Embodiment 1

[0036] like figure 2 As shown, an online cleaning device for a trough-type liquid distributor is arranged above the trough-type liquid distributor on the packed bed at the top of the vacuum tower. The trough-type liquid distributor is provided with 21 secondary distribution tank 6. The online cleaning device includes: two flushing main pipes 3 and flushing branch pipes 4; the cleaning main pipe 3 is placed at the hanging beam position of the secondary distribution tank 6, which also serves as a support function, and the hanging beam is no longer installed separately to save investment. One end of the flushing main pipe 3 is connected to the nozzle 2 arranged on the tower wall, and the other end is welded to a support fixed on the inner side of the tower wall; lifting lugs 5 are welded on both sides of the flushing main pipe 3 for hoisting the secondary distribution tank.

[0037] One end of the flushing branch pipe 4 communicates with the flushing main pipe 3 , and the other...

Abstract

The invention relates to an online cleaning device and an online cleaning method for a trench type liquid distributor in the petrochemical engineering field. The cleaning device is arranged above the trench type liquid distributor and comprises main flushing pipes (3) and flushing branch pipes (4), wherein one ends of the main flushing pipes (3) are connected with pipe nozzles (2) arranged on the tower wall, and the other ends of the main flushing pipes (3) are fixedly connected with the tower wall; secondary distributing trenches (6) of the trench type liquid distributor are suspended on the main flushing pipes (3); one ends of the flushing branch pipes (4) are communicated with the main flushing pipes (3), and the other ends of the flushing branch pipes (4) stretch into the bottoms of the secondary distributing trenches (6). Flushing fluid enters the main flushing pipes (3) through the pipe nozzles, then enters the flushing branch pipes (4) and is finally sprayed out so as to flush the secondary distributing trenches (6). According to the device and the method, sediments produced by the trench type liquid distributor in use can be effectively cleaned, and the liquid distributing effect of the trench type liquid distributor can be improved, the production period of the device is prolonged and the good application prospect is achieved.

Description

technical field [0001] The invention relates to an internal component used in a fractionation tower in the field of petrochemical industry, and more particularly, to an online cleaning device and method for a trough-type liquid distributor. Background technique [0002] Column packing technology is a separation technology widely used in petroleum refining, petrochemical, coal chemical, food and pharmaceutical industries. The trough liquid distributor has the characteristics of uniform liquid distribution, high operating flexibility, and strong anti-clogging and anti-coking capabilities. It is widely used in packed fractionation towers. The development of its technology also promotes the progress and development of tower packing technology. [0003] In recent years, during the actual industrial application of packed fractionation towers, mechanical impurities, ash, sludge, rust, etc. in the distribution medium are often deposited in the secondary distribution groove of the tr...
