To solve the technical problem is aimed at the deficiency of the existing technology, provide a tantalum heater, make it in the place where contact with strong acid with high thermal conductivity, and thinner tantalum material, and in the heat the gas side USES the low cost of materials, and the heater in the heating process is fully enclosed, can continuous heating, its simple structure, reasonable design, effectively improve the utilization rate of energy consumption, not only significantly reduces the manufacturing cost, and ensure the corrosion resistant performance and reliability of the heater, has the strong promotion of use value.
In order to solve the above technical problems, the technical solution adopted by the utility model is a tantalum heater which comprises a heated gas inlet into the mouth, an upper inlet pipe and a lower outlet pipe of condensate; The lower part of the heating gas outlet is provided with an outlet pipe of the gas body, which is connected with the heating gas into the mouth through a stainless steel tube plate. The stainless steel tube plate is provided with an insert pipe hole; Tantalum-stainless steel composite plate is arranged between the heated gas outlet and the vessel containing strong acid to be heated, and a heat pipe hole is arranged on the plate; The heating tube is a tantalum tube. One end of the heating tube is connected with the heating gas through the heating tube hole and the other end is arranged in the container and the end is closed. The transition pipe is arranged between the tantalum-stainless steel composite plate and the heating pipe; One end of the insert tube is connected with the heating gas into the mouth through the insert tube hole. The insert tube passes through the insert tube hole, the heating gas comes out of the mouth and the heating tube hole, and is inserted and extended in the heating tube; A plurality of baffles, which support and fix the heating tube, are provided with a baffle port, and a distance bar is arranged between adjacent baffles;
The positioning rod is arranged between the insertion tube and the heating tube and a gas flow passage is formed between the insertion tube and the heating tube. According to the utility model, on the other hand, the tantalum-stainless steel composite plate comprises a stainless steel layer and a tantalum layer, and the crossing pipe is expanded with the stainless steel layer of the tantalum-stainless steel composite plate, and welded with the tantalum layer of the tantalum-stainless steel composite plate, and the transition pipe is connected with the heating pipe by expanding welding. According to the utility model, on the other hand, the insertion tube is concentric with the heating tube. According to the utility model, on the other hand, the other end of the insert pipe is opened. According to the utility model, on the other hand, the transition pipe is a tantalum pipe. According to the utility model, on the other hand, a part of the insert pipe is inserted into the heating pipe, and the part of the insert pipe is provided with a gas hole. According to the utility model, on the other hand, the insert pipe is a stainless steel pipe.
