Description

Technical Field

[0001] This utility model belongs to the technical field of coking production equipment, specifically relating to a drying furnace device applied to a coking chimney. Background Technology

[0002] In the construction of new chemical, power generation, heating, and coking production processes, chimney drying is a crucial step, but traditional drying equipment has some shortcomings. For example, the uneven temperature distribution of existing drying equipment leads to unstable chimney suction, severely affecting the production preparation work of the preceding stages. Moreover, the energy efficiency of existing equipment is low, prolonging the drying time and increasing production costs.

[0003] Traditional hot air burners for ovens are made of high-temperature resistant stainless steel. Considering manufacturing costs and installation difficulties, the burner is only 40cm long, and its length after entering the chimney through the oven hole is even shorter. When hot air is ejected, its effective radiation distance is not very long. This structure increases the oven drying time and costs. If the burner length is set too long, it is difficult to meet the heating requirements of small-diameter ovens. Therefore, whether the burner is long or short, it can only be adapted to a fixed-diameter oven, making it difficult to adjust the burner length and automatically regulate the gas volume. Utility Model Content

[0004] To address the technical problems of uneven temperature distribution and low energy efficiency in existing coking oven equipment, this utility model provides a coking oven equipment with a simple and efficient structure, which improves coke oven quality and reduces production costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coking oven equipment, including a main support, a fan support fixed on the main support, an air supply fan mounted on the fan support, the air supply port of the air supply fan being connected to the air inlet of an air valve group through an air supply pipe, the air outlet of the air valve group being connected to the first air inlet of a mixing valve through a pipe, the air supply status of the entire air supply branch being controlled by the air valve group, and air being supplied to the mixing valve by the air supply fan.

[0006] A gas inlet pipe is fixed on the main support. The gas inlet of the gas inlet pipe is connected to the gas inlet of the gas valve group. The gas outlet of the gas valve group is connected to the gas inlet of the gas flow regulating valve through a pipe. The gas outlet of the gas flow regulating valve is connected to the second gas inlet of the mixing valve through a pipe. The gas supply status of the entire fuel branch is controlled by the gas valve group, and gas is supplied to the mixing valve through the gas inlet pipe.

[0007] The gas supply port of the mixing valve is connected to an adjustable-length burner via a flange. The extension length of the burner is adjusted according to the heating requirements of the oven to control the temperature distribution of the oven and improve energy efficiency.

[0008] Temperature sensors are installed inside the oven.

[0009] The top of the main support is equipped with a control cabinet, which contains an intelligent control system. The intelligent control system is based on a PLC programmable logic controller, receives monitoring signals from temperature sensors and gas flow regulating valves, and automatically adjusts the power of the entire heating device, the fan speed of the gas supply fan, and the opening of the gas flow regulating valve according to the preset oven temperature curve and ventilation parameters.

[0010] The burner consists of multiple sleeves nested together in sequence. The length of the nested sleeves is adjustable. The end of the sleeve with the smallest diameter is connected to an injection pipe. The injection pipe has multiple axial guide holes that communicate with the sleeves along its axis, and multiple radial guide holes that communicate with the corresponding axial guide holes along its radial axis. Hot air enters the chimney through the burner, resulting in a more uniform temperature distribution inside the furnace.

[0011] Multiple axial guide holes placed on the outermost ring are arranged at equal angular intervals around the central axis of the jet pipe, resulting in more uniform air distribution.

[0012] Compared with the prior art, the specific beneficial effects of this utility model are reflected in the following: by arranging a retractable burner, the length of the burner extending into the oven can be adjusted, and multiple guide holes are evenly arranged on the front end of the burner spray pipe, which can better and faster oven drying, thereby saving oven drying time and reducing costs.

[0013] This invention receives temperature monitoring signals and gas flow monitoring signals through a control cabinet. Based on the preset oven temperature curve and ventilation parameters, it automatically adjusts the power of the heating device, the fan speed of the ventilation system, and the opening of the gas flow regulating valve to achieve automated control. This reduces the workload of manual operation and monitoring, lowers the risk of operational errors caused by human factors, and improves production efficiency and product quality stability.

The gas outlet of the gas valve group 8 is connected to the gas inlet of the gas flow regulating valve 9 through a pipe. The gas outlet of the gas flow regulating valve 9 is connected to the second gas inlet 62 of the mixing valve 6 through a pipe. The gas supply status of the entire fuel branch is controlled by the gas valve group 8, and gas is supplied to the mixing valve 6 through the gas inlet pipe 7.

[0022] The gas supply port of the mixing valve 6 is connected to the adjustable burner 10 via a flange. The insertion length of the burner 10 is adjusted according to the heating requirements of the oven to control the temperature distribution of the oven and improve energy utilization efficiency.

[0025] The burner 10 comprises multiple sleeves 101 sequentially nested together. The length of the multiple sleeves 101 is adjustable. The end of the sleeve 101 with the smallest diameter is connected to an injection pipe 102. The injection pipe 102 has multiple axial guide holes 103 that communicate with the sleeves 101 axially, and multiple radial guide holes 104 that communicate with the corresponding axial guide holes 103 radially. Hot air enters the chimney through the burner 10, resulting in a more uniform temperature distribution inside the furnace.

[0028] The intelligent control system inside control cabinet 11 receives signals from temperature sensors and gas flow regulating valve 9. Operators set various parameters for the oven on the human-machine interface, such as oven time ([X] hours), target temperature ([X]℃), and ventilation volume ([X] cubic meters / hour). After setting, the oven equipment is started, and gas is delivered to the oven body through ventilation ducts. Gas flow regulating valve 9 precisely adjusts the ventilation volume according to the control system's instructions to ensure uniform temperature inside the oven.
