KR200219754Y1 - Water removal device of sludge using high frequency and infrared - Google Patents

Abstract

(1) The technical field to which the invention belongs

The present invention almost completely removes moisture contained in sludge or food waste with high moisture content by using high frequency and infrared light.

(2) Purpose of devising

The cost of treatment (incineration and landfill) due to the high water content sludge or the secondary pollution, that is, the leachate from landfill are all the wastewater from the high water content sludge. To solve this problem, minimize the water content of sludge. It is easy to incinerate, transport and landfill to reduce cost and to prevent leachate from landfill.

(3) constitution

In the case of wastewater sludge, the water content is 75% on average, and in order to lower it to 5% or less (incineration water content), water contained in the sludge should be removed. Most of existing methods remove moisture by the compression (press) action. Since the sludge is about 73%, sludge is introduced into a vessel equipped with high frequency and infrared rays, and in the second vessel, when the water contained in the sludge evaporates and vaporizes, it is exhausted by the ventilator and the sludge is dried at a high speed. It is composed of a process that is transformed into particles and transferred to the outside by the operation of a conveyor (conveyor).

(4) effect of design

High-speed drying of all sludges with high water content allows for a wide range of applications such as sewage treatment plants, water purification plants, food waste treatment plants, and various industrial wastewater sludges.

Description

Water removal device of sludge using high frequency and infrared light {.}

Sludge is generated in a relatively clean water treatment plant, and waste water is generated in large quantities. According to the conventional processes currently being processed, most of them are compressed by pressing (compressor) to remove water contained in the sludge. It is a big problem of the conventional method that it takes up to 2% pollution and separate leachate treatment costs such as excessive water treatment cost, incineration and landfill costs, and leachate in landfill, due to the moisture content of over 73%. Water content can be reduced to less than 5% by using both infrared and infrared light, which reduces the amount of sludge to 1/4, which saves incineration and landfill costs proportionately.

When the high frequency and infrared rays are installed in the sludge drying container and the high frequency is irradiated to the sludge, the present invention is dried from the inside of the sludge particles containing moisture (exothermic temperature 130 ℃ ~ 200 ℃), and infrared rays also penetrate deep into the particle surface. When combined with high frequency and infrared light, it shows excellent drying synergistic effect and the drying speed is more than 5 times faster than the existing method. At this time, the vaporized vapor is vaporized and exhausted to the outside by the ventilator, and the sludge is dried at high speed, so the moisture content is lowered to 5% or less. The sludge amount is greatly reduced (approximately 1/4) so that it can escape from the incineration and landfill costs and the secondary pollution (leachate), and the magnet is removed to remove the metallic material before the sludge is introduced to prevent damage to the high frequency function.
