Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically relating to a gas-solid separation device for a phenolic resin high-pressure reaction vessel. Background Technology

[0002] Phenolic resin is a polymer compound formed by the condensation polymerization of phenol and formaldehyde under the action of a catalyst. It is divided into thermosetting and thermoplastic types. It has the characteristics of good heat resistance, excellent electrical insulation, high chemical stability and good mechanical properties. It is widely used in adhesives, casting, daily necessities and other fields, and is a widely used polymer material.

[0003] The synthesis of phenolic resin is usually carried out in a reactor, where the pressure is typically at atmospheric or negative pressure. Small quantities of the product require high-temperature and high-pressure curing. After curing in the reactor, the material needs to be discharged under positive pressure. Currently, the discharge method is direct discharge, but this is extremely dangerous. High-temperature solvent gases are released around the reactor's feed port at the moment of material discharge, which can easily cause burns to operators. The high-temperature solvent gases with strong irritating odors can also cause dizziness and vomiting in operators. The resulting waste gas will cause air pollution. To solve these problems, it is necessary to either purchase a more suitable reactor or add a new discharge device, while also modifying the structure of the existing reactor. All of these solutions would impose a significant economic burden on the company.

[0004] To address the aforementioned issues, a gas-solid separation device for a high-pressure phenolic resin reactor is proposed. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, this utility model provides a gas-solid separation device for a high-pressure reactor for phenolic resin, which completely improves the problem that operators are prone to burns, dizziness and vomiting, while greatly reducing air pollution.

[0006] The technical solution adopted in this utility model is as follows: a gas-solid separation device for a high-pressure phenolic resin reactor, including a reactor, a gas-solid outlet at the bottom of the reactor is sealed to a gas-solid separation component via a flange, the gas-solid separation component includes a solid material tank, the bottom of the solid material tank is connected to a support device, an inlet is provided on the upper side of the solid material tank near the reactor, the height of the inlet is lower than the height of the gas-solid outlet, an inlet valve is provided at the inlet, and the inlet is sealed to the gas-solid outlet via an inlet pipe; a solid discharge component is provided at the bottom of the solid material tank, an exhaust port is provided at the top of the solid material tank, the exhaust port is sealed to an exhaust pipe via a flange, a gas collection tank is provided on one side of the solid material tank, an air inlet is provided at the top of the gas collection tank, the gas collection tank is filled with coolant, an exhaust pipe is sealed to the exhaust port and extends below the coolant level in the gas collection tank, and a pressure relief component is provided at the top of the gas collection tank.

[0007] The solids bin is a rectangular prism made of stainless steel.

[0008] The support device includes brackets at both ends of the solid material box, a support plate fixed in the middle of the brackets, the solid material box being positioned above the support plate, and a through hole being formed in the middle of the support plate.

[0009] The solid discharge assembly is located at the lower part of the side wall of the solid material box or at the middle of the bottom of the solid material box, and includes a solid discharge port with a solid discharge valve.

[0010] The exhaust pipe is a plastic hose with a steel wire coil inside.

[0011] The pressure relief assembly includes a pressure relief port, and a pressure relief valve is installed on the pressure relief port.

[0012] The exhaust pipe extends to the bottom of the gas collection box, which is filled with coolant, accounting for 70-50% of its volume.

[0013] The reactor includes a reactor body, a feeding port on one side of the top of the reactor body, a through hole at the center of the top of the reactor body, a magnetic stirrer fixedly mounted above the reactor body and passing through the through hole at the center of the top of the reactor body to connect with a stirring shaft, a stirring blade mounted on the stirring shaft, an explosion-proof motor connected to the top of the magnetic stirrer, the reactor body fixedly mounted on a support frame, the explosion-proof motor fixedly connected to the support frame and held in place by the support frame, a gas-solid discharge port at the bottom of the reactor body, and a gas-solid discharge valve mounted on the gas-solid discharge port.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention, after actual testing, completely improves the problems of operators being easily burned, experiencing dizziness and vomiting, while significantly reducing air pollution. By setting up a gas-solid separation component, the phenolic resin can be directly discharged into the gas-solid separation component after the reaction is completed. The solid remains in the solid material tank, and the gas enters the coolant in the gas collection tank through the top of the solid material tank. The coolant accelerates the cooling of the high-temperature gas and dissolves harmful substances in the high-temperature gas into the coolant, reducing air pollution caused by exhaust gas. It effectively prevents operators from being burned by high-temperature exhaust gas and avoids dizziness and vomiting caused by high-temperature solvent gases with strong irritating odors. This invention has low cost and does not change the original reactor structure, so enterprises do not need to purchase a new reactor, which greatly saves production costs and has a high cost-performance ratio.
