specific Embodiment approach 1

[0024] Specific implementation mode one: as Figure 1-7 , this embodiment is an evaporation crystallizer for removing oil from salty and oily wastewater, specifically composed of a cylinder body 1, a floating oil collection funnel 4 in the evaporation chamber, a baffle cone 5, a feeding collection funnel 6 in the crystallization chamber, a baffle plate 7, The crystallization chamber oil / water separation tank 16, the crystallization chamber oil / water separation tank communication pipe 17, the heat exchanger 24, the circulating pump 25, the evaporation chamber oil / water separation tank 20 and the evaporation chamber oil / water separation tank communication pipe 23;

[0025] The evaporation chamber oil / water separation tank 20 is arranged in the middle and lower part of the outside of the cylinder body 1, and the top of the evaporation chamber oil / water separation tank 20 communicates with the upper part of the cylinder body 1 through the evaporation chamber oil / water separation ta...

specific Embodiment approach 2

[0038] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the cone angle of the feed collection funnel 6 in the crystallization chamber is 100°-120°. Others are the same as the first embodiment.

specific Embodiment approach 3

[0039] Embodiment 3: The difference between this embodiment and Embodiment 1 is that: the cone angle of the first circular frustum 5 - 1 of the baffle cone 5 is 120°-150°. Others are the same as the first embodiment.

Abstract

The invention relates to an oil-removing evaporation crystallizer for waste water containing salt and oil, and relates to the oil-removing evaporation crystallizer for waste water. The evaporation crystallizer aims at solving the technical problems of bad separating and oil removing effects as well as bad long-time continuous separation and oil removal existed in the prior evaporated crystallizers. The oil-removing evaporation crystallizer comprises a cylindrical shell, a flow blocking cone, a baffle plate, a crystallization chamber oil / water separating tank and an evaporating chamber oil / water separating tank; the evaporating chamber oil / water separating tank is arranged at the middle lower part of the external part of the cylindrical shell; the crystallization chamber oil / water separating tank is arranged at the upper part of the external part of the cylindrical shell; a crystallization chamber charging collection tunnel is fixed to the middle part of an inner wall of the cylindricalshell and is sealed with an inner wall of the cylindrical shell; the flow blocking cone is arranged on a crystallization chamber floating oil collection tunnel; a first down pipe of the crystallization chamber floating oil collection tunnel is fixed in a through hole of a central axis of the flow blocking cone. The oil-removing evaporation crystallizer for waste water containing salt and oil hasthe characteristics of two stage oil removal and continuous operation, and at the same time, the product is advantageous in that the product is easy to control, separation and oil removal are not influenced by pressure fluctuation of the evaporating chamber, and normal pressure or reduced pressure evaporative crystallization can be carried out.

Description

technical field [0001] The invention relates to a waste water deoiling evaporation crystallizer. Background technique [0002] Evaporative crystallization is a common method for treating industrial wastewater (or waste liquid), in which the evaporative crystallizer plays an extremely important role in the crystallization quality and evaporation efficiency in the evaporative crystallization process, and is the key equipment in the evaporative crystallization process. [0003] In the process of evaporative concentration and crystallization of waste water (or waste liquid) containing salt and organic matter, affected by the properties of the constituent materials of waste water (or waste liquid), some waste water containing a small amount of oil or oily matter will gradually degrade as the water evaporates and the salt concentration increases. Precipitation of organic matter - oil, in the evaporative crystallizer, a crystallized and concentrated mixed liquid of oil / water / solid ...
