Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Figure 1 shows that the sectional view of gaseous effluent in the utility model specific embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be described in detail the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
As shown in Figure 1, gaseous effluent is that vertical structure is arranged, tube side medium is waste gas, and shell side medium is steam water interface.High-temp waste gas is introduced into entrance bobbin carriage 1, then carries out heat exchange by cooler bundle 12, and waste gas is reduced to after suitable temperature through heat exchange and discharges cooler by outlet bobbin carriage 15 through waste gas outlet 9.
Cooler casing 5 two ends are welded to connect with upper perforated plate 4 and lower perforated plate 8 respectively, and by upper perforated plate 4, lower perforated plate 8 respectively with entrance bobbin carriage 1 with export bobbin carriage 15 and be welded to connect, cooler bundle 12 is built in housing 5, and tube bank two ends are connected with upper and lower Tube-sheet Welding respectively.Entrance bobbin carriage 1 inwall and upper perforated plate 4 exhaust gas contact side are laid refractory liner 10 and are carried out thermal insulation.
Upper perforated plate 4 and lower perforated plate 8 all adopt flexible flat tube plate structure, namely between the plate part of tube sheet and cylindrical portions by circular sliding slopes, tube plate thickness is not more than 30mm, in order to the thermal expansion curve between absorption heat-exchange tube bank 12 and housing 5.
Cooler bundle adopts light pipe and screwed pipe combining form, adopt the whole steel pipe combination without splicing to form, top is light pipe portion 121, is in high exhaust temperatures section, bottom is threaded pipe section 122, account for the 1/3-1/2 of whole tube length, be in waste gas low-temperature zone, threaded pipe section 122 is by roll-in helix outside pipe, be corresponding spiral salient at tube wall, impel flow perturbation in pipe, reach strengthening low-temperature zone heat-transfer effect, reduce heat exchange area.Shell-side cylinder adopts reducing in two end portions.
Outside feedwater is introduced into import annular header 6, then enters cooler casing by the liquid inlet distributing pipe 7 between annular header and housing 5, more evenly enters heat-exchanging tube bundle 12 through feedwater distribution guide shell 14.Tube bank 12 is built in housing 5, in cooler casing 5, shell side medium washes away outside tube bank 12 by a kind of deflection plate 13 of disk-and-doughnut combining form successively, absorb the vaporization of waste gas liberated heat, annulus 131 and disk 132 are alternately fixed in tube bank 12 with certain spacing, shell side medium is forced along certain flow process by tube bank 12 by the stop of deflection plate, this baffle arrangement makes carbonated drink wash away heat-exchanging tube bundle more evenly fully, effectively can reduce and wash away dead band, reduce " waste stream ", heat-transfer effect is good, and resistance is little.
Shell side steam water interface forces carbonated drink to wash away even upper perforated plate 4 with specific flow velocity by carbonated drink guide shell 11, avoids upper perforated plate local overheating after arriving cooler upper end.After steam water interface has been heated, import outlet annular header 2 by the liquid-vapor mixture conduit 3 being distributed in housing 5 upper end, and then by completing whole water circulation in pipeline connecting system drum, output needs the steam of quality.
Effectively can be fallen the steel consumption of gaseous effluent equipment by the enforcement of above-mentioned means, reduce costs, whole circulation process resistance drop is less simultaneously, and security is high, namely improves the security reliability of system cloud gray model.
