Description

Technical Field

[0001] The utility model belongs to the technical field of crude benzene loading equipment, and in particular relates to a crude benzene automatic loading safety control system. Background Art

[0002] Crude benzene is one of the products of crude coal gas generated by coal pyrolysis. After deammoniation, coke oven gas contains benzene compounds, of which benzene is the main content, which is called crude benzene. Crude benzene is a light yellow transparent liquid, lighter than water and insoluble in water. During storage, unsaturated compounds, oxidation and polymerization form resin substances that dissolve in crude benzene, and the color becomes darker. Crude benzene is flammable, and its vapor can form an explosive mixture with air. It can cause combustion and explosion when exposed to open flames and high heat, and can react strongly with oxidants.

[0003] If the flow rate is too fast during the transportation process, static electricity is easily generated and accumulated. Its vapor is heavier than air and can spread to a considerable distance at a lower level. It will ignite when it encounters an open flame. Therefore, the safety control of the crude benzene loading process is very important. If it is not operated properly, it is very easy to cause serious accidents such as fire and explosion. In the face of the increasingly severe safety situation, it is very necessary to control the safe loading process of crude benzene during the loading process. Therefore, a crude benzene automatic loading safety control system is proposed. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] Embodiment 1, as Figure 1 As shown, a crude benzene automatic loading safety control system includes a crude benzene storage tank 1, which is used to store crude benzene and provide a source of crude benzene during the loading process. The crude benzene storage tank 1 is connected to a tank truck 3 through a delivery pipe 2, and the tank truck 3 is used to load crude benzene and transport the crude benzene from the crude benzene storage tank 1 to a destination. The delivery pipe 2 is used to transport the crude benzene from the storage tank to the tank truck 3. A delivery pump 4 is provided on the delivery pipe 2. The delivery pump 4 is responsible for pushing the crude benzene from the storage tank to the tank truck 3 by providing pressure during the loading process to achieve the delivery function.

[0019] An anti-overflow switch 5, a regulating valve 6 and a flow meter 7 are sequentially arranged on the delivery pipe 2. The anti-overflow switch 5 is arranged on the delivery pipe 2. Once the flow rate of crude benzene is too large or an abnormality occurs in the pipeline, the delivery can be cut off in time to avoid the overflow of crude benzene and the occurrence of safety accidents. The regulating valve 6 controls the loading process by adjusting the flow of crude benzene in the delivery pipe 2 to ensure the accuracy and stability of the loading amount. The flow meter 7 is used to measure the flow of crude benzene and monitor the loading situation in time.

[0020] An exhaust gas absorption tower 9 is arranged at the rear of the tank truck 3. The exhaust gas absorption tower 9 is used to absorb the crude benzene vapor diffused during the process, reduce the crude benzene vapor content, and ensure the safety of the environment and the workplace. The exhaust gas absorption tower 9 is provided with a hanger 10, and an absorption cover 11 is arranged at the bottom of the hanger 10. The absorption cover 11 is used to collect and absorb the crude benzene vapor, avoid the occurrence of vapor diffusion and backfire, and improve the safety of the loading process. The hanger 10 is installed on the exhaust gas absorption tower 9 to support and maintain the stability of the absorption cover 11.

[0021] The following is a detailed description of the design of the above key components:

[0022] The anti-overflow switch 5, regulating valve 6 and flowmeter 7 are electrically connected to the controller 8.

[0023] The hanger 10 is hollow inside and is provided with a pipe, which can draw crude benzene vapor from the tank truck 3 into the absorption tower, thereby improving the absorption effect and preventing exhaust gas from escaping and polluting the environment.

[0024] The absorption cover 11 is suspended above the tank truck 3 and can conveniently cover the space above the tank truck 3. The purpose of this design is to absorb and collect crude benzene vapor during the crude benzene loading process, prevent vapor diffusion and backfire, and improve the safety of the loading process.

[0025] The controller 8 has a control chip integrated inside. The controller 8 can realize functions such as data analysis, alarm, automatic adjustment, etc. through the processing of the control chip, realize automatic control of the loading process, improve safety and efficiency, and the integration of the control chip also makes the system have a higher level of intelligence.
