A large amount of lime-ash are carried with the Heisui River of aeration tower discharge, while having the characteristics that high temperature and pressure.In the related art, Heisui River is by subtracting
It is flashed, is generated largely containing grey saturated vapor, this steam contains a large amount of ash, using into hp flash drum after pressure valve
The problems such as equipment can be caused to block, wear in the process, while Heisui River to valve and pipeline when pressure reducing valve by causing seriously to grind
Damage needs to regularly replace valve internals and pipeline.
Invention content
The purpose of the present invention is to provide a kind of usage on black water methods of the useless pot of band, to solve existing Heisui River to valve
It causes to be seriously worn with pipeline and Heisui River carries out flash distillation by hp flash drum and generates largely containing grey saturated vapor.
To achieve the above object, the present invention provides a kind of usage on black water method of the useless pot of band, the Hei Shuichu of the useless pot of the band
Reason method includes the following steps：
Pending Heisui River is delivered to the useless pot in Heisui River and carries out cooling processing by step a；
Cooling treated Heisui River is delivered to low pressure flash chamber progress first time flash distillation process by step b by pressure reducing valve；
Heisui River after first time flash distillation process is delivered to vacuum flasher and carries out second of flash distillation process, Heisui River by step c
Concentration Heisui River is formed after flash distillation process twice；
The concentration Heisui River of second of flash distillation process is delivered to subsider and is recycled by step d.
Preferably, step d is also executed while executing step a, the saturated vapor generated in the useless pot in the Heisui River is defeated
It send into drum, pure steam is generated by the gas liquid separating function of drum.
Preferably, following steps are also executed while executing step d：Boiler water or desalted water are inputted into the drum,
Moisturizing is carried out to it.
Preferably, following steps are also executed while executing step b：The low flash distillation that will be generated in the low pressure flash chamber
Vapour inputs oxygen-eliminating device and carries out heat exchange with low pressure buck, carries out heat recovery.
Preferably, following steps are also executed while executing step c：The true flash steam that the vacuum flasher is generated
It is discharged after being delivered to condenser cooling.
Preferably, the pending Heisui River comes from gasification furnace Heisui River and/or scrubbing tower Heisui River.
The invention has the advantages that：
The present invention provides a kind of usage on black water method of the useless pot of band, energy may be implemented in the usage on black water method of the useless pot of the band
The cleaning of amount recycles, and effectively improves the utilization rate of energy, extends the service life of equipment.

Specific implementation mode
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
Embodiment 1
As shown in Figure 1, the band gives up, the usage on black water method of pot includes the following steps：
Pending Heisui River is delivered to the Heisui River pot that gives up and 101 carries out cooling processing by step a；
Pending Heisui River comes from gasification furnace Heisui River 107 and/or scrubbing tower Heisui River 108, and Heisui River of high temperature and pressure enters black
Water gives up after pot 101 carries out cooling processing and generates saturated vapor, these saturated vapors is delivered in drum 102, by drum 102
Gas liquid separating function generate clean steam 112, for his equipment utilization.In addition, can also be defeated by boiler water 106 or desalted water
Enter drum 102, moisturizing is carried out to it.The Heisui River pot that gives up 101 is connect with drum 102, pressure reducing valve 105 respectively, and low pressure flash chamber 103 is divided
It is not connect with vacuum flasher 104, pressure reducing valve 105.
Cooling treated Heisui River is delivered to the progress first time sudden strain of a muscle of low pressure flash chamber 103 by step b by pressure reducing valve 105
Steaming is handled；
Due to Heisui River by Heisui River give up pot 101 cooling processing after temperature it is relatively low, Heisui River is by first time flash distillation process
Concentration is improved in the process, while only generating a small amount of steam, is reduced to the abrasion of valve, is extended valve service life.Into
One step, in order to improve the utilization rate of energy, can by the low flash steam 109 generated in low pressure flash chamber 103 input oxygen-eliminating device with
Low pressure buck carries out heat exchange, carries out heat recovery.
Heisui River after first time flash distillation process is delivered to vacuum flasher 104 and carries out second of flash distillation process by step c,
Heisui River forms concentration Heisui River 111 after flash distillation process twice；
Heisui River after first time flash distillation process, during vacuum flasher 104 is by second of flash distillation process
Concentration is further enhanced, and forms concentration Heisui River 111.Meanwhile the true flash steam 110 generated in vacuum flasher 104 conveys
It is discharged after being cooled down to condenser.
The concentration Heisui River 111 of second of flash distillation process is delivered to subsider and is recycled by step d.
The cleaning that energy may be implemented in the usage on black water method of the useless pot of the band of the present invention recycles, and effectively improves energy
Utilization rate extends the service life of equipment.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be modified or is improved, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention belong to the scope of protection of present invention.
