Description
Technical field
It is the heat energy of main medium and the recycling of carbonated drink that the utility model relates to steam condensate, relate in particular to a kind of different pressures grade condensate return pipe net that makes and to discharge carbonated drink smoothly, carry out carbonated drink and mix the remote multistage water of condensation enclosed recovering device of carrying.
Background technique
Steam is to use very general heat transfer, acting medium, and it has just become condensed water in high temperature after emitting heat.A large amount of heat energy is still contained in inside, and its energy approximately is 25%～30% of a corresponding steam energy, how these water of condensation recovery is used very important really measures to effectively increase energy savings and reduce material consumption again.Yet, exist problems in the practical application.
One of problem: the open recovery waste of water of condensation is serious.
According to the characteristic of steam, the temperature of the water of condensation that different pressures produces down is just different.The water of condensation of high temperature pressure in the process that refluxes constantly descends, owing to can consume nowhere in unnecessary, wherein a part of water must be converted into secondary steam (also claiming flash steam).The pressure pipe network that this vapour-water that just causes the water of condensation pipe network in fact to be full of flash steam mixes.The water of condensation of high pressure can stop the water of condensation of low pressure to enter pipe network.In order to improve this situation, common then adopt open water of condensation to reclaim, that is: in appropriate place the open type water collect tank is set, make flash steam to atmosphere emptying, realize that each road all presses, and then reclaimed.The big like this water of condensation that accounts for water of condensation quality 10%～30% becomes flash steam and has just wasted, and environment is also unsightly.
Two of problem: the open recovery of water of condensation is seriously polluted once more.
Because equipment is not airtight, makes water-soluble corrosive gass such as oxygen, carbon dioxide directly contact with water of condensation, is easy to generate oxygen corrosion and sour corrosion, has reduced water of condensation water quality, and has shortened the working life of equipment and pipeline.
Three of problem: the inconvenience of using electric pump to carry.
Water of condensation after the recovery is carried, if just need lead-in wire separately with electric pump, in enterprises such as petrochemical industries, all motors and electrical equipment all must satisfy requirement of explosion proof, causes the procuring equipment cost to rise, and has increased hazards.
Water of condensation is in the open type water collect tank, and even without flash steam, when adopting the electric pump suction to pressurize, water of condensation continues flash distillation, often causes the serious cavitation of impeller of electrical pump root again, and impeller life is die-offed.
Four of problem: carbonated drink mixed flow difficulty.
When steam water interface flows in pipeline usually, water of condensation in the pipe is pasted the bottom tube wall and is flowed at a slow speed, steam flow portion is from it blown at a high speed, the water of condensation water surface produces fold and progressively forms wave, when wave height reaches 12% when above of caliber, can quicken suddenly to increase, stop up this pipeline section, form the water plug, be commonly called as " water hammer ".This water hammer is with the speed motion of steam flow (10～20 meter per seconds, even higher), and momentum is very big, produces for pipe downstream elbow along the line, valve, expansion joint and instrument and impacts.
