摘要:
The invention discloses an electrical heating coal material decomposition apparatus, which includes a closed kiln body (1) with a feed inlet (2) and a discharge outlet (3). An electrical heating device (4) is arranged in the kiln body (1). A propulsion and decomposition path of coal material (10) is formed between the electrical heating device (4) and the inner wall of the kiln body (1). A coal decomposition gas collecting pipe (5) which is communicated with the propulsion and decomposition path of coal material (10) is arranged on the kiln body (1). The coal decomposition gas collecting pipe (5) is connected with a gas dust-traping and liquefying device (8) which is arranged outside the kiln (1). The electrical heating device (4) transfers mass of heat produced to the pulverized coal inside the propulsion and decomposition path of coal material (10) by conduction and irradiation. The pulverized coal absorbs heat sufficiently and achieves increase in temperature. It is decomposed into fuel gas, tar gas and coal with high heat value inside the propulsion and decomposition path of coal material (10). The fuel gas and tar gas enter the gas dust-trapping and liquefying mechanism (8) through the decomposed gas collecting tube (5). The decomposed fuel gas and tar gas are collected, dust-trapped, separated and liquefied under pressure.

The invention discloses a non-electroslag remelting type clean metal ingot mold comprising an ingot mold body and a insulating riser arranged on the ingot mold body; an insulated heating and heat preservation device is vertically arranged in the ingot mold body and divides the space in the ingot mold body into a plurality of independent cavity units; and the cavity units are distributed in two rows in the ingot mold body. Because the insulated heating and heat preservation device is arranged in the ingot mold body and divides the space in the ingot mold body into a plurality of independent cavity units, most of impurities and segregates in liquid metals are enriched in the part in contact with the isolation and heat insulation mechanism during the directional solidification and crystallization of the liquid metals and the enriched alloy segregates, and the impurities can be easily eliminated by utilizing flame or other processing methods. Therefore, the transfer and the elimination of the segregates and the impurities in ingots can be realized, and the purpose of purifying the ingots is achieved.

The invention discloses a coal decomposition equipment including an airtight kiln body with an inlet and an outlet, wherein a flame gas pipeline heating facility is set in the kiln body and a channel for impelling and decomposing coal is formed between the flame gas pipeline heating facility and an inner wall of the kiln body; and a coal decomposition gas collecting pipe is provided on the kiln body to communicate with the channel. Since the present invention makes the vast thermal conduction produced by the flame gas pipeline heating facility and radiate to the coal power in the coal substance impel decomposition channel. The pulverized coal fully absorbs the heat so as to be heated and decomposed to the gas, coal tar gas and coal with a higher heat-value in the channel.
摘要:
Disclosed is a vertical pyrolysis equipment for coal material, which comprises an enclosed kiln body with an inlet and an outlet, a flame-gas heating pipelines provided inside the kiln body, coal material propulsion and pyrolysis passage formed between the flame-gas heating pipelines and inner wall of the kiln body, coal pyrolysis gas collecting tube communicated with the coal material propulsion and pyrolysis passage provided on the kiln. The heat generated by flame-gas heating pipelines is conducted and radiated to coal powder in the coal material propulsion and pyrolysis passage. The coal powder sufficiently absorbs the heat and is pyrolyzed into fuel gas, tar gas and coal with high heat value inside the coal material propulsion and pyrolysis passage. The pyrolyzed fuel gas and tar gas are transferred to the gas dedusting-liquifying mechanism outside the kiln through the connecting coal pyrolysis gas collecting tube for collecting, dedusting, separating and high-pressure liquefying.
