Technical field
This utility model belongs to technical field of thermoelectricity, the water side overvoltage unloading peace of more particularly to a kind of water cooling cold cinder device
Full device.
Background technology
When steam power plant's fluid bed boiler water-cooling formula slag cooler normally runs, the high temperature warm sludge in burner hearth passes through slag cooler roller
It is delivered on defeated slag crust band, then be transported away by defeated slag crust band；Period using the cooling water flowing through slag cooler cylinder body outer wall, by high temperature
The heat absorption of warm sludge is taken away, and keeps in the zone of reasonableness of slag reduction of slag cooler outlet.So on the one hand reclaim the row of taking away
The heat loss of slag, on the one hand ensures that defeated slag crust band does not contact high temperature warm sludge and produces danger.
Existing slag cooler is not because considering the probability of water side overvoltage when equipment manufacturer designs, so not providing reliable guarantor
Shield.When slag cooler normally runs, cooling water flows through slag cooler, and arranged at safety valve is in Normal Shutdown state；But work as slag cooler running
If in occur unexpected lead to cooling water Inlet and outlet water valve closing, the cooling water heating that cylinder retains is boosted to very high by high temperature warm sludge
Pressure, but nowhere pressure release, may result in slag cooler water side and the swollen bad equipment of overvoltage or the danger bursting occur.
For that purpose it is necessary to safe design is re-started to the water lateral line of slag cooler, thoroughly solve slag cooler water side overvoltage and damage
The potential safety hazard of bad equipment, and finally realize the safe and stable operation of slag cooler system equipment.
Utility model content
The purpose of this utility model is to provide a kind of water side overvoltage of water cooling cold cinder device to unload safety device, by
The water side overvoltage unloading safety device of slag cooler, that is, be arranged on pipeline section before slag cooler outlet pipeline valve, direct by threeway
Connect and a spring loaded safety valve is installed, if solve to occur in existing slag cooler running surprisingly leading to cooling water to pass in and out
Penstock is closed, and the cooling water heating that cylinder retains is boosted to very high pressure by high temperature warm sludge, but nowhere pressure release, may result in
The swollen bad equipment of overvoltage or the dangerous problem bursting in slag cooler water side.
For solving above-mentioned technical problem, this utility model is achieved through the following technical solutions:
This utility model is a kind of water side overvoltage unloading safety device of water cooling cold cinder device, including slag cooler and slag cooler
On inlet pipeline and outlet pipeline；Isolating valve, going out between described slag cooler and isolating valve, are provided with described outlet pipeline
Spring loaded safety valve is provided with water lines.Slag cooler water side overvoltage unloading safety device is mounted in slag cooler cooling water water outlet
It is ensured that energy direct feeling, to the cooling water chamber pressure of cylinder side, provides protection in time on pipeline section before pipeline barrier valve.
Further, the feeding mouth of described slag cooler is connected with the slag notch of boiler, and the discharging opening of described slag cooler is located at
Above defeated slag crust band.
Further, described spring loaded safety valve is fixed on outlet pipeline by three way cock, with slag cooler water side chamber
Do not set pass close point between body space it is ensured that the relief valve of device can play a protective role conscientiously, will not lead to because closing by mistake protect
Shield exits situation.Eliminate the water side valve door being likely to occur during slag cooler runs to close by mistake, lead to the swollen evil idea of slag cooler water side overvoltage to set
The standby or danger that bursts is it is ensured that the safe and stable operation of slag cooler system equipment.
This utility model has the advantages that
This utility model passes through to unload safety device in the water side overvoltage of slag cooler, that is, be arranged on slag cooler outlet pipeline valve
In front of the door on pipeline section, it is directly connected to a spring loaded safety valve is installed by threeway；When slag cooler normally runs cooling water flow through cold
Slag device, arranged at safety valve is in Normal Shutdown state；If but leading to cooling water inlet/outlet valve when appearance is unexpected in slag cooler running
Door is closed, and the cooling water heating that cylinder is retained by high temperature warm sludge boosts to after certain pressure, relief valve be actionable pressure release it is ensured that
The safety of slag cooler cylindrical apparatus, prevents the swollen bad equipment of slag cooler water side overvoltage or the danger bursting.Guarantee slag cooler system
The safe and stable operation of system equipment.
Certainly, implement arbitrary product of the present utility model to it is not absolutely required to reach all the above advantage simultaneously.
