Description

Technical Field

[0001] The invention relates to the technical field of special chemical raw material transportation, and in particular to a conveying mechanism for transporting propylene oxide. Background Art

[0002] Propylene oxide is an organic compound. It is a colorless, volatile liquid at room temperature with an ether-like odor. It is slightly soluble in water and can be miscible with organic solvents such as ethanol and ether. Since propylene oxide is flammable, explosive and toxic, it is necessary to use a dedicated propylene oxide transport tank for transportation and storage. The tank is usually made of pressure-resistant and corrosion-resistant materials. Before replenishing propylene oxide in the propylene oxide transport tank, it is necessary to use nitrogen to replace the remaining gas. Using nitrogen to replace the residual air or other gases in the tank can reduce the oxygen content and avoid the risk of combustion or explosion during the propylene oxide replenishment process. Then use a solvent to dissolve the remaining propylene oxide. A small amount of incomplete propylene oxide may remain in the transport tank. Directly flushing the discharged propylene oxide with water may cause it to accumulate in local areas and increase the risk of explosion. First, use an appropriate organic solvent (such as toluene, ethanol, etc.) to dissolve the residual propylene oxide in the tank to fully dilute it and reduce the danger. Finally, use clean water to rinse the propylene oxide transport tank. There may still be trace amounts of propylene oxide remaining after the solvent is dissolved. Finally, flush the tank with a large amount of clean water to completely remove the chemical residues in the tank, prevent contamination of the newly loaded propylene oxide, and ensure the safety and cleanliness of the transport tank. The three steps of nitrogen replacement-solvent dissolution-flushing with large amounts of clean water can effectively reduce safety hazards and ensure the stability and purity of the tank when it is refilled with propylene oxide.

[0003] However, in the prior art, when the conveying mechanism for propylene oxide transportation is replenished with propylene oxide, the three steps of nitrogen replacement - solvent dissolution - flushing with a large amount of water require high professional operation requirements of the workers. The workers are prone to make mistakes and cause the operation steps to be in the wrong order. If the operation sequence of the propylene oxide transport tank is wrong before replenishment, it may cause serious danger. For example, if the propylene oxide storage tank is directly flushed with a large amount of water before solvent dissolution, propylene oxide is likely to form a stable emulsion after contact with water, so that the residue adheres to the tank wall, reducing the subsequent cleaning effect and causing residual pollution. Water cannot effectively dilute or dissolve the propylene oxide residue in the tank, but may cause it to accumulate in a local area to form a high-concentration gas phase, which may cause combustion and explosion when encountering a fire source or static electricity. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, when a conveying mechanism for propylene oxide transportation is replenished with propylene oxide, the three steps of nitrogen replacement - solvent dissolution - flushing with a large amount of clean water have high requirements on the professional operation of workers, and workers are prone to make mistakes in operation, resulting in a wrong order of operation steps.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. The main structure of the present invention includes a water tank, a nitrogen tank, and a solvent tank. The water tank, the nitrogen tank, and the solvent tank are all arranged on the top of the bearing platform, and a sequential control component is arranged on one side of the top of the bearing platform. The sequential control component can be realized based on the gravity of the solvent tank. The sequential control component can control the solvent tank to completely fill the main tank with solvent. The main tank can only import cleaning water, and forcibly control the order of dissolving first and then cleaning the main tank, effectively avoiding the safety hazards and incomplete cleaning problems caused by misoperation. The design ensures that the solvent must completely fill the main tank before the cleaning water is allowed to enter, avoiding the risk of emulsification of propylene oxide, difficulty in removal, or excessive local gas concentration causing explosion due to direct water flushing.

[0025] 2. The present invention is additionally provided with a forced liquid replenishment component on the top of the receiving platform. The forced liquid replenishment component ensures that sufficient cleaning resources are always available during the transportation process to prevent insufficient cleaning resources due to negligence of workers, thereby affecting the complete cleaning process of the main storage tank; ensures that solvent dissolution and water rinsing can be carried out according to the standard process after each transportation to prevent the accumulation of residual propylene oxide; reduces safety hazards and prevents the risk of propylene oxide volatilization, explosion or pollution caused by incomplete cleaning; improves operating efficiency, avoids the need for additional replenishment due to insufficient cleaning resources, reduces waiting time, and improves equipment turnover; reduces human operating errors, ensures that workers cannot skip key steps, and ensures the integrity of the cleaning program.

[0026] 3. The present invention is provided with a switching component at the end of the sewage outlet pipe of the main storage tank, and a processing box is provided at the end of the sewage outlet pipe. An activated carbon plate is provided inside the processing box. The switching component is linked with a back-blowing valve which controls whether nitrogen is blown into the main storage tank by the nitrogen tank. When nitrogen is blown into the main storage tank, the switching component can automatically guide the propylene oxide discharged from the sewage outlet pipe to the multiple activated carbon plates, thereby reducing environmental pollution and damage to the human body. When the cleaning solvent or cleaning water is discharged from the sewage outlet pipe, the cleaning solvent or cleaning water is directly discharged from the reserved pipeline on the side of the processing box instead of being guided to the activated carbon plate, thereby realizing the classified treatment of propylene oxide waste gas and cleaning liquid, reducing pollution. The propylene oxide waste gas is adsorbed by the activated carbon plate, reducing environmental emissions and improving safety; protecting the health of workers and avoiding direct emissions of harmful gases; improving processing efficiency, the cleaning solvent and water bypass the activated carbon plate and are directly discharged, thereby preventing the activated carbon from being saturated and failing; extending the service life of the activated carbon, reducing maintenance costs, and making the cleaning and waste gas treatment more efficient, environmentally friendly, and economical.
