Abstract
The utility model discloses a particle layered guide sleeve device for preventing boiler smoke tube abrasion, and belongs to the field of boiler equipment. In order to solve the problem that an end surface and a tube inner wall of the present boiler smoke tube are abraded easily. The device includes an ingress pipe arranged at an entrance section of the boiler smoke tube and connected with a particle layered guide device; gradually increased round holes or gradually thickened trapezoid holes are sequentially formed on the particle layered guide device; the particle layered guide device can have multi-stage distribution; and a protective cylinder is arranged outside the particle layered guide device. The particle layered guide sleeve device is mounted at the entrance section of the boiler smoke tube, and larger solid particles in smoke or waste heat gas can be layered and concentrated at the center area of the boiler smoke tube, so that the abrasion on the boiler smoke tube can be prevented or reduced, and the service life of the boiler smoke tube is prolonged.
Description
Technical field
The utility model relates to the boiler plant field, is specially a kind of Boiler smoke tube wear particle layering guide thimble device that prevents.
Background technology
The solid particle that contains in flue gas or the gas, the end face and the inside pipe wall of the Boiler smoke tube that can wear and tear influence the normal use of boiler.
Summary of the invention
End face and inside pipe wall defective easy to wear at existing Boiler smoke tube, the utility model aims to provide a kind of Boiler smoke tube wear particle layering guide thimble device that prevents, this device can prevent the Boiler smoke tube wearing and tearing, avoids the end face and the smoke pipe inner surface of abrasion of particles smoke pipe in flue gas or the gas.
For achieving the above object, the technical scheme that the utility model adopted is, the described Boiler smoke tube wear particle layering guide thimble device that prevents comprises the ingress pipe of the entrance that is arranged on Boiler smoke tube, its design feature is, end at described ingress pipe one end and flaring particle layering guider joins, and also is connected with a casing at this particle layering guider and described ingress pipe junction; Described particle layering guider is positioned at this casing.
Further, in order to improve the negotiability of flue gas in the smoke pipe, on the wall of described particle layering guider, have a plurality of holes.
Further, described hole is preferably circular hole, according to the diameter of circular hole being arranged sequentially on the particle layering guider from small to large, and the Circularhole diameter minimum of the heavy caliber end of particle layering guider wherein, the Circularhole diameter maximum of small-caliber end.
Certainly, described hole also can be trapezoidal hole, according to trapezoidal hole being arranged sequentially on the particle layering guider from small to large, and the trapezoidal hole minimum of the heavy caliber end of particle layering guider wherein, the trapezoidal hole maximum of small-caliber end.The trapezoidal base of described trapezoidal hole is towards the center of particle layering guider.
In technique scheme, be provided with a plurality of particle layering guiders in the described casing, repeatedly lead, perhaps connect successively by a plurality of particle layering guide thimble devices.
Nationality carries out layering by said structure in flue gas or the gas under the effect of particle layering guide thimble device, make bulky grain concentrate on the center of smoke pipe, thereby avoids the end face of abrasion of particles smoke pipe in the flue gas.Multilevel hierarchy guide thimble device is made up of a plurality of particle layering guiders and casing, repeatedly the particle in flue gas or the gas is carried out layering, makes bulky grain concentrate on the center of smoke pipe.
For guaranteeing particle layering in flue gas or the gas, on the cone of particle layering guider, offer circular hole, dwindle successively outward from interior, make bulky grain concentrate on the smoke pipe central area; On cone, also can offer trapezoidal cylindrical void, dwindle successively outward from interior.
Compared with prior art, the beneficial effects of the utility model are: the utility model is installed in the entrance of Boiler smoke tube, can be the bigger solid particle in flue gas or the waste heat gas, carry out layering and concentrate on the central area of Boiler smoke tube, prevent or alleviate wearing and tearing to Boiler smoke tube, the service life of improving Boiler smoke tube.
Below in conjunction with drawings and Examples the utility model is further elaborated.
