And there are also a small amount of dichlorosilanes to be decomposed to form ambiguity silicon at high temperature, and above-mentioned the two is deposited on electric add after being mingled with mixing
Between heat pipe, the heat transfer efficiency of electric heater is directly affected, deposition excessively causes electric heating tube local temperature excessively high when long, indirectly
Property cause electric heating tube burning melt damage.
In consideration of it, it is necessary to design a kind of electric silicon tetrachloride heater to solve the above problems.
Utility model content
Technical problem to be solved by the utility model is: providing a kind of four for prolonging the service life and improving heat utilization rate
Silicon chloride electric heater.
Following technical solution that in order to achieve the above object, the utility model provides: a kind of electric silicon tetrachloride heater, including
Mounting base, several pressure vessels being mounted in mounting base and the electric heating tube being arranged in inside each pressure vessel, it is described
Each pressure vessel is vertically mounted in mounting base, and the electric heating tube owns along each pressure vessel genesis analysis
Pressure vessel formed be connected in series, in the pressure vessel of series connection and be located at both ends pressure vessel be respectively equipped with import
And outlet, each pressure vessel are equipped with sewage draining exit.
Further, each pressure vessel further include the overtemperature thermocouple being connect with electric heating tube and with overtemperature heat
The overtemperature explosion proof instrument of galvanic couple connection.
Further, the electric heater further includes the first temperature-measuring port of the import close to pressure vessel and is arranged in institute
There is the second temperature-measuring port among pressure vessel, the inside of first temperature-measuring port and the second temperature-measuring port is equipped with temperature element.
Further, each pressure vessel is designed with a pair of of support portion with mounting base cooperation.
Further, the sewage outfalls setting is in the bottom of each pressure vessel.
Further, two adjacent pressure vessel bottoms are connected by connecting tube, and the sewage outfalls setting is even
On adapter tube.
Further, the electric heating tube is coiled pipe.
Further, several bracing rings are also arranged on the electric heating tube.
The prior art is compared, the utility model at least has the following advantages: by being transformed to existing electric heater,
Operating load is reduced, heat utilization rate is improved；Due to vertically-mounted, the portion generated after silicon tetrachloride heating of electric heater
Point silicon powder and ambiguity silicon are deposited on the bottom of pressure vessel because being acted on by gravity, and when maintenance can directly be prolonged with periodic cleaning
The service life of electric heater is grown.
