Abstract
The utility model discloses an abrasion-resistant device of an air pre-heater. The abrasion-resistant device of the air pre-heater comprises a pre-heater pipe, wherein an abrasion-resistant casing pipe is arranged at the upper end of the pre-heater pipe in an inserted mode, pipe boards which are symmetrically arrayed are arranged on both sides of the pre-heater pipe, a cushion block is arranged between each pipe board and the abrasion-resistant casing pipe, the number of the cushion blocks is two, and the cushion blocks are symmetrically arrayed on both sides of the abrasion-resistant casing pipe. The abrasion-resistant device for the air pre-heater is simple in structure and low in manufacturing cost. When the abrasion-resistant device for the air pre-heater is used, the abrasion-resistant device is arranged at the position of an inlet of the pre-heater pipe of the pre-heater. Due to the function of air abrasion, when the abrasion-resistant device is examined and repaired, only the abraded abrasion-resistant device needs to be replaced, time and labor are saved, and resources are saved.
Description
Technical field
The utility model relates to a kind of shoe, relates in particular to a kind of air preheater shoe, belongs to the boiler plant technical field.
Background technology
Flue gas ejects from the economizer coiled pipe that to enter before the preheater flow velocity in empty flue lower, and when entering the economizer bank of preheater, because flow area reduces suddenly, the flue gas a fluid stream shrinks in advance, expansion then, and be tending towards normal gradually; Flue gas a fluid stream inwall to preheater tube when expansion produces wearing and tearing, and the department of wearing and tearing is about mouth of pipe 2-3 times of caliber place from preheater.Existing air preheater needs periodic replacement because the mouth of pipe of preheater often is worn, waste resource, time-consuming, effort.
The utility model content
In order to solve the existing weak point of above-mentioned technology, the utility model provides a kind of air preheater shoe.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of air preheater shoe, comprise preheater tube, and the upper end of preheater tube is plugged with an Antiwear casing; The both sides of preheater tube are provided with the tube sheet of a symmetry arrangement; Be provided with cushion block between tube sheet and the Antiwear casing; Cushion block is two, and symmetry arrangement is in the both sides of Antiwear casing.
The utility model is simple in structure, cost is low, and use is the import department of device at the preheater tube of preheater, owing to the effect of air abrasion, only need change the shoe that is worn during maintenance and get final product, and is time saving and energy saving, helps resources conservation more.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. preheater tube; 2. Antiwear casing; 3. cushion block; 4. tube sheet.
The specific embodiment
As shown in Figure 1, the utility model comprises preheater tube 1, Antiwear casing 2, cushion block 3, tube sheet 4.
The upper end of preheater tube 1 is plugged with an Antiwear casing 2.The both sides of preheater tube 1 are provided with the tube sheet 4 of a symmetry arrangement.Be provided with cushion block 3 between tube sheet 4 and the Antiwear casing 2.Cushion block 3 is two, and symmetry arrangement is in the both sides of Antiwear casing 2.
The utility model is simple in structure, can effectively avoid the wearing and tearing with heat pipe 1, and it is convenient to change, and has saved resource.
