Description
Technical field
The utility model relates to a kind of refrigerating plant, and more particularly, it relates to a kind of efficient plate-sheet-type evaporative condenser.
Background technology
In modern society, the application of Refrigeration Technique has related to each department and the daily life of national economy.Evaporative condenser mainly contain heat exchanger, water circulation system and air blast three part composition.The coiled pipe group that heat exchanger is made up of light pipe or finned tube, pipe is assembled in one by the vertical cabinet of shaped steel and welded steel plate, and water injector is equipped with on top, and bottom is a drip tray.Refrigerant vapour enters in pipe above coiled pipe, and the liquid of condensation then flows in reservoir through collector tube.Cooling water water circulating pump is sent to the top of condenser, sprays above coiled pipe group through nozzle, and the outer surface film forming layer along coiled pipe group is dirty.Water rear portion of being heated becomes steam, and remaining water flows down along coil outer surface, and comes together in the water pond of bottom, delivers to nozzle again recycle through water pump.When current are through coiled pipe group, because the gasification of water is absorbed heat, make the refrigerant vapour cooling in pipe and liquefaction.Cold-producing medium cooling procedure within the condenser, is in fact divided into two stages: be cooled to saturated vapor by superheated vapor, is condensed into saturated liquid or subcooled liquid again by saturated vapor.Therefore, in order to reduce the consumption of cooling water, a few row's coil pipe can also be increased on the top of evaporative condenser water fender, first superheated vapor from refrigeration compressor is cooled in this coil pipe, make it reach close to the saturation temperature under condensing pressure, and then enter lower disc pipework condensation and become saturated liquid.Evaporative condenser evaporative condenser is theoretical according to falling film evaporation, and the outside tube water film evaporation by condenser pipe is dispelled the heat, and every kg water evaporation can take away the heat of 2430kJ, and it is 0.12 ~ 0.16m3/ (m that unit are joins cooling water inflow
2h), total power consumption economizes on electricity about 10% than water-cooled, than air-cooled type economize on electricity more than 30%, current elliptical tube evaporative condenser heat transfer coefficient can reach 800 ~ 1000 (W/m
2dEG C.But in the exploitation and use procedure of evaporative condenser, because volume is large, weight is large, causes a lot of inconvenience in transport, installation process; In addition in use, if the evaporative condenser quantity of parallel connection is many, then floor space can be very large, in the age of this inch of land is an inch of gold, how when do not change even improve its heat exchange amount, the volume of reduction evaporative condenser becomes problem demanding prompt solution.
Utility model content
Existing coiled evaporative condenser space hold is large, unit volume hot exchange power is low, constrain applying of self to a certain extent, for overcoming this defect, it is compact that the utility model provides a kind of inner lining structure, space utilization is more reasonable, the efficient plate-sheet-type evaporative condenser that unit volume hot exchange power is higher.
The technical solution of the utility model is: a kind of efficient plate-sheet-type evaporative condenser, comprise air duct, casing, shower, heat exchange plate and tank, air duct is connected to above casing, shower and heat exchange plate are located in casing, shower is positioned at above heat exchange plate, heat exchange plate inside is provided with working medium runner, and tank is located at bottom half.During work, for the working medium of externally freezing in heat exchange plate internal flow, shower sprays cooling water and becomes water film to heat exchange plate surface, and water film is thinner, is easy to evaporation and gasifies, absorb heat, make the refrigerant vapor in heat exchange plate cool, liquefy during gasification.Unevaporated water then flows down along heat exchange plate, be collected in tank, relative to traditional coiled evaporative condenser, this plate-sheet-type evaporative condenser due to unit are area of dissipation large, and radiating surface opposed flattened, space arrangement can be compacter regular, therefore in same floor space, can improve hot exchange power further.
As preferably, in air duct, be installed with axial-flow exhaust fan.Axial-flow exhaust fan is in casing top exhausting, form negative pressure, in casing, produce air-flow from bottom to top, when blowing over from water film surface, the steam that heat exchange plate gasifies outward can constantly be taken away by air-flow, accelerate the formation of steam, and when the temperature of air-flow is lower than in heat exchange plate during temperature, can also play certain cooling effect, therefore arranging axial-flow exhaust fan can enhanced heat exchange effect, in addition can original little water droplet in entrapped air, concentrate and carry out Water Sproading.
As preferably, set up above shower and have dehydrater.In steam uphill process, temperature constantly reduces, liquefy gradually, the effect of dehydrater is that in the water that as far as possible the steam liquefaction of carrying secretly in air-flow come and air, original water droplet separates a step-down temperature of going forward side by side as far as possible, again drops into as cooling water and utilizes, minimizing water dispel loss.
As preferably, tank is provided with water pump, the circulating line that water pump is connected with, and circulating line end is connected on shower.The water of tank inner accumulated again can be spread across on heat exchange plate along circulating line under water pump promotes, and carry out evaporative condenser, such water is just fully used.
As preferably, tank is provided with water supplement port.In tank, recycle-water can reduce gradually along with the continuing to carry out of water circulation, can toward moisturizing in water supplement port after certain hour, the periodic duty of retaining plate chip evaporative condenser.
As preferably, bottom of gullet is provided with sewage draining exit.Can constantly there is impurity to be brought in water cycle process, and be deposited on bottom of gullet, sewage draining exit is set and be convenient to discharge impurity, avoid long-term alluvial, destroy water quality.
The beneficial effects of the utility model are:
Compact conformation, space utilization is more reasonable.The heat exchange plate shape of plate-sheet-type evaporative condenser is relatively regular, and many groups can arrange tightr when being installed in parallel, and compared to the condenser of coiled, floor space is less, and weight is lighter.
Heat exchanger effectiveness is higher.The area of dissipation of the heat exchange plate of plate-sheet-type evaporative condenser is large, and have binding site in heat exchange plate, when working medium flows through binding site, also great turbulence level can be there is under low-speed situations, heat transfer effect also significantly promotes, meanwhile, relative to the condenser of coiled, there is not cooling water and collect in tube wall curved surfaces formation local in plate-sheet-type evaporative condenser, so that affects the problem of study of water film distribution and even surface evaporation effect.
Save energy consumption, reduce use cost.Arrange shower above heat exchange plate in the utility model, moisture is joined more rationally efficient, and box house is furnished with dehydrater, and water rate of wafing is less, thus can reduce the waste of cooling water, saving water resource.
