The top of the physical purification box is connected to the top of the chemical purification box through a pipe. A filter plate is movably installed inside the physical purification box. The bottom of the physical purification box is connected to the top of the sedimentation chamber through a pipe.

[0004] In the aforementioned patent, although the problem of unsatisfactory waste gas treatment effect is solved by combining physical purification box and chemical purification box, as the reaction proceeds, the effective components in the purification liquid will continuously react chemically with the harmful substances in the waste gas, and its concentration will gradually decrease. When it decreases to a certain level, the removal efficiency of the purification liquid for harmful substances will decrease significantly. If the purification liquid is not replaced in time, it will affect the treatment effect of waste gas. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that, as the reaction proceeds, the effective components in the purification liquid continuously react chemically with the harmful substances in the waste gas, and their concentration gradually decreases. When the concentration decreases to a certain level, the removal efficiency of the purification liquid for harmful substances will significantly decrease, and if the purification liquid is not replaced in time, it will affect the treatment effect of the waste gas. Therefore, this invention proposes a waste gas treatment device for glass ball furnaces.

[0014] 1. In this utility model, the buffer cylinder is connected to the purification box, and the three-way valve is connected to the discharge pipe and the three-way valve respectively. The gas treated by the purification box is sent into the buffer cylinder.

An auxiliary mechanism is provided on one side of the auxiliary cylinder 5. The auxiliary mechanism includes a buffer cylinder 15, an axial flow fan 18, and a three-way valve 21. A purification box 3 is fixedly connected to one end of the buffer cylinder 15. An alarm 17 is fixedly connected to the outer ring surface of the buffer cylinder 15. A gas sensor 16 is electrically connected to the alarm 17. One side of the gas sensor 16 is fixedly connected to the outer ring surface of the buffer cylinder 15, and the end of the gas sensor 16 penetrates through the side wall of the buffer cylinder 15. The other end of the buffer cylinder 15 is connected to the three-way valve 21. A discharge pipe 20 is fixedly connected to one end of the three-way valve 21. A connecting pipe 19 is fixedly connected to the top of the three-way valve 21. One end of the connecting pipe 19 is fixedly connected to the axial flow fan 18. A diversion pipe 14 is fixedly connected to one end of the axial flow fan 18.

[0024] The exhaust pipe 2 guides the exhaust gas into the auxiliary cylinder 5. The treated gas in the auxiliary cylinder 5 is sent into the purification box 3 through the guide pipe 4, allowing the gas to fully react with the purification liquid below the surface of the purification liquid in the purification box 3. The purification box 3 is connected to the buffer cylinder 15, allowing the reacted gas to be sent into the buffer cylinder 15 for buffering and detection. The gas sensor 16 can detect the composition and content of harmful substances in the gas in the buffer cylinder 15, helping to determine whether the current exhaust gas treatment is qualified. The three-way valve 21 can change the flow direction of the gas. The discharge pipe 20 can directly discharge the qualified gas after treatment. The connecting pipe 19 can guide the unqualified gas. The axial flow fan 18 can accelerate the flow of gas between the connecting pipe 19 and the guide pipe 14, allowing the gas to smoothly enter the guide pipe 14.

[0025] Example 2: Figures 1-3 As shown, an auxiliary box 9 is fixedly connected to the top of the purification box 3, a drain pipe is fixedly connected to the bottom of the auxiliary box 9, a diversion pipe 14 penetrates the top of the auxiliary box 9, an exhaust pipe 13 is fixedly connected to the top of the auxiliary box 9, a liquid tank 12 is fixedly connected to the top of the auxiliary box 9, a water pump 11 inlet is fixedly connected to one side of the liquid tank 12, the bottom of the water pump 11 is fixedly connected to the auxiliary box 9, and an annular spray pipe 10 is fixedly connected to the outlet of the water pump 11 after penetrating the top side wall of the auxiliary box 9. The outer ring surface of the annular spray pipe 10 is fixedly connected to the inner wall of the auxiliary box 9. A drain pipe is fixedly connected to the bottom of the purification box 3, an inlet pipe 8 is fixedly connected to one side of the purification box 3, and a guide pipe 4 is fixedly connected to the top of the purification box 3. One end of the guide pipe 4 is fixedly connected to the auxiliary cylinder 5. Two filter screens 7 are bolted to the inner wall of the auxiliary cylinder 5. An adsorption plate 6 is set above the filter screens 7, and the outer ring surface of the adsorption plate 6 is engaged with the inner wall of the auxiliary cylinder 5.

[0026] The purification box 3 provides support for the bottom of the auxiliary box 9, ensuring its stability during use. The guide pipe 14 guides the gas entering the auxiliary box 9. The water pump 11 facilitates the delivery of liquid from the liquid tank 12 into the annular spray pipe 10. The nozzle at the bottom of the annular spray pipe 10 sprays the liquid evenly, facilitating a full reaction between the liquid and the gas, thus treating the gas and reducing the residue of harmful substances. Opening the valve on the exhaust pipe 13 allows the treated gas to be discharged, balancing the internal pressure of the auxiliary box 9. The adsorption plate 6 enables the waste gas to be adsorbed and purified in the auxiliary cylinder 5, achieving preliminary treatment of the waste gas and reducing the consumption of purification liquid in the subsequent purification box 3.

[0027] The operating method and working principle of this device are as follows: First, the waste gas generated from the glass ball processing in furnace 1 is sent into auxiliary cylinder 5 through waste gas pipe 2. After being filtered by filter screen 7 at the bottom of auxiliary cylinder 5, it is then adsorbed and purified by adsorption plate 6 containing activated carbon. The waste gas after preliminary purification can be introduced into the purification tank 3 below the liquid surface through guide pipe 4, reacting with the purification liquid in purification tank 3. The reacted gas enters buffer cylinder 15 through the through-hole on the right side. The waste gas in buffer cylinder 15 is detected by gas sensor 16. If the content of harmful substances is less than the predetermined value, it indicates that the current gas treatment is qualified. The three-way valve 21 is opened by the external controller, connecting buffer cylinder 15 to discharge pipe 20. The gas is discharged through the exhaust pipe 20. When the content of harmful substances is greater than the predetermined value, it indicates that the current waste gas treatment is unqualified and the purification liquid needs to be replaced. At this time, the alarm 17 sounds an alarm to remind the staff. The controller opens the three-way valve 21 to connect the buffer cylinder 15 with the connecting pipe 19. The axial flow fan 18 drives the gas to flow between the connecting pipe 19 and the diversion pipe 14, sending the gas into the bottom of the inner cavity of the auxiliary box 9. The water pump 11 sends the reducing agent or alkaline solution in the liquid tank 12 into the annular spray pipe 10, which is sprayed out through the nozzle at the bottom of the annular spray pipe 10 to react with the waste gas. The gas after the reaction can be discharged through the exhaust pipe 13, and the waste liquid can be discharged from the bottom of the auxiliary box 9.
