专利汇可以提供Explosive-proof method and incinerator for burning drill cuttings专利检索，专利查询，专利分析的服务。并且An incinerator for removing hydrocarbon residues and other organic and inorganic components from oil and gas well drill cuttings is submerged in water to make the assembly explosiveproof with respect to the drilling rig. One embodiment uses a basket with a removable bottom in the cumbustion chamber to retain the cuttings during the burning. An alternate embodiment uses a series of metal plates for such retention. After burning, the pollution-free cuttings are discharged from the combustion chamber beneath the surface of the water to eliminate sparks which might otherwise also cause an explosion. A belt-driven scoop located beneath the cumbustion chamber provides a means of testing the burned cuttings for unburned pollutants.，下面是Explosive-proof method and incinerator for burning drill cuttings专利的具体信息内容。

权利要求

1. An explosive-proof apparatus for burning hydrocarbons from drill cuttings on an offshore drilling barge, comprising: means for accumulating drill cuttings above the surface of the water; and submerged means for burning said cuttings beneath the surface of the water.

2. An explosive-proof apparatus for burning hydrocarbons from drill cuttings on an offshore drilling barge, comprising: a cuttings incinerator arranged to be submerged beneath the surface of the water; means for placing said cuttings into said incinerator; and means for displacing said cuttings from said incinerator into the water after burning.

3. The apparatus according to claim 2, including in addition thereto means for obtaining a sample of the cuttings after displacement from said incinerator.

4. An explosive-proof apparatus for burning hydrocarbons from drill cuttings on an offshore barge, comprising: an accumulator for accumulating said cuttings; a combustion chamber submerged beneath the surface of the water; an air-pressurized chamber connecting said accumulator with said combustion chamber; a first valve between said accumulator and said air-pressurized chamber; and a second valve between said combustion chamber and said air-pressurized chamber, whereby the sequential operation of said first and second valves causes said cuttings to be moved from said accumulator to said combustion chamber.

5. The apparatus according to claim 4 including in addition thereto retention means for retaining said cuttings while said cuttings are burning.

6. The apparatus according to claim 5 wherein said retention means comprises a mesh basket with means to empty said basket following the burning completion.

7. The apparatus according to claim 5 wherein said retention means comprises at least one metal plate mounted in said combustion chamber to receive said cuttings from said air-pressurized chamber, and includes means for removing said cuttings from said metal plate.

8. The apparatus according to claim 7, wherein said means for removing said cuttings comprises at least one scraper blade mounted on a rotatable shaft in a scraping relationship to said at least one metal plate.

9. The apparatus according to claim 7 wherein said at least one metal plate comprises a plurality of vertically spaced metal plates, each of said plates having a discharge port therein, wherein said ports in adjacent plates lie in different vertical planes, respectively.

10. The apparatus according to claim 9, wherein said means for removing said cuttings comprises a plurality of scrapper blades mounted on a rotatable shaft, at least one of said blades being mounted on said shaft for each of said plurality of metal plates in scraping position thereto.

11. A method for disposing of pollutants in drill cuttings, comprising: accumulating said cuttings; moving said cuttings to a combustion chamber beneath the surface of a body of water; burning said pollutants; and releasing said cuttings into the water.

12. The method according to claim 11, wherein said moving step comprises the gravity dropping of said cuttings onto at least one metal plate.

13. The method according to claim 11, wherein said releasing step occurs beneath the surface of the water.

14. The method according to claim 13, comprising, in addition thereto, the step of sampling said released cuttings to ascertain adequate burning of said pollutants.

15. An incinerator for burning hydrocarbons from drill cuttings on an offshore barge, comprising: a combustion chamber mounted on said barge; an input port on said combustion chamber for feeding cuttings thereto; and a submerged discharge outlet connected to said combustion chamber, whereby said cuttings and exhaust gases from said combustion chamber can be discharged beneath the surface of the water.

16. An explosive-proof apparatus for burning hydrocarbons from drill cuttings, comprising: a cuttings incinerator arranged to be submerged beneath the surface of a non-combustion supporting fluid; means for placing said cuttings into said incinerator; and means for displacing said cuttings from said incinerator after burning.
