Description
Technical field
The present invention relates to a kind of garbage combustion device, is the high-temp. vortex primary dust removing device that the high-temperature flue gas after the waste incineration is carried out cyclone dust removal specifically, and it directly is connected with the smoke outlet of incinerator.
Background technology
At present, in the garbage disposal industry, a large amount of house refuses and industrial refuse all need to be transported to the garbage reclamation station and reclaim, and finally carry out burning disposal by incinerator.Owing to after rubbish burns in incinerator, can produce a large amount of high-temperature flue gas, and containing a large amount of harmful substance particles in this high-temperature flue gas, directly this high-temperature flue gas being discharged in the atmosphere and can causing severe contamination to environment.Therefore, the smoke outlet at incinerator all needs to arrange deduster.Deduster is connected in sequence from top to bottom by body of wall and the ash-collecting tube of cylindrical shell, taper barrel; The center position of the upper end closed end of cylindrical shell has perforate, is connected with central tube in the perforate, and the lower end of central tube is stretched in cylindrical shell; There is gas approach position at corresponding central tube on the sidewall of cylindrical shell.During use, the gas approach of this deduster directly is connected with the exhanst gas outlet of incinerator, like this, the annular channel that the high-temperature flue gas through producing after the incinerator burning forms between can entering by central tube, cylindrical shell through gas approach.In this annular channel, high-temperature flue gas is when carrying out circular motion along with annular channel, rear whereabouts wherein bumps between larger harmful substance particle and cylinder inboard wall, central tube outer wall, be rolled into ash-collecting tube behind the inner chamber inclined-plane via body of wall again and collect, finally discharge via the inner chamber of central tube through the high-temperature flue gas after the dedusting.
Traditional incinerator is to be made by refractory metal with the central tube of deduster, when high-temperature flue gas within it during flows outside, flue gas can produce friction with the barrel of central tube, heavy wear can appear in the long-term rear center's cylinder that uses, so that shorten the service life of central tube, cause the replacing of deduster, maintenance cost to increase.
Summary of the invention
The problem to be solved in the present invention provides a kind of high-temp. vortex primary dust removing device, adopts this deduster, and the service life of central tube is longer, can reduce replacing, maintenance cost.
For addressing the above problem, take following scheme:
High-temp. vortex primary dust removing device of the present invention comprises cylindrical shell, and it is made by exotic material.The openend of described cylindrical shell down, cylindrical shell upper end closed end center position has perforate, is sealedly connected with central tube in the perforate, the lower end of central tube is stretched in cylindrical shell.Described cylinder lateral wall has a gas approach in the position of corresponding central tube.The openend of described cylindrical shell below is connected with body of wall, and this body of wall is taper barrel, and its upper end open place diameter equates with described cartridge openings end internal diameter, and body of wall upper end open place diameter is greater than lower ending opening place diameter, and body of wall lower ending opening place is connected with ash-collecting tube.Described body of wall is piled up by refractory brick and is formed.Be characterized in that described central tube made by high temperature ceramic material.
The further improvement of the present invention scheme is that the center line of the annular channel that forms between the axis of described gas approach and central tube, cylindrical shell is tangent.Like this, after being conducive to flue gas and entering cylindrical shell, can flow along the annular channel that forms between central tube and cylindrical shell smoothly, reduce the friction between flue gas and central tube.
In the such scheme, be coated with housing in the outside of described cylindrical shell and body of wall, between described cylindrical shell and that piece housing corresponding with it, be filled with insulation material.All stretch out outside housing described central tube upper end, gas approach outer end.Like this, can prevent that the sidewall of the high temperature process cylindrical shell of flue gas is delivered to space outerpace, avoid the potential safety hazard that causes because environment temperature is too high.
Take such scheme, have the following advantages:
Because the central tube of high-temp. vortex primary dust removing device of the present invention adopts high temperature ceramic material to make, and the anti-wear performance of high temperature ceramic material will be better than refractory metal greatly, high-temperature flue gas is within it during flows outside, flue gas is relatively slight to the wearing and tearing that the central tube barrel causes, thereby so that greatly increase the service life of central tube, also reduced replacing, the maintenance cost of this deduster simultaneously.
Description of drawings
Fig. 1 is the structural representation of high-temp. vortex primary dust removing device of the present invention;
Fig. 2 is the cylindrical shell, central tube of high-temp. vortex primary dust removing device of the present invention and the schematic cross-section of the annular channel that gas approach forms.
The specific embodiment
As depicted in figs. 1 and 2, high-temp. vortex primary dust removing device of the present invention comprises cylindrical shell 2, and it is made by exotic material.The openend of described cylindrical shell 2 and is connected with body of wall 5 down.Body of wall 5 is taper barrel, its by refractory brick pile up form and.Body of wall 5 upper end open place diameters equate with described cylindrical shell 2 openend internal diameters, and body of wall 5 upper end open place diameters are greater than lower ending opening place diameter, and body of wall 5 lower ending opening places are connected with ash-collecting tube 6.The outside of described cylindrical shell 2 and body of wall 5 is coated with housing 4, is filled with insulation material 3 at described cylindrical shell 2 and 4 of that piece housings corresponding with it.The center position of cylindrical shell 2 upper end closed ends has perforate, is sealedly connected with central tube 1 in the perforate.Described central tube 1 is made by high temperature ceramic material, and its lower end is stretched in cylindrical shell 2, and central tube 1 is coaxial with cylindrical shell 2.Described cylindrical shell 2 sidewalls have a gas approach 7 in the position of corresponding central tube 1, the center line of the annular channel of the axis of gas approach 7 and central tube 1,2 formation of cylindrical shell is tangent.All stretch out outside housing described central tube 1 upper end, gas approach 9 outer ends.
During use, the gas approach 7 of high-temp. vortex primary dust removing device of the present invention is installed on the exhanst gas outlet of incinerator, the high-temperature flue gas that produces after the incinerator burning enters cylindrical shell 2 inner chambers of this deduster by gas approach 7, these high-temperature flue gas can flow along the annular channel of cylindrical shell 2 and 1 formation of central tube.High-temperature flue gas in flow process, its solid particle that contains can and cylindrical shell 2 inwalls, central tube 1 outer wall between bump, the particle after the collision will fall along cylindrical shell 2 inwalls, be collected into ash-collecting tube 6 behind body of wall 5 inclined-planes.In the situation that follow-up high-temperature flue gas constantly enters, can slowly sink through the high temperature purification flue gas after the dedusting, finally discharge this deduster along central tube 1 inner chamber.
