Description

A kind of gas-liquid exchanger structure and the gas-liquid switch type gas compressor with the mechanism

Technical field

The present invention relates to machinery fields, specifically, being related to a kind of gas-liquid exchanger structure and the gas-liquid friendship with the mechanism Change formula gas compressor.

Background technology

Gas compressor is a kind of universal machine that purposes is very extensive, in compressed air, natural gas compressing and transport, is changed It is essential production equipment in the fields such as work, refrigeration, it may be said that be related to compressed gas all and pass through compressed gas Body all be unable to do without gas compressor in the field that produces and run.Currently, being widely used in the gas pressure in each gas field Contracting owner will have reciprocating compressor and rotary compressor two major classes, wherein reciprocating compressor includes various piston type pressures Contracting machine and reciprocating hydraulic formula compressor etc., rotary compressor include various screw compressors, centrifugal compressor, axial-flow type Compressor, liquid-piston compressor, sliding-vane compressor, scroll compressor etc..

When above-mentioned gas compressor normal operation, there is a common technological deficiencies always --- and above-mentioned gas compresses Machine always has quite a few gas to need repeated compression that could finally be pressed into high-pressure area in compressed gas.Such as reciprocal In formula compressor, reciprocating member (piston) between cylinder head must there are certain gaps, just can guarantee reciprocating member just in this way Often operation and normal compressed gas will lead to reciprocating member and cylinder top if very close to each other between reciprocating member and cylinder head The generation of phenomena such as portion's collision or liquid hammer, and then reciprocating compressor is damaged, therefore in reciprocating compressor, reciprocating member and gas Between at the top of cylinder must there are certain gaps, however, between reciprocating member and cylinder head must there are gap result in again Some total gas is detained in this gap and cannot disposably be pressed into high-pressure area, and which results in reciprocating pressures Contracting machine some total gas during compressed gas needs repeated compression that can finally be pressed into high-pressure area；In another example It is necessary between revolving part (screw rod, blade, slide plate, rotor, scroll etc.) and fixed cylinder block in various rotary compressors There are certain gaps, just can guarantee revolving part normal operation and normal compressed gas in this way, if revolving part and fixed gas It is very close to each other between cylinder body, phase mutual friction between revolving part and fixed cylinder block or generation phenomena such as mutually shock will be caused, And then rotary compressor is damaged, it must there are certain therefore in rotary compressor, between revolving part and fixed cylinder block Gap, however, between revolving part and fixed cylinder block must there are gap result in again always some compressed High pressure gas leaks into area of low pressure by these gaps from high-pressure area, then repeats indentation higher-pressure region further through revolving part Domain, which results in rotary compressors during compressed gas, and some total gas needs repeated compression can Final indentation high-pressure area.In conclusion existing various common gas compressors are in compressed gas, gas is repeated pressure Contracting is the shared technological deficiency present in them, and this technological deficiency results in existing various common gas compressor fortune It needs to consume and waste a large amount of energy when row that compressed gas could be produced.

Another common technological deficiency is existing for above-mentioned gas compressor：By low-pressure gas be compressed into high pressure and When extra-high, it is necessary to can be only achieved purpose using the mode of multi-stage compression.Such as in various reciprocating compressors, back and forth Maximum distance of the reciprocating member (piston) between cylinder head determines the reciprocating compression when part (piston) compression travel starts The highest compression ratio of machine, the compression ratio to improve reciprocating compressor must must just increase reciprocating member (piston) compression travel and open Maximum distance of the reciprocating member (piston) between cylinder head when the beginning, it is clear that in reciprocating compressor, reciprocating member (piston) pressure The elongation that maximum distance of the reciprocating member (piston) between cylinder head can not possibly be unlimited when indention journey starts, it is so, past Twin compressor will become very huge, while be limited by factors such as mechanical strength, stability, lubrication, coolings, reciprocating The single stage compress of compressor is limited than always, and therefore, low-pressure gas is being compressed into high pressure and surpassed by reciprocating compressor When high pressure gas, it is necessary to can be only achieved purpose using the mode of multi-stage compression.In another example in various rotary compressors, rotation Between part (screw rod, blade, slide plate, rotor, scroll etc.) and fixed cylinder block must there are certain gaps, could protect in this way Demonstrate,prove revolving part normal operation and normal compressed gas, and between revolving part and fixed cylinder block must there are gap cause Some total high pressure gas compressed leaks into area of low pressure by these gaps from high-pressure area, and rotary Number of compression stages in compressor is fewer, and high pressure gas leaks into the resistance of area of low pressure with regard to smaller from high-pressure area, high pressure gas Also easier to leak into area of low pressure from high-pressure area, therefore, in actual production, rotary compressor always needs multistage Low-pressure gas could be compressed into high pressure or extra-high by compression, even in many rotary compressors (such as screw Compressor, sliding-vane compressor, scroll compressor etc.) in, between revolving part and fixed cylinder block must there are gap, make Low-pressure gas can not be compressed into increasing number of compression stages high pressure or extra-high by obtaining them.

The working mechanism of gas-liquid switch type gas compressor：

Referring to Figure 11 and Figure 12, the process of gas-liquid switch type gas compressor normal operation, actually sealing, gas-liquid The process of exchange, gas compression and Liquid level mutual cooperation operation.So as to produce compressed gas.

Sealing --- in gas-liquid switch type gas compressor, the collective effect of each parts makes in gas-liquid exchanger structure Obtaining gas-liquid exchange mechanism has good sealing function, can be spaced from each other high-pressure bottle and low pressure vessel；Gas-liquid exchanger Sealing element between structure and high pressure vessel can will be spaced from each other between inside the high-pressure bottle and external world；Gas-liquid exchanger structure Sealing element between low pressure vessel shell can will be spaced from each other between inside the low pressure vessel and external world.

Gas-liquid exchanges --- when gas-liquid switch type gas compressor is run, under the drive of external force, and gas-liquid exchanger structure In gas-liquid exchange part and end seals assembly and will rotate, now exchanging the first groove of groove with one of gas-liquid is Example, makes an explanation to the operation principle of gas-liquid exchanger structure：If gas-liquid exchanges part and rotates clockwise, the first groove also revolves clockwise Turn, during the first groove rotates to B points by A points, the first groove gradually with the low-pressure gas chamber inside low pressure vessel 63 are connected and are finally connected completely with low-pressure gas chamber 63, under liquid dead weight and the double action of centrifugal force, originally Liquid in the first inside grooves is thrown out of the first groove and finally flows into the low pressure liquid chamber 62 inside low pressure vessel, together When low-pressure gas the first inside grooves are charged under the action of negative pressure, to realize liquids and gases inside low pressure vessel Exchange；During the first groove rotates to C points by B points, the first groove is gradually covered and final by side seal 21 It is completely covered by side seal 21, when the first groove is completely covered by side seal 21, in the first inside grooves Gas is in sealing state, can neither be connected with the low-pressure gas chamber 63 inside low pressure vessel, can not be with high pressure-volume Highly pressurised liquid chamber 72 inside device is connected, and can not be connected with external environment, ensures that in this way in the first groove The gas in portion can be transported to by the first groove inside high-pressure bottle；During the first groove rotates to D points by C points, First groove be gradually connected with the highly pressurised liquid chamber 72 inside high-pressure bottle and it is final completely with 72 phase of highly pressurised liquid chamber Connection, low-pressure gas of the first inside grooves is totally submerged inside in highly pressurised liquid chamber 72 during this, due to gas Density is small more than the density of liquid, thus the gas of the first inside grooves the first groove can be progressively disengaged under the action of buoyancy and It floats in the high pressure gas chamber 73 inside high-pressure bottle, and the space of the first inside grooves is then filled by liquid, from And realize exchange of the liquids and gases inside high-pressure bottle；During the first groove rotates to A points by D points, first Groove is gradually covered by side seal 21 and is finally completely covered by side seal 21, when the first groove is by side seal 21 it is completely covered when, be in sealing state in the liquid of the first inside grooves, can neither be with the height inside high-pressure bottle Hydraulic fluid fluid chamber 72 is connected, and can not be connected with the low-pressure gas chamber 63 inside low pressure vessel, can not be with the external world Environment is connected, and ensures that the liquid of the first inside grooves can be transported to by the first groove inside low pressure vessel in this way. It will be evident that when the first groove re-rotates to A points by A points, a working cycle process is completed, when gas-liquid exchanges part not When rotating disconnectedly, gas continuously will flow into the low-pressure gas chamber 63 inside low pressure vessel by low-pressure gas source, then pass through Each groove that gas-liquid exchanges in part is transported to inside high-pressure bottle, while the liquid inside high-pressure bottle is exchanged also by gas-liquid Each groove in part is transported to inside low pressure vessel, so that the gas inside the liquid and low pressure vessel inside high-pressure bottle Body can be swapped constantly.

Gas compression --- when gas-liquid switch type gas compressor is run, under the drive of external force, in hydraulic system Constantly by inside the liquid indentation high-pressure bottle in low pressure vessel, the liquid being pressed into inside high-pressure bottle acts on hydraulic pump There are two main：When the liquid that supplement gas-liquid exchanger structure is taken away inside high-pressure bottle, in gas-liquid switch type gas compression In machine, inside high-pressure bottle cannot not no liquid, if liquid not enough inside high-pressure bottle, then, by low pressure Gas inside container delivered inside to high-pressure bottle will be by each trough return current to low pressure vessel inside, it is so low Gas inside pressure vessel can be not transported to inside high-pressure bottle, needless to say be had compressed；Second is that compressed gas, In gas-liquid switch type gas compressor, since the volume inside high-pressure bottle is fixed and limited, liquid is in high-pressure bottle The volume in portion is also dynamic stability, in this case, when compressible gas and incompressible liquid are all constantly defeated When being sent to inside the high-pressure bottle of finite volume, compressible gas will necessarily be compressed by incompressible liquid, to produce Raw compressed gas.

Liquid level --- when gas-liquid switch type gas compressor is run, due to the influence of various factors, hydraulic pressure pump pressure Gas-liquid exchanger structure liquid of discharge inside high-pressure bottle can not be consistently equal to by entering the flow of the liquid inside high-pressure bottle Flow.If the flow that hydraulic pressure is pumped into the liquid inside high-pressure bottle is frequently larger than gas-liquid exchanger structure inside high-pressure bottle The flow of the liquid of discharge, then the liquid level inside high-pressure bottle will constantly rise, is finally led without being controlled Liquid is caused to be discharged into gas equipment by the high pressure gas outlet being equipped in high pressure gas chamber, due to gas-liquid switch type gas pressure Liquid in contracting machine is limited, will result in that liquid stock inside low pressure vessel is reduced in the course of time and cannot recycle makes With in turn resulting in entire gas-liquid switch type gas compressor and be unable to operate normally；If hydraulic pressure is pumped into inside high-pressure bottle The flow of liquid is frequently less than the flow for the liquid that gas-liquid exchanger structure is discharged inside high-pressure bottle without being controlled, then Liquid level inside high-pressure bottle will constantly decline, and eventually lead to the high pressure gas inside high-pressure bottle and handed over each gas-liquid It changes groove to be in direct contact, then high pressure gas will exchange groove by each gas-liquid and leak into low pressure vessel, in turn result in entire Gas-liquid switch type gas compressor is unable to operate normally.Therefore in order to ensure that gas-liquid switch type gas compressor can be transported normally Row, must be configured with tank level control system in gas-liquid switch type gas compressor.Tank level control system is the prior art in gas Application in liquid switch type gas compressor, effect be control high-pressure bottle inside liquid level, be allowed to always be in set In fixed effective range, and then ensure the normal operation of gas-liquid switch type gas compressor, tank level control system is to pass through adjusting Hydraulic pressure is pumped into the stream of the flow and gas-liquid exchanger structure liquid of discharge inside high-pressure bottle of the liquid inside high-pressure bottle Difference between amount controls the liquid level inside high-pressure bottle.

When gas-liquid exchanger structure is run, the low-pressure gas inside low pressure vessel is constantly transported in high-pressure bottle Portion then will appear negative pressure inside low pressure vessel, and under the action of negative pressure, the gas of extraneous low-pressure gas source can be pressed into low automatically Inside pressure vessel, to constantly provide low-pressure gas for low pressure vessel.

The beneficial effects of the present invention are：First, gas-liquid switch type gas compressor of the invention has good sealing Property.Without mechanical clearance in gas-liquid switch type gas compressor, across thickness thickness between high pressure gas and low-pressure gas Liquid, therefore area of low pressure, and gas-liquid switch type gas compressor can be leaked into from high-pressure area almost without gas Low-pressure gas can be disposably transported to high-pressure area, the degree of gas repeated compression can be preferably minimized, Jin Erda Energy-efficient effect is arrived.Secondly, gas-liquid switch type gas compressor of the invention has good cooling effect, in gas-liquid In switch type gas compressor, compressed gas needs just be transported in high-pressure area across one layer of liquid, compressed gas Good cooling is obtained during across liquid level, therefore closer when gas-liquid switch type gas compressor compressed gas In isotherm compression, and then achieve the effect that energy-efficient.Again, gas-liquid switch type gas compressor of the invention has high Single stage compress ratio, in gas-liquid switch type gas compressor, the output pressure of compressed gas is not limited by mechanical dimension. Theoretically, the output pressure of compressed gas is the not no upper limit in gas-liquid switch type gas compressor, as long as gas-liquid switch type gas The mechanical strength of gas compressor is sufficiently strong, then it only needs one stage of compression that can export the gas of enough pressure, rather than Existing various gas compressors need multi-stage compression that could export the gas of enough pressure like that, this technical characteristic is existing Any type gas compressor not available for, this feature can make gas-liquid switch type gas compressor structure simpler List, cost is less expensive, manufacture is more convenient, repair is easier.
