Embodiment 1

[0054] to combine figure 1 and figure 2 , an on-line detection device for air flow in the sintering process of the present embodiment, mainly composed of a shroud 4 and an air detector 7, etc., when in use, the shroud 4 is placed on the sintering material layer in the middle of the sintering trolley The flow of air flowing through is detected by an air detector 7 . The wind deflector 4 in this embodiment is mainly composed of at least four sub-drain deflectors 5 arranged side by side. The specific number can be selected and designed according to the width of the sintering trolley 1 used. The length of the bottom of the wind deflector 4 is the same as The width of the sintering trolley 1 is matched so that the guide cover 4 covers the sintering material layer in the width direction of the sintering trolley 1 . In this embodiment, four sub-diffusers 5 are provided as an example to illustrate this solution. The four sub-diffusers 5 are arranged side by side along the same stra...

Embodiment 2

[0058] see figure 1 , figure 2 and image 3 , a kind of on-line detection device of air flow in the sintering process of this embodiment, its basic structure is the same as that of Embodiment 1, and its difference is: in this embodiment, the air guide cover 4 is composed of eight sub-air guide covers 5 arranged side by side along the same direction The inner diameter of the intake pipe 51 is D, the length of the intake pipe 51 is 16D, and the air detector 7 is installed at a position 10D away from the intake pipe 51. After many tests, it is found that the air velocity is more stable in this case, and the measurement The results are also more accurate. In addition, in order to make the air flow rate of the sintered material layer more stable, the exhaust hood provided is a rectangular hood 53 connected to the intake pipe 51 through a transition section 52. The cross section of the rectangular hood 53 is a square. It has less influence on the air velocity and is closer to th...

Embodiment 3

[0061] An online detection device for air flow in the sintering process of this embodiment has the same basic structure as that of Embodiment 2, the difference being that in this embodiment the inner diameter of the air intake pipe 51 is D, the length of the air intake pipe 51 is 18D, and the air The detector 7 is installed at a position 12D away from the intake pipe 51 . The sealing sheet is formed by continuous arrangement of flexible heat-resistant sheets 4 having the same width as the rectangular cover 53 . Due to the uneven surface of the sintered material layer, the use of the segmented sealing sheet structure is better, and the sealing performance of other parts will not be affected by the protrusion of part of the material layer. Because the surface of the sintered material layer is in contact with the air, the temperature is generally within 200°C, and the material of the flexible heat-resistant sheet 4 used is one of Metas needle felt or Flumes needle felt. If the t...

Abstract

The invention discloses a sintering process air flow online detector and a detection method thereof, belonging to the technical field of sintering. The air flow online detector is internally provided with a flow guide cover, wherein multiple sub flow guide covers are arranged in the flow guide cover side by side, air detection instruments are arranged in the sub flow guide covers, and the flow guide cover is sealed by sealing pieces at the bottom of the flow guide cover. When the sintering process air flow online detector is used, the flow guide cover is hung on a material surface of a sintering trolley, then the flow guide cover moves along with the sintering trolley, meanwhile the air detection instruments are started to perform interval detection to obtain average flow velocity and temperature parameters of air, and the aim of direct detection is achieved. The flow guide cover is simple in structure and convenient to use, air flow and the temperature parameters can be directly detected, and the accuracy of a heat balance measurement result of a sintering machine is improved by using the detection method.

Description

technical field [0001] The invention relates to the technical field of sintering, and more specifically relates to an online detection device and a detection method for air flow in a sintering process. Background technique [0002] Sintering is the leading production process of iron ore powder agglomeration in my country, and it is an important part of the entire iron and steel production process. The material handling capacity of the sintering process ranks second in the iron and steel complex, second only to blast furnace ironmaking, and the energy consumption ranks third only to ironmaking and steel rolling. It is the material flow, energy One of the processes with the largest flow rate. Reducing the energy consumption of the sintering process is an important topic in sintering production and an important way to reduce the cost of sintering ore. In the sintering process, heat energy consumption accounts for about 80%, which is the main direction of energy conservation. ...
