Embodiment Construction

[0012] The preferred embodiments of the cleaning device for Raschig rings of the present invention will be described in detail below in conjunction with the accompanying drawings, in order to further understand the technical scheme, purpose and beneficial effects of the invention.

[0013] figure 1 It is a three-dimensional schematic diagram of a cleaning device for Raschig rings in this embodiment. Please combine figure 2 , the cleaning device is surrounded by front, rear, left, right and bottom walls, and is in the shape of a cuboid. The right side of the cleaning device is provided with a cleaning tank 1, the depth of which is roughly half of the entire cleaning device, for placing the Raschig rings 8 to be cleaned. The cleaning tank 1 is surrounded by a vertical stop plate 12 , a horizontal bottom wall 10 , and part of the right and rear walls of the cleaning device. There are several leakage holes 11 on the bottom wall 10, and the shape of the leakage holes 11 can be ...

Abstract

The invention provides a cleaning device of a raschig ring. At present, no cleaning device specially used for a raschig ring occurs. The cleaning device supplied by the invention comprises a cleaning groove and a filter alternately arranged, wherein the cleaning groove is used for placing the raschig ring, and the filter is used for filtering waste water generated by cleaning; the depth of the cleaning groove is smaller than that of the cleaning device, and a plurality of holes smaller than the raschig ring are arranged on the cleaning groove. The cleaning device also comprises an overflowing plate positioned between the cleaning groove and the filter, wherein the height of the overflowing plate is smaller than that of the cleaning groove; the overflowing plate blocks the waste water flowing through the cleaning groove and blocks precipitated impurities; and the filter filters the waste water flowing over the overflowing plate. The cleaning device not only can be matched with a high pressure water gun to effectively clean dirt accumulated on the raschig ring, but also can filter the waste water and can recycle the waste water generated by cleaning, thereby saving water resources.

Description

technical field [0001] The invention relates to a cleaning device which can be used for cleaning Raschig rings in the semiconductor field. Background technique [0002] The manufacturing process of semiconductor products is complex and diverse, and the chemical substances used in the manufacturing process are quite diverse. In order to avoid the discharge of toxic waste gas into the air, the waste gas must be treated with a waste gas treatment system such as a scrubber before it is discharged. Whether it is a local scrubber at the machine end or a center scrubber at the plant end, most of them use packed wet scrubbers. [0003] In wet scrubbers, the part that carries the packing is the Raschig ring. After a period of use, a lot of dirt will accumulate on the Raschig ring. If it is not treated in time, it will affect the quality and efficiency of exhaust gas treatment. Therefore, the Raschig ring needs to be cleaned regularly. At present, there is no special device for cl...
