Description
Technical field
The utility model relates to a kind of return water system, especially relates to a kind of condensed water in high temperature heating domestic hot water return water system.
Background technology
How realizing making full use of of waste heat recovery is one of present problem demanding prompt solution, such as, energy centre heat exchange station 140 DEG C of heat exchanger condensing water temperatures in Ningbo are at about 140 DEG C, about 72t condensate water can be produced every day, a now heating energy source center bathroom hot water, but bathroom use amount is less, every day, use amount was at about 5t, water temp. heating is from 20 DEG C to 60 DEG C, recycle (251.67-84.47) × 5 × 1000=0.83GJ/ days, other waste heats are directly sent to power plant's cooling, make full use of.
Chinese patent CN 202973955U discloses a kind of for steam condensate and residual neat recovering system thereof, and this system comprises condensed water flashing tank, condensate pump, plate type heat exchanger and spray thrower four parts.High-temperature steam condensate water, by condensed water flashing tank, carries out gas-liquid separator; Condensate water after separation enters plate type heat exchanger after condensate pump pressurization; After plate type heat exchanger, condensate water is cooled to assigned temperature, a cooled condensate water part sees assigned address off, a part is back to the spray thrower of condensed water flashing tank deck, in spray thrower, cooled condensate water and flash steam mixing, the steam condensate becoming higher temperature is back to condensed water flashing tank, but this system still needs to consume more steam.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of consumption, the energy-saving effect significant condensed water in high temperature heating domestic hot water return water system that greatly reduce steam are provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of condensed water in high temperature heating domestic hot water return water system, be connected with high-temperature condensation water pipeline, be made up of heat exchanger plate, aqueduct and heat exchanger, conveying domestic hot-water backwater in described aqueduct, this domestic hot-water's backwater and the heat exchange in heat exchanger plate of high-temperature condensation water pipeline, domestic hot-water's backwater of heating is delivered in heat exchanger and heats further.
Spiral heat-exchange tube is provided with in described heat exchanger plate.
The temperature of described high-temperature condensation water pipeline is 140 DEG C.
Described high-temperature condensation water pipeline in heat exchanger plate by the heating temperatures of domestic hot-water's backwater to 80-85 DEG C.
Described domestic hot-water's backwater in heat exchanger through Steam Heating to 90 DEG C.
Described aqueduct is provided with water pump.
Compared with prior art, the utility model increases heat-exchange device between air compressor machine thermocirculator and water circle device, realize the recovery of residual heat of air compressor, and reclaim the heat of compression of centrifugal air compressor afterbody, any adverse effect is not produced safely to air feed, also greatly reduce the consumption of steam, serve energy-conservation effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-high-temperature condensation water pipeline, 2-heat exchanger plate, 3-water pump, 4-heat exchanger, 5-aqueduct.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
A kind of condensed water in high temperature heating domestic hot water return water system, its structure as shown in Figure 1, be connected with high-temperature condensation water pipeline 1, primarily of heat exchanger plate 2, aqueduct 5, heat exchanger 4 and water pump 3 form, conveying domestic hot-water backwater in aqueduct 5, this domestic hot-water's backwater and high-temperature condensation water pipeline 1 heat exchange in heat exchanger plate 2, spiral heat-exchange tube is provided with in heat exchanger plate 2 in the present embodiment, the temperature of high-temperature condensation water pipeline 1 is 140 DEG C, high-temperature condensation water pipeline 1 in heat exchanger plate 2 by the heating temperatures of domestic hot-water's backwater to 80-85 DEG C, domestic hot-water's backwater of heating is delivered in heat exchanger, steam is utilized to be heated to 90 DEG C further.
Like this, 140 DEG C of condensate water steam cause heat exchanger plate 2 by high-temperature condensation water pipeline 1, by heat exchanger plate 2 heating domestic hot water backwater, the backwater of domestic hot-water enters heat exchanger 4 again, because the water entering into heat exchanger 4 has been hot water, so greatly reduce the consumption of steam, serve energy-conservation effect.
Use the utility model, 140 DEG C of condensate water are heated plant area domestic hot-water again, makes 140 DEG C of condensing water temperatures be down to 85 DEG C, improve energy recovery efficiency, reduce thermal waste phenomenon.Carrying out enthalpy calculating by producing 140 DEG C of condensing capacities every day, [(589.32-356.44) × 72t-0.83GJ] × 350 days=5565GJ can be utilized every year, save steam 2208t/.
