The device comprises a mercaptan removing tail gas pipeline, a tail gas liquid separating tank, a liquid-free tail gas pipeline, a smoke mixing chamber and a chimney which are sequentially communicated with one another, wherein the inlet and outlet of the mercaptan removing tail gas pipeline are respectively communicated with the exhaust port of liquefied gas mercaptan removing equipment and the gas inlet of the tail gas liquid separating tank; the exhaust port of the tail gas liquid separating tank is communicated with the gas inlet of the smoke mixing chamber through the liquid-free tail gas pipeline; and the outlet of the smoke mixing chamber is communicated with the inlet of the chimney.
Description
Technical field
The utility model relates to the vent gas treatment technical field of petrochemical industry, relates in particular to a kind of liquid gas sweetening exhaust gas processing device.
Background technology
At petrochemical industry, the raw material that use when carrying out the liquefied gas aromatization in the isomerization workshop generally is the liquefied gas of coming from the catalysis workshop, and the sulphur content in the liquefied gas is inorganic sulfur and organic sulfur.Inorganic sulfur is hydrogen sulfide; Organic sulfur is mainly methyl mercaptan, ethyl mercaptan, also has a spot of DMDS, diethyl two sulphur, Methylethyl two sulphur, propanethiol, methyl sulfide, cos etc.Inorganic sulfur is washed by amine and is easy to remove, and the mercaptan in the organic sulfur then removes by the sodium hydroxide alkali wash-out.Disulphide, methyl sulfide, cos are washed or alkali cleaning all is difficult to remove by amine no matter be.Removal of mercaptans is exactly the technology that the mercaptan in the liquefied gas is removed, and this is that the difficult point of desulfurization also is emphasis.The tail gas of liquid gas sweetening contains a large amount of oxygen and peculiar smell, prior art be with exhaust emissions to atmosphere, so not only polluted atmosphere, but also caused the waste of calorific value.
The utility model content
Technical problem to be solved in the utility model is: at the deficiency that prior art exists, provide a kind of and reduce atmosphere pollution, rationally utilize the liquid gas sweetening exhaust gas processing device of exhaust combustion calorific value.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The liquid gas sweetening exhaust gas processing device, comprise that removal of mercaptans exhaust pipe, tail gas that order is communicated with divide flow container, take off liquid exhaust pipe, flue gas mixing-chamber and chimney, the import of described removal of mercaptans exhaust pipe and outlet are communicated with the air inlet that exhaust outlet and the tail gas of liquid gas sweetening device divide flow container respectively, tail gas divides the exhaust outlet of flow container to be communicated with the air inlet of described flue gas mixing-chamber by taking off the liquid exhaust pipe, and the outlet of described flue gas mixing-chamber and the import of described chimney are communicated with.
As a kind of scheme, the outlet of described removal of mercaptans exhaust pipe is communicated with the air inlet at described tail gas separatory pot sidewall middle part.
As a kind of scheme, described import of taking off the liquid exhaust pipe is communicated with the exhaust outlet of described tail gas separatory tank top.
As a kind of scheme, described outlet of taking off the liquid exhaust pipe is communicated with the air inlet at described flue gas mixing-chamber top.
As a kind of further scheme, described flue gas mixing-chamber is the flue gas mixing duct of horizontally set.
As a kind of further scheme, described flue gas mixing duct is obliquely installed, and the outlet of described flue gas mixing duct is higher than the import of described flue gas mixing duct.
As a kind of further scheme, described flue gas mixing duct and horizontal slanted angle are the 5-10 degree.
As a kind of scheme, the import of described chimney is 0.2-0.5 rice apart from the height on ground.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
The utility model is provided with tail gas and divides flow container, flue gas mixing-chamber and chimney, the sulfur-bearing tail gas that comes from the liquid gas sweetening device divides flow container to take off liquid through tail gas, prevented that like this liquid from entering chimney, the water droplet that mixes in the spark that has produced when effectively having stopped gas combustion has increased safety coefficient.Sulfur-bearing tail gas and high-temperature flue gas produce chemical reaction, not only protect environment also to increase calorific value.Sulfur-bearing tail gas fully mixes in flue gas mixing-chamber with high-temperature flue gas, has improved the efficiency of combustion in chimney.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Among the figure: 1. removal of mercaptans exhaust pipe, 2. tail gas divides flow container, 21. tail gas separatory canister incoming gas mouths, 22. tail gas divide the flow container exhaust outlet, 3. take off the liquid exhaust pipe, 4. flue gas mixing-chamber, 41. flue gas mixing-chamber air inlets, 5. chimney, 51. chimney imports.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, the liquid gas sweetening exhaust gas processing device, comprise that removal of mercaptans exhaust pipe 1, the tail gas that order is communicated with divides flow container 2, takes off liquid exhaust pipe 3, flue gas mixing-chamber 4 and chimney 5, the import of removal of mercaptans exhaust pipe 1 and outlet are communicated with exhaust outlet and the tail gas separatory canister incoming gas mouth 21 of liquid gas sweetening device respectively, tail gas divides flow container exhaust outlet 22 to be communicated with flue gas mixing-chamber air inlet 41 by taking off liquid exhaust pipe 3, and the outlet of flue gas mixing-chamber and chimney import 51 are communicated with.
The outlet of removal of mercaptans exhaust pipe is communicated with the tail gas separatory canister incoming gas mouth 21 at tail gas separatory pot sidewall middle part.
The import of taking off the liquid exhaust pipe divides flow container exhaust outlet 22 to be communicated with the tail gas of tail gas separatory tank top.
The outlet of taking off the liquid exhaust pipe is communicated with the flue gas mixing-chamber air inlet 41 at flue gas mixing-chamber 4 tops.
Flue gas mixing-chamber 4 is the flue gas mixing duct of horizontally set.The flue gas mixing duct is obliquely installed, and the outlet of flue gas mixing duct is higher than the import of flue gas mixing duct.Flue gas mixing duct and horizontal slanted angle are the 5-10 degree.
In the utility model when work,, from the liquid gas sweetening device and the sulfur-bearing tail gas that comes divides flow container to take off liquid through tail gas, entering flue gas mixing-chamber 4 then mixes with high-temperature flue gas, enters the chimney burning via chimney import 51 then.
