Abstract
The utility model discloses a lengthened Venturi nozzle of a bag filter, which is composed of a nozzle body, a nozzle air inlet end and a nozzle air outlet end. The utility model is characterized in that a lengthened pipe is additionally arranged among the throat part of the nozzle body, an air inlet pipe and an air outlet pipe. The ratio of the length of the nozzle body and the diameter of the end surface of the air inlet end is 1.2-1.5: 1. Because the utility model is additionally provided with the lengthened pipe at the throat part of a common Venturi nozzle, i.e. the length of the nozzle body of the Venturi nozzle is lengthened, jet flows formed by the lengthened Venturi nozzle of a bag filter are stabler so that the speed of air flows is retained, therefore pressure transmitted to a bag bottom is larger so that the bag bottom can get enough ash cleaning pressure when ash is cleaned; the utility model also enlarges draining air flow so that the bag bottom has strong ash cleaning strength and good ash cleaning effect. The utility model has the advantages that the length of the nozzle body is lengthened so that the bag bottom gets enough ash cleaning pressure, therefore the utility model improves the ash cleaning effect of the bag bottom of a filter bag and achieves the comprehensive and high-efficiency ash cleaning goal.
Description
Technical field
The utility model relates to the blowing device of sack cleaner, especially relates to a kind of extended type Venturi nozzle that can further improve the winding-up effect.
Background technology
Venturi nozzle plays an important role in the sack cleaner injection system, during deashing, at the bottom of Venturi nozzle can be preferably be passed to pressure bag, thereby has guaranteed the ash-removal effect of whole piece filter bag.In addition, when compressed air sprays into Venturi nozzle, this Venturi nozzle plays a part a kind of jet pump, high-speed jet by Venturi nozzle has produced negative pressure in filter bag is suitable for reading, thereby the gas that has purified that can aspirate the 80% pulse of air amount that is equivalent to from filter bag top enters filter bag by Venturi nozzle and carries out deashing, reaches the purpose of removing the outer ash cake of filter bag fully.Because the nozzle body of plain edition Venturi nozzle is made up of the escape pipe of air inlet pipe that narrows and expansion, the length of nozzle body is 1: 1 with the ratio of the end face diameter of inlet end, therefore in actual application, the bottom deashing of finding the part filter bag is thorough inadequately, reason is because the nozzle body length of plain edition Venturi nozzle is too short, have only 1: 1 with the ratio of the end face diameter of inlet end, thereby the pressure at the bottom of being sent to bag is not enough, ash-removal effect is poor.
Summary of the invention
Thereby the purpose of this utility model be to provide a kind of at the bottom of obtaining enough deashing pressure and then improve the filter bag bag at the bottom of making bag by the extended jet nozzle body length ash-removal effect, reach comprehensively efficient deashing purpose sack cleaner extended type Venturi nozzle.
The purpose of this utility model is achieved in that the utility model is made up of nozzle body, nozzle inlet end and nozzle outlet side, and feature is to have additional extension pipe between throat, air inlet pipe and the escape pipe at nozzle body.
The length of nozzle body is 1.1-1.5 with the ratio of the end face diameter of inlet end: 1.
The tube wall of extension pipe is parallel with the central axis of nozzle body.
The utility model is owing to have additional extension pipe in plain edition Venturi nozzle throat, the length of nozzle body of Venturi nozzle has promptly extended, the jet that venturi is formed is more stable, kept air velocity, can be owing to short mouth causes jet dynamics deficiency, thereby make the pressure at the bottom of being passed to bag just bigger, also just can obtain enough deashing pressure during deashing at the bottom of the bag; And increased drainage tolerance, and bag end deashing dynamics strengthens, and ash-removal effect is just better.Therefore thereby the utlity model has ash-removal effect at the bottom of obtaining enough deashing pressure and then improve the filter bag bag at the bottom of making bag by the extended jet nozzle body length, reach comprehensively efficient deashing purpose advantage.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a winding-up effect schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
The utility model is made up of nozzle body 4, nozzle inlet end 6 and nozzle outlet side 1, has additional extension pipe 3 between throat, air inlet pipe 5 and the escape pipe 2 of nozzle body 4.
The length of nozzle body 4 is 1.1-1.5 with the ratio of the end face diameter of nozzle inlet end 6: 1
The tube wall of extension pipe 3 is with parallel with the central axis of nozzle body 4.
