Problems solved by technology

Because the volatile matter in the preheating zone of the roasting furnace does not escape uniformly, the temperature rise in the preheating zone of the roasting furnace fluctuates greatly at each stage, and the temperature field is unevenly distributed.
When the temperature in the preheating zone cannot keep up with the set temperature of the process, the current control method can only increase the negative pressure of the flue, increase the amount of hot flue gas from the upstream to heat transfer and increase the temperature, and when the flue gas amount is large, it will dilute the The concentration of volatile matter can easily cause the concentration of volatile matter to be too low to burn, forming a vicious circle
The existing temperature control method in the preheating zone of the roasting furnace not only consumes high energy consumption, but also cannot ensure that the temperature in the preheating zone meets the heating requirements of the process, which directly affects the roasting quality of carbon products

Embodiment 1

[0026] Such as Figure 1-4 As shown, during implementation, the pulse igniter 8 is inserted into the fire wellhead of the corresponding roasting furnace. After the interface is sealed, the ignition and on-off operation of the pulse igniter 8 is controlled according to the instructions of the control device; the image acquisition device 7 is inserted into the upstream of the burner of the corresponding roasting furnace. In the fire well mouth, after the interface is sealed, the volatile matter combustion situation and state image in the fire channel will be collected in real time and transmitted to the control device. After sealing, the temperature and pressure in the fire channel will be collected in real time, and the control device will communicate with the original flame control system through the industrial Ethernet, and the on-site working conditions such as the temperature and pressure of the fire channel and the opening of the smoke exhaust rack valve will be obtained th...

Abstract

The invention relates to a carbon roaster preheating area volatile component monitoring and temperature controlling device and method. On the basis of an existing roaster flame control system, a detecting control device is additionally arranged in a preheating area, the control device comprises a rack which is provided with a cross arm beam frame body, a temperature measuring device, a pressure measuring device and an image collecting device are arranged on the cross arm beam frame body, and a pulse igniter is further arranged on the cross arm beam frame body. Under control of the control device, with a certain negative pressure range, by adjusting the opening degree of an air door of a smoke exhausting frame, the temperature of a flame path is controlled, and when the negative pressure reaches the range limit value, and the temperature in the preheating area does not reach the target value, by means of a self-absorbing type pulse combustor inserted into the flame path and provided with ignition and flame detection, the purpose of setting the temperature curve of the flame path of the preheating area according to the technology for temperature rising can be achieved. The device andthe method have the advantages of accurately analyzing the escape and combustion circumstances of volatile components in the preheating area online in real time, and adjusting the temperature of thepreheating area in time.

Description

technical field [0001] The invention relates to the technical field of carbon roasting, in particular to a device and method for monitoring volatile matter and controlling temperature in a preheating zone of a carbon roasting furnace. Background technique [0002] The heat required to increase the temperature of the carbon block in the preheating zone of the existing roaster is mainly provided by two parts, one part is the flue gas heat brought by the upstream flue gas, and the other part is the heat generated by the combustion of the carbon block itself after the volatile matter escapes. heat. Due to the non-uniform escape of volatile matter in the preheating zone of the roasting furnace, the temperature rises in each stage of the preheating zone of the roasting furnace fluctuate greatly, and the distribution of the temperature field is uneven. When the temperature in the preheating zone cannot keep up with the set temperature of the process, the current control method can...
