Definitions
- the present group of inventions relates to the coke industry and can be used in dry quenching systems of coke (hereinafter CCTC).
- Dry coke quenching methods and devices implementing them are based on cooling coke in a coke quenching chamber with a cooling agent that circulates in the cooling agent circulation system (see M. Teplitsky et al. Dry coke quenching, M., “Metallurgy”, 1971, US patent NQ 3895448, publ. 07/22/1975; US patent NQ 4141795, publ. 02/27/1979).
- the coke quenching chamber is a vertically located shaft lined with refractory masonry, into which coke is supplied by means of metered loading.
- Coke quenching in the coke quenching chamber is carried out by passing a cooling agent through the coke layer, which is inert with respect to coke.
- the cooling agent circulation system usually contains a coarse filter, usually made in the form of a dust collecting bin, a recovery boiler, which is a relatively tight chamber in which heat-exchanging surfaces are placed, to which the cooling agent gives off heat, and means for removing the excess volume of the cooling agent from the circulation system of the cooling agent.
- a fine filter of the cooling agent made in the form of a cyclone, is installed, followed by a blower device, for example, a smoke exhauster.
- a candle enters the circulation system of the cooling agent as a means for removing the excess volume of the cooling agent that is formed in the circulation system of the cooling agent as a result of air suction.
- the CCPF operates in a specific aerodynamic mode, namely, in the upper part of the coke quenching chamber, a pressure close to atmospheric pressure (the so-called aerodynamic zero) is maintained, which prevents the release of a cooling agent during coke loading into the coke quenching chamber, and also prevents into the cooling agent of air, the presence of which in the cooling agent leads to the burning of coke.
- the aerodynamic zero in the upper part of the coke quenching chamber is maintained by draining the excess volume of the cooling agent into the atmosphere through the candle of the cooling agent circulation system.
- the candle of the cooling agent circulation system is installed after the draft device.
- the pressure value exceeds atmospheric by 200-300 kgf / m 2 , due to the high resistance of coke during the passage of the cooling agent through the coke, which leads to emissions of the cooling agent from the coke quenching chamber at the time of coke unloading a vehicle, such as a conveyor.
- a means for continuous coke unloading is installed in which a pressure equal to atmospheric pressure is created, the so-called “air shutter”.
- the pressure value in the means for continuous unloading of coke, which is equal to atmospheric is created using the recirculation circuit of the cooling agent and the circuit of the gas mixture.
- the coolant recirculation loop is associated with a means for continuously discharging coke and a circulation system for the cooling agent, which reduces the vacuum in the means for continuously discharging coke and ensures safe unloading of coke to the vehicle, and also prevents emissions into coolant atmosphere.
- the circulation circuit of the gas mixture is a circuit that is adjacent to the means for the continuous discharge of coke.
- a gas mixture circulates along the circuit, which was formed during the mixing of the cooling agent with air, which enters the circuit of the gas mixture as a result of suction through a means for the continuous discharge of coke.
- the circulation of the gas mixture is carried out through the use of a smoke exhauster installed in the circulation circuit of the gas mixture.
- a dust-collecting cyclone is installed in the circulation circuit of the gas mixture, designed to reduce the wear of the smoke exhaust, as well as increase the efficiency of dust removal of coke.
- the circulation circuit of the gas mixture reduces the likelihood of the release of the cooling agent during the operation of the CCPD, and also allows to achieve effective dedusting of coke and allows for the effective degassing of coke, namely, to remove the cooling agent from the pores of the coke and the inter-bite space.
- the determination of the amount of air suction in the circulation system of the cooling agent is carried out in the process of operation of the CCP. So, during the operation of the CCP, the pressure sensor, which is located in the upper part of the CCP, constantly monitors the pressure value in the upper part of the coke quenching chamber. With increasing pressure in the upper part of the coke quenching chamber, excess coolant is discharged from the cooling agent circulation system through a candle into the atmosphere. During the discharge of the excess volume of the cooling agent through a candle into the atmosphere, measurements of the amount of cooling agent are carried out using known means, for example, flowmeters. Then determine what excess volume of the cooling agent was discharged into the atmosphere per unit time (h).
- the obtained value is divided by the value of the amount of cooling agent that was extinguished by coke quenching in the coke quenching chamber for the same period of time (h), after which the air suction coefficient is obtained.
- the effectiveness of the USTK is judged.
- the coefficient of air suction in the CCP can be up to 15%. With the coefficient suction of air equal to 15% or more USTK stop for major repairs.

- the cooling agent circulation system is provided with means for removing an excess volume of the cooling agent in the form of a candle.
- the aerodynamic zero is maintained in the upper part of the coke quenching chamber by dumping into the atmosphere an excess volume of the cooling agent through the aforementioned candle.
- the disadvantage of the STCC and the method implemented therein is that the aerodynamic zero is maintained in the upper part of the coke quenching chamber by dumping an excess volume of the cooling agent into the atmosphere through a candle, which leads to environmental pollution.
- the cooling agent contains about 6% carbon monoxide, whose calorific value is 3270 kcal / m 3 .
