stainless steel reactor repair knowledge
1, unscrew the nut on the cover of the reaction kettle reactor material will be removed, if the reaction of flammable or toxic medium should be clean.
2, the reaction kettle cover component with a magnetic stirrer together down, wrench the magnetic stirrer disassembly.
3, the top cap sealing and cooling body and the sealing cover body is connected with the thread is dismounted, the seal cover body with internal and external magnetic steel rotor and the stirring shaft out, this body support cooling off.
4, remove and replace the graphite sleeve. In order to prevent the high temperature expansion shaft, squeeze stirring shaft, shaft sleeve should adopt the gap with graphite composite. As with a tight, assembly need grinding sleeve.
5, hand hold on the stirring shaft, the inner magnetic rotor and a top head to poke out, then remove and replace graphite sleeve.
6, note: when loading and unloading will be outside the magnet by a large magnetic force to the magnet rotor inward inhaled, don’t squeeze hands when loading and unloading.
7, the stirring shaft wear serious need to be replaced, the mating surfaces must be smooth. The new change of the manual turning sleeve should operate freely, shall not block clamping phenomenon.
9, upper and lower bearings are all re installed, should be air tightness test. Confirm that the sealing parts without leakage before put into production use.
10, if not change, should promptly contact the manufacturer, so as not to damage the reaction equipment.
micro type high pressure hydrogenation reactor, hydrogenation high pressure reactor , catalytic reactor, magnetic stirring autoclave, autoclave
hydrogenation reactor is mainly used for the hydrogenation reaction, the major difference is the reaction of hydrogen is flammable and explosive gas, to prevent the leakage of hydrogen producing reactor explosion and fire, so the electrical parts are used in hydrogenation reactor explosion, such as motor selection of explosion-proof motor, heater with explosion-proof heating, temperature sensor and pressure sensor are selected explosion proof, to prevent sparks.
hydrogenation is a chemical unit process, is an organic matter and hydrogen from the reaction process, due to the hydrogen is not active, usually must have the presence of the catalyst to react. But the reaction between inorganic and hydrogen, such as nitrogen and hydrogen to produce ammonia, carbon monoxide and hydrogen to react to produce methanol in the chemical process is not called hydrogenation, and called "synthesis"".
hydrogenation in chemical production is generally divided into two kinds:
– simply increase the number of hydrogen atoms in organic compounds, organic matter into unsaturated organic saturated, such as hydrogenation of benzene to cyclohexane used in the manufacture of nylon; fish oil hydrogenation produced oil for hardening solid and storage and transportation; manufacturing process, is also a glycerin soap a hydrogenation process.
hydrogen solution – simultaneously the organic molecule is broken and the hydrogen atom is added. If the coal or heavy oil through the hydrogen solution, into a small molecule liquid state of artificial petroleum, can be obtained by fractionation of synthetic gasoline.
four parallel reactor by 4 reactors tested at the same time, each reaction vessel equipped with a separate heating, stirring and pressure components, ensure that each reactor is independent on temperature, pressure and stirring speed of different reaction conditions, optimize, accelerate the test conditions. For the screening of chemical reaction conditions, in the shortest possible time to build the best reaction conditions, as far as possible to shorten the research and development time, to ensure that the new product has a competitive advantage and the special design of the reaction device. Reaction and volume can be freely combined, the minimum is 10ML, the maximum volume of 500ML, SLP parallel reactor, there are 2, 4, 6, 8 and other parallel reactor, according to the specific circumstances of the experiment. SLP parallel reactor to the door of the show, from the pride classic separation SLM series micro reactor and SLM reactor, the performance has micro perfect, strong performance in the market, well received by users. Patent number: ZL201120305107.9 (please look for the trademark)
four parallel reactor is widely used in a variety of catalytic reaction, high temperature and high pressure synthesis, hydrogenation, gas-liquid, liquid-liquid two-phase, exothermic reaction, composition test, stability test, corrosion resistance, fine chemicals, supercritical reaction, catalyst evaluation and development of applications, mainly in the petrochemical, chemical, pharmaceutical, metallurgy and other fields of polymer synthesis.
