Description
Technical field
The utility model belongs to technical field of automation, relates to a kind of plate type heat exchanger monitoring early-warning system of plate type heat exchanger being monitored in real time and being carried out fault pre-alarming.
Background technology
Plate type heat exchanger is the high efficiency heat transmission equipment of the one in heat exchanger, in the process industrials such as chemical industry, petrochemical industry, metallurgy, electric power are produced, is widely used.Plate type heat exchanger can produce various faults in During Process of Long-term Operation, as leakage, fouling etc.Form certain thickness dirt or incrustation scale at heat exchange surface, increase thermal resistance, thereby reduced the heat transfer efficiency of heat exchanger, when serious, will cause heat exchanger leakage or blast, even make whole system paralyse, cause safely huge threat to national wealth and people's life.And because general territory scope is large, heat exchanger website disperses, distance, concentrate management efficiently so can't realize, monitoring means are relatively backward, mostly be according to safety operation specification, utilize hand-held instrument to monitor, manual control switch, this causes the security monitoring of heat exchanger also to have many blind areas, is easy to have an accident.Therefore how plate type heat exchanger is carried out to comprehensively monitoring, find in time heat exchanger operation exception, alarm, and inform fast administrative department and site operation personnel trouble point, take in time corresponding measure to process, ageing with management for improving safety management degree, there is very important effect, this is also one of most important mark in enterprise automation process.
At present, the method that domestic heat exchanger monitoring adopts is a lot, but mostly all not too perfect, such as heat transfer efficiency is to carry out artificial judgment by the temperature difference of medium, corrosion condition is mainly just to find by its medium having been produced to obvious impact after the serious leakage of heat exchange equipment appearance, and this may cause large area medium pollution.In addition, the existing problem of heat exchange equipment often causes production system non-plan repair frequent, and the production system operating cost of opening, stop work significantly increases, and energy waste is serious.
Summary of the invention
The purpose of this utility model is to provide a kind of plate type heat exchanger monitoring early-warning system, and plate type heat exchanger is carried out to comprehensively monitoring and intelligent early-warning.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of plate type heat exchanger monitoring early-warning system, comprise PLC controller, and PLC controller is connected with industrial computer signal; PLC controller is also connected with alarm, proportioning valve and sensor data acquisition device respectively, and this sensor data acquisition device comprises medium analysis instrument, multiple flowmeter, multiple temperature sensor and multiple pressure sensor; Medium analysis instrument, multiple flowmeter, multiple temperature sensor and multiple pressure sensors are all connected with PLC controller signals.
The utility model monitoring early-warning system utilizes PLC to process the data of integrated sensor collection, be transferred to industrial computer, produce visualization interface, the results such as data message and heat exchange amount such as the pressure of Real-time Feedback medium, temperature, flow, Auto-matching heat exchange medium flow, and in the time that plate type heat exchanger breaks down, carry out in time sound and light alarm and the issue of remote alarms information.
