Description

Thermal power plant and refrigeration enterprise cooling-tower circulating water low level renewable energy heating installation
Technical field
The utility model relates to civilian heating system, specifically utilizes the heating installation of cooling-tower circulating water low level renewable energy, belongs to environment-friendly type reusing of energy source field.
Technical background
Circulating water in turbine condenser has been taken away a large amount of heat energy in thermal power plant by cooling tower at present.The thermal efficiency in thermal power plant on average has only about 35%, and most of heat energy of fuel has caused the huge waste of the energy through cooling tower being discharged in the atmosphere in vain.And be discharged into atmosphere, and increase global warming, caused huge environmental pollution.The outlet mean temperature of thermal power plant circulating water in turbine condenser and big-and-middle-sized refrigeration enterprise cooling-tower circulating water is about 33 ℃, this recirculated water water yield is big, annual temperature fluctuation is very little, contains huge thermal resource, is a kind of desirable renewable available discarded energy.But since middle low level renewable energy utilize the cost height, equipment investment is big, technical difficulty is bigger, the thermal resource of this part is not fully paid attention to and is utilized.
Summary of the invention
The utility model purpose is to disclose a kind of thermal power plant and refrigeration enterprise cooling-tower circulating water low level renewable energy heating installation.Extract heat for low level renewable energy in this through source pump, the primary side supply water temperature of heat supply is reached about 60 ℃, through thermal energy conversion device thermotropism user heat supply.Under metastable water temperature, can be efficient, stable, operation economically.Low grade heat energy is converted into high-grade heat energy, is not moving thermal power plant and the refrigeration business equipment is done under the prerequisite of change, through heat transfer apparatus heat energy is exported, to satisfy user's heat demand to existing.
The utility model is to be made of water resource heat pump 10 and regeneration energy harvester 9, heating plant 11, it is characterized in that: water resource heat pump is the closed circulation pipeline that is connected in series the heat transferring medium that constitutes by evaporimeter 4 and compressor 5, condenser 6, expansion valve 3; Described regeneration can connect condenser circulating water outlet pipeline by cooling water cycle water pump 1 by harvester, low-grade hot water after the pressurization is linked into water resource heat pump 10 water inlets through electric control valve 2 one tunnel, another road is connected to water-water jet 8, and water resource heat pump 10 water outlets are connected to water-water jet 8 by pipeline; Heating plant 11 is formed circulation pipe network by hot user's radiator group 12 through pumps for hot water supply net 7.
Description of drawings
Figure one is the utility model schematic diagram.
The specific embodiment
As seen from the figure, on condenser circulating water outlet pipeline, increase a pipeline, after 1 pressurization of cooling water cycle water pump, the recirculated water low grade heat energy is extracted and is delivered to water resource heat pump 10 units, under the driving of electric energy, water resource heat pump 10 units are converted into high-grade heat energy with low grade heat energy, through the heat energy conveying device to user's heat supply.The recirculated water that has discharged heat energy directly is discharged in the water tower pond through water-water jet 8 without water tower 13 coolings.Water resource heat pump 10 units are converted into high-grade heat energy with low grade heat energy, through heating plant 11 to user's heat supply.
Huge pollution has also been caused to environment in the thermal power plant when bringing clean energy resource for the mankind since being born.How the heat energy with fuel is used as much as possible, improves the ratio of using energy source and pollutant effulent discharging, this be at home and abroad the working energy person in the problem of making great efforts to explore always.Therefore how the heat with low-temperature circulating water is used, and improves rate of energy, improves the thermal efficiency in power plant, realizes energy-saving and emission-reduction, and this is the problem that everybody pays close attention to.Thermal power plant recirculated water is a huge resource, and annual temperature fluctuation is very little, and mean temperature is a kind of desirable renewable available discarded energy about 33C.The utility model extracts heat from thermal power plant recirculated cooling water and big-and-middle-sized refrigeration plant coolant outlet water resource, the hot machine of water source heat pump technology and power plant of maturation and water conservancy project technology is in one, under metastable water temperature, efficient, stable, carry out heating operation economically.
The utility model can be regulated output automatically with the outdoor temperature variation. Its advantage is: energy-conservation Efficiently, the low-grade exhaust heat of discharging in the existing recycling technology in the thermal power plant system is reclaimed, Make the heat resource of coal by further exploitation recovery, increase substantially the comprehensive thermal effect in thermal power plant Rate and economic benefit; Make efficiency of energy utilization reach more than 4 times of traditional approach; Clean environmental protection, Avoided any flue dust of discharging and harmful substance, social benefit is remarkable; Water saving, province ground, saving money The source; Safe and reliable, unit operation is stable, maintenance is simple, and the generating plant circulation-water system is not done greatly Change, as long as accurate Calculation determines pump-out and water conservancy project quantity of circulating water and mixes the water yield, and downstream The pipeline increase is drawn water a little and is increased the mixing water drainpipe to the water tower tank, makes the former recirculated water in power plant Water temperature and the flow of system all do not change, and the generating plant circulation-water system safety operation is not produced Any impact; Reduce investment outlay, operating cost is low, the automaticity height, operating cost is few.
