Description
Technical field
The present invention relates to plumbing technical field, in particular it relates at a kind of open type circulating cooling water quality
Reason technology, the technology is a kind of power-saving method of by-pass flow water system, more particularly it relates to a kind of self-powered recirculated water
By-pass flow water system and its application method.The circulating-water bypass water system and its method can make full use of the confession more than needed of recirculated water
Water pressure generates electricity, so as on the premise of suspended matter removal effect is ensured, reach remaining recoverable purpose.
Background technology
So far, large-scale recirculating cooling water system generally use open type cooling.However, the open type type of cooling because
Water and air contact is cooled down, absorbs substantial amounts of dust, silt, microorganism etc. in air, easily forms suspended matter with cooling
Current generate deposit attachment to water equipment in equipment and pipeline, cause the reduction of heat exchanger heat exchange efficiency, the cross-section of river
Reduce or even make equipment, corrosive pipeline perforation.
It is the effective way for preventing suspended matter from being accumulated in recirculated cooling water that recirculating cooling water system, which sets by-pass flow water system,
The purpose is to keep circulating cooling water quality, circulation is made effectively and economically to be transported under conditions of cycles of concentration is met
Row.When being run under the conditions of high concentration multiple, amount of makeup water and water amount of blowdown can be reduced, mitigates the pollution to environment.
It is to be extracted out part recirculated water in pond by being independently arranged filtered water pump according to conventional by-pass flow water system, even
It is continuous to return again to circulation after filter filters, so as to which suspended matter be removed.Therefore filter pump need to be run throughout the year, and be disappeared
Consuming electric power.Compared with the water supply pump of circulation, for filter pump because its power is small, the power of motor of outfit is also smaller, usually its
Pump efficiency is only 80% or so, and electric efficiency also only has 85% or so；And water supply pump electric efficiency can supply water up to more than 90%
The efficiency of pump also can obviously have more power savings advantages up to more than 85% with water supply pump water intaking.Secondly the setting distribution of filtered water pump dry point
Compared with concentration, the situation of water intaking and the short stream of return water is susceptible to, so as to cause the situation of local water body repeated filtration in absorbing well, absorption well, and
The distribution of water supply pump dry point is relatively uniform.
Meanwhile traditional recirculating cooling water system is to ensure the normal use of high-order recirculated water user's unit and return
Water can smoothly return to cooling tower, and water supply pump delivery has certain design margin, and because the presence of surplus, usually makes water supply
Pump not operates in optimal working point（Refer to attached drawing 1：Pump characteristic figure）.Particularly in low temperature season, due to system
Thermic load is smaller, and upper tower cooler is carried out without all cooling water return water, this part surplus then bigger.On the one hand there are surplus but
It is wasted, another aspect side stream then needs consumption electric energy to be pressurized, therefore is contemplated that and combines the two.
Chinese patent application CN200620104776.9 discloses a kind of water treatment facilities of side stream type, the technology used
Scheme is flocculator of the setting containing anodic-cathodic in by-pass flow water system, removes sundries and ion in recirculated water, realizes and improves
The purpose of water quality.However, it is not directed to the utilization of water supply overbottom pressure.
Chinese patent application CN201120220355.3 discloses a kind of Beside Filter System of Recirculating Water, which realizes by-pass flow
The energy-saving run of water system, the technical solution adopted is that, recirculated water return pipe is accessed into a water inlet distributor box, with U-shaped
Distributor box is connected by pipe with filter, and the water in distributor box is sucked clear water reserviors using siphon principle, energy saving mesh is realized with this
's.
However, although the program has carried out a degree of utilization to remaining pressure of piping system, since the water in return pipe is first
Into water inlet distributor box, filter is entered back into, the process into distributor box is process of the water with pressure to empty release, therefore,
Only make use of this portion of energy of height of water level in overbottom pressure, utilization is not implemented in original kinetic energy of recirculated water and pressure head in pipeline, so as to
Limit the energy-saving effect of the program.
Chinese patent application CN200410051720.7 discloses a kind of method of automatic allocating side filter for recirculated cooling water, adopts
Technical solution is to drive turbine pump using cooling tower height fall after cooling on recirculated water return water, and turbine pump is toward by-pass flow
Water system matches somebody with somebody water-supply source.The program can utilize return water overbottom pressure to a certain degree, but still simply using this portion of height of water level
Divide energy, energy-saving effect has larger limitation.
