Technical field
Glass furnace cogeneration repeats to utilize system with the jetting overflow water again, belongs to glass furnace cogeneration technology field, is specifically related to a kind of jetting overflow water and repeats to utilize system again.
Background technique
The glass furnace afterheat generating system is that the waste heat flue gas in the kiln is produced steam through exhaust heat boiler; And become superheated vapor through heating process again; The heat energy of steam changes the mechanical energy that rotatablely moves of axle in steam turbine; The process that mechanical energy becomes electric energy in generator is the same with power plant's (thermoelectricity) of operation usually, and afterheat generating system has boiler circuit, vacuum pumping system, electrical system, oil system, circulation and DCS Turbine protection system etc.
The vacuum pumping system capital equipment has vapour condenser, water-jet pump and air ejector, and the effect of air ejector is the noncondensing gas of constantly extracting out in the vapour condenser, is beneficial to vapor condenses Cheng Shui; Simultaneously; Air ejector was extracted the air in vapour condenser and the turbine body out before steam turbine starts, set up vacuum rapidly, and made vapour condenser keep certain degree of vacuum; Shorten starting time, avoid steam and water bursting.
Usually, the air ejector that cogeneration is selected for use is a water jet air ejector, and the jetting extract system needs special water box, water pump and moisturizing pipeline; Its system adopts closed cycle, again because vapour, the heating of gas mixture and the frictional heating of pump operation must cause the temperature rise of jetting tank water, must replenish fresh cold water like this; The balance that keeps cistern water level, the hot water of water tank are just discharged by spill pipe, directly enter in the trench; And meanwhile, the power of generating is big more, and ambient temperature is high more; Need additional fresh water just many more, and the water of directly draining is also just many more, has so not only wasted resource but also has increased operating cost.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of existing technology, provide a kind of and reduce circulating cooling make-up water amount, conserve water resource, reduce operating cost, realize that the glass furnace cogeneration that resource repeats to utilize again repeats to utilize system with the jetting overflow water again.
The utility model solves the technological scheme that its technical problem adopted: this glass furnace cogeneration repeats to utilize system with the jetting overflow water again; Comprise the vapour condenser, water-jet pump, jetting water tank and the jetting tank drains pipe that connect successively, it is characterized in that: between the vapour condenser sewage door below described jetting water tank and the vapour condenser, set up jetting collection box, transfer pump and safety check successively.Overflow water through in the jetting collection box correlation water tank reclaims, and the overflow water of collecting is added to circulating water pool, as the supplementing water of power generation cycle cooling water system, to reduce the rate of water make-up of circulating water, realize resource repeat utilize again.
Described jetting collection box one upper lateral part is provided with spill pipe, and the bottom connects jetting tank drains pipe.
Described vapour condenser top connects the circulating water return pipe, and the bottom connects circulating water inlet.
Described vapour condenser sewage door is provided with two, and one of the left side links with safety check.
Compared with prior art, the beneficial effect that the utility model had is:
1, economizes on resources, reclaim, the overflow water of collecting is added to circulating water pool through the overflow water in the jetting collection box correlation water tank; Supplementing water as the power generation cycle cooling water system; To reduce the rate of water make-up of circulating water, realize resource repeat utilize again, both significantly reduced the rate of water make-up of circulating water; Practice thrift resource again, reduced the production run cost;
2, in the sustainable recycling that realizes resource; When having far-reaching environment protection significance; Through evidence; Overflow water in the jetting water tank can use as the supplementing water of power generation cycle cooling water system fully, can not cause any harmful effect to turbine system, guarantees the Security and the reliability of producing;
3, rational in infrastructure, novel in design unique, simple to operation, practicability is stronger, is fit to apply on a large scale, has important market value.
