Description

Technical Field

[0001] The invention relates to the technical field of tar ammonia water separation equipment, and in particular to a residual ammonia water separation tank. Background Art

[0002] The residual ammonia water in the coking plant is the product of the tar-ammonia water mixture that enters the gas purification system with the raw coal gas and passes through the tar-ammonia water separation device. It generally contains a small amount of tar. In the subsequent ammonia distillation process, the tar in the residual ammonia water is deposited on the trays of the ammonia distillation tower and the heat exchange equipment, which reduces the distillation efficiency and blocks the heat exchange equipment, affecting normal operation and increasing maintenance costs and labor intensity. At present, the residual ammonia water storage tank of the coking plant has a storage function and cannot separate the tar-ammonia water. Summary of the invention

DETAILED DESCRIPTION

[0026] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0027] like Figure 1-8 As shown, a residual ammonia water separation tank includes a tank body 1, a residual ammonia water inlet 2, a tar discharge outlet 3, a residual ammonia water outlet 4, a light tar regulating device 5, a light tar separation baffle 6, a tar ammonia water separation baffle 7, a tar ammonia water separation baffle 8 and a manhole 9.

[0028] The tank body 1 is a vault tank or a cone-top tank. The residual ammonia water inlet 2 is fixedly connected to the lower part of the side wall of the tank body 1 and communicated with the inside of the tank body 1. The residual ammonia water inlet 2 is provided with a horizontally arranged anti-collision plate, which is a semicircular tube and does not affect the tar deposition at the bottom. The manhole 9 is fixedly connected to the top of the tank body 1 and communicated with the inside of the tank body 1. The tar discharge port 3 is fixedly connected to the lowest part of the side wall of the tank body 1 and communicated with the inside of the tank body 1 to facilitate the discharge of tar. The residual ammonia water outlet 4 is fixedly connected to the upper part of the side wall of the tank body 1 and communicated with the inside of the tank body 1.

[0029] The tar-ammonia-water separation baffle 7 is a cylindrical body, which is fixed to the bottom surface of the tank body 1 and has a hole at the residual ammonia water inlet 2 .

[0030] The light tar separation partition 6 is a cylindrical body or a spiral cylindrical body. The light tar separation partition 6 is located on the top of the tar ammonia water separation partition 7. The light tar separation partition 6 includes a bottom plate 11, an ammonia water separation cylinder 12, a light tar separation cylinder 13 and a support plate 14. The bottom plate 11 is fixedly connected to the trough wall of the trough body 1, the ammonia water separation cylinder 12 is fixedly connected to the bottom plate 11, the support plate 14 is fixedly connected to the ammonia water separation cylinder 12, and the light tar separation cylinder 13 is fixedly connected to the support plate 14.

[0031] The tar-ammonia separation baffles 8 are arranged alternately up and down to support the separation partitions. A distance is left above and below the baffles, and a whole connecting plate 10 is arranged at the remaining ammonia inlet 2.

[0032] The light tar regulating device 5 includes a flange 15, a flange cover 16, a seamless steel pipe 17, a cone section 18, a shaft 19, a bolt 20, a nut 21 and a packing 22. The seamless steel pipe 17, the cone section 18 and the shaft 19 are connected in sequence, and the flange 15 and the flange cover 16 are fixed to the seamless steel pipe 17. The bolts 20 and the nuts 21 are installed on the shaft 19, and a sleeve and a handle are provided on the upper part of the shaft 19, and the packing 22 is placed in the sleeve. The density of light tar of each manufacturer is different. The upper handle is adjusted according to the position of the light tar, and the position of the cone section 18 is controlled. When light tar is detected by the discharge liquid through the flange cover 16, the regulating device is fixed; if the position is low and ammonia water is detected, the position of the cone section 18 is adjusted upward to ensure that light tar is detected; if the position is too high, the light tar is discharged with the ammonia water.

[0033] The working principle and working process of the present invention are:

[0034] The remaining ammonia water enters the tank through the residual ammonia water inlet 2 from the bottom of the separation tank through the horizontally arranged anti-collision plate, which does not affect the tar deposition at the bottom. The ammonia water flow rate is reduced, and a gap is left at the bottom of the tar-ammonia water separation baffle 8. The ammonia water flows upward in the tank without affecting the strength of the equipment and the internal partition. A gap is left at the top of the tar-ammonia water separation baffle 8, which does not affect the gas flow at the top and finally fills the tar-ammonia water separation baffle 7. The flow of ammonia water changes the flow direction at the tar-ammonia water separation baffle 8, prolonging the flow time, which is conducive to the separation of tar-ammonia water, and the bottom tar discharge port 3 regularly discharges heavy tar.

[0035] The separated light tar floats on the ammonia water at the light tar separation partition 6, gathers in the light tar separation cylinder 13, and is discharged from the equipment through the light tar regulating device 5; the ammonia water with light and heavy tar removed flows through the ammonia water separation cylinder 12, and is discharged from the equipment through the remaining ammonia water outlet 4 for subsequent processing. The light tar regulating device 5 has the function of regulating the range, and the regulating range is adjusted according to the discharged tar content.

[0036] The invention not only has the storage function, but also can prolong the circulation time and has the effect of separating tar and ammonia water.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
