Description
Technical field
The present invention relates to the power station direct air-cooling condenser system, be specifically related to a kind of peak cooling device for air cooling condenser.
Background technology
Power station direct air-cooling condenser system (ACC) is the emerging in recent years water-saving steam condensation technology in north China thermal power plant.At present there has been the unit of nearly 200 different capabilities to use this technology, obtained good water-saving benefit in north China.This system and device directly utilizes surrounding air, comes the steam discharge of condensation steam turbine through surface-type heat exchanger.In the summer high temperature period, because environment temperature is higher,, in ACC air cooling unit, install peak cooling device additional usually for promoting the exchange capability of heat of heat exchanger, adopt the principle of spraying humidification and evaporation heat absorption, reduce the ambient air temperature of participating in heat exchange.
Existing peak cooling device transports through pipeline and swirling flow type nozzle and sprays cooling water; This cooling water conveyance conduit is arranged in the inner blower fan of air cooling tubes condenser exit; Nozzle spray direction is a horizontal direction; The atomized water of ejection with the air contact process in evaporation heat absorption, can reduce the air themperature of radiator, improve the heat-sinking capability of radiator.But,, just be in slightly high position level height of blower fan outlet because the atomizer installation site of existing peak cooling device is lower; So the fine droplet that atomizing forms descent path in the air cooling unit is short, and is few time of contact with air, thereby is unfavorable for that drop evaporates heat absorption in the air cooling unit; Simultaneously, owing to adopt common swirling flow nozzle, easy blocking; And its atomization angle and area flow are less, and for guaranteeing the spraying water yield and spray effect, the nozzle quantity that needs is more; Be two arranged, the respective branch pipeline is more, installs complicated.
Summary of the invention
The objective of the invention is to overcome defective of the prior art, it is high to design a kind of cooling effectiveness, and system simplification, runner are difficult for stopping up, and the atomizing area increases peak cooling device for air cooling condenser convenient for installation and maintenance.
For realizing above-mentioned purpose; Peak cooling device for air cooling condenser of the present invention; Comprise the blower fan of the horizontal direction placement that is positioned at the air cooling tubes condenser bottom, the surface-type radiator that is positioned at the air cooling tubes condenser surface, the cooling water conveyance conduit of air cooling tubes condenser inside and the nozzle that is installed in cooling water conveyance conduit exit; Wherein, The air cooling tubes condenser internal upper part is equipped with bracing frame, and the cooling water conveyance conduit is suspended on the bottom of bracing frame, and the nozzle in cooling water conveyance conduit exit is the screw type nozzle of vertically installing; The interface internal diameter of said nozzle is 18-22mm, and the internal diameter of its spout is 2mm, and the single flow of nozzle is 40-60L/min; Lifted a row on the support frame as described above and had the pipeline of screw type nozzle, the injection direction of nozzle is for vertically downward, and said nozzle blower fan of bottom in the air cooling tubes condenser of below exports.
Wherein, bracing frame is installed in air cooling tubes condenser internal upper part 1/3 and highly locates.
Wherein, nozzle is the screw type nozzle with 3 circle flights, and its 3 circle flight is at the spout place of nozzle.
Advantage of the present invention and beneficial effect are: the flow of the screw type nozzle of vertically installing is bigger; Atomizing effect is good, and injection direction is a vertical direction, in the running; The droplet of atomizing in the decline process with head-on and on thermal air current go relatively; Make drop and air stream that time of contact and space more fully arranged, strengthened the evaporation process of small water droplet, reduce the air themperature of radiator more significantly.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, specific embodiments of the invention further describes.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Shown in accompanying drawing 1; The technical scheme of practical implementation of the present invention is: highly locate (about 7-9m) in air cooling tubes condenser inner and upper 1/3 bracing frame 3 is installed; Cooling water conveyance conduit 2 is suspended on the bottom of bracing frame 3 through pipeline elevator 4; Cooling water conveyance conduit 2 is pipelines that a row is arranged in juxtaposition, and its exit is equipped with screw type nozzle 1.Screw type nozzle 1 is vertically installed, and injection direction is for vertically downward, over against the outlet of the inner blower fan 6 of air cooling tubes condenser of below; Screw type nozzle 1 can be transformed into kinetic energy with the pressure of water, and cooling water is sprayed into wide-angle solid atomized water along the anglec of rotation through 3 circle screw type nozzle flights 8 through screw type nozzle center conical bore 7 ejections of screw type nozzle 1; The single flow of nozzle is 40-60L/min; Included spray angle is 120 degree even bigger, and the carry of spray is far away, and power is strong thoroughly in spray; Single spraying area coverage is big, can adapt to 1-10bar hydraulic pressure working range.Wherein, the screw type nozzle can be selected the LX type spiral nozzle of Shanghai occasion wound metallic article Co., Ltd for use.
In the running; Through the droplet of screw type nozzle atomization in the decline process with head-on and on the steam turbine thermal air current of discharging go relatively; Make drop and air stream that time of contact and space more fully arranged; Strengthen the evaporation process of small water droplet, reduced the air themperature at surface-type radiator 5 places more significantly.
The advantage of present embodiment is:
The cooling water of peak cooling device for air cooling condenser can produce good atomizing effect through the screw type nozzle; Because select rational ejector position and injection direction; Atomized water can be directly go with hot-air relatively, and cooling effect is obvious, and nozzle quantity reduces half than old swirling flow or once-through type nozzle quantity; And corresponding minimizing lateral quantity and suspension and support quantity, make the installation of nozzle quantity and lateral be more prone to.
