专利汇可以提供Thermolytic sewage system专利检索,专利查询,专利分析的服务。并且A system for treating sewage in which the sewage passes a grinder to reduce the solids and then goes into a holding tank under ground. The sewage flows from the holding tank to an evaporator with the products of combustion flowing over water heating coils and under the holding tank to heat the sewage water and to preheat the holding tank. Condensate from the products of combustion flows to a holding tank and from there into the ground with the gaseous material passing off through a stack.,下面是Thermolytic sewage system专利的具体信息内容。

1. A sewage treatment plant comprising a sewage holding tank, a sewer pipe extending into said tank, means in said sewer pipe for comminuting sewage passing through said sewer pipe to said holding tank, a dry well positioned adjacent said holding tank and having a depth substantially greater than said holding tank, an evaporator mounted in said dry well adjacent the bottom thereof, means for gravity feeding sewage from said holding tank to said evaporator, means in said evaporator for spreading the sewage flowing from said holding tank, a heater mounted in the bottom of said evaporator for heating the sewage flowing into said evaporator from said holding tank, and a conduit extending from said evaporator in heat exchange relation with said holding tank for preheating the sewage in said holding tank prior to delivery to said evaporator.
2. A device as claimed in claim 1, wherein said grinder comprises a generally spherical rotary grinding member and water actuated means for rotating said grinding member.
3. A device as claimed in claim 1, wherein means is provided in said holding tank actuated by the height of sewage in said tank for energizing the burner in said evaporator.
4. A device as claimed In claim 1, wherein a motor actuated valve is mounted in the means for feeding sewage from said holding tank to said evaporator with said valve being controlled in response to the temperature in said evaporator.
5. A device as claimed in claim 1, wherein the means for spreading the sewage in said evaporator comprises a splash plate positioned centrally of said evaporator and a plurality of baffles positioned therearound to receive the splash from said splash plate.
6. A device as claimed in claim 1, wherein a heat exchanger is provided in the conduit means extending from said evaporator for heating domestic water.
7. A device as claimed in claim 1, wherein means are provided in said conduit means extending from said evaporator for collecting condensate resulting from the products of combustion.
8. A device as claimed in claim 1, wherein a vent stack communicates with the conduit means extending from said evaporator to vent said conduit means to the atmosphere.
9. A device as claimed in claim 1, wherein a vent cap is mounted on said dry well for admitting atmospheric air to said dry well for use by said evaporator.
10. A device as claimed in claim 1, wherein a stack extends upwardly from said evaporator and a plurality of additional air vents extend into said stack to admit extra air to said stack as required.
