Description

Thermal pump

The invention belongs to the liquid conveying technology, can utilize thermal source to make the power of carrying.

Do not find directly to utilize the feasible program of heat energy in the known technology as yet in the liquid transportation art.

The normal feedway of liquid medium for want of in simple and easy heating system has influenced thermal source and has been subjected to for the heat transfer between the point, makes the thermal efficiency of this system be difficult to improve.

The purpose of this invention is to provide a kind of is the practical technique scheme of carrying the direct driving force of liquid with the thermal source.

The present invention is achieved in that thermal pump comprises the pump housing, liquid in-out mouth, has the one-way valve of controlling liquid flow direction at liquid in-out mouth place; The pump housing comprise contain the liquid in-out mouth and between seal space, the blind pipe that communicates with seal space, the blind pipe cecum is the extreme lower position in the blind pipe, can be only to the thermal source of blind pipe cecum heating, other parts promptly of the present invention all directly do not obtain the heat energy of thermal source.Like this, during work, when the liquid of heating section blind pipe is vaporized rapidly, the other parts liquid of blind pipe still is in liquid state, sharply the gas that expands is released it blind pipe, is pushed out by the liquid outlet of seal space, the inertia that expands causes the pressure of blind pipe cecum to descend rapidly again simultaneously rapidly, at this moment can only enter a part of liquid by liquid entering hole and replenish the pressure that reduces, the cecum of blind pipe has heated liquid again, said process just reappears once more, repeats, promptly form the working procedure of thermal pump of the present invention, goal of the invention is achieved at this.

Blind pipe slenderness ratio＞20 of thermal pump of the present invention, blind pipe volume be the heating section volume 8-10 doubly more than, the volume of seal space is controlled within 2 times of the blind pipe volumes, the pump work that can make the present invention is under effective state.

The desirable specific surface area of blind pipe cecum heating section of the present invention is a heated surface area, with the bigger shape of the volume that is heated.Therefore the present invention can quicken the speed of blind pipe cecum vaporizing liquid.

The sealing pair of one-way valve of the present invention is curved surface or plane, is provided with guiding and limit position part on its moving element moving direction, with to-and-fro motion and the suitable conducting aperture of restriction sealing pair that guarantees that moving element is correct.Promptly can realize opening normally and reset after reliable sealing, and guarantee that the overflow section of on state sealing pair is suitable with corresponding liquid in-out mouth cross section.

The present invention directly utilizes expansion principle and the corresponding pipeline structure in the heated liquid phase transition process, realized conveying to liquid, it is a kind of pump of brand new, opened up the another new suitable application area of pump, scheme itself is skillfully constructed, simple in structure, implement easy, easy to use, remarkable, with low cost in the occasion effect that is suitable for.

Accompanying drawing provides the embodiments of the invention schematic representation;

Fig. 1 is the thermal pump structure diagram;

Fig. 2 is a thermal pump curved surface sealing pair one-way valve part-structure diagrammatic sketch;

Fig. 3 is that thermal pump uses in simple and easy heating equipment is to connect diagram.

This example is 100m ²The accelerating unit that the simple and easy heating system aqueous medium of the family of inhabitation area of heat-supply service circulates, the intake-outlet 3 of this device seal space, 5 with among the series connection access heating water route, the cecum 12 of blind pipe 10 places within the hearth box of thermal source-home furnace 15 of this heating system, non-heating section all applying in the cooking stove heat affected zone with thermal-protective material 11, avoid the heat affecting of cooking stove, blind pipe diameter 20mm, all the other sizes are all by slenderness ratio＞20, cecum heating section 12 volumes are the 1/10-1/8 of blind pipe volume, cecum also is the pipe shape, whole consistent with blind pipe, the opening of blind pipe communicates with the seal space 9 of the pump housing 2.The volume of seal space 9 is slightly less than 2 times of blind pipe volume, and the intake-outlet one-way valve adopts sphere 13 or plane sealing pair 6, and is provided with guide element 4 and limit position part 8.The intake-outlet aperture is suitable with pipeline that heating system joins 1,7, if line arrangement needs, the direction of the connection of pipeline can be carried out according to need, as shown in Figure 2.When beginning work, blind pipe cecum 12 made in the pipe heat supply water rapidly above boiling point because of being heated, the steam of vaporization sharply extends to the remaining part of blind pipe, the heating water of this part is pushed to seal space 9, backed down sealing pair 6 or 13 at water outlet 5 and enter heating system 7,14.The inertia that water is gone out in the blind pipe after finishing expansion causes the cecum internal pressure sharply to descend, temperature also decreases, force seal space water outlet sealing pair to recover sealing, and water inlet sealing pair 4 is forced to open, make the water of heating system incoming road 1 enter seal space, fill up the low pressure of blind pipe cecum, the normal cecum heating section 2 of pressure is heated once more, reexpand, repeat said process once more, the water origin road that makes heating system eventually is to the outlet, under the effect of this example, mode with pulsation flows by force, Gong Zuo result is like this: make the system water flow velocity bring up to 2.1 meters/minute by 1.4 meters/minute, the heat that thermovent 14 distributes by 7000 kilocalories/time bring up to 7770 kilocalories/time, backwater temperature difference is reduced to 26-28 ℃ by original 48-50 ℃ in the system.The water capacity that this example is got in touch system is 108Kg.

This example is linked among the Domestic heating system, just in case meet accident, system still can import and export along the seal cavity that series connection inserts and circulate, and keeps original duty. Present embodiment has solved the problem of the medium-term and long-term circulation ability difference that exists of simple and easy heating system, and structure, installation, operation are all very easy, and effect is remarkable, maintaining is also very simple, increases cost seldom.
