Abstract
The utility model discloses a mixing and stirring device for polyoxyethylene ether non-ionic surfactants and solves the technical problem that a large amount of energy is wasted and a lot of man power is needed for installation for the usage of stirrers, gas bubbles are inconvenient to be used for stirring for demand limits of gas sources and materials. The technical scheme includes that the mixing and stirring device comprises a reaction kettle and is characterized in that a tank bottom of the reaction kettle is in an inversed cone shape, a distributor is vertically mounted in a conical body of the tank bottom, and at least one flute-shaped nozzle is vertically fixed on the lower portion of the distributor; and a feed port is opened at a conical top of the tank bottom, a discharge port is opened on the lateral wall of a tank, a circulation line is paved between the feed port and the discharge port, a tee is arranged on the circulation line, and each port of the tee is provided with a valve. The mixing and stirring device for polyoxyethylene ether non-ionic surfactants has the advantages that cases that nitrogen is wasted and other units are affected and uneven stirring caused by dead angles due to insufficient nitrogen pressure cannot exist, the structure is simple, and the operation is convenient and simple.
Description
Technical field
The utility model relates to a kind of chemical industry agitation mixer, provides specifically a kind of Polyoxyethylene Ether Nonionic Surfactant mixed stirring device.
Background technology
Composite fluid product mixed method commonly used is to stir with agitator or with gas sparging.If container is larger, the use agitator can cause the waste of mass energy and need a large amount of manpowers to install, and uses gas sparging to stir because the requirement of source of the gas and material limits sometimes also inconvenient.Particularly when producing Polyoxyethylene Ether Nonionic Surfactant, to use nitrogen to stir, not only waste a large amount of nitrogen, sometimes also can affect other unit productions and the situation that the dead angle makes the stirring inequality occur because nitrogen pressure is not enough.
Surfactant monomer is synthetic to be to adopt the outer circulation polymerization technique, and a certain amount of phenol is added in the pre-treatment still, and vacuum sucks material total amount 0.2% catalyst potassium hydroxide, afterwards this material is squeezed in the reactor, behind the nitrogen replacement, heats up and starts circulating pump.When temperature in the kettle reaches 120～140 ℃, add oxirane, control reaction temperature at 150～170 ℃, reaction pressure 0.3～0.4Mpa.Behind the oxirane that adds ormal weight, aging 30～50 minutes, when no longer descending to pressure, add again expoxy propane, control reaction temperature at 150～170 ℃, reaction pressure 0.3～0.4Mpa.Behind the expoxy propane that adds ormal weight, aging 30～50 minutes, when no longer descending to pressure, react complete, material is squeezed in the post processing still cooling, neutralization.Afterwards the qualified product is squeezed in the finished pot, discharging namely gets surfactant monomer.
Summary of the invention
The purpose of this utility model provides a kind of mixed stirring device that uses when producing Polyoxyethylene Ether Nonionic Surfactant.
The purpose of this utility model is achieved in that it comprises reactor, is characterized in that: the tank base of reactor is back taper, and distributor vertically is installed in the tank base cone, fixes at least one flute shape nozzle in the distributor lower vertical; Have charging aperture at the tank base vertex of a cone, have discharging opening at tank wall, lay cycle pipeline between charging aperture and the discharging opening is installed a threeway at pipeloop, lays feeding line at the branch road of threeway, the equal mounted valve of each port of threeway.Between charging aperture and threeway, feed pump is installed.
In order to make stirring more even, distributor is tubular, the uniform discharge opening of helical form on barrel.Flute shape nozzle mouth mouth up.
Open the feed pump valve when carrying out the production charging, close circulating valve, this moment, material entered in the tank body by nozzle and distributor, and material forms eddy current and will be rolled into by the material that distributor flows out to reach in the whirlpool and makes the uniform effect of mixing of materials in tank under nozzle act.After charging is complete inlet valve cuts out, pressure opening circulating valve carries out circulation stirring.
The utlity model has following advantage: can not waste nitrogen and affect other unit productions and the dead angle occurs because nitrogen pressure is not enough and make the situation that stirs inequality, the characteristics such as the utility model also has simple in structure, and is easy and simple to handle.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is structural representation sketch of the present utility model;
Utility model is described in further detail by example below in conjunction with accompanying drawing; but following example only is the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claim.
The specific embodiment
Referring to Fig. 1, the tank base of reactor is back taper, and distributor 2 vertically is installed in tank body 1 bottom cone, fixes two each and every one flute shape nozzles 3 in the distributor lower vertical; Have charging aperture at the tank base vertex of a cone, have discharging opening at tank wall, lay cycle pipeline between charging aperture and the discharging opening, at pipeloop a threeway is installed, branch road in threeway is laid feeding line, and each port of threeway is installed respectively charging pump valve 6, circulating valve 4, master control valve 7.Feed pump 5 is installed between charging aperture and threeway.
In order to make stirring more even, distributor is tubular, the uniform discharge opening of helical form on barrel.Flute shape nozzle mouth mouth up.
Open charging pump valve and master control valve when carrying out the production charging, close circulating valve, this moment, material entered in the tank body by nozzle and distributor, and material forms eddy current and will be rolled into by the material that distributor flows out to reach in the whirlpool and makes the uniform effect of mixing of materials in tank under nozzle act.After charging is complete inlet valve cuts out, pressure opening circulating valve carries out circulation stirring.
