Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a kind of structural representation that adopts the heating power wastewater treatment equipment of heat pump of the utility model.
Wherein: 1-waste water vaporizer, 2-heat pump, 3-waste water recycle pump, 11-waste water deoxygenation district, 12-saturation steam district, 13-mist eliminator, 14-high-concentration waste water stagnant area, 15-heat transfer zone, the hydrophobic storage area of 16-, 17-high-concentration waste water distribution zone.
Embodiment
As shown in Figure 1, a kind of heating power wastewater treatment equipment that adopts heat pump of the utility model comprises: waste water vaporizer 1, heat pump 2 and waste water recycle pump 3.The waste water vaporizer is made up of waste water deoxygenation district 11, saturation steam district 12, mist eliminator 13, high-concentration waste water stagnant area 14, heat transfer zone 15, hydrophobic storage area 16 and high-concentration waste water distribution zone 17 from top to bottom.
The saturation steam that heat pump 2 is used for the steam dome of self-saturation in the future 12 improves steam parameter, and high-parameters steam is sent to heat transfer zone 15 and waste water deoxygenation district 11.
Waste water recycle pump 3 is used for the high-concentration waste water from high-concentration waste water stagnant area 14 is sent to high-concentration waste water distribution zone 17.
The oxygen that waste water deoxygenation district 11 can remove in the waste water prevents the oxidized corrosion of material of waste water vaporizer 1, heat pump 2 and waste water recycle pump 3.Oxygen in the waste water is by the venting hole discharging at 11 tops, waste water deoxygenation district, but the venting hole pressure-stabilisation in partial equilibrium waste water vaporizer 1 middle and high concentration waste water zone also.Waste water deoxygenation district 11 is located at the top of waste water vaporizer 1, saved the space, reduced middle-chain, waste water after the desulfurization is fallen high-concentration waste water stagnant area 14 by gravity, can avoid in traditional wastewater treatment equipment the line clogging that causes because waste water deoxygenation district 11 and waste water vaporizer 1 are arranged apart.
High-concentration waste water is in the heat transfer tube of heat transfer zone 15, flow from bottom to up, make to be full of high-concentration waste water in the heat transfer tube, the flow velocity of high-concentration waste water is controlled by the flow type selecting of waste water recycle pump 3 in heat transfer tube, can be controlled in the rational flow rates of 1.5m/s～2.5m/s; Avoided high-concentration waste water to rely on run by gravity following time from top to bottom, flow velocity is uncontrollable, the low flow velocity on heat transfer tube top, the heat transfer tube bottom is because universal gravity constant flow velocity height, cause in the heat-exchanging tube bundle of bottom and do not have full of liquid, fouling easily, and the high concentrated wear that can increase the bottom heat-exchanging tube bundle of flow velocity.
