Chinese patent CN101270234A discloses a manufacturing method of soft carbon black, which is suitable for the production of soft carbon black, because the production of soft carbon black does not require high temperature, while the production temperature of hard carbon black is required to achieve the purpose Above 1900°C, so this method cannot be used for the production of hard carbon black
The inventor has obtained the Chinese patent ZL200920080818.3 which discloses an energy-saving device for the production of hard carbon black, but this patent does not mention the oxygen-enriched combustion of the tail gas, so that the combustion temperature is not easy to reach the production of hard carbon black. temperature requirements

The energy-saving device for producing the hard carbon black are characterized by comprising a hard carbon black reaction furnace (7), a high-temperature air preheater (13) of a first smoke outlet (10), a tail gas preheater of a second smoke inlet (21) and a second smoke outlet (22), a raw oil preheater of a third smoke inlet (14) and a third smoke outlet (15), a low-temperature air preheater (25) and a low-pressure fan (35) sequentially, wherein the low-temperature air preheater (25) and the low-pressure fan (35) are communicated with a tail gas outlet (19) of a bag filtering box; the low-temperature air preheater is communicated with a condenser (26); the condenser is communicated with a gas-water separator (27); and a flow valve is communicated with a recovery tail gas inlet (23) of the tail gas preheater. A tail gas flow distributing valve (37) is arranged between the tail gas outlet (19) and the low-temperature air preheater (25); the low-pressure fan (35) is arranged between the low-temperature air preheater and the condenser; an oxygen-enriched mixer (36) and an oxygenator (31) are arranged between a high-temperature air outlet (8) of the high-temperature air preheater and a high-temperature oxygen-enriched air inlet (4); and the oxygen-enriched mixer is connected with the oxygenator.

Description

Technical field: [0001] The invention relates to an energy-saving device for producing hard carbon black and a production method thereof, belonging to the field of carbon black production. Background technique: [0002] The existing carbon black production has always been to use burning fuel to provide the thermodynamic energy required for the cracking of raw materials. When the raw material oil is cracked to generate carbon black, the tail gas associated with it contains a large amount of combustible substances such as CO, H2, CH4, etc. ingredients. The current method is to use tail gas combustion for waste heat power generation, and use the power grid to provide electricity for the society. In addition to meeting its own power needs, waste heat power generation is redundant, but the cost of waste heat power generation is high and the efficiency of heat energy recovery and utilization is very low. In order to achieve the purpose of improving the recovery efficiency of hea...
