Utility model content
The purpose of this utility model is for the above-mentioned problems in the prior art, provide one utilize waste heat to heat up water after can water storage, and the flue gas waste heat recovery apparatus of the band water storage function that can also be incubated.
The purpose of this utility model realizes by following technical proposal: a kind of flue gas waste heat recovery apparatus with water storage function, comprise housing, case top and bottom are respectively equipped with gas outlet and air inlet, it is characterized in that: in described housing, be respectively equipped with independently heating water tank and attemperater, described attemperater is coated on outside heating water tank, described heating water tank is provided with water inlet pipe one and outlet pipe one, described attemperater is provided with water inlet pipe two and outlet pipe two, described outlet pipe one is communicated with water inlet pipe two, also comprise some hollow heat exchanger tubes, described heat exchanger tube is each passed through heating water tank and attemperater, and heat exchanger tube two ends are communicated with gas outlet with air inlet respectively, the part that described heat exchanger tube stretches into heating water tank is spiral tubular structure.
Air inlet passes into flue gas, and flue gas enters in heat exchanger tube, is contacted the flue gas heat utilized in heat exchanger tube by heat exchanger tube with heating water tank, and final flue gas is discharged from gas outlet; Owing to also there is attemperater, and outlet pipe one is communicated with water inlet pipe two, therefore can flow in attemperater after hot water heating and be incubated, and a part of heat exchanger tube is through attemperater, attemperater is made to have certain insulating power, and attemperater is coated on outside heating water tank and makes attemperater insulating power strengthen, and the heating water tank efficiency of heating surface is higher, and the heat exchanger tube in addition in heating water tank adopts spiral tubular structure also can improve heat utilization efficiency.
Above-mentioned a kind of with in the flue gas waste heat recovery apparatus of water storage function, between described heating water tank and attemperater, there is interstitial spaces.
Arranging interstitial spaces avoids heating water tank and attemperater to influence each other.
Above-mentioned a kind of with in the flue gas waste heat recovery apparatus of water storage function, described gas outlet is also provided with filter screen.
A part of deleterious particle, more environmental protection in strainer filtering flue gas are set.
Above-mentioned a kind of with in the flue gas waste heat recovery apparatus of water storage function, described outlet pipe one is provided with magnetic valve.
Magnetic valve is set and facilitates external control.
Compared with prior art, the utility model tool has the following advantages:
Air inlet passes into flue gas, and flue gas enters in heat exchanger tube, is contacted the flue gas heat utilized in heat exchanger tube by heat exchanger tube with heating water tank, and final flue gas is discharged from gas outlet; Owing to also there is attemperater, and outlet pipe one is communicated with water inlet pipe two, therefore can flow in attemperater after hot water heating and be incubated, and a part of heat exchanger tube is through attemperater, attemperater is made to have certain insulating power, and attemperater is coated on outside heating water tank and makes attemperater insulating power strengthen, and the heating water tank efficiency of heating surface is higher, and the heat exchanger tube in addition in heating water tank adopts spiral tubular structure also can improve heat utilization efficiency.
