Abstract
The utility model discloses a multi-hearth-furnace sludge incineration device with a secondary combustor. The multi-hearth-furnace sludge incineration device mainly comprises a dewatered sludge bin, a feedstock conveyor, a preheating mixer, an air blower, a multi-hearth incineration furnace, an auxiliary fuel burner, a Venturi separator, a washer, an electrostatic dust collector, a regenerative exchanger, and the secondary combustor. The multi-hearth-furnace sludge incineration device is characterized in that an outlet in the side surface at the top end of the multi-hearth incineration furnace is sequentially connected with the Venturi separator, the washer, the electrostatic dust collector and the regenerative exchanger through a pipeline, and a ceramic filer is arranged in the regenerative exchanger. The multi-hearth incineration furnace incinerates the sludge, the secondary combustor is arranged to reduce the exhaust emission, and the regenerative exchanger is used for recovering part of the heat.
Description
Technical field
The utility model relates to a kind of multiple hearth furnace sludge incineration device with secondary combustion chamber.
Background technology
The discharge capacity of urban industry waste water and sanitary sewage is increasing, and treatment rate of domestic sewage also improves year by year, and the sludge yield of municipal sewage plant also sharply increases.A large amount of excess sludges will discharge in sewage treatment plant, and the mud of enormous amount need to be done further processing, if mud can not get reasonable processing, will cause secondary pollution.The processing disposal costs of sewage sludge is higher, in whole construction costs of sewage treatment plant, for the treatment of mud, accounts for 20%～50%.Because sludge quantity is larger, mummification need to be compared with multiple-energy-source, and landfill is wasted again land resource, and mud self has certain calorific value, therefore can burn the disposal that realizes mud.
Utility model content
The purpose of this utility model is to provide a kind of multiple hearth furnace sludge incineration device with secondary combustion chamber, adopts many thoraxes incinerator that mud is burned, and secondary combustion chamber is set and reduces toxic emission, adopts heat regenerator recovery section heat.
The purpose of this utility model is achieved through the following technical solutions: a kind of multiple hearth furnace sludge incineration device with secondary combustion chamber, mainly by dewatered sludge storehouse, feeding conveyor, preheating mixer, air blast, many thoraxes incinerator, auxiliary fuel burners, venturi separator, washer, electrostatic precipitator, heat regenerator and two stage burner, formed, it is characterized in that: the top side exit of described many thoraxes incinerator is connected with venturi separator, washer, electrostatic precipitator and heat regenerator successively by pipeline; In described heat regenerator, be provided with ceramic packing.
Between described washer and electrostatic precipitator, be provided with air-introduced machine.
The top of described heat regenerator is provided with two stage burner, and the outlet of two stage burner is connected with the top of many thoraxes incinerator by pipeline.
In sum, the beneficial effects of the utility model are: adopt many thoraxes incinerator that mud is burned, at the charging aperture of many thoraxes incinerator, be provided with preheating mixer, secondary combustion chamber is set and reduces toxic emission, adopt heat regenerator recovery section heat, realize recuperation of heat; There is perfect waste gas pollution control and treatment system, prevent from causing air pollution.
Accompanying drawing explanation
Fig. 1 system schematic of the present utility model.
The title of mark in accompanying drawing: 1-dewatered sludge storehouse; 2-feeding conveyor; 3-preheating mixer; 4-air blast; 5-many thoraxes incinerator; 6-ash discharging hole; 7-auxiliary fuel burners; 8-venturi separator; 9-washer; 10-electrostatic precipitator; 11-ceramic packing; 12-heat regenerator; 13-two stage burner.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment: as shown in Figure 1, the utility model is mainly by dewatered sludge storehouse (1), feeding conveyor (2), preheating mixer (3), air blast (4), many thoraxes incinerator (5), auxiliary fuel burners (7), venturi separator (8), washer (9), electrostatic precipitator (10), heat regenerator (12) and two stage burner (13) form, it is characterized in that: the top side exit of described many thoraxes incinerator (5) by pipeline successively with venturi separator (8), washer (9), electrostatic precipitator (10) and heat regenerator (12) connect, in described heat regenerator (12), be provided with ceramic packing (11).
Between described washer (9) and electrostatic precipitator (10), be provided with air-introduced machine.
The top of described heat regenerator (12) is provided with two stage burner (13), and the outlet of two stage burner (13) is connected with the top of many thoraxes incinerator (5) by pipeline.
Operation principle of the present utility model: the mud of sewage treatment plant carries out after thickening, moisture content is that 80～85% mud enters dewatered sludge storehouse (1), feeding conveyor (2) arrives preheating mixer (3) by sludge lifting, after mixing, enter mud burns in many thoraxes incinerator (5), mud has certain calorific value, auxiliary fuel burners during startup (7) provides combustion gas for many thoraxes incinerator (5), light mud, then need less combustion gas, mud can maintain burning, lime-ash is discharged from ash discharging hole (6), waste gas is discharged from many thoraxes incinerator (5) side, top, through venturi separator (8), washer (9), electrostatic precipitator (10) is processed waste gas, then enter in heat regenerator (12), waste gas burns and removes pollutant in two stage burner (13), part waste gas circulation is returned many thoraxes incinerator (5), reduce the discharge of waste gas, effectively utilize heat simultaneously.
As mentioned above, just can realize preferably the utility model.
