Abstract
The utility model relates to the boiler surplus-heat recycling technical field, and particularly relates to a smoke gas surplus-heat recycling device, which comprises a thermotube air pre-heater which is installed on a flue on the tail part of a boiler, and is characterized in that: a tube pass outlet of the thermotube air pre-heater is connected with an inlet of a draft fan through a pipeline, an outlet of the draft fan is connected with a gas inlet of a drying bed through a pipeline, and a shell pass outlet of the thermotube air pre-heater is provided with an electrostatic dust collector. A pulse-type ash blower is installed on a shell pass gas inlet end of the thermotube air pre-heater. By utilizing high-efficient thermotube heat exchanging technology, the surplus heat of the smoke gas is recycled to use, so not only is the operation performance of the boiler free from influencing, but also the recycling of the waste heat can be realized; and at the same time, the temperature of the discharged smoke gas can be reduced, and the atmosphere pollution can be reduced.
Description
Technical field
The utility model relates to boiler afterheat recovery technology field, specifically a kind of flue gas waste heat recovery apparatus.
Background technology
The exhaust gas temperature of at present general station boiler design is about 150 ℃, and the flue gas that contains certain calorific value is in a large number arranged to atmosphere by chimney without utilizing directly, not only increases environmental pollution, and causes energy waste.Existing flue gas retracting device is a lot, and their structure is generally very complicated, therefore invents a kind of flue gas waste heat recovery apparatus simple in structure and is highly profitable.
Summary of the invention
Technical problem to be solved in the utility model is exactly the defective at existing station boiler, a kind of flue gas waste heat recovery apparatus is provided, it utilizes high efficiency heat pipe heat exchanging technology, flue gas waste heat recovery is utilized again, neither influence the boiler operatiopn performance, reach the purpose of Waste Heat Recovery again, reduce exhaust gas temperature simultaneously, reduce atmosphere pollution.
The technical solution of the utility model is achieved in that it comprises the heat-pipe air preheater that is installed on the boiler back end ductwork, it is characterized in that: the tube side outlet of heat-pipe air preheater is connected with the import of air-introduced machine by pipeline, the outlet of air-introduced machine is connected with the air inlet of drying bed by pipeline, and electrostatic precipitator is equipped with in the shell side outlet of heat-pipe air preheater.Gas approach end at the shell side of heat-pipe air preheater is equipped with the pulsed soot blower.
The utlity model has following advantage:
1, compact conformation, the heat transfer efficiency height, the fluid resistance is decreased little.
2, easy to operate, the controllability height is by regulating air capacity, the temperature of regulating preheated air.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model is installed in the heat-pipe air preheater 1 on the boiler back end ductwork, the tube side outlet of heat-pipe air preheater 1 is connected by the import of pipeline with air-introduced machine 2, the outlet of air-introduced machine 2 is connected by the air inlet of pipeline with drying bed 3, and electrostatic precipitator 5 is equipped with in the shell side outlet of heat-pipe air preheater.Gas approach end at the shell side of heat-pipe air preheater is equipped with pulsed soot blower 4.
Its operation principle is: the waste heat flue gas that boiler is discharged, and row is to atmosphere (the cigarette temperature descends 45 ℃) after heat pipe air preheater 1 heat exchange cooling; Normal temperature air is after the heat pipe air preheater heating, and temperature rises 70 ℃, delivers to next stage heat exchanger (drying bed 3) through air-introduced machine 2, in order to the bake drying other products; Time opening pulse soot blower 4 purges heat pipe air preheater tubulation superficial dust, guarantees the good heat transfer effect; Regulate the air quantity of air-introduced machine 2, the air themperature after the control preheating.
