Description
Technical field
This utility model relates to a kind of precombustion chamber cooling system, belongs to pulverized-coal fired boiler technical field.
Background technology
For the ease of the raw stove of igniting and raising coal combustion rate, the most all one can be arranged in the main chamber of boiler
Precombustion chamber, precombustion chamber is higher compared with the less internal temperature in main chamber space, and coal dust can be heated rapidly in combustor and ignite.
But the structure of precombustion chamber itself is brought bigger test by high temperature, outside in current industry, commonly used cooling water is to precombustion chamber
Wall cools down, and its drawback is: (1) cooling effect is poor；(2) between cooling water and the precombustion locular wall of high temperature, the temperature difference is relatively big,
The cooling water capacity easily undergoes phase transition formation bumping, and equipment is impacted damage；(3) cooling water is not circulated utilization and causes resource
Waste.
Utility model content
For the problems referred to above, this utility model provides a kind of precombustion chamber cooling system, its object is to: ensure cooling effect
Really, maintain equipment continual and steady, improve cooling water application efficiency.
Technical solution of the present utility model:
A kind of precombustion chamber cooling system, it is characterised in that: described cooling system includes that cooling coil, described cooling coil twine
Being wound on precombustion chamber outer wall, cooling coil bottom is connected with cooling water inlet pipe, cooling coil top and cooling water outlet pipe phase
Even, described cooling water outlet pipe being provided with flow control valve, described outlet pipe connects circulating water reclamation pond, circulating pump and circulation
Pond connects and by water inlet pipe, recirculated water is pumped into cooling coil, forms a closed-loop path.
The described cooling coil optimized is the double-decker with inner tubal wall and outer tube wall, forms one between two-layer tube wall
Chuck, described chuck bottom is connected with blast pipe, and described chuck top is connected with discharge pipe, and described blast pipe is connected with blower fan.
Optimize, described jackets outer wall is provided with radiating fin.
Optimizing, institute's circulating water reclamation is provided with heat sink on pond.
Described heat sink is cool breeze tower or flusher.
In order to accurately regulate the aperture of valve, thermometer will be provided with on described cooling water outlet pipe.
The beneficial effects of the utility model:
This utility model, by arranging double-deck cooling coil on precombustion chamber outer wall, is passed through recirculated water inside coil pipe, double-deck
It is passed through air in chuck precombustion chamber is cooled down, forms air cushioning between cooling water and the precombustion chamber outer wall of high temperature, keep away
Exempt from water body generation bumping in pipe, increased cooling effect and improve stabilization of equipment performance；Circulating water outlet pipe arranges regulation valve, energy
Enough cooling water flow velocity is adjusted, circulating water pool arranges heat sink, it is possible to effectively reduce circulating water temperature, increase cold
But effect.
