Constant-humidity water curtain filtering system

Abstract

The invention discloses a constant-humidity water curtain filtering system, which comprises a case, a water tank, a water curtain device, a cylindrical type air duct, a motor, a fan, an air inlet andan air outlet, wherein the case is of a tube with the hollow inside; the air inlet is formed in the side wall of the lower part of the case; the air outlet is formed in the side wall of the upper partor the top; the base is sealed; the water tank is arranged at the lower part inside the case; water is contained in the box; the water curtain device is arranged in the middle inside the case and above the water tank; the lower end of the water curtain device extends into the water tank; the lower edge is lower than the upper edge of the water in the water tank; the water curtain device is a conebody with the thicker upper side and the finer lower side; the inside is hollow; a plurality of spiral projected ribs are arranged on the inner wall; a plurality of through holes are also formed in the wall of the water curtain device and between the adjacent ribs; the through holes are divided into upper layer through holes and lower layer through holes; the lower layer through holes are water mist holes; the upper layer through holes are big water drip holes; the cylindrical type air duct is arranged in the middle part inside the case and on the outer periphery of the water curtain device,and extends into the water tank; the lower edge is higher than the upper edge of the water in the water tank; the motor is electrically connected with the water curtain device; the motor drives the water curtain device to rotate; the fan exhausts air to the outside.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to a constant humidity water curtain filtration system for filtering air with water. Background technique [0002] At present, air pollution caused by environmental damage and industrial waste gas has become a major problem facing our country. The "dust" in spring and summer and the "smog" in autumn and winter have seriously endangered people's health. In particular, winter smog is known as the "winter killer". Coupled with industrial waste gas, vehicle exhaust, coal combustion and other air pollutants such as fine dust, suspended particles, bacteria and viruses, the PM2.5 index in the atmosphere seriously exceeds the standard. Therefore, air filters have emerged as the times require, and are widely used in air filtration and purification in homes and offices. [0003] The applicant filed an invention patent application named "A Multilayer Water Curtain Filtration System" on April 28...

Problems solved by technology

[0004] However, the filter system using water as the filter medium cannot control the air humidity after filtration, thus causing the indoor air humidity to rise, exceeding the appropriate range, and affecting the user's comfort
