A large gas-liquid separator

Abstract

The invention discloses a large-scale gas-liquid separator, which comprises an outer shell with an upper head and a lower head, the upper head is provided with an air inlet, the lower head is provided with an exhaust port, a main The outer cylinder of the liquid port and the gravity settlement drain, the outer cylinder is provided with a middle cylinder and an inner cylinder, and the middle cylinder and the inner cylinder separate the interior of the outer cylinder into three independent chambers body, the cavity between the middle cylinder and the inner cylinder communicates with the air inlet and the gravity sedimentation drain, the inner cavity of the inner cylinder communicates with the exhaust port, and the cavity between the middle cylinder and the inner cylinder There are a plurality of cyclones arranged obliquely, and the upper and lower ends of the cyclones protrude and are arranged in the cavity between the middle cylinder and the outer cylinder. The invention has good separation effect of gas-liquid mixture and good continuous separation performance, and is especially suitable for gas-liquid separation with pressurized gas, large processing gas volume, low resistance and high separation efficiency.

Description

technical field [0001] The invention relates to chemical engineering heterogeneous phase separation equipment, in particular to a large gas-liquid separator. Background technique [0002] Gas-liquid separation is an important chemical unit operation, which can realize the recovery of materials and the purification of target substances. In the production or process of industries such as chemical industry, metallurgy, energy and environmental protection, it is necessary to separate the gas-liquid two-phase mixture. Usually, appropriate separation methods and equipment are used and a certain amount of material or energy is consumed to achieve the goal. The basic separation methods of gas-liquid separation include gravity sedimentation, collision separation, centrifugal separation, Venturi gas-liquid separation, electrostatic separation, etc., which are respectively applicable to different particle size ranges. Using different separation principles, the structure of the gas-li...

Problems solved by technology

Also, the separator is not suitable for a larger processing gas volume due to the large number of swirl tubes that need to be arranged. At the same time, the separator does not consider the cross-gas back-mixing problem at the bottom of multiple swirl tubes. In addition, the separator is provided with the first And the second two return pipes are also unreasonable, which is equivalent to a short circuit effect on the swirl pipe, so its separation efficiency is not high
