Description

TECHNICAL FIELD

[0002] In the production, storage and transportation links of gasoline, its acidity and alkalinity is easily disturbed by many factors. For example, the sulfur-containing compounds contained in gasoline and various additives and other ingredients can cause fluctuations in pH value. Once the pH value of gasoline deviates from the normal range, not only will it have a negative impact on the operating performance of the engine, reducing its power output and fuel economy, but it can also increase the emission of harmful substances in exhaust gas and exacerbate environmental pollution.

However, this method has exposed many problems in practical application. First, its operation process is relatively slow, making it difficult to meet the demand for rapid adjustment in industrial production. Second, it is difficult to achieve continuous and stable adjustment of pH value, and it is easy to appear over-adjustment or insufficient adjustment, resulting in pH value exceeding the predetermined range. Third, when dealing with liquids containing volatile weak acid ions or weak base ions, the effect of traditional pH adjustment device is often unsatisfactory, and it cannot achieve ideal adjustment accuracy and stability.

[0019] The utility model relates to a kind of injection device for adjusting gasoline PH value, mainly including the following main components:

[0020] Mounting rack 1: The mounting rack 1 is a steel structure frame, which is used to fix multiple carbon dioxide gas cylinders 4. The mounting rack 1 is provided with multiple mounting pipe clamps, each of which corresponds to a carbon dioxide gas cylinder and is used to fix the gas cylinder to ensure its stable installation. The bottom of the mounting pipe clamp is provided with a supporting plate to further support the gas cylinder and prevent it from shaking.

[0021] Carbon dioxide gas cylinder 4: Multiple carbon dioxide gas cylinders 4 are installed on the mounting rack 1, and each carbon dioxide gas cylinder 4 is connected to the gas collecting pipe 3 through a connecting pipe 2. The connecting pipe 2 is provided with a connecting valve for controlling the flow direction and flow rate of the carbon dioxide gas.

[0022] Gas collecting pipe: The gas collecting pipe 3 spirals in the heat exchanger 5, one end of which is connected to the connecting pipe of the carbon dioxide gas cylinder 4, and the other end is connected to the pressure reducing valve 6. This spiral design increases the contact area between the gas and the heat exchanger 5, so that the carbon dioxide gas can be fully preheated before entering the delivery pipe 8.

[0023] Pressure reducing valve 6: The pressure reducing valve 6 is installed on the delivery pipe 8 and is used to adjust the pressure of the carbon dioxide gas to ensure that the gas enters the subsequent system at an appropriate pressure.

[0027] Gas collecting pipe 3 and connecting pipe 2: The material of the gas collecting pipe 3 and the connecting pipe 2 is stainless steel, which has good corrosion resistance and mechanical strength and can adapt to complex industrial environments.

[0028] The operation method is as follows: hot water or hot steam enters the heating cavity of the heat exchanger through the inlet pipe, exchanges heat with the carbon dioxide gas in the gas collecting pipe, increases the temperature of the carbon dioxide gas, thereby improving its reaction activity; then, the preheated carbon dioxide gas enters the pressure reducing valve through the gas collecting pipe, and is subjected to pressure reduction treatment according to the set pressure value, to ensure that the gas enters the conveying pipe at a suitable pressure; then, the carbon dioxide gas after pressure reduction enters the conveying pipe, the flow meter monitors the gas flow in real time, the one-way valve prevents backflow of the gas, and by accurately controlling the flow of the carbon dioxide gas, the carbon dioxide gas is injected into gasoline to react with the alkaline components in the gasoline, thereby reducing the pH value of the gasoline; finally, the hot water or hot steam in the heat exchanger is discharged through the outlet pipe after completing heat exchange, and enters the next cycle or processing link.

[0029] The beneficial effects of the present application include that by accurately controlling the flow and pressure of the carbon dioxide gas, rapid, continuous and stable adjustment of the pH value of the gasoline can be realized, effectively solving the problems of slow operation and inaccurate adjustment of the traditional acid-base neutralization method; secondly, the design of the heat exchanger improves the preheating efficiency of the carbon dioxide gas and enhances its reaction effect with the gasoline, further improving the adjustment accuracy and stability; in addition, the structural design of the mounting frame, mounting pipe clamp and supporting plate ensures stable installation of the carbon dioxide cylinder and improves the overall stability of the device; at the same time, the use of the stainless steel gas collecting pipe and connecting pipe enhances the corrosion resistance and mechanical strength of the device and prolongs the service life; finally, the use of the cascade self-control regulating valve realizes automatic adjustment of the flow of the heat exchange medium, improves the automation degree and operation efficiency of the system, and provides reliable protection for accurate regulation of the pH value of the gasoline.
