First, the working principle:
1, through the sodium hydroxide solution as an absorbent, absorb the leakage of chlorine gas, remove harmful gases.
The main features are: ① strong absorption capacity, large capacity, non-toxic and harmless generation of sodium chloride; ② absorbent is not easy to aging, corrosion is small, can be recycled.
2, reaction principle:
Sodium hydroxide solution as the absorbing liquid, chlorine and sodium hydroxide neutralization reaction occurs after the generation of sodium chloride, the chemical reaction formula is as follows: Cl2 + 2NaOH = NaClO + NaCl + H2O
Second, the structure and workflow:
1, the device can ensure that the chlorine leakage out of the absorption in a timely manner, and harmless treatment. The fan will be chlorine gas from the bottom to the top into the absorption tower, the pump extracts the absorption liquid from the top to the bottom of the spray, chlorine gas in the absorption tower filler contact reaction, after the end of the reaction, the tail gas back to the chlorine bottle room, after the reaction of the liquid back to the solution box, after regeneration is pumped to the absorption tower for the reaction, and constantly recycling.
2, the device can effectively control the leakage of chlorine in the chlorine bottles and chlorine leakage absorption safety device composed of closed internal system to deal with, not to the atmosphere to emit harmful exhaust, dealing with the leakage of chlorine accident more thoroughly.
Third, the operating steps:
1, automatic state:
① chlorine leakage, chlorine leakage alarm will trigger the chlorine leakage absorption device will be triggered by the self-starting; ② usually must be played to the control gear? Automatic? When the control box receives the alarm signal of chlorine leakage alarm, the chlorine absorption device will be automatically put into operation until the chlorine leakage indoor treatment is completed, the operator to the scene operation, the control gear to? Stop? to stop;
2, manual state:
①When need to manually start the chlorine leakage absorption device, turn the control gear to ? Manual? state, press? Fan start? button and? button and the solution pump start button. button;
②When stopping, press the? fan stop button and the button and the solution pump start button. button and the solution pump start button. button. Usually this function is used when the device can not start normally automatically or when the equipment is overhauled.
3, linkage status:
The control gear to? Linkage? state, press the linkage start, the device will start the pump first, after a delay of a few seconds automatically start the fan, press the linkage stop, the device will stop the fan first, after a delay of a few
seconds automatically stop the pump.
4, remote control status:
The operation of the equipment is controlled by the PLC program.
5, stop state:
When the control gear to? Stop? state, in this state, all operations can not be carried out.
Fourth, maintenance and other notes:
1, the device should be started once a month to test, each time 10 minutes to ensure that the device is in a normal standby state;
2, must ensure that the chlorine leakage absorption device control box for a long period of time to supply power;
3, chlorine and chlorine bottles should be normally closed, especially in the event of chlorine leakage accidents, we must close the door and window immediately to prevent the escape of chlorine. Doors and windows to prevent chlorine from escaping, and start the device for absorption treatment;
4, when a chlorine leakage accident, in addition to immediately start the device for absorption, but also find ways to close the leakage source as soon as possible, in order to effectively deal with chlorine leakage accidents;
5, the level of the absorbing liquid is maintained at 800 millimeters or more, when the level of the liquid height is lower than 800 millimeters, can be supplemented with fresh water to the total liquid level 1000mm;
6, pumps and fans in good condition; usually to carry out routine mechanical and electrical maintenance, to ensure that it can be put into operation at any time;
7, the absorption of liquid corrosive, a small amount of stick to the skin or splash in the eyes; in, immediately with a large amount of water to rinse. Inhalation of the gas evolved from the absorption solution will not cause harm to the body.
V. Troubleshooting and treatment:
1, chlorine leakage, the absorption device can not be self-starting
Solution: check whether the chlorine leakage alarm is normal, the control gear is in the ? Automatic?
Solution: Check whether the chlorine leakage alarm is normal, whether the control gear is in ?
2, fan and pump fault lights on
Solution: check the fan and pump and its control circuit.
3, after the device is running, the absorption of chlorine gas
Solution: check the air inlet is not blocked, the absorption liquid level is normal.
