Precautions For Use Of Heat Exchanger
- Oct 11, 2017 -


First, the Heat Exchanger controller should be flat on the console, the surrounding medium should not contain conductive dust and corrosive gases, suitable operating environment temperature of 10-40 ℃, relative humidity should be less than 85%.
Second, the Heat Exchanger should be placed indoors. When equipped with multiple Heat Exchanger, should be placed separately.
Third, the positive and negative nut joints, only quasi-rotating positive and negative nuts, two circular sealing surface shall not be relative to the rotation, all nuts and connectors are installed, should be coated with oil. Each operating room should have direct access to the outdoor or channel outlet, should ensure that the equipment address ventilation is outstanding.
Fourth, the hand plate on the Heat Exchanger on the rotary body, check the work is not flexible.
5, in the installation of Heat Exchanger cover, should avoid the reactor body reaction between the sealing cover surface collision with each other. The reactor cover carefully placed in the corresponding position of the reactor body, tighten the main nut, you must press the diagonal, symmetrically repeated gradually tightened. Force to be uniform, do not allow the reactor cover to the side of the skew, in order to achieve a good sealing effect.
Six, needle valve line line seal, just quietly rolling its valve needle, press it the sealing surface, you can achieve a good sealing effect.
With the progress of technology, now the probability of Heat Exchanger blasting has been greatly reduced, but this does not mean that the decomposition of the blasting does not occur, in fact, if there is a serious production or improper use of the operation or will bring decomposition blasting Of the danger, such as too much catalyst or feed too fast lead to instantaneous temperature rise too fast and so will cause the Heat Exchanger decomposition blasting. Therefore, in the safe production of Heat Exchanger, we must strictly abide by the "Heat Exchanger use precautions, this article will introduce the reasons for the Heat Exchanger blasting and some use of the precautions.
Causes and Treatment of Heat Exchanger
1, the reactor into the mechanical impurities, resulting in local friction heat caused by the decomposition of the reactor blasting. Treatment: pay attention to maintenance do not fall into the mechanical impurities.
2, the bearing assembly wear and tear, resulting in overheating after the temperature rise caused by decomposition of the reactor blasting. Treatment: strict inspection of spare parts quality, improve maintenance quality.
3, stirrer paddle and kettle wall friction caused by local overheating caused by Heat Exchanger decomposition blasting. Treatment: improve the quality of maintenance and spare parts quality.
4, the catalyst system instrumentation or catalyst pump operation failure caused by the decomposition of the reactor blasting. Treatment: maintenance, commissioning instruments, to achieve accurate and sensitive.
5, too much catalyst or feed too fast, instantaneous temperature rise too fast lead to decomposition blasting. Treatment: strict control of the amount of catalyst, feeding should be uniform.
Heat Exchanger structure and performance: equipment mainly by the tank, jacket, mixing system composed of three parts. In the case of
1, the Heat Exchanger material: contact with the material are used 304 or 316L and other high-quality stainless steel, in line with GMP standards. In the case of
2, the Heat Exchanger accessories: mixing the form of multi-purpose frame mixing to ensure that the material in a short time evenly reconcile; at the same time according to the need to use box, anchor, pulp and so on. Sealed with a mechanical seal, you can ensure the pressure inside the tank and to prevent leakage of material in the tank and cause unnecessary pollution; interface with ISO standard fast clamp type, convenient health; sterile respirator, CIP cleaning nozzle, mirror , Flange, health and other people quickly open. In the case of
3, the Heat Exchanger surface treatment: the inner surface of the mirror polished to ensure that no health dead angle, fully enclosed design to ensure that the material is always in a sterile state, the outer surface optional sandblasting, matte, cold rolling primary color treatment. In the case of
4, heating and cooling: heating methods optional steam, electric heating, heat transfer oil to meet the acid, alkali, high temperature, abrasion resistance, corrosion and other different working environment needs of the process.
