Description
Affiliated technical field
The present invention relates to a kind of pulse spraying equipment, the proving installation and the method for particularly a kind of pulse jet jet angle and jet angle of deviation.
Background technology
At present, China's pulse bag type dust collector has become the main flow of industrial dedusting aspect development, it mainly be with pressurized air to the filter bag pulse dust cleaning, the quality of pulse dust cleaning Component Design just seems particularly important so.Pulse gas winding-up pipe mainly is that the factor that influences the jet angle mainly contains two according to the nozzle jet angle decision on the winding-up pipe to the distance of card face, and one is the size of pulse air pressure, and one is the size of the nozzle on the winding-up pipe.In engineering design, generally rule of thumb come to determine the distance of winding-up pipe, can not guarantee that but jet-stream wind covers the length of whole piece filter bag, cause the deashing inequality to the card face, even owing to the air-flow deflection is damaged filter bag.
Summary of the invention
Technical matters to be solved by this invention is: proving installation and method that a kind of pulse jet jet angle and jet angle of deviation are provided; can accurately calculate jet angle and jet angle of deviation; be applied in the engineering design then; make the winding-up air-flow can cover the whole piece filter bag length; strengthen ash-removal effect; the protection filter bag prolongs life of bag filter.
The technical solution adopted for the present invention to solve the technical problems is:
The proving installation of a kind of pulse jet jet angle and jet angle of deviation comprises pulse valve, gas bag, is provided with winding-up pipe, source of the gas processor, air compressor, the pulse control instrument of some nozzles, and described pulse valve is connected with gas bag, pulse control instrument respectively; One side of described gas bag is connected with source of the gas processor, air compressor successively by pipeline; Described winding-up pipe passes gas bag and is connected with pulse valve, also has additional filler on described winding-up pipe, and the below of described winding-up pipe is provided with the image web plate.
The method of testing of a kind of pulse jet jet angle and jet angle of deviation comprises the steps:
(1) the colored shadow liquid of filling in filler at first by pulse valve pulse venting, is ejected into colored shadow liquid on the image web plate by nozzle;
When (2) the colored shadow liquid on being ejected into the image web plate forms the jet image, measure image diameter D and image offset amount t;
(3) then according to the diameter d of nozzle, nozzle is to the distance h of image web plate, and the image diameter D and the image offset amount t that measure gained, passes through formula
Calculate the jet angle, pass through formula
Calculate the jet angle of deviation.
The invention has the beneficial effects as follows: at the winding-up Guan Shangshe of existing pulse spraying equipment one filler, and below the winding-up pipe, establish an image web plate, can in filler, annotate and be ejected into the image web plate from nozzle behind the colored shadow liquid and form the jet image, measure image diameter D and image offset amount t then, again according to the diameter d of nozzle and nozzle to the distance h of image web plate, can accurately calculate jet angle and jet angle of deviation by formula.In engineering design,, determine the distance of winding-up pipe from card in conjunction with the filter bag bore according to gas bag pressure, pulse valve resistance, factors such as winding-up pipe size, injection hole size and quantity; guarantee that the winding-up air-flow covers the whole piece filter bag length; strengthen ash-removal effect, the protection filter bag prolongs life of bag filter.
