[0002] Heat exchangers are common equipment in chemical, petroleum, power, food and many other industrial sectors, and they play an important role in production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are more widely used.

[0003] Generally, heat exchangers are divided into liquid media and air media. For liquid media, the current heat exchange efficiency can be understood by direct temperature measurement. However, due to the particularity of gas media, the direct measurement effect is poor and the accuracy requires repeated measurements to meet the requirements. During the detection process, the machine is usually shut down to connect the detection device to the air supply pipeline. The overall process is also relatively cumbersome. In addition, various situations may occur during the connection process between the detection equipment and the air supply pipeline, posing certain safety hazards. Utility Model Content

However, due to the particularity of gas media, the direct measurement effect is poor and the accuracy requires repeated measurements to meet the requirements. During the detection process, the machine is usually shut down to connect the detection device to the air supply pipeline. The overall process is also relatively cumbersome. In addition, various situations may occur during the connection process between the detection equipment and the air supply pipeline, posing certain safety hazards.

[0007] The utility model provides a heat exchange efficiency detection device for a chemical production line.

[0008] Furthermore, the T-shaped tube includes a horizontal part and a vertical part, wherein a spherical bin is provided at the connection between the horizontal part and the vertical part.

[0009] Furthermore, the control ball is a spherical structure with three openings on its inner hollow surface adapted to the T-tube pipeline, a control shaft on its surface extends through the T-tube to the outside, and a key groove is provided on the surface of the control shaft.

[0010] Furthermore, the heat conducting grid is arranged on the inner wall of one side of the horizontal part of the T-shaped tube away from the spherical bin, and is composed of a plurality of copper thin plates and adapted to the shape of the inner wall of the T-shaped tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

First, when the two openings of the control ball are connected to the vertical part and the horizontal part of the T-tube, the hot air can be directly discharged from the T-tube. When detection is required, the operator can use the rotating handle adapted to the keyway on the surface of the control shaft to rotate the control ball connected to the control shaft, so that the control ball is rotated until the three openings are all adapted to the T-tube. At this time, the hot air in the T-tube first passes through the control ball and contacts the thermal conductive grille.

The operator can obtain the heat exchange efficiency of the current heat exchanger by observing the information processing device. The overall process is simple and fast. After the detection is completed, it is only necessary to rotate and reset the control ball through the control shaft. There is no need to repeatedly disassemble and assemble the detection device. The overall process is simple and fast, avoiding safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

The inner wall of the horizontal part of the T-shaped tube 1 away from the spherical warehouse 2 is composed of multiple copper thin plates and adapted to the shape of the inner wall of the T-shaped tube 1. The end of the T-shaped tube 1 close to the thermal conductive grille 5 is sealed. A thermal conductive tube 6 is inserted into the thermal conductive grille 5. Two thermal conductive tubes 6 are inserted into the thermal conductive grille 5. The two thermal conductive tubes 6 pass through the surface of the T-shaped tube 1 and extend to the outside to be connected to the information processing device 7.
