Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
55 words
A mobile type medical refuse incinerating vehicle characterized in that an incinerator for incinerating medical refuse is mounted on a medical refuse carrier vehicle, said incinerator comprising a main burning furnace and an after-burning furnace which are communicated with each other, further comprising means for selectively injecting oil or water into said main burning furnace.
Claim 2
Dependent Claim
55 words
A mobile type medical refuse incinerating vehicle characterized in that an incinerator for incinerating medical refuse is mounted on a medical refuse carrier vehicle, said incinerator comprising a main burning furnace and an after-burning furnace which are communicated with each other, further comprising means for selectively injecting oil or water into said main burning furnace.
Claim 3
Dependent Claim
59 words
A mobile type medical refuse incinerating vehicle as set forth in claim 1, wherein lime water is used as said water, and the lime water is stored in a tank and injected into said main burning furnace through said injecting means so as to turn hydrogen chloride which is produced by combustion of the medical refuse, into calcium chloride.
Claim 4
Dependent Claim
31 words
A mobile type medical refuse incinerating vehicle as set forth in claim 2, wherein calcium hydroxide is mixed into said water so as to prepare said lime water in said tank.
Claim 5
Dependent Claim
43 words
A mobile type medical refuse incinerating vehicle as set forth in claims 1 or 2, wherein said injecting is an oil feed type rotary burner, and has a three-way valve for selectively changing over the injection of air, the oil and the water.
Claim 6
Dependent Claim
52 words
A mobile type medical refuse incinerating vehicle as set forth in claim 1, wherein ignition flame and secondary air are injected into an after-burner so that said ignition flame and said secondary air are forced to make contact with unburnt gas led from said main burning furnace, which is therefore burnt up.
Claim 7
Dependent Claim
38 words
A mobile type medical refuse incinerating vehicle as set forth in claim 1, wherein thermocouples are provided in said main burning furnace and said after-burning furnace so as to measure temperatures of the insides of said furnaces, respectively.
Claim 8
Dependent Claim
27 words
A mobile type medical refuse incinerating vehicle as set forth in claim 1, wherein said carrier vehicle self-travels under control of a driver in a drive cabin.
Claim 9
Dependent Claim
49 words
A mobile type medical refuse incinerating vehicle as set forth in claim 1, wherein a flue having an exhaust pipe, having its upper part opened to the atmosphere, is connected to said main burning furnace, and an ejector extending from an exhaust fan is inserted into said exhaust pipe.
Claim 10
Dependent Claim
64 words
A mobile type medical refuse incinerating vehicle as set forth in claim 1, wherein a hearth carriage having, on its upper surface, a hearth, is provided in the bottom section of said main burning furnace, said hearth carriage travels on rails laid on the bottom section of a cargo bed so that said hearth carriage can be pulled out from said main burning furnace.
Claim 11
Independent Claim
73 words
A method for incinerating medical refuse in a portable type medical refuse incinerator device, comprising the steps of: inserting medical refuse into the furnace of said incinerator; initiating the incineration of said medical refuse; measuring the temperature in said furnace; and adding water to said furnace if the temperature in said furnace is too high with respect to the desired maximum temperature, in order to maintain a substantially constant temperature in said furnace.
Claim 12
Independent Claim
73 words
A method for incinerating medical refuse in a portable type medical refuse incinerator device, comprising the steps of: inserting medical refuse into the furnace of said incinerator; initiating the incineration of said medical refuse; measuring the temperature in said furnace; and adding water to said furnace if the temperature in said furnace is too high with respect to the desired maximum temperature, in order to maintain a substantially constant temperature in said furnace.
Claim 13
Dependent Claim
22 words
The method of claim 10, further comprising the step of adding oil to said furnace of the temperature therein to too low.
Claim 14
Dependent Claim
34 words
The method of claim 10, further comprising the step of adding a solution of calcium hydroxide and water into said furnace in order to reduce the amount of dangerous gases formed in said furnace.
Claim 15
Dependent Claim
22 words
The method of claim 10, further comprising the step of further combusting the gases emitted from said burner in an after burner.
