Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described, following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
The present embodiment provides a kind of solvent reclamation tower top built-in shell-and-plate condenser, comprises housing 1 and plate core body 6, and plate core body 6 is by stacked affixed rear formation of multiple heat exchange plates.Described heat exchange plate is sheet loop configuration, is processed with two circular holes on the ring surface of heat exchange plate, and described two circular holes are arranged in the bilateral symmetry of heat exchange plate inner circle.In the present embodiment, provide the version of two kinds of heat exchange plates, as shown in Figures 2 and 3.Heat exchange plate shown in Fig. 2 is corrugated plating, is distributed with arc fin at the surface uniform of heat exchange plate, forms corrugated.Heat exchange plate shown in Fig. 3 is fourth born of the same parents plates, the surface uniform of heat exchange plate be intervally distributed with ball impression of the same size and ball protruding, protruding and degree of depth ball impression of ball is 2～5 millimeters, diameter is 8～15 millimeters.
In the time that heat exchange plate is corrugated plating, the generation type of plate core body is: two heat exchange plates are coaxially placed, and respectively the circular hole of same position on two heat exchange plate ring surfaces is welded together, and forms plate pair; Then by multiple plates to coaxial placement, respectively right adjacent two plates inner circle and cylindrical are welded together, form plate core body 6.Between the centre bore of plate core body 6 and each plate centering two plates, passage forms shell side passage, the circular hole of plate core body 6 centre bore both sides and plate pair and plate between runner formation plate journey runner.
When heat exchange plate is fourth born of the same parents plates, the generation type of plate core body is: two heat exchange plates are coaxially placed, and makes the ball impression of two heat exchange plate opposite faces corresponding with ball impression, and ball is protruding protruding corresponding with ball.So on latter two heat exchange plate ring surface, the circular hole of same position welds together, and forms plate pair; Finally by multiple plates to coaxial placement, respectively right adjacent two plates inner circle and cylindrical are welded together, form plate core body 6.In the plate core body 6 forming, be ball impression corresponding with ball impression in the opposite face of any two adjacent plate, ball is protruding protruding corresponding with ball; As shown in Figure 4.Between the centre bore of plate core body 6 and each plate centering two plates, passage forms shell side passage, the circular hole of plate core body 6 centre bore both sides and plate pair and plate between runner formation plate journey runner.
The structure of housing 1 as shown in Figure 5, the column construction that housing 1 is hollow, plate core body 6 is coaxially fixedly mounted on housing 1 inside, the upper and lower surface of plate core body 6 is conflicted with the inner surface up and down of housing 1 respectively, for ensureing the isolation of plate journey runner and shell side runner, be positioned on the ring surface of plate core body 6 bottom heat exchange plates and do not process circular hole, make the sealed bottom of plate journey runner.The diameter of housing 1 is 2 times of plate core body 6 diameters, and the space forming between plate core body 6 outer circumference surfaces and housing 1 inner peripheral surface is thus gas-liquid separation space.Upper surface at housing 1: plate core body 6 centre bore positions coaxially process circular hole as tower overhead gas entrance 5, tower overhead gas entrance 5 connects with the shell side runner of plate core body 6; Ozzle of the each coaxial processing in position that plate core body 6 centre bore two mother rib lateral rotundums are corresponding, is used separately as recirculated water entrance 2 and circulating water outlet 4, and recirculated water entrance 2 and circulating water outlet 4 connect with the plate journey runner of plate core body 6.In two sour gas outlets 3 of upper surface processing of housing 1, the lower surface of housing 1 is processed with two condensate outlets 7 simultaneously, and described sour gas outlet and condensate outlet all connect with gas-liquid separation space.
When use, this condenser is directly installed on to the top in regenerator, and supports by the regenerator after reinforcing.Two condensate outlets of condenser bottom are connected with the two ends of T shape overflow pipe horizontal component respectively, as shown in Figure 1.Discharge opeing is the key that condensing plant can run well, if can not quick fluid-discharge, hydrops can flood part plate bundle, reduces effective heat transfer area of heat exchanger; For this reason, in the bottom of overflow pipe vertical portion, liquid seal device is set, to ensure that condensate liquid can discharge heat-exchange tube smoothly.The fluid-tight of certain altitude simultaneously can also prevent thermal medium gas backflow in tower.
The operation principle of this condenser is as shown in Fig. 1 and Fig. 6: in regenerator, thermal medium (being tower overhead gas) rises at the bottom of tower, rises to tower top through lower resistance part, enters the shell side runner of condenser from tower overhead gas entrance 5; Cold medium is cooling water, enters the plate journey runner of condenser from recirculated water entrance 2, flows out from circulating water outlet 4.The cooling water of plate journey runner and the tower overhead gas of shell side runner form cross-current, take away latent heat and sensible heat that tower overhead gas discharges, and it is condensate liquid that tower overhead gas is condensed into liquid state.The gas-liquid separation space of the two-phase fluid of condensation between plate core body 6 and housing 1 separates.Condensate liquid is gravitate in housing, enters overflow pipe by condensate outlet, is back to tower tray.Sour gas, after gas-liquid separation, is discharged from sour gas outlet 3.
In order to ensure the reliability of condenser, 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 heat exchange plate is titanium plate), between two plates, is welded and is formed plate core by fully-automatic laser.Use full-welding plate-type version, make this condenser in performance heat-exchangers of the plate type efficient heat transfer performance, ensured sealing property, improved bearing capacity, device security is reliable.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
