Abstract
The utility model discloses a heating furnace spoiler, which comprises an arc-shaped plate body, wherein through holes with different diameters are alternately arranged on the plate surface of the plate body. Compared with the traditional technology, the utility model has the advantages of simple structure, scientific and reasonable design, more uniform smoke passing distribution, controllable combustion efficiency and short whole combustion time under the condition of not reducing the flow velocity of the smoke.
Description
Technical Field
The utility model belongs to the field of environmental protection, and particularly relates to a heating furnace spoiler.
Background
In the fields of metallurgy and chemical industry, a heating furnace (also called a hot blast furnace) is needed, for example, in the process of smelting steel, a waste gas incineration heating furnace is arranged between a reduction furnace and an oxidation furnace and is used for incinerating the tail gas of the reduction furnace, the tail gas of the reduction furnace has a lower heat value, a coke oven fuel is used as a supplementary fuel, and hot flue gas generated after the two gases are combusted is sent into the oxidation furnace and is used as a heat source of the oxidation furnace.
The main heat energy source for the combustion of the flue gas is provided by a burner which is connected with an air pipe and a fuel pipe, so that the end part of the burner is combusted to generate heat energy, and meanwhile, the flue gas firstly enters a flue and then is combusted at the burner. In order to ensure the uniformity of the temperature of the flue gas and the stable combustion of the fuel gas, a spoiler is additionally arranged in the flue, the traditional spoiler is a sheet-shaped plate with the same sectional area as the flue, is additionally arranged in the circumference of the flue, and the flue gas passes through the traditional spoiler at a constant speed through holes formed in the surface of the traditional spoiler. However, the design is added in the flue before the burner, and the design of the flat plate can cause particles in the partially reflected flue gas to obstruct the overall flow velocity of the flue gas and influence the uniform distribution of the flue gas.
Disclosure of Invention
The purpose of the utility model is as follows: the utility model aims to overcome the defects of the prior art and provide a spoiler of a heating furnace, which enables smoke to be uniformly distributed and does not excessively influence the flow velocity of the smoke.
The technical scheme is as follows: in order to achieve the above object, the present invention is specifically accomplished by: a heating furnace spoiler comprises an arc-shaped plate body, wherein through holes with different diameters are alternately arranged on the plate surface of the plate body.
Preferably, the plate surface of the plate body is provided with a plurality of rows of through holes, the diameter of each row of through holes is the same, and the diameter of the adjacent rows of through holes is different.
Furthermore, a plurality of rows of through holes are formed in the plate body, the diameter of each row of through holes is the same, the diameter of the through hole in the center of the plate body is the largest, and the diameters of the through holes extending to the two sides are reduced in sequence.
Has the advantages that: compared with the traditional technology, the utility model has the advantages of simple structure, scientific and reasonable design, more uniform smoke passing distribution, controllable combustion efficiency and short whole combustion time under the condition of not reducing the flow velocity of the smoke.

FIG. 2 is a schematic diagram of the impact of the flue gas particles of the present invention.
Detailed Description
Example 1:
as shown in fig. 1, the spoiler for the heating furnace comprises an arc-shaped plate body, wherein a plurality of rows of through holes are formed in the plate body, the diameter of each row of through holes is the same, the diameter of the through hole in the center of the plate body is the largest, and the diameters of the through holes extending to the two sides are reduced in sequence.
When the utility model works specifically, the spoiler is placed on the flue between the flue gas and the burner, when particles in the flue gas impact on different arc surfaces of the spoiler, different reflection directions occur, the reflection of the particles can influence the flow of the flue gas, especially, the particles on the front side are reflected in the original path, so the influence of the flow velocity of the flue gas from the path is the largest, a through hole with large aperture is formed in the center of the spoiler, the influence of the flow velocity on the flue gas in other directions is smaller, and the aperture of the through hole corresponding to the directions is smaller. When the whole flue gas passes through the guide plate, the speed still tends to be consistent and evenly distributed.
