Adsorption tower

Abstract

The invention discloses an adsorption tower. The adsorption tower comprises a ventilation head, a spherical cap-shaped pore plate, a filtration blocking layer, a central press ring, a side press ring and an air inlet pipe. The ventilation head is connected to the air inlet pipe of the adsorption tower. The filtration blocking layer is fixed on the spherical cap-shaped pore plate by the side press ring and the central press ring. The adsorption tower can realize uniform distribution of an air-flow in the adsorption tower, can reduce air-flow impact, can realize full utilization of a filling material in the adsorption tower, and has greatly reduced whole height and low adsorption tower installation place requirements.

Description

technical field [0001] The invention relates to an adsorption device, in particular to an adsorption tower. Background technique [0002] Such as figure 1 As shown, the existing adsorption tower device includes a tower bottom 1, an orifice plate 2 and an adsorption tower 3. The airflow enters from the tower bottom 1, enters the adsorption tower 3 through the flat orifice plate 2, and the packing 4 is located in the adsorption tower 3. Although the structure of the existing adsorption tower is simple, easy to process and assemble, there are three problems: the first problem is that a large amount of "dead space" is left, because the gas enters the bottom cavity at a certain flow rate, and the air flow is high-speed and straight-line. The way of movement flows through the bottom packing, which does not diverge and distribute in time, so that the edge part of the lower packing layer will not be in sufficient contact with the air flow, and at the same time, the gas flow rate fl...

Problems solved by technology

Although the structure of the existing adsorption tower is simple and easy to process and assemble, there are three problems: the first problem is that a large amount of "dead space" is left, because the gas enters the bottom cavity at a certain flow rate, and the air flow is high-speed and straight-line. The way of movement flowing through the bottom packing does not get divergence and distribution in time, so the edge part of the lower packing layer will not be in sufficient contact with the air flow, and at the same time, the gas flow rate flowing through the middle packing layer will be too fast, which will affect the use effect of the packing The second problem is that due to the concentrated airflow impacting the middle of the packing layer, the wear of the center packing layer is aggravated, and after the center packing is worn, it will cause gaps and the displacement of the packing layer, resulting in more serious wear and impact, and even the packing boils effect, which leads to the performance degradation or even failure of the packing; the third problem is that since the air flow is bottom air intake, it is inevitable to install guide pipes, flanges and other parts at the bottom of the container. In order to facilitate installation and maintenance, it is necessary to reserve installation Maintenance space, resulting in an increase in the height of the entire container, especially in some height-sensitive occasions, this aspect is more prominent
