Abstract
A jet-type inner-loop reactor comprises a first reactor, a venture tube arranged at the bottom of the first reactor, a circulating pump connected with a liquid inlet of the venture tube via a first pipeline, and a second reactor connected with the bottom of the circulating pump via a second pipeline. A reactant gas outlet on the top of the second reactor is connected with a gas inlet of the venture tube via a third pipeline. A reactant liquor inlet on the top of second reactor is connected with a reactant liquor outlet on the top of the first reactor via a fourth pipeline. A reactant gas inlet is arranged at the site of the gas inlet of the venture tube. The reactor can increase the contact time between the reactant gas and reactant liquor, and the load capacity of the reactor is increased above 70%. Additionally, although a large quantity of liquids flow inside the reactor, the heat-transfer coefficient of liquid is far larger than that of the gas such that the reaction heat is easy to eliminate. The reactor is particularly suitable for the carbonylation reaction, such as the reaction of CO with alcohols, esters, epoxy compounds, alkenes halogenated hydrocarbons.
Description
Technical field
The utility model relates to a kind of reaction unit, particularly a kind of gas-liquid two-phase reaction unit of indissoluble gases.
Background technology
The reaction of the gas-liquid two-phase of indissoluble gases, its reaction speed depends on the mass transfer velocity of gas, so reaction unit will directly determine the efficient of reacting.United States Patent (USP) (US4424375) has been introduced a kind of a kind of oxonation device that utilizes the design of Venturi tube principle.This device is got to nozzle with reactant liquor with circulating pump, sucks CO simultaneously, and CO and reactant liquor are fully mixed, and forms vaporificly, enters in the CO atmosphere of reactor, collects reaction solution in the bottom of reactor, is provided to nozzle again with circulating pump consistently then.Be not difficult out from the accompanying drawing of described patent, having only from nozzle is to have mixed with gas fully through this part reactant liquor that is reacted to reactor bottom, and from the reactor bottom to the circulating pump again this part reactant liquor to Venturi tube can not contact with gas.
In order to strengthen reaction, must possess two conditions: the 1st, add big cycle volume; The 2nd, prolong the distance of liquid through CO atmosphere.Therefore, in essence, the also inreal solution energy consumption of United States Patent (USP) is big, the shortcoming that the reactor utilization rate is low.The oxonation device of Japan scholar design (drawing collection of thesis " South China Science ﹠ Engineering University, leaf is for opening " 1994. Chengdu from the synthetic fine chemicals technical seminar of carbonyl) adopts the gas spray regime, solves the contact of gas-liquid two-phase.Basic principle is to adorn a gas jetpump that makes progress at the bottom of the tower of bubble column, input liquid when gas sprays, and very tiny bubble is scattered in the liquid of rising, thereby forms bubble column.The very high speed of gas is sprayed by nozzle, and the gas-liquid two-phase contact is good, thereby obtains very big mass transfer surface.
Above-mentioned reaction is to utilize gas as working media, and a large amount of gases at a high speed form good gas-liquid exchange by nozzle inhalant liquid body.And for oxonation, this a large amount of gas surpasses chemical consumption, must cause the reactor activity coefficient little.Simultaneously, occupied by a large amount of gas in the reactor, most of liquid is immobilising relatively (only extremely a spot of liquid is sucked by nozzle), therefore, makes the thermal efficiency lower.
Summary of the invention
The utility model technical issues that need to address are circulation oxonation devices in a kind of injecting type of design, to overcome the above-mentioned defective that prior art exists.
The technical solution of the utility model:
Circulation oxonation device in a kind of injecting type comprises:
The bottom is provided with first reactor of feed(raw material)inlet;
Be arranged on the Venturi tube of the bottom of first reactor;
The circulating pump that is connected by first pipeline with the liquid inlet of said Venturi tube;
With said circulating pump by second pipeline and its second reactor of being connected of bottom, the reaction gas outlet of second reactor head is connected with the gas access of said Venturi tube by the 3rd pipeline, and the reactant liquor inlet of second reactor head is connected with the reactant liquor outlet of first reactor head by the 4th pipeline;
Reaction gas inlet is arranged on the place, gas access of Venturi tube.
The utility model is operation like this:
The liquid inlet of Venturi tube got to reactant liquor by circulating pump from second reactor, in Venturi tube, form negative pressure, thereby make the gas access sucting reaction gas of Venturi tube, reacting gas and reactant liquor fully mix and are saturated, until first reactor is full of, and the reacting gas of excessive suction up draws along with liquid, well-mixed reactant liquor sprays into second reactor from the 4th pipeline of reactor head, reactant liquor arrives the bottom through the reacting gas atmosphere, enter first reactor by circulating pump again, the intact reacting gas of unreacted is inhaled into first reactor by the 3rd pipeline and the new reacting gas that replenishes by said Venturi tube from second reactor head;
By above-mentioned disclosed technical scheme as seen, the utility model can make increase greatly the time of contact of reacting gas and reactant liquor, and the loading of reactor can be greater than 70%.Simultaneously, a large amount of liquid is flowing, and therefore the heat transfer coefficient of liquid, is beneficial to the derivation of reaction heat much larger than gas.The utility model can be used for general gas liquid reaction, especially can be used for oxonation, as the reaction of CO and alcohols, ester class, epoxy compounds, alkene and halogenated hydrocarbons.
