Description

Carbon black tail gas dewatering device
Technical Field

Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Carbon black is an important chemical raw material and is widely applied to various fields of rubber, plastics, coatings, printing ink, war industry, communication, electronics, telecommunication, household appliances, cables, optical cables, high-energy batteries, electrostatic copying, photosensitive materials, printing and dyeing, papermaking, metallurgy and the like. The development of the carbon black industry promotes the social progress, but also increases the pollution to the living environment of human beings.
The carbon black industry has always been an industry with high energy consumption and high pollution. With the rapid development of the automotive industry, the demand for carbon black is also increasing. For the development of the carbon black industry, the carbon black production method not only continuously adapts to the market requirement, but also needs to excavate the internal potential of the carbon black, reduce the energy consumption of the carbon black production, fully utilize the waste heat in the carbon black production, realize the cyclic utilization of resources and reduce the pollution.
The carbon black tail gas is a byproduct generated in the carbon black production process, and in the carbon black production process, the CO and H can be generated through pyrolysis of raw oil2And waiting for the waste gas of the combustible gas, wherein the waste gas is the carbon black tail gas. The carbon black tail gas comes from a carbon black reaction furnace, contains carbon black powder, and is generally discharged after being purified by a main bag filter. Due to the technological requirements of carbon black production, a large amount (about 10-15 m) of carbon black needs to be sprayed3And/h) cooling by using quenching water, so that the water content in the carbon black tail gas is higher and is about 36-40%. The carbon black tail gas has high water content, low heat value, more complex components, water content and NH3Dust, etc. In order to avoid pollution, the carbon black tail gas needs to be recycled.
The carbon black tail gas is mainly used as a drying furnace fuel or a tail gas boiler fuel in the carbon black industry. The carbon black tail gas boiler can recover tail gas discharged in the carbon black production process and convert chemical energy in the carbon black tail gas into heat energy. By this conversion, substances such as hydrogen, methane, and carbon monoxide in the carbon black off-gas are converted into water and carbon dioxide.
However, when the carbon black tail gas is utilized, the amount of coal gas used for recovering the carbon black tail gas is increased, the power consumption is increased and the partition wall of the regenerator of the coke oven is seriously corroded due to the high water content of the carbon black tail gas. Therefore, the dehydration of the carbon black tail gas is particularly important.

Please refer to fig. 1. The embodiment of the application provides a carbon black tail gas dewatering device, and the device comprises a waste heat recovery mechanism 2, a spraying container 3 and a circulating mechanism. The carbon black tail gas treated by the method can be generated after being filtered by the main bag filter 1, the water content of the carbon black tail gas is about 36%, and the temperature of the carbon black tail gas is about 230 ℃. Of course, the carbon black tail gas water content and the temperature that produce under different operating modes are different, and the device that produces carbon black tail gas also can be different, and this application embodiment does not do the restriction to this.
The waste heat recovery mechanism 2 is provided with a heat exchange tube 12 for exchanging heat with the carbon black tail gas. The temperature of the carbon black tail gas discharged from the waste heat recovery mechanism 2 is higher than the flue gas dew point of the carbon black tail gas. The flue gas dew point refers to the temperature at which the acidic species (e.g., hydrogen sulfide) in the carbon black tail gas begin to condense. The spraying container 3 is positioned at the downstream of the waste heat recovery mechanism 2. The spray container 3 has an inlet 11 and an outlet 10. The inlet 11 is located in the lower half of the spray container 3. The outlet 10 is located at the top of the spray container 3. The spraying container 3 is internally provided with a filling part 4 and a spraying part 9. The filler part 4 is located between the inlet 11 and the outlet 10.

Moreover, the temperature of the carbon black tail gas discharged from the waste heat recovery mechanism 2 is higher than the flue gas dew point of the carbon black tail gas, so that the waste heat recovery mechanism 2 cannot be corroded at low temperature.
In addition, by arranging the circulating mechanism, the liquid in the liquid storage part can be recycled, and the leakage of volatile smell such as ammonia contained in the condensed water in the carbon black tail gas is avoided.
In the embodiment of the present application, the carbon black tail gas dehydration device washes the carbon black tail gas by the spray container 3, and cools and dehydrates the carbon black tail gas. Thus, the heat in the carbon black off-gas is replaced into the circulating water (i.e., the liquid sprayed by the spraying section 9), so that the temperature of the circulating water in the spraying container 3 is increased. In order to effectively cool and dehydrate the carbon black tail gas by the circulating water, the heat in the circulating water must be replaced again.
Therefore, a heat exchanging part 5 can be arranged between the circulating pump 6 and the spraying part 9, so that the liquid in the liquid storage part can realize closed circulation. Specifically, the heat exchanging portion 5 may be a plate heat exchanger. Other cooling water pipe networks are introduced into the plate heat exchanger, and heat in circulating water in the spraying container 3 is replaced, so that the circulating water in the spraying container 3 is cooled, carbon black tail gas can be cooled and dehydrated circularly, and leakage of carbon black tail gas condensate water odor (pungent odor of volatile gases such as ammonia gas) is avoided.

In this regard, the pitch of the fins may have a predetermined width to reduce the occurrence of clogging. Specifically, the pitch of the fins is not less than 10 mm.
The arrangement of the heat exchange tubes 12 is not limited in the embodiments of the present application. Preferably, the flowing direction of at least part of the liquid in the heat exchange tube 12 is perpendicular to the flowing direction of the carbon black tail gas in the waste heat recovery mechanism 2, so as to enhance the heat exchange effect.

An air flow distributor, such as a tubular air flow distributor, can be arranged between the packing part 4 and the inlet 11, so that the carbon black tail gas is distributed more uniformly in the whole spray tower. The spray section 9 may include a trough distributor to provide a more uniform distribution of spray throughout the spray tower. This spray container 3 has strengthened the abundant contact of carbon black tail gas and circulating water, and carbon black tail gas has sufficient dwell time to make cooling effect good, the dehydration is more abundant.
In the embodiment of the present application, the spraying part 9 may have three layers, and the spraying nozzle may be made of ceramic or polypropylene. A flushing part can be arranged between the spraying part 9 and the outlet 10 and is used for flushing impurities in the carbon black tail gas and taking away heat in the carbon black tail gas. The washing part can be provided with two layers for spraying washing water, and the nozzle can be made of polypropylene materials.
