Problems solved by technology

This kind of system needs to be specially equipped with a cooling tower, and the investment cost of the equipment is very high. It not only consumes power, but also consumes a lot of water during the cooling process.
In addition, to separately configure the steam boiler to heat and dehydrate the tar in the tar tank, special investment in boilers and power is required, and special boiler workers are required to operate and operate, and consume a large amount of coal or gas or other fuels

Embodiment Construction

[0013] As shown in the accompanying drawings, the present invention mainly arranges a cooling jacket 3 with a sandwich structure under the coke oven, and the cavity in the middle of the cooling jacket 3 communicates with the coke oven and the coke guide port. The water outlet of the cooling jacket 3 is connected with the water delivery pipe 5, and the other end of the water delivery pipe 5 is connected with the heating pipeline of the dehydration tank 4 and the tar tank 1 again. The return pipe 6 from the dehydration tank 4 and the tar tank 1 is connected to the circulating water tank 2, and the output pipe of the circulating water tank 2 is communicated with the water inlet of the cooling jacket 3 through a circulating water pump 7 to form a closed loop system.

[0014] In actual operation, the circulating water pump 7 sends the water in the circulating water tank 2 to the cooling jacket 3, and the high-temperature semi-coke falling from the coke oven will exchange heat with t...

Abstract

The invention discloses a low-temperature carbonization coke oven hot-water circulation use system. A cooling water jacket is connected below the coke oven for the heat exchange with a fervent semicoke. The system is characterized in that the hot water discharged from a cooling jacket (3) is delivered to a dehydrating tank (4) and a tar tank (1) for heating via a water delivery pipe (5), and is then delivered to a circulation water tank (2) via a water returning pipe (6) to be discharged back to the cooling jacket for recycling. A circulation waster pump (7) is mounted on the water returning pipe between the cooling jacket and the circulation water tank. The system sufficiently utilizes the heat of the discharged semicoke for the heat exchange with the circulation water within the cooling jacket so that the heated circulation water is directly delivered to heating pipelines of the dehydrating tank and the tar tank to play a role of heating. The system does not need a cooling tower and a steam boiler, only uses extremely little power as well as has simple equipments, low running costs, no waste exhaust and the heat energy that can be recycled.

Description

technical field [0001] The invention relates to a low-temperature dry distillation coke oven hot water recycling system. Background technique [0002] For the production of semi-coke in low-temperature carbonization coke ovens, the temperature of semi-coke discharged from the coke oven can reach above 600°C, and a water-cooled jacketed coke discharge box is installed at the bottom of the furnace to ensure that the steel structure at the bottom of the furnace is not damaged by heat. After the circulating water in the jacket of the coke discharge box is discharged, it needs to be cooled by the cooling tower before it can be recycled. This kind of system needs to be specially equipped with a cooling tower, and the equipment investment cost is very high. Not only does it need to consume power, it also needs to consume a large amount of water during the cooling process. In addition, to separately configure the steam boiler to heat and dehydrate the tar in the tar tank, special i...
