Power source is from solar energy which belongs to free and clean energy, and is low in carton content, environment friendly and inexhaustible.
Description
One, technical field:
The utility model relates to a kind of solar energy heating low boiling working fluid screw expansion power system.
Two, background technique:
Existing single cycle screw expansion power system all is the recovery at high-temperature, high pressure fluid, the low relatively fluid of the recyclable temperature and pressure of dual-circulation screw expansion machine, but cycle efficiency and low, practicability is greatly limited, and power technology is to evaporate low boiling working fluid as circulation by other heating technologys, and power consumption is serious and cycle efficiency is underground.
Three, model utility content:
The utility model is in order to solve the deficiency in the above-mentioned background technology, provide a kind of simple in structure, cycle efficiency is high, the solar energy heating low boiling working fluid screw expansion power system of energy-conserving and environment-protective.
For achieving the above object, the technical solution adopted in the utility model is: a kind of solar energy heating low boiling working fluid screw expansion power system, comprise vaporizer, condenser and screw expansion motor, described vaporizer, condenser and screw expansion motor are connected to closed-working medium peripheral passage successively, also be connected with the hot water circuit path on the described vaporizer, described hot water circuit path forms a closed-loop path by hot water pump and solar heat collector.
Be connected with the cool cycles pipeline on the described condenser, the inlet of cool cycles pipeline is provided with cooling waterpump.
Go back and be connected to the domestic water pipeline between the hot water pump of described hot water circuit path and the vaporizer.
Compared with prior art, advantage and the effect that the utlity model has are as follows: the utility model is simple in structure, the cycle efficiency height, energy-conserving and environment-protective, and energy sources is in solar energy, low-carbon (LC), environmental protection, belong to the energy free, cleaning, and be inexhaustible.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five, embodiment:
Referring to Fig. 1: a kind of solar energy heating low boiling working fluid screw expansion power system, comprise vaporizer 3, condenser 4 and screw expansion motor 1, described vaporizer 3, condenser 4 and screw expansion motor 1 are connected to closed-working medium peripheral passage 8 successively, also be connected with hot water circuit path 9 on the described vaporizer, described hot water circuit path 9 forms a closed-loop path by hot water pump 6 and solar heat collector, be connected with cool cycles pipeline 10 on the described condenser 4, the inlet of cool cycles pipeline 10 is provided with cooling waterpump 7, goes back and be connected to domestic water pipeline 11 between the hot water pump 6 of described hot water circuit path 9 and the vaporizer 3.
The utility model utilizes solar energy heating water, then with the low boiling working fluid heat exchange, low boiling working fluid is introduced the screw expander acting again.At first solar setup has the thermal isolation and heat storage effect, can be for night or overcast and rainy hot water demand, a part is drawn as the domestic hot-water after the water of solar energy heating and the low boiling working fluid heat exchange, another part is delivered to the solar energy header tank by hot water pump and is continued heating, constitute a circulation, described working medium peripheral passage is provided with working medium pump between vaporizer and the condenser, described cool cycles path, the entry end of cooling water or cooling air is provided with cooling waterpump.
Working principle: utilize solar energy heating water and low boiling working fluid heat exchange, the gas-liquid two-phase of low boiling working fluid changes and does work by screw expander.Hot water circuit path 9, at first toward solar setup 2 fills with water, absorb solar energy heating water to uniform temperature by vacuum thermal-arrest pipe, water after the heating enters vaporizer 3 carry out heat exchange with low boiling working fluid in the pipeline after, a temperature decline part is supplied with people by pipeline and is made life hot water, a part is sent into header tank by hot water pump and is continued heating, can regulate and distribute by pipeline adjusted valve.In working medium peripheral passage 8, low boiling working fluid in vaporizer 2 pipelines is heated by hot water, the working medium temperature is raise, arrive saturation temperature, become saturated vapour or gas-liquid two-phase, enter screw expander 1 expansion acting then, drive generator for electricity generation or promote compressor, pump or other energy consumption equipments.Do gas-liquid mixed working medium after the completion and flow out from the screw rod machine and enter condenser 4, condenser 4 in, make the vapor condensation of gas-liquid mixture, turning back to vaporizer 3 passing through working medium pump 5 by cooling water or cooling air.This system consumption be green, free solar energy, facility compact, generating efficiency height.
For example: solar energy heating efficiency eta in the market
1Can reach 0.75, insulating efficiency η
2Be 0.95, screw expander is that Jiangxi China electricity is produced, and generating efficiency is 0.8, suppose that flow is 100t/h, condensing temperature is 20 ℃, and is annual by operation consideration in 7200 hours, the consumption of deduction hot water pump and working medium pump and coolant pump, per hour the flow of one ton of hot water can be dealt into 0.9KW's.
By ten thousand yuan/year of 0.56 yuan of calculating: 0.9 * 7200 * 100 * 0.56=36.28 of electricity price
The utility model technology has following remarkable result: (1) meets the requirement of energy-saving and emission-reduction, zero-emission fully; (2) all paths all are a kind of peripheral passages of closure, more embody a kind of notion of cycle energy; (3) hot water by heat-insulating water tanks but also can adopt other residual heat resources heat exchange to strengthen the generating efficiency in its night as the heat exchange of low boiling working fluid night the time; (4) required hot water conditions is loose relatively, and the following hot water more than 60 ℃ of normal pressure is just passable; (5) since all hot water circuit paths in pipeline,, can be used as the domestic hot-water and use the not influence of the quality of water; (6) cycle efficiency height: solar energy heating efficient height, 85 ℃ hot water per ton can per hour generate electricity more than the 1KW.
