Abstract
The utility model discloses a heat exchange device for condensed water and secondary water backwater. The device comprises a condensed water heat exchanger, wherein one side of the condensed water exchanger is connected with a condensed water inlet pipe and a condensed water outlet pipe, and the other side of the condensed water exchanger is connected with a secondary water backwater inlet pipe and a secondary water backwater outlet pipe. By arranging one condensed water heat exchanger, the high-temperature condensed water generated in the gas-and-water heat exchange process exchanges heat with the low-temperature water with the secondary network backwater temperature of 35 to 50 degrees, so that the outlet water temperature of the condensed water heat exchanger is lowered from 65-80 DEG C in the past to 45-60 DEG C, which is lowered by 15 DEG C on average, the part of heat is effectively absorbed by the secondary network backwater, heat energy is saved, energy conservation and consumption reduction are realized, the heat exchange device operates economically, and cost is lowered.
Description
Technical field
The utility model relates to the heating network technical field of heat exchange, the heat-exchange device of especially a kind of condensed water and secondary water backwater.
Background technology
The center heat exchange station is the master station of central heating system, is vapour--water heat exchange station, vapour source are the high-temperature high-pressure overheat steams of being carried by peak steam power plant; Through vapour--after the water heat exchange, with producing a large amount of condensed waters, the existing most of loopback of the condensed water power plant that is designed to; Wherein the defective part of water quality is effluxed, and few part is used for system water supplement, because the temperature of condensed water is higher; About 65-85 ℃, cause the waste of most of condensed water heat energy.
Summary of the invention
The purpose of the utility model is the deficiency to above-mentioned existence, and a kind of device that can effectively utilize condensed water heat energy is provided.
For realizing above-mentioned purpose; The technical scheme of the utility model is; The heat-exchange device of condensed water and secondary water backwater; Comprise the condensed water heat exchanger, a side of condensed water heat exchanger is connected with condensed water water inlet pipe and condensed water outlet pipe, and opposite side is connected with secondary water backwater water inlet pipe and secondary water backwater outlet pipe.
The utility model is through installing a condensed water heat exchanger, and the high-temperature condensation water that utilizes steam-water heat exchanging to produce carries out heat exchange with the water at low temperature of about 35-50 ℃ of secondary net return water temperature; Make the leaving water temperature of condensed water heat exchanger reduce to 45-60 ℃, on average reduce by 15 ℃, this part heat is effectively absorbed by secondary net backwater by original 65-80 ℃; Practice thrift heat energy; Realized saving energy and reduce the cost, economical operation has reduced cost.
The concrete structure of the heat-exchange device of the utility model condensed water and secondary water backwater is provided by following accompanying drawing and embodiment in detail.
Description of drawings
The structural representation of Fig. 1 distance rod assembly.
Among the figure: 1, condensed water water inlet pipe, 2, the condensed water outlet pipe, 3, secondary water backwater water inlet pipe, 4, secondary water backwater outlet pipe, 5, the condensed water heat exchanger.
The specific embodiment
Embodiment is as shown in Figure 1; The heat-exchange device of condensed water and secondary water backwater; Comprise condensed water heat exchanger 5, a side of condensed water heat exchanger 5 is connected with condensed water water inlet pipe 1 and condensed water outlet pipe 2, and opposite side is connected with secondary water backwater water inlet pipe 3 and secondary water backwater outlet pipe 4.
It should be noted that; Above-mentioned specific embodiment is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
