Abstract
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.

The specific embodiment
With reference to shown in Figure 1, air electrical heating case 2 is a rectangle stainless steel casing.Air electrical heating case 2 inside are welded on the steel plate 4 on the tank wall by intermeshing, box house is divided into a plurality of measure-alike rectangular flow circulation passage that are connected with each other.After normal temperature air is sent in the air electrical heating case 2 by air blast 1, under the restriction of each steel plate 4, turn back successively along curve and to flow through behind each passage, flow out from 2 outlets of air electrical heating case.Increased the circulation distance of air, increased the time that air is heated, helped improving the outlet temperature of air, reduced the casing self-temperature in air heat case 2 inside.Air electrical heating case 2 sidewall two sides have equally spaced circular hole along rectangular channel, in order to the flow layout electrically heated rod 3 of vertical direction equal intervals of air.
With reference to shown in Figure 2, electrically heated rod 3 is the cylinder Elema.Be inserted in behind several layers of aluminium foil 12 of electrically heated rod 3 two ends parcel in the separation sleeve 13 of pottery location.By pottery location separation sleeve 13 it is stuck in air electrical heating case 2 sidewall circular hole places, makes electrically heated rod 3 and 2 isolation of air electrical heating case and play the effect of location.Between air electrical heating case 2 and the location separation sleeve 13, between location separation sleeve 13 and the electrically heated rod 3 small gap is arranged all, guarantee that the deformation that causes under the hot operation condition can not cause crisp hard silicon-carbon electrically heated rod 3 fractures.Two electrodes of power supply are clipped to aluminium foil place, electrically heated rod 3 two ends, regulate the heating power that power source voltage can change electrically heated rod 3.Silicon-carbon electrically heated rod 3 can the operating temperature with 1450 ℃ use 7000 hours in the air of dried and clean continuously, and maximum operating temperature can reach 1500 ℃.In the flow process, constantly stream high temperature silicon-carbon electrically heated rod 3 in the tortuous runner of normal temperature air in air electrical heating case 2.Behind tens of electrically heated rods 3 heat temperature raisings, in the exit of air heat case 2, air themperature can reach 400～500 ℃.
