Spiral step falling distribution type separating tower column plate

Abstract

A separating tower plate in the type of helix steps down distribution, is an annular tower plate got from a whole traditional round tower plate after cutting a round of 1 / 25 to 1 / 4 of the area along the center. And then the annular tower plate is separated into n parts, wherein n is equal to 3 to 10, to get fan-shaped tower plates, which are mounted on the support pipe throughout the center of the separating tower in the type of helix steps down distribution. The total height between tower plates of a complete alternation circle is equivalent to the fixed height between plates of traditional tower. The adjacent two fan-shaped tower plates are connected by radial baffle, upper of which is higher than the former fan-shaped tower plate to form a liquid overflow weir. There are gas-liquid contacting components such as float valve, sieve pore or bubble cap and so on. The advantage of the separating tower plate in the type of helix steps down distribution of the invention resides that the utilization factor of the tower plate area is higher because whole or most liquid-falling area and liquid-accepting area are omitted, and resides that heat transfer and mass transfer between gas and liquid are more sufficiency because the liquid flows a longer way when flowing down a section tower height on the helix plate.

Description

field of invention [0001] The invention relates to a core part of a tray type separation tower - a tray. Background technique [0002] In the industrial production process of chemical industry, petrochemical industry and oil refining, it is often necessary to use a plate separation tower, also known as a plate separation tower, which is used to process various gas phase mixtures and liquid phase mixtures to achieve separation and purification. the goal of. There are also many types of plate separation towers, which are mainly divided according to the type of trays. The tray is the core of the plate separation tower, and it is the place where the gas-liquid contact conducts heat transfer and mass transfer; It is composed of liquid pan, overflow weir, downcomer, tray support and fasteners; according to the structural characteristics, it can be divided into two types: integral type and block type. Tray towers have been used for more than 100 years, and still occupy a very im...

Problems solved by technology

However, because the traditional tray needs to be equipped with structures such as liquid receiving trays and downcomers, it needs to occupy a part of the tray, and at the same time consider the flow of gas and liquid, so that the effective use area of ​​the entire tray is greatly reduced; the through-flow tray Although the downcomer is omitted, its efficiency and operating flexibility are poor
