Described shower water EGR comprises spray pump and shower, and an end of institute's spray pump is connected with water leg by pipeline; The other end of described spray pump is connected with the watering dish by shower.
The sidewall of described water leg sets gradually overfall, water supplement port and discharge outlet from top to bottom.
On the sidewall at described tower body middle part access door is set, between access door and surface cooler, water blocking device is set.
The utlity model has following advantage: Adopt fin that shower water is cooled off, increase the temperature difference between shower water and the medium temperature, quicken heat exchange efficiency; Access door is set, makes things convenient for the maintainer to enter in the tower and safeguard; Maintenance cost is low; 3. increase intake, thus increasing heat radiation effect; 4. draining automatically, equipment can not be damaged by frost when shut down winter.5. reduce the enterprise operation cost.6. when the medium temperature difference is big, use this kind refrigerating mode faster temperature to be cooled off the easier control of temperature.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
As shown in Figure 1, the anti-freeze type sealed cooling tower is made of blower fan 1, shower 2, fin 3, air-inlet grille 4, outlet 5, inlet tube 6, water leg 7, spray pump 8, access door 9, water supplement port 10, overfall 11, discharge outlet 12, magnetic valve 13, purge valve 14, draining valve 15 and surface cooler 16.The bottom of described tower body is provided with water leg 7; Blower fan 1, watering dish 17, fin 3, air-inlet grille 4 and surface cooler 16 are set in the described tower body; The top of described tower body is provided with blower fan 1, increases intake, discharges the heat steam in the tower; The below of described blower fan 1 is provided with watering dish 17, and the shower water in the shower 2 flows into watering dish 17; The below of described watering dish 17 is provided with fin 3, the shower water in the cooling watering dish 17; Described air-inlet grille 4, surface cooler 16 are arranged between fin 3 and the water leg 7; Described surface cooler 16 comprises coil pipe, inlet tube 6 and outlet 5, the staggered inclination of described coil pipe, and medium moves from the bottom to top; The end of described outlet 5 and inlet tube 6 is arranged at Ta Bishang; The end of described outlet 5 is provided with purge valve 14 and inflatable mouth, and when opening purge valve 14, a large amount of fresh airs enter in the tower by inflatable mouth; The end of described inlet tube 6 is provided with magnetic valve 13 and draining valve 15, and when shutting down, magnetic valve 13 is opened automatically, and the recirculated water in the coil pipe is from top to bottom discharged from draining valve 15 automatically, prevents that winter equipment is cold bad.
