A kind of direct current cooker of the utility model starts hydrophobic heat recovery system, including steam-water separator, hydrophobic development unit, Also include heat exchanger, the hot water inlet of the heat exchanger connects the steam-water separator, the hot water outlet connection of the heat exchanger The hydrophobic development unit, after the hydrophobic inflow heat exchanger of the steam-water separator output is lowered the temperature, flows out to described dredging Water flash vessel.
Further, the exchanger heat water inlet is connected with the steam-water separator by hot inlet channel, described to change Hot device hot water outlet is connected with the hydrophobic development unit by hot outlet conduit, and the hot inlet channel is provided with import cut-off Valve, the hot outlet conduit is provided with outlet shutoff valve.
Further, the steam-water separator connects hydrophobic development unit by bypass duct, and the bypass duct is provided with Bypass stop valve.
Further, the cold water inlet of the heat exchanger, cold delivery port are connected with boiler feedwater pipeline respectively.
Further, described heat exchanger is surface-type heat exchanger.
Further, also including condenser, the condenser connects hydrophobic development unit.
Further, it is provided with storage tank between described steam-water separator and described heat exchanger.
Further, described inlet shutoff valve, outlet shutoff valve and bypass stop valve are electrically operated valve.
By such scheme, the utility model at least has advantages below:From the saturation water row that steam-water separator is isolated To storage tank, the surface-type heat exchanger on boiler feedwater main pipeline is flow to by inlet shutoff valve, changed by surface-type Hot device and boiler feedwater exchanged heat after it is hydrophobic flow into hydrophobic development unit by heat-exchanger rig outlet shutoff valve, eventually through dredging Water pump drains into condenser by hydrophobic, and the system will can be carried out without the hydrophobic heat in boiler water circulating pump direct current cooker start-up course Reclaim, reduce drain temperature, shorten the time of boiler cold-state startup, save fuel;In addition flash vessel entrance is reduced hydrophobic Temperature, improves the capacity enlargement effect of boiler hydrophobic development unit, solves the hydrophobic recovery system to condenser of startup because there is vapour Liquid two-phase causes the problem of pipeline vibration, reduces heat dissipation, has reached the effect of energy-saving and emission-reduction.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below Describe in detail bright as after.
Brief description of the drawings
