The specific embodiment

As shown in Figure 1, the present invention introduces a kind of utilization and utilizes self-priming negative pressure can regulate the heating system of waste heat in the heat carrier furnace, and system comprises calcining furnace 12, heat carrier furnace 5, quirk, chimney 6, with the flue that above device connects in turn, heating system 9, and through in the described heat carrier furnace and with heat-conducting oil pipes with hot equipment connection, circulating pump 4 also comprises heating water heater 11, described heating water heater internal placement heat-conducting oil pipes, the outside heating system 9 that connects.

The outer connecting electronic water treatment facilities 10 of described heating water heater, the heating water that circulation is flowed out heating water heater 11 is processed, and reduces the content that causes the material of incrustation scale in the water.

Described heating system 9 outer connection water dirt separators 8 will be removed through the incrustation scale of heating pipe, avoid the impurity in the heating plant to enter circulatory system blocking pipe.

Between described heating system and the heating water heater water supply tank 7 is set.

Described heat conducting oil pipe terminal arranges conduction oil storage tank 1, and oil storage pump 3 is set on the heat conducting oil pipe, on the heat conducting oil pipe behind the described oil storage pump heat transfer oil filter 2 is set.

Described chimney 6 outer walls are coated with heat-insulation layer.

The course of work of this example: in the carbon element production process, incinerator 12 all produces a large amount of hydrocarbon fuel gas when the calcination petroleum coke, therefore these hydrocarbon gas can be conversely as the Combustion Source of calcination petroleum coke, and need not to provide in addition heating energy source.These hydrocarbons pass through fully and behind the petroleum coke combustion, produce a large amount of high-temperature flue gas, and its temperature can reach more than 900 ℃, and flow can reach 5000m 3/ h is transported to these high-temperature flue gas in the heat carrier furnace 5 with heating conduction oil wherein by flue, and conduction oil is transported to the heating water heater by pipeline, the heating water in the heating water heater.Heating water after the heating is transported to heating system with pump after electric water treatment device is processed incrustation scale, heating system is with after the heat, and the heating backwater is used pumped back heating water heater again after the water dirt separator is disposed dirt.Conduction oil is withdrawn in the heat carrier furnace by pipeline after the deep fat filter filters by circular-pump 3, and circulating-heating like this is to provide continual thermal source.Flue gas fully burns through entering quirk behind the heat carrier furnace, discharges from chimney at last.In this process, the negative pressure that the power resources that flue gas flows in flue produce the adjusting of aperture during in flue position separately in first to fourth valve.Mounting temperature sensor everywhere on the flue, by regulating the aperture of each throttle, the monitoring sensor temperature is controlled at about 800 ℃ flue-gas temperature, and about 200 ℃ of hot oil temperatures are realized producing negative pressure in the integrated piping, drive flow of flue gas.The heat-insulation layer that chimney increases also so that flue-gas temperature raising in the chimney brings larger climbing power, can reduce the height of chimney.When heat carrier furnace 5 was not worked, conduction oil was sent to the storage of deep fat storage tank.

Because the heat of heat carrier furnace is to be provided by the flue gas that the petroleum coke incinerator produces, power self-support, air blast and cooling device have been saved again simultaneously, also utilizing conduction oil to do conduction will discharge the waste heat of flue gas and carry out the application such as residential quarter heating, the energy consumption of whole carbon element production process will be reduced greatly, and production cost also significantly reduces.

This combustion system not only is applicable to carbon element production, can be used for equally other and utilizes burning to make the production of product.

More than one embodiment of the present of invention are had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
