Description
Technical field
The present invention relates to chemical field more particularly to a kind of energy-saving efficient tubular reactors.
Background technique
In the traditional chemical production process in China, kettle reactor is a kind of essential chemical industry equipment, wherein
Main includes the reaction kettle of enamel material and stainless steel material.When the reaction kettle is equipped with motor, agitating paddle and some other
It just can complete mostly to chemically react after auxiliary device, but for some high temperature and pressure and the chemical reaction for needing catalyst
For, this kettle reactor has just exposed its short slab.Because these traditional reaction kettles are unable to high temperature resistant, especially
Cannot be high pressure resistant, meanwhile, under the production efficiency of the still reaction is relatively low.
Therefore, according to actual production 1, the needs of 2- methylimidazole this kind of product, there is an urgent need to a kind of more energy saving high
Acting type tubular reactor replaces traditional kettle reactor.
Summary of the invention
The purpose of the present invention is to the above technical problems, provide a kind of energy-saving efficient tubular reactor, mention significantly
The high reactivity and work task efficiency of product.
Technical problem of the invention is mainly addressed by following technical proposals:
Energy-saving efficient tubular reactor, including autoclave body, kettle cover and bottom valve, it is characterised in that: the autoclave body periphery is equipped with
Heating tank, the heating tank are equipped with electric heating tube, are equipped with inner tube, said inner tube bottom opening, said inner tube inside the autoclave body
It is top closed and be fixed on autoclave body and kettle cover junction center, it is equipped at the top of the inner tube outside discharge port connection autoclave body, it is described
Discharge port connects discharge nozzle, and discharge nozzle is equipped with the cooling tube for wrapping up its periphery.
Specifically, the electric heating tube is symmetrically distributed in heating tank two sides, every upper lateral part is divided into the electric heating being obliquely installed
Pipe, lower part is divided into vertically set electric heating tube.Described electric heating tube or so is respectively set three.
Specifically, the kettle cover is equipped with feed inlet, pressure gauge, which connects feed pipe, and feed pipe is equipped with feed pump.
Specifically, the cooling bottom of the tube is water inlet, top is water outlet.
Specifically, the discharge nozzle is exported equipped with the left and right sides, side is equipped with back pressure valve, and side is equipped with common valve,
And two side outlet connect jointly bottom valve lower end setting vomit pipe.The back pressure valve side is equipped with pressure gauge.
Specifically, the heating upper end is equipped with oil filler, bottom end is equipped with fuel outlet.
Working principle is, first by the solid catalyst of autoclave body, which is phosphoric acid-SiO 2 catalyst, diameter
The about spherical shape of 0.5cm (being calcined by Muffle furnace).It is then turned on electric heating tube, as a heat transfer medium using conduction oil
Temperature in reaction tube is heated to 250-300 DEG C.2-methylimidazole solution (methanol and the 2- of methanol will be dissolved in using feed pump
Methylimidazole is reactant required for the reaction) catalyst in reactor is slow transitted through, our needs are just generated at this time
Product DMIZ 1,2 dimethylimidazole.The raw footage of the reaction tube is 3 meters, but it is exactly to allow script future that the present invention, which devises inner tube,
And reaction 2-methylimidazole and methanol discharge hole for discharge not from below but continued upward through in pipe using waste heat
Then tubule equipped with catalyst discharges above.Since there are certain air pressures for feed pump, i.e. material can only be from intermediate inner tube
Discharge.So can be by 3 meters of long tube length of reaction tube of script once to 6 meters, the effective length of such reaction tube, which just expands, to be twice, simultaneously
The reactant reacted not in time only needs to absorb a small amount of heat and just can react, and the yield of product is just substantially increased with this.
The beneficial effects of the present invention are: avoiding the concentration step for utilizing still reaction in the past using the tubular reactor
(produced product needs in the past is the reactant containing moisture, and reaction, which is over, to be needed to be dehydrated concentration), because the concentration walks
Suddenly it needs to consume a large amount of thermal energy to make a return journey water removal, concentrate, which finally distills, obtains finished product, and yield only has 70% or so.And it utilizes
The electric heating pipe type reactor, easy to operate, the step of saving concentration, while the yield of product has also been increased to 90% or so.
