Embodiment
As shown in Figure 1 and Figure 2, the present invention is made up of pipeline and water cooler, inlet manifold 1 be in charge of with main air inlet respectively 3 and air inlet for subsequent use be in charge of 4 and be connected, main air inlet is in charge of 3 and is connected with split water cooler, split water cooler is by air charge cooler 7 and go out Gas Cooler 9 and form, main air inlet is in charge of 3 and is first connected with air charge cooler 7, and the cooling escape pipe 8 of air charge cooler 7 is connected with the cooling inlet pipe 17 going out Gas Cooler 9, goes out Gas Cooler 9 and is in charge of 5 is connected with main giving vent to anger; Air inlet for subsequent use is in charge of 4 and is connected with water cooler 10 for subsequent use, and water cooler 10 for subsequent use is in charge of 6 is connected with for subsequent use being given vent to anger; Main giving vent to anger is in charge of 5 and is in charge of 6 is connected with the house steward 2 that gives vent to anger respectively with for subsequent use giving vent to anger.Be provided with air outlet 13 giving vent to anger on house steward 2, giving vent to anger, the two ends of air outlet 13 on house steward 2 are respectively arranged with main valve 14 and auxiliary-valve 15, main valve 14 controls the cooling gas from going out Gas Cooler 9 and discharging to air outlet 13, and auxiliary-valve 15 controls the cooling gas of discharging to air outlet 13 from water cooler 10 for subsequent use.The material of the described house steward of giving vent to anger 2 is tetrafluoroethylene, and the material of described main valve 14 and auxiliary-valve 15 is tetrafluoroethylene.As depicted in figs. 3 and 5, the base plate of air charge cooler 7 is arranged to air inlet inclined floor 11, and air inlet inclined floor 11 becomes a pitch angle ɑ 12 with horizontal plane, pitch angle ɑ 12 is 10-20o; The base plate going out Gas Cooler 9 is identical with the air inlet inclined floor 11 of air charge cooler 7, be arranged to inclined floor of giving vent to anger equally, inclined floor of giving vent to anger becomes a pitch angle ɑ 12 with horizontal plane, pitch angle ɑ 12 is 10-20o, and the direction of inclination is consistent with the air inlet inclined floor 11 of air charge cooler 7.
The present invention is work like this: in normal operation, close auxiliary-valve 15, high temperature sulfur dioxide gas enters from inlet manifold 1, being in charge of 3 from main air inlet enters air charge cooler 7, and enter tubulation 15, as shown in Figure 4, tubulation 15 is distributed in the inner chamber of water cooler, heat-eliminating medium outside tubulation 15, high temperature sulfur dioxide gas is cooled in tubulation 15, the temperature being in charge of the sulfur dioxide gas that 3 enter from main air inlet is 250-300 DEG C, in tubulation 15 after cooling, temperature reduces, cooled sulfur dioxide gas enters out Gas Cooler 9 from the bottom of air charge cooler 7 through overcooling escape pipe 8, the internal structure going out Gas Cooler 9 is identical with air charge cooler 7, cooled further going out in Gas Cooler 9 through the sulfur dioxide gas that enters of cooling escape pipe 8, and be in charge of 5 discharge from main giving vent to anger to the house steward 2 that gives vent to anger, the temperature of the sulfur dioxide gas of now discharging is down to 70-80 DEG C, be suitable as the finings of sugarcane press juice.In working order, air charge cooler 7 and the bottom going out Gas Cooler 9, all pile up the sulfurous acid having and produce in process of cooling, sulfurous acid has corrodibility, produces corrosive nature to the metal of water cooler, as discharged not in time, to the metal bottom seriously corroded of water cooler, corrosion speed is surprising, therefore, timing discharge operation in the course of the work, makes sulfurous acid discharge from air inlet inclined floor 11 and inclined floor of giving vent to anger in time.
In the stand-by state, close main valve 14, namely high temperature sulfur dioxide gas is in charge of 4 enters water cooler 10 for subsequent use from for subsequent use being given vent to anger, and is cooled in tubulation in water cooler 10 inner chamber for subsequent use, is in charge of 6 discharged to the house steward 2 that gives vent to anger from for subsequent use giving vent to anger.
Under inspecting state, close main valve 14 and auxiliary-valve 15, under the negative pressure state of inlet manifold 1, very easily block and be in charge of 3 sulfur dioxide gas out from main air inlet, convenient to air charge cooler 7, the maintenance going out Gas Cooler 9 and whole pipeline.
