Abstract
A brine leakage accurate alarm system for freezers comprises an evaporator, a brine pump, a liquid distribution ring, a liquid collecting ring and a plurality of freezers. The liquid distribution ring and the liquid collecting ring are in sealed communication with liquid inlet pipes and liquid outlet pipes of the freezers respectively through pipes with ball valves, flowmeters are respectively arranged between the liquid distribution ring and the liquid inlet pipe of every freezer and between the liquid collecting ring and the liquid outlet pipe of every freezer, a data collector transmits flow information of the flowmeters to a brine flow monitoring system positioned in a monitoring chamber, and the monitoring system is used for analyzing a real-time difference value of the liquid inlet amount and the liquid outlet amount of every freezer and sending alarm commands to an alarm according to analysis results. The brine leakage accurate alarm system can accurately and rapidly display flow data of every freezer; when brine flow of some freezer is abnormal, an alarm can be given timely, a name of the abnormal freezer can be displayed accurately, timely troubleshooting and treatment are facilitated, the chance that brine leaks into a freezing wall is reduced, and extremely good protection effect on the freezing wall is achieved.
Description
Technical field
The invention belongs to a kind of frigo salt solution leakage warning system, especially a kind of warning system that is used for Real-Time Monitoring frigo brine flow in the construction of pit shaft freezing method that is applied in.
Background technology
Freeze-wellboring is to solve one of effective method of unstable water bearing ground shaft construction, use very extensive, technology maturation.Yet, in the Frozen Deep construction, because the distortion of low, the frost wall of brine temp is large, execution control not the factor such as science exist, easily make freezing pipe be out of shape the disconnected event of running affairs of excessive generation, cause salt solution in the freezing pipe thawing frost wall that permeates the ground, frost wall puts in a skylight the swelling in the stratum is entered in pit shaft when serious, occurs thereby cause flooding the well accident, causes construction delay and huge economic loss.At present, salt solution leakage method in the monitoring brine system has two kinds: a kind of is at the salt water conduit tube flow meter to be installed, judge the leakage situation of salt solution by the variation of flow, but because single frigo changes in flow rate is little on the total flow impact, therefore can't judge the salt solution leakage situation of single frigo; Another kind is that the salt-water liquid level alarm is installed in brine tank, automatic alarm when the salt solution liquid level drops to certain position, but because the brine tank volume is large, and there is mutual bascule in liquid level between the casing, when the salt-water liquid potential drop is low to moderate certain position, the salt solution wastage is very large, and this leakage to single frigo salt solution does not have timely alarm function.
Summary of the invention
The object of the invention is to provide a kind of frigo salt solution leakage warning system, penetrates into the chance of underground erosion frost wall to reduce salt solution.
Technical solution problem of the present invention adopts following scheme:
A kind of frigo salt solution is revealed accurate warning system, comprise evaporimeter, the brine pump brine distributing ring, brine collecting ring and a plurality of frigo, described brine distributing ring is communicated with the feed liquor line seal of each frigo by the pipeline with ball valve, described brine collecting ring is communicated with the fluid line seal of each frigo by the pipeline with ball valve, its design feature is, between the feed liquor pipeline of brine distributing ring and each frigo, be respectively equipped with a flow meter between the fluid pipeline of brine collecting ring and each frigo, described flow meter is used for feed liquor amount and the liquid outlet quantity of each frigo of Real-Time Monitoring, and be transferred to computer brine flow monitoring system in the Control Room by data acquisition unit, described brine flow monitoring system is used for analyzing the feed liquor amount of each frigo and the real-time difference of liquid outlet quantity, and is used for sending alarm command to alarm according to analysis result.
Design feature of the present invention also is:
Be provided with the limiting value of frigo feed liquor amount and liquid outlet quantity difference in the described brine flow monitoring system, when the difference value of overstepping the extreme limit, the brine flow monitoring system is sent alarm command to alarm.
Described limiting value is 0.3m in positive freezing period
3/ h; Safeguarding that freezing period is 0.3～1.0m
3/ h.
Actively freezing period, refer to: from beginning to freeze to the time period that reaches the frost wall designing requirement.
Safeguard that freezing period refers to: after frost wall forms, for keeping its designing requirement, continue to carry to frigo the time period of refrigerant.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention can accurately, promptly show each frigo data on flows; when certain frigo brine flow is undesired; can in time report to the police; and can accurately show the frigo title of abnormal; convenient in time investigation, processing; reduce the chance that salt solution infiltrates frost wall, frost wall is played a very good protection.
