Abstract
The utility model relates to a hydraulic fan cooling tower with a bypass safety control device. The cooling tower comprises a tower body, a water tank arranged on the bottom of the tower body, a water turbine arranged on the top of the tower body and fan blades driven by the water turbine, wherein a water inlet of the water turbine is connected with a main water inlet pipe and a water outlet of the water turbine is connected with a water sprinkling system. The cooling tower has the following advantages: 1. the maintenance and repair work on the cooling tower can be finished without influencing the running of the whole circulating water system; 2. the process requirement of the cooling circulating water on the temperature reduction can be regulated without influencing the running of the whole circulating water system; 3. a bypass pipe can be used to release pressure to prevent the cooling tower damage when the pressure of the circulating water system exceeds the rated requirement; and 4. under other special conditions, when the fan blades need to stop rotation, a bypass line can be used to ensure the normal running of the cooling tower.
Description
Technical field
The utility model relates to a kind of cooling tower, specifically, relates to a kind of hydraulic fan cooling tower with the bypass safety control.
Background technology
Hydraulic fan cooling tower is the cooling device of commonly using, because it possesses the advantages such as efficient, energy-conservation, low noise, so application is very extensive.In the prior art, hydraulic fan cooling tower mainly comprises tower body, is located at the pond of tower body bottom, is located at the hydraulic turbine at tower body top and the fan blade that is driven by the hydraulic turbine, and the water inlet of the hydraulic turbine connects main water inlet tube, and the discharge outlet of the hydraulic turbine connects sprinkler system.
There is following problem in existing hydraulic fan cooling tower: 1, cooling tower need to carry out regular maintenance and maintenance, at this moment, will close down main water inlet tube to hydroturbine water intake, yet, in case stop to hydroturbine water intake, will affect the operation of whole circulation; When 2, the cooling circulating water technological requirement is adjusted temperature drop, such as in the winter time, cooling circulating water technological requirement temperature drop can not be too low, freeze preventing, at this moment, will reduce the rotating speed of fan blade to the inflow of the hydraulic turbine by reducing main water inlet tube, and so, can affect equally the operation of whole circulation; 3, do not have the overload protection measure, when the pressure of circulation surpassed specified the requirement, cooling tower can be impaired, even paralysis.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and a kind of hydraulic fan cooling tower with the bypass safety control is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of hydraulic fan cooling tower with the bypass safety control, comprise tower body, be located at tower body bottom the pond, be located at the hydraulic turbine at tower body top and the fan blade that is driven by the hydraulic turbine, the water inlet of the hydraulic turbine connects main water inlet tube, the discharge outlet of the hydraulic turbine connects sprinkler system, it is characterized in that: be connected with bypass pipe on the described main water inlet tube, the upper end of bypass pipe connects sprinkler system.
Say further:
Main water intaking valve is installed on the described main water inlet tube, and described main water intaking valve is installed in the top at bypass pipe and main water inlet tube interface position; On the described bypass pipe bypass control valve (BCV) is installed.
The top of described sprinkler system is provided with water collection device.
The below of described sprinkler system is provided with filler.
Described sprinkler system comprises that outlet pipe, water distributor and several are evenly distributed on the fountain head on the water distributor, the sealing of described outlet pipe bottom, and the top is connected on the discharge outlet of the hydraulic turbine; Described water distributor is installed in the bottom of outlet pipe, and is attached thereto logical; The upper end of described bypass pipe is connected with water distributor.
Owing to adopted technique scheme, compared with prior art, the utility model has been set up the bypass pipe that connects sprinkler system at main water inlet tube, have the following advantages: when 1, cooling tower carries out regular maintenance and maintenance, open first bypass control valve (BCV), close again main water intaking valve, make water flow into sprinkler system by bypass pipe, carry out heat exchange from the fountain head pouring to filler, in the situation that does not affect whole circulation operation, finish maintenance and service work to cooling tower; 2, in the winter time, when the cooling circulating water technological requirement is adjusted temperature drop, can open first bypass control valve (BCV), close again the main water intaking valve of certain angle, reduce the rotating speed of fan blade to the inflow of the hydraulic turbine by reducing main water inlet tube, like this, neither can affect the operation of whole circulation, can realize that again the cooling circulating water technological requirement is to the adjustment of temperature drop; 3, when the pressure of circulation surpasses specified the requirement, open bypass control valve (BCV), bypass pipe can play the overload protection effect of pressure release, in order to avoid cooling tower is impaired; 4, at other in particular cases, in the time of need to stopping the fan blade rotation, can guarantee by bypass the normal operation of cooling tower.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
