Divide the sidewall of flow container 200 to be respectively equipped with from top to bottom exhaust outlet 20 and phegma ozzle 30, be provided with the liquid seal device 40 (belonging to routine techniques) of overflow pipe in the bottom of point flow container 200.The fluid-tight of certain altitude (being generally set as 400～600mm in the present invention) simultaneously can also prevent thermal medium gas backflow (belonging to routine techniques) in tower.
Remarks explanation: this 400～600mm refers to overflow pipe and divides the tie point of flow container 200 to the distance of overflow pipe bottom.
Phegma ozzle 30 is connected with shell side outlet ozzle 7; Can discharge smoothly to ensure condensate liquid.Gas vent 50 is connected with shell side inlet nipple 6.
Plate journey inlet nipple 4 external cooling waters.
Operation principle following (as shown in Figure 8):
1, shell side runner:
Thermal medium (being tower overhead gas) in regenerator 300 rises at the bottom of tower, through lower resistance part (the regenerator autogamy in regenerator 300, belong to prior art, in Fig. 3, made drawing and omitted processing) rise to tower top, enter shell side inlet nipple 6 from gas vent 50;
Due to plate core group 2 a baffle 3 is each side set, therefore, gas can directly not flow to shell side outlet ozzle 7 along the inwall of cylinder shell 1, but by each plate to formed shell side runner 18 after, then gather to shell side outlet ozzle 7; The two-phase fluid of condensation flows out from shell side outlet ozzle 7; The two-phase fluid of this condensation flows in point flow container 200 from phegma ozzle 30;
2, plate journey runner:
Cooling water slave plate journey inlet nipple 4 flows in plate core group 2, enters respectively in the plate journey runner 17 of plate core group 2 after the shunting in medium inlet road 15, and the cooling water after intensification is finally collected rear slave plate journey outlet ozzle 5 by media outlet pipeline 16 and flowed out.
Remarks explanation: the cooling water of plate journey runner 17 and the tower overhead gas of shell side runner 18 form adverse current (wall-type heat exchange is carried out in the both sides at plate 11), take away latent heat and sensible heat that tower overhead gas discharges, congealing in tower overhead gas point is condensed into liquid state (being condensate liquid).In tower overhead gas, also containing some on-condensible gas, component is generally H
2s, COS, N
2, CO
2deng, be referred to as sour gas.Condensate liquid enters in point flow container 200 and separates with the two-phase fluid of sour gas composition.Condensate liquid is gravitate in point flow container 200, enters overflow pipe by condensate outlet, is back to the tower tray (for parts in tower disc type regenerator) in regenerator 300.Sour gas after gas-liquid separation, is expelled to torch from exhaust outlet 20.
Remarks explanation: torch is the common apparatus in petrochemical plant, purposes is discharge after chemical gases that some can be polluted atmosphere is burnt.
In order to ensure the reliability of solvent regeneration tower tower top condensing system, should make two media (tower overhead gas and cooling water) not contact, do not leak, equipment must seal closely.This condenser heat transfer element is titanium plate (being that plate 11 is titanium plate), thereby forms plate pair by the circumferential edges of fully-automatic laser welding medium import and export 13 and the circumferential edges of media outlet 14 between two plates 11; Plate between weld plate 11 by fully-automatic laser excircle finally form plate core group 2.The present invention, owing to using full-welding plate-type version, makes this condenser in performance heat-exchangers of the plate type efficient heat transfer performance, has ensured sealing property, has improved bearing capacity, and device security is reliable.
And traditional overhead condenser adopts shell-and-tube heat exchanger more, volume is large, and Heavy Weight cannot be arranged as one with regenerator, and independent bracket basis need to be set conventionally.And lamella heat exchanger of the present invention has that heat transfer efficiency is high, densification and the advantage such as lightweight, make it can be arranged in the top of regenerator 300, become one with regenerator 300, and do not need independent external supporting structure.
After testing, the heat transfer coefficient of lamella heat exchanger 100 of the present invention is 2～4 times of common tube shell heat exchanger.
Finally, it is also to be noted that, what more than enumerate is only several specific embodiments of the present invention.Obviously, the invention is not restricted to above embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention, all should think protection scope of the present invention.
