The invention provides a high-temperature-resistant anti-corrosion rotational flow shear type gas-liquid separator. The gas-liquid separator comprises first rotational flow shearing type separation standard module assemblies or second rotational flow shearing type separation standard module assemblies, each first rotational flow shearing type separation standard module assembly comprises a first tray body, a second tray body and a third tray body, or each second rotational flow shearing type separation standard module assembly comprises a first tray body, a second tray body, a third tray body,a fourth tray body and a fifth tray body; the first rotational flow shearing type separation standard module assemblies or the second rotational flow shearing type separation standard module assemblyassemblies are connected to a main shaft at intervals in the axial direction of the main shaft; when the rotating separator rotates at a high speed, liquid is continuously and circularly impacted bythe centrifugal force of the rotating separator and gas countercurrent, a solute and a solvent are separated efficiently and efficiently, the disc bodies, a main body and the main shaft of the gas-liquid separator are all made of corresponding anti-corrosion engineering materials, and the gas-liquid separator has the advantages of being good in anti-corrosion performance, easy to operate, low in energy consumption and the like, and is a novel efficient rotational flow shearing type gas-liquid separator suitable for resisting high temperature and preventing corrosion of various acid types.

Description

Technical field [0001] The invention relates to the technical field of gas-liquid separators, in particular to a high-temperature and corrosion-resistant cyclone shear type gas-liquid separator. Background technique [0002] The basic principle of supergravity engineering technology is to use the unique flow behavior of the multiphase flow system under supergravity conditions to strengthen the relative speed and mutual contact between phases. Among them, supergravity rotation generates strong centrifugal force, and the liquid is torn into Small liquid droplets, liquid films and liquid filaments flow outwards at high speed, generating a large amount of rapidly renewed surface area, thereby realizing efficient mass and heat transfer processes and chemical reaction processes. The supergravity separation technology is a new technology that strengthens the multiphase flow transfer and reaction process. The centrifugal force field is used for phase separation.

Problems solved by technology

However, at present, the main body of the gas-liquid separator and the internal components of the separator usually have three obvious defects, which greatly reduce the application effect: the first is the large number of moving plates, resulting in high energy consumption and low separation efficiency, and the parts are easily damaged ; Second, to make the separator, the main material used is not anti-corrosion material, which is basically economical 304 stainless steel. Due to the synthesis process of chemical industry, medicine and pesticide, it is synthesized in a strongly corrosive acidic medium, especially It is synthesized in hydrochloric acid medium, which seriously affects the service life of the 304 stainless steel gas-liquid separator. Using dual-phase steel and titanium to prepare the gas-liquid separator will increase the preparation cost sharply, and the user cannot afford it; thirdly, if Among the production materials of the swirl shear separation component (or other parts inside the main body of the separator), if corrosion-resistant glass fiber reinforced plastics are used for corrosion protection, high-temperature epoxy resin at 150-280 ° C is used for corrosion protection. Practice has proved that due to the high speed of the gas-liquid separator , large temperature difference and large pressure difference, it is very easy to cause local peeling and peeling of the anti-corrosion layer, and then cause serious internal corrosion and strength decline, and the equipment is paralyzed
