Cooling water pump backwater draw water not smooth problem.
Next, will be horizontal to the mechanical type being applied under the conditions of placing in the air channel of subway underground station and adapting to one-way gas flow
Stream cooling tower is described in detail:
It is single for the mechanical type crossflow cooling tower under the conditions of placing in the air channel of subway underground station and adapting to one-way gas flow
Side air intake, the cross flow cooling tower of top air-out, such as square cooling tower.As Figure 1-3, this cross flow cooling tower and biography
The double-faced ventilated cross-flow type of system or counterflow cooling tower contrast, other side-closed in the side of tower body 1 shell, a side is opened
Put, open side constitutes air inlet, and top arranges exhaust outlet, and exhaust outlet arranges frequency conversion exhaust blower 2, including blade, blade even
Connection device and the motor of driving blade, exhaust blower 2 and motor power connector, provide air pressure by power drive, and air is only
Enter from side, top is discharged, and enables cooling tower to be suitable for the one-way gas flow condition of subway exhausting duct, is more easy to carry out air-flow group
Knit, so ensure the intake of cooling tower and air draft smooth it is ensured that the cooling effectiveness of cooling tower.
Tower body 1 combines air channel and arranges parallel works, solves the problems, such as the hot gas re-flow being also easy to produce in confined space.Tower body 1
For stainless steel square body, increased tower body fire protecting performance, fire protection requirement when solving the problems, such as to be positioned in underground air duct.
In tower body 1, the stainless filler of filling 5, there is heat exchange in cold water and air in filler 5, sets on the top of filler 5
Put water distributing mechanism, water distributing mechanism is connected with water inlet pipe, water-collecting tray, especially deep water type water-collecting tray are set in the bottom of filler 5, catchment
Disk is connected with outlet pipe, and its effect is above it was mentioned that the invention that here is omitted.
Wherein, water distributing mechanism includes multiple water distributors 8, water distributor 8 has downward water distributing pore, in tower body 1, from upper
Uniformly spray water into filler 5 downwards.In order to uniformly spray water, the distribution mode of water distributor 8 needs for non-uniform manner, such as: all
Water distributor 8 is evenly arranged on the cross section of tower body 1；Or, all water distributors 8 are outwards uniform from the center of tower body 1 cross section
Radiation.
The top of tower body arranges more than one water inlet, arranges 2 water inlets in the present embodiment, water inlet respectively with
Water inlet pipe and water distributor connect.Current enter water distributor from water inlet pipe through water inlet 3.
Cooling tower frequency conversion exhaust blower 2 power are larger, can overcome gas-flow resistance in the more airtight narrow space in underground and cold
But tower internal airflow resistance it is ensured that cooling tower enter exhaust air rate, and the damp-heat air that cooling tower is produced discharges air channel, meanwhile,
Exhaust blower 2 is frequency conversion fan, when air conditioning system load is relatively low, can reduce rotation speed of fan according to duty requirements and adjust into air draft
Amount, accomplishes energy efficient；When cooling tower outer gas stream resistance is less, rotation speed of fan and wind can be adjusted according to gas-flow resistance situation
Machine blade angle, reduces the air pressure that blower fan produces, to ensure blower fan in best efficiency point work, the drift ice of minimizing cooling tower, section
About use water.
, three sides of tower body completely enclose taking square cooling tower as a example, and only side opens, and open side constitutes air intake
Mouthful, outside air enters in open side, is horizontally through filler 5, completes to steam with the cooling water that flows from top to bottom in filler 5
Dissipate the heat exchanges such as heat, contact radiating.
In order to increase the efficiency of heat exchange, filler 5 includes multilamellar stainless steel helices, and multilamellar is using hole stricture of vagina form, stacked
Density arranged for interval.Each packing layer extends to the top of tower body 1 from the bottom of tower body 1.All packing layers are arranged in parallel, and with
The axial direction of tower body 1 is at an acute angle, that is, be obliquely installed.
Based on above-mentioned mechanical type crossflow cooling tower, its operation principle is:
Outside air enters from air inlet (inlet side), is horizontally through filler 5, cooling water enters through water inlet 3 from water inlet pipe
Enter cooling tower water-distributing device, cooling water is uniformly sprayed in stainless steel helices 5 by water-distributing device, cooling water in filler 5 with
After air is evaporated the heat exchanges such as radiating, contact radiating, water temperature reduces, and flowing from top to bottom is pooled to water under gravity
Water-collecting tray 7, the cooling water in water-collecting tray 7 flows out cooling tower by the outlet pipe that outlet 6 connects；Outside air is through heat exchange
Afterwards, under the blast that blower fan is formed drives, discharge at cooling tower top, enter external environment.
Cooling tower is provided with necessary apparatus for examination and repair, including maintenance cat ladder 4 and manhole 9, when the part located at tower body 1 top
Go wrong need maintenance when, maintainer can using maintenance cat ladder 4 on to above cooling tower；Manhole 9 is located at cooling
Tower side, facilitates maintainer on the ground to being checked in cooling tower and overhaul.
The various embodiments that this utility model provides can be mutually combined as needed in any way, is combined by this
The technical scheme arriving, also in the range of this utility model.Obviously, in the situation without departing from spirit and scope of the present utility model
Under, those skilled in the art can carry out various change and modification to this utility model.If changed to of the present utility model these
Dynamic and modification is within the scope of claim of the present utility model and its equivalent, then this utility model also will comprise this
A little changes and modification.
