Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Referring to Fig. 1, the dry method process hides heat pump steam supply heater that this utility model provides, including live steam pipeline, cooled-air line, and for the first paragraph of baking oven heat supply after respectively first, second and third coating head, second segment and the 3rd section；Described first paragraph, second segment and the 3rd section all include heat exchanger and flash tank, and heat exchanger each section interior is all connected with live steam pipeline and cooled-air line；The condensation-water drain of heat exchanger each section interior is connected with the condensing water inlet of flash tank, and the indirect steam outlet of flash tank is connected with the indirect steam entrance of heat exchanger in this section by heat pump.In each section, heat pump 12 is all connected with live steam pipeline.Pipeline between described heat exchanger and flash tank is additionally provided with drain valve 7.In described each section, flash tank is all connected with condensate water pot 9, and the pipeline between described each flash tank and condensate water pot 9 is provided with automatic regulating valve 8.The pipeline that in each section, heat exchanger is connected with live steam pipeline is provided with check-valves 11.Described condensate water pot 9 is connected to surface condenser 10.Described condensate water pot 9 is provided by the pipeline of condensate pump and is connected with rear finishing workshop section.Heat exchanger adopts finned tube exchanger.
At first paragraph, enter 1# flash tank 4 from the condensed water of 1# finned tube exchanger 1 condensation and carry out flash distillation, the reuse after heat pump 12 is by a part of live steam injection supercharging of indirect steam after flash distillation uses to this section of 1# finned tube exchanger 1, it addition, need to pass into live steam in 1# finned tube exchanger 1 when temperature does not reach dry requirement to carry out supplementary heating；Cold air is heated into hot blast by 1# finned tube exchanger 1, and hot blast is passed into first baking oven (relatively low section of temperature) of the first coating head 15 and coating is dried, and the condensed water in 1# flash tank 4 flows into condensate pipe, finally enters condensate water pot 9；The indirect steam of same second segment passes into second segment 2# finned tube exchanger 2 and cold air is heated into hot blast, when indirect steam temperature does not reach heating requirements, filling is carried out by live steam, hot blast is passed into second baking oven (middle-temperature section) of the second coating head and coating is dried, and makes solvent volatilize.Enter 2# flash tank 5 from the condensed water of 2# finned tube exchanger 2 condensation and carry out flash distillation, the reuse after heat pump is by a part of live steam injection supercharging of indirect steam after flash distillation uses to 2# finned tube exchanger 2, in 2# flash tank 5, remaining condensed water flows into condensate pipe, finally enters condensate water pot 9；The indirect steam of the 3rd section passes into this section of 3# finned tube exchanger 3 and cold air is heated into hot blast, when indirect steam temperature does not reach heating requirements, filling is carried out by live steam, hot blast is passed into the 3rd baking oven (temperature upper sector) of the 3rd coating head and coating is dried, enter 3# flash tank 6 from the condensed water of 3# finned tube exchanger 3 condensation and carry out flash distillation, the reuse after heat pump 12 is by a part of live steam injection supercharging of indirect steam after flash distillation uses to 3# heat exchanger 3, and in 3# flash tank 6, remaining condensed water flows directly into condensate water pot 9；And the condensed water in condensate water pot 9 is finally pumped into rear finishing workshop section by condensate pump and carries out reuse.Surface condenser 10 delivered to by the condensate pump of condensate water pot 9 simultaneously, and hot water is also given rear fin-ishing stages after being heated by surface condenser 10 and utilized by cooling water.Condensate water pot can also be played the effect of blood pressure lowering.
As in figure 2 it is shown, hot-air is respectively fed to baking oven through blower fan, air channel, it is generally 2～3 baking ovens below in each coating head 15.Hot blast blows in release paper or the base fabric of coating so that it is on Polyurethane resin slurry solvent volatilization and film forming.Temperature in baking oven should be distributed by low temperature to high temperature, owing to every section itself also has the only small temperature difference, so being all lead to back to front when hot blast leads to baking oven.After slurry is coated with, when having just enter into baking oven, temperature should lower than the boiling temperature of low boiling point solvent in mixed solvent so that it is slowly volatilizees, then steps up temperature, makes the high-boiling fration in solvent also begin to volatilization, finally makes residual solvent volatilization clean.Generally, the temperature of every section of baking oven raises along with increasing of coating head, and along with the temperature difference between the difference every section of synthetic leather kind also can be different.So different phase should supply the steam of different grade, meet the baking temperature change required by this technique.
In baking oven, hot blast arrives synthetic leather by upper and lower nozzle in baking oven.
