Abstract

A method for dry coke quenching comprises coke discharging in batches into the coke-quenching chamber and coke cooling with cooling agent. Then the coke is supplied to the device for coke discharge in batches. Thereafter the removal of cooling agent excess volume from the device for coke discharge in batches is carried out. At that removal of excess volume of cooling agent is carried out from the upper part of the storage tank. The coke is discharged to the transport facility.

Description

quenching chamber enters the bypass chamber. The main task of a useful model for development is called a cut-off. The main purpose of this dry coke quenching plant, which allows measuring the batch discharge of coke from the quench chamber to reduce the amount of emissions of the cooling agent in the requirements for the tightness of the shut-off valve during the discharge of coke from the batch juice means. The task of the following shutters consists in the hermetic discharge of coke from the area of operation of the means of portioned discharge from the discharge means. of the cooling agent into the environment. Also, the task of a useful model is to reduce the environment. Therefore, the conditions for the tightness of these values of pressure drops of the cooling agent are very high. and in a means of portioned coke discharge.

As a result, USGK works in a certain aerodi- Also, the task of a useful model is to expand the intended mode, namely, in the upper part of the arsenal of dry coke quenching methods. ry of coke quenching maintain the pressure value, close to other tasks and advantages of a useful model that is close to the atmospheric (the so-called aerodynamic zero) that prevents the emission of cooling of a valid description and drawings. lodging agent during feeding (loading) of coke into the coke quenching chamber, and also prevents the removal of excess volume of cooling agent from entering the cooling agent from the upper part of the bypass chamber, the presence of which in the cooling agents, in which coke enters from the coke extinguishing chamber, leads to coke combustion. Maintenance in the upper part of the bypass chamber, in the part of the coke extinguishing chamber of the aerodynamic nu- where the coke comes from the coke extinguishing chamber, is carried out due to the removal of the excess volume of the cooling agent. into the atmosphere of the chewing agent. through a candle (a means of removing the excess volume of the cooling agent) of the circulation system, the set problems are solved by the fact that the known cooling agent. The candle of the system of dry quenching of coke, which contains the cooling agent, is installed after the metered loading of coke into the quenching chamber of the thrust device. During the operation of the USGK in the coke, in the lower part of the coke quenching chamber, the pressure value of coke cooling in the said quenching chamber exceeds the atmospheric pressure by 200-300 kgf/m", because of the coke cooling agent that circulates in the valve (cutoff) is not airtight , then cooling in the circulation system of the cooling agent, the masticating agent enters the supply of coke from the coke quenching chamber unhindered into the bypass chamber into which coke enters from the portioned coke discharge chamber, which contains coke quenching. During the next discharge of coke, at least two in a row with connected by-passes from the indicated by-pass chamber to the next by-pass chamber, a sharp pressure drop occurs in the chamber.

A known method and installation of dry quenching of the coking agent, ksu (international application M"PCT/ШШША2008/000072). unloading of coke from a batch digester

The well-known method of dry coke quenching, which includes the loading of coke on a vehicle, accordingly, to the useful model, the claimed dosed loading of coke into the quenching chamber, the removal of the excess volume of coke, the cooling agent from the means of batch cooling of coke in the said quenching chamber is carried out loading of coke, while removal of excess coke by the cooling agent, which circulates in the volume of the cooling agent, is carried out in the cooling agent circulation system from the upper part of the bypass chamber, into which the supply of coke from the coke quenching chamber to the means where coke enters from the quenching chamber coke batch discharge of coke, which contains, in a separate version of the method, at least two serially connected bypass excess volume of the chamber, the cooling agent, which is removed from the outlet of the excess cooling volume of the upper part of the bypass chamber, is removed from the , atmosphere. unloading of coke from a means of batch extraction. excess volume

The disadvantage of the known method is that during the unloading of the cooling agent, which is removed from the coke from the dry coke quenching chamber in the upper part of the bypass chamber, an additional waste boiler jam is formed in which significant pressure drops occur, which in turn, air-thermal disinfection of the cooling agent leads to inefficient operation of the portioning tool. discharge of coke, to increase the requirements. Drainage of the excess volume of the cooling-tightness of the shutters of the batching agent, from the upper part of the coke bypass, and also leads to emissions of the ohmmeter, into which the coke enters from the coke extinguishing chamber of the lodge of the agent into the working zone of the conveyor allows to reduce the value of pressure fluctuations of the protective agent. of the lodging agent in the means of batch extraction
