Description
Technical field
The utility model relates to a kind of dust exhaust apparatus being arranged at chlor-alkali industry acetylene generator, calcium carbide awning and iron notch of calcium carbide furnace, especially a kind of semi-hermetic type dust suction fume trap cover.
Background technology
In chlor-alkali industry acetylene generator, calcium carbide awning and calcium carbide smelting process, the process of furnace of calcium carbide stokehold tapping hole airborne dust is comparatively complicated, produce a large amount of thermal current at short notice, not only with instantaneous high-temperature simultaneously with strong heat radiation, have certain injury to operating personnel's health before machine.Current domestic blast furnace casting technique generally arranges simple umbrella shape dust shield at tapping hole, but due to the diversity space characteristics of umbrella shape, do not reach airtight requirement, cause the airborne dust of tapping hole easy to be outside climing loose, be unfavorable for that deduster carries out continuous print dedusting work, simultaneously owing to adopting single suction port to carry out dust suction process, although suction is larger, but suction is uneven, cause the center pick-up performance of dust shield obvious, the edge pick-up performance of dust shield is poor, and ash-laden gas slime flux goes out outside cover, can pollute surrounding environment, and the health of plant operations personnel is damaged.
There is provided a kind of pick-up performance evenly, airborne dust not easily outside climing loose dust suction fume trap cover be those skilled in the art's technical issues that need to address.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of pick-up performance evenly, prevent the outside climing loose semi-hermetic type dust suction fume trap cover of airborne dust.
In order to solve the problem, the utility model provides a kind of semi-hermetic type dust suction fume trap cover, this semi-hermetic type dust suction fume trap cover is made up of multiple dust suction cabin, each dust suction cabin is dustpan-shaped, and opening down side's homonymy is arranged, each dust suction cabin roof is provided with equally distributed, at least two air suction openings, and the suction in each dust suction cabin is more evenly distributed, and reduces airborne dust outside climing loose.
Further, described each air suction opening is provided with the one-level suction channel that sealing is connected, described airborne dust enters one-level suction channel by the multiple air suction openings be distributed in same dust suction cabin and carries out dust suction process, the one-level suction channel of air suction opening belonging to described same dust suction cabin crosses to arrange and forms secondary suction channel, be convenient to centrally dispose the airborne dust in same dust suction cabin, reduce energy consumption.
Further, the secondary suction channel in described different dust suction cabin crosses and arranges formation three level suction passage, is convenient to centrally dispose the airborne dust in same dust suction fume trap cover, reduces energy consumption.
Further, described dust suction cabin opening part is distributed with the arrangement of multi-disc parallel spaced-apart and the flow deflector that can turn to, or the flow deflector of louvre type, is convenient to carry out drainage to airborne dust.
Further, described flow deflector transverse direction, longitudinal or oblique setting, the flow deflector setting direction in adjacent dust suction cabin is different, and pick-up performance is better.
Further, be provided with shifting board between each dust suction cabin, make each dust suction cabin form hemi-closure space, avoiding interacts between each dust suction cabin causes pick-up performance to decline.
Further, described each dust suction cabin is provided with three air suction openings, and each air suction opening is distributed in each summit place of same equilateral triangle, and each dust suction cabin inner suction is evenly distributed, and pick-up performance is better.
The technique effect of utility model: (1) semi-hermetic type dust suction of the present utility model fume trap cover, relative to prior art, the multiple air suction openings being distributed in each cabin make the suction in each dust suction cabin be more evenly distributed, and reduce airborne dust outside climing loose, pick-up performance is better; (2) be provided with shifting board between each dust suction cabin, make each dust suction cabin form hemi-closure space, avoiding interacts between each dust suction cabin causes pick-up performance to decline; (3) suction channel of multistage through setting, can centrally dispose the airborne dust in same dust suction cabin, same dust suction fume trap cover, reduces energy consumption.
Accompanying drawing explanation
Below in conjunction with Figure of description, the utility model is described in further detail:
Fig. 1 is the perspective view of the utility model semi-hermetic type dust suction fume trap cover;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the right view of Fig. 1.
In figure: dust suction cabin 1, dust suction cabin roof 2, air suction opening 3, one-level suction channel 4, secondary suction channel 5, three level suction passage 6, shifting board 7, flow deflector 8.
Detailed description of the invention
Embodiment 1 as shown in Figures 1 to 3, the semi-hermetic type dust suction fume trap cover of the present embodiment, comprising 3 dust suction cabin other embodiments of 1(can be 4,5 etc.), each dust suction cabin 1 is in dustpan-shaped, and opening down side's homonymy is arranged, be provided with shifting board 7 between each dust suction cabin 1, make each dust suction cabin 1 form hemi-closure space, avoiding interacts between each dust suction cabin causes pick-up performance to decline.
It can be 4,5 etc. that dust suction cabin roof 2 is respectively provided with 3 other embodiments of air suction opening 3(), each air suction opening 3 is distributed in each summit place of same equilateral triangle, and each dust suction cabin 1 inner suction is evenly distributed, and pick-up performance is better; Each air suction opening 3 is provided with the one-level suction channel 4 that sealing is connected, and the one-level suction channel 4 of air suction opening belonging to same dust suction cabin crosses to arrange and forms secondary suction channel 5, is convenient to centrally dispose the airborne dust in same dust suction cabin; Secondary suction channel 5 crosses and arranges formation three level suction passage 6, is convenient to centrally dispose the airborne dust in same dust suction fume trap cover, reduces energy consumption.
