Embodiment Construction

[0026] Below in conjunction with accompanying drawing real and give examples

[0027] The present invention provides a self-condensing multi-stage cross-circulation air humidification and dehumidification salt water treatment device for desalinated matter, and its internal main devices include: fan 1, heat source water tank 2, humidification filler 4, dehumidification filler 6, liquid distributor 7, foam catcher 8. Air return pipe 9, brine circulating water pump 11, fresh water cooling tank 12, fresh water circulating water pump 13, cooling coil 15, main air duct 17.

[0028] Wherein the fan 1 sends the circulating air laterally into the humidification chamber through the single-layer mist catcher 8 . The liquid distributor 7 is located above the interior of the humidification chamber, and the feed containing brine passes through the external heat source water tank 2 and then is sprayed by the liquid distributor 7 and flows into the humidification filler 4 below. The circulat...

Abstract

The invention discloses a device for treating salt-containing water by self-condensation and multi-stage cross-circulation of a desalination substance and humidification and dehumidification of air, belonging to the technical field of salt-containing water treatment. The device comprises the following main components: a fan, a heat-source water box, a liquid distributor, a humidification filling material, a dehumidification filling material, a bubble trap, a fresh water cooling box, a circulating water pump, etc. According to the invention, fed salt-containing water stepwise passes through thefresh water cooling box to recover sensible heat of fresh water and is further heated by the heat-source water box; heated salt-containing water is sprayed into the upper end of the humidification filling material through the liquid distributor and exchanges heat with humid air blown from the side surface of the humidification filling material to produce hot humid air; the hot humid air passes through the dehumidification filling material and exchanges heat with cold fresh water flown from the upper end of the dehumidification filling material to become cold humid air; thus, by utilization ofdifferent absorption capacities of humid air to water at different temperatures, fresh water is produced. The humid air is circulated respectively through a humidification chamber and a dehumidification chamber under the action of the fan. The fresh water in the dehumidification chamber flows into the fresh water cooling box from a pipeline located below the dehumidification chamber; a part of the fresh water is recirculated after being cooled; and concentrated salt-containing water in a humidification chamber of a previous stage enters a humidification chamber of a next stage for reutilization.

Description

technical field [0001] The invention belongs to the field of brine treatment. Specifically, it is a desalinated material self-condensing multi-stage cross-circulation air humidification and dehumidification salt water treatment device. Background technique [0002] Salt water mainly includes seawater, agricultural non-metallic sewage, and industrial wastewater containing heavy metals. The total amount of water resources in my country is about 2.8 trillion cubic meters, ranking sixth in the world, but the per capita water volume is only equivalent to 1 / 4 of the world's per capita share, ranking 109th in the world. The main continental coastlines in the east and south of China are as long as 18,000 kilometers, and the inland sea and coastal waters cover an area of ​​about 4.7 million square kilometers, but these salty waters cannot be used directly. At the same time, with the development of industry and agriculture in our country, due to insufficient attention to environment...
