Abstract
The utility model relates to an important part applied to a combustion equipment in a circulating fluidized bed furnace, in particular to an anti-wear funnel cap. The anti-wear funnel cap comprises a ventilating plate and an oblique ventilating hole arranged evenly on the ventilating plate; an inclining direction of the ventilating hole is identical; an inclination of the ventilating hole is the same. The inclination of the ventilating hole is 5 degrees to 45 degrees. Because of a plurality of oblique ventilating holes machined evenly on the ventilating plate, the identical inclining direction of the ventilating holes and the same inclination of 5 degrees to 45 degrees, a blown-out air current is parallel with a rear of the ventilating hole so as not to blow directly on the rear of the front adjacent ventilating hole, which completely solves the problem that the funnel is worn because of being blown by the air current, thereby lengthening the service life of the funnel cap.
Description
Technical field
The utility model relates to a kind of vitals that is applied on the CFBB internal combustion equipment, relates in particular to a kind of anti-wear cowl.
Background technology
In CFBB, blast cap is important composition parts of combustion apparatus, in the boiler that the FICIRC circulating fluidized bed technique of China's introduction nineties in 20th century U.S. CPC International Inc. is produced, blast cap is to be formed by ventilative board, air duct, airduct bond pads, the ventilative board upper punch be pressed with some have identical shaped, equidirectional
The shape air-permeating hole, air communication is crossed air compartment and is come out from air-permeating hole from bottom to top, its direction is basically parallel to air distribution plate, cause material laterally disturbance at a high speed at the boiler furnace emulsion zone, be beneficial to abundant burning and fuel and contact, but this parallel gas flow is easy to blow on the back of the adjacent air-permeating hole in air-flow the place ahead with the abundant mixing of sulphur removal with lime stone, if long-time running, fine particle in the air-flow is easy to damage ventilative board, causes blast cap to leak out, thereby influences the normal operation of boiler.
The utility model content
The purpose of this utility model is to provide a kind of anti-wear cowl, directly blows on the back of adjacent air-permeating hole forwardly to avoid air-flow.
In order to achieve the above object, anti-wear cowl of the present utility model is to adopt a kind of anti-wear cowl, comprises ventilative board, evenly is provided with the inclination air-permeating hole on the ventilative board, described air-permeating hole incline direction unanimity, and the inclination angle is identical.
Described air-permeating hole inclination angle is 5 °-45 °.
Owing on ventilative board, evenly be processed with the inclination air-permeating hole of some, air-permeating hole incline direction unanimity, the inclination angle is identical, it is 5 °-45 °, the air-flow that is blown out is parallel with the back of air-permeating hole like this, just can directly not blow on the back of adjacent forwardly air-permeating hole, thoroughly solve airflow scouring and made the blast cap wear problem, thereby prolonged the service life of blast cap.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2, anti-wear cowl shown in Figure 3, evenly be processed with inclination air-permeating hole 2 on the ventilative board 1, air-permeating hole incline direction unanimity, the inclination angle is identical, be 15 ° (better action all can be played at 5 °-45 ° in the inclination angle), circular ventilative board 1 welds mutually with conical air duct 3, and air duct 3 welds together with airduct 4.In addition, air duct 3 can also be a polygonal pyramid shape, and ventilative board 1 can also be the equilateral polygon of corresponding sides number, repeats no more herein.
Claims (2)
1. an anti-wear cowl comprises ventilative board, it is characterized in that: evenly be provided with the inclination air-permeating hole on the ventilative board, and described air-permeating hole incline direction unanimity, the inclination angle is identical.
2. anti-wear cowl according to claim 1 is characterized in that: described air-permeating hole inclination angle is 5 °-45 °.
