Example Embodiment

[0046] Example 2

[0047] like Figure 3 to 4 , The present embodiment is designed to force a high-temperature heat transfer system of the calcium carbide, comprising a heat recovery kiln 4, the electric Kamameshi 3, the blower fan 6, the cold wind, the jet nozzle 9 and blowing the heat exchanger 5 and the like structures.

[0048] Heat recovery furnace in the present embodiment in Example 4 the same structure 1, and the tube and jet nozzle in the cold provided 4 heat recovery kiln is also the same as in Example 1 arrangement 9, at the same time, the present embodiment the heat exchanger structure may be used in the embodiment of Example 1, other configurations may be used, when installing the heat exchanger, which will be higher than the height of the mounting position of the heat absorbing heat recovery kiln exhaust pipe 4.

[0049] Structure of this embodiment is designed in Example 1 except that the large: the blower without passing through the heat exchanger 5 through pipes di...

Example Embodiment

[0051] Example 3

[0052] The present embodiment is designed a method of producing a high temperature carbide, which Example 1 using the calcium carbide or by cooling the high temperature heat recovery carbide or calcium carbide as in Example 2 to force the heat exchange system embodiment.

[0053] Furnace calcium carbide production method is industrially used, coke and smelting in an electric furnace of calcium oxide, calcium carbide generated. At this time, the temperature of the baked carbide production furnace up to 1800 ℃ -2200 ℃. For instance, when the degree of calcium carbide furnace generally reached 2000 deg.] C, the specific heat capacity of 0.264 kcal / kg.℃, i.e. 1.1kJ / kg ℃, having a heat of 522.7 kcal / kg i.e. 2185kJ / kg. Conventional cooling method is the direct use of high temperature carbide electric winch or onto the trolley the cooling pot this row field, naturally cooled, the cooling process, the calcium carbide crusts from the inside outward strength to wit...

Abstract

The invention belongs to the technical field of energy conservation and emission reduction, and particularly relates to a high-temperature calcium carbide forced heat exchange system. The system comprises a heat energy recovery kiln, a calcium carbide pot, a blast fan, a cold air pipe, a jet nozzle, a blast heat exchanger and the like. Air flows forcibly, dissipation of heat energy in the calcium carbide pot is accelerated, air serves as a heat exchange medium, the heat exchange system has the advantages of being low in cost, convenient to use, high in universality and the like, most mature parts such as the heat exchanger and the blast fan in the market are used in the structure of the calcium carbide pot, the parts are not prone to damage and long in service life, and meanwhile have the advantages of being easy to maintain and replace, meanwhile, the built heat energy recovery kiln can be directly built by using a soil-rock structure, so that the cost is lower.

Description

technical field [0001] The invention belongs to the technical field of energy saving and emission reduction, and in particular relates to a forced heat exchange system for high-temperature calcium carbide. Background technique [0002] The main component of calcium carbide is calcium carbide, which is a white crystal and is also the basic raw material for the organic synthesis chemical industry. The industrial products of calcium carbide are gray-black lumps with conductive properties, and the higher the purity of calcium carbide, The better the conductivity. It reacts violently with water immediately to generate acetylene and release heat, so the environment of calcium carbide is often stored in a dry environment. [0003] In industry, the electric furnace smelting method is generally used to produce calcium carbide. Coke and calcium oxide are smelted in an electric furnace to generate calcium carbide. After the calcium carbide is produced, the furnace temperature is as hi...
