In the pharmaceutical and chemical
production, the automatic temperature control system of the reactor is widely
visible. In order to ensure the safe production of the enterprise, what should
users pay attention to when facing unexpected situations?

When the production temperature and
pressure of the water-cooled chiller of the automatic temperature control
system of the reaction kettle rise rapidly and cannot be controlled, close all
the material inlet valves quickly; stop stirring immediately; quickly close the
steam (or hot water) heating valve and turn on the cooling water (or chilled
water) ) Cooling valve; quickly open the vent valve; when there is no vent
valve and the temperature and pressure cannot be controlled, quickly open the
discharge valve at the bottom of the equipment to discard materials; when the
above treatment has no effect, and the discharge of the bottom discharge valve
cannot be completed in a short time, Quickly notify the staff to evacuate the
scene

When a large number of toxic and harmful
substances are found to be leaking, immediately notify the surrounding
personnel to evacuate the site quickly upwind; quickly wear a positive pressure
respirator to close (or tightly) the toxic and harmful leakage valve; when the
toxic and harmful substance valve cannot be closed, then promptly notify the
downwind direction (Or around) the unit and personnel are scattered or
preventive work, and the treatment agent is sprayed according to the material
characteristics for absorption, dilution and other treatments. Store the leaked
material and deal with it appropriately.

If a large amount of flammable and
explosive material leaks, wear a positive pressure respirator quickly to close
(or tightly) the flammable and explosive leakage valve; when the flammable and
explosive leakage valve cannot be closed, promptly notify the surroundings
(especially the downwind direction) Personnel stop the production and operation
of open flames and sparks, and quickly stop other production or operations in
the surrounding area. At the same time, if possible, move the flammable and
explosive leakage to a safe area for disposal. Do not rush to close the valve
when the gas leakage has been burned. Pay attention to prevent flashback and
the gas concentration to reach the explosion point and cause an explosion.

The water-cooled chiller of the automatic
temperature control system of the reaction kettle is a relatively common
equipment in the pharmaceutical and chemical industry, and it is also an
important part of safe production, so as to minimize the occurrence of
accidents.
