Oven temperature control system for coking oven

Abstract

The invention discloses an oven temperature control system for a coking oven, and belongs to the field of temperature control for the chemical industry. The oven temperature control system for the coking oven is used for controlling the oven temperature of the coking oven, comprises a drying coking oven, and also comprises a temperature acquisition device, a control device, automatic regulation valves, a mixer, a mixer blower and a coke oven gas blower, wherein the temperature acquisition device is arranged on the drying coking oven and is connected with the control device through a centralized temperature transmitting device; the control device is connected with the automatic regulation valves; the automatic regulation valves are arranged on pipelines used for connecting the mixer blower and the coke oven gas blower with the mixer respectively; the mixer is connected with the drying coking oven. According to the technical scheme, the drying coking oven can be remotely controlled, and the temperature of the drying coking oven can be regulated; the labor intensity of a technician is alleviated, the problem of higher product rejection rate caused by manual regulation is solved, and the phenomenon of temperature runaway is avoided.

Description

technical field [0001] The invention belongs to the field of temperature control in the chemical industry, and in particular relates to a coking furnace temperature control system. Background technique [0002] In the process of preparing semi-coke from bituminous coal and anthracite, carbonization is required at 600°C to 850°C, making temperature control a key factor in realizing the above-mentioned carbonization and coking process. In the prior art, drying and coking furnaces are usually used to realize the above process, but drying and coking furnaces tend to have problems such as uneven distribution of furnace temperature and fluctuations in product quality, and the control of furnace temperature often requires the experience of technicians If it is carried out, it is easy to cause the coking section of the drying coking furnace to overheat, which is not only labor-intensive but also has a high reject rate of the product, which is easy to cause accidental losses.
