Abstract

The invention discloses ventilation equipment for rail traffic. The ventilation equipment for rail traffic comprises a separation plate embedded into a wall, and a pair of exhaust fans is arranged inthe separation plate. A filtering screen is arranged at the ends, close to fan blades, of the exhaust fans. An air inlet pipe and an exhaust pipe are fixed to the two ends of the filtering screen. Oneend of the air inlet pipe communicates with an air source processor, and one end of the exhaust pipe communicates with the external air. The ventilation equipment for rail traffic solves the problemthat existing ventilation equipment is unsmooth in ventilation and large in cleaning difficulty.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a ventilation device for rail transit. Background technique [0002] Ventilation, also known as ventilation, is to send enough fresh air into the indoor space by mechanical or natural methods, and at the same time discharge the dirty air that does not meet the hygienic requirements, so that the indoor air can meet the hygienic requirements and the needs of the production process. The various facilities that complete the ventilation work in the building are collectively referred to as ventilation equipment, and ventilation can be divided into comprehensive ventilation and local ventilation according to the scope. General ventilation, also known as dilution ventilation, is the ventilation of the entire space. Local ventilation is to directly collect the polluted air at the place where the pollutants are generated and discharge it outdoors, or directly supply fresh air to the local space. L...
