Description

Mobile Module type Waste Treatment Apparatus Using the Subcritical Water}

The present invention relates to a mobile module type subcritical waste treatment device, and more specifically, to a mobile module type subcritical waste treatment device having an improved structure so that the configuration of the subcritical waste treatment device can be configured inside a movable container.

Human beings have been developing in the direction of improving the quality of life according to changes in the socioeconomic or cultural environment.

Energy consumption is essential in this process of development, and various types of waste are generated in the process of consuming energy and living.

In addition, fossil fuels are an indispensable energy resource in modern society, but fossil fuels are created through several generations and cannot be reproduced, so there is a limit to the amount that can be used, and substances generated when burning them cause environmental pollution, so they can be replaced. [0003] Research on an energy source to be done has been conducted for a long time.

In addition, various methods for processing and recycling waste are being devised.

One of these waste treatment methods is hydrolysis of waste using subcritical water.

Water is liquid at room temperature and below atmospheric pressure, and boils to gas at 100℃ below atmospheric pressure (1 atm). , and the state right before this critical point is called subcritical water.

Water is ionized by collisions of water molecules even at room temperature/atmospheric pressure, and as the temperature rises, the frequency of collisions between water molecules increases and ionization proceeds. Hydroxide ions (OH-) are generated by this ionization, and their concentration becomes very high in critical water. This hydroxide ion creates subcritical amino acids through the peptide bonds of proteins, and lipids and carbohydrates are subcriticalized into fatty acids, respectively, in the same mechanism.

Various methods of treating waste using this principle have been proposed.

However, it is desirable to implement a treatment system capable of stably treating and recycling various types of waste while having a more effective structure.

In addition, it is preferable to make the treatment system portable so that pilot tests can be easily performed, small-sized treatment can be performed on site, and removal is easy, and time and costs associated with installation, removal, etc. can be reduced.

At the same time, high-temperature, high-pressure steam heated in the steam supply unit 100 is supplied to the tank body 1110. The temperature and pressure inside the tank body 1110 also reach the subcritical region, which is the set pressure, by the steam supplied for a set period of time, and the treatment of the waste, which has been slowly decomposed before that, is completed as the period elapses. Of course, this treatment time is different depending on the type, property, capacity, etc. of the waste.

When the treatment of the waste is completed, the steam outlet 1164 is slowly opened to remove the pressure of the tank body 1110. Since the internal pressure of the tank body 1110 is very high, a large amount of steam is discharged to the outside, and odors generated during the waste treatment process are discharged together with the steam. It is preferred that these effluents can be deodorized from the water by directing them to the water if necessary. A cyclone or the like can be used as needed.

When the pressure inside the tank body 1110 decreases and becomes atmospheric pressure, the lower treated material discharge port 1162 is opened to accommodate the treated material in a receiving means capable of accommodating the treated material, and the received treated material goes through the following process as necessary. can be recycled

In addition, when the waste treatment device 1000 according to the present invention is applied, the energy required for treatment is only fuel (kerosene, heavy oil) and water (subterranean water available) required for the boiler, and low-cost electricity, and the treatment cost is 30 per kg. It is possible to realize a low operating cost of about ~40 won.

In addition, although it differs depending on the type of waste, it was found that the waste treatment ability can realize very good performance compared to the cost of treating 1 to 6 tons of treatment objects per time in only 30 to 40 minutes.

In addition, the treated material finally discharged has water and solids, but the solids are hydrolyzed products, and when treated with enzymes, it can be used for various purposes including fertilizers and fertilizer additives very effectively, which is environmentally friendly. can
