Heating device for gas filtration system

Abstract

The invention discloses a heating device for a gas filtering system; the heating device comprises a fully-enclosed casing for surrounding the gas filtering system, a heating piece disposed in the casing, and a bracket disposed at the lower end of the casing for adjusting the height of the casing; the upper end and the lower end of the casing are provided with through holes for passage of pipes ofthe gas filtration system, the casing includes left and right casing portions that are abutted and detachable; the bracket is coupled to the casing by a rotating mechanism; and the heating piece is electrically connected to an external power source through a power source line. The heating device has the beneficial effects that the difference of gas temperature inside and outside the gas filteringsystem is reduced, so that a gas cannot be condensed in the entire gas filtering system, smooth discharge of water vapor in the gas can be ensured, phenomenon of condensed water produced from a low temperature and low velocity gas in the gas filtering system can be prevented, and the normal use of a gas filter can be ensured.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating device for a gas filtering system. Background technique [0002] Disposable flexible culture bags are more and more used in bioreactors. A gas filter will be placed at the gas outlet of the culture bag to prevent the external environment from polluting the bag. At the same time, the gas with a certain temperature and moisture in the bag Out of the bag through the gas filter. The working environment temperature of disposable bioreactors is generally lower than 30°C. Under the conditions of GMP workshops, the ambient temperature range is 18-26°C. For cost considerations, disposable bioreactors can also be used in ordinary non-air-conditioned conditions. It is used in the laboratory, so the ambient temperature range becomes larger, generally 5 ~ 30 ℃, which puts forward higher requirements for the gas filter at the gas outlet of the culture bag, and it is necessary to ensure the smooth...
