Haze removal device and method for spraying charged water at high altitude

Abstract

The invention provides a haze removing device and method spraying charged water high in the air. The haze removing device spraying the charged water high in the air comprises an equipment box, a spraying device, a floating-in-air carrying device and a high-voltage direct-current power source. A water tank, a high-pressure water pump and a winch device are arranged in the equipment box. The winch device comprises a winch rope cylinder and a winch motor, wherein the winch rope cylinder is used for twining a mooring rope. A high-pressure water pipe and a high-voltage wire are arranged in the mooring rope. The end, outside the winch rope cylinder, of the mooring rope is connected with the spraying device. The floating-in-air carrying device is connected with the spraying device. The high-pressure water pump conveys high-pressure water to spray nozzles through the high-pressure water pipe. The high-voltage direct-current power source enables the spray nozzles to spray out high-voltage charged water. According to the haze removing device and method spraying the charged water high in the air, in the top irrigation type charged spray manner, the haze is completely broken up from top to bottom until the PM2.5 in the haze settles to the ground, the cost is low, and the practicability is good; and through the haze removing method, stable suspension tiny solid-liquid particles in haze aerosol are made to be coagulated into large particles, under the dual action of the earth gravitational field and the static electric field, the large particles gradually settle to the ground, the haze removal efficiency is improved, secondary pollution is avoided, and environment protection and energy saving are achieved.

Description

technical field [0001] The invention belongs to the technical field of haze removal, and in particular relates to a haze removal device and method for spraying charged water at a high altitude. Background technique [0002] With the development of human society, the roughness of the earth's surface is also increasing, which makes the number of low-altitude negative ions increase significantly, and the wind speed at low altitudes weakens. Coupled with the massive consumption of petrochemical energy, the smog is becoming more and more serious, which seriously affects people's physical and mental health and national health. The healthy development of the economy has reached a critical juncture that must be governed. For this reason, numerous scientific and technical personnel have proposed various haze removal methods, sum up and mainly contain negative ion electrostatic dust removal CN104906897A, artificial wind dust removal method CN103274663A, chemical coagulant dust removal...

AI Technical Summary

Problems solved by technology

Large-scale artificial wind costs a lot of money and is poor in feasibility; the manufacture and spraying of dust-suppressing glue consumes a lot of energy and may cause secondary pollution. There are many disadvantages in large-scale application; although negative ion electrostatic dust removal can also have It has a certain effect, but it is not ideal in principle. Although the input of negative charges can destroy the stability of aerosols, the negative charges will generate electrostatic repulsion with the earth's electrostatic field that is not conducive to sedimentation. Therefore, negative ion electrostatic dust removal is not conducive to large-scale removal. Haze; the filtration method is only suitable for dust removal in a small closed space. When used outdoors, not only has little effect, but also has a huge investment and very high operating costs.

Although the patent CN201510900176.7 proposes that injecting positive charges into the air can accelerate the settlement of smog particles, the methods listed in it are not highly effective and the effect of implementation is limited.

Although the above-mentioned existing technologies can all play the role of removing haze, they are not suitable for large-scale haze removal outdoors.
