Embodiment 1

[0039] The invention is attached to the specification figure 1 And further explanation and description of the device provided by the present invention.

[0040] The present invention provides a device for concentrating low-concentration salt-containing wastewater, which is characterized in that the device includes a wind guide horn (9), an evaporation bin and a water collection trough (3); one or more wind guide horns (9) are provided Atomized water cannon nozzle (1).

[0041] The evaporation bin is a two-stage evaporation bin, including a first-stage evaporation bin (8) and a second-stage evaporation bin (5).

[0042] The first-stage evaporation chamber (8) and the second-stage evaporation chamber (5) are both composed of black porous fabric, the fabric is made of polyester, aramid, carbon fiber, nylon, polyethylene fiber, polypropylene fiber, polyphenylene sulfide fiber One or more of the weaving.

[0043] Eight atomized water cannon nozzles (1) are arranged at the junction of the...

Embodiment 2

[0050] The invention provides a use accessory figure 1 The method for treating low-concentration salt-containing wastewater in the shown device is to use a wind deflector (9) and an atomizing water cannon nozzle (1) to atomize the low-concentration salt-containing wastewater and divert it to the first-stage evaporation chamber ( 8) The main evaporation net (7) between the first-stage evaporation chamber (8) and the second-stage evaporation chamber (5) is a fabric with high moisture absorption and high air permeability, and the atomized low-concentration salty wastewater enters through the main evaporation net The second-stage evaporation chamber (5), in the evaporation chamber is a black porous fabric. After atomization, the low-concentration salty wastewater can be evenly dispersed on the black porous fabric through the effects of wicking and gravity. The black fabric can quickly use solar energy. The evaporation effect is achieved, and then the concentrated salt-containing wa...

Abstract

The invention discloses a low-concentration salt-containing wastewater concentration apparatus and a treatment method. The low-concentration salt-containing wastewater concentration apparatus comprises an atomized water cannon spraying nozzle, an air guiding horn, a first-stage evaporation bin, a main evaporation network, a second-stage evaporation bin, a secondary evaporation network, a flow guiding wing, a water collecting groove, and an annular shunt pipe. The low-concentration salt-containing wastewater concentration apparatus of the present invention has advantages of simpleness, high working efficiency and no energy consumption, and can efficiently improve the low-concentration salt-containing wastewater evaporation efficiency.

Description

Technical field [0001] The invention belongs to the field of wastewater recovery devices, and specifically relates to a low-concentration salt-containing wastewater concentration device and a treatment method. Background technique [0002] The so-called evaporation refers to the vaporization process that occurs on the surface of the liquid when the liquid temperature is lower than the boiling point, which can occur at any temperature. Factors affecting the speed of evaporation: temperature, humidity, surface area of ​​the liquid, air flow on the surface of the liquid, etc. The amount of evaporation is usually expressed in millimeters of the thickness of the evaporated water layer. [0003] At present, most of the treatment of concentrated brine at home and abroad uses evaporation ponds to evaporate naturally. The biggest reason is its energy saving and low operating costs. However, it covers a large area, requires high leakage prevention, low evaporation rate, and regional limitat...
