Industrial automation control cabinet dustproof and anti-corrosion ventilation system and method

Abstract

The present invention provides an industrial automation control cabinet dustproof and anti-corrosion ventilation system and method. The system comprises: air inlet units (an air inlet module, a dust filtering module, an internal and external circulation module, an electrostatic dust collection module, an activated carbon adsorption module, a fan module, a temperature collection module and a singlechip microcomputer control module), and an air inlet unit (an air outlet module). The temperature in a control cabinet is determined through temperature sensing, internal and external circulation ventilation modes are selected, more than 99.9% tiny dust or harmful particles are removed by the electrostatic dust collection module through the dust filtering module in the air required being ventilated or in a purification cabinet, and enter the activated carbon adsorption module to absorb chemical gases, and the fan is employed to drive the air with high cleanness to enter the control cabinet tocomplete ventilation and circulation. The ventilation problem of the automation control cabinet installed indoors and outdoors in a work environment with poor conditions, a large dust concentration or having few of chemical corrosive gases in the industries such as metallurgy, buildings, petro-chemical and cement is solved.

Description

technical field [0001] The invention relates to an anti-corrosion ventilation system, in particular to a dust-proof and anti-corrosion ventilation system and method for an industrial automation control cabinet.

AI Technical Summary

Problems solved by technology

The cabinets of industrial automation control cabinets are generally treated with anti-corrosion, airtight or explosion-proof treatment. However, due to the limitation of the external dust environment, the traditional sealed cabinets cannot effectively ventilate and dissipate heat with the outside world, resulting in long operating hours of the components in the cabinet. prone to overheating and failure

[0004] The existing method usually directly installs the fan to supply air in the opening of the cabinet without any protective measures, or simply installs a dust-proof board, but the method with only simple protective measures is no longer competent for the complex anti-corrosion protection of the existing industrial automation control cabinets. Due to the development needs of dust and anti-corrosion ventilation, it is impossible to protect fine particles or chemical gases, especially carbon powder particles in industrial dust or corrosive chemical gases, which seriously endanger the normal, stable and reliable work and service life of automation equipment.
