Description

Technical Field

[0001] The utility model relates to the technical field of high borosilicate glass production, and more specifically, to a waste heat treatment device for high borosilicate glass production. Background Art

[0002] High borosilicate glass has good refractory performance and high physical strength. Compared with ordinary glass, it has no toxic side effects, and its mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance and other properties are greatly improved. During the production of high borosilicate glass, a large amount of high-temperature harmful gases with impurities will be generated. If directly discharged, it will cause environmental pollution. Therefore, waste heat treatment equipment will be installed at the exhaust end to cool the exhaust gas.

[0003] However, the existing waste heat treatment equipment generally uses a water-cooling method to cool the exhaust gas, and the waste heat can be recovered. However, due to the single exhaust channel and overly concentrated air flow, when passing through the heat exchange area of the water-cooling area, the heat recovery rate is low, so that the temperature of the exhaust gas is still relatively high when discharged.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Please refer to Figures 1 to 4 , in the present invention, a device for treating waste heat in high borosilicate glass production includes a housing 1. A connection cover 2 is detachably connected to the right side of the housing 1. An intake pipe 3 is fixedly connected to the connection cover 2. A pressure detection component 4 is installed inside the housing 1. An activated carbon adsorption plate 5 is detachably connected to the pressure detection component 4. A diverter 6 is fixedly connected inside the housing 1. A uniformly distributed spiral heat exchange tube 7 is fixedly connected to the left side of the diverter 6. A partition board 8 is fixedly connected inside the housing 1. One end of the spiral heat exchange tube 7 far from the diverter 6 penetrates to the other side of the partition board 8 and is fixedly connected thereto. An exhaust fan 9 is installed on the left side of the housing 1. Cold water diverters 10 are fixedly connected to both the top and bottom of the housing 1. A PLC controller 11 is installed on the top of the housing 1. A buzzer alarm 12 is installed on the PLC controller 11.

[0022] In the present utility model, the housing 1 serves as the main body of the device. The waste gas is introduced through the intake pipe 3 on the right side of the connecting cover 2. The waste gas first passes through the activated carbon adsorption plate 5 for filtration treatment to adsorb harmful particles. Then, the treated high-temperature waste gas enters the shunt member 6 for internal shunting and is respectively guided to the inside of a plurality of spiral heat exchange tubes 7. At this time, inside the space between the shunt member 6 and the partition plate 8, cold water is injected and filled through the cold water guide member 10, and then the cold water continues to flow. At this time, the gas entering the inside of the spiral heat exchange tube 7 undergoes heat exchange through the cold water area to achieve heat energy recovery. And the exhaust fan 9 is started to discharge the cooled waste gas flowing to the left side of the partition plate 8 in the spiral heat exchange tube 7. And as the activated carbon adsorption plate 5 adsorbs particles, the pressure of the waste gas gradually increases. After the pressure detection member 4 detects that the pressure data reaches the set value, at this time, the PLC controller 11 receives the data information of the pressure detection member 4 and controls the buzzer alarm 12 to prompt to replace the activated carbon adsorption plate 5. Thus, the device has the advantages of shunting and cooling the waste gas, increasing the heat exchange contact area, improving the heat recovery efficiency, and having a better effect on reducing the temperature of the waste gas, and solves the problem that in the prior art, generally, the water cooling method is used to cool the waste gas, and the waste heat can be recovered. However, due to the single exhaust passage and the overly concentrated air flow, the heat recovery rate is low when passing through the heat exchange area of the water cooling area, resulting in a still high temperature when the waste gas is discharged.

[0023] Please refer to Figure 1 , wherein: the pressure detection member 4 includes a guide rod 41, a sliding ring 42, a spring 43 and a pressure sensor 44. The guide rod 41 is fixedly installed on the inner wall of the housing 1. The outer side of the sliding ring 42 is slidably connected to the inside of the housing 1. The outer side of the guide rod 41 is slidably connected to the inside of the sliding ring 42. The spring 43 is sleeved on one side of the guide rod 41. One end of the spring 43 is fixedly connected to the inner wall of the housing 1, and the other end of the spring 43 is fixedly connected to the sliding ring 42. The left end of the spring 43 is fixedly connected to the sensing surface of the pressure sensor 44, and the pressure sensor 44 is fixedly installed on the inner wall of the housing 1.

[0024] In the present utility model, as the pressure of the gas passing through the activated carbon adsorption plate 5 gradually increases, it drives the sliding ring 42 to gradually compress the spring 43 along the guide rod 41. The spring 43 transmits the pressure to the pressure sensor 44, and the pressure sensor 44 transmits the detected data to the PLC controller 11 in real time, realizing the real-time monitoring of the working state of the activated carbon adsorption plate 5 and timely replacement.

[0025] Please refer to Figure 1 and Figure 3 , wherein: the shunt member 6 includes a conical cover 61 and a hollow shunt disk 62. The outer side of the wide-mouth end of the conical cover 61 is fixedly connected to the inner wall of the housing 1. The narrow-mouth end of the conical cover 61 is fixedly connected and communicated with the right side of the hollow shunt disk 62. The other side of the hollow shunt disk 62 is fixedly connected and communicated with the spiral heat exchange tube 7.

[0026] In the present utility model, the gas is guided into the interior of the hollow flow dividing disc 62 through the conical cover 61, and then divided into the interiors of a plurality of spiral heat exchange tubes 7, realizing the waste gas diversion, increasing the heat exchange area with external cold water, improving the waste heat recovery efficiency, and achieving more thorough recovery.

[0027] Please refer to Figure 1 and Figure 4 , wherein: the cold water guiding member 10 includes a joint 101 and a horizontal flow dividing pipe 102. One end of the joint 101 is inserted and fixed into the interior of the housing 1, and the top of the horizontal flow dividing pipe 102 is communicated and fixed with the end of the joint 101.

[0028] In the present utility model, by connecting the joint 101 to the external water circuit, cold water can enter the interior of the housing 1 through the joint 101 at the top and then be discharged through the joint 101 at the bottom, realizing continuous flow to recover heat, and the water flow is uniformly introduced through the horizontal flow dividing pipe 102, making the water flow contact the spiral heat exchange tubes 7 more fully.

[0029] Please refer to Figure 1 and Figure 4 , wherein: three water discharge holes 103 are provided on the side of the horizontal flow dividing pipe 102 facing the interior of the housing 1.

[0030] In the present utility model, the water flow is dispersed and discharged through the three water discharge holes 103, making the contact efficiency between the cold water and the spiral heat exchange tubes 7 higher.

[0031] Please refer to Figure 1 , wherein: a control valve 104 is fixedly installed on the outer side of the joint 101.

[0032] In the present utility model, the control valve 104 facilitates controlling the opening and closing of the joint 101 and the flow rate of the cold water.
