The utility model relates to a kind of energy-saving environmental protection device, especially relates to a kind of boiler room feed water pump cooling water circulation utilization apparatus of energy-conserving and environment-protective.
Background technique
The increasing of the external pressure brought along with anxiety and the global warming of world energy sources resource, energy saving, protection of the environment has become the very important significant problem in countries in the world.
In general, gas fired boiler is a kind of by making combustion gas burn to add hot fluid together with air, such as water, and improves room temperature by circulation heated fluid or provide the device of hot water.Gas fired boiler can be applicable to Workshop Production or life heating.In this gas-fired Boiler System, by fluid from fluid source through fluid input delivering fluids case. deliver to water supply in fluid tank by recycle pump by fluid output displacement fluids case, and flow to heat exchanger, the heating pipeline internal circulation flow then arranged along room wall, thus room is heated.
Feed water pump in boiler room is generally for gas fired boiler provides water source, because the conveying water yield is large, feed water pump power is high, for avoiding its overheated use, usually need to arrange cooling system to feed water pump, be generally adopt cooling water to cool, existing feed water pump cooling water is directly emit after finishing using, and causes waste.
Summary of the invention
The purpose of this utility model is exactly provide a kind of boiler room feed water pump cooling water circulation utilization apparatus of energy-conserving and environment-protective of energy-conserving and environment-protective to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of boiler room feed water pump cooling water circulation utilization apparatus of energy-conserving and environment-protective, it is characterized in that, comprise wet pit, cooling water inlet pipe, cooling water outlet pipe, inlet valve, flowing water Valve, described wet pit connects the cooling water intake of feed water pump by cooling water inlet pipe, connected the cooling water outlet of feed water pump by cooling water outlet pipe, and be provided with inlet valve and flowing water Valve on cooling water inlet pipe and cooling water outlet pipe.
Described wet pit is also connected with wet pit water-adding pipe, and is provided with wet pit water-feeding valve on wet pit water-adding pipe.
Described wet pit sidewall bottom is provided with water supplement port, and this water supplement port connects wet pit water-adding pipe.
Described wet pit sidewall is provided with and water outlet and a water intake, and wherein the level height of water outlet is lower than the level height of described water intake, and described water outlet connects cooling water inlet pipe, and described water intake connects described cooling water outlet pipe.
Described inlet valve, flowing water Valve are connected central control unit respectively with wet pit water-feeding valve.
Described wet pit is provided with relief valve.
Described feed water pump is DG type system horizontal single-suction multilevel fractional centrifugation pump, comprises DG25-80, DG45-80, DG85-80, DG150-100 etc.; The flow of feed water pump is 25-150m 3/ h, lift can reach 480 ~ 1100 meters.Can carry the high temperature clear water of less than 280 DEG C, when to boiler feed water, the temperature of the cooling water after cooling feed water pump is generally at 60 ~ 70 DEG C, and the volume of described wet pit is set to 5 ~ 20m 3, generally do not need separately to establish heat exchanger to carry out cooler to cool back the water got back, because wet pit, and cooling water inlet pipe, the tube side of cooling water outlet pipe is enough to make circulating water be returned to normal temperature state when next time cools under this volume.In addition, by central controller controls inlet valve, flowing water Valve and wet pit water-feeding valve, when in wet pit, temperature is higher than 40 DEG C, open large inlet valve, flowing water Valve, the flow of circulating water is made to be 1 ~ 2 times of feed water pump flow, or strengthen the open amount of wet pit water-feeding valve, the temperature in wet pit can be lowered.
Compared with prior art, the utility model has the following advantages:
1. arrange wet pit, wet pit inner cooling water is delivered to feed water pump by water pump, and feed water pump drain opening pipeline is connected to wet pit, and formation recycles, and effectively reduces costs, energy-conserving and environment-protective.
2. wet pit sidewall is provided with water intake, water outlet, water supplement port, and arranges the position of three mouths of pipe according to certain water level, utilizes the self gravitation auxiliary water pump of water to form circulation, energy-saving and cost-reducing;
3. do not need separately to establish heat exchanger, the circulating cooling of cooling water can be realized by the circulation of self.
