Abstract
A freezer saline brine accurate alarm system includes an evaporator, a brine pump, a liquid distributing ring, a liquid collecting ring and a plurality of freezers; the liquid distributing ring and the liquid collecting ring are respectively hermetically communicated with liquid entering pipelines and liquid exiting pipelines of the freezers through pipelines with ball valves; a flow meter is arranged between the liquid distributing ring and the liquid entering pipeline of each freezer as well as between the liquid collecting ring and the liquid exiting pipeline of each freezer; a data collector transmits flow information of the flow meters to a brine flow monitoring system in a monitoring room; and the monitoring system is used for analyzing the real-time difference value of the entered liquid quantity and exited liquid quantity of each freezer, and transmitting alarm instructions to an alarm according to analysis results. The freezer saline brine accurate alarm system of the utility model can accurately and quickly display flow data of each freezer, and can timely perform warning when the brine flow of a certain freezer is abnormal, and can accurately display the name of the freezer in which abnormities exist, such that the abnormities can be timely troubleshot and handled conveniently, and therefore, the possibility of permeation of brine into freezing walls can be lowered, and the freezing walls can be well protected.
Description
Technical field
The invention belongs to a kind of freezing apparatus salt solution leakage warning system, especially a kind of warning system that is used for Real-Time Monitoring freezing apparatus 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 strata shaft construction, use very extensive, technology maturation.Yet, in the Frozen Deep construction,, freezing wall low due to brine temp distortion is large, construction management not the factor such as science exist, easily make the disconnected event of running affairs of the excessive generation of freezing pipe distortion, cause salt solution in the freezing pipe thawing freezing wall that permeates the ground, when serious, freezing wall puts in a skylight the swelling in the stratum is entered in pit shaft, 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 on the salt water conduit tube, flowmeter to be installed, judge the leakage situation of salt solution by the variation of flow, but because single freezing apparatus fluctuations in discharge is little on the total flow impact, therefore can't judge the salt solution leakage situation of single freezing apparatus; 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 between casing, there is mutual balance device in liquid level, 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 freezing apparatus salt solution does not have timely alarm function.
Summary of the invention
The object of the invention is to provide a kind of freezing apparatus salt solution leakage warning system, penetrates into the chance of underground erosion freezing wall to reduce salt solution.
Technical solution problem of the present invention adopts following scheme:
a kind of freezing apparatus salt solution is revealed accurate warning system, comprise evaporator, the brine pump brine distributing ring, brine collecting ring and a plurality of freezing apparatus, described brine distributing ring is communicated with the feed liquor line seal of each freezing apparatus by the pipeline with ball valve, described brine collecting ring is communicated with the fluid line seal of each freezing apparatus by the pipeline with ball valve, its design feature is, between the feed liquor pipeline of brine distributing ring and each freezing apparatus, be respectively equipped with a flowmeter between the fluid pipeline of brine collecting ring and each freezing apparatus, described flowmeter is used for feed liquor amount and the liquid outlet quantity of each freezing apparatus of Real-Time Monitoring, and be transferred to computing machine brine flow monitoring system in Control Room by data acquisition unit, described brine flow monitoring system is used for analyzing the feed liquor amount of each freezing apparatus and the real-time difference of liquid outlet quantity, and be used for sending alarm command to alarm according to analysis result.
Design feature of the present invention also is:
Be provided with the ultimate value of freezing apparatus feed liquor amount and liquid outlet quantity difference in 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 ultimate 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 freezing wall designing requirement.
Safeguard that freezing period refers to: after freezing wall forms, for keeping its designing requirement, continue to carry to freezing apparatus 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 freezing apparatus data on flows; when certain freezing apparatus brine flow is undesired; can in time report to the police; and can accurately show the freezing apparatus title of abnormal; convenient in time investigation, processing; reduce the chance that salt solution infiltrates freezing wall, freezing wall is played a very good protection.
