Embodiment Construction

[0017] For the aforementioned and other technical content, features and effects of the present invention, the following references are made in the appended figure 1 It will be apparent from the detailed description of the embodiments. The structural contents mentioned in the following embodiments are all based on the accompanying drawings of the description.

[0018] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0019] In the process of safe production, multiple dangerous points of ammonia leakage can often be identified, but according to our company's safety operation regulations and combined with the actual production in the workshop, there are two most important leakage dangerous points at this stage, so this application adopts Two sensors are used to monitor the two most important dangerous points, so as to ensure that when ammonia gas leaks, the dangerous points can be quickly located, thereby elimin...

Abstract

The invention discloses a major hazard source safety monitoring device which effectively solves the problem that in the prior art, emergency rescue personnel do not know the specific position where ammonia gas leakage occurs, and then rescue work of the emergency rescue personnel outside a production workshop is affected. The signal detection circuit transmits a signal detected by the ammonia gas sensor to the control processing circuit through the receiver and the amplifier, and the control processing circuit conducts the alarm circuit after the signal passes through the judger and transmits the signal to the monitoring center after the signal passes through the voltage stabilizer. A voltage stabilizing tube D1 is arranged in the signal detection circuit to detect whether the concentration in a storage workshop exceeds a standard value or not at the moment, and a judger and a triode Q5 are used in a control processing circuit to control conduction of a relay K1, so the working state of an ammonia compressor U2 is controlled; therefore, the ammonia compressor U2 can be immediately turned off when the concentration of ammonia gas in a production workshop exceeds the standard.

Description

technical field [0001] The invention relates to the field of monitoring and detection, in particular to a safety monitoring device for major danger sources. Background technique [0002] Ammonia gas is one of the major hazard sources. There are safety standards for the storage, transportation and use of ammonia gas. Correspondingly, a major hazard source safety monitoring system is also set up to detect the concentration in the air in the production workshop. , and when the ammonia concentration value represented by the detected signal exceeds the standard value, the sensor will issue a warning and send the signal to the monitoring center, and the emergency rescue personnel must turn off the ammonia compressor in time to prevent the ammonia compressor from leaking ammonia Still compressing more ammonia. [0003] In the prior art, generally only one ammonia gas sensor is installed to detect the ammonia gas concentration in the production workshop. However, there are many dan...
