Problems solved by technology

However, due to the weak corrosion resistance of metals, especially the mass transfer of strong acidic substances, it is usually necessary to stop the machine to replace the packing after two or three months of use, which brings huge losses to the enterprise.

Embodiment Construction

[0084] The present invention will be further explained below in conjunction with the accompanying drawings.

[0085] This specific embodiment is only an explanation of the present invention and not a limitation of the present invention. Any changes made by those skilled in the art after reading the description of the present invention will be subject to the protection of the patent law as long as they are within the protection scope of the claims. Protect.

[0086] Such as Figure 1-2 As shown, the polytetrafluoroethylene corrugated plate is made of polytetrafluoroethylene regenerated powder through extrusion molding into a pipe, and then the pipe is turned to make; the pipe wall thickness of the pipe is the thickness of the corrugated plate, and the The body of the polytetrafluoroethylene corrugated board 10 has corrugations 101 regularly arranged at regular intervals with upward bulges and downward depressions, and several evenly distributed through holes 102; The included...

Abstract

The invention relates to a teflon corrugated plate assembly and belongs to the technical field of a structured packing. The teflon corrugated plate assembly comprises an assembly body and a fixation structure of the assembly body. The assembly body is formed by overlapping several teflon corrugated plates through a mode of contacting peaks and peak points. Thus, the assembly body has a mass transfer section. The fixation structure is a hot-melt binding structure formed by letting a teflon hot melt tube pass through a binder hole of the assembly body and hot-pressing two ends. The corrugated plate provided by the invention can replace a metal corrugated plate in the prior art and is the basis for forming a teflon structured packing. As teflon has ultra-strong corrosion resistance, by the use of the teflon structured packing, downtime can be effectively prolonged, and it can be usually guaranteed that update is not required within three years. The teflon corrugated plate assembly has remarkable economic benefit.

Description

technical field [0001] The invention relates to a corrugated board component filler, in particular to a polytetrafluoroethylene corrugated board component and a manufacturing method thereof. It belongs to the technical field of structured packing. Background technique [0002] Fillers generally refer to materials that are filled in other objects. In chemical engineering, packing refers to the inert solid material installed in the packed tower, its function is to increase the contact surface of gas-liquid, so that they are strongly mixed with each other. There are two kinds of dispersed packing and structured packing. Dispersed fillers such as Pall rings and Raschig rings. Structured packing is a packing that is arranged in a certain geometric configuration and stacked neatly. There are many types of structured packing, which can be divided into grid packing, corrugated packing, pulse packing and so on according to their geometric structure. The corrugated packing is a d...
