Abstract
The utility model relates to a deashing device for a pulse-jet bag type dust remover, which belongs to the technical field of the dust removal equipment. The device comprises a filter bag with a bag mouth fixed on a tube sheet, wherein, a venturi tube is arranged in the bag mouth of the filter bag, and the venturi tube is composed of a converging tube, a throat opening and a diverging tube. The deashing device is characterized in that the venturi tube is supported on the tube sheet through a bracket on which a spacing hole is produced, and a side hole is arranged on the side wall of the diverging tube. When the filter bag is in a filtering state, the dust is blocked outside the filter bag, and the clean air entering into the filter bag mostly enters into the outside of the venturi tube through the side hole on the side wall of the diverging tube, then enters into the air exhaust pipe of the pulse-jet bag type dust remover through the spacing hole of the bracket, and then is discharged outside the pulse-jet bag type dust remover. Compared with the prior art, the deashing device has the advantages of small filtration resistance, enhanced filtration capacity and energy resource conservation.
Description
Technical field
The utility model relates to a kind of industrial dedusting pulse bag type dust collector, and especially a kind of architecture advances of pulse blowing bag type dust precipitator deashing device belongs to the cleaner technical field.
Background technology
Pulse blowing bag type dust precipitator because of save the energy, the equipment operation management expense is low, efficiency of dust collection is high, save plurality of advantages such as capital expenditure, volume and floor space are little, development is very fast abroad, the trend that replaces chamber-dividing counter-blowing sack cleaner and electric cleaner is arranged, and application at home is also more and more.
For range that increases pulse jetting deashing and the filter bag that keeps the filter pocket mouths position are difficult for being washed out by the high-speed pulse air-flow, Venturi tube is installed at the filter pocket mouths position usually.The weak point of prior art Venturi tube is that the gas-flow resistance loss at Venturi tube aditus laryngis position is too big: when filter bag is in the filtration state, this filter bag gas inside will be all by the aditus laryngis position of Venturi tube, and the result causes drag losses big (referring to Fig. 1).
The utility model content
The purpose of this utility model is: the weak point at above prior art exists by the architecture advances to Venturi tube, proposes a kind of pulse blowing bag type dust precipitator deashing device that can reduce gas-flow resistance loss, energy savings.
In order to reach above purpose, pulse blowing bag type dust precipitator deashing device of the present utility model comprises that sack is fixed on the filter bag on the card, the sack of described filter bag is equipped with Venturi tube, described Venturi tube is made of reducing pipe, aditus laryngis and increaser, its improvements are: the bracket support of described venturi by being shaped on spacer holes is on card, and the sidewall of described increaser has sidewise hole.
When filter bag is in the filtration state, dust is blocked on the filter bag outside, the clean gas that enters the filter bag the inside can most ofly enter the Venturi tube outside by the sidewise hole on the Venturi tube increaser sidewall, enter the blast pipe of pulse bag type dust collector again through the spacer holes of carriage, it is external to be discharged to pulse bag type dust collector.Therefore, compared with prior art, filtration resistance is little, can strengthen filter capacity, energy savings.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the prior art constructions schematic diagram.
Fig. 2 is the structural representation of an embodiment of the utility model.
Fig. 3 is the cutaway view of Fig. 2.
Among the figure: the 1-filter bag; The 2-card; The 3-carriage; The 4-Venturi tube; The 5-increaser; The 6-sidewise hole; The 7-aditus laryngis; The 8-reducing pipe; 9. carriage spacer holes.
The specific embodiment
Embodiment one
The pulse blowing bag type dust precipitator deashing device of present embodiment as shown in Figures 2 and 3, the sack of filter bag 1 is fixed on the card 2 in the deduster.Venturi tube 4 is made of reducing pipe 8, aditus laryngis 7 and increaser 5, is supported on the card 2 by the carriage 3 that is shaped on spacer holes 9, and the sidewall of increaser 5 has one group of sidewise hole 6.
Venturi tube 4 and carriage 3 can be connected as a single entity, and also can be separable two parts.Some sidewise holes 6 on the Venturi tube increaser 5 and some spacer holes 9 of carriage 3 design for the drag losses of reduction Venturi tube aditus laryngis 7 positions by gas.When filter bag 1 is in running order, dust in the gas is blocked on the outside of filter bag 1, clean gas major part after the filtration enters into the outside of Venturi tube 4 by the sidewise hole on the Venturi tube increaser 56, and it is external that the discharge duct that enters pulse dust collector through the spacer holes 9 of venturi pipe carrier 3 is discharged to pulse bag type dust collector.Like this, compared with prior art, it is about 50 percent to reduce the drag losses of Venturi tube aditus laryngis 7 parts, and effect is very remarkable.
In addition to the implementation, the utility model can also have other embodiments.For example, the quantity of sidewise hole and spacer holes can change as required, and its shape can be round, oval, square or rectangle, slit etc.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
