Technical field
The utility model relates to industrial circulating water energy-saving equipment technical field, is specifically related to a kind of cooling tower circulating water excess pressure and utilizes device.
Background technology
The pressure energy more than needed of the circulation of existing enterprise, mainly come from the potential energy that cooling water produces when high-order heat transmission equipment flows down and enters cooling tower, in most cases in order to ensure the water-distributing device that cooling water does not destroy by rush of water in tower, also need to consume this part energy with valve; In addition, because when design cycle water system, general computing system resistance estimates by rule of thumb, also will consider safety coefficient, and the water pump rated head selected is general just bigger than normal, and the actual energy being supplied to recirculated water of water pump just necessarily has more than needed.
But this part overbottom pressure is not generally all recycled and utilizes and waste in the circulation of existing most of enterprise.As shown in Figure 1, cooling-tower circulating water device is primarily of water grain bin, fresh water pump, cooling tower and water circulating pump composition, and recirculated water directly enters cooling tower by return main, has some driven by motor blower fan runnings, cool recirculated water above cooling tower.Such circulating water device, not only makes system overbottom pressure waste, but also will spend into and originally consume this part energy.
Utility model content
The utility model provides a kind of cooling tower circulating water excess pressure and utilizes device, and the circulating water excess pressure existed to solve prior art can not get the problem recycled.
The utility model device is primarily of water grain bin, some fresh water pumps, cooling tower and some water circulating pumps composition, some blower fans are set above cooling tower, solve on return main that technical scheme that its technical problem adopts is cooling tower and some backwater bypasses are set, in every bar backwater bypass level, a pipe type hydraulic turbine is axially set, the main shaft of pipe type hydraulic turbine is connected with the shaft coupling of the blower fan on cooling tower, and the liquid outlet of pipe type hydraulic turbine is communicated with cooling tower by backwater branch road.
A butterfly valve is installed in the bypass of above-mentioned every bar backwater, butterfly valve is directly communicated with cooling tower by pipeline, for controlling and regulating the water yield entering pipe type hydraulic turbine, open this butterfly valve opening large, the water yield that can reduce to enter pipe type hydraulic turbine can reduce pipe type hydraulic turbine rotating speed, avoids blower fan to overrun, during pipe type hydraulic turbine maintenance, can open this butterfly valve, current enter cooling tower by former pipeline.
The utility model device utilizes the pressure energy more than needed in existing cooling-tower circulating water device to promote pipe type hydraulic turbine wheel rotation, then drives to blower fan and make it operate to cool recirculated water, and concrete grammar step is as follows:
Recirculated water is delivered in return main by water circulating pump, controlled by the butterfly valve that backwater bypass is installed and regulate the water yield entering pipe type hydraulic turbine, recirculated water is by the valve in backwater bypass and telescopic joint, horizontal axis is introduced in pipe type hydraulic turbine, driving pipe type hydraulic turbine does work, current are delivered in cooling tower by backwater branch road by pipe type hydraulic turbine again, pipe type hydraulic turbine is arranged on the motor place of former blower fan, the main shaft of pipe type hydraulic turbine is directly connected with the original shaft coupling of cooling tower, by original power transmission shaft, decelerator drives the running of the blower fan of cooling tower to carry out cooling down to recirculated water, when pipe type hydraulic turbine overhauls, can opened butterfly valve, recirculated water directly enters in cooling tower.
The utility model project belongs to overbottom pressure and utilizes project, and before technological transformation, power consumption is 1330.91 ten thousand degree circulating water device year; Year water consumption 120,000 tons.After technological transformation device year power consumption 1030.91 degree; Year water consumption 120,000 tons.Known project year economizes on electricity 3,000,000 degree, and amount to standard coal 1050tce, energy-saving effect is remarkable.
The utility model achieves the recycling of industrial circulating water overbottom pressure, utilize circulating water excess pressure to promote turbine impeller to rotate, driving to blower fan again makes it operate, thus substitutes the motor being used for driving blower fan that traditional cooling tower is installed, and reaches the object of saving electric energy.
