Definitions
- the invention relates to a method for eliminating the thick tea obtained in the cooling of coke oven gas and to a mixing container which is particularly suitable for carrying out this method.
- the composition is in the following range:
- the amount of thick tar obtained when charging the coke oven battery with wet coal is about 3 - 9 kg thick tar per 1000 m3 of coke oven gas. If, on the other hand, the coke oven battery is charged with preheated coal, the amount of thick tar can increase by 5o - 100% of the above values. Due to its high solids content, processing of the thick tea in a subsequent tar distillation is not possible. However, since there is no other suitable processing option for the thick tar, it must be removed in a suitable manner.
- the invention is therefore based on the object of providing a method for eliminating the thick tea obtained in the cooling of coke oven gas, which requires little work and at the same time enables an environmentally friendly and largely automated procedure.
- the method used to achieve this object is characterized according to the invention in that the thick tar is comminuted to a particle size of 1 1 mm and diluted by adding a tar-water mixture, the resulting mixture being kept at a temperature between 55 and 75 ° C and then placed on the coal on the raw coal conveyor belt.
- the thick tar obtained is first comminuted in a solids mill to a particle size of 1 1 mm and then diluted by adding a tar-water mixture.
- the tar-water mixture is preferably added in such an amount that the resulting mixture contains 15 to 30% by weight of thick tar and 7o to 85% by weight of the tar-water mixture.
- the water content of the tar-water mixture used as a diluent can vary within a wide range.
- the water content can preferably be between 40 and 60% by weight. However, applications are also possible in which it is below 5% by weight.
- the mixture obtained during the dilution normally already has an elevated temperature. After dilution, however, it must be ensured that the resulting mixture is kept at a temperature between 55 and 75 ° C. Here, the temperature is set so that the viscosity of the mixture is brought to a value which enables the same to be distributed evenly.
- the warm mixture is then pressed onto the distributing devices, through which it is evenly applied to the feed coal located on the raw coal conveyor belt. Together with this coal, the thick tar then gets back into the oven chambers of the coke oven battery.
- Coking processes are known in which limited amounts of normal tar or a certain tar oil fraction have been added to the feed coal.
- this addition was made solely for the purpose of improving the coking properties of the coal, the tar or the tar oil fraction added serving as a binder and the coal being subjected to subsequent compression by stamping or briquetting.
- This known method could not provide any suggestions for the realization of the method according to the invention, since on the one hand no thick tar is used and on the other hand no subsequent compression of the coal sprayed with thick tar is provided in the method according to the invention.
- the thick tar should not serve as a binder and should not otherwise improve the coking properties of the coal used.
- the addition of thick tar in the process according to the invention is also not limited in quantity, but is based exclusively on the accumulation of thick tar in the gas treatment plant, it being possible for the entire accumulating thick tar to be fed onto the coal used.
- the figure shows a separating container (1) in a characteristic embodiment, which is common in coking technology.
- the three phases of water, tar and thick tar are separated from the tar-containing condensate in this separating container ((D) in the order given Scraper chain conveyor (2) is gripped and transported from there to the tip of leg 3.
- the thick tar falls through the discharge opening (4) into the one below Solid mill (5) in which the coarse pieces of thick tar are ground to a particle size of ⁇ 1 mm.
- the thick tar particles then enter the mixing container (22), which is provided with a heating jacket (7).
- the tar-water mixture required for diluting the thick tar is introduced into the mixing container (22) via the line (8) provided with the valve (9).
- the screw conveyor (23), which is driven by the external motor (6), is arranged on the bottom of the mixing container (22).
- the temperature of the mixture in the mixing container (22) is kept between 55 and 75 ° C, preferably at 60 ° C.
- the temperature is continuously monitored by the temperature measuring device (1o), the measured value being transmitted via line (11) to the controller (12), which controls the heating of the heating jacket (7).
- the temperature is controlled within the specified range in such a way that the mixture in the mixing container (22) has a sufficiently low viscosity which permits the same to be distributed evenly.
- the warm mixture which preferably has a temperature of approximately 60 ° C., is conveyed to the suction point of the submersible pump (13) by means of the screw conveyor (23).
- This can be, for example, a so-called channel wheel pump, which presses the heated mixture via the line (14) onto the thick tar nozzle (15).
- the mixture is sprayed uniformly onto the feed coal located on the raw coal conveyor belt (16) through the thick tar nozzle (15).
- the valve (17) is arranged in the line (14) shortly before the thick tar nozzle (15) and is automatically closed when the raw coal conveyor belt (16) is at a standstill. This prevents a further task of the mixture containing thick tar during the belt standstill.
