Abstract
The invention relates to a spray head for a plenum pulse cloth bag collector, which is formed by hammer forging of a steel pipe, and is characterized in that an air inlet end of the spray head is in the shape of a circular cross section, an air outlet end is in the shape of a rectangular cross section, and the center of the circular cross section of the air inlet end can be aligned or not aligned with the center of the rectangular cross section of the air outlet end. The spray head has the advantages of simple structure, easy manufacture, uniform dust cleaning and capability of prolonging the service life of a filter bag.
Description
Technical field
The invention belongs to the industrial dedusting technical field, particularly a kind of shower nozzle that is used for plenum pulse cloth bag collector.
Background technology
Industrial gas tank pulse packet dust-precipitator is a kind of efficient dust collection device, is widely used in the treating flour dust of industrial circle.Present its compressed air spraying is a circular cross-section with the shower nozzle employing, when winding-up, the conical flow of being induced by circular cross section and the square cross-section of air-purifying chamber do not match, cause that the cleaning air-flow is in the air-purifying chamber maldistribution, have two problems: 1) the part filter bag ash removal is ineffective, can not effectively bring into play its filter capacity.2) part filter bag ash removal dynamics is excessive, the filter bag premature breakage.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of simple in structure, be easy to make and can guarantee that deashing is used for the shower nozzle of plenum pulse cloth bag collector uniformly.
The present invention for the technical scheme that solves the technical problem that exists in the known technology and take is: a kind of shower nozzle that is used for plenum pulse cloth bag collector, and forge by the steel pipe hammer and to form, be characterized in that the shower nozzle inlet end is a circular cross section, the outlet side is the rectangle section.
The present invention can also adopt following technical measures to realize:
Above-mentioned a kind of shower nozzle that is used for plenum pulse cloth bag collector is characterized in the center of described circular cross section and the center of rectangle section.
Above-mentioned a kind of shower nozzle that is used for plenum pulse cloth bag collector is characterized in that the center of described circular cross section and the center of rectangle section misalign.
Advantage and good effect that the present invention has are: because the rectangle section structure is adopted in the shower nozzle outlet side, when winding-up takes place, the square air-flow of compressed air by the ejection of shower nozzle rectangle section outlet side can be uniformly distributed in the air-purifying chamber, guarantee the deashing dynamics unanimity of filter bag in the same casing, avoid filter bag to cause the loss of filter area and the too early damage of part filter bag because of deashing dynamics inequality.The center of the center of shower nozzle inlet end circular cross section and outlet side rectangle section can centering also can misalign, and the steel pipe hammer can be forged into the shower nozzle of different structure type.Shower nozzle cooperates installation with air-purifying chamber, the cross dimensions employing difformity specification shower nozzle according to different installation sites and air-purifying chamber makes deashing even, reaches better ash-removal effect.The present invention also has advantage simple in structure, that be easy to make in addition.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
A kind of shower nozzle that is used for plenum pulse cloth bag collector, be to be L with a segment length, diameter is that the end of steel pipe 1 circular cross section of Φ (consistent with the pulse valve specification) is as inlet end 2, with the other end heating back hammer section of steel pipe 1 is highly to be A, width is that the outlet side 3 of the rectangle section of B forms, when being installed on plenum pulse cloth bag collector pure qi (oxygen) case inside, the inlet end of its circular cross section and the blast pipe of pulse valve welding (also can adopt be threaded or flange is connected), air-purifying chamber is inserted in the outlet side 3 of rectangle section, the duration limit is installed uses orifice plate parallel with the installation filter bag.As Fig. 1, Fig. 2, and shown in Figure 3,, can hammer into shape to forge and reach symmetrical shower nozzle pattern up and down the center of circular cross section and the center of rectangle section; As Fig. 4, Fig. 5, Figure 6 and Figure 7, the center of the center of circular cross section and rectangle section also can misalign, and hammer is forged up and down or the asymmetric shower nozzle pattern in the left and right sides.Shower nozzle can cooperate installation with air-purifying chamber, according to the cross dimensions employing difformity specification shower nozzle of different installation sites and air-purifying chamber.The shower nozzle of which kind of pattern no matter, its outlet side is the rectangle section, when winding-up takes place, the square air-flow of compressed air by the ejection of shower nozzle rectangle section outlet side can be uniformly distributed in the air-purifying chamber, guarantee the deashing dynamics unanimity of filter bag in the same casing, avoid filter bag to cause the loss of filter area and the too early damage of part filter bag because of deashing dynamics inequality.
