Description
Technical field
The utility model relates to a kind of energy conserving system, relates to specifically a kind ofly utilize the smoke pipe waste heat of steam boiler by energy-saving appliance, condenser the energy conserving system of heat recovery.
Background technology
Existing steam boiler generally includes one and is placed in the combustion chamber in housing and the smoke pipe with combustion chamber, smoke pipe is immersed in water, high-temperature flue gas is produced after gas mixture being spurted combustion chamber combustion by burner, high-temperature flue gas, carrying out heat exchange by water during smoke pipe and outside smoke pipe, is heated into water the steam of 175 degrees centigrade.High-temperature flue gas in smoke pipe forms the high-temperature tail gas also with more than 300 degrees Celsius after carrying out heat exchange with the water in body of heater, as the words of putting of truly running in can cause great waste, and again the water seethed with excitement in the high-temperature tail gas of 300 degrees Celsius and body of heater is carried out the words efficiency of heat exchange can be very low, if and the cold water of the flue gas of 300 degrees Celsius and normal temperature is carried out heat exchange efficiency can improve a lot, for this reason, be badly in need of wanting a kind of flue gas that can high-temperature flue gas be utilized after carrying out heat exchange with the water in body of heater also to have the temperature of more than 300 degrees Celsius to carry out the steam boiler energy-saving system of high efficiente callback.
Utility model content
For overcoming above-mentioned defect, the utility model aims to provide a kind of energy conserving system utilizing the steam boiler of the energy of energy maximal efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of energy conserving system of steam boiler, comprise a steam boiler, the smoke pipe afterbody of described steam boiler is connected with an energy-saving appliance, described energy-saving appliance is by an outlet pipe one and steam boiler intracavity inter-connection, and described energy-saving appliance is connected with a softened water tank by a feed pipe one; Described feed pipe one is provided with an infusion pump one.
The energy conserving system of steam boiler described in the utility model also comprises a condenser, smoke pipe afterbody in described energy-saving appliance is connected with condenser, described condenser is connected with feed pipe one by a feed pipe two, described condenser is connected with feed pipe one by an outlet pipe two, described feed pipe two, be communicated with an isocon between outlet pipe two and the tie point of feed pipe one, described isocon is provided with a check valve; Described feed pipe two is provided with an infusion pump two, and described feed pipe one is provided with a stop valve between infusion pump one and isocon.
Have employed the energy conserving system of steam boiler of the present utility model, cold water is first utilized the first steam boiler inner chamber that reinjects after energy-saving appliance and condenser carry out being heated into warm water of high-temperature tail gas, steam is formed, both environmental protection after warm water in steam boiler is more easily seethed with excitement, energy-conservation again.

Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of energy conserving system of steam boiler, comprise a steam boiler 1, the high-temperature flue gas that described steam boiler 1 utilizes burner to spray flows into the smoke pipe in its body of heater, and utilize the water in smoke pipe and body of heater to carry out heat exchange, water is seethed with excitement and produces steam, and flowed out by jet chimney.Flue gas in smoke pipe also has higher temperature after carrying out heat exchange with the water in body of heater, and innovative point of the present utility model is just the tail gas utilizing these higher temperatures.
Its technical scheme is: the smoke pipe afterbody of described steam boiler 1 is connected with an energy-saving appliance 2, high-temperature tail gas in smoke pipe passes into the smoke pipe in energy-saving appliance 2, described energy-saving appliance 2 is by an outlet pipe 1 and steam boiler 1 intracavity inter-connection, and described energy-saving appliance 2 is connected with a softened water tank 5 by a feed pipe 1; Described feed pipe 1 is provided with an infusion pump 1.During specific works, start infusion pump 1, cold water in softened water tank 5 is first flowed in energy-saving appliance 2 by feed pipe 1, and cold water and the high-temperature tail gas in energy-saving appliance 2 internal flue carry out becoming warm water after heat exchanges, and then flows into steam boiler inner chamber by outlet pipe 1 and is heated rear generating steam further.Because the water entering steam boiler 1 inner chamber is tentatively heated to be warm water, warm water is more easily heated to boiling, thus greatly saves the time of heating, also saves the valuable energy simultaneously.
Due to after heat exchange, the tail gas flowed out in energy-saving appliance 2 also has certain temperature, be generally 150 degrees centigrade, if be directly discharged in air, both contaminated air, waste energy again, for this reason, another innovative point of the energy conserving system of steam boiler of the present utility model is that it also comprises a condenser 6, smoke pipe afterbody in described energy-saving appliance 2 is connected with condenser 6, described condenser 6 is connected with feed pipe 1 by a feed pipe 27, described condenser 6 is connected with feed pipe 1 by an outlet pipe 28, described feed pipe 27, an isocon 14 is communicated with between the tie point of outlet pipe 28 and feed pipe 1, described isocon 14 is provided with a check valve 15, described feed pipe 27 is provided with an infusion pump 2 13, and described feed pipe 27 is provided with a stop valve 9.During specific works, open infusion pump 2 13, ON-OFF valve 9 is closing one-way valve 15 also, like this, the cold water flowed out in softened water tank 5 first enters condenser 6 by feed pipe 27, heat up after carrying out heat exchange with the tail gas in the smoke pipe in condenser 6 more also low temperature warm water, then feed pipe 1 is flowed into by outlet pipe 28, low temperature warm water flows in energy-saving appliance 2 by feed pipe 1, low temperature warm water and the high-temperature tail gas in energy-saving appliance 2 internal flue carry out becoming high temperature warm water after heat exchanges, then flow into steam boiler inner chamber by outlet pipe 1 and heated rear generating steam further.Owing to first carrying out elementary heating by condenser 6, the warm water flowed into after again being heated by energy-saving appliance 2 again in steam boiler 1 has had higher temperature, steam can be boiled into, so more energy-conservation only the heat exchange of short period need be carried out in steam boiler 1 after.
When energy-saving appliance 2 only need be adopted, as long as close infusion pump 2 13, close stop valve 9 and conducting check valve 15, like this, cold water in softened water tank 5 is just direct to be flowed in energy-saving appliance 2 by feed pipe 1 through check valve 15, cold water and the high-temperature tail gas in energy-saving appliance 2 internal flue carry out becoming warm water after heat exchanges, and then flow into steam boiler inner chamber by outlet pipe 1 and are heated rear generating steam further.
