Description
Technical field
The present invention relates to for ammonia device, particularly relate to a kind of low temperature and supply ammonia device continuously, be particularly suited for low temp area.
Background technology
Along with the raising day by day of national environmental standard, for NOxDischarge standard tighten up, for the throwing of thermal power plant's SCR denitration device
Fortune situation is also included in environment monitoring.The fired power generating unit of China's active service is all mounted with that more than denitrification apparatus, and 95% are all adopted at present
Be the SCR denitration technology with liquefied ammonia as reducing agent.Owing to liquefied ammonia has explosion hazard, liquid ammonia storage tank is all outdoor arrangement,
To prevent ammonia accumulation from causing poisoning or blast to facilitate fire-fighting during accident to process simultaneously.
For the severe cold area such as northeast, northwest, winter temperature is on the low side, at April annual November to next year, nighttime temperature warp
Often below-10 DEG C, the coldest monthly mean temperature as little as-20 DEG C, extreme low temperature can reach less than-40 DEG C, and the saturated vapor of liquefied ammonia
Pressure following temperature declines and substantially reduces, and travels under low pressure reduces.Therefore, the liquefied ammonia system of severe cold area the most all can be arranged
Liquefied ammonia transfer pump is to start for ammonia during low temperature.According to fire-fighting and fire safety rules, ammonia tank field distance one away between ammonia district process equipment
As more than 10 meters, centre sets passageway for fire apparatus, and during liquefied ammonia transfer pump is generally disposed between process equipment.Therefore ammonia pump and ammonia
Relatively, liquefied ammonia transfer pump export pipeline is longer and bending is many, and entry resistance is bigger for tank distance.
When temperature is down to-10 DEG C, ammonia tank saturated vapour pressure reduces to 2.908bar (absolute pressure), due to the relatively low pipe of pressure
Roadlock power big now liquefied ammonia again can not flow into liquefied ammonia transfer pump from ammonia tank swimmingly.When temperature is down to-15 DEG C, in ammonia tank
Saturated vapour pressure is down to 2.362bar, and now liquefied ammonia has been difficult to flow into liquefied ammonia transfer pump, when ammonia pump starts, easily sends out
Angry erosion cannot run well, so that entering without continuous print liquefied ammonia in liquid ammonia evaporator, it is impossible to stably supply ammonia to SCR region, from
And cause denitration out of service.Owing to environmental requirement is strict, stopping spray ammonia overlong time and will cause boiler down, power plant not only wants
Bear denitration and move back the environmental protection pressure that fortune is brought, must bear and shut down the economic loss caused.
For solving this problem, project is had to attempt being changed into being suitable for by liquefied ammonia transfer pump as the canned motor pump of cryogen by Ordinary Centrifugal Pumps,
But canned motor pump is to such as entering, and pipeline is arranged, entrance liquid level difference has strict requirements, liquid phase circulation line to be installed and gas phase loop,
Liquid phase circulation line and gas phase loop are drawn contact and pipe arrangement require the highest, difficulty is installed for built ammonia district additional relatively big,
Because liquid ammonia storage tank body cannot increase the mouth of pipe, cofferdam, ammonia district is higher is also difficult to ensure that card pumping intake piping has a down dip feed always, and ammonia district is general
Public for multiple stage unit, unless complete plant shutdown, original ammonia pipeline otherwise can not be transformed.And, if with canned motor pump as low temperature
For ammonia device, in addition it is also necessary to dig a pump near former ammonia tank field nearby and cheat to meet entrance liquid level difference requirement, increase again for rainproof also need
If a pump hole awning, internal being also required in pump hole considers hydrops emission measure.Therefore, Overall Reconstruction not only difficulty is big but also expense
High.
