The drainage procedure of condensed water under normal circumstances is illustrated below:
High-temperature flue gas, into secondary heat exchanger, preheats heating return water, due to this after first-class heat exchanger exchanges heat
When flue-gas temperature it is low, can a large amount of condensed waters are generated in secondary heat exchanger, condensed water can flow to water along condensate draining pipe
Feng Zhong, when the water level savings in water seal is to when being more than the liquid level of overflow port, the water in water seal will be from the discharge outlet of water seal
Outflow.
The process in case of emergency drained is illustrated below:
1, when the discharge outlet due to the impurity water seal in condensed water is blocked or freezes, condensed water can be in the entire system
It is cumulative, when condensed water savings is to the bottom of secondary heat exchanger, due to whole section of water route conduction, so that secondary heat exchanger bottom
Liquid-level switch contact and water seal on liquid-level switch contact conducting, unit alarmed and shut down, and passes through condensation in this way
The water route of water is connected to judge that emergency occurs in complete machine condensate water discharging system, immediately after stopping alarm, in order to avoid generate more
More condensed waters lead to the damage of unit combustion chamber water inlet and component.
If 2, install it is lack of standardization cause rainwater enter from smoke pipe sealing room or unit inner water tube infiltration, explosion cause it is close
The indoor a large amount of ponding of envelope, the hydraulic pressure switch in water seal can be with real-time detection to indoor water pressures are sealed, if working as hydraulic pressure at this time
When reaching certain numerical value, compressor emergency shutdown alarms and opens hydraulic pressure switch, so that the water energy inside sealing is enough in time from the first draining
Mouth is discharged in water seal, is then discharged from the discharge outlet of water seal.
As interchangeable embodiment, the second liquid-level switch is arranged on condensate draining pipe 45, the second liquid-level switch
It is arranged higher than overflow port, as long as the liquid level of i.e. trigger protection is on the liquid level of overflow port.
It can be seen from the above description that the above embodiments of the utility model realize following technical effect:
Hydraulic pressure switch is set in the bottom wall setting discharge outlet of sealing room and in water seal, seals indoor ponding when detecting
Hydraulic pressure when reaching a certain level, alarmed unit, shut down, and open hydraulic pressure switch in time, water is discharged in water seal, with
Condensed water empties together；And it is respectively provided with liquid-level switch in water seal and secondary heat exchanger or condensate draining pipe, it can be simultaneously
It detects and seals indoor ponding caused by water stemming or other reasons, then machine group alarm and shut down, above structure is using dual
Ponding safeguard protection, avoids the secondary damage to unit components, and unit operational safety is provided more into the protection of level-one.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
