Description
Technical field
The utility model relates to the water injection vacuum pump that chemicals production equipment, particularly chlorine dioxide production are used.
Background technique
The production method of sodium chlorite mainly contains two kinds of electrolysis method and reduction methods, this project technique is reduction method, that is: sodium chlorate, sulfuric acid, sodium hydroxide (caustic soda), hydrogen peroxide (hydrogen peroxide) are raw materials, adopt the production technology of hydrogen peroxide (hydrogen peroxide) reduction.
Sodium chlorate solid is mixed with to saturated solution, in main generator (airtight negative pressure), adds sodium chlorate solution's (17%), sulfuric acid (98%) and hydrogen peroxide (27.5%) by process ratio, reaction generates chlorine dioxide.Chlorine dioxide is through passing through in pipeline suction tourie, and the concentration that aspiration procedure is constantly supplemented air reduction chlorine dioxide is less than 10%.
Water jet pump working principle, has the working medium water of certain pressure, to air chamber ejection at a high speed, the pressure energy of water is become to kinetic energy by nozzle, forms high-speed jet; Gas in air chamber is forced to carry with it by high-speed jet and is mixed, and forms gas-liquid mixed stream, enters diffusing tube, thereby air chamber pressure is reduced, form vacuum, in the extending section of diffusing tube, the kinetic energy of mixed jet changes pressure energy into, Speed Reduction pressure raises, and gas is further compressed, together with water outside excavationg pump, air-water separation in water tank, air release enters atmosphere, and water, by water pump cycling and reutilization, goes round and begins again and reaches the object vacuumizing.
At present traditional ejector vacuum pump adopts single nozzle structure, and waterpower skewness is poor with the mixed effect of pumped gas, affects vacuumizing effect, explosion chamber single stage compression, and the fluctuation of mixed gas velocity variations is larger, and pumping efficiency is low.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of effect of strengthening bleeding, and pumping efficiency is provided, simultaneously simple in structure easy to implement, and can be for the water injection vacuum pump of chlorine dioxide production.
The utility model solves the technological scheme that its technical problem adopts: the water injection vacuum pump that chlorine dioxide production is used, comprise nozzle, air chamber, secondary nozzle, diffusing tube and suction tude, described nozzle is made up of 2-5 small nozzle, all small nozzles share an intake pipe, and distribute in the form of a ring, space is left in ring central position; The angle of suction tude and gas chamber sidewall is 10～90 °, and described more to have scheme be that the vertical direction angle of described suction tude and gas chamber sidewall is 30～60 °.Suction tude extend into the central position of small nozzle formation ring-type, higher than the liquid outlet of small nozzle.
The plane that described suction tude airintake direction is just forming other any two small nozzles.
Liquid, by after intake pipe, is divided into multiply water and ejects from small nozzle, has strengthened pressure and the speed of water outlet, this can form stronger negative pressure in air chamber, allow the negative pressure in air chamber more even, suction tude tilts to install, and is conducive to the extraction of air simultaneously.
Suction tude is deep into the ring center that small nozzle forms, and allows like this suction tude more approach negative pressure center, improves pumping efficiency.Higher than the liquid outlet of small nozzle, avoid being stopped up suction tude by liquid.
The utlity model has following beneficial effect: multiple nozzles are set, allow so the interior negative pressure forming of air chamber more even, reach the effect of better bleeding.Suction tude tilts to install, and allows gas and water (flow) direction more reach unanimity, and is conducive to like this extraction of air.Suction tude is deep into the ring center position that small nozzle forms, allows like this gas more approach negative pressure center, the better effects if of bleeding like this, efficiency is higher.
