Abstract

PURPOSE:To carry out incineration treatment economically by providing the stern of a mother boat with a recessed section to which a dust storage tank of a tug boat which can sail by a pusher boat or by self propelling is removably connected and a dust supply device which supplies the dusts in the storage tank on the tug boat to an incinerator continuously. CONSTITUTION:Dusts that are brought in by a dust collecting and transporting vehicle are charged into a dust storage tank 8 of a tug boat 6 that is moored to a pier and waiting for dust loading. When a specified amount of dusts is stored the tug boat 6 is sailed by a pusher boat 5, and it is inserted into and connected to the recess section 7 that is formed in the stern of a mother boat A which is waiting offshore. The dusts in the storage tank 8 which is thus inserted and connected are scooped up successively by the bucket 25 of a crane 26 and they are charged into a dust charging hopper 27. The dusts in the dust charging hopper 27 are crushed by a crushing machine 28 and at the same time the crushed dusts continuously fall down into a crushed dust supply machine 27. Part of roughly crushed dusts are stored there and the rest are continuously supplied to an incinerator 9 of fluidized bed type. With this arrangement it is possible to treat dust by incineration economically.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is directed to a garbage incineration ship that incinerates household waste and other garbage on the sea.

[Prior art and its issues] In general, household waste and other garbage discharged from households are
Garbage collection and transportation vehicles collect the waste at designated locations and incinerate it at onshore incineration plants. Incineration of waste in such land-based factories has the following problems.

(a) There is an economic issue in that the cost of acquiring land for constructing a waste incineration plant is extremely high, and the cost of building the plant increases.

(b) When constructing a factory, it is difficult to preserve the local environment and harmonize with local residents, and in addition, as the population increases, it takes a lot of time to construct a factory.

(C) Maintenance costs are high.

(d) Procedures associated with factory construction and investment in related facilities are more difficult than necessary.

(e) In principle, since it is directly managed by local governments such as municipalities, an increase in the number of personnel is required, increasing fixed personnel costs.
There is an economic issue where public finances are under pressure.

(f) If the collected garbage overflows into the bit, there will be problems in dealing with it if there is no temporary storage space.

(g) Since electricity and fuel are used together, the cost is relatively high.

(h) When a large number of vehicles are brought in, the operation rotation of the vehicles becomes poor and the collection efficiency decreases.

The object of the present invention is to provide a garbage incinerator that can reasonably solve the problems of conventional land-based facilities by transporting garbage to a mother ship waiting at sea and incinerating all the garbage at sea. Our goal is to provide the following.

The mother ship A is generally configured as described above.

Next, the configuration of the waste incineration facility FwB will be described. 9 is a fluidized bed type combustion furnace, and the combustion exhaust gas of the combustion furnace 9 is supplied to a gas cooling chamber 10. The air is discharged into the atmosphere from a chimney 13 via an air preheater 11 and an electric precipitator I2. The gas cooling chamber 10 and the electric precipitator 1
The residue captured in step 2 is transported and stored in the residue storage tank 2 via the dust treatment stage fl17a, while the residue is transferred to the residue storage tank 2 and stored in the combustion furnace 9.
The sand forming the fluidized sand layer inside is sent to the discharger 1 together with non-combustible materials.
Vibration from 4! At step i15, the sand sorted and collected here is circulated back to the combustion furnace 9 by the sand return conveyor +6 as shown in the figure, and the sorted noncombustibles are sent to the magnetic separator 17.
In step (b), iron content and other non-combustible materials are sorted, and the iron content is stored in the residue storage tank 3, and the non-combustible substances are stored in the residue storage tank 4.
The sewage discharged from the bottom of the waste storage tank 8 and collected is sprayed and supplied to the combustion chamber of the combustion furnace 9 via the pipeline 18, where it is incinerated and decomposed.

Further, the foul-smelling air generated in the waste supply stage vaC is suctioned and pressure-fed by the forced air blower 19, heat exchanged in the air preheater 11, and the heated air is sent to the wind box 20 of the combustion furnace 9. It is used for blowing up jets of fluidized sand bed. In the figure, 21 is a cooling water tank, and the cooling water is supplied to the combustion furnace 9. The gas is to be supplied to the cooling chamber IO.
