Concentration oil gas is imported in absorption tower and is separated.When in use, the utility model is broadly divided into absorption and desorption two states, In
Under adsorbed state, the mixed gas of oil gas and air imports tank interior through air inlet pipe, pass through sieve plate after with active carbon particle phase
Contact, for the utility model due to partition and the presence for being connected to notch, air-flow is moved upwardly by along snakelike circuitous path, is extended
The contacting travel of gas and active carbon particle, improves adsorption effect, clean air is finally expelled to outdoor by evacuated tube.To
After adsorption saturation, the utility model enters detachment status, and evacuated tube and air inlet pipe are closed, and vacuum-pumping tube is opened, in vacuum pump
Under effect, oil gas is detached from active carbon particle and moves downward, and the utility model is oily at this time due to being provided with check valve on short tube
Gas, to drain by shorter path from vacuum-pumping tube, can improve desorption effect by the directly lower row of short tube.To sum up institute
It states, the utility model has both excellent absorption and desorption performance, can be improved the rate of recovery of oil gas.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The center of a kind of adsorption/desorption device of petroleum vapor recovery as shown in Figure 1, including tank body 1,1 top of tank body is set
Set evacuated tube 2, the two sides setting air inlet pipe 3 and vacuum-pumping tube 4 of bottom.The utility model evacuated tube 2 is connected extraneous for being discharged
Clean air, air inlet pipe 3 connect the oil gas overfall of oil-stocking equipment for importing the gaseous mixture of oil gas and air into tank body 1
Body, vacuum-pumping tube 4 are connect with absorption tower by pipeline and vacuum pump and are imported in absorption tower for the high-concentration oil vapor after being desorbed
It is separated, this is same as the prior art, and details are not described herein again.
The utility model the difference is that, the upper and lower part in the tank body 1 is fixedly installed a transverse direction respectively
Sieve plate 5, the sieve plate 5 from top to bottom will successively be divided into discharge chamber 6, adsorbent chamber 7 and inlet chamber 8 inside tank body 1.The suction
Multiple lateral partitions 9 are from top to bottom evenly provided in attached chamber 7, as shown in Figure 1, the quantity of the partition 9 is generally three
, it is also feasible using more partitions 9 certainly.The inner wall of the partition 9 and tank body 1 is affixed, and the side of partition 9 with
A connection notch 10 is provided between the inner wall of tank body 1, the connection notch 10 on two adjacent partitions 9 is interlaced, such as
Shown in Fig. 1, on the right, then the corresponding connection of an intermediate partition 9 lacks the corresponding connection notch 10 of partition 9 of bottom
Mouth 10 is on the left side.That is, between partition 9 be connected to notch 10 7 common internal of adsorbent chamber constitute detour sorption channel,
When absorption, the mixed gas of oil gas and air moves upward along the channel.
