Abstract
The utility model discloses a disconnect -type heat transfer combustor to reduce the environmental pollution that the working process probably brought. Including the combustion chamber, be equipped with the outer tube and the inner tube that paste mutually on the lateral wall of combustion chamber, the position of inner tube is between combustion chamber and outer tube, and the hookup of inner tube entrance point has air intlet, the exit end of inner tube and the entry end of outer tube intercommunication, the exit end hookup of outer tube has the air outlet, is equipped with the helical shape guide vanes who is used for adding vast sky air flow path footpath in inner tube and the outer tube, and the exit end of combustion chamber has solid export intercommunication to the combustion chamber of gas -solid separator, gas -solid separator through the pipeline hookup. Handle the ejected matter of combustion chamber through the gas -solid separator, the solid isolated fully burns in sending into the combustion chamber again to guarantee as far as that the solid combustible substance in the equipment obtains comprehensive utilization, has also avoided these solid particle things to discharge simultaneously and has caused environmental pollution.
Description
Technical field
This utility model relates to a kind of separate type recuperator burner.
Background technology
Heat exchange type burner has two kinds of basic structure forms, is separate type recuperator burner and self-preheating type recuperator burner respectively.Separate type made by heat exchanger and burner by separate type recuperator burner, and self-preheating type recuperator burner is heat exchanger and burner to be made of one, also referred to as integral type recuperator burner.Separate type is easy to heat exchanger and burner overhauls respectively and changes.Self-preheating type compact conformation, it is easily installed.
Separate type recuperator burner is advanced along flue gas and is divided radiation and a convection current two sections.At convection section, flue gas leans on the negative pressure jet flow surface to heat exchanger tube of smoke evacuation system, and is passed to heat around the cold air flowing through this outside by barrel.Radiant section air duct at heat exchanger is connected double-deck crack, air initially enters interior crack by spin chamber, owing to flow rotation enhances the heat exchange between air and metal barrel, air is heated and proceed to that then outer layer is sensible is collected for hot blast gas burner by outlet ring casing in advancing.If the fuel combustion that recuperator burner is in a combustion chamber is not thorough, the unburnt solid particle in combustor is also easily sent by the flowing of flue gas simultaneously, on the one hand reduces efficiency of combustion, has on the other hand also increased the weight of the pollution to environment.
Utility model content
This utility model is intended to provide a kind of separate type recuperator burner, to reduce the environmental pollution that work process may be brought.
Separate type recuperator burner in this programme, including combustor, the sidewall of combustor is provided with the outer tube and inner tube being affixed, the position of inner tube is between combustor and outer tube, inner tube entrance point couples air intlet, the port of export of inner tube connects with the arrival end of outer tube, the port of export of outer tube couples air outlet slit, inner and outer tubes are provided with the spiral guide vane for lengthening air flow path footpath, the port of export of combustor is coupled by pipeline gas-solid separator, and the solid outlet of gas-solid separator is communicated to combustor.
The feature of technique scheme is: processed by gas-solid separator by the ejected matter of combustor, isolated solid is sent to fully burn in combustor again, comprehensively utilized with the solid combustible in guarantee equipment as far as possible, it also avoid the discharge of these solid particulate matters simultaneously and cause environmental pollution.The air entered in equipment arrives outer tube by inner tube, realize sufficient heat exchange in this process, and in inner and outer tubes, it is additionally provided with spiral guide vane, long air can be added in inner and outer tubes, pass through path, simultaneously also increase the air overall time at heat exchanging process so that heat exchange better.
Further, inner and outer tubes are enclosed in the sidewall of combustor the most successively.Contact area therebetween, raising heat exchanging efficiency can be strengthened.
Further, the lateral wall of outer tube is provided with thermal insulation layer.To stop heat to transmit so that causing waste to outside.
Further, gas-solid separator is cyclone separator.Its technology maturation, combination property is preferable.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: combustor 1, air intake 2, inner tube 3, outer tube 4, air outlet slit 5, cyclone separator 6, backpass ductwork 7, guide vane 8.
Embodiment is the most as shown in Figure 1: in this device, combustor 1 is that vertical direction is arranged, fuel constantly burns in combustor 1 and produces heat, the sidewall of combustor 1 surrounding is provided with ring-type inner tube 3, the inwall of inner tube 3 and combustor 1 share one layer of wall, the outer wall of inner tube 3 shares one layer of wall with the inwall of annular outer tube 4, the outer wall of outer tube 4 is provided with thermal insulation layer, and the main material of thermal insulation layer is rock wool.The arrival end on inner tube 3 top is provided with air intake 2, inner tube 3 connects with the bottom of outer tube 4, the port of export on outer tube 4 top is provided with air outlet slit 5, inner tube 3 and outer tube 4 are welded with spiral guide vane 8, guide vane 8 makes the air in inner tube 3 and outer tube 4 advance in a helical pattern, extends the circulation path of air.
The gas produced in combustor 1 is discharged by the outlet on its top, and it is switched to a cyclone separator 6, the effect of cyclone separator 6 is the separation that the material of input carries out solid and gas, gas is discharged by top, other air-treatment operation can be sent to, the isolated solid of cyclone separator 6 is linked into the bottom of combustor 1 by backpass ductwork 7 below, this structure does not interferes with the normal combustion work of combustor 1, can be by setting up valve at the end of backpass ductwork 7, needs when, just open valve, described valve can be closed at ordinary times.
Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and/or characteristic too much describes at this.Should be understood that; for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
