Description
Technical field
The invention belongs to technical field of chemical, be specifically related to a kind of novel horizontal evaporative condenser.
Background technology
Condenser is of wide application in daily life, and the power plant will obtain condensation with the steam that many condensers are discharged turbine; In refrigeration plant, come the refrigeration steam of condensation ammonia and freon and so on condenser.Make hydro carbons and other chemical evapn condensations with condenser in the petro chemical industry.In still-process, be transformed into liquid device to steam and call condenser, all condensers are all taken away the heat of gas or steam and are turned round.
Concerning some application; Gas must be through a long pipe (coiling into solenoid) usually; So that let heat be lost in the air all around, carry steam with metal heat pipe, for the efficient additional heat sink on the pipeline of being everlasting that improves condenser is dispelled the heat with acceleration; Fin is the flat board of processing with good heat-conducting metal, and this type condenser generally also will force air to be walked through fin and the torrid zone with blower fan.
During industrial chemicals is produced, condenser one of the production equipment that is absolutely necessary.Condenser is different by its cooling medium, can be divided into water-cooled, air-cooled type, vaporation-type three major types; Water cooled condenser is divided into open shell and tube conde er, closed shell and tube condenser, tube-in-tube condenser again; Its evaporimeter is divided into horizontal-type evaporator and vertical type evaporator again.Evaporative condenser is when utilizing the outer shower water of coil pipe partly to evaporate in the absorption coil, the heat of high-temperature gas cold-producing medium and make the cold-producing medium in the pipe be cooled to liquid state by gaseous state gradually.Because of the cooling water great majority contain calcium, magnesium ion and acid carbonate.When cooling water flow during, the generation of carbonate is arranged through the metal surface.In addition, the oxygen that is dissolved in the cooling water also can cause metal erosion, forms iron rust.Because the generation of rust deposite, the heat exchange effect descends.The spraying cooling water housing outside of having to when serious is understood cramming when fouling is serious, make the heat exchange effect ineffective.The data of research show that the incrusted deposit thing is huge to the loss influence of heat transmission, can cause the increasing of energy expenditure along with sedimental increase.Even very thin one deck incrustation scale will increase equipment in the operating cost of fouling part more than 40%.Keep not containing the service life that mineral deposit can well improve effect, energy savings, prolongation equipment in the cooling duct, practice thrift production time and expense simultaneously.A lot of problems appear in traditional for a long time cleaning way such as mechanical means (scrape, brush), water under high pressure, Chemical cleaning (pickling) etc. to equipment cleaning the time: can not thoroughly remove deposits such as incrustation scale; Acid solution causes corrosion to form leak to equipment, and residual acid produces anticaustic or underdeposit corrosion to material, finally causes more exchange device; In addition; The cleaning waste liquid is poisonous, needs substantial contribution to carry out wastewater treatment, thereby causes a large amount of manual works, the loss of material.
Summary of the invention
The purpose of this invention is to provide a kind of novel horizontal evaporative condenser, compact conformation, liquid contacts with heating surface, and heat transfer coefficient is high, and the cooling water import and export temperature difference is big, adopts CO
