Brine crystallizing salt-manufacturing apparatus

Abstract

A brine crystallizing salt-manufacturing apparatus comprises a crystallizing pond, brine, a brine inlet trench, a brine drainage trench and a rainproof device, and is characterized in that the crystallizing pond is arranged in a plastic greenhouse; the greenhouse body and the crystallizing pond are combined to form a stable, large-scan, high-space, tightly sealed, full-daylighting solar greenhouse capable of manufacturing salts all throughout the year; and the greenhouse is provided with a heat retaining, ventilating, moisture exhausting, water collecting device advantageous for manufacturing salts. The yield and quality of crude salt are greatly improved and fresh water can be recovered, thereby being especially suitable for production of natural salts such as natural sun-baked refined salt, sun-baked pickling salt, low-sodium salt, industrial salt and the like; and old brine drained from a saltern can be collected for reutilization; and therefore, energy sources and land resources are saved and environmental protection can be realized.

Description

technical field [0001] The invention relates to a brine crystallization salt making device. Background technique [0002] Our country has a long history of using seawater to make salt. As early as 4000 BC when Emperor Yan, there was a Susha family who boiled seawater into salt, that is, decocted salt with stew. In the struggle to understand nature and choose nature, after a long history, sea salt production has finally made a breakthrough, which is to change frying to drying. At the end of Ming Dynasty and the beginning of Qing Dynasty, people began to use mud ponds to dry salt, which is called natural salt. The evaporation pool is composed of neatly arranged salt fields. After being exposed to wind and sun, the brine is gradually concentrated to saturation, and then crystallized into salt. [0003] In the 1970s and 1980s, plastic thatch pool crystallization technology was widely used in our sea salt production, and rain-proof facilities were added, which made a new leap i...

Problems solved by technology

For edible salt, the original salt must be crushed and washed, clarified and filtered, and then heated in a boiler to remove water and processed into edible salt. This method not only wastes a lot of energy, but also emits a large amount of carbon dioxide, causing pollution to the atmosphere.
