Radial flow type air separation purifier

Abstract

The invention discloses a radial flow type air purifier which comprises activated alumina fillers and molecular sieve fillers arranged in a cylinder; the radial flow type air purifier is characterized by adopting multi-layer independent airflow channels; each airflow channel adopts a radial flow type circular structure; both the activated alumina fillers and the molecular sieve fillers adopt multi-layer circular structures. According to the radial flow type air purifier disclosed by the invention, the airflow channels adopt radial flow type structures, so that flow resistance is reduced greatly; the purifier is provided with multi-layer alumina, molecular sieve filler layers and the multi-layer independent airflow channels, therefore, an adsorption area is increased greatly, height of the purifier is decreased, and an air flow condition is improved; each of the independent airflow channels is configured with an air flow equalizing structure, thus equalizing air flow well; and a bi-directional self-tightening sealing layer at the tail end of a filling tube can prevent air leakage effectively. Because of a structural advantage, the radial flow type air purifier can well satisfy demands on air purification of large-scale and ultra-large-scale air separation systems.

Description

technical field [0001] The invention belongs to the field of gas purification, and relates to an adsorber mainly used for absorbing impurities such as carbon dioxide, water vapor and acetylene in the air, specifically a radial flow air separation purifier. Background technique [0002] With the continuous development of the scale and technology of large-scale iron and steel smelting, large-scale petrochemical, and large-scale coal chemical projects, the demand for air separation systems is also increasing. In order to meet this demand and achieve the purpose of energy saving and emission reduction, the current air separation field We are researching and manufacturing the largest air separation unit which has reached 100,000-120,000 Nm 3 / h scale. The sharp increase in the scale of the air separation plant has also put forward higher requirements for the scale of its key components. The air separation purifier is the core equipment for removing impurities in the air. Its ai...

Problems solved by technology

However, for large and ultra-large air separation systems, traditional radial purifiers still face problems such as sharp increase in volume, height increase, difficulty in uniform air flow, and uneven adsorption.

It can be seen that further improving the structure of the purifier, and then solving the problems of large area occupied by the purifier, increased height, insufficient adsorption uniformity, and difficult transportation, has become an important task to be carried out in the field of air separation.
