Description

Technical Field

[0001] The invention relates to the technical field of condensate collection and treatment, and in particular to a device and method for collecting condensate from a biogas torch. Background Art

[0002] Biogas torch is a byproduct of anaerobic fermentation of biogas, which is a normal production product of modern sewage treatment plants, alcohol plants, and farms. Its main components are 50-65% methane and 30-50% carbon dioxide, as well as hundreds of other components such as water vapor, sulfide, and nitrogen. Among them, methane is one of the main greenhouse effect pollutants.

[0003] Biogas not only pollutes the environment but also poses serious safety hazards, so anaerobic biogas needs to be centrally processed. For factories or places with small gas production, biogas torches are generally set up to burn the centrally collected biogas. Biogas torches have the functions of improving site safety, increasing social recognition, reducing odor pollution, and reducing the greenhouse effect.

[0004] The existing biogas torches inhale air mixed with biogas through the air inlet for combustion. Active air inhalation can make the biogas burn fully, but because the biogas will carry a large amount of sewage and solid impurities during the production process in the biogas tank, if it is not pre-treated, it will affect the normal operation of production when entering the subsequent torch, and even cause mechanical failure due to excessive load during the treatment process; in addition, the condensed water generated during the combustion process contains a variety of harmful substances. If this condensed water is not treated and discharged directly, it will cause pollution to the soil and groundwater.

[0044] Embodiment 2:

[0045] See also Figure 1-Figure 5 , and on the basis of Example 1, it is further obtained that: Another technical problem to be solved by the present invention is to provide a method for collecting condensed water from a biogas torch, which specifically includes the following steps:

[0046] Step 1: First, ventilate the entire equipment and preheat the biogas torch to ensure smooth gas flow in the system;

[0047] Step 2, start the condensate collection device, and pass the biogas containing sewage and solid particulate matter into the gas transmission pipe 15, along the inlet valve pipe 26, and enter the condenser 28 through the inlet port A and the outlet port A on the four-way valve structure 25. The biogas is heated by the electric heating wire 29 in the condenser 28, so that the generated water vapor condenses on the inner wall of the condenser 28, and the formed condensate flows along the inner wall through the 180° fan-shaped filter plate 223 into the 180° fan-shaped collecting funnel 224.

The circulation fan 222 at the top of the guide circulation plate 22 can automatically adjust the rotation speed according to the gas humidity. If the humidity is too high, the circulation fan 222 will accelerate the rotation to increase the biogas circulation speed until the biogas is dry, and then the top circulation fan 222 is closed, and the outlet valve fan inside the outlet valve pipe 27 is opened to discharge the biogas and transport it to the torch;

[0049] Step 4: The condensed water coming out of the water collection hole 225 at the bottom of the 180° fan-shaped collecting funnel 224 flows along the collecting bucket 226 and the filter cartridge 228, and the condensed water generated during the combustion process falls into the filter cartridge 228 through the collecting pipe 110 and is collected together, and finally discharged to the outside of the collecting cartridge 21 through the drain pipe 229.

The top of the inner cylinder of the filter cartridge (228) is an inverted cone-shaped opening, and a detachable filter screen is arranged therein. The bottom of the inner cylinder of the filter cartridge (228) is an inverted pointed cone-shaped opening, and the bottom is connected to a sewage pipe (229); a temperature sensor is arranged on the side wall of the outer cylinder of the filter cartridge (228).

9. The biogas torch condensate collection device according to claim 1, characterized in that: One side of the torch body (11) is also connected to a collecting pipe (110), and the other end of the collecting pipe (110) passes through the collecting tube (21) and extends into the circulating purification chamber, and continues to pass through the guide circulation plate (22), and finally extends to the interior of the 180° fan-shaped collecting funnel (224).

10. A method for collecting condensed water from a biogas torch according to claims 1-9, characterized in that: The method specifically comprises the following steps: Step 1: First, ventilate the entire equipment and preheat the biogas torch to ensure smooth gas flow in the system; Step 2: Start the condensate collection device, and let the biogas containing sewage and solid particulate matter enter the gas transmission pipe (15), along the inlet valve pipe (26), and enter the condenser (28) through the inlet port A and the outlet port A on the four-way valve structure (25). The biogas is heated by the electric heating wire (29) in the condenser (28), so that the generated water vapor condenses on the inner wall of the condenser (28), and the formed condensate flows along the inner wall through the 180° fan-shaped filter screen (223) into the 180° fan-shaped filter screen (223). The fan-shaped collecting funnel (224) has a plurality of air holes on its outer wall, and the air holes are covered with a liquid-isolating air-permeable membrane, which has the function of extracting air and further guides the flow of biogas. The inner wall of the collecting funnel is provided with a moisture-absorbing sponge for absorbing moisture in the condensate production chamber, thereby ensuring the internal humidity balance of the system and ensuring that the biogas and the condensate carried by it can be separated after entering the collecting funnel, thereby effectively reducing the moisture content in the gas and improving the dryness of the biogas. Step 3, the biogas coming out of the air vent will be detected by the gas flow meter (23), and the circulation fan (222) at the bottom of the guide circulation plate (22) can automatically adjust the rotation speed according to the gas flow, so that the biogas can quickly enter the circulation purification chamber, and after being purified by the 180° fan-shaped filter screen plate (223) on the right, the humidity is detected by the humidity detector (24). The circulation fan (222) at the top of the guide circulation plate (22) can automatically adjust the rotation speed according to the gas humidity. If the humidity is too high, the circulation fan (222) will accelerate the rotation to increase the biogas circulation speed until the biogas is dry, then the top circulation fan (222) is closed, and the outlet valve fan inside the outlet valve pipe (27) is opened to discharge the biogas and transport it to the torch; Step 4, the condensed water coming out of the water collection hole (225) at the bottom of the 180° fan-shaped collecting funnel (224) flows along the collecting bucket (226) and the filter cartridge (228), and the condensed water generated during the combustion process falls into the filter cartridge (228) through the collecting pipe (110) and is collected together, and finally discharged to the outside of the collecting cartridge (21) through the drain pipe (229).
