Embodiment Construction

[0045] Such as figure 1 As shown, the embodiment of the evaporation and crystallization salt production equipment of the present invention includes: a circulation pipeline 10 , a circulation pump 20 , a heating device 30 , a flash tank 40 , and a salt washing leg 50 .

[0046] The circulation pipeline 10 is arranged vertically and has a roughly U-shaped structure. The two vertical arms are sealed and connected to the flash tank 40 respectively. Circulation flow within flash tank 40 . A waste water inlet 11 and a mother liquor separator 12 are arranged on the first vertical arm, and the waste water inlet 11 is located below the mother liquor separator 12 . The waste water inlet 11 is used to input the waste water to be extracted into the circulation pipe 10, and the mother liquid separator 12 is used to discharge the waste water mother liquid obtained after the salt is extracted.

[0047] The heating device 30 is arranged on the second vertical arm of the circulation pipeline...

Abstract

The invention provides a wastewater treatment system and evaporative-crystallization salt making equipment for treating high-salt organic wastewater. The evaporative-crystallization salt making equipment comprises a flash tank; the flash tank is provided with a first circulating water inlet and a circulating water outlet which is arranged below the first circulating water inlet; the circulating water outlet is connected with the first circulating water inlet by a circulating pipe; and the circulating pipe is provided with a heating device. The evaporative-crystallization salt making equipment further comprises a salt washing leg, and the salt washing leg is connected with and penetrates through the bottom of the flash tank and comprises an upper water inlet, a middle water inlet and a salt outlet, wherein the upper water inlet is arranged in the salt washing leg, the water inlet direction of the upper water inlet is downward, the middle water inlet is arranged below the upper water inlet and is designed to enable the wastewater in the salt washing leg to generate rotational flow, and the salt outlet is arranged below the middle water inlet. The wastewater treatment system and the evaporative-crystallization salt making equipment can be used for washing the crystalloid salt particles repeatedly under the condition that the crystalloid salt particles are mixed with the wastewater, are simple in structure, low in cost, high in wastewater treatment efficiency and can ensure that the obtained crystalloid salt particles have high purity.

Description

technical field [0001] The invention relates to an evaporation crystallization equipment and a wastewater treatment system for treating salt-containing organic wastewater; more specifically, the invention relates to an evaporation crystallization salt production equipment and a wastewater treatment system for treating high-salt organic wastewater. Background technique [0002] In various large-scale industrial production, such as petroleum refining, coal chemical industry, electric power, fine chemical industry, printing and dyeing, and pharmaceuticals, a large amount of salt-containing organic wastewater will be produced. Since my country is a country with extreme shortage of water resources, these wastewaters are usually required to be reused. However, after these wastewaters are reused, a small amount of high-salt organic wastewater will be produced. The wastewater mainly contains various inorganic salts and organic matter and other pollutants. . Because these high-salt w...
