Compared with the prior art, the invention improves the safety factor, which is difficult to cause the damage for the people and the equipment; the invention can avoid the waste which is caused by the entrance of the steam into the oil collection tank; the invention improves the heat efficiency, reaches the self-circulation without the outside energy and reduces the cost.

Description

Closed energy-saving heating heat-exchange system
Technical field
The present invention relates to the heating equipment technical field, be specifically related to a kind of closed energy-saving heating heat-exchange system.
Background technology
By an oil recovery measuring station winter heating is example, at present, adopt high steam direct heating after reducing pressure, be that throttled steam directly enters radiator, after the radiator heat release, enter accumulator tank, have following problem: 1, residual steam enters a jar release, waste heat energy, the cost height: 1 measuring station heating installation is annual to be used 6 months, and 3 monthly average are used steam 20 sides every day when being cold, and used steam 7 sides 3 average every days when weather was not too cold, one side's steam is 78 yuan, measuring station year heating cost be 18.95 ten thousand yuan.2 safety coefficients are low: 180 ℃～230 ℃ of the dry gas temperature that steam boiler produced, pressure 4～8Mpa, and the wall thickness of radiator is little, as once hot spot is arranged, will cause high steam to unload leakage, easily produce casualty accident, the steam after unloading leakage is full of the interior space at short notice, and staff's sight line is unclear, can't withdraw, the personnel that easily cause suffocate.3, after residual steam enters big jar, enter atmosphere through a big jar manhole, steam is taken part crude oil out of oil tank in discharge process, has polluted oil tank, has buried hidden danger again.
Summary of the invention
In order to overcome the problem that the cost height, the safety coefficient that exist in the prior art are low, pollute oil tank, the invention provides a kind of energy-conservation, cost is low, safety coefficient is high closed energy-saving heating heat-exchange system.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of closed energy-saving heating heat-exchange system, comprise decompressor, radiator, accumulator tank, its special character is: also comprise heat exchanger and temperature control valve, heat exchange liquid inlet, the outlet of heat exchange liquid of described heat exchanger constitute a closed circulation loop with described radiator; Be provided with heat dump in the described heat exchanger, the inlet of described heat dump is connected with the outlet of decompressor, and the outlet of heat dump links to each other with accumulator tank by described temperature control valve.
Be provided with the hot and cold water heat exchange box between described temperature control valve and the accumulator tank.
Heat dump in the described heat exchanger is the pawl type.
The heat exchange liquid of filling between described heat exchanger and the heat dump is superconducting fluid.
Compared with prior art, advantage of the present invention is as follows:
1, the present invention adopts two cyclic designs, and high temperature, high steam do not enter heating system, avoid high temperature, high steam to leak, and the personnel that cause scald or suffocation accident takes place, and have improved the safety coefficient of heating system.
2, heat exchanger safety coefficient height among the present invention, withstand voltage 2.5MPa satisfies the requirement of heating pressure; Heating system adopts negative pressure, low temperature (70 ℃～90 ℃) design, is difficult for causing personnel and equipment damage.
3, the present invention utilizes existing steam decompressor to make low-pressure steam enter heat exchanger, condensed water after the heat exchange enters accumulator tank through autoamtic temperature controlling valve (the control temperature is between 80 ℃～100 ℃), avoid steam to enter accumulator tank and cause waste, improve the thermal efficiency.
4, the present invention utilizes superconducting liquid-vapor to be expanded to power, need not outside resources, reaches self circulation, reduces cost.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention;
Fig. 2 is the structural representation of heat exchanger among the present invention.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is described in further details.
Referring to Fig. 1, the invention provides a kind of closed energy-saving heating heat-exchange system, comprise decompressor 1, radiator 2, accumulator tank 3, also comprise heat exchanger 4 and temperature control valve 5, the heat exchange liquid inlet of described heat exchanger 4, the outlet of heat exchange liquid constitute a closed circulation loop with described radiator 2; Be provided with heat dump 7 in the described heat exchanger 4, the inlet of described heat dump 7 is connected with the outlet of decompressor 1, and the outlet of heat dump 7 links to each other with accumulator tank 3 by described temperature control valve 5; Be provided with hot and cold water heat exchange box 6 between described temperature control valve 5 and the accumulator tank 3.
Referring to Fig. 2, the heat dump 7 among the present invention in the heat exchanger 4 is the pawl type, makes the heat exchange liquid 8 of filling between heat exchanger 4 and the heat dump 7 big with heat dump 7 contacts area, and it is effective to be heated, and the heat exchange liquid 8 of filling between heat exchanger 4 and the heat dump 7 is superconducting fluid.
During work, utilize the steam decompressor that high steam is depressured to 0.4MPa, temperature is 143 ℃, as the heat exchange thermal source, after the superconducting fluid in the heat exchanger was heated, liquid state became the mist attitude, speed with 27～30m/s begins to propagate, release heat is on the way carried out heat release through fin to indoor, and temperature control reaches the indoor heating requirement.Condensed water in the heat exchanger after the heat exchange enters accumulator tank through temperature control valve, temperature control valve control temperature is at 80 ℃, when being lower than 70 ℃～80 ℃ of serviceability temperatures, temperature in jar, exits, stop venting when being higher than 70 ℃～80 ℃, thereby reduce the steam use amount more than 60%, save cost, improved steam utilization.Can build the boiler room in place with good conditionsi, the hot and cold water heat exchange box of the condensed water after the heat exchange in temperature control valve enters the boiler room, boiler is heated into steam with water, can be recycling, perhaps be used in the place that other need use steam.
