Abstract
The utility model provides a kind of petroleum vapor recovery pretreatment unit, is the assembly of vertical tank body and horizontal tank body unicom, and there is the external shell side wall of vertical tank oil and gas import, top there is clean gas outlet, side wall separately to have phegma entrance；There is spray equipment, lower section to have adsorption stuffing, phegma entrance and spray equipment unicom, phegma entrance can be with spray equipment unicom above vertical tank interior.The utility model can absorb oil gas or organic exhaust gas well, while can recycle wherein useful component element sulphur, and the cold of cooling condensation can recycle, and reduce energy consumption.
Description
Technical field
The utility model is related to oil gas or the preconditioning techniques of exhaust gas.
Background technology
The pretreatment measure of oil gas or organic exhaust gas has spray-absorption, adsorption tower adsorption-desorption, bio-absorbable degrade, is cold
Lime set etc., some methods are used alone, and combine a little use, and the effect of processing respectively has the similarities and differences.
Invention content
Purpose of utility model：Offer one kind being readily able to liquefied ingredient and detaches in advance, and the oil gas with desulfurizing function returns
Receive pretreatment tank.
Technical solution：
Petroleum vapor recovery pretreatment unit provided by the utility model is the assembly of vertical tank body and horizontal tank body unicom, is stood
Formula tank body is located at the top of horizontal tank body.There is the external shell side wall of vertical tank oil and gas import, top to have clean gas outlet, side wall
Separately there is phegma entrance；There is spray equipment, lower section there is adsorption stuffing, exhaust gas inlet to be filled out with absorption above vertical tank interior
Expect unicom.Phegma entrance and spray equipment unicom.
It is provided with condensing unit in adsorption stuffing or on the external shell side wall of vertical tank so that most of organic matter in oil gas
Matter cooling liquefaction.The solution of formation enters in horizontal tank body, and cooling device is provided in horizontal tank body, is had in horizontal tank body case
There are cooling liquid outlet, liquid storage floss hole that can separately have buck entrance（For the hydrogen sulfide in addition buck, with oil gas, titanium dioxide
The ingredients such as sulphur, sulfur trioxide neutralize, and remove the element sulphur in oil gas）.
There is the pipeline of unicom between cooling liquid outlet and phegma entrance, there is pumping installations on the pipeline, provide molten
The power of liquid conveying reflux.
The phegma formed after buck desulfurization is added in buck entrance, upper due to PH when being used further to spray-absorption oil gas
It rises, it is easier to absorb the oil gas of sulfur-bearing, harmful components are less in the purification gas of direct emission.
When utility model works, the course of work with following sequences：
1）Oil gas is absorbed, by filling adsorption when passing through filler from oil and gas import by the spray liquid of spray equipment；
2）Most of organic substance cooling liquefaction forms waste liquid and enters horizontal tank body in oil gas, the low concentration gas of generation or
Person's purified gas is discharged from clean gas outlet.
3）Waste liquid is further cooled in horizontal tank body, is then pumped to phegma entrance from cooling liquid outlet.
4）Phegma sprays out from spray equipment, absorbs the oil gas subsequently entered, carries out next cyclic process.
In the course of work 2）-3）Between, in the buck entrance of horizontal tank be added buck after, in waste liquid hydrogen sulfide, two
Sulfur oxide, sulfur trioxide etc. play neutralization reaction, form heavier brine and are discharged from pot bottom.
The utility model has following multiple functions：
Absorption function：The low-temperature solvent of liquid phase absorbs the dissolvable composition in oil gas；
Horizontal tank refrigerating function so that phegma temperature reduces very much；
Vertical tank returns cold function：Phegma sprays the oil gas precooling so that coming in, and reduces the consumption cold of later stage cooling；
Two kinds of tank bodies so that the pressure of oil gas is buffered, and spray can go out fog；
It, can be with hydrogen sulfide, sulfur dioxide, the sulfur trioxide etc. in waste liquid after buck is added in the buck entrance of horizontal tank
Neutralization reaction is played, realizes the function of desulfurization.
Advantageous effect：
The utility model can absorb oil gas or organic exhaust gas well, while can recycle wherein useful component sulphur member
The cold of element, cooling condensation can recycle, and reduce energy consumption.Cooling is conducive to neutralize the progress of exothermic reaction, contains
The absorbability that the withdrawing fluid of lye absorbs oil gas is improved, and is polluted in the purified gas of discharge less.

Specific implementation mode
Petroleum vapor recovery pretreatment unit as shown in Figure 1 is the assembly of vertical tank body and horizontal tank body unicom, vertical tank
Body is located at the top of horizontal tank body；There is the external shell side wall of vertical tank oil and gas import, top there is clean gas outlet, side wall separately to have
Phegma entrance；There is spray equipment, lower section to have adsorption stuffing above vertical tank interior；Condensation is provided in adsorption stuffing
Device so that most of organic substance cooling liquefaction, the solution of formation enter in horizontal tank body in oil gas.
Be provided with cooling device in horizontal tank body, there is cooling liquid outlet in horizontal tank body case, cooling liquid outlet with return
There is the pipeline of unicom between flow liquid entrance, there is pumping installations, phegma entrance and spray equipment unicom on the pipeline.
Also there is horizontal tank body buck to enter confession inflow lye, remove to neutralize hydrogen sulfide, the sulfur dioxide or three in waste liquid
Sulfur oxide.
