Full-intelligent water draining facility

Abstract

The invention discloses a full-intelligent water draining facility, which consists of an on-site mechanical water draining device, an on-site monitor with a window, and a backstage centralized monitoring system, and is characterized in that improvement measures that a liquid inlet pipe connected with a T-type filter on the upper part of a buffer tank forms an included angle of 8 degree with the horizontal, the T-type filter and the buffer tank are wound with heating coils and the like are taken on the on-site mechanical water draining device; a main control panel circuit of the on-site monitor with the window comprises a power module, a 16-bit microprocessor chip, a universal serial bus (USB) interface circuit, an indicator light, a button and the like; and the backstage centralized monitoring system comprises an active (passive) RS-485 optoelectronic isolation repeater, an industrial grade four-channel RS485 intelligent expander, an active industrial grade RS-232-RS485 bidirectional converter, an industrial personal computer, water draining machine monitoring software and the like. The full-intelligent water draining facility integrates the advantages of the mechanical water draining device and an advanced electronic information technology, and realizes the automation in a tank station of a petrochemical system intelligently, safely and reliably.

Description

technical field [0001] The invention relates to an intelligent water cutting facility, in particular to a fully intelligent water cutting facility composed of a plurality of on-site mechanical water cutting devices combined with on-site monitoring and background centralized monitoring systems. Background technique [0002] At present, mechanical water cutters are generally used in petrochemical system oil tanks and chemical product pressure storage tanks. The working principle is to use the difference in buoyancy of the floating ball due to the difference in density between oil and water (Archimedes principle) and the principle of leverage to control the valve. The opening and closing of the oil tank cuts the water. However, the existing technology still has certain shortcomings in practice, mainly including: ① water cannot be cut normally in heavy oil, because the density difference between heavy oil and water is very small, and the float cannot be accurately distinguished;...

AI Technical Summary

Problems solved by technology

However, the existing technology still has certain shortcomings in practice, mainly including: ① water cannot be cut normally in heavy oil, because the density difference between heavy oil and water is very small, and the float cannot be accurately distinguished; Mechanisms such as floating balls and levers are easy to be adhered by oil products, and the water will carry oil; ③The dehydration part of the water cutter adopts a mechanical seal such as a valve core, which is prone to leakage accidents; A lot of deposited dirt needs to be cleaned regularly; ⑤The upper and lower covers of this kind of water cutting device are easily leaked due to the flange clamp gasket connection, and it is very inconvenient to overhaul and remove the cover, which is time-consuming and laborious; ⑥Its working status cannot be remotely controlled. It cannot meet the development needs of centralized monitoring in tank farms in the petrochemical industry
