Abstract

The invention discloses a grains deprivation tower of non-kinetic fin tube, and relates to industrial dedusting equipment. The invention comprises the tower body, the frame or tube nest fasted in the tower, the upper and the lower wind doors and dedusting by-pass system. The dedusting tower has two basic types of tube nest paralleling the center axes of the tower or plumbing the center axes of the tower. The thermal pour tube in the tower has inner and outer fins. The non-kinetic natural recycle system of the air flow relates to make the high temperature air passing the tower and the outside low temperature air to form natural recycle, to cool the inner and the outer tube walls of the dedusting tower. The liquid containing absorbing grains deposit on the inner cooled wall under temperature difference and thermal pour effect. The invention has simple structure, low cost, high dedusting efficient, stable performance, and it can be used to large scale of dedusting equipment to solve the problem of hard deprivation of absorbing grains.

Description

technical field [0001] The invention relates to an industrial dedusting equipment. Specifically, the air with a higher temperature flowing through the dedusting tower is used to form a natural circulation with the cooler air outside to cool the inner and outer pipe walls of the dedusting tower, and the fluid containing inhalable particles When flowing in the tube, under the effect of temperature difference, the particles will be deposited on the cold wall surface of the tube due to the thermophoretic effect, which is a new type of industrial dust removal device for removing inhalable particles, which belongs to the field of dust removal technology or environmental protection technology field. Background technique [0002] Removing inhalable particulate matter (PM2.5) in the airflow is an international problem, and many existing dust removal equipment have little effect on the removal of such fine inhalable particulate matter (PM2.5). Thermophoresis is a hot topic of interna...
