On-line monitoring equipment for leakage of pipe flange and installation method

Abstract

The invention provides on-line monitoring equipment for leakage of a pipe flange. The on-line monitoring equipment is characterized by comprising a leakage chamber, a monitor and a sensor, wherein thesealing method of the leakage chamber is one of sealing or semi-sealing; the monitor comprises a signal processing and caching module, a main control module, a radio frequency transceiver module anda power module; the monitor is fixed on an outer wall of the leakage chamber; the sensor is connected with the signal processing and caching module; the signal processing and caching module is connected with the main control module; the radio frequency transceiver module is connected with the main control module; the power module is connected with the signal processing and caching module, the maincontrol module and the radio frequency transceiver module; and the sensor is connected to the monitor, is fixed at the bottom of the monitor and extends into the inside of the leakage chamber. The on-line monitoring equipment has the beneficial effects that the on-line monitoring equipment can be widely arranged and is low in price, convenient to install, safe, reliable, long in life and high inaccuracy.

Description

technical field [0001] The invention relates to the field of gas and oil leakage monitoring, in particular to an online monitoring device and installation method for pipeline flange leakage. Background technique [0002] Leakage of industrial gas and oil is an important problem in the process of factory operation. Leakage may endanger human safety and destroy the surrounding environment, that is, the ecological balance, causing serious loss of life and property. Due to the large range of industrial production equipment, seals are generally used in places that often need to be operated or disassembled. The tightness of the seal will be deteriorated due to the indirect or direct influence of various conditions. If a certain method or device cannot be used to monitor the leakage of gas or oil in time and take corresponding measures, the leakage will expand rapidly over time, endangering normal production and causing economic losses. [0003] Traditionally, flow method, infrar...

AI Technical Summary

Problems solved by technology

The tightness of the seal will be deteriorated due to the indirect or direct influence of various conditions

If a certain method or device cannot be used to monitor the leakage of gas or oil in time and take corresponding measures, the leakage will expand rapidly over time, endangering normal production and causing economic losses

[0003] Traditionally, flow method, infrared spectroscopy, manual inspection method, etc. are used for monitoring. These commonly used monitoring methods often consume a lot of manpower and time, and the monitoring accuracy and reliability are relatively low. For ul / min level The micro-leakage is often powerless

However, the existing fixed online monitoring systems often have the following disadvantages: (1) Complicated installation: general fixed monitoring equipment needs to use special gaskets or valves, and the on-site equipment needs to be rebuilt, which increases the difficulty of installation; (2) Expensive: Due to the complicated installation and increased cost of general fixed monitoring equipment, it often costs thousands of yuan, and it is difficult to spread widely

(3) No protective function: In the case of a large amount of equipment leakage, the general monitoring equipment cannot prevent the dripping and splashing of the leaked liquid, which poses a huge threat to the safety of personnel and equipment around the production equipment

(4) No passive function: general fixed monitoring equipment consumes a lot of power and requires wire arrangement or solar power supply, but for inaccessible points and other places where wires or solar power supply are not suitable, it causes a large At the same time, this also greatly increases the equipment cost and installation cost, which is not conducive to large-scale promotion
