Description
Technical field
A kind of method that the present invention relates to gas-liquid exchange device and adopt this device to carry out gas-liquid exchange, belongs to gas-liquid switching technology field.
Background technology
Gas-liquid exchange is an industrial common technology, and the adequacy of gas-liquid exchange, energy consumption size, reasonable structure are all to weigh the comprehensive important indicator of gas-liquid switching technology.Conventional gas-liquid switching technology mainly contains spray switching technology, impacts switching technology, centrifugal switching technology, streams switching technology, Venturi tube switching technology etc. at present.
Wherein, spray switching technology refers to liquid is able to fully, is discharged uniformly by sprinkling equipment, in liquid dispose procedure, carry the gas of grit through spray liquid region, carry out gas-liquid exchange with liquid, thereby the grit in gas is exchanged in liquid and discharged, realize gas cleaning.This gas-liquid switching technology is because gas-liquid exchange is very short time of contact, so exchange effect is limited, and spray equipment is set need to further takes up space, and sees that on the whole the volume of this gas-liquid exchange device is large, complex structure.
Impact switching technology, what mainly utilize is that gas enters the speed in gas-liquid exchange device, it requires gas after entering gas-liquid exchange device, to have enough speed can impact liquid level, thereby gas is entered in liquid, carries out sufficient gas-liquid exchange with liquid, and gas is purified.Because this switching technology has higher requirement for the dynamic property of gas, so it is larger to realize the energy consumption of this gas-liquid exchange.
Centrifugal switching technology, connects a cylindrical shell by power set and rotates, and inner barrel is equipped with axial drainage set, liquid can be drawn in cylindrical shell automatically, the top side face of cylindrical shell has fluid hole, and the liquid sucking is ejected in gas by fluid hole, transmits exchange with gas.Centrifugal switch need to be kept by power set the rotation of cylindrical shell, so it is larger equally to realize the energy consumption of this gas-liquid exchange.
Stream switching technology, for the certain requirement of being provided with of gas-liquid exchange device, in this device inside, a plurality of baffle plates need to be set, between described a plurality of baffle plate, form respectively a plurality of gas flow channels, thereby make the gas can turning movement in above-mentioned gas flow channel, in roundabout process, gas exchanges by the impact of liquid level is realized to gas-liquid.In liquid level being impacted to the process that realizes exchange, along with roundabout constantly carrying out, the dynamic property of gas is more and more lower, gas flow rates obviously reduces, do not have like this gas of dynamic property cannot liquid level be formed and be impacted when streaming to liquid level, so affected to a great extent the effect of gas-liquid exchange.
Venturi tube switching technology, the structure of gas-liquid exchange device that realizes Venturi tube switching technology by collapsible tube, trunnion and enlarged tube form, Venturi tube gas-liquid exchange principle is, flow direction along air-flow, first dusty gas enters collapsible tube, gas flow rate increases gradually along pipe, water erupts from trunnion, by high velocity air, clashed into and atomization, now gas is through the drop being erupted and the drop being atomized, in the process of passing, grit in gas contacts with drop and is lubricated, after gas enters enlarged tube, flow velocity reduces gradually, very easily bonding the becoming compared with large particle of grit after lubricated is more easily removed.Venturi tube gas-liquid exchange is one and by supersonic speed action principle, realizes liquid and excite the method that reaches gas-liquid switching purpose, also just because of its supersonic speed action principle, so the noise of Venturi tube gas-liquid exchange is very large, and must after gas being gradually reduced through collapsible tube, just can utilize trunnion to realize the eruption of liquid, realize gas-liquid exchange, therefore, venturi larynx two ends must maintain a very high pressure reduction, generally at tens thousand of handkerchiefs, energy consumption level is far away higher than conventional at present various switching technologies, and the scope of application is very limited.
But from the comprehensive important indicator of aforementioned measurement gas-liquid switching technology, above-mentioned traditional gas-liquid switching technology ubiquity energy consumption is large, volume is large, the defect of complex structure, gas-liquid exchange weak effect.
For above-mentioned traditional gas-liquid switching technology, the applicant has invented a kind of gas-liquid exchange device (see figure 1) based on gas throttling, and described gas-liquid exchange device comprises a chamber 1 that is marked with liquid, and described chamber 1 has air inlet 2 and gas outlet 3; Described gas-liquid heat exchanger chambers is straight shape chamber, and inside is fixedly installed a choke block 4, the passage that between the lower edge of described choke block 4 and the liquid level 5 of described choke block 4 place gas-liquid heat exchanger chambers, height of formation is H; Described height H is 20-200mm, and gas flow intensity is 2000-10000m
3/ h/m.The operation principle of above-mentioned gas-liquid exchange device is (see figure 2): gas enters described chamber interior through air inlet 2, the pressure of air inlet 2 one sides is P1, through gas outlet 3, the gas after gas-liquid exchange is discharged afterwards, in gas outlet, the pressure of 3 one sides is P2, P2<P1.Due to the existence of gas differential pressure, gas outlet 3 one sides can form the transition liquid level of a curve, and liquid level is poor is h.When air-flow passes through passage, due to the throttling action of choke block 4, flow velocity sharply increases, and changes direction sharp along transition liquid level, completes a gas-liquid exchange.
Above-mentioned gas-liquid exchange device is by the setting of choke block, realize throttling exchange, greatly reduce the energy consumption of gas-liquid exchange, but in this gas-liquid exchange device, choke block 4 is only set in gas-liquid heat exchanger chambers, throttling action by choke block 4 realizes gas and excites fast in the moment after choke block 4, drives liquid to excite simultaneously, thereby realizes gas-liquid exchange; Also just because of above-mentioned throttling action, making gas drive exciting of liquid is a process extremely fast, thereby has reduced gas and the time that liquid fully contacts and exchanges, and gas-liquid exchange efficiency is reduced; In addition, also due to what form under the throttling action at above-mentioned choke block 4, to exciting of gas, be a very fast process, reduced and in unit interval, carried out the amount of the gas of gas-liquid exchange, thereby make contacting of gas and liquid more insufficient, and then the efficiency of gas-liquid exchange is further reduced.
