A packed tower with anti-clogging and anti-wall flow

Abstract

The present invention discloses an anti-clogging and anti-wall-flow filler tower, which comprises a cylinder, a filler positioned in the cylinder, and a filler support grate positioned in the cylinder, wherein a liquid outlet is arranged below the cylinder and is connected to a finished product tank, a material inlet is arranged above the cylinder, the cylinder is provided with a gas outlet, a filler is arranged in the cylinder, the lower portion is the filler support grate, the cylinder is formed by sequentially connecting a first part, a second part and a third part from top to bottom, the second part has a cone table shape, the diameter of the lower end of the second part is larger than the diameter of the upper end, and the filler is positioned in the second part, and is stacked to form a cone table shape. According to the present invention, the anti-clogging and anti-wall-flow filler tower has characteristics of simple structure and convenient use; and when the high temperature gas passes through the cone-table-shaped cylinder, the speed is accelerated, such that the separation of the liquid at the wall surface is rapid, and the contact surface between the gas and the quid is large so as to completely contact.

Description

technical field [0001] The invention relates to a packed tower for preventing blockage and wall flow, and belongs to the technical field of chemical equipment. Background technique [0002] The packed tower is a kind of tower equipment, and the packing in the tower is used as the contact member between the gas-liquid two phases. The liquid enters from the top of the tower, is sprayed onto the filler through the liquid distributor, and contacts with the high-temperature gas rising from the bottom of the tower to achieve separation. The uniformity of liquid distribution in the packed tower is an important factor affecting the separation of the packed tower. It not only enhances the mass transfer performance of the packing, but also increases the uniformity of the liquid film thickness of the packing and improves the mass transfer effect of the packing tower. The existing spray liquid distributor mainly sprays liquid through each small distribution hole, and the flow rate at t...

Problems solved by technology

However, if the hole velocity is high, the diameter of the small hole is small. Since the pressure of the feed liquid is usually constant, the fine particles are easy to accumulate on the distribution orifice plate, which can easily block the small hole, affect the uniformity of liquid distribution, and reduce the separation efficiency.

At the same time, due to the large gap between the filler and the tower wall in the existing packed tower, the liquid tends to flow to the tower wall, resulting in wall flow phenomenon, which seriously affects mass transfer and heat transfer.
