Abstract
The utility model discloses a device for detecting the inclination angle and the declination angle of a pulse jet. The device comprises a pulse valve, an air bag, an injection pipe with a plurality of nozzles, an air source processor, an air compressor and a pulse controller, wherein the pulse valve is respectively connected with the air bag and a pulse controller; one side of the air bag is sequentially connected with the air source processor and the air compressor through pipes; the injection pipe (at) is connected with the pulse valve through the air bag; an injection hole is also formed on the injection pipe; and an image halftone is arranged below the injection pipe. The device can accurately calculate the inclination angle and the declination angle of the jet, and the results can be used in engineering design so as to enable the injection jet to cover an entire filter bag in the length direction, thereby enhancing the cleaning effect, protecting the filter bag and prolonging the service life of the filter bag.
Description
Affiliated technical field
The utility model relates to a kind of pulse spraying equipment, the proving installation of 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.
The utility model content
Technical problem to be solved in the utility model is: the proving installation 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 scheme that its technical matters that solves the utility model adopts is: the proving installation of a kind of pulse jet jet angle and jet angle of deviation, comprise pulse valve, gas bag, be provided with winding-up pipe, source of the gas processor, air compressor, the pulse control instrument of some nozzles, 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 beneficial effects of the utility model are: 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 in conjunction with 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.

Fig. 2 is the structural representation at A place among Fig. 1.
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment
In conjunction with Fig. 1, shown in Figure 2, the proving installation of a kind of pulse jet jet angle and jet angle of deviation, comprise pulse spraying equipment, pulse valve 1 is installed on the gas bag 2, the centre is lined with sealing gasket 13, and tighten fixing with securing member 15, pulse valve 1 is connected with pulse control instrument 12 by lead 11, gas bag 2 passes on left pipeline 10 and is connected with air compressor 9 with source of the gas processor 8 successively, winding-up pipe 5 passes gas bag 2 backs and is connected with pulse valve 1, by 14 sealings of the O-ring seal in the pulse valve 1, is provided with nine nozzles 6 on winding-up pipe 5, the left side of nozzle 6 is provided with filler 4 on winding-up pipe 5, is provided with image web plate 7 under winding-up pipe 5.
In the practical application, at first by the colored shadow liquid 3 of filling in winding-up pipe 5 of the filler 4 on the winding-up pipe 5, open air compressor 9 and give feeding pressurized air in the gas bag 2, exit by 1 pulse of pulse control instrument 12 gating pulse valves again, colored shadow liquid 3 in the winding-up pipe 5 is ejected on the image web plate 7 by the nozzle 6 on the winding-up pipe 5, on image web plate 7, will form colored jet image, measure colored shadow liquid 3 then and spray the image diameter D that the back forms at image web plate 7 from nozzle 6, and the image offset amount t at the center of the center of nozzle diameter d and image diameter D, again in conjunction with the diameter d of nozzle 6, nozzle 6 passes through formula to the distance h of image web plate 7
Calculate the jet angle, pass through formula
Calculate the jet angle of deviation.
