Embodiment Construction
[0016] refer to figure 1 Shown, air electric heating box 2 is a rectangular stainless steel casing. Inside the air electric heating box 2, the steel plates 4 welded on the box wall are staggered to divide the box body into a plurality of rectangular flow passages with the same size and connected to each other. After the air at normal temperature is sent into the air electric heating box 2 by the blower 1, under the restriction of each steel plate 4, it turns back along the curve and flows through each channel in turn, and then flows out from the outlet of the air electric heating box 2. The air circulation distance inside the air heating box 2 is increased, the time for the air to be heated is increased, which is beneficial to increasing the outlet temperature of the air and reducing the temperature of the box body itself. The two sides of the side wall of the air electric heating box 2 are provided with circular holes at equal intervals along the rectangular channel for arra...

The invention discloses an air heating device for liquid in a visual pipeline. The air heating device comprises a fan, an air heater box, a high-temperature air valve, an observation box equipped with a quartz glass observation window, a liquid pipeline, a heat preservation layer, etc. The fan sends normal-temperature air into the air heater box to be heated to increase temperature by a heating rod in the air heater box. The high-temperature air enters into the observation box through the high-temperature air valve to heat up the liquid in a quartz glass flow passage and then is discharged to the atmosphere. The air heater box, the observation box and the external parts of a liquid inlet pipeline and a liquid outlet pipeline (except the part of the observation window) are all wrapped by the heat preservation layer for heat preservation and insulation. The quartz glass observation window of the observation box can be used for observing and recording the state of the liquid in a quartz glass observation pipeline under the heating condition. The air heating device can adjust the heat flow density of the liquid heated by the high-temperature air in the observation box by changing the air output of the fan or the heating power of the heating rod.
Description
technical field [0001] The invention relates to the heating of the fluid in the visible pipeline, in particular to an air heating device for the fluid in the visible pipeline. Background technique [0002] In the field of chemical industry, a large number of chemical reactions require external heating to ensure the progress of the reaction or increase the speed of the reaction. At the same time, in order to observe and control the progress of chemical reactions in real time, some chemical reactions in the industry need to obtain sufficient external heat sources when the chemical reaction status is visible. In addition, in scientific experiments, a large number of chemical experiments that require heating need to record and observe the phenomenon of chemical reactions; It is carried out in a visualized heating pipeline to observe and analyze experimental phenomena such as flow patterns and vapor content. [0003] Patent CN201039503 describes an electrically heated glass. T...
