Abstract

The invention discloses a movable biosafety type exhaust air efficient filtering device which comprises a box body, a filter, a scanning leak detection device, a circulating disinfection device, a draught fan and a control system. A control cavity and three sealing cavities are sequentially arranged in the box body from top to bottom. The control system is arranged in the control cavity, and the draught fan is electrically connected with the control system. The sealing cavities sequentially comprise a draught fan cavity, a leak detection cavity and a filtering cavity from top to bottom and arecorrespondingly provided with the draught fan, the scanning leak detection device and the filter. The circulating disinfection device communicates with the draught fan cavity and the filtering cavitythrough hoses. The draught fan cavity is provided with an air outlet, the filtering cavity is provided with an air inlet, and the filter communicates with the leak detection cavity. The draught fan communicates with the air outlet and the leak detection cavity. According to the movable biosafety type exhaust air efficient filtering device, through the filter, the scanning leak detection device, the circulating disinfection device, the draught fan and the control system, in-situ leak detection and disinfection, filter resistance detection and exhaust air rate detection functions of the filterare achieved, and the negative pressure exhaust air safety performance meeting the safety standard is achieved.

Description

technical field

[0001] The invention relates to the technical field of filtering equipment, in particular to a mobile biosafety exhaust high-efficiency filtering device. Background technique

[0002] With the outbreak of the global high-risk and highly contagious new crown pneumonia epidemic, scientific and reasonable epidemic prevention measures have been launched in various places. The existing mobile and portable negative pressure exhaust filter devices are usually composed of high-efficiency filters, fans, cabinets, and control systems. They do not have In-situ leak detection and disinfection of high-efficiency filters do not have the functions of filter resistance detection and exhaust air volume detection. Due to the above shortcomings, the installation of the filter frame cannot be judged, and there is a risk of pathogenic microorganisms (harmful aerosols) leaking due to unreasonable filter installation or damage to the filter frame sealing strip; there is no in-situ ...
