Description

Technical Field

[0001] The present invention relates to the technical field of oil-water separation, in particular to an integrated oil-water separation device using a floating ball. Background Art

[0002] Oil-water separator is used to separate impurities such as condensed water and oil in compressed air.

[0003] The known oil-water separation methods mainly include gravity separation, centrifugal separation, electrical separation, adsorption separation, flotation separation, etc.

[0004] Gravity separation is a typical primary treatment method, utilizing the density difference and immiscibility of oil and water to separate oil droplets, suspended solids, and water in either a static or flowing state. Oil droplets dispersed in water slowly rise and stratify under buoyancy, with the rate of their ascent dependent on particle size, the density difference between oil and water, the flow state, and the viscosity of the fluid. Gravity separation is used in most oil-water separators, but its primary challenge is separation efficiency, and the most significant factor influencing this efficiency is separation time, or residence time. A secondary factor is the inlet flow rate of the mixture, while the common solution is to increase the inlet size and thus the residence space, which has certain limitations and is difficult to meet demand.

[0005] Traditional oil floating collection devices can only collect floating oil, while clean water requires additional devices and outlets. Moreover, if the oil outlet pipe of the oil floating device is U-shaped, it will cause excess oil in the pipe or no oil can be discharged.

[0006] Traditional filter element coalescing devices only increase the aggregation of oil droplets and are not used in conjunction with separation filter element coalescing devices. Furthermore, coalescing filter elements are generally used in vertical separators because water enters the filter element from the bottom and then drains out from the bottom, leaving the oil floating at the top of the separator water level. Therefore, traditional filter element coalescing devices have a single function, are costly, and are rarely used.

[0007] In order to overcome the above problems, we designed an integrated oil-water separation equipment using a floating ball. Summary of the Invention

[0036] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific operation is as follows:

[0037] During use, the oil-water mixture enters the separation box 100 through the water inlet pipe 101, and the baffle 103 reduces the water inlet flow rate. The oil-water mixture first enters the slag removal area and removes the waste slag through the slag removal basket 104. After the preliminary treatment, the oil-water mixture enters the holes at the bottom of the slag removal basket and encounters the arc-shaped flow-blocking bend 105. The oil-water mixture slowly flows to both sides of the flow-blocking bend 105 and enters the filler coalescing basket 106. After the dispersed oil droplets are initially coalesced, it flows into the first separation area and passes through the corrugated plate 108 for further separation of oil and water. After the water level rises, under the action of the fan 109, the floating oil on the top of the water flow passes through the concave inclined plate 107 and its own concave oil storage tank and enters the oil outlet valve 110 for rough separation. After passing through the partition, it will gather under the partition. At this time, the flow rate of water is basically not flowing and the water The water level continues to rise, and when it reaches the height of the water inlet at the bottom of the shell 301 in the filter element coalescing mechanism 300, it enters the shell 301 and coalesces the oil droplets again. The setting of the separation filter element 302 will cause the clean water to gather at the bottom of the shell 301, and the floating oil to gather above the separation filter element 302. The skimming fan 304 and the oil-absorbing sponge 305 can further accelerate the separation of oil and water, thereby reducing the oil-water separation time. At this time, the floating oil collection mechanism 400 continues to rise as the water level rises, and the spring 407 at the bottom of the float 408 will pull open the bottom pull ring switch 406. At this time, the clean water at the bottom enters the water storage tank 200 from the water outlet tube 405, and the floating oil on the top is collected by the oil inlet mesh sleeve 402 in the center of the floating oil collection mechanism 400 and enters the elastic telescopic oil outlet pipe 401.
