Abstract
The utility model discloses a novel venturi tube which comprises a venturi tube. The novel venturi tube is characterized in that a plurality of diversion plates with certain inclination angles and clearances are formed on the peripheral side edges of the venturi tube. The plurality of diversion plates are formed on the peripheral side edges of the venturi tube provided by the utility model, so that when a cloth bag plays a role in filtering, clean flue gas can be discharged out upward from an opening at the lower part of the venturi tube and from the diversion plates at the periphery of the venturi tube, the flue gas circulation area is enlarged, air at a bag opening can be guided to be distributed uniformly, a cloth bag close to the venturi tube is utilized effectively, meanwhile, the resistance increase of a cloth bag dust remover is reduced maximally, and the filter bag is prevented from being damaged by over-high local resistance.
Description
Technical field
The utility model relates to a kind of Venturi tube for the pulse jet sack cleaner.
Background technology
The pulse jet sack cleaner is a kind of typical dry-type dedusting equipment.Venturi tube is the critical component of pulse jet sack cleaner, and vertical hanging is installed on bag cage of filter bag mouth place in the pulse jet sack cleaner upper box, overlaps with the spot welding of bag cage.Venturi tube mainly plays a part to carry out gas flow guiding for compressed air and flue gas in the pulse jet sack cleaner, with the air-flow correct guidance filter bag of injection pipe of deduster ejection, avoids air-flow inclination damage cloth bag sidewall and improves the impact depth of gas.In addition, it to also have an effect be to promote the air-flow of ejection fully to mix with the secondary gas flow of being induced by it to carry out energy exchange.But Venturi tube has two shortcomings.At first, hang the cloth bag of this section of Venturi tube, lost the filtration of cloth bag because flue gas can't circulate.The sack distribution of gas is bad like this, some part of sack cleaner system reaches 150 m/min or the higher air-flow rate of climb, and other parts then are the air dead bands or adverse current is arranged, and cause the clean usable floor area of pulse jet sack cleaner to reduce, filtration velocity improves, and filter bag damages too early; Secondly, because Venturi tube winding-up mouth reduces 50%-70% with respect to former marsupial cage open area, cause flue gas flow rate to increase, so sack cleaner resistance increase after the upper Venturi tube, the air-introduced machine power consumption increases, and causes the electricity charge to increase.Therefore, in the sack cleaner system, take some that air-flow is evenly distributed and the measure that reduces dust remover resistance is very important.
The purpose of this utility model is to provide a kind of Venturi tube that air-flow is evenly distributed and reduces dust remover resistance.
The technical solution adopted in the utility model is: a kind of Novel venturi, comprise Venturi tube, and it is characterized in that: side is offered a plurality of deflectors with certain inclination angle and gap around the described Venturi tube.
The interval vertical interval of described deflector is 4-30 cm, with the inclination angle of central axis be the 20-40 degree.
The utility model around side offer a plurality of deflectors, thereby when cloth bag carries out filtration, clean flue gas can not only up be discharged from the Venturi tube lower part outlet, can also discharge by the deflector that distributes around the Venturi tube, so just increased the circulation area of flue gas, guiding sack air evenly distributes, and the cloth bag of Venturi tube annex is utilized effectively, simultaneously, reduce to greatest extent the increase of sack cleaner resistance and prevent the excessive infringement that causes filter bag of local resistance.
Description of drawings
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the work schematic diagram of the utility model when the sack cleaner cloth bag compresses deashing;
Fig. 3 is the work schematic diagram of the utility model when the sack cleaner cloth bag carries out the filter bag filtration.
The specific embodiment
Below in conjunction with accompanying drawing and implementation example the utility model is further elaborated.
As can be seen from Figure 1, the utility model Novel venturi, side is offered a plurality of deflectors 4 with certain inclination angle and gap around Venturi tube 3, wherein the interval vertical interval of deflector is 4-30 cm, with the inclination angle of central axis be the 20-40 degree.
As can be seen from Figure 2, when the sack cleaner cloth bag compresses deashing, clean flue gas enters the deflector and outlet at bottom of side of Venturi tube 3 of sack cleaner entrance from the winding-up outlet of injection tube 1 below after, with certain velocity shock sack cleaner cloth bag 2, clean out the dust that adheres on the sack cleaner cloth bag; As can be seen from Figure 3, when sack cleaner cloth bag 2 carried out filter bag filtration work, gas with dust is bag filtration after filtration, and the deflector 4 of Purge gas through Venturi tube 3 and side thereof enters upper box and discharge.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
