Abstract
A closed type water pump waste heat recovery system is characterized in that a water pump cooling fan is omitted, a waste heat recovery device is mounted on a water pump stator shell, a heat exchange device is mounted in a water tank, and the heat exchange device, a circulating pump and the waste heat recovery device are connected in series through circulating pipes to constitute a closed circulating system; when the system works, the closed circulating system is filled with softened water firstly, the circulating pump is started, so that the softened water flows in the closed circulating system comprising the heat exchange device, the circulating pump and the waste heat recovery device, heat produced by a stator winding during operating of the water pump is collected by the softened water flowing through the waste heat recovery device, and then cold water in the water tank is heated for use through heat exchange performed by the heat exchange device.
Description
Technical fieldThe present invention relates to a kind of water pump waste heat recycling system, particularly a kind of enclosed water pump waste heat recycling system.
Background technology
Water pump in prior art is operationally owing to its stator winding is producing in the process that rotating excitation field drives water pump vane rotation by electric current, stator winding coil (is generally copper core) will make a part of electric energy be converted into heat energy and produce substantial amounts of heat, stator winding coil temperature can be made to raise rapidly, general solution is all installation radiator fan on water pump, run up by water pump rotor and drive fan high-speed cruising, the temperature rise of water pump stator winding coil is reduced in the way of motor stator winding is carried out air blast cooling but by this, reach the purpose that water pump runs continuously, this mode can bring the rising of ambient temperature, fan runs up and can produce significantly high noise simultaneously.
Summary of the invention
It is an object of the invention to: a kind of enclosed water pump waste heat recycling system of design, make its can to water pump operation time the heat that produces reclaim, exchange to utilize and reach the purpose of energy-saving and emission-reduction, noise when simultaneously can reduce again pump operation and the impact on surrounding.
The present invention realizes above-mentioned purpose in the following way, cancel water pump radiator fan, installing waste-heat recovery device at water pump stator casing, heat-exchange device is arranged in water tank, and heat-exchange device, circulating pump, waste-heat recovery device are undertaken being connected in series formation closed circulation system by circulation pipe.
Adopt constituted above, first in closed circulation system, softening water is filled during system work, then circulating pump is started, softening water is made to flow in heat-exchange device, circulating pump, waste-heat recovery device closed circulation system, during water pump operation, stator winding generation heat carries out heat collection by flowing through the softening water of waste-heat recovery device, then pass through heat-exchange device to carry out heat exchange and be heated the cold water in water tank using, reduce water pump temperature rise, purpose that noise, thermal energy collecting utilize.Accompanying drawing explanation
Fig. 1 is the enforcement state diagram of the present invention.
Detailed description of the invention
A kind of enclosed water pump waste heat recycling system as shown in Figure 1 includes: water pump 1, waste-heat recovery device 2, heat-exchange device 3, water tank 4, circulating pump 5 and connecting tube, switch board (not marking in figure) composition.The radiator fan of water pump 1 is cancelled, waste-heat recovery device 2 is arranged on the stator winding shell of water pump 1, the stator winding shell making waste-heat recovery device 2 and water pump 1 forms closed structure, water inlet 6 and outlet 7 it is provided with at waste-heat recovery device 2, heat-exchange device 3 is arranged in water tank 4, the water inlet of heat-exchange device 3 and the outlet 7 of waste-heat recovery device 2 are connected by connecting tube, the water outlet of heat-exchange device 3 and the water inlet of circulating pump 5 are connected by connecting tube, the water outlet of circulating pump 5 and the water inlet 6 of waste-heat recovery device 2 are connected by connecting tube, make waste-heat recovery device 2, heat-exchange device 3 circulating pump 5 forms closed circulation system.The connecting tube of the water inlet of circulating pump 5 is additionally provided with the softening water moisturizing mouth of pipe 8, system first passes through the softening water moisturizing mouth of pipe 8 and fills softening water in closed circulation system when using, water tank 4 fills cold water, then circulating pump 5 is started, softening water is made to flow in closed circulation system, when water pump 1 runs, its stator winding produces substantial amounts of heat and takes away, by flowing through the softening water of waste-heat recovery device 2, the purpose reaching water pump cooling, make temperature to be reached by heat-exchange device 3 in the cold water of water tank 4 when the softening water after heating flows through heat-exchange device 3 cold water is heated, flow through heat-exchange device 3 soften water through heat exchange lower the temperature after flow to circulating pump 5, after being pressurizeed by circulating pump 5, low temperature softening water is flowed to waste-heat recovery device 2 by water inlet 6, with this repeated work.User can be supplied as hot water after cool water heating in water tank 4 to use, also as hot water moisturizings such as boilers, energy-conservation purpose can be reached with this consumption reducing the energy.Reach to reduce the purpose of noise owing to water pump 1 eliminates radiator fan.If the water outlet that water pump is multiple stage at this moment circulating pump 5 can connect with the import of multiple stage water pump waste-heat recovery device, the water inlet of heat-exchange device 3 and the outlet of multiple stage water pump waste-heat recovery device connect, and thus can carry out being connected in parallel the purpose reaching the more heat energy of Collection utilization according to the quantity demand of thermal source water pump.
