In the industry, low temperature exhaust heat amount is large, quality is low, is difficult to upgrading and recycles.At present, existing solar energy, geothermal energy and the low temperature exhaust heat of utilizing freezes, heats technology, be mainly used in megastore, office building and large-scale resident's building, and waste heat amount is large in industrial production (especially thermal power plant), utilize industrial exhaust heat freeze or heating capacity large, supply exceed demand, causes waste heat recovery cooling and warming to be difficult to promotion and implementation.Lithium bromide refrigerator not only can utilize low temperature exhaust heat, can also save electric energy.Under the situation that China's energy-saving and emission-reduction are increasingly serious, lithium bromide refrigeration technique has been subjected to its distinctive advantage and has paid close attention to widely.
Power plant runs the loss that there is steam and condensate water in production process, losing the power plant working medium minimizing caused, can supplement demineralized water in boiler, steam turbine equipment and therrmodynamic system thereof for supplementing these.Supplementing water has two kinds of modes to enter therrmodynamic system usually: one enters oxygen-eliminating device, and one enters condenser.Moisturizing enters condenser can improve condenser vacuum, improves oxygen-eliminating device effect, promotes the advantage of steam-turbine unit efficiency.But general condenser water replenishing temperature is at 20 ~ 25 DEG C, and turbine discharge temperature is 35 ~ 40 DEG C, and both temperature difference are less, supplementing water and steam discharge mixed heat transfer effect undesirable, especially in summer, moisturizing and steam discharge can not fully heat exchange, and the advantage causing moisturizing to enter condenser is had a greatly reduced quality.Therefore, need one can ensure condenser water replenishing and the abundant heat exchange of steam discharge, the condenser water replenishing system of economic environmental protection again, has realized the effects of energy saving and emission reduction of whole unit.
Utility model content
The technical problems to be solved in the utility model is: in the industry, and low temperature exhaust heat amount is large, quality is low, being difficult to upgrading and recycling, for solving the problem, providing a kind of condenser water replenishing system of energy efficiency.
The purpose of this utility model realizes in the following manner:
A condenser water replenishing system for energy efficiency, is made up of condenser 1, water supply tank 2, lithium bromide refrigerator 3 and low temperature exhaust heat thermal source 4; Its middle-low temperature heat thermal source 4 is connected with refrigeration plant by pipeline, and the supplementing water in water supply tank 2 sends into refrigeration plant through supplementing water pipeline, refrigeration plant and lithium bromide refrigerator 3, and supplementing water sends into the water injector 6 of condenser 1 throat more by the road after absorbing cold.
The connecting pipeline of water supply tank 2 and low temperature exhaust heat thermal source 4 and lithium bromide refrigerator 3 is provided with control valve 5.
Supplementing water pipeline is provided with attemperator.

Detailed description of the invention
As shown in Figure 1, the utility model is a kind of condenser water replenishing system of energy efficiency.Be made up of condenser 1, water supply tank 2, lithium bromide refrigerator 3 and low temperature exhaust heat thermal source 4, low temperature exhaust heat thermal source 4 is connected with lithium bromide refrigerator 3 by pipeline, supplementing water in water supply tank 2 sends into lithium bromide refrigerator 3 by the road, sends into the water injector 6 of condenser 1 throat after absorbing cold more by the road.
Concrete process:
1. lithium bromide refrigerator 3 is set on condenser 1 water pipe, lithium bromide refrigerator 3 utilizes low temperature exhaust heat thermal source 4 to freeze as driving force, condenser 1 supplementing water is cooled to less than 20 DEG C by the cold energy produced, cooled supplementing water is sent into the water injector 6 of condenser 1 throat, water injector 6 is spiral-flow type atomizer, jet angle is 90 ~ 120 °, as 90 °, 100 °, 110 ° or 120 °, supplementing water sprays in condenser 1 through water injector 6 atomization, carries out heat exchange with turbine discharge.
2. water supply tank 2 and low temperature exhaust heat thermal source 4 are provided with control valve 5 with lithium bromide refrigerator 3 connecting pipeline, can the operating mode refrigerating capacity to condenser 1 rate of water make-up and lithium bromide refrigerator 3 different according to Steam Turbine regulate.
3. because supplementing water absorbs cold energy, supplementing water pipeline needs to carry out isothermal holding, can arrange insulation village on supplementing water pipeline.Water injector 6, adopt spiral-flow type atomizer, jet angle is 90 ~ 120 °.
4. lithium bromide refrigerator 3 provides refrigeration driving force by low temperature exhaust heat thermal source 4, and low temperature exhaust heat thermal source 4 comprises the steam, hot water etc. of low temperature waste gas, industrial discharge; When low temperature exhaust heat thermal source 4 is the flue gas of industrial discharge, need to carry out abrasion resistant corrosion resistant erosion process to the import and export pipeline of flue gas.
Directly entering the moisturizing of condenser 1 and turbine discharge can not fully heat exchange, and make condensate undercooling large, oxygen content is also higher, and the advantage causing moisturizing to enter condenser 1 is had a greatly reduced quality.Therefore condenser 1 moisturizing is cooled, ensure that moisturizing and the abundant mixed heat transfer of turbine discharge have great significance; Utilize low temperature exhaust heat and lithium bromide refrigerating principle, the operating cost of whole system is low and efficiency is high, while providing cost savings, has significant energy-conserving and environment-protective meaning.
