Description
Technical field
The utility model relates to a kind of garbage combustion device, be the high-temp. vortex secondary ash collector that carries out cyclone dust removal to after the waste incineration and through the high-temperature flue gas of primary dust removing specifically, its gas approach is connected with the smoke outlet of the primary dust removing device 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 contain a large amount of harmful substance particles in this high-temperature flue gas, directly this high-temperature flue gas is discharged in the atmosphere and can cause 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; A gas approach is arranged in the position of 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.
Only be provided with the primary dust removing device in traditional garbage combustion device, and a gas approach is only arranged on the cylinder lateral wall of deduster, during annular channel in high-temperature flue gas enters cylindrical shell, its flow velocity is slower.Therefore, collision between the harmful substance particle in the high-temperature flue gas and cylinder inboard wall, central tube outer wall is comparatively slight, clearance of particles that only can part is larger, and so that also contain a large amount of trickle harmful substance particles in the high-temperature flue gas after the deduster dedusting, enter that appoint in the air so can be to environment.
The utility model content
Problem to be solved in the utility model provides a kind of high-temp. vortex secondary ash collector, two gas approach of this secondary ash collector can be connected with the exhanst gas outlet of two primary dust removing devices simultaneously, thereby increase the flue gas flow rate that enters this secondary ash collector inner chamber, further remove the trickle harmful substance particle in the high-temperature flue gas, can effectively reduce the flue gas pollution on the environment of discharge.
For addressing the above problem, take following scheme:
High-temp. vortex secondary ash collector of the present utility model 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.The openend below of described cylindrical shell is connected with body of wall, and this body of wall is taper barrel, and its upper end open place diameter equates that with described cartridge openings end internal diameter 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 respectively there is a gas approach at the radially relative position place of described cylindrical shell on that section sidewall of corresponding central tube.
The further improvement of the utility model scheme is that described central tube is made by high temperature ceramic material.The wearability of ceramic material is better, can increase the service life of central tube, reduces maintenance, replacement cost.
The further improvement of the utility model scheme be described gas approach axis all and the center line of the annular channel that forms between central tube, cylindrical shell 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 respectively there is a gas approach at the radially relative position place of cylindrical shell on that section sidewall of corresponding central tube of high-temp. vortex secondary ash collector of the present utility model, be that two gas approach are arranged on the cylindrical shell, during use, these two gas approach are connected with the exhanst gas outlet of two primary dust removing devices respectively, in the situation that the bore of the gas approach of the exhanst gas outlet of primary dust removing device and this secondary ash collector all equates, but Effective Raise enters the flue gas flow rate of this secondary ash collector inner chamber, harmful substance particle and cylinder inboard wall in the high-temperature flue gas have been aggravated, collision between the central tube outer wall, so that trickle harmful substance particle wherein also can fall to ash-collecting tube after collision, further removed the trickle harmful substance particle in the high-temperature flue gas, thereby so that the content of harmful substance is less in the high-temperature flue gas after this secondary ash collector dedusting, can effectively reduce pollution on the environment.
