Description
Technical field
The present invention relates to performance of precipitator detection field, in particular to a kind of dust aerosol generator setting and sending out dirt quality.
Background technology
Along with the attention degree of elimination of dust contamination is deepened by country, domestic many environmental protection equipments design production unit is all developing various types of cleaner units.In the process of performance of precipitator detection, powder amount is stablized and adjustable powder producer is the key factor in dust collector efficiency detection, but, it is difficult in the market find a kind of dust aerosol generator setting and sending out dirt quality.
The Chinese invention patent that application number is " propelled dust aerosol generating equipment " by name of 201110054352.1 describes the technical scheme that a kind of use is similar to the propeller control dust powder amount of syringe-like, the propeller that the program uses cannot use continuously, is only used for a small amount of dust and tests.
Application number is that the Chinese utility model patent of by name " a kind of dust generator " of 201320205310.8 provides and a kind of uses setting gauge to control the scheme of the size of dust powder amount, the dust of compacting is dialled in discharging opening by being arranged on the material poking fork rotation of discharging opening upper end by the program, dust falls to step band conveyer device, then in dust recycling device.During practical application, dust has certain mobility, simple stir the dust of compacting by material poking fork and enter in discharging opening, dust can be toggled it to other positions by atwirl material poking fork and cannot completely in discharging opening, the dust of discharging opening cannot be accurately controlled by such setting.Additionally Timing Belt conveyer device also cannot ensure the continuous feeding of dust recycling device.
The Chinese invention patent that application number is " toothed belt type aerosol generation equipment " by name of 201110047698.9 provides a kind of scheme being controlled dust quality by the belted mode of gear, the feed bin of the program uses stirring sheet to control the dust quantity dropping on ash conveying device, this scheme is because the dust accumulation density in feed bin is different, cause being accurately controlled the dust quality dropped on conveyer device, when life-time service, the guarantee of stable equilibrium can not send out dirt quality, experimental error is too big, it is difficult to reflect accurately and reliably the efficiency of cleaner unit.
The Chinese invention patent that application number is " dust aerosol generating device " by name of 201010101408.x provides a kind of technical scheme utilizing negative pressure technique attraction dust to send, the program drops to the dust quantity on belt conveyor by using the dust Control in the pectination brush stirring bunker in feed bin, the effect of pectination brush is similar to the stirring sheet of above-mentioned patent, equally exist because the change of feed bin situation causes that the situation that is difficult to accurately control bin blanking, life-time service can cause experiment to there is bigger error.
Above-mentioned several dust aerosol powder producer can only qualitative estimation powder amount number, and can not accurate quantification control dust send out dirt quality, can not pre-set send out a dirt quality, obtain requirement of experiment need send out dirt effect.It is bigger that above-mentioned several powder producer sends out dirt error, it is difficult to controls to send out the accuracy of dirt quality, and the reliability for dust collector efficiency detection is low.
