Detailed Description
In order to further explain the technical scheme of the invention, the invention is explained in detail by specific examples.
A wind control cylinder for a combustion furnace core, as shown in fig. 1 and 2, comprises a wind control cylinder 3. The air control cylinder 3 is suitable for the furnace core of the compression type combustion furnace and can be arranged in the main shell of the furnace core.
The wind control cylinder 3 takes the orientation shown in fig. 1 as a reference orientation and is cylindrical and comprises an open section 31, a middle section 32 and a sealing section 33 which are sequentially connected from bottom to top. The ratio of the outer diameter to the height of the wind control cylinder 3 is 0.5-2.6, preferably 1. In the processing of a common specification furnace core, the outer diameter of the wind control cylinder 3 is 4 cm-8 cm, the height of the wind control cylinder 3 is 3 cm-8 cm, preferably, the outer diameter of the wind control cylinder 3 is 6cm, and the height is 6cm. The open section 31 corresponds to the position of the combustion bowl of the main housing of the burner hearth. The side wall of the middle section 32 is provided with a plurality of second air eyes 34 arranged along the circumferential direction of the air control cylinder 3, the second air eyes 34 penetrate from the outer side wall to the inner side wall of the middle section 32, and the second air eyes 34 are obliquely arranged along the anticlockwise direction from outside to inside. The second wind holes 34 are divided into two rows along the axial direction of the wind control cylinder 3, including a first row and a second row which are arranged in parallel up and down, and the first row is located above the second row. The second wind holes 34 located in the same row are equally spaced in the circumferential direction of the wind control cylinder 3. And the number of the second wind holes 34 in the first row and the second row is equal and is 6-20, preferably 12. The first row and the second eyes 34 of second row are crisscross to be set up, be "W" shape after connecting gradually from top to bottom in two rows of second eyes 34, specifically, if be located the second eye C of first row, and be located the triangle-shaped after connecting with F of second eye D of second row, like this, the crisscross setting of second eye 34 makes the wind that blows to the combustion bowl more even stable, during the use, the wind of second eye 34 blows to combustion bowl combustion-supporting from inside to outside, when the wind blowing force that receives in the combustion bowl is more balanced, the burning is more even, noise when can reducing the burning, and guarantee the fuel combustion in the main casing more abundant high-efficient. The sealing section 33 is provided with a plurality of first air holes 35 which are arranged at equal intervals along the circumferential direction of the air control cylinder 3, the first air holes 35 penetrate from the outer side wall to the inner side wall of the sealing section 33, the first air holes 35 are obliquely arranged from outside to inside along the clockwise direction, and the plurality of first air holes 35 are arranged in a regular row and are positioned above the two rows of second air holes 34.

The diameters of the base plates are equal in the direction from the seal segment 33 to the open segment 31, or, as shown in fig. 3, the diameters of the base plates are reduced in the direction from the seal segment 33 to the open segment 31, i.e., the thickness direction of the base plates. It should be noted that, as shown in fig. 4, the diameter of the bottom plate is equal to the outer diameter of the side wall of the sealing section, i.e. the bottom plate is flush with the side wall of the sealing section. The invention is suitable for the oil-gas dual-purpose combustion furnace. The number of the air holes, namely the distribution density and the like can be adaptively adjusted according to the specification and the size of the furnace core and other factors. The distribution density of the first wind eyes 35 or the second wind eyes 34 of each row may be the same or different.
After the technical scheme is adopted, the side wall of the air control cylinder 3 is provided with the first air hole 35 and the second air hole 34, and the normal combustion use of the furnace core is ensured through wind power combustion supporting. The air hole of the traditional combustion furnace core is mainly arranged in the main shell fixedly arranged, the main arrangement position of the air hole of the traditional combustion furnace core is changed, further, the air control cylinder 3 can be directly arranged in the main shell of the combustion furnace core, the taking is convenient, the cleaning is easy even if the air hole of the air control cylinder 3 is blocked, the air inlet is smooth during the use, and the combustion is more efficient and low in noise.
