Description
Technical field
The utility model belongs to industrial waste gas technical field of waste heat utilization, is specifically related to a kind of flue gas waste heat utilization device.
Background technology
The various Pump for Medium and Small Power Generating Set (as gas electricity generator) of domestic smoke evacuation use extensively, and flue gas, if not being used, can take away a large amount of heats.Utilize waste heat boiler by water circulation at present, heat is brought into hot-tub, output hot water.Use above-mentioned traditional UTILIZATION OF VESIDUAL HEAT IN way, water is in the easy fouling of high temperature, if water quality inferiority, fouling is serious, easily blocks reimbursement heat transmission equipment.If carry out softening existence again two shortcomings to water: cost is high, and institute's heat production water remains softening agent.
Summary of the invention
The purpose of this utility model overcomes above-mentioned deficiency, provides one without water as delivered heat working medium, the flue gas waste heat utilization device of transporting flue gas heat exchange water.
The utility model solves the technical scheme that its technical problem adopts: a kind of flue gas waste heat utilization device, comprise unit 1, flue gas house steward 2, pond 3, heat exchanger tube 4, axial flow blower 5, smoke exhaust pipe 6 and emergent exhaust stack 7, it is characterized in that, the tail gas manifold of each unit 1 is guided on a flue gas house steward 2, flue gas house steward 2 extends in pond 3, the other end of flue gas house steward 2 is connected with heat exchanger tube 4, flue gas house steward 2 is provided with emergent exhaust stack 7, heat exchanger tube 4 passes pond 3 spindle flow fan 5 again, axial flow blower 5 provides power for whole system gas, so that unit 1 is vented, axial flow blower 5 runs in smoke pipe 6.
Described heat exchanger tube 4 adopts the stainless steel seamless pipe measure-alike with flue gas house steward 2, and interpolation fin 10 increases interior heat exchange area, and outside weldings filled circles steel bar 11 increases external heat-exchanging area.
UTILIZATION OF VESIDUAL HEAT IN object flue gas is high temperature refrigerant, and as gas electricity generator, exhaust gas temperature is 450 ~ 600 DEG C, therefore requires the pipeline of transmission flue gas high temperature resistant and insulation.The utility model adopts on-the-spot foam cement pipe processed, includes reinforcing bar, and cast considers that easy construction can be square tube.Foam cement is conventional heat insulating material formed in civil engineering, adds blowing agent, hydrogen peroxide is made by cement.Foam cement is rich in tiny cavity, forms thermal contact resistance, reduces thermal conductivity factor and have heat insulating function.Compare the thermal conductivity factor 45W/mK of carbon steel, the thermal conductivity factor of this kind of material can at below 5W/mK.Ordinary cement is non-refractory, needs to select high-temp .-resistant slag cement, high temperature resistant graphite cement etc.Add quartz sand, add aluminate and can improve cement high temperature resistant property.Add the quartz sand of porphyrize, as add in G class g cement quartz sand content up to 30% time, high temperature resistance can reach 328 DEG C.When adding tricalcium aluminate in cement, high temperature resistant property is greatly strengthened, and when tricalcium aluminate content reaches 30%, high temperature resistance can reach 500 DEG C.
The beneficial effects of the utility model are: non flouling behaviour in heat exchange tube, and the outside fouling of pipe is convenient to soak scale remover and is scrubbed; Flue gas heat conduction and water heat exchange, the hot water temperature produced is higher; Save boiler, water circulating pump facility has dropped into; Decrease the heat loss of boiler pipeline section.
Below in conjunction with drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
See Fig. 1 and Fig. 2, a kind of flue gas waste heat utilization device that the utility model proposes, comprise unit 1, flue gas house steward 2, pond 3, heat exchanger tube 4, axial flow blower 5, smoke exhaust pipe 6 and emergent exhaust stack 7, it is characterized in that, the tail gas manifold of each unit 1 is guided on a flue gas house steward 2, flue gas house steward 2 extends in pond 3, the other end of flue gas house steward 2 is connected with heat exchanger tube 4, flue gas house steward 2 is provided with emergent exhaust stack 7, heat exchanger tube 4 passes pond 3 spindle flow fan 5 again, axial flow blower 5 provides power for whole system gas, so that unit 1 is vented, axial flow blower 5 runs in smoke pipe 6.
Described heat exchanger tube 4 adopts the stainless steel seamless pipe measure-alike with flue gas house steward 2, and interpolation fin 10 increases interior heat exchange area, and outside weldings filled circles steel bar 11 increases external heat-exchanging area.
The offgas duct of each unit 1 is connected the long-pending foam cement pipe of same cross-sectional, and be pooled on a flue gas house steward 2, flue gas house steward 2 vertically declines from basin inlet 8 and extends to 3 li, pond, and bottom pond 3, connect heat exchanger tube 4, heat exchanger tube 4 is gapless stainless steel tube; Heat exchanger tube 4 is erected on heat exchange tube support 9, and level is moved towards, the built-in fin 10 of this part heat exchanger tube 4, outside weldings filled circles steel bar 11.
After heat exchanger tube 4 discharge bay 3, spindle flow fan 5, blower fan band flow-speed measurement, FEEDBACK CONTROL, ensures the circulation of whole piece tunnel gas.
In system maintenance or when running into fault, open the valve on emergent exhaust stack 7, smoke discharging.
