Description

Technical Field

[0001] The utility model relates to the technical field of liquid phase combustion, in particular to a liquid phase combustion generator. Background Art

[0002] Liquid phase combustion is a method of generating heat energy by burning liquid fuel. It is usually used in thermal power generation, industrial heating and other fields. Liquid phase combustion has the advantages of high efficiency, stability and safety. It can provide continuous and adjustable heat output and is suitable for large-scale energy utilization and industrial production processes. At the same time, liquid phase combustion is one of the main technologies for thermal power generation, industrial heating and liquid fuel processing. Thermal power generation mainly converts chemical energy into thermal energy by burning fuel, and then uses thermal energy to drive steam turbines or gas turbines to generate electricity; industrial heating mainly provides high-temperature heat sources to promote chemical reactions or dry materials; liquid fuel processing mainly improves fuel quality and utilization through liquid phase combustion.

[0003] During use, most of the existing liquid phase combustion generators transport liquid fuel to the interior of the generator through a connecting pipe. After the liquid fuel is burned in the liquid phase, the waste liquid is discharged through the connecting pipe. However, the liquid fuel inside the liquid phase combustion generator is prone to incomplete combustion. Directly discharging the waste liquid can easily lead to a waste of liquid fuel, which not only increases economic costs but also causes a waste of resources. It is necessary to design a liquid phase combustion generator to solve the above-mentioned problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a liquid phase combustion generator.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A liquid phase combustion generator comprises a first connecting pipe, a second connecting pipe and a third connecting pipe, wherein a water-liquid separation device is arranged at one end of the first connecting pipe, the first connecting pipe is connected to the water-liquid separation device, a gas-liquid separation device is arranged at the other end of the first connecting pipe, an output end of the gas-liquid separation device is fixedly connected to one end of the second connecting pipe, the first connecting pipe and the second connecting pipe are both connected to the gas-liquid separation device, a liquid flow meter is arranged at the middle of the second connecting pipe, and the middle and the other end of the second connecting pipe are connected to the left and right sides of the third connecting pipe; the water-liquid separation device is used to separate the incompletely burned liquid fuel in the waste liquid of the liquid phase combustion generator from the water generated after combustion; the gas-liquid separation device is used to separate the incompletely burned liquid fuel in the waste liquid of the liquid phase combustion generator from the gas generated after combustion; the liquid flow meter is used to measure the amount of the incompletely burned liquid fuel;

[0007] Through the above technical scheme, after the waste liquid passes through the water-liquid separation device, the incompletely burned liquid fuel is separated from the water produced after combustion. The gas-liquid separation device separates the incompletely burned liquid fuel in the waste liquid of the liquid phase combustion generator from the gas produced after combustion. The liquid flow meter is then used to calculate the amount of incompletely burned liquid fuel passing through, thereby solving the problem of incomplete combustion of liquid fuel inside the liquid phase combustion generator. Directly discharging the waste liquid can easily lead to waste of liquid fuel, while reducing economic costs and increasing resource utilization.

[0008] Further, a first valve body is provided in the middle of the first connecting pipe, a second valve body is provided in the middle of the second connecting pipe and the position connected to the left side of the third connecting pipe, and a third valve body is provided in the position connected to the other end of the second connecting pipe and the right side of the third connecting pipe;

[0009] Through the above technical solution, the second valve body is opened, the third valve body is closed, and the incompletely burned liquid fuel is transported through the third connecting pipe. The second valve body is closed, the third valve body is opened, and the incompletely burned liquid fuel is calculated through the liquid flow meter. Since the flow velocity in the liquid flow meter is relatively slow, the control valve is added to calculate the flow rate at a fixed time, and the liquid fuel is transported through the third connecting pipe during the rest of the time to increase the flow velocity.

[0010] Furthermore, a first branch pipe is provided on the upper portion of the water-liquid separation device, and a second branch pipe is provided on the upper portion of the gas-liquid separation device;

[0011] Through the above technical solution, the water separated from the waste liquid is discharged through the first branch pipe, and the gas in the waste liquid is discharged through the second branch pipe.

[0012] Furthermore, a first shunt pipe is provided in the middle of the second connecting pipe, and a second shunt pipe is provided on the right side of the third connecting pipe;

[0013] Through the above technical solution, it is convenient to add the second valve body and the third valve body when the second connecting pipe and the third connecting pipe are connected to each other.

[0014] Furthermore, the first connecting pipe, the second connecting pipe and the third connecting pipe are connected to the water-liquid separation device, the gas-liquid separation device and the liquid flow meter by flanges;

[0015] The above technical solution facilitates installation and disassembly while increasing the convenience of replacing damaged pipelines.

[0016] Furthermore, the first connecting pipe, the second connecting pipe and the third connecting pipe are all made of stainless steel pipes with a diameter of 8 cm, and the wall thickness of the first connecting pipe, the second connecting pipe and the third connecting pipe is 2 mm;

[0017] Through the above technical solution, the flow rate is increased by increasing the pipe diameter, while the structural strength of the first connecting pipe, the second connecting pipe and the third connecting pipe is increased to avoid leakage caused by damage.

[0018] The utility model has the following beneficial effects:

[0019] First, the input end of the water-liquid separation device is connected to the output end of the liquid phase combustion generator. After the waste liquid passes through the water-liquid separation device, the incompletely burned liquid fuel is separated from the water generated after combustion, and the separated water is discharged through the first branch pipe. Then, the first valve body is opened, and the incompletely burned liquid fuel is input into the gas-liquid separation device through the first connecting pipe, and the incompletely burned liquid fuel in the waste liquid of the liquid phase combustion generator is separated from the gas generated after combustion. The separated gas is discharged through the second branch pipe. Next, the second valve body is opened, and the third valve body is closed. The incompletely burned liquid fuel flows through the second connecting pipe again. The liquid fuel is then transported to the third connecting pipe, and finally the second valve body is closed and the third valve body is opened to allow the incompletely burned liquid fuel to pass through the liquid flow meter, and the amount of incompletely burned liquid fuel passing through per minute is calculated, thereby calculating the total amount of incompletely burned liquid fuel. This facilitates the discharge of moisture and gas in the waste liquid after the liquid fuel is burned and used, so that the incompletely burned liquid fuel can be purified and used again, thereby solving the problem of incomplete combustion of liquid fuel inside the liquid phase combustion generator, thereby directly discharging the waste liquid and easily leading to waste of liquid fuel, while reducing economic costs and increasing resource utilization.
