However, the traditional internal heating rotary activation furnace has some limitations and problems. The existing internal heating rotary activation furnace has some shortcomings in mixing steam.

[0003] The traditional method is to set a pipe in the center of the activation furnace, and then divide several pipe outlets from the central pipe, and the water vapor is sprayed around the furnace cavity.

[0025] The gas nozzle 101 is divided into multiple spray blocks in the horizontal direction. On each spray area cross section, it is divided into multiple spray areas along the center of the cross section of the furnace body 100. The spray blocks and spray areas can be divided evenly or according to other specified rules. No specific requirements are made here.

When the material in the furnace body 100 is activated, the control device controls the gas nozzles 101 in different spray blocks and different spray areas to spray water vapor or air according to the location of the material, so as to enable the material activation to proceed normally.

[0028] N pressure testing devices are provided on the inner wall of the furnace body 100 near the furnace tail end, and the pressure testing devices are used to monitor the pressure data in the furnace body 100 near the furnace tail end.

The control device adjusts the suction force of the flue induced draft fan according to the pressure data to ensure that the pressure in the furnace body 100 is 50-120pa, thereby avoiding the furnace tail end of the furnace body 100 due to excessive pressure, causing the combustible gas to leak out and burn the discharge device, or due to the furnace tail end of the furnace body 100 due to too low pressure, causing the air (oxygen) to be sucked into the gap at the furnace tail end, causing local overheating, oxidation and burning, and white material to appear, reducing product quality. The control device can also simulate and display the conditions inside and outside the furnace tail according to the pressure data, so as to timely discover abnormal furnace pressure.

[0029] The control device includes a calculation and analysis unit, a command generation unit, an animation production unit and a display unit. The calculation and analysis unit calculates the real-time pressure value in the furnace body 100 at the furnace tail end according to the pressure data monitored in real time by N pressure testing devices. The command generation unit determines the required induced draft pressure according to the real-time pressure value in the furnace body 100 at the furnace tail end, and generates a corresponding control command for the furnace tail induced draft device 102 to adjust the induced draft power of the furnace tail induced draft device 102. The animation production unit generates a simulated animation of the inside and outside of the furnace body 100 at the furnace tail end according to the real-time pressure value in the furnace body 100 at the furnace tail end, and sends the simulated animation to the display unit for display.

[0030] The control device further comprises a storage device and an input device, wherein the storage unit stores an original model of the simulated animation, and the input device can update the original model of the simulated animation.

The twin simulation model can be input through the input unit and stored in the storage unit. The calculation and analysis unit calls the twin simulation model from the storage unit.

[0033] The computing and analysis unit uses a twin simulation model to obtain real-time pressure data sets in N pressure test devices, such as Figure 2 As shown, the specific process includes: First, the calculation and analysis unit obtains the operation data of the furnace shaft 100, and imports the operation data of the furnace shaft 100 into the twin simulation model.

[0034] Secondly, the calculation and analysis unit calculates the real-time material pressure of each pressure testing device covered by the material based on the highest position of the material in the twin simulation model and the position of each pressure testing device covered by the material by decomposing the material pressure.

[0035] Finally, the calculation and analysis unit selects the pressure testing device without material pressure in the furnace body 100 in real time according to the highest position of the material in the twin simulation model, and reads the real-time pressure data of the pressure testing device without material pressure; the calculation and analysis unit calculates the real-time gas pressure of each pressure testing device covered by material according to the real-time pressure data of each pressure testing device covered by material and the material pressure corresponding to the real-time pressure data of each pressure testing device covered by material; the real-time pressure data of the pressure testing device without material pressure and the real-time gas pressure of each pressure testing device covered by material constitute a real-time pressure data set.

[0036] The calculation and analysis unit calculates the real-time pressure value in the furnace body 100 at the furnace tail end. Specifically, the calculation and analysis unit calculates the real-time pressure value by averaging the pressure data in the real-time pressure data set.

[0037] The storage unit also stores a pressure induced draft adjustment reference table, which includes required induced draft powers corresponding to different furnace internal pressures.

[0038] The command generating unit searches for the corresponding required induced draft power in the pressure induced draft condition reference table according to the real-time pressure value. At the same time, the control device obtains the current induced draft power of the furnace tail draft device 102. Then, the command generating unit generates an adjustment command for the induced draft device according to the required induced draft power of the real-time pressure value and the current induced draft power of the furnace tail draft device 102, and then sends the adjustment command to the furnace tail draft device 102 to adjust the induced draft power of the furnace tail draft device 102.

[0039] The original model of the simulated animation stored in the storage unit, ie, the basic animation mask, may be a visible light image of the activation furnace, or an image outlined according to the activation furnace, and no specific requirements are made here.

[0040] The simulated animation includes a basic animation mask and an adjustment animation mask, and the adjustment animation mask covers the surface of the basic animation mask. The adjustment animation mask is a perspective mask, that is, the content-free part of the adjustment animation mask is a transparent structure. When the basic animation mask is located in the image-free part of the adjustment animation mask, the content of the adjustment animation mask and the basic animation mask is displayed in combination through the adjustment animation mask. When the basic animation mask is located in the image-free part of the adjustment animation mask, the content of the adjustment animation mask and the basic animation mask is displayed in combination through the adjustment animation mask. The adjustment animation mask includes an inhalation animation mask and a leakage animation mask, and the basic animation mask, the inhalation animation mask and the leakage animation mask constitute the simulated animation.

[0041] The suction animation mask includes a suction areas, and the a suction areas are centered at the furnace tail end of the furnace body 100 and spread in a direction away from the furnace body 100 in sequence, that is, in two adjacent suction areas, the outer circle diameter of the suction area close to the furnace body 100 is equal to the inner circle diameter of the suction area away from the furnace body 100. Each suction area includes a simulated airflow and a suction amount schematic mark, and the transparency of each suction area can be adjusted according to the real-time pressure value.

[0042] The leakage animation mask includes b leakage areas, and the b leakage areas are centered at the furnace tail end of the furnace body 100 and spread in a direction away from the furnace body 100 in sequence, that is, in two adjacent leakage areas, the outer circle diameter of the leakage area close to the furnace body 100 is equal to the inner circle diameter of the leakage area away from the furnace body 100. Each leakage area includes a simulated flame and a schematic mark of leakage amount, and the transparency of each leakage area can be adjusted according to the real-time pressure value.

[0043] a and b are both positive integers greater than 1.

[0044] The adjustment animation mask adjusts transparency according to the difference between the real-time pressure value and the first specified value or the second specified value, so that the simulation animation can achieve the purpose of graded alert according to different real-time pressure values.

[0045] For example: When the difference between the real-time pressure value and the first specified value is greater than or equal to the first suction difference, the transparency of the suction area is 100%. At this time, the suction area is completely transparent, that is, the suction animation mask is not displayed in the simulated animation; when the difference between the real-time pressure value and the first specified value is less than the first suction difference and greater than or equal to the second suction difference, the transparency of the suction area is 75%; when the difference between the real-time pressure value and the first specified value is less than the second suction difference and greater than or equal to the third suction difference, the transparency of the suction area is 50%; when the difference between the real-time pressure value and the first specified value is less than the third suction difference and greater than or equal to the fourth suction difference, the transparency of the suction area is 25%; when the difference between the real-time pressure value and the first specified value is less than the fourth suction difference, the transparency of the suction area is 0%. At this time, the suction area completely covers the basic animation mask.

[0046] When the difference between the real-time pressure value and the second specified value is less than or equal to the first leakage difference, the transparency of the leakage area is 100%. At this time, the leakage area is completely transparent, that is, the leakage animation mask is not displayed in the simulated animation; when the difference between the real-time pressure value and the second specified value is greater than the first leakage difference and less than or equal to the second leakage difference, the transparency of the leakage area is 75%; when the difference between the real-time pressure value and the second specified value is greater than the second leakage difference and less than or equal to the third leakage difference, the transparency of the leakage area is 50%; when the difference between the real-time pressure value and the second specified value is greater than the third leakage difference and less than or equal to the fourth leakage difference, the transparency of the leakage area is 25%; when the difference between the real-time pressure value and the second specified value is greater than the fourth leakage difference, the transparency of the leakage area is 0%. At this time, the leakage area completely covers the basic animation mask.

[0047] The first designated value is the minimum value of the pressure range that the furnace can withstand, and can be input or modified through the input device. The second designated value is the maximum value of the pressure range that the furnace can withstand, and can be input or modified through the input device.

[0048] The first suction difference>the second suction difference>the third suction difference>the fourth suction difference, and the first suction difference is preferably 0. The first leakage difference<the second leakage difference<the third leakage difference<the fourth leakage difference, and the first leakage difference is preferably 0.

[0049] The adjustment animation mask is displayed by flashing according to the real-time pressure value. Specifically, the flashing frequency of the adjustment animation mask is adjusted according to the difference between the real-time pressure value and the first specified value or the second specified value. By adjusting the flashing frequency of the animation mask, the purpose of graded alert is achieved.

[0050] For example: When the difference between the real-time pressure value and the first designated value is greater than or equal to the first suction difference, the flashing frequency of the suction area is 2 times / min, and the display time is 5 seconds each time; when the difference between the real-time pressure value and the first designated value is less than the first suction difference and greater than or equal to the second suction difference, the flashing frequency of the suction area is 4 times / min, and the display time is 5 seconds each time; when the difference between the real-time pressure value and the first designated value is less than the second suction difference and greater than or equal to the third suction difference, the flashing frequency of the suction area is 6 times / min, and the display time is 5 seconds each time; when the difference between the real-time pressure value and the first designated value is less than the third suction difference and greater than or equal to the fourth suction difference, the flashing frequency of the suction area is 9 times / min, and the display time is 5 seconds each time; when the difference between the real-time pressure value and the first designated value is less than the fourth suction difference, the flashing frequency of the suction area is 12 times / min, and the display time is 5 seconds each time. At this time, the effective display time of the suction area is 60 seconds.

[0051] When the difference between the real-time pressure value and the second specified value is less than or equal to the first leakage difference, the flashing frequency of the leakage area is 2 times / min, and the display time is 5 seconds each time; when the difference between the real-time pressure value and the second specified value is greater than the first leakage difference and less than or equal to the second leakage difference, the flashing frequency of the leakage area is 4 times / min, and the display time is 5 seconds each time; when the difference between the real-time pressure value and the second specified value is greater than the second leakage difference and less than or equal to the third leakage difference, the flashing frequency of the leakage area is 6 times / min, and the display time is 5 seconds each time; when the difference between the real-time pressure value and the second specified value is greater than the third leakage difference and less than or equal to the fourth leakage difference, the flashing frequency of the leakage area is 9 times / min, and the display time is 5 seconds each time; when the difference between the real-time pressure value and the second specified value is greater than the fourth leakage difference, the flashing frequency of the leakage area is 12 times / min, and the display time is 5 seconds each time. At this time, the effective display time of the leakage area is 60 seconds.
