Abstract

Technical Field
[0001] The utility model relates to the technical field of hydrazinolysis reaction pressure control, in particular to a hydrazinolysis reaction pressure control device. Background Art
[0002] Hydrazinolysis refers to the process in which organic compounds containing various functional groups generate hydrazine derivatives under the action of hydrazine, including hydrazinolysis of halogens and esters. Hydrazine, also known as hydrazine, has an alkalinity of only one-fifteenth of ammonia and can react with acids, such as N2H4+H+→[N2H5]+K=8.5x10-7. It can be seen that hydrazine hydrochloride (N2H4·HCl) is a strong acid and weak base salt, which is highly hydrolyzed in aqueous solution and is strongly acidic. In addition, hydrazine can also react with oxygen to generate nitrogen and water.
[0003] The hydrazine hydrolysis reaction in the prior art requires the control of the required temperature and pressure, but the temperature can be controlled by stopping heating. However, the pressure will cause gas pressure to be generated during the reaction, affecting the reaction effect. The pressure needs to be controlled at a constant pressure. The traditional method is inconvenient to operate and cannot be operated conveniently and at low cost. Utility Model Content
[0004] The utility model aims to provide a hydrazine hydrolysis reaction pressure control device. When the internal pressure of the reactor is greater than the supporting pressure of the supporting spring, the sealing ball plug elastically returns to the pressure, the sealing ball plug rises and separates from the pressure relief port, so that the internal pressure of the reactor can be discharged, thereby achieving the pressure relief effect.
[0005] To achieve the above-mentioned purpose, a hydrazine hydrolysis reaction pressure control device is provided, comprising: a reactor and a pressure tank, wherein a vacuum pump is fixedly connected to one side of the top of the reactor, an input end of the vacuum pump is fixedly connected to a vacuum tube, one end of the vacuum tube is fixedly connected to the pressure tank, an output end of the vacuum pump runs through the interior of the reactor, a pressure relief valve is fixedly connected to one side of the top of the reactor, a support spring is fixedly connected to the top of the pressure relief valve, a sealing ball plug is fixedly connected to the bottom end of the support spring, an arc ring is fixedly connected to the bottom end of the pressure relief valve, and the arc ring and the sealing ball plug are sealed.
[0006] According to the hydrazine hydrolysis reaction pressure control device, a plurality of pressure relief ports are penetrated through the middle outer surface of the pressure relief valve.
[0007] According to the hydrazine hydrolysis reaction pressure control device, a driving motor is fixedly connected to the middle of the top of the reactor, a stirring rod is fixedly connected to the driving end of the driving motor, and the stirring rod and the inner bottom of the reactor are rotatably matched.
[0008] According to the hydrazine hydrolysis reaction pressure control device, a pressure sensor is fixedly connected to one side of the inner top of the reactor.
[0009] According to the hydrazine hydrolysis reaction pressure control device, a control panel is fixedly connected to the middle of the front side of the reactor.
[0010] According to the hydrazine hydrolysis reaction pressure control device, a plurality of heating wires are fixedly connected to the inner wall of the reactor.
[0011] According to the hydrazine hydrolysis reaction pressure control device, a feed hopper is fixedly connected to the other side of the top of the reactor.
[0012] The above scheme has the following beneficial effects:
[0013] The utility model is provided with a vacuum pump, a pressure tank, a supporting spring and a sealing ball plug. The internal pressure of the pressure tank is vacuum-inputted into the interior of a reactor through the vacuum pump. Subsequently, pressure is generated in a reaction process. At this time, when the internal pressure of the reactor is greater than the supporting pressure of the supporting spring, the sealing ball plug elastically returns to pressure. The sealing ball plug rises and separates from the pressure relief port, so that the internal pressure of the reactor can be discharged, thereby achieving a pressure relief effect, facilitating control of the internal pressure of the reactor and maintaining a desired constant pressure. At the same time, different elastic coefficients can be used to control different pressures by replacing the supporting spring.
