Definitions
- the present invention relates to a method for cleaning valves or lines through the hydrolysable polymers are promoted at operating temperature.
- Hydrolyzable polymers are thermoplastic polyesters, polyamides or polycarbonates, such as polyethylene, polypropylene or polybutylene terephthalate or naphthalate, polyamide 6 or -6.6, poly (bisphenol A carbonate) or copolymers thereof.
- the object of the present invention is to demonstrate a method which enables the cleaning of valves or lines for hydrolyzable polymers, the cleaning being carried out as far as possible in the installed state without major assembly work.
- This object is achieved according to the invention by a process of the type mentioned, which is characterized in that after the polymer stream has been shut off and the polymer has been emptied as far as possible, while maintaining the operating temperature plus / minus 10 ° C. steam is passed through the valves or lines to be cleaned is, the supply of the steam takes place via hydrolysis valves embedded in the wall of the valve housing or the lines and the discharge takes place via drainage openings.
- the invention is based on the knowledge that the polymers mentioned at the outset can be hydrolyzed with water vapor at a high temperature in the range from about 120 to 350.degree. Since the operating temperature of the polymer valves or lines is in the same range, one is separate temperature setting is not required. It is sufficient not to interrupt the normal heating of the valves or lines, usually a jacket heating by means of heat transfer fluid, whereby a temperature which is approximately equal to the operating temperature plus / minus 10 ° C is established automatically. The amount of steam required is low. The amount of steam is preferably kept just large enough that the product line is not cooled but the hydrolysis is maintained.
- 6 bar steam which is usually available anyway in production plants, can be used after appropriate expansion, preferably down to 1-2 bar absolute, particularly preferably 1.0-1.3 bar.
- a mixture of water vapor and the vapor of a monomer on which the polymer is based for example ethylene glycol or diethylene glycol in the case of polyethylene terephthalate, can also be used.
- Safety (flammability) and environmental (waste water) can also be used.
- hydrolysis is preferably carried out in the absence of oxygen. Depending on the polymer, the presence of oxygen can also be tolerated or even desirable (hydrolytic-oxidative decomposition).
- the hydrolysis products i.e. H. the cleavage products of the polymer, such as oligomers, monomers and their decomposition products, are discharged in part together with the water vapor and in part together with the condensate via an emptying opening.
- the ventilation openings which are usually present anyway, are suitable as discharge openings
- Drainage devices such as valves or lockable lines.
- the emptying nozzle is expediently located in the polymer line extending from the valve. The steam feed is continued until the condensate of the emerging steam is free of hydrolytic degradation products of the
- FIG. 2 which shows a hydrolysis valve of Fig. 1 in detail
- Fig. 1 shows an example of a change he distribute for polymer melts.
- This essentially consists of the distribution space (1) connected to the product line (2) and two mutually operated product valves (3).
- Each product valve (3) consists of a housing (4) designed as a guide cylinder with a housing extension (5) on the side opposite the branch of the product line (6) and a valve piston (7) with a valve head (8) that can move in the axial direction in the guide cylinder. , which engages in the closed valve position in the valve seat (9), and a mushroom-shaped valve head attachment (11).
- the polymer melt flows from the product line (2), after directing the flow through the mushroom-shaped attachment (11), to the open product valve (3), here the left valve, and finally to the product line (6).
- a valve seat is embedded in the housing wall of the product valve (3), for example opposite the branching of the product line (6), in the valve (3) shown here in the area of the housing extension (5), into which the valve head of the valve is closed when the valve position is closed engages the connecting piece (14) with the heat transfer fluid-heated hydrolysis valve (10).
- steam preferably water vapor
- the steam flows around the valve piston (7) to the valve seat (9) and passes through the product line (6) and a ventilation and not shown here
- Fig. 2 shows the structure of the hydrolysis valve (10) of Fig. 1 in detail.
- the hydrolysis valve (10) essentially consists of the housing (17), which is designed as a guide cylinder and heated via the heating jacket (16), and the piston (18), the head of which is axially movable therein (19) engages in the valve seat (24) with the elongated opening cone (22) in the closed position.
- the steam is supplied via the connector (15) embedded in the housing wall (17).
- the valve head (19) carries an attachment (20) which is designed such that when the hydrolysis valve (10) is closed, the wall (4) of the product valve (3) has no dead space at the connection point.
- the valve head cap (20) is flush with the inner surface of the housing wall (4).
- the hydrolysis valve (10) can in the same way, as shown here using the example of a product valve (3), in the wall of a
