Description

A waste reclamation gas batch processing device

The present invention relates to a waste landfill gas batch processing device, and more particularly, to allow each device for filtering impurities in the waste landfill gas to be filtered through an integrated landfill gas processing device.

In general, wastes that cannot be incinerated among industrial wastes are landfilled, and organic wastes of landfilled wastes generate landfill gas during biological decomposition.

Methane is the main component of such landfill gas and contains carbon dioxide, nitrogen, hydrogen, oxygen and other trace components.

Among these, methane gas has a greenhouse effect about 21 times higher than carbon dioxide, which is a factor of environmental pollution and climate change. Therefore, the necessity of a facility for capturing and treating methane gas has emerged, and many devices are utilized.

Representative methods of treating methane gas are the direct incineration of methane gas after it is collected in landfills, used as fuel for landfill gas power generation or heating and cooling facilities, and as an auxiliary fuel for incineration plants.

In particular, the concentration of methane in landfill gas is generally 50% or more, which is sufficient to be used as alternative energy, but the system technology of the collecting process is weak.

A representative apparatus and method for landfill gas treatment is disclosed in Korean Patent Laid-Open Publication No. 2003-0047296, but in such a method, a pretreatment process for removing water from landfill gas has a very complicated problem and maintains a constant pressure. Methane gas can not be discharged, there is a problem that the stable treatment of methane gas is difficult. In addition, a small amount of oxygen may be included during the intake and treatment of landfill gas, and methane gas may be ignited if appropriate temperature and pressure conditions are included along with a small amount of oxygen.

In addition, the application No. 10-2009-0038754 is a landfill gas treatment apparatus for organic waste, the vertical pipe for sucking the landfill gas of the landfill; A gas filter unit for filtering foreign matter contained in the landfill gas sucked through the vertical pipe by a filter and collecting and separating water contained in the landfill gas downward; A water-sealed vacuum pump for discharging the landfill gas sucked together with the water, which is a working fluid, after rotational compression; A gas-liquid separation unit for collecting water introduced together with the landfill gas from the water-sealed vacuum pump downward, and discharging the landfill gas upward; A cooling unit connected to the gas-liquid separation unit and the water sealing vacuum pump to circulate the internal water, and indirectly cooling the water supplied to the water sealing vacuum pump by the cooling water supplied from the outside; A gas storage unit in which the landfill gas from which moisture is first removed from the gas-liquid separation unit is introduced and stored, and collects and discharges the water in the landfill gas downward again; A landfill gas burner in which the landfill gas supplied from the gas storage unit is burned; A pilot burner which is ignited by supply of fuel gas which is separately provided for ignition of the landfill gas burner; The landfill gas burner and the pilot burner are provided and include a combustion chamber in which combustion of the landfill gas occurs. When the discharge pressure of the water seal vacuum pump is higher than a set pressure, the discharged water and landfill gas are discharged. There is a bypass pipe that bypasses the suction side of the sealed vacuum pump.

Since the landfill vacuum pump is introduced with the landfill gas together with water, it is possible to prevent ignition due to friction during the compression process of the landfill gas, and a cooling unit used for gas cooling and gas transfer is unnecessary.

In addition, in the conventional landfill gas treatment facility as described above, a compressor is used to continuously inhale the landfill gas at a constant pressure and compress and discharge the sucked landfill gas. Such a compressor is composed of a rotary or reciprocating type. Friction may cause heat or sparks. In this case there is a safety problem, such as the possibility of causing an explosion due to the ignition of methane.

As described above, as a whole, the configuration of the processing apparatus is complicated, so there are many difficulties in the facility, and there is a problem in that it is inexpensive in terms of facility cost and maintenance.

The present invention is to solve the problems of the prior art as described above,

The filter (f) is mainly intended to filter impurities in the landfill gas (g) sucked through the suction pipe 600, the material is a polypropylene (PP: Polypropylene) nonwoven fabric (f1) and polypropylene (PP: Polypropylene) ball ( ball (f2), and the filter (f) should be inclined (10 ~ 20 °).

The filter should be constructed such that a polypropylene (PP: Polypropylene) nonwoven fabric (f1) and a plurality of Polypropylene (PP) balls (f2) are stacked.

In addition, when the separation plate 110 is configured to be inclined (10 to 20 °) as in the configuration of the filter (f) should be installed.

This allows the landfill gas (g) to filter through the inclined filter (f) when the landfill gas (g) is sucked into the lower portion partitioned by the filter (f). ) Landfill gas (g) that penetrates the ball (f2) contacts the laminated polypropylene (PP) nonwoven fabric (f1), whereby the landfill gas (g) is a polypropylene (PP) ball. (ball) (f2) separates the moisture and passes through the laminated polypropylene (PP: Polypropylene) nonwoven fabric (f1). In addition, the moisture produced by contacting the polypropylene (PP) ball (f2) is to be accumulated in the lower end of the inclined separator plate 110 of the lower portion. Here, the moisture accumulated in the lower end of the separator 110 can be discharged to the outside through the discharge valve (v) configured on the outside.

In addition, the pressure may be generated due to the landfill gas (g) sucked to configure the pressure control valve 120 on the upper portion of the gas filter unit 100 to adjust the pressure inside the gas filter unit 100.

The landfill gas g, first filtered by the gas filter unit 100, is transferred to a transfer fan 200 provided at an outer side of the landfill gas processing apparatus.

The transfer fan 200 consumes a lot of power and supply water in a conventional water-sealed vacuum pump, requires a drainage treatment facility, and takes into account that the performance of the vacuum pump is affected by water temperature and quantity. And it can be selectively used among the check valve, one end connected to the transfer fan 200 should be provided with an outlet 210.

The outlet 210 is configured to be disposed in the water (w) in the water layer 310 of the gas-liquid separator 300 so that the landfill gas (g) is discharged in the water (w) in the water layer (310). This is to remove impurities while the landfill gas (g) through the discharge port 210 is reacted with the water (w) when discharged to rise above the water surface.

In the gas-liquid separator 300 divided into a landfill gas g, which is sucked through the transfer tank 200, is divided into a water layer 310 having a predetermined water level at a lower portion thereof and a dispersion layer 320 having a seeding tower 322 at an upper portion thereof. Secondary filtering of the landfill gas (g) is possible.
