(2), after recirculated water uses, do not need to carry out cooling process again to recirculated water, reduce the use of human cost and resource;
(3) decrease the blowdown of waste water, water resources is reused.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 2-water purifying tank; 4-steam heater; 6-air outlet; 10-recycle pump; 12-steam trap; 14-water pipe; 16-cooling spray; 18-back pool; 22-two-port valve; 24-control device; 25-purification tank for liquid waste; 27-proofing unit; 28-analytical equipment; 30-setting device; 32-water level compensation system.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done further specifically, as shown in Figure 1, the utility model comprises and to be communicated with water source and water purifying tank 2 for carrying out reverse-osmosis treated to the water in water source, described water purifying tank 2 is communicated with the air outlet 6 of a steam heater 4, described pond is also communicated with steam trap 12 by a recycle pump 10, described steam trap 12 is provided with a water pipe 14, this water pipe 14 is also communicated with a cooling spray 16, the back pool 18 that one can receive the water that described cooling spray 16 sprays is provided with immediately below described cooling spray 16, described back pool 18 is communicated with described water purifying tank 2, and between be provided with a lift pump.
The utility model can extract the hard water in the water sources such as rivers by water purifying tank 2, by carrying out reverse-osmosis treated after steam heater 4 steam heating, become the process water that directly can be used by condenser, then the waste water used through condenser through cooling spray 16 after high-altitude to be sprayed onto in back pool 18 cooling a little, be extracted in water purifying tank 2 by liquid absorbing pump again, carry out reverse-osmosis treated, circulation like this, this mode, use the use decreasing steam, thus decrease the use of coal, save cost, decrease the pollution of environment and decrease the blowdown of waste water, water resources is reused, adopt high-altitude to spray simultaneously, with the mode of air heat exchange, structure is very simple, without the need to setting up the cooling apparatus of complexity and then reducing the use of human cost and resource.
As further improvement of the utility model, described water pipe 14 is in series with two-port valve 22 and for controlling the control device 24 of described two-port valve 22 commutation, described cooling spray 16 is connected on one of them pipeline of described two-port valve 22, and another pipeline of described two-port valve 22 is communicated with a purification tank for liquid waste 25.
Two-port valve 22 is set, for controlling the flow direction of the trade effluent after condenser use, because the trade effluent of discharging have passed through use repeatedly, make the composition in it more complicated, when being unfavorable for reusing, need to be discharged, before discharge, consider Environmental Factors, first should carry out the process of sewage to it.
As further improvement of the utility model, described control device 24 comprises proofing unit 27, analytical equipment 28 and setting device 30, described proofing unit 27 comprise in PH tester, ORP tester and conductivity meter one or more, the information that described proofing unit 27 can detect by described analytical equipment 28 is carried out analysis with the information preset and is contrasted, when the information detected is all lower than presupposed information, then setting device 30 is given an order to described two-port valve 22, and water pipe 14 is communicated with described cooling spray 16; When the information that described proofing unit 27 detects have at least one higher than presupposed information time, then send commutation command to described two-port valve 22, described water pipe 14 be communicated with purification tank for liquid waste 25.
Adopt this structure, can analyze composition and the character of waste water accurately, and make according to it and judging accurately, this mode improves level of automation, without the need to manual operation, solves manually-operated inaccuracy and hysteresis quality.
As further improvement of the utility model, described water purifying tank 2 is also communicated with a water level compensation system 32, when the water level in described water purifying tank 2 is reduced to default numerical value, controls the diversion from water source of described water purifying tank 2.
