. The device comprises a fluid inlet control valve, a running pump, a fluid outlet pipeline, a fluid processing device cavity and a sludge-discharging valve, and is characterized in that the positive-pressure running is carried out in the fluid processing device cavity during a running process; the positive-pressure running is carried out in the fluid processing device cavity when back-washing is performed by the device; a fluid in a circulating system is used as a back-washing fluid; and a magnitude of the pressure of the back-washing fluid is determined by the pressure of the fluid in the circulating system and no pump is used for pressurizing. A novel structure of a water processing device is adopted in the single-pump positive-pressure running self-pressing back-washing fluid processing device, so that a single-pump water processing device is characterized by simpleness in manufacture, low cost and simpleness and convenience in operation. Especially, by using the fluid in the circulating system as the back-washing fluid, the problem that a new back-washing pipeline is difficult to be added because no by-pass water processing scheme is taken into account in an old system is solved in modifying projects of a central air-conditioning circulating water system and an industrial circulating water system.

Background technology
In the industrial circulating water fluid treating plant, the by-pass flow fluid treating plant of all single pump band back-purge systems does not all have single pump operation under positive pressure from the design of pressing recoil in modern times, and present single pump side stream treatment facility recoil all is to pressurize through water pump; Recoil structure is complicated; If in the industrial cycle water system, adopt intrasystem water without water pump pressurization recoil, its structure is just simpler, the manufacturing of slave unit; Expense is cheaper on the installation cost, and staff's operation is easier.
Summary of the invention
Goal of the invention:
The present invention provides a kind of single pump operation under positive pressure from pressure recoil fluid treating plant, and inventing this equipment mainly is because can reduce a recoil of laying fluidic pipeline fee usefulness, and it is simple to possess manufacturing simultaneously, convenience operation.
Technical scheme
Like Fig. 1, make a single pump negative pressure operation from pressing the recoil fluid treating plant to form by four major parts:
1. fluid moves inlet part=fluid intake pipeline A+ fluid intake valve A
1+ fluid intake pipeline A
2+ process pump A
3+ fluid intake pipeline A
4(fluid intake pipeline A wherein the pending chamber of a termination fluid treating plant cavity W on)
2. the fluid operation outlet part=fluid recoil part=fluid outlet pipeline C (fluid outlet pipeline C wherein a termination fluid treating plant cavity W treatment chamber) that enters the mouth
3. blowdown exports part=blow-off line B+ blowdown valve B
1+ blow-off line B
2(blow-off line B is the pending chamber of a termination fluid treating plant cavity W wherein)
4. the pending chamber of fluid treating plant cavity W=fluid treating plant cavity W+fluid treating plant cavity W treatment chamber+vent valve X
Whole equipment installs.
The present invention has an innovation greatly in single pump band backwashed fluid treatment facility:
1. the present invention when using as a kind of side stream treatment facility in the circulating water system, is an operation under positive pressure in the fluid treating plant cavity during operation in single pump fluid treating plant; When the equipment back flushing, the recoil fluid is the fluid in the recycle system, and is operation under positive pressure in the fluid treating plant cavity, and recoil fluidic pressure size determines by being processed system fluid self pressure, and the recoil of not pumping up.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is that a kind of single pump operation under positive pressure of structure iron of the present invention is from pressing the recoil fluid treating plant
Fig. 2 is the structure iron that a kind of single pump operation under positive pressure of the present invention is used as a kind of by-pass flow formula fluid treating plant when pressing the recoil fluid treating plant in industrial circulating water, to be in parallel installed with
Embodiment:
Among Fig. 1, fluid intake pipeline A, fluid intake valve A
1, fluid intake pipeline A
2, process pump A
3, fluid intake pipeline A
4, fluid outlet pipeline C, blow-off line B, blowdown valve B

Like Fig. 1, make a single pump negative pressure operation from pressing the recoil fluid treating plant to form by four major parts:
1. fluid moves inlet part=fluid intake pipeline A+ fluid intake valve A
1+ fluid intake pipeline A
2+ process pump A
3+ fluid intake pipeline A
4(fluid intake pipeline A wherein the pending chamber of a termination fluid treating plant cavity W on)
2. the fluid operation outlet part=fluid recoil part=fluid outlet pipeline C (fluid outlet pipeline C wherein a termination fluid treating plant cavity W treatment chamber) that enters the mouth
3. blowdown exports part=blow-off line B+ blowdown valve B
1+ blow-off line B
2(blow-off line B is the pending chamber of a termination fluid treating plant cavity W wherein)
4. the pending chamber of fluid treating plant cavity W=fluid treating plant cavity W+fluid treating plant cavity W treatment chamber+vent valve X
Whole equipment installs.
The present invention implements operation like this:
1. operation and the control of the present invention in the industrial cycle water system:
As shown in Figure 2, with the pipeline C among Fig. 1, pipeline A
4A wherein end be connected on circulating line H respectively and go up produce structure iron 2, in the time will carrying out purifying treatment to the water in the recycle system, shut-off valve B
1, open valve A
1, process pump A
3, the water inflow pipe A among the circulating water system pipeline H
4, via pump A
3→ pipeline A
2→ valve A
1The pending chamber of → pipeline A → fluid treating plant cavity W → fluid treating plant cavity W is treatment chamber → pipeline C → return circulating water system pipeline H.
At this moment treated water imports pipeline H; Various materials such as glutinous mud, impurity, suspended substance, mikrobe, mushroom constantly are trapped the pending chamber of fluid treating plant W cavity in the circulating line; Make it be difficult for being deposited on the heat exchange system surface; Guarantee the heat exchanger effectiveness of circulating water system, thereby reach object of energy saving.
2, the sewage backwash process of the present invention in the industrial cycle water system:
As shown in Figure 2; After present device operation for some time, impurity increases in the pending chamber of fluid treating plant cavity W, and the pending chamber of fluid treating plant cavity W constantly rises with the pressure reduction of treatment chamber; The equipment clean decrease in efficiency; Need back flushing,, at this moment close process pump A with the treatment effect of restorer
3, valve A
1, open valve B again
1The recoil fluid gets into from pipeline C, via the pending chamber of fluid treating plant cavity W treatment chamber → fluid treating plant cavity W → pipeline B → valve B
1→ pipeline B
2
Whole backwash process is accomplished, and the impurity in fluid treating plant W, glutinous mud etc. is exhausted from system, and the fluid treating plant purification efficiency is restored.
