Embodiment 1

[0081] exist figure 1 In this process, the reactor head is not disassembled, and petroleum sulfonate raw material oil is used, and the raw material oil is introduced into the cleaning liquid preparation tank 110, poured into the cleaning liquid circulation tank 120 through the cleaning liquid preparation pump 170, and the cleaning liquid circulation pump 150 is started , send the raw material oil to the gas-liquid separator 300 to be cleaned, and connect the gas-liquid separator 300 to the inlet flow of the cleaning liquid circulation pump 150 . Use the first liquid distributor 130 connected to the gas path of the sulfonation reactor 200 and the second liquid distributor 140 on the oil path, gradually open the gas path valve and the oil path valve of the head of the sulfonation reactor 200, and simultaneously Turn off the valve of the cleaning liquid circulating pump 150 to remove the gas-liquid separator 300, through the compressed air inlet 131 of the first liquid distributo...

Embodiment 2

[0083] exist figure 1 , do not disassemble the reactor head, use 10% dilute lye at 60°C, introduce 10% dilute lye into the cleaning solution preparation tank, pour it into the cleaning solution circulation tank 120 through the cleaning solution preparation pump 170, and start the cleaning solution Circulation pump 150 sends the 10% dilute lye to the gas-liquid separator 300 to be cleaned, and opens the gas-liquid separator 300 to the cleaning liquid circulation pump 150 inlet process. Use the first liquid distributor 130 connected to the gas path of the sulfonation reactor 200 and the second liquid distributor 140 on the oil path, gradually open the gas path and oil path valves at the head of the sulfonation reactor 200, and simultaneously turn off the small cleaning The liquid circulation pump 150 goes to the valve of the gas-liquid separator 300, through the compressed air inlet 131 of the first liquid distributor 130 and the compressed air inlet 141 of the second liquid dis...

Abstract

The invention provides an on-line cleaning device and method of a multitube membrane-type sulfonation reactor. The on-line cleaning device of the multitube membrane-type sulfonation reactor is connected to a sulfonation reactor and a gas-liquid separator, the sulfonation reactor comprises a gas path inlet and an oil path inlet, the on-line cleaning device comprises a cleaning liquid preparation tank, a cleaning liquid circulation tank, a first liquid distributor, a second liquid distributor and a cleaning liquid circulating pump, the first liquid distributor is connected to the gas path inlet, the second liquid distributor is connected to the oil path inlet, and an outlet of the cleaning liquid circulating pump is respectively connected to an inlet of the cleaning liquid circulation tank, an inlet of the first liquid distributor, an inlet of the second liquid distributor and an inlet of the gas-liquid separator. The second liquid distributor is a spiral liquid distributor. When a cleaning liquid enters the sulfonation reactor through the second liquid distributor, a helical flow is formed. Through two-way cleaning of the oil path and the gas path, the helical flow is formed through the helical distributors so that cleaning effects are good.

Description

technical field [0001] The invention is applicable to the cleaning technical field of multi-tube sulfonation reactors, especially the technical field of cleaning petroleum sulfonate multi-tube sulfonation reactors, and specifically relates to an online cleaning of multi-tube membrane sulfonation reactors method. Background technique [0002] In view of the coking situation of multi-tube falling film sulfonation reactors, domestic and foreign manufacturers basically adopt off-line cleaning methods at present, and the cleaning effect is not good. Most of them need to disassemble the reactor parts and use raw material oil, hot water, hot alcohol or dilute alkali Simple cleaning of the tube bundle of the sulfonator with liquid, etc. Due to factors such as uneven distribution of cleaning liquid, no disturbance and low liquid flow rate, there are problems such as long cleaning time and incomplete cleaning. In addition, the cleaning liquid cannot be used multiple times, not only th...
