Glass reactor in the process of work need to pay attention to those problems | summarize chapter

With the development of science and technology, the development of glass reactor industry is also gradually accelerated, the type and function of the increasing, widely used. The double-layer glass reaction kettle produced by our factory is in the closed glass reaction kettle under the condition of setting constant temperature, and it can be stirred and reacted under the condition of atmospheric pressure or negative pressure according to the requirements of use, and it can do the reflux and distillation of the reaction solution, which is currently the ideal equipment for modern refinement, biopharmaceuticals and the synthesis of new materials. With the development of technology, as well as biopharmaceutical and other industries to expand the demand, the development of double-layer glass reactor is also accelerating, and product types and functions continue to increase, the more widely used. Glass reactor is widely used in petroleum, chemical, pesticide, pharmaceutical, food and other industries, used to complete the sulfurization, nitrification, hydrogenation, hydrocarbonization, polymerization, condensation and other processes of the pressure vessel.

Reasonable installation and correct operation of the equipment is a prerequisite to ensure the stable operation of the double-layer glass reactor. The industry said that in the process of double-layer glass reactor work, in fact, some places are very easy to be ignored by users. In this regard, the industry has summarized according to experience, and the author has made a brief collation. Among them, the double-layer glass reactor can be used according to the requirements of the stirring reaction under atmospheric pressure or negative pressure conditions, and can carry out the reaction solution reflux and distillation, with high precision temperature measurement, small error, high efficiency. The industry said, double-layer glass reactor in the process of work, some places are easy to be ignored by the operator, need to pay great attention. Specifically, there are the following aspects：

1、The choice of medium, including insulation medium and temperature control medium. Among them, due to the small thickness of the interlayer in the middle of the double-layer glass reactor, the insulation performance is poor. Therefore, in the use of high temperature and low temperature process, it is necessary to use thermal insulation materials to insulate and protect the kettle body. For the kettle body of the reactor as well as the liquid-conducting tubes need to be wrapped with thermal insulation materials, and pay attention to the thickness of the insulation layer to ensure that there is a good thermal insulation effect.

In the choice of temperature control medium, the user can choose different properties of the temperature control medium according to the required reaction temperature, as the reaction of the heat propagation medium. When using low or high temperatures, pay attention to the selection of the appropriate medium.

"The key lies in the viscosity. The viscosity is too large for the medium circulation pump may not be able to carry, and the circulation effect is not good enough to achieve a satisfactory temperature control effect. And rashly replace the high-power circulation pump, easy to damage the double glass reactor liner, making the reactor rupture." The industry said that, in general, manufacturers will be based on their own Products, supporting the corresponding heating medium for users to choose.

2、storage location. Double glass reactor as a reaction amplification test device, the volume is usually 50 - 150L, the volume can be customized for specific cases, therefore, the scale of the test should not be underestimated. As the kettle body is made of glass, stainless steel for the bracket and casters, so the storage location needs to be carefully selected.

According to the reaction of some users, the casters of double-layer glass reactor can be fixed with foot buckles, but the stability is not strong. Therefore, the storage of attention to choose a flat place, try to put flat, and keep the center of mechanical stirring and reaction kettle consistent, otherwise easy to shake unstable, safety accidents. In addition, the general floor ventilated kitchen can not be placed, but must be placed in a place with good ventilation position.

3、The double-layer glass reactor is an independent reaction shelf, and the reserved refilling port is small, so the refilling process is more difficult.The industry suggests that for solid reagents, it is recommended to formulate a solution to be added into the kettle, while liquid reagents can be pumped into the kettle through the supporting water pump or oil pump.

It is worth noting that, through the constant pressure dripping funnel or common dripping funnel will be added to the reaction kettle reaction material, need to support the corresponding mobile ladder, so that the staff to join the test material.In addition, in the process of feeding, double-layer glass reactor should not be too large a one-time feeding amount, according to the temperature, reflux and pressure of the reaction, after evaluation to join the appropriate amount of material.

4、Pay attention to the heat preservation. It is understood that due to the small thickness of the interlayer in the middle of the double glass reactor, the heat preservation performance is poor. In the process of using high temperature and low temperature, users need to use thermal insulation materials to insulate and protect the kettle body.

At the same time, the user needs to wrap the kettle body of the reactor as well as the tubes of the liquid conductivity with thermal insulation materials, paying attention to the thickness of the thermal insulation layer to ensure that there is a better thermal insulation effect.

5、Temperature control medium selection. Generally speaking, the user will choose different properties of the temperature control medium according to the desired reaction temperature, as the reaction of the heat propagation medium. Low temperature choose ice ethanol bath, room temperature choose water bath, high temperature choose oil bath.

The industry suggests that when using low or high temperatures, attention should be paid to choosing the right medium, the key is viscosity. "Viscosity is too large medium, the circulation pump may not be able to carry, the media circulation effect is not good, can not achieve the desired temperature control effect. Rashly replace the high-power circulating pump, pressed into the medium pressure is too high, easy to damage the double glass reactor liner, the reactor rupture."It is understood that usually manufacturers will be based on their own products, supporting the corresponding heating medium for selection.

6、The storage location needs to be reasonable. As a reaction amplification test device, the volume of the double glass reactor is usually 50 - 150L, and the volume can be customized for specific cases, so the scale of the test should not be underestimated. Since the kettle body is made of glass, stainless steel is the support and the frame is on casters, the storage location needs to be carefully selected.

In terms of storage conditions, although the casters can be fixed with foot buckles, but the stability is not strong. Therefore, the user in the storage process, pay attention to choose a flat place to put, and keep the center of mechanical stirring and reactor consistent, otherwise easy to shake unstable, safety accidents. In addition, it must be placed in a place with good ventilation.

7、Filling Precautions. As the double-layer glass reactor is an independent reaction shelf, and the reserved charging port is small, so the charging process is difficult.In this regard, the industry suggests that solid reagents can be formulated into solution and added into the kettle, and liquid reagents can be pumped into the kettle through the supporting pump or oil pump. In particular, the reaction material will be added into the kettle through constant pressure drip funnel or common drip funnel, which needs to be equipped with corresponding mobile ladder so that the staff can add the test material.

In addition, in addition to the above precautions, the user in the ordinary use of the process, but also need to regularly on the double-layer glass reactor maintenance, to ensure that the life of the equipment, reduce enterprise costs. Double-layer glass reactor one-time feeding volume should not be too large, the user needs to be based on the reaction of the temperature, reflux and pressure, to assess, add the appropriate amount of material, generally should not exceed 2/3 of the kettle body.
