High-temperature fused salt storage tank device

Abstract

The invention discloses a high-temperature molten salt storage tank device, which comprises a first shell, a shock absorbing device and a second shell. The double-layer structure of the first shell and the second shell can play a role of heat insulation, reducing The heat is lost through the surface of the storage tank, which enhances the heat preservation effect. The lower part of the side wall of the first shell is provided with a discharge pipe, and the inner wall of the discharge pipe is welded with a deflector. The first shell and the second shell are connected with the discharge pipe. The connection of the pipe is provided with rounded corners, so that the discharge port forms a smooth and gradual channel to prevent the precipitated crystals from blocking the discharge port. A manhole is provided on the side wall of the first shell away from the discharge pipe. The first The top of the housing is installed with a feed pipe, a safety valve and a liquid level gauge in sequence. The bottom of the liquid level gauge extends to the bottom of the inner cavity of the second housing. A heating tube is set inside the second housing. An electric heating wire is arranged inside, and the heating pipes are arranged in a spiral shape from top to bottom along the inner wall of the second housing to increase the heat conduction area.

Description

technical field [0001] The invention relates to the technical field of chemical storage equipment, in particular to a high-temperature molten salt storage tank device. Background technique [0002] High-temperature molten salt is a molten body formed after melting salts, such as a molten body of alkali metal, alkaline earth metal halide, nitrate, and sulfate. High-temperature molten salt is solid at standard temperature and atmospheric pressure, and exists after the temperature rises. In the liquid phase, there are all kinds of storage tanks in chemical plants, but due to the particularity of high-temperature molten salt, ordinary storage tanks do not have good thermal insulation performance. After a long storage time, high-temperature molten salt will solidify and crystallize , is not well suited for the storage of high-temperature molten salt, and high-temperature molten salt is easy to crystallize and precipitate solid particles, which may easily cause blockage of the sto...

[0002] High-temperature molten salt is a molten body formed after melting salts, such as a molten body of alkali metal, alkaline earth metal halide, nitrate, and sulfate. High-temperature molten salt is solid at standard temperature and atmospheric pressure, and exists after the temperature rises. In the liquid phase, there are all kinds of storage tanks in chemical plants, but due to the particularity of high-temperature molten salt, ordinary storage tanks do not have good thermal insulation performance. After a long storage time, high-temperature molten salt will solidify and crystallize , not well suited for the storage of high-temperature molten salt, and high-temperature molten salt is easy to crystallize and precipitate solid particles, which is likely to cause blockage of the storage tank, affect the normal production, and destroy the continuity of production
