Background technology
At present, biogas condensation liquefaction equipment is general using shell and tube condensing plant conventional now.Traditional tube type cold
Condenser, all it is to condense steam in pipe by refrigerant heat convection outside pipe no matter using the tubulation of which kind of form.Steam is condensing
During, conduct oneself with dignity by the liquid of condensation, vacate position on heat exchange contact surface for steam, reach steam and continue to condense,
So as to realize effect that steam constantly condenses.But in Condensation, as condensate liquid is on the increase, condensate film increases
Thickness, the band that gas-liquid two-phase exchanges mixing can be formed on heat-transfer surface, heat exchange is prevented to a certain extent, under making heat transfer effect drastically
Drop.Then, increasing equipment is usually taken in technique, increases heat exchange area, or takes multistage steam condensation technology, centre is certainly
Take offence liquid isolation technics, concentrate aggregation condensation supercooling technical scheme, eliminate two phase flow.Or exchanged heat using short tube, reduce tube side,
Avoid long tube side from producing condensate liquid conjunctiva, improve heat transfer coefficient, strengthen condensation effect.These schemes be all pack as far as possible it is pure
Steam contacts with heat-transfer surface, eliminates two phase flow and produces.Expected Results is although reached using these schemes, but has also produced and set simultaneously

Specifically, because biogas main component is methane, its normal pressure condensing temperature is -162 DEG C.It is biogas liquefied in order to realize
And pooling function, all devices of the present invention are adiabatic using insulating.
The operation principle and workflow for the set row-tube type gas-liquid separation condenser that the present embodiment provides are as follows:
Purifying marsh gas to be liquefied enters from the air inlet of gas storehouse 9 that enters of point gas storehouse 2, and in air inlet under the driving of itself air pressure
By upper cover plate 41 and the circular hole of inner sleeve 22 in storehouse 9, enter in each inner sleeve 22;What the biogas of inner sleeve 22 was delivered up
Cooled down simultaneously, then by the top down of the outer tube 21 backflow further cooling of top seal, liquefaction;Simultaneously refrigerant from
The refrigerant import 15 of cooling storehouse 1 inputs, and is exported from refrigerant exit 14, so as to which the heat in cooling storehouse 1 be taken away, realizes outer tube
22nd, gas liquefaction in inner sleeve 21;Specifically, the refrigerant also compressed nitrogen, the biogas after liquefaction, in the top source of outer tube 21
In the presence of the promotion and deadweight of the biogas that source continually enters, flow downward, be cooled to -130 DEG C, and during flowing downward
Continue to liquefy, liquefied biogas and not liquefied cooling biogas, enter flow liquid storehouse 8 from the lower outlet of outer tube 21, then pass through
Fluid tube 43 enters in hydrops storehouse 3;In hydrops storehouse 3, liquefied biogas is gathered in the bottom of hydrops storehouse 3 under Gravitative Loads, and
Progressively flow to leakage choke tube 104 and fluid reservoir 10, and not liquefied cooling gas, pass through what the top sidewall of hydrops storehouse 3 was set
Gas returning port 31, the air inlet 5 into gas storehouse 9 is back to, goes successively to cooling liquid flow.The effect of leakage choke tube 104 is,
When liquid level rises to 3 upper limit liquid level of hydrops storehouse, liquid flows out from the ring flange 107 of the curved 104 pipe upper end of choke, enters by second
Liquid mouth 102 enters fluid reservoir 10.
