Environment-friendly bitumen dissolving and conveying system and method in carbon product industry

Abstract

The invention discloses an environment-friendly bitumen dissolving and conveying system and method in the carbon product industry. A heat exchange pipe in a storage tank of the system is connected with a heat exchanger and a hot oil furnace through control valves respectively. The upper end of the storage tank is provided with a solid bitumen inlet, a liquid bitumen inlet and a smoke exhaust port. The liquid bitumen inlet is communicated with a liquid storage stank through a pipeline and a control valve. The smoke exhaust port is connected with a purifier through a fan. The lower end of the storage tank is communicated with an oil conveying tank through a pipeline and a control valve. The oil conveying tank and the liquid storage tank are connected with a compressed air pipe through control valves respectively. A discharge pipe is arranged on the oil conveying pipe. An internal liquid sensor and a temperature sensor are arranged in the storage tank. Raw materials are under completely sealed conditions since entering stations, automatic production is realized, the working environment is good, bitumen-induced occupational injuries and pollution of bitumen to the air are avoided, energy conservation and environmental protection are achieved, and damage to pumps and valves due to bitumen solidification cannot be caused.

Description

Technical field: [0001] The invention relates to asphalt melting equipment, in particular to an environment-friendly asphalt melting and conveying system and method in the carbon product industry. Background technique: [0002] In the production process of carbon products, coal tar pitch is widely used as a binder and impregnating agent raw material, and this process, whether using solid coal tar pitch or liquid coal tar pitch, must have storage, heating, heat preservation, cooling and high temperature (125- -250°C), because coal tar pitch is a toxic and harmful substance whether it is solid or liquid, once it comes into contact with or inhales human smoke, it will cause harm to the body. However, the traditional process cannot be guaranteed to be carried out in a completely closed state during its production process, and it is impossible to completely avoid causing harm to the staff. Most of the conveying equipment uses liquid asphalt pumps. Increased resistance can lead t...

[0002] In the production process of carbon products, coal tar pitch is widely used as a binder and impregnating agent raw material, and this process, whether using solid coal tar pitch or liquid coal tar pitch, must have storage, heating, heat preservation, cooling and high temperature (125- -250℃), because coal tar pitch is a toxic and harmful substance whether it is solid or liquid, once it touches or inhales human smoke, it will cause harm to the body.

However, the traditional process cannot be guaranteed to be carried out in a completely closed state during its production process, and it is impossible to completely avoid causing harm to the staff. Most of the conveying equipment uses liquid asphalt pumps. Damage or motor burnout occurs due to increased resistance
