The second communication module 19b is connected to the control server 51. The control server 51 controls on/off of the pressure pump 18 through the second communication module 19b. The operation of the pressure pump 18 is controlled remotely through the control server 51. The gas pumped by the pressure pump 18 is delivered to the receiving pipe 21 through the gas supply pipe 22.

FIG. 2 is a perspective view showing the combustion unit 30 of FIG. 1, and FIG. 3 is a cutaway perspective view showing a part of the combustion unit shown in FIG. 2 when viewed from different angles. 4 is a plan view of the combustion unit shown in FIG. 2.

As shown, also, as briefly mentioned above, the combustion unit 30 includes a container 31, a moisture eliminator 32 arranged in series on the roof of the container 31, a gas filter 33, and a desulfurization device. (34), gas pressurizer (35), injection pipe (40) for guiding the gas pressurized by the gas pressurizer (35), flow meter (36) for sensing the flow rate of gas passing through the injection pipe (40), injection pipe It includes a combustion device 38 for burning the gas received through the (40).

In particular, the combustion unit 30 is installed on the upper portion of the base plate (41). The base plate 41 supports the container 31 and the combustion device 38 horizontally, and may be made of, for example, a steel plate having a predetermined thickness. Since the probability that the ground of the waste landfill Z is weak is high, the container 31 or the combustion device 38 may be inclined when the base plate 41 is not applied.

In addition, the support plate 43 is located under the container 31 and the combustion device 38. The supporting plate 43 is made of a steel plate as supporting the container 31 or the combustion device 38. In some cases, the base plate 41 can be fixed to the base plate 43 by bolting or welding.

The container 31 provides an inner space 31a in which a worker can reside. The gas analyzer 37 and the control server 51 are disposed in the inner space 31a. The gas analyzer 37 analyzes the components of the gas supplied to the combustion device 38. The information analyzed by the gas analyzer 37 is stored in the control server 51. The gas analysis data and the gas flow rate information identified by the flowmeter 36 are stored in the control server 51 in units of 10 seconds.

The moisture eliminator 32 passes the gas introduced through the receiving pipe 21 and removes moisture inside the gas. The moisture removal method of the gas follows the general moisture removal method.

The gas filter 33 serves to filter out foreign substances such as dust and sand mixed in the gas dried by the moisture eliminator 32. To this end, a filter plate (not shown) of various structures is built in the gas filter 33. Of course, it is possible to replace the filter plate mounted inside the gas filter 33.

The gas filtered by the gas filter 33 passes through the desulfurization device 34. The desulfurization device 34 removes the sulfur component in the gas. By removing the sulfur component, air pollution during combustion of the gas by the combustion device 38 can be prevented.

The components of the gas that have passed through the desulfurization device 34 are continuously analyzed by the gas analyzer 37. For gas analysis, a sensor (not shown) that detects a gas component is disposed downstream of the desulfurization device 34. As a result of gas analysis, if the sulfur content is higher than the reference value, the combustion facility is temporarily stopped, and the cause is identified and necessary measures are taken.

In addition, the analysis data of the gas analyzed by the gas analyzer 37 is stored in the control server 51 at 10 second intervals. The data stored in the control server 51 may be transmitted to an external supervisor, for example, the local department's environmental department manager through a separate communication network.

The gas pressurizer 35 serves to transport the desulfurized gas to the combustion device 38. The gas moved by the gas presser 35 passes through the injection pipe 40 and moves to the combustion device 38.

A flow meter 36 is mounted on the injection pipe 40. The flow meter 36 measures the flow rate of the gas passing to the combustion device 38 and delivers it to the control server 51. It is also possible to check the amount of carbon dioxide reduction while measuring the flow rate.

The combustion device 38 is spaced apart from the container 31 and takes the gas that has passed through the injection pipe 40 to combust and takes the form of a chimney. The combustion of the gas takes place at the lower end of the combustion device 38. The combustion device 38 is supported through a plurality of fixing wires 38b and does not collapse.

A flame detector 39 is installed on the side of the combustion device 38. The flame detector 39 detects a flame through a monitoring window (not shown) formed on the side of the combustion device 38, and the UV wavelength and infrared wavelength generated from the flame, as well as optical flickering of the flame, etc. Characteristic analysis. The flame detector 39 is also connected to the control server 51 and transmits detection information to the control server 51.

In addition, a plurality of temperature sensors 38a are arranged on the outer wall of the combustion device 38. The temperature sensor 38a detects the combustion temperature of the gas, that is, detects whether the temperature exceeds a set temperature. The measurement information of the temperature sensor 38a is also transmitted to the control server 51. When the combustion temperature is higher than 1700°C, for example, the flow rate of the gas supplied to the combustion device 38 is reduced to prevent overheating.

5 is a view for explaining an implementation example of a mobile methane gas combustion facility 10 according to an embodiment of the present invention.

As shown, a plurality of vertical collection pipes 12 and transfer collection pipes 14 are buried in the gas discharge area of the landfill, and each transfer collection pipe 14 is connected to the gas chamber 16 described above. have. In addition, a pressure feeding pump 18 is connected to the downstream side of the gas chamber 16, and the pressure feeding pump 18 extends toward the combustion unit 30 and is connected to one receiving pipe 21. The gas supply pipe 22 is one in which multiple pieces are connected in parallel to one receiving pipe 21.

In particular, between each gas supply pipe 22 and the receiving pipe 21, a flexible pipe 23, a solenoid valve 24 and a valve controller 25 are provided. The flexible pipe 23 allows the direction of the gas supply pipe 22 to be adjusted.

In the waste landfill (Z), since the vertical collection pipe 12 and the gas chamber 16 should be positioned at a point where the gas is relatively discharged, when the gas discharge point is changed, the gas chamber 16 must be moved and arranged. . The flexible pipe 23 is applied in consideration of the position change of the gas chamber 16. For example, when the gas chamber 16 needs to be moved in the direction of the arrow a, the direction of the gas supply pipe 22 can be easily changed without removing the gas supply pipe 22 from the receiving pipe 21. It is possible.

The solenoid valve 24 is a valve that is opened and closed by the valve controller 25. The valve controller 25 receives the operation signal of the control server 51 through the receiver 25a to open and close the solenoid valve 24. For example, if the concentration in any gas chamber 16 does not rise satisfactorily for a set time, the gas supply pipe 22 connected to the gas chamber 16 is blocked. The position of the gas chamber 16 is changed while the gas supply pipe 22 is blocked.

Reference numeral 21a is a main valve. The main valve 21a is a valve that opens and closes the receiving pipe 21. When the main valve 21a is blocked, the gas supply to the moisture eliminator 32 is blocked.

FIG. 6 is a side view showing a modification of the combustion unit 30 shown in FIG. 2.

As shown, a horizontal holding device 60 is installed between the base plate 41 and the base plate 43. The horizontal holding device 60 is, for example, to keep the container 31 and the combustion device 38 always horizontal even when the ground is recessed and the base plate 41 is inclined to one side.

The horizontal holding device 60 applies hydraulic pressure to the actuator 65 installed at the four corners of the square plate-shaped support plate 43, the support portion 63 located at the lower end of the actuator 65, and the actuator 65. It has a hydraulic source 48 to be applied, and a level system 47 that senses the level of the base plate 43.

Level 47 is fixed to the upper surface of the base plate 43 and detects the horizontal state of the base plate 43. Level 47, when the support plate 43 is tilted to one side can generate an alarm and notifies that the control server 51 also tilts.

The hydraulic source 48 includes a normal hydraulic oil tank and a hydraulic pump, and applies hydraulic pressure to the actuator 65 under the control of the control server 51. One actuator 65 is independently driven by one hydraulic source 48.

The cylinder 65a of the actuator 65 is fixed to the bottom surface of the base plate 43, and the piston rod 65b extends vertically. The piston rod 65b linearly moves in the vertical direction by the hydraulic pressure provided from the hydraulic source 48.

Base 63 is fixed to the lower end of the piston rod (65b) is provided in the vertical lower portion of the upper ball holder (63a), the upper ball holder (63a) having a receiving groove (63c) opened to the bottom and open to the top The ball receiving groove (63c) is formed between the lower ball holder (63b), the upper ball holder (63a) and the lower ball holder (63b) is sandwiched between the lower receiving groove and the upper receiving groove is made of a ball (63d) spaced apart . The ball 63d is capable of sliding in close contact with the inner circumferential surface of the ball receiving groove 63c.

Therefore, for example, even if the base plate 41 is inclined to one side, and the parallelism of the base plate 41 to the base plate 43 is broken, the force of the actuator 65 can be applied in the vertical direction. By controlling the four actuators 65 organically and independently, it is possible to always keep the base plate 43 horizontal.

As described above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made by those skilled in the art within the scope of the technical spirit of the present invention.
