Determine the chemical products such as agent, is indispensable additive in petroleum refining industry, petroleum chemical enterprise and Macromolecular materials industry.Currently, phenol
Class generally uses autoclave isobutene to liquefy with reacting for isobutene, and the gas liquid reaction under normal pressure is made to be converted to liquid liquid under high pressure
Reaction, reaction is uniform, and object, which schedules to last, to be generated, and pollution-free, isobutene does not waste, but using autoclave to equipment requirement height, and equipment is thrown
Money is big, can not reduce product cost.And general gas liquid reaction kettle device, tail gas isobutene collect or diffuse, although investment at
This is low, but gas liquid reaction is uneven, generates a large amount of isobutene tail gas, results in a large amount of wastage of material in this way, and then improve
Product cost.Therefore, it is necessary to be improved.
Invention content
The purpose of this utility model is in view of the deficiency of the prior art, to provide a kind of phenols and isobutene reaction
Device, it has the characteristics that pipeline branch is few, simple in structure, can make reaction evenly, improves production efficiency, saves raw material,
Product cost is set to be greatly reduced.
To achieve the goals above, technical solution used by the utility model is：A kind of phenols is filled with isobutene reaction
It sets, including reaction kettle, condensing unit and PLC controller, blender is provided on reaction kettle, the blender includes stirring electricity
Machine and the stirring rod being connected with stirring motor, the stirring motor are arranged in the upper end of reaction kettle, and the stirring rod is arranged anti-
It answers in kettle, which is additionally provided with gas circulating tube, and the both ends of the gas circulating tube are arranged in the upper end of reaction kettle, the gas
On body circulation pipe by air current flow direction be disposed with pressure sensor, condensing unit, cycle air pump, electromagnetic valve A and into
Tracheae is provided with electromagnetic valve B in the air inlet pipe, the outlet side of several and gas circulating tube is provided in the reaction kettle
The micro porous aeration head of connection；Pressure sensor, cycle air pump, electromagnetic valve A, electromagnetic valve B and the stirring motor difference
It is electrically connected with PLC controller.
The stirring rod is U-shaped.
With the above structure, the utility model is compared to the prior art advantageously：The utility model uses
Single gas circulating tube, setting cycle air pump and micro porous aeration head, have pipeline branch on the circuit that gas circulating tube is formed
Road is few, simple in structure, and the low feature of equipment cost keeps gas liquid reaction evenly abundant, tail gas is not generated in reaction process, improves
The utilization rate of raw material, reduces product cost, and reaction process is pollution-free.
