Abstract
The utility model provides a gas-liquid separator for tail gas of a sulfuric acid absorption tower, which belongs to the field of industrial tail gas treatment and mainly comprises a tank and an internal baffle plate. A gas inlet is arranged on the right upper portion of the tank and connected with an exhaust pipe of the absorption tower, a gas outlet is arranged at the position of the central line at the top end of the tank and connected with a smoke pipe, a liquid outlet is arranged at the position of the central line at the bottom of the tank, the baffle plate is a stainless steel plate fixed in the direction perpendicular to a gas inlet direction, the upper end of the baffle plate is positioned on the right side of the central line of the tank, and the overall length of the baffle plate extends to the lower side of the gas inlet in the horizontal direction. The gas-liquid separator has the advantages that by the aid of the technical scheme, acid drops in the tail gas of the absorption tower can be separated from gas, on one hand, more environmental protection and safety can be achieved, and on the other hand, sulfuric acid is recycled and waste is reduced.
Description
Technical field
The utility model belongs to the industrial waste gas process field, especially relates to a kind of sulfuric acid absorption tower tail gas gas-liquid separator.
Background technology
In the sulphuric acid process, having one to absorb link, mainly is in the absorption tower, to carry out, and sprays dilute sulfuric acid from top, absorption tower, and the bottom feeds the SO that the Molten sulphur burning produces
3, SO
2, O
2, N
2, main component is SO
3, the moisture absorption SO in the dilute sulfuric acid
3, produce sulfuric acid, through this effect, obtain the sulfuric acid product that concentration improves, unabsorbed tail gas is discharged via chimney.The problem of existence is to carry acid secretly through regular meeting in the tail gas to drip and other unabsorbed gases, causes environmental pollution so on the one hand, and is of long duration on the other hand, can cause corrosion to people and building on every side.
Summary of the invention
The technical problem that the utility model will solve provides a kind of simple in structure, easy to operate sulfuric acid absorption tower tail gas gas-liquid separator.
The technical scheme of the utility model is: a kind of sulfuric acid absorption tower tail gas gas-liquid separator, mainly to form by tank body and inner baffle plate, and said tank body right upper portion has air inlet, links to each other with the discharge duct on absorption tower; The top position of center line has the gas outlet, links to each other with chimney; Bottom centre's line position has leakage fluid dram; Said baffle plate is a corrosion resistant plate, is fixed in the direction vertical with airintake direction, and the upper end is in tank body center line right side, and entire length reaches below the air inlet horizontal direction.
The said tank body outside is arranged with two legs.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, can realize that the acid of carrying secretly in the tail gas from absorption tower drips separated from the gasly, Environmental Safety has more been realized the sulfuric acid recovery on the other hand on the one hand, has reduced waste.
Description of drawings
Fig. 1 is the sketch map of the utility model
Among the figure:
1, air inlet 2, gas outlet 3, leakage fluid dram
4, baffle plate 5, tank body 6, leg
The specific embodiment
Like Fig. 1, this uses shown in the novel sketch map, the utility model mainly is made up of tank body 5 and inner baffle plate 4, said tank body right upper portion has air inlet 1, links to each other with the discharge duct on absorption tower; The top position of center line has gas outlet 2, links to each other with chimney; Bottom centre's line position has leakage fluid dram 3; Said baffle plate 4 is a corrosion resistant plate, is fixed in the direction vertical with airintake direction, and the upper end is in tank body 5 center line right sides, and entire length reaches below air inlet 1 horizontal direction.
The said tank body outside is arranged with two legs 6.
The course of work of this instance: the gas in the discharge duct on absorption tower mainly comprises SO
3, SO
2, O
2, N
2, main component is SO
3, carrying acid secretly and dripping in the tank body 5 by air inlet 1 entering the utility model gas-liquid separator, blocked by baffle plate 4 in vertical direction; Because of liquid is heavy than gas, so the drop gravitate is separated from the gas; Drippage gets off; Gather tank body 5 bottoms, gas is then discharged by the gas outlet 2 on tank body 5 tops, gets into chimney and enters atmosphere.
The leg 6 of tank base can make this gas-liquid separator stably stand on ground.
After using a period of time, the leakage fluid dram 3 of tank body 5 bottoms is opened, the sulfuric acid that reclaims is taken away again utilized.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
Claims (2)
1. sulfuric acid absorption tower tail gas gas-liquid separator is characterized in that: be made up of tank body and inner baffle plate, said tank body right upper portion has air inlet, links to each other with the discharge duct on absorption tower; The top position of center line has the gas outlet, links to each other with chimney; Bottom centre's line position has leakage fluid dram; Said baffle plate is a corrosion resistant plate, is fixed in the direction vertical with airintake direction, and the upper end is in tank body center line right side, and entire length reaches below the air inlet horizontal direction.
