Furthermore, the bypass has the characteristics of simple structure, convenience in installation and maintenance, low manufacturing cost and the like.
Description
Technical field
The utility model belongs to the dedusting technology field, particularly relates to a kind of high-temperature-resistant cloth bag dust collector with internal bypass, is applicable to limekiln industry kiln tail dedusting.
Background technology
Along with the increasingly stringent of national environmental protection policy and the entry criteria requirement of limekiln industry, newly-built limekiln must be equipped with perfect dust removal installation.Tradition is with the high-temperature-resistant cloth bag dust collector of internal bypass successful Application in the limekiln flue gas is processed, tradition is arranged on the dividing plate of the inner blast pipe of deduster and discharge pipe with the by-passing valve of the high-temperature-resistant cloth bag dust collector of internal bypass, its advantage be simple in structure, cost is low, shortcoming is that the dividing plate that by-passing valve is set is swash plate, require high to valve seal, and installation and maintenance are inconvenient, a kind of novel shortcoming that solves traditional internal bypass with the high-temperature-resistant cloth bag dust collector of internal bypass of market in urgent need.
Summary of the invention
The purpose of this utility model is to provide a kind of high-temperature-resistant cloth bag dust collector with internal bypass, has overcome traditional internal bypass limekiln tail deduster accuracy of manufacture and has required the shortcoming high, that installation and maintenance are inconvenient.By the deduster structural design, bypass is arranged on the deduster outside, install and overhaul convenient, and can guarantee flue gas by-passing state the time, cloth bag and flue gas completely cut off fully, clean in clean casing.This bypass has simple in structurely, easy for installation in addition, is convenient to maintenance, and the characteristics such as cost is low make product function abundanter more perfect, make the scope of application of product broader.
The utility model comprises air intake house steward 1, air-out house steward 2, the first dividing plate 3, pneumatic by-passing valve 4, electronic stop valve 5; Be provided with dividing plate 3 between air intake house steward 1 and air-out house steward 2, be provided with pneumatic by-passing valve 4 on the first dividing plate 3, the valve gap of pneumatic by-passing valve 4 coordinates with by-pass port and is used for opening or closing by-pass port; Enter air intake house steward 1 on the arm of ash bucket 6 and establish electronic stop valve 5, on the second partition 7 between air-out house steward 2 and clean casing, pneumatic power lifting valve 8 is set.
Air intake vent place at deduster arranges pneumatic by-passing valve 4, and when making fume high-temperature abnormal, the very first time enters into air-out house steward 2 by pneumatic by-passing valve 4 from air intake house steward 1, avoids high-temperature flue gas to pass in the air intake house steward.The utility model internal bypass is included in the deduster porch interconnective air intake house steward 1 and air-out house steward 2 is set, establish first between air intake house steward 1 and air-out house steward 2 dividing plate 3 is arranged, be provided with pneumatic by-passing valve 4 on the first dividing plate 3, the valve gap of by-passing valve coordinates with by-pass port and is used for opening or closing by-pass port; Enter air intake house steward 1 on the arm of ash bucket 6 and establish electronic stop valve 5, on the second partition 7 between air-out house steward 2 and clean casing, pneumatic power lifting valve 8 is set.The utility model internal bypass is compared with existing internal bypass, and its installs and overhaul convenient, and can guarantee flue gas by-passing state the time, cloth bag and flue gas completely cut off fully, and only clean in casing.This bypass has simple in structurely, easy for installation in addition, is convenient to maintenance, the characteristics such as cost is low.
The beneficial effects of the utility model are: adopt novel high-temperature-resistant cloth bag dust collector with internal bypass, effectively having solved traditional high-temperature-resistant cloth bag dust collector valve seal with internal bypass requires high, and the shortcoming of installation and maintenance inconvenience has improved the applicability with the high-temperature-resistant cloth bag dust collector of internal bypass.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the schematic diagram of a kind of operating mode of the utility model.
Fig. 2 is the schematic diagram of the another kind of operating mode of the utility model.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is that the A-A of Fig. 3 is to view.
In figure: air intake house steward 1, air-out house steward 2, the first dividing plate 3, pneumatic by-passing valve 4, electronic stop valve 5, ash bucket 6, second partition 7, pneumatic power lifting valve 8.
The specific embodiment
The utility model comprises air intake house steward 1, air-out house steward 2, the first dividing plate 3, pneumatic by-passing valve 4, electronic stop valve 5; Be provided with the first dividing plate 3 between air intake house steward 1 and air-out house steward 2, be provided with pneumatic by-passing valve 4 on the first dividing plate 3, the valve gap of pneumatic by-passing valve 4 coordinates with by-pass port and is used for opening or closing by-pass port; Enter air intake house steward 1 on the arm of ash bucket 6 and establish electronic stop valve 5, on the second partition 7 between air-out house steward 2 and clean casing, pneumatic power lifting valve 8 is set.
At first to carry out on-line monitoring to the deduster entrance flue gas temperature, then carry out bypass changeover by the high-temperature-resistant cloth bag dust collector with internal bypass.
Below in conjunction with accompanying drawing and example, the utility model is further described, but the utility model is not limited to this example.
The utility model is responsible for collecting with the high-temperature-resistant cloth bag dust collector of internal bypass the flue dust that the limekiln tail distributes.When the limekiln is normally moved, flue-gas temperature is between 150 ℃-220 ℃, and the high-temperature-resistant cloth bag dust collector of internal bypass normally moves, and this moment, pneumatic by-passing valve 4 cut out, electronic stop valve 5 is opened, pneumatic power lifting valve 8 is opened, and flue gas enters from air intake house steward 1, enters in ash bucket 6 by electronic stop valve 5, enter clean casing after filtering through high temperature resistant filter bag, by being arranged on the pneumatic power lifting valve 8 on second partition 7 between clean casing and air-out house steward, flue gas enters air-out house steward 2, finally discharges deduster.when the limekiln accident is moved, flue-gas temperature will reach 350 ℃ of left and right, cloth bag can not bear high temperature like this, need to open bypass line with the high-temperature-resistant cloth bag dust collector of internal bypass, flue gas directly passes deduster and without cloth bag from bypass, this moment, pneumatic by-passing valve 4 was opened, electronic stop valve 5 cuts out, pneumatic power lifting valve 8 is closed, the high-temperature-resistant cloth bag dust collector by-pass operation of internal bypass, flue gas enters from air intake house steward 1, directly enter in air-out house steward 2 by pneumatic by-passing valve 4, electronic stop valve 5 and pneumatic power lifting valve 8 are closed, guarantee that flue gas and cloth bag are fully isolated, and clean in clean casing.
