[0001] The utility model relates to a chemical liquid and liquid vaporization heating technology, in particular to a quartz heater, specifically a quartz graphite heater. Background Art
[0002] At present, in the field of chemical liquid heating, quartz cylindrical heaters are mostly used, such as Chinese Patent 2024105243465 discloses a quartz heating device, and Chinese Patent 2023113609568 discloses a quartz heating cylinder. They generally have low heat exchange efficiency, slow temperature rise, uneven heating and pipeline blockage, and cannot control the heating power in real time. Improvements must be made. Utility Model Content
[0003] The purpose of the utility model is to design a quartz graphite heater with high heat exchange efficiency, compact structure, less heat dissipation, fast heating and real-time accurate control of heating power, in view of the problems of low heating efficiency, slow heating, uneven heating and easy pipe clogging in the existing single quartz tube heater.
[0004] The technical solution of the utility model is:
[0005] A quartz graphite heater comprises a quartz tube 3 and a graphite cylinder 5, and is characterized in that: a plurality of through holes 6 for passing the quartz tube 3 are provided in the graphite cylinder 5, and both ends of the quartz tube 3 pass through the through holes and are respectively connected with a quartz liquid inlet sealing head 1 and a quartz liquid outlet sealing head 8, the quartz liquid inlet sealing head 1 is provided with a liquid inlet 2, and the quartz liquid outlet sealing head 8 is provided with a liquid outlet 7, and a heating film 4 is wrapped on the surface of the graphite cylinder 5.
[0006] The graphite tube 5 and the quartz tube 3 are tightly matched, and the quartz tube is wrapped in the graphite tube.
[0007] The heating film 4 is connected to a voltage regulating circuit or a PID control circuit to achieve adjustable output power.
[0008] Beneficial effects of the utility model:
[0009] The utility model heats by installing a heating film on the outer surface of graphite. The thermal conductivity of graphite is high, and the temperature can be quickly increased. Quartz is in contact with the medium. The quartz has a stable structure and chemical properties and is not easy to fall off. Therefore, it is not easy to react with the medium during the heating process and no particulate matter will be generated. The outside of the quartz component is wrapped with a graphite component, and a heating film is installed on the graphite surface. The heating film can use voltage regulation or PID to control the actual output power, so the equipment can accurately control the power.
[0010] Compared with common chemical liquid heaters, the utility model has smaller size, lower cost, more compact structure, and less floor space, and can be used in occasions with narrow areas.
[0011] The utility model is provided with a plurality of heating quartz tube channels, the medium flows more evenly, and is in even contact with the graphite on the outer surface, thus ensuring the uniformity of the medium temperature rise. BRIEF DESCRIPTION OF THE DRAWINGS
