Description
Technical field
The present invention relates to a kind of Self-Priming Gas-Liquid Reactor, belong to chemical industry, environmental protection equipment technical field.
Background technology
In industrial application, often need gas-liquid two-phase haptoreaction process, as absorb with liquid phase in the chemical field and captured gas in useful component, to produce product; Remove the harmful components in the discharging waste gas in the environmental protection field, make gas purification, in order to avoid atmosphere pollution.The equipment that is used for gas-liquid contact reaction is the most commonly used with tower equipment, as tray absorption columns, packed tower.In tower equipment, liquid from cat head along under column plate or the filler stream, gas and liquid step by step adverse current or and stream contact and finish reaction.Tower equipment has many shortcomings that are difficult to overcome: accurately control of the flow velocity needs of gas-liquid two-phase in (1) tower equipment, otherwise accidents such as liquid flooding or flooding appear easily.If the fluctuation of source of the gas tolerance is very big, then be difficult to find suitable operating condition.(2) if gas is unholiness, when wherein carrying impurity such as dust secretly, impurity is easy to assemble in column plate or filler, results in blockage.(3) tower gas liquid reaction system architecture complexity, liquid needs special conveying, metering and storage system; Gas then needs the equipment of blower fan or other form to deliver in the tower equipment.
The gas-liquid mixed method commonly used in water treatment field is aeration, and it is that the gas on the liquid level is introduced under the liquid to increase a kind of method of gas meltage in the liquid.For example, patent CN2337140Y discloses a kind of aerator of impeller under water, and it under water finishes aeration with air by hollow shaft and the venthole introducing that is arranged on the impeller shaft by driven by motor hollow shaft and impeller shaft and wheel rotation; Patent CN93212866.1 discloses a kind of deep aerating machine, it utilizes motor-driven screw-pushing type blade propeller to stir surface liquid, by stretch in the deep-layer liquid guide shell with deep-layer liquid rise to the surface and through the curved surfaces of diffusion tip to around diffusion, airborne oxygen is fully mixed, and airborne oxygen is fully contacted with liquid transfer in the liquid phase.Above-mentioned aerator is only introduced air in the water to increase dissolved oxygen, and the gas that can not be applied to specific components contacts with specific components liquid two and finishes the target chemical reaction.Similarly the aerator patent also has CN200420022996.8, CN93226779.3, CN98211685.3, CN200420039888.1, CN200420060716.2, CN200420082155.6, CN200520018460.3, CN200510055350.9, CN200710086448.X.
AGR (advanced solid/liquid/gas reactions device) mixer instance such as US4454077 very famous in gas-liquid mixed equipment are described, adopt the downward conveying impeller that is located in the hollow runner pipe so that cause a kind of pattern that circulates in the liquid of dress in blender.Because this liquid in the hollow runner pipe circulates downwards, upper entrance zone at runner pipe forms some eddy current, thereby produce a kind of swabbing action, this acts on from container and extracts gas in portion's gas compartment, and makes it to mix with downward circulation fluid by runner pipe.The effect of gas-liquid mixed largely is limited by the height that liquid level remains on the runner pipe over top in the practical operation, is higher or lower than this optimum height AGR blender all with cisco unity malfunction.For this reason at patent US5009816, US4919849, US5244603, US5004571, among the CN95105038.9 etc. the AGR blender has been carried out a large amount of improvement, but under the situation that liquid level changes in container, the efficient of bleeding from upper space still is subjected to very big influence, and gas only circulates in the upper space in container and the liquid.
Patent CN201101961Y discloses the solid stirred reactor of a kind of gas-liquid, rely on driven by motor hollow shaft, air distribution disk and paddle to rotate, but only realized reacting gas circulation in the gas compartment on tank body top and the jar in the reactant liquor, it is then inapplicable to need once contact to pass through the situation of reactant liquor for gas.This reactor does not have the automatic function air-breathing from the external world simultaneously.
Patent CN101293190A discloses a kind of self-suction type inner circulation overweight field gas-liquid reactor.Adopt gas to enter from the region trochanterica bottom, the mode that liquid enters from region trochanterica top, enter rotor and cause system's instability for preventing that a large amount of gases that contain in the rotor upper liquid from carrying secretly, on stator, set up guide shell to strengthen gas-liquid separation, and on reactor wall, be provided with baffle plate, but in a single day liquid level is lower than the guide shell upper edge in this reactor tank, and then rotor can't feed liquor, and reactor can't operate as normal.
