Problems solved by technology

[0003] In order to solve the current situation that the semi-coke heat of the traditional retort furnace cannot be directly recovered, reduce the heat consumption of the retort process, improve the efficiency of energy use, protect the environment and ensure production safety, this invention provides a new device for recovering the semi-coke heat discharged from the retort furnace. It is characterized in that: a cold gas injection device consisting of a flower wall, a cold gas channel and a cold gas injection hole is installed at the bottom of the retort furnace to spray cold gas at 35°C to 45°C, so that the temperature of the semi-coke discharged from the retort furnace is from 500°C to 550°C ℃ is reduced to 250 ℃ ~ 300 ℃, the recovered heat is directly used to supplement the heat required for carbonization, reducing the heat consumption of carbonization furnace

Embodiment Construction

[0010] attached figure 1 Provided is the structure and connection diagram of the cold gas injection device of the present invention. It is characterized in that a plurality of upright hollow flower walls 2 are arranged at the lower part of the retort furnace, coke discharge channels 5 are formed between the two flower walls, the hollow part of the flower walls 2 is a cold gas channel 3, and two sides of the flower walls 2 are opened The cold gas injection hole 4; the outside of the cold gas channel 3 is connected in sequence with the cold gas inlet pipe 9, the cold gas connecting pipe 10, the gas blower 11, and the gas cabinet 12, and the dry distillation oil and gas discharge pipe 13 is arranged on the upper part of the dry distillation furnace.

[0011] When the carbonization furnace is in operation, the cold gas that has been cooled to 35°C to 45°C in the gas cabinet 12 is sent into the cold gas channel 3 through the gas fan 11 through the cold gas connection pipe 10 and th...

Abstract

The invention relates to a device arranged in a carbonization furnace for recovering carbocoal heat discharged from the carbonization furnace. The device is characterized in that a cold gas jetting device consisting of lattice walls, cold gas passages and cold gas jetting holes is arranged at the bottom of the carbonization furnace. Cold gas at the temperature of 35-45 DEG C is jetted, so that the temperature of the carbocoal heat discharged from the carbonization furnace is reduced from 500-550 DEG C to 250-300 DEG C recovered heat is used for complementing heat required for carbonization, and heat consumption of the carbonization furnace is reduced.

Description

technical field [0001] The present invention is a process and device for recovering the heat of semi-coke discharged from the retort furnace. °C, the recovered heat is used to supplement the heat required for carbonization and reduce the heat consumption of carbonization furnace. Background technique [0002] At present, the traditional retort furnaces in China do not recover the physical sensible heat contained in the semi-coke after carbonization, and directly discharge the semi-coke into the pool, cool it with water, and then send the semi-coke to the storage yard. Generally, the temperature of the semi-coke after dry distillation is about 550°C, and the enthalpy contained in it is 13.5×10 4 kcal / t, equivalent to more than half of the heat consumed by the entire dry distillation process. This process not only causes a waste of energy, but also increases the load on heating equipment, resulting in increased investment and operating costs. The main reasons why the heat o...
