Abstract

The invention belongs to the technical field of separation, and relates to a coaxial separator. A rotational flow guide vane is arranged in a fluid inlet pipe, and the outlet of the fluid inlet pipe is provided with a separator rotary vane area; and between the fluid inlet pipe and a separator shell, the lower part is provided with a liquid rotational flow guide vane, a liquid outlet pipe and a U-shaped liquid air seal pipe, and the top part is provided with a defoaming layer and an exhaust pipe. The coaxial separator has significant effects, is suitable for fluid separation in small pipes, and is particularly suitable for an emergency diffusion pipe of a dry type gas tank.

Example Embodiment

[0011] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings:
[0012] A swirling guide vane 2 is installed in the fluid inlet pipe 1, and a separator rotary vane area 4 is installed at the outlet of the fluid inlet pipe 1. Between the fluid inlet pipe 1 and the separator housing 12, a liquid swirling guide vane 8 and a liquid outlet pipe are installed at the bottom 9 and a U-shaped liquid gas seal pipe 10, and a defoaming layer 6 and an exhaust pipe 7 are installed on the top.
[0013] When the fluids of the two media enter from the fluid inlet pipe 1 at the lower part of the equipment, they then pass through the swirl guide vane 2 for pre-rotation, so that the fluid rotates, and the rotating fluid enters the cyclone blade zone 4 through the narrow annular slit. During high-speed centrifugal separation, the liquid and gas are separated into the liquid separation zone 3, and then further separated by the liquid swirl guide vane 8, and the liquid then flows from the liquid collecting pipe 9 and then passes through the liquid seal 10 and overflows from the outflow port 11. The gas enters the gas collection area 5, and then passes through the gas-liquid defoaming layer 6 and then is sent out from the gas outlet 7.
[0014] The best installation method of the present invention is vertical installation.
[0015] The velocity of the fluid entering the fluid inlet pipe 1 shall not be less than 10m/s.
[0016] For example: the emergency relief pipe of our dry gas tank is usually designed from DN400 to DN500. Usually the pipe is not working. In the case of emergency relief, the pipe will usually be poured into the seal about 2 to 3 meters high from the piston oil ditch. Oil, when the piston runs beyond the emergency relief port, part of the sealing oil poured into the emergency relief pipe will return to the gas tank, while the other part of the sealing oil will be sprayed out from the emergency relief in the form of gas-liquid mixture with the gas. The gas flow rate of the emergency relief pipe is usually 18m/s~40m/s, which is very suitable for this coaxial gas-liquid separator. After passing through the coaxial gas-liquid separator, the expensive sealing oil is recovered, the pollution does not exist, the danger of topping the gas tank is eliminated, the safety of the gas tank is improved, and the operating flexibility is increased. At the same time, the gas tank The storage capacity can be increased by 5%. This effect is very impressive.
[0017] The invention has significant effects, is suitable for small pipeline fluid separation, and is particularly suitable for emergency relief pipes of dry gas tanks.
