摘要： The invention relates to a device and method for cleaning and drying work pieces in a treatment vessel (1) in which it is possible to produce a negative pressure. During the cleaning process, a liquid bath (50) is formed in the treatment vessel (1), said liquid bath surrounding the work pieces at least partially, and cleaning fluid and optionally a gaseous medium are introduced into the treatment vessel (1) under excess pressure via a spray unit (8a, 8b). The work piece support moves up and down or rotates so that the work pieces are subjected alternately to different cleaning processes in the liquid bath (50) and a gas chamber (52) situated above said liquid bath.

摘要： In the invention pickling process, steel and nickel or chromium alloys are pickled with an acidic pickling solution employing an oxidant, particularly hydrogen peroxide, and in which liquor is recirculated through inlets comprising a nozzle feeding liquor into a diffuser such that liquor is withdrawn from the bath and the volume of liquor flowing through the diffuser is a multiple of flow through the nozzle.
Steel or the alloys are pickled with an acidic solution containing iron and free hydrogen peroxide at a concentration of up to 0.1 gpl.
The process can operate effectively at a free fluoride concentration of from 20 to 30 gpl and a sulphuric acid concentration of from 80 to 110 gpl.
The lifetime of the bath before it needs to be replaced can be lengthened by the process compared with using an air agitation system摘要翻译： 在本发明酸洗方法中，使用氧化剂，特别是过氧化氢的酸性酸洗溶液酸洗钢和镍或铬合金，并且其中液体通过包括喷嘴的入口再循环到扩散器中，使得液体从 浴和流过扩散器的液体的体积是通过喷嘴流动的倍数。 钢或合金用浓度高达0.1gpl的铁和游离过氧化氢的酸性溶液酸洗。 该方法可以在20至30gp1的自由氟化物浓度和80至110gp1的硫酸浓度下有效地操作。 与使用空气搅拌系统相比，浴前需要更换的寿命可以延长。

摘要： The present invention provides a method of and an apparatus for efficiently and economically discharging solid particles, which have sedimented on the bottom of a tank, out from the tank. A liquid is ejected from an ejector installed in the tank to move the sedimented solid particles to a predetermined place from which the sedimented solid particles are discharged out from the tank. Further, a solution which contains sedimentary solid particles is cooled and the solid particles are efficiently separated by a solid-liquid separator.
