Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1, Fig. 2.
A kind of converted starch vacuum pipe cleaning systems, comprise the vavuum pump 2 be connected with vacuum reaction still 1, a condenser 3 is provided with between described vacuum reaction still 1 and vavuum pump 2, described condenser 3 is an external circulating water pipeline 4 also, the hypomere pipeline of circulating water pipeline 4 is also provided with a buffer bin 5, the external fumer 6 of described vacuum delivery side of pump, it is characterized in that: also comprise a pipe blow-through 7, described pipe blow-through 7 comprises the scavenging pump 8 being arranged at condenser 3 outside, described scavenging pump 8 is communicated with the interface 15 that vacuumizes on the top of vacuum reaction still 1, the bottom of vacuum reaction still 1 is communicated with filtering ponds 9 by the pipeline of pipe blow-through 7, being communicated with the water tank of condenser 3 by the arm 10 being parallel to vavuum pump 2 of filtering ponds.
Starch and chemical solutions are heated in vacuum reaction still 1, along with the temperature of reactant constantly raises, moisture in reactant constantly evaporates, the temperature of steam also constantly raises, vavuum pump 2 pairs of vacuum reaction stills 1 vacuumize, by condenser 3 condensation, steam becomes aqueous water and flows into buffer bin 5, and other gases are discharged by the blast pipe 18 of vacuum pipe from fumer 6.Vacuum reaction still 1 vacuumize interface 15, condenser 3, vavuum pump 2, fumer 6, this pipeline of blast pipe 8, owing to being subject to the gas attack containing acid mist for a long time, and have a small amount of gelatinized corn starch, therefore, the utility model peripheral hardware pipe blow-through 7, when vacuum reaction kettle for reaction is complete, when needing to clean vacuum pipe, close vavuum pump 2, the water tank of condenser 3 is injected a certain amount of water simultaneously, and entered water, the gate valve of draining is all closed, gate valve between vavuum pump 2 and fumer is also closed, open scavenging pump 8, then water condenser 3, vacuum reaction still 1, filtering ponds 9, arm 10, get back to condenser 3, form a complete circulation, not only can external pipeline be cleaned, also can clean vacuum reaction still inside.
