The reaction kettle comprises a reaction kettle and a rotary shaft which is arranged in the middle part of the reaction kettle, wherein a blade is arranged on the rotary shaft and a control cabinet is arranged in the upper part of the reaction kettle; a motor is arranged at the upper end of the reaction kettle, the rotary shaft is connected with the motor through a coupler, the blade is a spiral blade and the motor is connected with the control cabinet through a line; a material storage cabin is arranged on one side of the reaction kettle, a charging pump is arranged on one side of the material storage cabin, the charging pump is connected with the reaction kettle through a one-way valve, and the charging pump is connected with the control cabinet through a line; a pressure-relieving tank is arranged on one side of the reaction kettle, an electromagnetic valve is arranged between the pressure-relieving tank and the reaction kettle, and the electromagnetic valve is connected with the control cabinet through a line. By detecting the pressure and temperature value of the reaction kettle and realizing real-time pressure relief, the safe operation of the reaction kettle is ensured.
Description
technical field [0001] The invention relates to a reactor with a safety pressure relief structure and a pressure relief control method thereof. Background technique [0002] In the process of chemical production, during the chemical reaction of reagents in the reactor, the pressure in the reactor will change. When the pressure change reaches the upper limit that the reactor can withstand, the chemical reagent may be denatured due to the pressure change. In order to avoid affecting the operation of the existing reactor due to failure to release the pressure in time, a pressure relief valve is usually set for the pressure relief operation, and the safety performance is low. Contents of the invention [0003] The object of the present invention is to provide a reactor with a safety pressure relief structure and its pressure relief control method, which can improve the problems existing in the prior art, and realize real-time pressure relief by detecting the pressure and temp...
