Abstract
The invention discloses a drainage process for suspension in a gas purification and absorption process. After a gas is washed by using liquid in a tower to generate suspension, nitrogen is inflated from a drainage pipe, the nitrogen ascends to displace the washed gas in the tower, and the suspension is drained from the bottom of the tower after the tower is full of the nitrogen and the pressure is raised. The nitrogen is adopted for pressure charge and drainage, namely the nitrogen is inflated into the tower at the same time of drainage, so that the liquid in the tower can be fully drained; and because the washed gas is displaced by the nitrogen, the gas does not escape during emptying, the drainage pipe has no residual liquid, and the probability of pipe blockage does not exist.
Description
Technical field
The present invention relates to the fluid-discharge technology of suspension liquid, particularly the fluid-discharge technology of suspension liquid in barium carbonate and the similar substance is produced in gas liquid reaction.
Background technology
The gas of sulfide hydrogen and carbonic acid gas and barium sulfide solution reaction are produced in the process of barium carbonate, and key link is the discharge opeing of falling tower discharging, and it is very important how resolving this Control essentials.If control badly, drain time is long, very easily causes hydrogen sulfide to be overflowed, and drain time is too short then may blocking pipe.
Summary of the invention
The fluid-discharge technology that the purpose of this invention is to provide suspension liquid in a kind of purification for gas absorption process, this technology can make the as safe as a house reliable of this process change, thereby produce safety and environmental protection benefit preferably.
The technical scheme that the present invention takes is:
The fluid-discharge technology of suspension liquid in the purification for gas absorption process after gas liquid scrubbing in tower generates suspension liquid, charges into nitrogen from Drainage pipe, and line replacement falls gas after the washing in the tower on the nitrogen, and suspension liquid is discharged at the bottom of tower.
Suspension liquid was drained only, avoided toxic gas excessively together to enter storage tank again with suspension liquid because of discharging.
This process using nitrogen pressurising discharge opeing, i.e. discharge opeing be inflated with nitrogen in tower simultaneously, and the interior liquid of tower is discharged fully, because washing back gas is by nitrogen replacement, so no longer overflow during emptying, and do not have remaining liquid in the liquid discharge pipe yet, the pipe possibility of jamming has not just existed yet.This is simple for process, only consumes a spot of nitrogen, just can make the fool proof of device operation control change, the effusion of particularly having stopped hydrogen sulfide, and the environmental benefit that brings is considerable.

Wherein: 1. washing tower, 2. nitrogen blanketing valve, 3. storage tank.
Embodiment
Embodiment 1
Contain barium carbonate discharge opeing process in the waste gas washing of hydrogen sulfide and carbonic acid gas:
Ta Neitong contains the waste gas of hydrogen sulfide and carbonic acid gas, treat that barium sulphide and the carbon dioxide reaction in the barium sulfide solution becomes barium carbonate fully in the tower, close exhaust gas inlet, the internally piloted valve of inflated with nitrogen is opened, after the nitrogen of tower inner accumulated displaces tower to hydrogen sulfide, close tower gas phase valve, tapping valve began to arrange the interior barium carbonate suspension liquid of tower to storage tank at the bottom of the continuation inflated with nitrogen was opened tower simultaneously in the tower, when in the tower during liquid emptying, nitrogen is full of whole tower, continue the end of logical nitrogen and overflow, show that the barium carbonate suspension liquid in the liquid discharge pipe does not exist yet, avoided raffinate to amass precipitation blocking pipe in pipe to nitrogen from liquid discharge pipe.Then add barium sulfide solution in tower, each valve reset begins new operation.
Claims (1)
1. the fluid-discharge technology of suspension liquid in the purification for gas absorption process, it is characterized in that, in tower, behind the liquid scrubbing generation suspension liquid, charge into nitrogen from Drainage pipe at gas, line replacement falls gas after the washing in the tower on the nitrogen, and suspension liquid is discharged at the bottom of tower.
