Abstract
A distributor of a trickle bed reactor comprises a flowmeter 1, an overflow distributor 2, a reaction tube 3, an air inlet tube 6, a thermostatic bath 7 and other components, wherein an air compressor 4 is arranged at the top of the overflow distributor 2, the air inlet tube 6 is arranged in the overflow distributor 2, the reaction tube 3 is arranged at the upper part of the air inlet tube 6, the thermostatic bath 7 is arranged in the reaction tube 3, and a gas flowmeter 5 is arranged at the bottom of the reaction tube 3, so that the requirements of stable fluid feeding at low liquid velocity, uniform distribution along different axial sections of the reaction tube and normal distribution can be met, the reaction process requirements of synthesizing methyl isobutyl ketone by a composite acetone one-step method are completely met, the conditions of the low liquid velocity of 0.01-0.15 m/min and the gas velocity of 0-14.7 m/min are met, and the flow is not limited by the number of tubes.
Description
Relate to the field
The utility model relates to the gas-liquid-solid phase reaction device, promptly a kind of trickle bed reactor distributor that is applicable to the low liquid speed situation and is not subjected to how many restrictions of reactor tube number.
Background technology
Trickle bed reactor is the gas-liquid-solid phase reaction device, be generally adiabatic reactor, in the liquid-phase hydrogenatin reaction, use more, for the shell and tube trickle bed reactor, because the structure more complicated, use less, so rarely have the research report, particularly study for low liquid speed shell and tube trickle bed reactor, do not appear in the newspapers as yet, the shell and tube trickle bed reactor is applicable to the course of reaction that range of temperature is narrow, require the reactor good effect of heat exchange, individual reaction tube inner fluid flow is consistent and along the axial different cross section even fluid distribution of reaction tube.EP1032117 has invented a kind of gas-liquid mixed distributor, is used for the shell and tube trickle bed reactor, and this distributor is suitable for high liquid speed situation, and during low liquid speed, gas flow variable effect liquid distributes in the equivalent of individual tubulation; CN2430213 has invented a kind of liquid distribution trough, is used for shell and tube reactor, but the managed number restriction of this distributor is not suitable for the more situation of pipe number.
Technology contents
The purpose of this utility model is to provide a kind of trickle bed reactor distributor that satisfies the low liquid speed situation and be not subjected to how many restrictions of reactor tube number.
The utility model is achieved in that
The utility model also adopts following technical scheme:
Air inlet pipe 6 has overfall.
Thermostat 7 is the narrow slot structure.
Funnel type fan mouth is arranged respectively on reaction tube 3, the gas flowmeter 5.
Advantage of the present utility model is: it is stable and be evenly distributed along the axial different cross section of reaction tube to satisfy under the low liquid speed fluid feed, keep normal distribution, compound acetone one-step method synthesize methyl-isobutyl reactive ketone technological requirement, be adapted to flow rate of liquid fully at 0.01～0.15m/min, gas flow rate is in the low liquid speed situation of 0～14.7m/min, and what the restriction of not managed number.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a fluid distribution experiment flow schematic diagram of the present utility model.
Concrete enforcement
As shown in Figure 1 and Figure 2, liquid (being water in the experiment) is through flowmeter 1, overflow distributor 2, enter reaction tube 3, the gas (being air in the experiment) that is come out by air compressor 4 enters reaction tube 3 through gas flowmeter 5, air inlet pipe 6, the following L=300 of reaction bed, 1100 and the cross section of 1800mm on, respectively at implanting 3 thermocouple T1 (left wall), T2 (center), T3 (right wall), T4 (left wall), T5 (center), T6 (right wall) and T7 (left wall), T8 (center), T9 (right wall) that diameter is 0.6mm on the center in each cross section and the symmetrical wall.When carrying out pulse test, enter tube sheet liquid weir notch with hot water through flowmeter from the spike of thermostat 7, enter reaction tube 3 by distributor.
Claims (4)
