Description

CENTRAL CONTROL TYPE MIST SUPPLY DEVICE FOR EARLY STABILIZATION OF LANDFILL}

The present invention relates to a centralized water supply device for pre-stabilization of landfill, and more particularly, to inject chemical and water in the form of an aerosol to promote biodegradation of organic substances in a large area of landfill, thereby pre-stabilizing landfill. It relates to a centrally controlled water and chemical liquid supply device for induction.

According to a survey by the Ministry of Environment, Korea has 1,278 landfills in 2008 and 220 landfills in use. Many of these projects are expected to continue to be refurbished into the landfill project, which is being promoted by the Ministry of Environment, as well as the landfill project.

In addition, the 'circular landfill maintenance project' is maximizing the value of energy of discarded wastes by adding fueling process to enable not only the life of existing landfills but also the recycling of excavated combustible wastes (RDF, etc.).

In the 2010 revised and newly-used Landfill Maintenance Guidelines and Landfill Circulation Maintenance Projects, the pre-stabilization assessment (water content and biodegradability of landfill gas, flammable waste) is carried out to pre-stabilize the landfill. To judge.

In the past, the pre-stabilization method simply injects external air into the landfill and replaces the anaerobic environment with aerobic to temporarily reduce the generation of methane and odor components, and supplies leachate or effluent to induce biodegradation of organic materials. The way was done.

However, existing technologies, along with technical limitations, can cause serious problems in actual operation.

In the former case, the interior of the landfill is replaced by aerobic air due to external air and the rapid drying process reduces the occurrence of temporary methane and odor components. Cause problems such as poor quality of the product and the occurrence of odors in storage and transportation.

In the latter case, it is possible to increase the biodegradation efficiency in the landfill by supplying leachate or effluent in part, but technically, partial excess water supply and lack of moisture due to channeling during leachate or effluent supply Generated to reduce the decomposition efficiency of aerobic microorganisms of organic matter in the landfill, particularly excessive water supply can be a major threat to landfill stability.

In addition, additional facility investment is required due to the narrow impact radius, and the efficiency and economic efficiency of the leachate or effluent transport and odor generation during operation are very low.

Moreover, although the utility is recognized as a method for treating leachate or effluent, management of end-use landfill in terms of maximizing landfill utilization and recycling of landfill wastes based on the landfill circulation maintenance project and end-of-use landfill maintenance The period is rather long, and enormous energy costs are incurred to remove excess moisture in landfill waste recycling.

The present invention was created in view of the above-described problems in the prior art, and in order to solve this problem, in order to pre-stabilize the landfill injecting water and chemicals in the form of an aerosol (Aerosol) to spread as far as possible to spread the cost Its main purpose is to provide a centrally controlled water supply system for pre-stabilization of landfills, which reduces and improves the efficiency of stabilizing landfills by making them aerobic at an early stage.

According to the present invention, since the reach distance that can be spread by conveying the micro-sized water and the chemical liquid through the air is long, it is possible to supply water throughout the landfill without using a plurality of lances, and is controlled by a centrally controlled supply method. It is possible to reduce the processing cost while ensuring ease of use and efficiency.

1 is an exemplary view showing a water supply device according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is an aerosol, which has not been applied to a domestic waste landfill so far, such as water or a chemical liquid is chopped into a size of about 10 μm, more preferably at least 5 μm, and then blown into air to reach it. Is configured to increase as much as possible.

In this case, the air may be supplied with a chemical solution (including aerobic microorganisms that promote decomposition when the landfill is converted into an aerobic state) in addition to the aerosol which is the atomized water.

In addition, when spraying and supplying with air in the form of aerosol, according to the experiment, the time to reach the required water function at a distance of 10 meters is about 30 minutes, depending on the amount of aerosol supplied and the amount of air flow injected water and chemical liquid Supply could be confirmed.

Based on this, the present invention makes a fine aerosol state by dividing the water or the water and the chemical liquid finely, and by supplying the air as a conveying means at least 2-3 times the radius of water that can be supplied by at least one lance It is configured to extend the ideal.

More specifically, the water supply device according to the present invention is composed of a supply device 100, the distribution unit 200 and the injection unit 300, as shown in FIG.

At this time, the supply device 100 includes a device configuration for dividing the water or water and the chemical liquid finely, and a configuration that can be loaded in the air as a conveying means.

That is, the supply device 100 includes a blower 110 for injecting a large amount of air.

The blower 110 is a kind of blower equipment for injecting air into the supply pipe 120 through the discharge side by introducing external air.

The supply pipe 120 is connected to the distribution unit 200.

In addition, the supply device 100 also includes an aerosol generator 130.

The aerosol generator 130 is a device that makes the supplied water or water and chemical liquid into an aerosol state having a size of about 10 μm, for example, it is understood that it is similar to a humidifier using an ultrasonic vibrator.

In addition, although not shown, the aerosol generator 130 is connected to a water supply or a chemical liquid supply container.

In addition, the discharge side of the aerosol generator 130 is connected to the supply pipe 120 which is a blower pipe blown by the blower 110 through the discharge pipe 140.

In this case, when the connection portion between the discharge pipe 140 and the supply pipe 120 is configured in a venturi shape, the flow rate of the air that advances the supply pipe 120 at high speed (average flow rate of the blower is about 20 ± 10 m / sec) The suction pressure is generated at the connecting portion, and the suction pressure naturally sucks a myriad of aerosols discharged through the discharge pipe 140 into the air to be blown, and the air can be conveyed according to the air blowing speed by using the air as a conveying means. .

In addition, the opening and closing valve 150 may be further added to a part of the length of the discharge tube 140. When the opening and closing valve 150 is locked, only the air blowing through the blower 110 may be provided.

This is because the air blown by the operation of the blower 110 is a high-temperature air having a considerable amount of heat up to 80 ° C. in the summer, and only when the landfill is determined to be converted into an aerobic state, only by operating the shutoff valve 150. It can also provide the advantage of controlling only the blowing air to perform the drying function.

On the other hand, the distribution unit 200 is installed at the end of the supply pipe 120.

The distribution unit 200 includes a distributor 210. The distributor 210 has a single input and a plurality of outputs, and connects a plurality of distribution pipes 220 to one supply pipe 120 to provide a pipe water. Can contribute to reducing

That is, since the landfill is very wide, a plurality of injection lances 310 constituting the plurality of injection units 300 should be provided at regular intervals. Since there was a disadvantage in that the number of pipes was increased and the equipment was complicated because of the connection form, in the present invention, the plurality of distribution pipes having a plurality of injection lances 310 in the short distance from the distributor 210 as one starting point. By being connected to the 220 will be a form in which a plurality of injection lances 310 are connected to one supply pipe (120).

Therefore, even if only a few supply pipes 120 are provided to cover the size of the landfill within the range in accordance with the treatment plan can contribute to reducing equipment costs, labor costs, material costs and the like.

In addition, although not shown, if a separate opening adjustment valve is attached to each distribution pipe 220, partial supply control is also possible according to the local state of the landfill. Of course, this is preferable to manual control, but of course, automatic control is also possible when a control system and a solenoid valve are installed. However, since this part is not the main concern of the present invention, a detailed description thereof will be omitted.

Meanwhile, the injection part 300 includes an injection lance 310.

The injection lance 310 is a kind of pipe having a sharp bottom, and a plurality of injection holes 320 are formed over a predetermined length from the bottom.

The injection hole 320 is formed radially, one end of the distribution pipe 220 is connected to the upper end of the injection lance 310.

In addition, the injection lance 310 is driven in a predetermined depth and kept in the embedded state.

In addition, the injection lance 310 used for a predetermined time by hitting the landfill is again taken out and reused after being driven to the next stabilization place in the landfill.

The present invention having such a configuration has the following operational relationship.

First, the injection lance 310 is driven into the installation place at a predetermined position according to the landfill maintenance project.

Then, after confirming the proper position to install the distributor 210 in consideration of the flow rate and the speed and install the distributor 210.

Then, the injection lance 310 and the outlet side of the distributor 210 is connected.

In this state, the discharge tube for connecting the inlet side of the distributor 210 and the outlet side of the blower 110 to the supply pipe 120, and discharges the aerosol 130 generated from the aerosol generator 130 on the supply pipe 120 ( 140).

Here, such a work order does not necessarily mean that the order is to be performed in this order, but merely described a preferred example by way of example, the above-described configuration is interconnected to provide a structure that can be supplied with moisture or moisture and chemical liquids. You have it.

In this way, when the installation of the equipment is completed, the blower 110 is operated to blow air.

Then, the air is supplied to the distributor 210 through the supply pipe 120 at a flow rate of approximately 20 ± 10 m / sec, is distributed to the plurality of distribution pipes 220 in the distributor 210 and then supplied to the injection lance 310 In the injection lance 310, a radial injection of the injection lance 310 is performed through the injection hole 320.

At this time, a large amount of aerosol generated in the aerosol generator 130 is introduced into the supply pipe 120 through the discharge pipe 140, and is injected in the landfill with air while being conveyed by the air as a conveying means.

However, due to the nature of landfills, since the characteristics of landfills vary widely, the gaps between them also vary.

However, the aerosol burnt in the injected air has a particle size of at least 5 μm and thus spreads over a very long distance to the extent of the air.

For example, as in the previous experiment, the minimum radius of influence is 10m or more.

Therefore, the water and the chemical liquid are evenly and evenly spread over the entire landfill surface, and since it is made in a short time, the biodegradation efficiency of organic substances is promoted in an aerobic state, and thus preliminary stabilization is possible.

In addition, the dispenser 210 may be adjusted to selectively supply moisture, chemical liquid or dry air according to the stabilization state of each part of the landfill.

As described above, the water supply device according to the present invention adopts the concept of aerosol, which has not been disclosed previously, and has a system for selecting and conveying the conveying means to further widen and evenly supply the water supply radius to the landfill. It provides an excellent effect on the pre-stabilization of.
