Description
Technical field
The utility model relates to a kind of boiler, is specifically related to a kind of gas fired-boiler.
Background technology
Boiler, in the process of burning, in order to make material burn more thoroughly, reduce discharge amount of pollution, can need to pass into oxygen-enriched air auxiliary combustion in boiler usually.Oxygen-enriched air containing a large amount of steam, needed first to carry out drying, boiler just can be made to burn completely as requested before entering boiler, and decreasing pollution thing discharges.
Containing higher heat in the gas of boiler emission, if reclaim this part of heat not in time, both wasted energy, and also caused environment near chimney bad, and there is pollutant in the tail gas of discharge.And meanwhile, the initial temperature of oxygen-enriched air is lower, preferably first carries out waste heat before entering boiler.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, proposes a kind of gas fired-boiler of energy recovery waste heat, can make full use of the heat in flue gas, makes material burning in boiler more thorough.
The technical solution of the utility model is achieved in that a kind of gas fired-boiler of energy recovery waste heat, comprise boiler, main air inlet pipe and smoke exhaust pipe, also comprise the auxiliary inlet manifold be connected with main air inlet pipe, auxiliary inlet manifold passes into after being connected with preheating device, cooling device successively in scrubbing pond, preheating device is also connected with smoke exhaust pipe, gas and water separator, cooling device is connected with water inlet pipe and outlet pipe, water inlet pipe is provided with water pump.
Described gas and water separator comprises tank body, tank body is connected with air inlet pipe, blast pipe and drain pipe, dividing plate is provided with in tank body, tank body is divided into left cavity and right cavity by dividing plate, dividing plate is provided with the via hole being communicated with left cavity and right cavity, baffle plate under left cavity inner wall is provided with and is tilted to, is provided with packing layer in right cavity.
The high-temperature gas that boiler is discharged by the utility model passes in preheating device and cooling device successively, oxygen-enriched air is preheated, the waste heat of flue gas also exchanges with cold water simultaneously, the heat of flue gas can be made full use of, final flue gas passes in scrubbing pond, has taken out most objectionable impurities and dust etc. in tail gas.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of gas and water separator.
Wherein: 1. boiler, 2. main air inlet pipe, 3. auxiliary inlet manifold, 4. smoke exhaust pipe, 5. preheating device, 6. gas and water separator, 6-1. air inlet pipe, 6-2. blast pipe, 6-3. drain pipe, 6-4. via hole, 6-5. packing layer, 6-6. tank body, 6-7. dividing plate, the left cavity of 6-8., the right cavity of 6-9., 6-10. baffle plate, 7. water inlet pipe, 8. outlet pipe, 9. cooling device, 10. scrubbing pond, 11. water pumps.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of gas fired-boiler of energy recovery waste heat, comprise boiler 1, main air inlet pipe 2 and smoke exhaust pipe 4, also comprise the auxiliary inlet manifold 3 be connected with main air inlet pipe 2, auxiliary inlet manifold 3 passes into after being connected with preheating device 5, cooling device 9 successively in scrubbing pond 10, preheating device 5 is also connected with smoke exhaust pipe 4, gas and water separator 6, and cooling device 9 is connected with water inlet pipe 7 and outlet pipe 8, water inlet pipe 7 is provided with water pump 11.
Utility model works principle is as follows: gas and water separator 6 is by the gas-water separation in oxygen rich gas, dry gas enters preheating device 5, simultaneously in smoke exhaust pipe 4, high-temperature gas out enters cooling device again after preheating device 5, flue gas carries out heat exchange with oxygen-enriched air in preheating device 5, boiler auxiliary combustion is entered by auxiliary inlet manifold 3 after oxygen-enriched air is heated, and the flue gas after cooling enters cooling device 9 and cooling water carries out heat exchange again, water after heating is separately used as him, and the gas after reducing temperature twice enters scrubbing pond 10, react with the liquid in scrubbing pond 10, most dust, the gases such as carbon dioxide and liquid react, the gas of finally discharging from scrubbing pond reaches discharge standard.
In this process, high-temperature flue gas is lowered the temperature, and oxygen-enriched air just sends into boiler after being heated, and is conducive to the burning of material in boiler, takes full advantage of the heat of high-temperature tail gas, and improves the surrounding enviroment of boiler.
As shown in Figure 2, described gas and water separator 6 comprises tank body 6-6, tank body 6-6 is connected with air inlet pipe 6-1, blast pipe 6-2 and drain pipe 6-3, dividing plate 6-7 is provided with in tank body 6-6, tank body 6-6 is divided into left cavity 6-8 and right cavity 6-9 by dividing plate 6-7, dividing plate 6-7 is provided with the via hole 6-4 being communicated with left cavity 6-8 and right cavity 6-9, and left cavity 6-8 inwall is provided with the baffle plate 6-10 under being tilted to, and is provided with packing layer 6-5 in right cavity 6-9.
In gas and water separator 6, air inlet pipe 6-1 is arranged on tank body 6-6 bottom, oxygen-enriched air enters in left cavity 6-8 by air inlet pipe 6-1, baffle plate 6-10 choked flow is run in the process upwards run, baffle plate 6-10 is rough and uneven in surface, part steam first condenses on baffle plate 6-10, fall bottom tank body 6-6 again, gas through preliminarily dried enters right cavity 6-9 by via hole 6-4 again, when gas through packing layer 6-5 time, by again dry, dried gas eventually passes through blast pipe 6-2 and enters boiler auxiliary combustion.The drain pipe 6-3 of liquid then through bottom discharges.In the utility model, mist through first tentatively dewatering through baffle plate, then filters out moisture through packing layer.Oxygen-enriched air in gas and water separator 6 is through double-filtration, and water content drops to minimum, and the rate of filtration is very fast, can meet boiler combustion needs.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
