Description

Technical Field

[0001] This utility model relates to the field of biogas flares, specifically a premixed biogas flare. Background Technology

[0002] Biogas is one of the commonly used fuels and is a byproduct of normal production in modern sewage treatment plants, alcohol plants, and farms. Biogas not only pollutes the environment but also poses serious safety hazards. Therefore, it is necessary to centrally treat anaerobic biogas. For factories or places with small biogas production, biogas flares are generally set up to burn the centrally collected biogas. Biogas flares have the functions of improving site safety, increasing social acceptance, reducing odor pollution, and reducing the greenhouse effect.

[0003] Traditional biogas flares often suffer from uneven mixing of biogas and combustion air due to the lack of premixing. This results in incomplete combustion, black smoke, substandard emissions, slow combustion, low processing efficiency, unstable flames, and easy flameout. To address these issues, those skilled in the art have developed a premixed biogas flare to resolve the problems described in the background section. Utility Model Content

[0004] The purpose of this utility model is to provide a premixed biogas flare in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a premixed biogas flare, comprising a chassis and a hollow connecting cylinder fixedly installed on the outer top surface of the chassis. An annular cylinder is fixedly installed on the outer top surface of the hollow connecting cylinder, and a windproof cylinder is fixedly installed on the outer top surface of the annular cylinder. A vertical gas supply pipe is provided inside the hollow connecting cylinder. One end of the vertical gas supply pipe passes through and extends to the inner bottom surface of the annular cylinder, and the other end of the vertical gas supply pipe extends to the outside of the hollow connecting cylinder and communicates with an air inlet pipe provided on the outer peripheral side wall of the right end of the hollow connecting cylinder. A blower is provided outside the left end of the hollow connecting cylinder, and the air outlet of the blower is connected to the annular cylinder through a pipe. An automatic igniter is fixedly installed inside the windproof cylinder. A premixing component is provided inside the annular cylinder for premixing the biogas transported by the vertical gas supply pipe and the combustion air transported by the pipe.

[0006] As a further technical solution of this utility model, the premixing component includes a rotating shaft rotatably mounted on the inner sidewalls of both sides of the annular cylinder, a connecting sleeve fixedly sleeved on the outer peripheral surface of the rotating shaft, and connecting pieces arranged in a circular array fixedly mounted on the outer peripheral surface of the connecting sleeve.

[0007] As a further technical solution of this utility model, configuration strips are fixedly installed on the three opposite outer surfaces of the connected pieces, and an exhaust pipe that communicates with the windshield tube is connected through the center of the outer top surface of the annular cylinder.

[0008] As a further technical solution of this utility model, a flame detector is fixedly installed on the inner peripheral side wall of the wind shield and above the automatic igniter, and a control box is fixedly installed on the outer peripheral side wall of the hollow connecting cylinder and above the gas supply pipe.

[0009] As a further technical solution of this utility model, a rain cover is fixedly installed on the outer top surface of the windproof tube by pillars distributed in a circular array.

[0010] As a further technical solution of this utility model, the end of the air intake pipe away from the hollow connecting cylinder is connected to a connecting pipe, and a flame arrester, a pressure gauge, a pressure switch and a control valve are fixedly installed on the end of the connecting pipe away from the hollow connecting cylinder in sequence.

[0011] As a further technical solution of this utility model, a flow valve is fixedly installed on the pipeline.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a vertical gas delivery pipe and conduit to transport biogas and combustion air into an annular cylinder. This propels a connecting plate, which, under the influence of counterweights, rotates around a rotating axis, ensuring uniform mixing of the biogas and combustion air and preventing incomplete combustion and low processing efficiency. Furthermore, the inclusion of a flame arrester, pressure gauge, pressure switch, and control valve allows for monitoring of the biogas pressure within the pipe and prevention of flame propagation. The control box also enables timely processing of adverse signals, allowing for fully automatic intelligent control of the biogas flare. Finally, a rain cover provides wind and rain protection, extending the flare's lifespan. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a premixed biogas flare technical solution: including a chassis 1 and a hollow connecting cylinder 101 fixedly installed on the outer top surface of the chassis 1. An annular cylinder 102 is fixedly installed on the outer top surface of the hollow connecting cylinder 101, and a windproof cylinder 103 is fixedly installed on the outer top surface of the annular cylinder 102. A vertical gas supply pipe 104 is provided inside the hollow connecting cylinder 101. One end of the vertical gas supply pipe 104 passes through and extends to the inner bottom surface of the annular cylinder 102, and the other end of the vertical gas supply pipe 104 extends to the outside of the hollow connecting cylinder 101 and communicates with the air inlet pipe 105 provided on the outer peripheral side wall of the right end of the hollow connecting cylinder 101. A blower is provided outside the left end of the hollow connecting cylinder 101. The air outlet of the blower is connected to the annular cylinder 102 through a pipe 106. An automatic igniter 107 is fixedly installed inside the windproof cylinder 103.

[0020] The annular cylinder 102 is equipped with a premixing component 2 for premixing the biogas transported by the vertical gas pipe 104 and the combustion air transported by the pipe 106. The premixing component 2 includes a rotating shaft 201 rotatably mounted on the inner sidewalls of both sides of the annular cylinder 102. A connecting sleeve 202 is fixedly sleeved on the outer peripheral surface of the rotating shaft 201. Connecting plates 203 arranged in a circular array are fixedly installed on the outer peripheral surface of the connecting sleeve 202. Counterweight bars 204 are fixedly installed on the opposite outer surfaces of the three connecting plates 203. An exhaust pipe 205 that communicates with the windproof cylinder 103 is connected through the center of the outer top surface of the annular cylinder 102. A rain cover 401 is fixedly installed on the outer top surface of the windproof cylinder 103 through the support columns 4 arranged in a circular array. A flow valve 6 is fixedly installed on the pipe 106.

[0021] Biogas is transported through the intake pipe 105 along the vertical gas delivery pipe 104 into the annular cylinder 102. At the same time, the blower is started to transport flame-retardant air along the pipe 106 into the annular cylinder 102. At this time, the biogas and combustion air push the connecting plate 203, which, under the action of the counterweight 204, rotates around the rotating shaft 201 to evenly mix the biogas and combustion air, thereby preventing incomplete combustion and low processing efficiency. The mixed gas is then transported to the windproof duct 103 through the exhaust pipe 205, and then automatically ignited by the automatic igniter 107 for combustion. During the combustion process, the rain cover 401 can prevent wind and rain, prevent the flame from going out, and affect the combustion effect.

[0022] A flame detector 3 is fixedly installed on the inner circumferential side wall of the windproof duct 103, above the automatic igniter 107. Meanwhile, a control box 301 is fixedly installed on the outer circumferential side wall of the hollow connecting tube 101, above the gas supply pipe. The flame detector 3 allows observation of the flame's combustion status to ensure equipment safety, while the control box 301 enables fully automatic intelligent control, ensuring the personal safety of personnel.

[0023] It should be explained that a flame detector 3 is a sensor device used to detect and monitor the presence of flames. It is widely used in industrial burners, boilers, furnaces, and various combustion equipment to ensure the safety and efficiency of the combustion process. A flame detector 3 typically consists of a probe section and a housing section. The probe section usually comprises a lens, optical fiber, and photosensitive element, while the housing section includes electronic circuitry, an amplifier board, and a single-chip microcomputer, among other components.

[0024] There are many models of flame detectors. Below are some common flame detector models and their characteristics:

[0025] Honeywell: Honeywell UV-5000: An ultraviolet flame detector designed specifically for detecting flames containing hydrocarbons such as methane.

[0026] ABB: ABB FFS100 Methane: A model specifically designed for biogas and methane flame detection, adaptable to the characteristics of biogas combustion.

[0027] Siemens: Siemens SITRANS FLUSCOM FM100: This flame detector is suitable for detecting flames from a variety of fuels, including biogas.

[0028] Emerson: Emerson Flame Detector 4150N: Capable of detecting flames from various fuels, including biogas.

[0029] Baker Instruments FL4000H: This is a high-sensitivity flame detector suitable for detecting methane and other hydrocarbon flames.

[0030] Fisher: Fisher 4600CH4: A flame detector designed specifically for methane (the main component of biogas).

[0031] A connecting pipe 5 is connected to the end of the air inlet pipe 105 away from the hollow connecting cylinder 101. A flame arrester 501, a pressure gauge 502, a pressure switch 503, and a control valve 504 are sequentially fixedly installed on the end of the connecting pipe 5 away from the hollow connecting cylinder 101. Through the functions of the flame arrester 501, pressure gauge 502, pressure switch 503, and control valve 504, the gas pressure inside the connecting pipe 5 can be detected, and the spread of flame from the pipe can be prevented, thus providing a certain degree of protection for the biogas flare and extending its service life.

[0032] The working principle of this utility model is as follows: When in use, the device is first installed in the working area through the threaded hole on the chassis 1. Then, the control box 301 controls and opens the control valve 504 on the connecting pipe 5 to transport biogas along the air inlet pipe 105 and the vertical gas delivery pipe 104 into the annular cylinder 102. Immediately afterwards, the flame-retardant air is controlled and started to be transported synchronously into the annular cylinder 102 along the pipe 106.

[0033] Simultaneously, the biogas and combustion air push the connecting plate 203 to make it rotate around the rotating shaft 201 under the action of the counterweight 204, so that the biogas and combustion air are evenly mixed, and then the mixed gas is transported to the windproof duct 103 along the exhaust pipe 205.

[0034] At the same time, the automatic igniter 107 performs automatic ignition to initiate combustion, and the flame detector 3 can observe the combustion process during the combustion process.

[0035] Finally, with the assistance of the rain cover 401, it can protect against wind and rain, and prevent the flame from going out.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
