Description

The emergent electrical control gear of refrigeration plant NH_3 leakage warning
Technical field
The utility model relates to the emergent electrical control gear of a kind of refrigeration plant NH_3 leakage warning.
Background technology
Ammonia has larger toxicity to human body, and ammonia can stimulate the eyes of people and upper respiratory apparatus, and ammoniacal liquor is splashed to human body skin can cause swelling so that scald; Secondly, when concentration reaches 0.3%-0.6% to ammonia in atmosphere, can suffocate after people's breathing, go into a coma so that dead.When ammonia density reaches 16%-25%, running into naked light can blast.
Traditional ammonia refrigeration system forms primarily of compressor, condenser, storage ammonia device, oil eliminator, choke valve, ammonia liquor separator, evaporimeter, intercooler, emergency ammonia drainer, oil catcher, various valve, Pressure gauge and high-low pressure pipeline.Wherein, the compressor in refrigeration system, condenser, choke valve and evaporimeter (freezer comb) are four most basic elements of character.Connect successively with pipeline between them, form a closed system, cold-producing medium ammonia constantly circulates in systems in which, generation state changes, exchange heat is carried out with the external world, its course of work is: after liquid ammonia absorbs the heat of cooled object in evaporimeter, be vaporized into the ammonia of low-pressure low-temperature, sucked by compressor, enter condenser after being compressed into the ammonia of high pressure-temperature, cooled water for cooling exothermic condensation is high pressure ammoniacal liquor within the condenser, is the ammoniacal liquor of low-temp low-pressure through choke valve throttling, again enter evaporimeter endothermic gasification, reach the object of circularly cooling.Like this, ammonia completes a kind of refrigeration cycle through pervaporation, compression, condensation, throttling four basic processes in systems in which.
In current driving force workshop, there is NH_3 leakage warning device at ammonia refrigeration station, this warning device is acoustic-optic alarm, exhaust fan in workshop is Non-follow control, when NH_3 leakage, acoustic-optic alarm sends sound and light alarm signal, operating personnel go to open exhaust fan according to alarm signal and are exhausted, and when NH_3 leakage, Compressor Group is work as usual still.Adopt above-mentioned electric controling mode, NH_3 leakage can not be processed efficiently in time, and there is the problem of energy waste.
Given this, the present inventor carries out deep research to the problems referred to above, then has this case to produce.
Utility model content
The emergent electrical control gear of refrigeration plant NH_3 leakage warning that the purpose of this utility model is to provide a kind of efficiently can be processed NH_3 leakage, reduce energy waste.
In order to achieve the above object, the utility model adopts such technical scheme:
The emergent electrical control gear of refrigeration plant NH_3 leakage warning, comprise ammonia refrigeration system disposed in the interior, in order to monitor NH_3 leakage and the acoustic-optic alarm of reporting to the police and the exhaust fan in order to ammonia to be drained into outdoor, refrigeration compressor is provided with in ammonia refrigeration system, acoustic-optic alarm comprises the sensor of alarm and the setting of corresponding ammonia refrigeration system, also comprise controller, described acoustic-optic alarm and described refrigeration compressor are all electrically connected to described controller, described exhaust fan is provided with automatic switch, and this automatic switch is electrically connected to described controller.
As further improvement, the utility model also comprises spray equipment, and the gauge tap of spray equipment is electrically connected to described controller.
Preferably, described gauge tap is magnetic valve.
As a kind of preferred embodiment, described sensor is multiple, and divide the diverse location being located at described ammonia refrigeration system, each described sensor is provided with correspondence and is electrically connected with indicator lamp, and this indicator lamp is arranged on described controller.
As a kind of preferred embodiment, described exhaust fan is also provided with hand switch, hand switch is arranged on described outdoor.
As a kind of preferred embodiment, described controller is PLC.
After adopting the technical solution of the utility model, coordinated signals is realized by controller, whether sensor has ammonia to reveal in order to detect in ammonia refrigeration system, and detection signal is driven to alarm, during the signal revealed when there being ammonia, alarm receives alarm signal and reports to the police, simultaneously alarm by signal transmission to controller, controller sends instruction to refrigeration compressor and exhaust fan, control refrigeration compressor and close stopping refrigeration, the automatic switch controlling exhaust fan is opened, by ammonia dispatch to outdoor.So, the utility model controller is by the signal of existing acoustic-optic alarm, realize the automatic control to exhaust fan and refrigeration compressor, exhaust fan is opened without the need to manually going, NH_3 leakage can be processed more quickly, after can avoiding NH_3 leakage, refrigeration compressor works on simultaneously, avoids the waste of the energy.

Detailed description of the invention
In order to explain the technical solution of the utility model further, be described in detail below in conjunction with accompanying drawing.
With reference to Fig. 1, the emergent electrical control gear of refrigeration plant NH_3 leakage warning, comprise ammonia refrigeration system disposed in the interior, in order to monitor NH_3 leakage and the acoustic-optic alarm 20 of reporting to the police and the exhaust fan 40 in order to ammonia to be drained into outdoor, refrigeration compressor 10 is provided with in ammonia refrigeration system, acoustic-optic alarm 20 comprises the sensor 21 of alarm 22 and the setting of corresponding ammonia refrigeration system, these are existing introduction in the prior art, is no longer described in detail here.
The utility model also comprises controller 30, and described acoustic-optic alarm 20 and described refrigeration compressor 10 are all electrically connected to described controller 30, and described exhaust fan 40 is provided with automatic switch 41, and this automatic switch 41 is electrically connected to described controller 30.Specifically sensor 21 is arranged on the position that ammonia leakage comparatively may occur of ammonia refrigeration system, sensor 21 is electrically connected to alarm 22, alarm 22 is electrically connected to controller 30, controller 30 is arranged in control room, when there being NH_3 leakage to occur, sensor 21 detects the signal of NH_3 leakage, and is reported to the police to alarm 22 by signal transmission, alarm 22 is by signal transmission to controller 30 simultaneously, is controlled by controller 30 pairs of exhaust fans 40 and refrigeration compressor 10.
