Description

A kind of high performance membrane reaction unit

Technical field

The utility model belongs to the chemical production equipment technical field, especially relates to a kind of high performance membrane reaction unit of accelerated reaction speed.

Background technology

At present in chemical industry, liquid-the liquid or the gas-liquid reactions that often have different qualities are produced, especially in esterification reaction, be the aqueous favoring material with hydrophobic mutually material react, esterification between them is very slow, main cause be between the molecule between the two-phase fully time of contact and area is too little, too short, make esterification very slow, production efficiency is very low; Particularly energy shortage at present, biodiesel becomes a kind of effective way that substitutes conventional diesel, biodiesel claims Fatty acid methyl ester (second fat) again, be by animal and plant fat (its main component is the glyceryl ester of higher fatty acids) is carried out the fatty acid methyl ester (second fat) that alcoholysis makes with methyl alcohol (ethanol), has recyclability, high biodegradation, nontoxic, advantages such as noxious emission is few in the low and waste gas of sulfur content, character is similar to ordinary diesel oil, need not simultaneously existing diesel is changed, facility compatibility to oil transportation distribution is good, so market is easier to accept, its production technology is a kind of esterification and ester exchange process in essence, it is the green energy resource technology that grows up at the specific (special) requirements of biodiesel on the basis of oil chemistry and oil and fat chemical, and formed different technical systems, as chemical catalysis, catalyzed by biological enzyme, HTHP (catalyst-free) alcoholysis method or the like, the wherein esterification of the biodiesel of chemical catalysis, the transesterification reaction temperature height, speed is slow, time is long, the energy consumption height, per unit area yield is low, the reaction finish for up to 8 hours, even reach more than 10 hours, sometimes reached molecular balance, reaction time is oversize, causes the quality decline of product and can't reach qualified result.

Summary of the invention

The purpose of this utility model be to improve the deficiency of prior art and provide strengthen the reactive material contact area, extend contact time, effectively improve reaction speed, reduce its reaction temperature, power consumption reduces, improve output, high performance membrane reaction unit that product quality is high.

The purpose of this utility model is achieved in that a kind of high performance membrane reaction unit, is made up of reactor, agitating device, pipeline, pump machine and switch board, is characterized in being provided with on the pipeline between pump machine and the reactor the mixed high performance membrane reaction tower of material.

In order further to realize the purpose of this utility model, can be that the mixed high performance membrane reaction tower of described material is to be provided with vertical placed metal tunica fibrosa in the tower body, tower body top is charging aperture, the bottom is a discharging opening.

The utility model is compared in prior art has following distinguishing feature and good effect: the utility model adopts and be provided with the mixed high performance membrane reaction tower of material on the pipeline between pump machine and the reactor, the mixed tower of material is to be provided with vertical placed metal tunica fibrosa in the tower body, tower body top is charging aperture, the bottom is a discharging opening, material enters from import like this, flow from top to bottom, during the metallic fiber film of two-phase material flow in the mixed high performance membrane reaction tower of material, effective must the increase between the not miscible liquid-liquid phase, carry out the mass transfer chemical reaction between the solution-air phase, make two-phase medium contact area when contact improve more than 100 times, prolonged time of contact, effectively improve its reaction speed, reduce its reaction temperature; Apply to the production of biodiesel, improved reaction speed greatly, reduced reaction temperature, power consumption reduces greatly in the production, and energy consumption reduces more than 30%, and its output improves more than the twice; The utility model has the field of using widely at biodiesel, petrochemical industry, chemical industry, organic synthesis, medicine, bioengineering etc.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a kind of structural representation of the present utility model.

The specific embodiment

Embodiment, a kind of high performance membrane reaction unit, with reference to Fig. 1, be in reactor 1, to be provided with agitating device 2, on the pipeline 3 between pump machine 4 and the reactor 1, be provided with the mixed high performance membrane reaction tower 5 of material, the mixed high performance membrane reaction tower 5 of material is to be provided with vertical placed metal tunica fibrosa 7 in the tower body, tower body top is charging aperture, the bottom is a discharging opening, switch board 6 control pump machines 4, reactor 1, material mixes high performance membrane reaction tower 5, agitating device 2 work, the major function of switch board 6 is flow velocitys of control material, flow, the opening of mechanical stirring device, stop, rotating speed, the frequency of motor, the advancing of material, output, the chemical parameters characteristic of detection material, divide manual and automatic function, have remote transmission and control function, this constitutes a kind of structure of the present utility model.

When using the utility model, feed product is added in the reactor 1, material begins mixed reaction, opens the valve of reactor 1 bottom, and pump machine 4 will 3 pump into the charging aperture that material mixes high performance membrane reaction tower 5 by the road from the material that reactor 1 flows out, the material metallic fiber film 7 of flowing through from top to bottom, 3 flow back to reactor 1 by the road from the discharging opening outflow, so circulation, reaction is finished, close pump machine 4, from reactor 1, emit material and get final product.
