Description
Technical field
It is the recycling field of the heat energy and the water of main medium that the utility model relates to steam condensate, refers in particular to a kind of totally-enclosed water jetting type condensed-water recovering device that makes the condensate return pipe net to discharge smoothly and pressurize remote conveying once more.
Background technology
Steam is heat medium very general in the productive life, and steam is emitted the steam condensate that has just become high temperature after the heat, these condensate water is sent back to boiler once more reheat (heat absorption) and become steam, just can recycle.This is very important, reasonably measures to effectively increase energy savings and reduce material consumption.Yet, in fact exist many problems.
One of problem: each road is uneven presses.Steam is divided into different pressure ratings, and according to the characteristic of steam, the temperature of the condensate water that different pressures produces down is just different.The condensate water 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 indirect steam (also claiming flash steam).This just causes the condensate water pipe network in fact to be full of the pressure pipe network of flash steam, and the condensate water of high pressure can stop the condensate water of low pressure to enter pipe network.In order to improve this situation, adopt open condensate water to reclaim usually, 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, reclaimed then.The big like this condensate water that accounts for condensate water quality 10%～30% becomes flash steam and has wasted, and influences environment.
Two of problem:, no doubt can reclaim condensate water if adopt closed recovery pressurized delivered condensate water once more.But inevitable can't the discharge because of flash steam of sealing caused building the pressure of condensate water pipe network, causes the condensate water of heat exchanger end to discharge, and recovery system is whole paralyses, and loses the meaning of existence.That is to say, simply give the condensate water supercharging, be difficult to the problem that solves water to be obstructed.
Three of problem: the inconvenience of using electric pump to carry.The use occasion of steam condensate may not have supply of electric power, if just need lead-in wire separately with electric pump, at some petrochemical plants, all motors and electrical equipment all must satisfy requirement of explosion proof, causes cost to rise, and has perhaps increased hazards.Reclaim because condensate water is normally open-air, electric pump itself and fluid level controller thereof are placed in the open, are easy to lose efficacy, and cause water spill-over stream easily, make electrical equipment and electrical do not had by water logging, cause damaging.Condensate water is in the open type water collect tank, and even without flash steam, when adopting the electric pump suction to pressurize, condensate water continues flash distillation, often causes the serious cavitation of impeller of electrical pump root again, and impeller life is die-offed.
Steam condensate is a HTHP hot water, interior can be very high, its energy approximately is 25%～30% of a corresponding steam energy, is necessary very much to reclaim to utilize again.Yet according to incompletely statistics, the rate of recovery of China's steam condensate is less than 30%, in today of the energy of advocating thriftiness energetically, and a kind of really extremely inharmonic behavior; And on-the-spot " hot water crossing current, white cigarette curls upwards " also can have a strong impact on corporate image.
In view of this, the design artificially solves the problem that above-mentioned known technology exists, and develops, tests the well-designed finally the utility model that goes out with being engaged in the experience that this area is researched and developed for many years, made, going through repeatedly.
