At present, a heat exchange structure for a flue gas waste heat recovery device, which is simple in structure, reasonable in design and high in flue gas waste heat recovery rate, does not exist. The heat exchange structure is characterized by comprising a water-storage heat-exchange tank, a flue gas inlet pipe, a flue gas outlet pipe, a water inlet pipe, a water outlet pipe and a plurality of heat exchange pipes, the heat exchange pipes are mounted in the water-storage heat-exchange tank and are parallel to one another, the flue gas inlet pipe and the flue gas outlet pipe are fixed at two ends of the water-storage heat-exchange tank respectively and are communicated with two ends of the heat exchange pipes respectively, and the water inlet pipe and the water outlet pipe are fixed at the top and at the bottom of the water-storage heat-exchange tank respectively. The heat exchange structure is reasonable in structural design, high in flue gas waste heat recovery rate and beneficial to energy saving and environmental protection.
Description
Technical field
The utility model relates to a kind of heat exchange structure, especially relate to a kind of heat exchange structure for device for recovering excess heat of flue gas, belong to parts in the device for recovering excess heat of flue gas, device for recovering excess heat of flue gas is mainly used in the heat in the flue gas that recovery boiler discharges.
Background technology
At present, the use of boiler in factory is comparatively general, and boiler contains higher waste heat in the flue gas that produces when operation, generally, the temperature of the flue gas of discharging from boiler is at 220 degrees centigrade, and the flue gas that boiler produces directly enters in the atmosphere, and the waste heat that causes flue gas to be carried also directly is drained in the atmosphere, not only caused air pollution, be unfavorable for environmental protection, and reduced the utilization rate of the energy, be unfavorable for energy-conservation.Also do not have now a kind of simple in structurely, reasonable in design, the waste heat recovery rate of flue gas is high, is conducive to the heat exchange structure that is used for device for recovering excess heat of flue gas of energy-conserving and environment-protective.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and the waste heat recovery rate of flue gas is high, is conducive to the heat exchange structure that is used for device for recovering excess heat of flue gas of energy-conserving and environment-protective.
The technical scheme in the invention for solving the above technical problem is: the design feature that should be used for the heat exchange structure of device for recovering excess heat of flue gas is: comprise the water storage heat exchange tank, advance fume pipe, the smoke evacuation tracheae, water inlet pipe, outlet pipe and several heat-exchange tube, described several heat-exchange tube is installed in the water storage heat exchange tank, be parallel to each other between these several heat-exchange tubes, describedly enter the two ends that fume pipe and smoke evacuation tracheae are separately fixed at the water storage heat exchange tank, this advances fume pipe and the smoke evacuation tracheae is connected with the two ends of heat-exchange tube respectively, and described water inlet pipe and outlet pipe are separately fixed at top and the bottom of water storage heat exchange tank.
As preferably, the quantity of heat-exchange tube described in the utility model is between the 10-50 root.
As preferably, the horizontal structure of heat-exchange tube described in the utility model.
The utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, the waste heat recovery rate of flue gas is high, and the flue gas of discharging from boiler needs the water of heating to pass through successively water inlet pipe, water storage heat exchange tank and outlet pipe successively through advancing fume pipe, heat-exchange tube and smoke evacuation tracheae, flue gas and the water that needs to heat carry out exchange heat by heat-exchange tube, so that water temperature raises, the temperature of flue gas reduces, thereby reaches the purpose of recovery waste heat.
Description of drawings
Fig. 1 is the main TV structure schematic diagram that is used for the heat exchange structure of device for recovering excess heat of flue gas among the utility model embodiment.
Fig. 2 is the sectional structure schematic diagram of A-A face among Fig. 1.
Fig. 3 is the structural representation that indicates among Fig. 1 into water, water outlet, flue gas and smoke outlet flue gas direction.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 3, the heat exchange structure that is used for device for recovering excess heat of flue gas in the present embodiment comprises water storage heat exchange tank 1, several heat-exchange tube 2, advances fume pipe 3, smoke evacuation tracheae 4, water inlet pipe 5 and outlet pipe 6, wherein, the quantity of heat-exchange tube 2 can arrange according to actual needs, generally, the quantity of this heat-exchange tube 2 is between the 10-50 root.
Several heat-exchange tubes 2 in the present embodiment are installed in the water storage heat exchange tank 1, are parallel to each other between these several heat-exchange tubes 2, and the heat-exchange tube 2 in the present embodiment is horizontal structure all.
Enter the two ends that fume pipe 3 and smoke evacuation tracheae 4 are separately fixed at water storage heat exchange tank 1 in the present embodiment, this advances fume pipe 3 and smoke evacuation tracheae 4 is connected with the two ends of heat-exchange tube 2 respectively, when flue gas after advance fume pipe 3 and enter, flow along heat-exchange tube 2 again, discharge from smoke evacuation tracheae 4 at last, so that the efficient of heat exchange is higher.
The heat exchange structure that is used for device for recovering excess heat of flue gas in the present embodiment belongs to parts in the device for recovering excess heat of flue gas, this heat exchange structure is high to the waste heat recovery efficient of flue gas, be conducive to energy-conserving and environment-protective, generally, the water temperature at water inlet pipe place is about 15 degrees centigrade, the water temperature at outlet pipe place is about 95 degrees centigrade, is about 220 ℃ and be positioned at into the temperature of the flue gas at fume pipe place, and the temperature that is positioned at the flue gas at smoke evacuation tracheae place is about 100 ℃.
In addition, need to prove, the specific embodiment described in this specification, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this specification only is to the explanation of the utility model structure example.Allly conceive equivalence variation or the simple change that described structure, feature and principle are done according to the utility model patent, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
