Hydrogen fluoride heater

Abstract

The invention relates to a hydrogen fluoride heater. The technical proposal is as follows: a sealing end of an inner cylinder is connected with a cylinder body of the inner cylinder, the cylinder body of the inner cylinder is connected with a flat cover, a fixed stiffened plate is arranged in the sealing end of the inner cylinder, a condensate outlet pipe is extended out of the inner cylinder, a steam inlet is arranged on the flat cover, and a supporting stiffened plate, a strengthening stiffened plate and a grid are arranged out of the cylinder body of the inner cylinder; the sealing end of a container is connected with the cylinder body of the container, the cylinder body of the container is connected by a flange, and the cylinder body of the container is connected with an annular plate; the sealing end is provided with a hydrofluoric acid outlet, and the cylinder body of the container is provided with a temperature measuring port, a hand hole, a liquid inlet and a hydrogen fluoride gas outlet; the inner cylinder and the container are connected with the supporting stiffened plate by the annular plate; the supporting stiffened plate is arranged in the cylinder body of the container, a packing supporting ring is arranged on the supporting stiffened plate, a packing Raschig ring is filled between the cylinder body of the container and the cylinder body of the inner cylinder on the packing supporting ring, and a distributor is arranged on the inner wall of the cylinder body of the container; the sealing end of a jacket is connected with the cylinder body of the jacket, the cylinder body of the jacket is connected with the cylinder of the container, and the steam inlet and a steam outlet are arranged on the cylinder body of the jacket. The hydrogen fluoride heater has low cost and good heat exchange effect.

Description

Technical field: [0001] The invention relates to a hydrogen fluoride heating device used in the fluoride salt industry. After the hydrofluoric acid passes through the device, the hydrogen fluoride gas escapes from the hydrogen fluoride gas outlet. Background technique: [0002] Prior to this, the hydrogen fluoride heater was imported from abroad along with the complete set of aluminum fluoride production line equipment, and the cost was high; there was no reinforcing rib on the inner cylinder, and the heat exchange effect was not ideal; the ring was thick and wasted material. The material of the container cylinder and the inner cylinder is Monel400 nickel-copper alloy, which is not ideal for heat resistance. Summary of the invention: [0003] In order to solve the above problems, the present invention provides a hydrogen fluoride heater with low cost and good heat exchange effect. The technical scheme adopted by the invention is: a hydrogen fluoride heater: composed of three part...
