Description

Technical Field

[0001] This utility model relates to the technical field of chlorosulfonic acid preparation and processing, and in particular to a chlorosulfonic acid production batching device. Background Technology

[0002] Chlorosulfonic acid (ClHSO3) is a key inorganic chemical raw material widely used in sulfonamide drugs, pesticides, dyes, saccharin, detergents, and military chemicals. Its production involves passing dry hydrogen chloride gas into fuming sulfuric acid containing dissolved sulfur trioxide, where it reacts directly at room temperature to produce chlorosulfonic acid. This process requires a chlorosulfonic acid production batching unit to complete the preparation of chlorosulfonic acid.

[0003] For example, in a prior art represented by application number CN202421758838.2, the main structure includes a frame, a mixing tank fixedly connected to the top of the frame, a square plate fixedly connected to the outer wall of the mixing tank, an auxiliary material bucket fixedly connected to the square plate, a feed pipe connected to the bottom of the auxiliary material bucket, the bottom end of the feed pipe connected to the mixing tank, an elastic strip fixedly connected to the inner wall of the feed pipe extending into the interior of the mixing tank, a rotating shaft rotatably connected to the mixing tank, a connecting rod fixedly connected to the rotating shaft, and an arc plate fixedly connected to the end of the connecting rod away from the rotating shaft. This high-carbonate graphite production batching device, by setting up structures such as an auxiliary material bucket, a feed pipe, an elastic strip, an arc plate, and a connecting rod, allows the elastic strip to vibrate and oscillate inside the feed pipe, accelerating the material's slippage and preventing blockage. Simultaneously, it achieves intermittent feeding, preventing excessive material accumulation and improving the batching effect.

[0004] During use, it was found that sulfuric acid gas is generated during the preparation process, which also contains some unreacted hydrogen chloride gas. Existing chlorosulfonic acid production batching equipment does not easily handle acidic gases, which affects the health of operators.
