Abstract
The utility model discloses a conical airflow inner cover for a flue gas collecting cover, which comprises a cylindrical inner cover arranged in an outer cover through channel steel, wherein the inner wall of the inner cover is coaxially provided with a conical pipe with wide inside and narrow outside through a steel plate; a plurality of through holes for allowing peripheral flue gas to enter the inner cover are uniformly formed in the outer wall of the inner cover above the conical pipe; the bottom ends of the outer cover, the inner cover and the taper pipe are on the same horizontal plane. The utility model discloses a toper air current inner cover, the regional flue gas in a large number entrapment center forms toper air current and distributes for the velocity of flow of flue gas has reduced the amount of wind, has finally reduced the cost of flue gas entrapment cover, can also promote the entrapment effect of flue gas simultaneously.
Description
Technical Field
The utility model relates to a technical field, especially a toper air current inner cover for flue gas entrapment cover are handled to flue gas.
Background
The traditional flue gas collecting cover needs to cover the whole airflow area for effectively collecting flue gas, so that the suction port of the collecting cover is large, and simultaneously, the requirement of the flow velocity of the suction port is met by larger air volume, so that the satisfactory dust removal effect is achieved.
However, in actual production, after the flue gas rises, the flue gas amount at the center of the flue gas flow is large, although the flue gas diffuses around, the general flue gas amount is small, the flow rate of the flue gas is relatively small, the flue gas flow rate of the large suction port trapping cover cannot be met, and the dust removal effect is not obvious.
Disclosure of Invention
The utility model aims to solve the technical problem that a toper air current inner cover for flue gas entrapment cover is provided, reduces entrapment cover suction inlet area, and the increase flue gas velocity of flow improves dust removal effect.
In order to solve the technical problem, the utility model adopts the following technical proposal.
A conical airflow inner cover for a flue gas collecting cover comprises a cylindrical inner cover arranged in an outer cover through channel steel, wherein a conical pipe with a wide inner part and a narrow outer part is coaxially arranged on the inner wall of the inner cover through a steel plate; a plurality of through holes for allowing peripheral flue gas to enter the inner cover are uniformly formed in the outer wall of the inner cover above the conical pipe; the bottom ends of the outer cover, the inner cover and the taper pipe are on the same horizontal plane.
The channel steel is of a square structure, and the screen plate convenient for flue gas to enter the outer cover is arranged between the channel steel and the inner cover.
The conical airflow inner cover for the flue gas collecting cover is characterized in that the channel steel is steel structure channel steel.
Due to the adoption of the technical scheme, the utility model has the following technical progress.
The utility model discloses a toper air current inner cover, the regional flue gas in a large number entrapment center forms toper air current and distributes for the velocity of flow of flue gas has reduced the amount of wind, has finally reduced the cost of flue gas entrapment cover, can also promote the entrapment effect of flue gas simultaneously.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a side view of the present invention;
wherein: 1. the steel plate screen comprises an outer cover, 2. channel steel, 3. an inner cover, 4. a steel plate, 5. a taper pipe and 6. a screen plate.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
A conical airflow inner cover for a flue gas trapping cover is structurally shown in figures 1-2 and comprises an outer cover 1 and an inner cover 3, wherein the inner cover 3 is arranged in the outer cover 1 through channel steel 2 and used for trapping flue gas.
Be provided with taper pipe 5 through steel sheet 4 on the inner wall of inner cover 3, taper pipe 5 is the structure of interior wide outer narrow, and taper pipe 5 and 3 coaxial settings of inner cover, the bottom of dustcoat 1, inner cover 3 and taper pipe 5 are at same horizontal plane. The conical inner cover is formed by arranging the conical pipe in the inner cover 3, smoke in the central area is greatly collected, conical airflow distribution is formed, and the flow speed of the smoke can be accelerated.
The outer wall of the inner cover 3 above the conical pipe 5 is evenly provided with a layer of through holes for enabling the smoke around to enter the inner cover, part of the smoke enters the inner cover from the outside through the through holes, and part of the smoke enters the inner cover from the conical pipe, and after a large amount of smoke enters the conical airflow inner cover rapidly, conical airflow distribution is formed.
The utility model discloses well flue gas is when passing through the inner cover, and the flue gas volumn at center is great, accelerates the velocity of flow through toper air current inner cover, and outside flue gas volumn is less, carries out the entrapment through the dustcoat, can make the flue gas be toper air current distribution like this for the flue gas of flue gas collecting cover below forms obvious toper interface, and the central region flue gas velocity of flow accelerates, and the flue gas stream of whole toper part makes dust removal effect very obvious.
