Shop operator safety regulations

Reactor before driving:
1, check the kettle, blender, rotating parts, auxiliary equipment, indicating instruments, safety valves, piping and valves are in line with safety requirements.
2, check the water, electricity, gas meet the safety requirements.
Reactor driving:
1, before feeding the reactor should open the mixer, no noise and normal, the material will be added to the reactor, the number of feeding may not exceed the requirements of the process.
2, open the steam valve, first open the valve, open the intake valve. Open the steam valve should be slow, so that the jacket preheating, step by step, the pressure inside the jacket is not allowed to exceed the specified value.
3, steam valve and cooling valve can not start at the same time, steam pipeline gas is not allowed to hammer and collision.
4, open the cooling medium (water, 7 degrees of water, salt water, Leng Yichun) valve, the first open circuit valve, the valve into the road. Cooling medium pressure shall not be less than 0.1 MPa, and shall not be higher than 0.2 mpa.
5, water ring vacuum pump, to open the pump water, when the pump stops, the first stop after pump water, and should be excluded in water pump.
6, screw dry vacuum in strict accordance with the operating rules.
7, at any time to check the operation of the reactor, abnormal parking should be found.
8, cleaning the reactor, or the use of alkaline brush reaction kettle, be careful not to damage the enamel.
After reactor shutdown:

Safety rules for post operation of incinerator

First, the principle of proficiency
Although the incinerator system adopts the automatic control mode of operation of furnace safety procedures burned, but not the operation of the whole system of laissez faire, only rely on equipment automatic control is not safe, but the efficiency is very low.
In order to operate safely and efficiently, it is necessary for every operator to grasp the structure and principle of the whole system on the basis of the understanding of the performance of each equipment and the operating rules.
Second, the starting principle
1, the first stage should be starting air and garbage, shutdown stop is superior, the back Shun stop principle, if subordinates did not start, and start the superior may cause congestion, overload fault; during shutdown, if not stop will have similar fault.
2, before the start of the general, alarm, monitoring device should be started, so that they are in a state of monitoring, power supply must be continuously to the instrument. In order to record the status parameters of the whole working process.
Third, before the start of preparation
1, confirm the boiler working state is normal.
2, confirm the waste heat boiler is in normal state (for reference of waste heat boiler operation standard).
3, check the oil and hydraulic oil, check the grate is no exception, and then start the hydraulic device, further confirm the current and voltage and driving state.
4, confirm the status of the air baffle under the grate, and then turn it off.
5, send the garbage into the grate, and will be filled with garbage hopper.
6, the fan baffle all closed, when the fan to achieve the rated speed, adjust the furnace pressure is -50Pa--30Pa.
Note: prior to the start of the fan to confirm the flow of cooling water. Furnace pressure is -80Pa, the highest -20Pa. When to open the furnace gear plate, the furnace pressure drop to -80Pa.
7, to confirm the fuel system, fuel pump (a pump) is working properly, start the blower, open the steam supply valve and confirm the steam pressure.
Fourth, start
1, after the ignition of fuel injector, confirm the flame stability, open the main valve oil, a fuel ignition device, so that it is in a low load combustion (injection amount, low oil), according to the situation after the ignition, waste incineration, adjusting the oil valve, when the temperature reaches 750 DEG C, stop feeding. Stop oil, first of all should be slowly reduced oil supply, and then observe the furnace mild waste combustion, and then stop the oil.
2, according to the principle of reverse start all the ash conveyor, keep the ash machine water level is normal, confirm no blocking.
3, pay attention to the waste heat boiler pressure and temperature will not rise too fast.
4, when the incinerator temperature rises to 400 degrees, adjust the air baffle under the grate incinerator, in order to ensure the required air, gas should control the rate of temperature rise, rise too fast on the furnace wall and the smoke exhaust channel detector on the negative.
5, when up to 600-750 DEG C burning garbage is stable, depending on the situation, the one nozzle switch to waste oil, can also ignite two nozzle, and can be put into use, waste water sludge nozzle.
6, everything is normal, into the normal operation, the operator should often patrol, adjust the working state of the equipment.
Fifth, stop furnace
1, the feeding hopper in garbage all input furnace cover, feeding hopper cover, when the garbage is not continuous combustion, stop supplying air to the grate, to prevent the resurgence, when no flame, slow speed and reduce the furnace grate gear plate for air volume, at the same time, should pay attention to reduce as much as possibleIn order to prevent positive pressure in the furnace. It is important to stop before the fan, should closely monitor changes in temperature.
2, cooling water should be continuous supply. Until the waste heat affected the equipment to fully cool. After shutdown, check and repair the breakdown of the equipment to start the operation.
Sixth, emergency treatment
1, blower and fan due to failure to stop running, the furnace is burning, will lead to a wind baffle machine, fully open, and should reduce the intensity of combustion flame, prevent channeling into other places, and is ready to resume operation after the operation. Stop for a long time, should be extinguished the fire (such as the fire extinguished naturally, while paying attention to the water level of boiler grate, temperature and exhaust temperature).
2, ash removal system in a certain level of failure, should first of all the ash removal machine. Its steps in accordance with the stop, to restore normal reverse.
3, if the cooling water and boiler feed water stop, should cease fire immediately, except in a short time to restore supply.
Maintenance items:
Weekly maintenance items
1, fan bearing grease, dust removal impeller.
2, if there is a loose screw lock.
3, check the emergency discharge switch.
4, check and remove dirt. The cyclone combustion, and clean.
5, add rolling bearings, air compressor oil.
6, clean and filter, filter, filter Y filter element.
7, remove coke ash, atomizer.
Two, monthly maintenance
1, cleaning burner nozzle and ignition electrode rod.
2, the replacement of rolling bearings, air compressor oil.
Three, the quarterly maintenance items
1, replace the fan, air compressor belt.
Four, annual maintenance
1, replace the rolling bearing.
2, replace the fan bearing.
3, repair off refractory mud.
4, replace the burner nozzle, ignition electrode rod.
