Description
Technical field
This utility model relates to chemical field, particularly relates to a kind of efficiently chemical industry reaction unit.
Background technology
In the chemical process that China is traditional, still reaction device is requisite a kind of chemical industry equipment, mainly wraps
Include the reactor of enamel material and stainless steel material.When this reactor is equipped with motor, stirring paddle and some other auxiliary device
After just can complete most chemical reaction, but for some High Temperature High Pressure and need catalyst chemical reaction for, this
Still reaction device has just exposed its short slab.Because these traditional reactors can not be high temperature resistant, especially can not be high pressure resistant,
Meanwhile, under the production efficiency of this still reaction is relatively low.
Therefore, according to actual production 1, the needs of 2-this series products of methylimidazole, in the urgent need to a kind of highly efficient chemical industry
Reaction unit replaces traditional still reaction device.
Summary of the invention
The purpose of this utility model is aiming at above technical problem, it is provided that a kind of efficiently chemical industry reaction unit, substantially increases product
The response rate of product and work task efficiency.
Technical problem of the present utility model is mainly addressed by following technical proposals:
A kind of efficiently chemical industry reaction unit, including kettle, kettle cover and bottom valve, it is characterised in that: described kettle periphery is provided with heating
Tank, described heating tank top is provided with oil filler, and bottom is provided with fuel outlet, is provided with helical form electrical heating pipe ring inside described heating tank
Arranging around kettle, described bottom valve is communicated with the charging aperture of kettle, and this charging aperture connects feed pipe, and feed pipe is provided with feed pump,
Described kettle cover center is provided with discharging opening, and this discharging opening connects discharge nozzle, and discharge nozzle is provided with the cooling tube wrapping up its periphery, described
Cooling tube tail end is water inlet, and head end is outlet.
Concrete, described discharge nozzle is provided with left and right sides outlet, and side is provided with back pressure valve, and side is provided with common valve, and two
Side outlet connects same vomit pipe, and described back pressure valve side is provided with Pressure gauge.
Concrete, described kettle cover is provided with Pressure gauge, manhole.
Further, described electric heating tube base is at the fixing also external power supply of bottom valve.
Further, use conduction oil as heat transfer medium in described heating tank.
Further, the internal catalyst filling of described kettle.
Operation principle is, first by solid for kettle catalyst, this catalyst is phosphoric acid-SiO 2 catalyst, and diameter is about
The spherical shape (forming through Muffle furnace calcining) of 0.5cm.It is then turned on electric heating tube, utilizes conduction oil as heat transfer medium by anti-
Temperature in pipe should be heated to 250-300 DEG C.Utilize feed pump will be dissolved in 2-methylimidazole solution (methanol and the 2-methyl of methanol
Imidazoles be this reaction required for reactant) catalyst that slow transits through in reactor, the most just generate the product that we need
DMIZ 1,2 dimethylimidazole.The present invention is designed bottom and is fed by feed pump, and discharging is to utilize high temperature upwardly through equipped with urging in pipe
The kettle of agent is then in top discharging.Can only discharge from top discharging opening owing to feed pump exists certain air pressure, i.e. material.
So can be by 3 meters of long tube length of reaction tube of tradition once to 6 meters, the effective length of such reaction tube just expands and is twice, and is greatly improved
The yield of product.
The beneficial effects of the utility model are: utilize this tubular reactor, it is to avoid before utilize still reaction concentration step (with
Front this product needed of production is all the reactant containing moisture, and reaction is over needs dehydration to concentrate) because this concentration step needs
Consuming substantial amounts of heat energy to remove water, concentrated solution finally distills and obtains finished product, and its yield only has about 70%.And utilize this electric heating
Tubular reactor, easy and simple to handle, save the step of concentration, the yield of product has also brought up to about 90% simultaneously.
