Description
Technical field
The invention belongs to industrial exhaust heat and utilize the field, especially relate to a kind of heating system that utilizes self-priming negative pressure can regulate waste heat in the heat carrier furnace.
Background technology
The utilization rate of waste heat that carbon element is produced in existing technology is not high, the flue gas of from boiler, discharging, generally be directly be discharged into airborne.The flue-gas temperature at boiler export place is high, directly is discharged in the air not only contaminated environment, and wastes energy.How the heat with high-temperature flue gas fully utilizes, and is the problem that present carbon calcining and similar industry will solve.
Summary of the invention
The problem to be solved in the present invention provides a kind of waste heat heat carrier combustion heat supplying system, and the passive delivery waste heat heat carrier combustion system of heating station especially can be provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of heating system that utilizes self-priming negative pressure can regulate waste heat in the heat carrier furnace, system comprises calcining furnace, heat carrier furnace, quirk, chimney, with the flue that above device connects in turn, heating system, and through in the described heat carrier furnace and with heat-conducting oil pipes with hot equipment connection, it is characterized in that: also comprise the heating water heater, described heating water heater internal placement heat-conducting oil pipes, the outside heating system that connects.
Further, the outer connecting electronic water treatment facilities of described heating water heater.
Further, described heating system connects the water dirt separator outward.
Further, between described heating system and the heating water heater water supply tank is set.
Further, described heat-conducting oil pipes terminal arranges the conduction oil storage tank.
Further, on the described heat-conducting oil pipes circulating pump is set, the deep fat filter is set on the heat-conducting oil pipes behind the circulating pump.
Further, described chimney outer wall is coated with heat-insulation layer.
Advantage and good effect that the present invention has are: owing to adopt technique scheme, take full advantage of the burner exhaust heat energy in the carbon element production UTILIZATION OF VESIDUAL HEAT IN heating system, combustion system is more energy-conservation, and the structure of system is simpler, it is more convenient to operate, and has reduced human cost; Simultaneity factor is easy to maintenance, processing cost reduces, and has really realized the burning process of the energy-conserving and environment-protective of passive delivery, zero-emission.

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.
