Pressurizing desulfurizing apparatus and process

Abstract

The present invention relates to rubber industry technology, and is especially pressurized desulfurizing apparatus and process. The pressurized desulfurizing apparatus includes a tank with a medium heating layer, a material inlet and a material outlet, a heating furnace communicated to the heating layer, a desulfurizing kettle inside the tank and with sliding rails in the bottom to match the tank bottom, a door, a material inlet, a material outlet and an inside heat conducting pipe communicated with its inner cavity. The desulfurizing kettle is matched with automatically controlled electric heater and pressurizing unit to raise duslfurizing efficiency and decrease exhausted pollutant. The present invention has low apparatus cost and low power consumption.

Description

technical field [0001] The invention relates to desulfurization equipment in the field of rubber industry, in particular to a pressurized desulfurization device and process. Background technique [0002] The current desulfurization tank is equipped with an agitator in a tank with a heating layer. The agitator is connected by a motor and a reducer. The heating furnace usually uses a coal-fired furnace to heat the heating layer of the tank to improve the rubber in the tank. Temperature, and the upper and lower sides of the tank are separately provided with inlet and outlet ports. The process parameters of the desulfurization tank are: pressure 1.6MPa----2.0MPa temperature 180℃----220℃. The main problems of this type of desulfurization tank are as follows: first, motor stirring is required, which increases equipment cost and energy consumption, and at the same time, the shaft of the motor is difficult to seal, resulting in the leakage of harmful gas; second, affected by the te...

Problems solved by technology

The main problems of this type of desulfurization tank are as follows: first, it needs motor stirring, which increases equipment cost and energy consumption, and at the same time, it is difficult to seal the shaft of the motor, resulting in the leakage of harmful gas; second, affected by the temperature of the heating furnace, the tank It is difficult to increase the working temperature and pressure, which affects the efficiency and time of desulfurization; the third is that the harmful gas produced lacks filtration and purification devices, resulting in environmental pollution
