Drawings
FIG. 1 is a schematic structural diagram of a vehicle-mounted oil gas detector provided by the invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
As shown in fig. 1, the vehicle-mounted oil gas detector provided by the invention comprises a tank body 1, a filter 2, a drain valve 3, a sampler 4, an emptying regulating valve 5, an analyzer 6, a first exhaust pipe 7 and a second exhaust pipe 8;
the air outlet end of the tank body 1 is connected with the filter 2, and the air outlet end is provided with a valve; the air outlet end of the filter 2 is connected with a sampler 4; the drain valve 3 is arranged at the drain end of the filter 2;
one air outlet end of the sampler 4 is connected with an emptying regulating valve 5; the air outlet end of the air release regulating valve 5 is connected with a first exhaust pipe 7;
the other air outlet end of the sampler 4 is connected with the air inlet end of the analyzer 6; the gas outlet end of the analyzer 6 is connected with a second gas exhaust pipe 8.
In an alternative embodiment, the first exhaust pipe 7 and the second exhaust pipe 8 have a diameter of 6 mm.
In an alternative embodiment, the sample tube tubing between the canister 1, filter 2, drain valve 3, sampler 4, vent valve 5 and analyzer 6 is 8mm in diameter and employs a 6mm ferrule interface.
According to the invention, online monitoring of combustible gas and oxygen is realized, safety and reliability of cleaning work are ensured, analyzed sample gas is directly discharged to the atmosphere (through the first exhaust pipe 7 and the second exhaust pipe 8), condensate is periodically discharged (through the drain valve 3), and the drying agent is periodically replaced.
According to the invention, the system comprises a gas detector, a pretreatment device and the like, so that online measurement is completed, and continuous and uninterrupted data monitoring is ensured; the sample gas is extracted to the analysis cabinet by a vacuum air pump through the sampling probe and the middle sampling tube.
In an alternative embodiment, the analyzer 6 is equipped with a communication interface; the analyzer 6 is connected with a computer in wireless/wired communication, or the analyzer 6 is connected with a DCS central control system in communication through quasi-analog signals.
The vehicle-mounted oil gas monitor supports the various communication modes, can not only ensure the safety monitoring requirement of the operation of internal facilities of enterprises, but also ensure the supervision and management of field equipment by a central control department, and really realize multi-party benefit of one-time investment.
The manual operation mode of the invention is as follows: a 220V AC power supply (needing a safe grounding wire) is connected to the equipment, one end of a sample gas tube is connected into the tank body 1, and the other end is connected to an analyzer 6; after the pipelines are connected, a system power supply button is started, the combustible gas and the oxygen detector are started at the moment, then an air pump button is started, the sample gas is pumped out through the suction force of an air pump and sent into a sampler 4 after being pretreated, and the sample gas is finally diffused to the atmosphere.
Wherein, the remote control mode is as follows: after the analyzer 6 is powered on, an application program is started at a mobile phone end, a program starting button is clicked to start running the system, and monitoring data of combustible gas are displayed in real time.
In the implementation process of the scheme, as the breaking time of the outlet switch is extremely short, the priority of the current change threshold is put at the head in consideration of the reliability of data, and the current change threshold is responded to immediately. In addition, the method is influenced by objective factors such as the self condition of the base station, weather and the like, and information loss caused by conditions such as large wireless signal fluctuation and unexpected communication interruption is avoided. The FTU sends the telemetry current value to the master station every 10 seconds until the master station system acknowledges positively. If the telemetering mutation occurs in the signal fluctuation period, the mutation before the communication channel is interrupted and the last telemetering mutation in the interruption period can be recorded and sent, the accidental loss of the telemetering current value can be effectively avoided, and the reliability of the equipment is improved.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
