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 the northern area of 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 the northern area of China.This system and device directly utilizes surrounding air, comes the steam discharge of condensation steam turbine by 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 that participates in heat exchange.
Existing peak cooling device transports by 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, because the atomizer installation site of existing peak cooling device is lower, just be in slightly high position level height of blower fan outlet, so the fine droplet that atomizing forms descent path in the air cooling unit is short, few time of contact with air, thereby be unfavorable for that drop evaporates heat absorption in the air cooling unit, simultaneously, owing to adopt common swirling flow nozzle, stop up easily, and its atomization angle and area flow are less, be to guarantee the spraying water yield and spray effect, the nozzle quantity that needs is more, is two and arranges and put, 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, design a kind of cooling effectiveness height, 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 achieving the above object, peak cooling device for air cooling condenser of the present invention, the blower fan, 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 that comprise the horizontal direction placement that is positioned at the air cooling tubes condenser bottom, wherein, the air cooling tubes condenser internal upper part is equipped with bracing frame, 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.
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, and the interface internal diameter of nozzle is 18-22mm, and the internal diameter of its spout is 2mm.
Wherein, lifted the pipeline that a row has the screw type nozzle on the bracing frame, the injection direction of nozzle is for vertically downward, and the blower fan of bottom exports in the air cooling tubes condenser of below.
Advantage of the present invention and beneficial effect are: vertically the flow of the screw type nozzle of installing is bigger, atomizing effect is good, injection direction is a vertical direction, in the running, the droplet of atomizing thermal air current on heading in the decline process is relative and go, make drop and air stream that time of contact and space more fully be arranged, strengthened the evaporation process of small water droplet, the air themperature of more significant reduction radiator.
Description of drawings
Fig. 1 is the structural representation of peak cooling device for air cooling condenser of the present invention;
Fig. 2 is the screw type nozzle and the cooling water conveyance conduit assembling schematic diagram of peak cooling device for air cooling condenser of the present invention.
Among the figure: 1, screw type nozzle; 2, cooling water conveyance conduit; 3, bracing frame; 4, pipeline elevator; 5, surface-type radiator; 6, the inner blower fan of air cooling tubes condenser; 7, screw type nozzle center conical bore; 8, screw type nozzle flight.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.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.
As shown in Figure 1, the concrete technical scheme of implementing 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 by 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, injection direction is for vertically downward, outlet over against the inner blower fan 6 of the air cooling tubes condenser of below, screw type nozzle 1 can be transformed into kinetic energy with the pressure of water, cooling water is by screw type nozzle center conical bore 7 ejections of screw type nozzle 1, be sprayed into the solid atomized water of wide-angle along the anglec of rotation through 3 circle screw type nozzle flights 8, the single flow of nozzle is 40-60L/min, included spray angle is 120 degree even bigger, the carry of spray is far away, the power of spraying is strong, and 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 relative and go, make drop and air stream that time of contact and space more fully be arranged, strengthened the evaporation process of small water droplet, the air themperature at more significant reduction surface-type radiator 5 places.
The advantage of present embodiment is:
The cooling water of peak cooling device for air cooling condenser can produce good atomizing effect by the screw type nozzle, because select rational ejector position and injection direction, atomized water can be directly relative with hot-air and goes, cooling effect is obvious, 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.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
