Description
Technical field
The invention belongs to the extraction equipment field, be specifically related to the pulsed extraction tower and the method thereof of diaphragm metering pump as the mechanical pulsing generator.
Background technology
The pulse perforated-plate extraction tower (Wang Jiading, Chen Jiayong. the solvent extraction handbook. Chemical Industry Press, 2001; 237 pages), pulsed packed tower (Wang Jiading; Chen Jiayong. solvent extraction handbook, Chemical Industry Press, 2001; 257 pages) and the pulse baffle extraction tower be three kinds of common pulsed extraction towers, the input of its power is all accomplished by impulse generator.The classification of impulse generator can be distinguished by the power transmission medium, can distinguish by gas pulses or mechanical pulsing again.Mechanical pulsing generator in the past generally uses the piston type impulse generator; Because this kind working method piston directly contacts with the extraction tower working media; So just have two serious problems, the 1. corrosion-resistant problem of piston system is 2. because the fricative leakage problem of mechanical movement.
Summary of the invention
To the problems referred to above, the invention provides a kind ofly with the pulsed extraction tower and the method thereof of diaphragm metering pump as the mechanical pulsing generator, the present invention makes the mechanical pulsing generator work operation of pulsed extraction tower more stable, and corrosion resistance is stronger, applicable system is wider.The present invention uses diaphragm metering pump as impulse generator, and the extraction tower working media can only contact barrier film, does not therefore also just have corrosion and the leakage problem as the piston pulse generator, as long as the periodic replacement barrier film is just passable.
With the pulsed extraction tower of diaphragm metering pump as the mechanical pulsing generator, the unidirectional valve ball of the import of said diaphragm metering pump is removed, and the import of diaphragm metering pump links to each other with the following settling section of pulsed extraction tower, and the metering diaphragm delivery side of pump links to each other with blast pipe through valve.
The setting height(from bottom) of said diaphragm metering pump generally will be in the middle and lower part of last settling section, and the position should not be low excessively.
With the method for diaphragm metering pump as pulsed extraction tower mechanical pulsing generator, this method comprises the steps:
1) metering diaphragm pump inlet check valve ball is taken out (make check valve ineffective);
2) valve is installed in adjacent diaphragm metering pump exit, the valve top connects a blast pipe;
3) height of measuring pump installation is in last settling section middle and lower part;
4) the metering diaphragm pump inlet is connected with following settling section;
5) discharge whole air in the diaphragm metering pump cavity before the operation.
Diaphragm metering pump itself is with pulse mode work, with diaphragm metering pump as pulse-column mechanical pulsing generator with compare with reciprocating machine impulse generator mode, have following beneficial effect: 1. make the reliability of system increase stable equipment operation; 2. system's corrosion resistance is strong; 3. it is wide to be suitable for extraction system; 4. be not easy to leak.
Description of drawings
Fig. 1 is a system of the present invention connection layout
Label among the figure: the 1. diaphragm metering pump pump housing; 2. measuring pump barrier film; 3. measuring pump cavity; 4. valve (being air bleeding valve); 5. pump material inlet; 6. burst transmissions pipe; 7. pulse tube tower entrance; 8. light phase materials tower entrance; 9. the heavy phase material goes out Ta Kou; 10. descend settling section; 11. extraction tower column plate or filler; 12. extraction tower tower body; 13. heavy phase material tower entrance; 14. last settling section; 15. light phase materials outlet.
The specific embodiment
The present invention will be described below in conjunction with embodiment:
Embodiment 1: system is as shown in Figure 1; Pulsed extraction tower comprises tower body 12 and is arranged at the last settling section 14 and following settling section 10 of tower body upper and lower end respectively; Extraction tower column plate or filler 11 are equipped with in tower body 12 inside; Following settling section 10 is provided with pulse tube tower entrance 7, light phase materials tower entrance 8 and heavy phase material and goes out tower mouth 9, and last settling section 14 is provided with heavy phase material tower entrance 13 and light phase materials outlet 15.
Diaphragm metering pump mainly is made up of the pump head and the diaphragm metering pump pump housing 1; The unidirectional valve ball of the import of said diaphragm metering pump is removed; The pump material inlet 5 of diaphragm metering pump links to each other with the pulse tube tower entrance 7 of the following settling section 10 of pulsed extraction tower through burst transmissions pipe 6, and the metering diaphragm delivery side of pump links to each other with blast pipe through valve (being air bleeding valve) 4.
The said diaphragm metering pump pump housing 1 comprises motor and mechanical driving part and piston etc.The metering diaphragm pump housing 3 that is positioned at pump head is a flat arc-shaped cavity, and measuring pump barrier film 2 is positioned in the middle of two and half arcs, and measuring pump barrier film 2 connects with piston, and the reciprocating motion of piston has driven the reciprocating motion of barrier film 2, thereby has driven the reciprocating motion of liquid in the tower.
The setting height(from bottom) of said diaphragm metering pump is in the middle and lower part of last settling section 14, and making can be a little more than air bleeding valve 4 from the liquid level of burst transmissions pipe.Setting height(from bottom) is in the reason of the middle and lower part of last settling section 14: the too high words in measuring pump installation site can cause from the liquid level of burst transmissions pipe low excessively, thereby can't discharge the gas in the metering diaphragm pump housing 3 fully; The measuring pump installation site is low excessively, and it is excessive to make measuring pump barrier film 2 bear pressure, influences service life.
