Compared with prior art, the utility model using water recovery apparatus continuous and stable to boiler supplement high-temperature condensation water with Boiler replenishing water pump is substituted, using boiler water level controller and the continuous moisturizing of Frequency Converter Control high temperature recovery pump, while passing through moisturizing Pump maintains moisturizing to enable surge tank with lowest water level so that high temperature recovery pump is to continuous boiler replenishing water, so as to realize that replacement is normal Boiler feed pump is advised, continuous and stable supplement high-temperature condensation water improves boiler heating system efficiency, realizes maximum energy-saving effect.
Brief description of the drawings
Accompanying drawing 1 is the high-temperature condensation water recovery device structural representation of alternative boiler feed pump described in the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment, in the case where not conflicting, the feature in embodiment and embodiment in the application can be mutually combined, below will ginseng Examine accompanying drawing and describe the utility model in detail in conjunction with the embodiments.
As shown in figure 1, a kind of high-temperature condensation water recovery device of alternative boiler feed pump, including high temperature recovery pump 1, benefit Water pump 2, buffer tank 3, injector 4, liquid level detector 5, control cabinet 6, condensing hot air furnace pipe 7 and water supply tank 8, the buffer tank Water inlet pipe 31 and outlet pipe 32 are provided with 3, the outlet pipe 32 includes boiler connecting tube 321 and drainpipe 322, the boiler Connecting tube 321 is connected with boiler, and the high temperature recovery pump 1 is arranged in boiler connecting tube 321, boiler connecting tube 321 and draining Valve is respectively arranged with pipe 322, to control the folding of respective pipeline respectively, described one end of outlet pipe 32 is connected with buffer tank 3, The other end is connected with water supply tank 8, and the small pump 2 is arranged on water inlet pipe 31, and small pump 2 is used for the water pump in water supply tank 8 Enter in buffer tank 3, the injector 4 is arranged on the junction of water inlet pipe 31 and buffer tank 3, condensing hot air furnace pipe 7 and injector 4 Connection, the liquid level detector 5 is connected with buffer tank 3, and liquid level detector 5 is designed perpendicular to horizontal plane, level detection dress Put 5 and be provided with from top to down in five sensing points, i.e. L1, L2, L3, L4, L5, each sensing point and be provided with level sensor, It is provided with the control cabinet 6 and automatically controls chip, is automatically controlled chip and passed respectively with high temperature recovery pump 1, small pump 2 and water level Sensor is connected.
Operation principle of the present utility model is as follows:
1st, system energization initial operating stage, high-temperature condensation water is back to surge tank 3 by hydrophobic pressure itself, liquid level progressively on L1 positions are risen to, start small pump 2 to the moisturizing of surge tank 3;
2nd, water under high pressure is sprayed by the use of small pump 2 to mix as the carbonated drink in the motive fluid of injector 4 suction condensing hot air furnace pipe 7 Compound, makes condensed water is smooth to be back to surge tank, causes while reducing flash distillation using the low temperature water cooling condensed water of water supply tank 8 and is System superpressure;
