Problems solved by technology

[0004] However, in the original method, it is necessary to manually light the cigarette. After reaching a certain concentration, the unit must be turned on immediately.
All of these require people to operate in a clean room, which increases the time error of the self-cleaning test and increases human resources

Embodiment 1

[0034] see figure 1 , the present invention discloses a clean room self-cleaning time test device, characterized in that the test device comprises: an aerosol generator 1, a first pipeline 2, a nozzle 4, a nozzle 5, a sampling pump suction port 6, a sampling pump 7. Particle counter 8, calculation and control device 9, printer 10, workbench 11, second pipeline 12, data line 13, feedback data line 14, air conditioning valve 15;

[0035] The aerosol generator 1 is connected to the nozzle 5 through the first pipeline 2. The first pipeline 2 is a hollow aluminum tube with two telescopic nodes for automatic adjustment of its length. The nozzles 5 are uniformly arranged. The aerosol (particulate matter) generated by the aerosol generator 1 is transported to the nozzle 4 through the first pipeline 2, and then forms a static pressure in the nozzle 5, and is evenly sent into the room through the small holes on the nozzle 5, so that the dust-containing gas The sol is distributed evenly...

Abstract

The invention discloses a testing device and method for self-cleaning time of a cleaning room. The testing device comprises an aerosol generator, a first pipeline, a generating nozzle, a spraying head, a sampling pump suction opening, a sampling pump, a particle counter, a calculation and control device, a second pipeline, a data line, a feedback data line and an air conditioning valve. The aerosol generator is connected with the spraying head through the first pipeline, aerosol generated by the aerosol generator is conveyed to the generating nozzle through the first pipeline and then is sprayed, static pressure is generated in the spraying head, the aerosol is evenly fed into the cleaning room through small holes in the spraying head, the dusty aerosol is evenly fed into the cleaning room, the sampling pump suction opening is connected with the sampling pump, and the sampling pump, the particle counter and the calculation and control device are sequentially connected. The testing device and method for the self-cleaning time of the cleaning room well solve the problem of manual operation, avoid the influences of people on the particulate matter concentration in the cleaning room and meet the requirement for self-cleaning time testing of the unmanned cleaning room.

Description

technical field [0001] The invention belongs to the technical field of laboratory testing, and relates to a self-cleaning time testing device, in particular to a clean room self-cleaning time testing device; meanwhile, the invention also relates to a clean room self-cleaning time testing method. Background technique [0002] With the development of industry and the advancement of technology, in the past 20 years, with the continuous development, expansion and myth of the application of air cleaning technology, clean rooms have been widely used in environmental protection, medical treatment, pharmaceuticals, food, placement, agriculture and other industries. Especially in recent years, it has played an important role in my country's integrated circuit production, surgery and treatment care for special diseases, and as long as the industry. Therefore, the acceptance test after clean room design and construction is particularly important. [0003] In order to find out whether ...
