Abstract
The invention discloses a heat energy recycling device for nitriding furnaces, which is provided with a plurality of nitriding furnaces. The heat energy recycling device for the nitriding furnaces is characterized in that the exhaust pipes of the nitriding furnaces are communicated with the input end of a cooler through a pipeline, the output end of the cooler is connected with a draught fan, the output end of the draught fan is respectively communicated with the nitrogen input pipes of the nitriding furnaces through high temperature pipes. High temperature valves are arranged on the nitrogen input pipes, therefore, a sealed cycling system is formed. Heat energy for temperature reduction in the furnace can not lose, and residual nitrogen can be utilized. The invention has the advantages of high energy utilization ratio, high smelting speed, low cost, zero emission and environmental protection.
Description
Technical field
The invention belongs to the metallurgical smelting unit technical field, be specifically related to a kind of nitriding furnace heat energy recycling device.
Background technology
Nitriding furnace is an equipment commonly used in the metallurgical smelting unit, comprise furnace wall and furnace roof, furnace roof has the arch arch, be furnished with electric heater unit, nitrogen access equipment and gas barrier, the nitrogen input tube is arranged in the nitrogen access equipment, vapor pipe is arranged in the gas barrier, and its nitrogen input tube passes through thermal insulation layer from a wing furnace wall top and enters burner hearth, and vapor pipe enters burner hearth from wing furnace wall bottom.The heat energy utilization structure of this nitriding furnace installs radiating pipe additional at the outside adding circulated water system of nitriding furnace body of heater and body of heater top and carries out heat energy utilization, more than two kinds of methods all undesirable.Because of the body of heater internal heat accumulates in the good enclosed space of heat insulation effect, the heat that the speed that the intravital thermal energy conduction of stove is lowered the temperature outside stove the does not catch up with cooling system far away speed of scattering and disappearing.Because of the restriction of technical matters, can not carry out direct convection current to body of heater inside and outside air.
Summary of the invention
For solving the above-mentioned defective that prior art exists, the object of the present invention is to provide a kind of energy utilization rate height, speed of melting is fast, and cost is low, realizes zero release, the nitriding furnace heat energy recycling device of protection environment.
For achieving the above object, the technical solution used in the present invention is: this nitriding furnace heat energy recycling device, have a plurality of nitriding furnaces, it is characterized in that: the vapor pipe of described a plurality of nitriding furnaces is communicated with the input terminus of water cooler by pipeline, the output terminal of water cooler connects induced draft fan, the output terminal of induced draft fan is communicated with the nitrogen input tube of nitriding furnace respectively by high-temperature pipe, and each nitrogen input tube is provided with high temperature valve.
Adopt the beneficial effect of technique scheme: the principle of this nitriding furnace heat energy recycling device is to be together in series nitriding furnace is airtight; heat energy is passed through closed circulation system; be incorporated into and carry out heat energy utilization in another stove; promptly the cooling energy of nitriding furnace is transported in another nitriding furnace by closed conduit and hot air circulation blower and heats up; thereby the raising energy utilization rate, the protection environment, purpose such as reduce cost.The invention reside in nitriding furnace itself is Sealing Arrangement, and stove is an intermittent operation, and as not using sealing and circulating heat energy utilization system, the intravital cooling heat energy of stove can lose meaninglessly, and unnecessary nitrogen can not obtain utilizing.By facts have proved, the present invention can improve energy utilization rate 20%, and every stove can be saved 500 yuan of the electricity charge, saves 100 yuan of system nitrogen energy charges, has remarkable economic efficiency.
Description of drawings
Below in conjunction with accompanying drawing specific embodiments of the invention are described in further detail.
Fig. 1 is a structural representation of the present invention.
Embodiment
Nitriding furnace heat energy recycling device as shown in Figure 1, have a plurality of nitriding furnaces 1,2,3,4,5,6, the vapor pipe 7,8,9,10,11,12 of nitriding furnace is communicated with the input terminus of water cooler 13 by pipeline, the output terminal that cools off 13 devices connects induced draft fan 14, the output terminal of induced draft fan 14 is communicated with the nitrogen input tube 16,18,20,22,24,26 of nitriding furnace respectively by high-temperature pipe 15, on each nitrogen input tube, be respectively arranged with high temperature valve 17,19,21,23,25,27, constitute the airtight recycle system.The intravital cooling heat energy of stove can not lost, and unnecessary nitrogen also can obtain utilizing, and has the energy utilization rate height, and speed of melting is fast, and cost is low, realizes zero release, the characteristics of protection environment.
Nitriding furnace of the present invention also can be 2 or 3 or more, utilizes structure of the present invention to constitute the airtight recycle system and all belongs to the scope that this patent is protected.
