Title: Acid feed treatment for controlling scale formation in evaporating and distilling plant
Inventor: GOELDNER RICHARD WARREN
IPC: C02F1/04
Filed: 1961-06-06
Abstract: 917,969. Preventing incrustation. AQUACHEMA Ine. June 6, 1961, No. 20358/61. Class 123 (1). Scale formation in a sea water evaporator wherein the water is boiled by the heat of compression of the generated vapour is prevented by injecting dilute hydrochloric acid into the evaporator feed chamber at a rate varying with the pressure difference across the vapour compressor, this pressure difference being indicative of the amount of scale present on the evaporator heat exchange surfaces. In the form shown the evaporator 10 consists of a cylindrical chamber containing a feed chamber 12, a heat exchange section 24 and a vapour collecting dome 18. Sea water enters the chamber 12 through a pipe 15 and flows upwardly in tubes 14 extending through the chamber 24 between tube plates 11, 13. The water is boiled in the tubes, the steam-water mixture being separated by impact with a baffle 19. Water returns to the chamber, 12 through a downcomer 16 whilst vapour is compressed and heated by a pump 21 and flows around the tubes 14 in the chamber 24 boiling the water in the tubes and itself condensing. The condensate is withdrawn for use through a pipe 25. The acid feed control consists of a pressure-sensitive switching device 36 which is connected by pipes 37, 38 to the chambers 18, 24 respectively, the device controlling a motor 30 driving a pump 29 which delivers acid through tubes 31 . . . 33 into the feed chamber. An increase in scaling of the tubes 14 decreases the amount of vapour being generated and the pressure differential across the control device 36 increases. The device then increases the rate of acid feed until the pressure differential returns to normal. A pH controller may be provided to stop the acid feed if the acid concentration in the evaporator reaches a level sufficient to cause corrosion thereof. The acid pump speed may be controlled manually from indications of a gauge 39.
