Abstract

The invention relates to an anti-wall-sticking efficient vacuum concentration device and an application thereof. The anti-wall-sticking efficient vacuum concentration device comprises an evaporation chamber, a circulating delivery pump, a gas-liquid separator, a condenser, a liquid collector, a vacuum pump and a heat source supply device, the circulating delivery pump is used for circulating a to-be-concentrated solution flowing out of the bottom of the evaporation chamber to the circulating solution inlet in the top of the evaporation chamber, the evaporation chamber is provided with a liquidlevel monitoring part and a heat exchange jacket, the heat exchange jacket is divided into at least two cavities which are distributed from top to bottom by partition plates, each cavity is independently provided with a heat source inlet and a heat source outlet, and the liquid level monitoring part is used for monitoring the liquid level in the evaporation chamber and controlling opening and closing of the heat source inlet and the heat source outlet. According to the anti-wall-sticking efficient vacuum concentration device, the wall sticking phenomenon of materials can be reduced while thevacuum concentration efficiency is improved without a stirring device, the structure is simple, the energy consumption is low, and the quality and the activity of a concentrated product are improved.

Description

technical field [0001] The invention belongs to the technical field of concentration, and relates to a vacuum concentration device, in particular to a high-efficiency vacuum concentration device with an anti-sticking wall. Background technique [0002] In the pharmaceutical, food and chemical industries, it is often necessary to concentrate the feed liquid. Vacuum decompression concentration is a common concentration equipment. The existing vacuum decompression concentrator mainly includes components such as an evaporation heating tank, a condenser, a gas-liquid separator, and a liquid receiving tank. The outer wall of the evaporation heating tank is provided with a jacket, and high-temperature steam is introduced into the jacket for The feed liquid is heated, and the vacuum in the evaporation heating tube lowers the boiling point of the feed liquid, so that the feed liquid is vaporized at a lower temperature. However, the traditional vacuum concentration device has the pro...
