Preferred technical solution is to be additionally provided with refrigerator between the lower water box and the first delivery pump.In lower water box Refrigerator is set on the pipeline of high water tank conveying water, so that the water in high water tank is become low-temperature cooling water, makes the recirculated water System can also be cooling tower, and rectifying column, condenser etc. need cooling, condensation equipment to supply water, expand circulation The scope of application, improve the utilization efficiency of circulation.

Further preferred technical solution is that the lower water box is equipped with water level detecting probe, and the lower water box is logical It crosses the 5th solenoid valve to connect with water-supply systems, the 5th solenoid valve, water level detecting probe are electrically connected with control host.It follows Water in ring water system can gradually be lost during recycling, when the water level of water level detecting probe detection to lower water box Being reduced to setting height is, control host controls the 5th solenoid valve and opens, and water-supply systems carry out automatic water to lower water box Amount supply, when the water level in lower water box reaches preset height, control host controls the 5th solenoid valve tube wall, stops supply.

Further preferred technical solution is that the pipeline between the lower water box and the first delivery pump is equipped with feed water flow Monitor is measured, the pipeline between the second delivery pump and lower water box is equipped with circling water flow rate monitor, the flow of inlet water monitoring Device and circling water flow rate monitor are electrically connected with control host.Flow of inlet water monitor and circling water flow rate prison is arranged in circulation Device is controlled, when the difference for the water return amount that the inflow that flow of inlet water monitor is monitored is monitored with circling water flow rate monitor is greater than When preset value, control host is sounded an alarm, and prompting personnel in time overhaul pipeline, is checked pipeline water leakage situation, is avoided water Resource loss influences the progress that factory normally produces, and reduces factory's loss.

Further preferred technical solution is that the flow of inlet water monitor and circling water flow rate monitor are that time difference type is super Acoustic wave flow meter.

Further preferred technical solution is that water temperature monitoring probe is additionally provided on the inner sidewall of the high water tank, described Water temperature monitoring probe is electrically connected with control host.When the water temperature in high water tank is higher or lower than preset temperature range, control Host processed sounds an alarm, and prompting personnel check the refrigerator in circulation line, guarantees the regular supply of cooling water, avoids Influence to the operation of the equipment such as cooling tower in production system, avoids bigger loss.

Further preferred technical solution is that first delivery pump and the second delivery pump are air driven pump.

Advantages and beneficial effects of the utility model lie in that the utility model structure is simple, recirculated water management is automatically closed, It effectively prevent water resource waste and can be well protected pumping and instrument electric equipment, prolong its service life, reduce loss；By system In solenoid valve, delivery pump connect with control host, control host is connect with uninterruptible power supply, when the unexpected power-off condition of generation When, uninterruptible power supply provides electric power, to control starting and stopping for solenoid valve and delivery pump, effectively prevent water resource waste Meanwhile pumping and instrument electric equipment are also protected well, it prolongs its service life, reduces factory's loss.In lower water box to height Refrigerator is set on the pipeline of position water tank conveying water, so that the water in high water tank is become low-temperature cooling water, makes the circulation It can also be cooling tower, rectifying column, condenser etc. need cooling, condensation equipment to supply water, expand the suitable of circulation With range, the utilization efficiency of circulation is improved；Flow of inlet water monitor and circling water flow rate monitor is arranged in circulation, It is preset when the difference for the water return amount that inflow and circling water flow rate monitor that flow of inlet water monitor is monitored monitor is greater than When value, control host is sounded an alarm, and prompting personnel in time overhaul pipeline, is checked pipeline water leakage situation, is avoided water resource It is lost, influences the progress that factory normally produces, reduce factory's loss；Setting water temperature monitoring is popped one's head in high water tank, when high-order water When water temperature in case is higher or lower than preset temperature range, control host is sounded an alarm, and reminds personnel in circulation line Refrigerator is checked, and guarantees the regular supply of cooling water, avoids the influence run to equipment such as cooling towers in production system.
