Background technology

A. technical field

The present invention is the field about process fluid cooling generally.More particularly, the invention relates to a kind of heat-exchange system and method, for optionally with wet type and/or dry mode process for cooling fluid.

B. background technology

Prior art

Cooling tower, being considered to open heat-exchange system, is the method that the most effective process fluid from heat (normally water) discharges heat.They inherently high efficiency be due to heat is flow through the direct underground heat of the process fluid flow of plastic tower packing and passed by downward trickle and move to the outer air stream up flowing through this medium.

Process fluid by heat is discharged heat by evaporation part component fluid (usually about total flow 1%) by cooling tower.Cooling tower can carry out the cooling every square feet tower packing of about 2.5 tons, but fluid cooling can only be carried out 1.5 tons every square feet (being less than 40%).

Closed-loop path fluid cooler, is considered to closed type exchange system, in-site installation serial or parallel connection flowing cooling tower, thus conserves water in warmer field operation temperature course.Closed-loop path fluid cooler is indirectly discharged heat by heat transfer via tube wall by warm process water and is fixedly exposed to water smoke to the usual fluid cooler heat exchanger of outer air stream to prevent corrosion from being produced to resist by galvanized steel.But galvanizing coating is only in outside.Therefore, the cycling use of water of open system that exposes to the sun of continuity ground vapour is rapidly inside deteriorated steel pipe.For this reason, for the fluid cooler that aeration water is operated in open system by described pipeline inside, stainless steel tube coil or polymer pipe coil are needs.

Wish a kind of heat-exchange system, it can optionally operate with wet mode (such as cooling tower) or with drying mode (such as liquid chiller).Operator optionally can cut heat-exchange system between each pattern, and it depends on desired cooling capacity, ambient climate, and plume is eliminated and/or water evaporation/loss.

The pipeline forming fluid cooler coil also can be used as the medium of surface area, is similar to filling plastic material in cooling tower.If water is sprayed on pipeline, extra steam heat exchange will be sprayed to pipeline and when being evaporated in spray water from process fluid heat transfer by tube wall.Therefore, need that there is heat-exchange system, wherein process water can be guided through at first to become inside pipeline closed-loop path fluid cooler and again via the assembly of spray water outside pipeline, pipeline has the advantage of process water by system twice.

When heat-exchange system is with wet mode and mixing wet type/drying mode operation, the air of evaporation process is used as to have dust, pollen and rubbish are wherein, and it leaves over detritus in lower water mobile by being rinsed during tower packing, it is collected in storage tank and becomes maintenance issues, and it can stopped nozzles and heat transfer pipeline.Therefore, need a kind of heat-exchange system, it is integrally in conjunction with debris filter and automatically rinse or cleaning and filtering component and only have seldom or do not have operator to get involved.

No. 3994995th, the U.S. patent discloses a kind of wet type/dry cooling tower, and it has upper tubular heat-exchange section and is positioned at above lower inclination inserts section.In upper tubular section after part cooling, liquid is led on underlying film inserts section or streamed, and it depends on cooling requirement.

No. 4112027th, the U.S. discloses a kind of drying of separation and wet type discharge-channel in the cold tower of heat exchange.No. 4122027th, the U.S. patent discloses a kind of merging directly and indirect cooling device and method.European patent EP 092246 discloses a kind of method of drying/wet cooling tower, and it has being connected in series of at least part of dry part and wet type part.
