Description

Internal Gas Treatment System in Composting Facility}

The present invention relates to a system for treating internal gas in a composting chamber, and more particularly, after separating particulate matter and moisture from internal gas in a composting chamber, the degree of contamination of which increases according to sealing of a composting facility, by rotation and collision of a conical part, It dissolves and cleans gaseous substances with nanobubbles, separates water vapor and gaseous substances with pin separators and slit separators, condenses and treats water vapor through perforated equalization plates and condensation plates, and generates eddy currents as a flow path plate. The remaining gaseous substances are cleaned by mixing the bubble cleaning water with the internal gas, and the internal gas that has undergone cleaning is finally cooled down through the heat exchanger and returned back to the inside of the composting unit to lower the concentration of the internal gas in the composting unit. It relates to an internal gas treatment system in a decomposition chamber that allows to work inside a little more smoothly.

As environmental issues have recently emerged as the top issue in the 21st century, internal gases such as odorous gases, fine dust, and nitrogen oxides emitted from composted organic fertilizer manufacturing facilities are being pointed out as one of the causes of environmental pollution. There are 1,470 such decomposed organic fertilizer manufacturing facilities nationwide. These facilities are largely divided into fully open composting facilities, partially open composting facilities, and fully enclosed composting facilities. In the case of the double open type and the partially open type, the internal gas from the compost flows into the air as it is and causes environmental pollution, and NH ₃ in the internal gas reacts with ozone in the air to become fine dust and causes air pollution. In addition, when it rains and the compost is washed away by rainwater, it causes various problems such as contamination of the surrounding land or groundwater.

In order to solve this problem, the government has strengthened legal regulations on ripened organic fertilizer manufacturing facilities. Government regulations require that open and partially open composting facilities be converted to closed structures.

The problem is that when an open composting facility is changed to a closed type, the gas concentration, temperature, moisture, and heat inside the composting building increase. In particular, the concentration of toxic gases such as ammonia inside increases several times to several tens of times, and in fact, when the open type is converted to the closed type, the ammonia concentration of 150 ppm or less rises 10 times to 1500 ppm. This is the concentration that will cause the death of a person inside in 30 minutes. In other words, when sealed, the safety of workers who have to work for a long time inside the facility is threatened.

Therefore, there is a need to create an environment in which workers can work inside even after sealing the cooking compartment.

Conventionally, there are three representative methods of purifying gas discharged from industrial sites: running water, pressurized water, and filling tower.

The flow-through method is a method of cleaning the processing gas by filling the dust collection chamber with a certain amount of cleaning water and then passing the processing gas through it at high speed to form water droplets and a water film.

The pressurized water method is a method of cleaning the process gas with very small water droplets by spraying water under pressure.

The packed tower type is similar to the pressurized water type, but in order to increase the contact area between water and the processing gas, various fillers including a pall ring are filled in the middle of the tower, and most washing towers use such a packed tower type.

Among them, the third packing tower type is the most commonly used in the industry, and the facility using this is called a scrubber.

A scrubbing tower is a device that collects dust, gas, liquid particles, etc. using a liquid, and is generally used for processing gas generated during chemical treatment. The washing tower is a device that removes a large amount of chemicals, moisture (steam), and gases having characteristics such as high temperature, but may also be used to remove various odorous gases.

This washing tower has a simple structure and can handle high-temperature combustible and explosive gases, and has advantages such as treatment of droplet-type gas, improvement of collection efficiency, neutralization of corrosive gas and dust, simultaneous gas absorption and dust collection in a single device there is

However, this conventional method has a problem in that there is a limit to a huge amount of water vapor and temperature reduction included in the internal gas of the steaming building, and the washing liquid is easily contaminated and the amount of waste water is increased. In addition, it is an air pollution prevention technology that purifies polluted gas and discharges it into the atmosphere, but there is a limit to improving the environment inside the floating building, which deteriorates due to sealing. In other words, there is a need for a technology for purifying the internal gas of the aging chamber to simultaneously solve the increased internal gas concentration, temperature, moisture, and heat during sealing.

Meanwhile, Korean Patent Registration No. 10-2426866 relates to an odor treatment system of a composting facility and an odor treatment method using the same. It is possible to increase the fermentation efficiency of compost by supplying air with elevated temperature to the tank, post-cooking fermentation tank, packing room, and mechanical stirring-type fermentation tank, and by allowing the discharge process of condensation water generated inside the heat exchanger to be performed, mechanical stirring It relates to an odor treatment system of a composting facility that can efficiently remove odors generated in the composting process by removing odors and dust from air exhausted from a food fermentation tank, and an odor treatment method using the same. The typical configuration is a composting facility including a pretreatment facility consisting of a mixing tank, a post-maturation fermentation tank, a packaging room, and a mechanical agitation fermentation tank, wherein the mixing tank, post-maturation fermentation tank, and packaging room are connected to the heat exchanger and the first air supply line is configured to receive external air, and the mechanical agitation type fermentation tank is connected to the mixing tank, post-ripening fermentation tank, and packing room by a second air supply line to receive air from inside the mixing tank, post-ripening fermentation tank, and packing room, The mechanical agitation fermentation tank is configured to discharge internal air through an exhaust line positioned to indirectly intersect the first air supply line from the inside of the heat exchanger, and the first air supply line and the exhaust line are inside the heat exchanger. It is characterized in that it is installed and configured to cross adjacent positions so that mutual heat exchange is possible.

However, the patent describes that the internal air is condensed through heat exchange between the low-temperature external air and the internal high-temperature air, and the external air is heated and re-supplied to the mixing tank and fermentation tank. Therefore, the amount of external air supplied for heat exchange is inevitably limited, and there is a limit to lowering the condensation efficiency. In addition, it is described that odor and dust can be simultaneously removed by condensing through heat exchange, but a mechanism for this is not proposed and a purification treatment method for the removed condensate is not presented. In addition, in the summer, when the internal temperature of the fermenter rises to 55 degrees or more and the external air is heated and then supplied in a state where long-term internal work is impossible, the internal air temperature rises further, causing great trouble to workers or machinery.

As environmental issues have recently emerged as the top issue in the 21st century, internal gases such as odorous gases, fine dust, and nitrogen oxides emitted from composted organic fertilizer manufacturing facilities are being pointed out as one of the causes of environmental pollution. There are 1,470 such decomposed organic fertilizer manufacturing facilities nationwide. These facilities are largely divided into fully open composting facilities, partially open composting facilities, and fully enclosed composting facilities. In the case of the double open type and the partially open type, the internal gas from the composting process leaks into the air as it is, causing environmental pollution. control is needed

More specifically, as shown in FIG. 3A, the conical portion 1200 has a conical shape with a lower end cut off, and the tubular conical portion outlet 1220 may penetrate from the upper end to the middle.

The inlet pipe 1100 is connected to the upper end of the conical part 1200, so that the internal gas introduced from the inlet pipe 1100 flows into the upper end of the conical part 1200 and the circumferential surface of the conical part 1200. It rotates along and creates centrifugal force. In this way, centrifugal force is formed in the internal gas, and particulate matter and moisture present in the internal gas are pushed out of the internal gas by the centrifugal force and collide with the conical wall 1210, passing through the opening at the bottom of the conical portion 1200 to the water tank 5000. ) can be released.

Meanwhile, FIG. 3B schematically shows another embodiment of the present invention.

The conical portion 1200 according to another embodiment of the present invention does not form one conical portion 1200, but forms a plurality of the conical walls 1210 and the conical outlet 1220 to form a plurality of conical portions. In the case of forming the mini conical portion 1200, more efficient particulate matter may be detached than the single large conical portion 1200. This is called a multi-cone part.

More specifically, the internal gas introduced into the inlet pipe is equally distributed to the plurality of conical parts 1200, and each centrifugal force is formed in each of the conical parts 1200, and at this time, the single conical part A relatively small cone may be formed compared to (1200).

In this way, by forming the conical portion 1200 in plural, when a cone smaller than that of the single conical portion 1200 is formed, the coarse particles are relatively smaller than the coarse particles that fall out of the single conical portion 1200. Since it can also be eliminated, the treatment efficiency can be further increased.

The heat exchange of the part 1260 increases the efficiency of moisture condensation of the high-temperature internal gas, and the size of moisture particles can be increased due to the collision between the rotating internal gas and the conical protrusion 1230 .

The conical portion 1200 of FIG. 3A has a structure that narrows towards the lower end focusing on the separation of simple particulate matter, but since particulate matter and moisture coexist in the internal gas, they must be removed at the same time. To this end, the centrifugal force is increased by increasing the diameter toward the lower end, and at the same time, the internal gas collides with the conical protrusion 1230 to coarsen the moisture particles to remove moisture.

On the other hand, a conical outlet skirt 1200 in the form of a cone without an end is installed at the lower end of the conical outlet 1220 so that the conical protrusion 1230 collides with the rotating internal gas and particulate matter is re-scattered again. The inflow into the internal gas and the contaminant gas cleaning unit 1300 can be prevented.

In addition, by installing a cool jacket unit for bringing cold air or washing water into contact with the surface of the conical unit, the temperature of the internal gas passing through the conical unit can be lowered, thereby increasing the condensation efficiency so that moisture contained in the internal gas can be better condensed.
