Description

Technical Field

[0001] This utility model relates to the field of purification tower technology, and in particular to a quantitative slag discharge water circulation device for a silane combustion purification tower. Background Technology

[0002] Silane combustion purification towers are commonly used in waste treatment systems. They utilize the reaction products of air and silane under high temperature and pressure as an absorbent to decompose harmful components in waste gas into carbon dioxide and nitrogen, thereby reducing pollutant emissions. The process typically involves a series of multi-stage scrubbing towers, including acid / alkali washing and tail gas condensation. This serves two purposes: firstly, to balance the acidity or alkalinity of the emitted flue gas to achieve neutral emissions; and secondly, to reduce the moisture content in the flue gas through condensation, thereby reducing the total amount of emissions and eliminating whitening. In the acid / alkali washing purification process, silane combustion purification towers typically use water spraying to remove particulate matter and harmful gases from flue gas. The purified flue gas is then atomized and sprayed with a purification liquid that needs to be recycled to ensure the purification rate. For example, Chinese patent document CN202021010380.4 discloses a water circulation system for a spray purification tower, which includes a purification tower. Two air inlets are opened on one inner wall of the purification tower, and air inlet pipes are welded and fixed in each air inlet. The two air inlet pipes pass through the corresponding air inlets, and their ends are connected. Two mounting holes are opened on the inner wall of the purification tower away from the air inlets, and branch pipes are welded and fixed in each mounting hole. The two branch pipes pass through the corresponding mounting holes. A water outlet pipe is provided in the purification tower and passes through the purification tower. A water pump is welded and fixed on the side of the purification tower near the branch pipes. The water pump has an inlet end and an outlet end, and the end of the outlet pipe near the water pump is welded and fixed together with the inlet end. The aforementioned patent enables the recycling of purified water, thereby saving a significant amount of water resources. However, in actual use, after water comes into contact with flue gas, it adsorbs and settles particulate matter from the flue gas to the bottom of the pool, forming sludge. Over time, the sludge accumulates and clogs the filter pipes, affecting water circulation. When shutting down for cleaning, the entire filter device needs to be replaced, resulting in high production costs and reduced processing efficiency.

[0003] Therefore, it is necessary for those skilled in the art to provide a quantitative sludge discharge water circulation device for a silane combustion purification tower, which discharges sludge in a fixed manner through a fixed pipeline at regular intervals and in a fixed quantity, thereby reducing sludge accumulation, ensuring the stability of water circulation, and improving the service life of the filter element. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative sludge discharge and water circulation device for a silane combustion purification tower, in order to solve the technical problem that silt accumulates at the bottom of the existing silane combustion purification tower after a long period of time, causing filter element failure and affecting the flow of purification liquid.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a quantitative slag discharge water circulation device for a silane combustion purification tower, including a water tower and a gas tower.

A one-way valve is provided on the end of the slag discharge pipe away from the bottom wall of the water tower. The slag discharge pipe has an internally hollow cylindrical structure. A receiving cavity is formed inside the slag discharge pipe. The receiving cavity is connected to the internal cavity of the filter pipe.

[0006] Furthermore, the gas tower has a hollow cylindrical structure with an internal air filter layer inside. The air filter layer is horizontally arranged in the internal cavity of the gas tower and divides the internal cavity of the gas tower into an upper cavity and a lower cavity.

[0007] Furthermore, the gas tower has an air inlet pipe on its side wall. The air inlet pipe is tubular and connects to the interior of the gas tower. The air filter layer is located above the air inlet pipe. The top of the gas tower has an exhaust port that penetrates the gas tower wall and connects to the upper cavity.

[0008] Furthermore, the drain outlet penetrates the water tower wall and connects to the filter cavity on the water tower, and the lower cavity is connected to the filter cavity through the drain outlet.

[0009] Furthermore, the slag discharge pipe is installed on the bottom wall of the water tower and is coaxially arranged inside the filter pipe.

[0010] Furthermore, the filter pipe is made of glass fiber, and the filter pore size of the filter pipe is 100-500 μm.

[0014] Furthermore, the nozzle located in the lower cavity is connected to the first infusion pipe, and a water pump is provided at the end of the first infusion pipe located in the filter cavity.

[0015] The beneficial effects of this invention are as follows: This invention provides a cavity for the sludge through a sludge discharge pipe, preventing the sludge from accumulating in the filter pipe for extended periods, thus preventing clogging of the filter channel and ensuring the filtration effect of this invention. Simultaneously, operators can selectively set the size of the cavity or the opening time of the one-way valve to control the amount of sludge. When the sludge reaches a fixed amount, the one-way valve is activated to discharge the sludge from the cavity, ensuring filtration stability and achieving quantitative sludge discharge.

[0021] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Please see Figure 1 , Figure 2This utility model provides a quantitative slag discharge water circulation device for a silane combustion purification tower, including a water tower 10 and a gas tower 20. The water tower 10 is located below and connected to the gas tower 20. The water tower 10 and the gas tower 20 can be detachably connected as a single unit to reduce the overall size of the equipment. The water tower 10 is filled with a purification liquid, which includes, but is not limited to, lime slurry and alkaline solution, to balance the acidic substances in the emitted flue gas and achieve neutral emission requirements. The gas tower 20 has an air inlet pipe 25 on its side wall. The air inlet pipe 25 is tubular and connects to the interior of the gas tower 20. The gas tower 20 is also connected to an incinerator (not shown) through the air inlet pipe 25. The exhaust gas generated after combustion in the incinerator is introduced into the gas tower 20. The exhaust gas includes substances such as sulfur dioxide, nitrogen oxides, and heavy metals. The purification liquid in the water tower 10 neutralizes and purifies the exhaust gas in the gas tower 20, reducing harmful and toxic gases and ensuring the safety of the emitted gas.

[0023] Further, please refer to Figure 3 , Figure 4 The gas tower 20 has a hollow cylindrical structure. An air filter layer 29 is installed inside the gas tower 20 to filter the gas. The air filter layer 29 is horizontally arranged within the internal cavity of the gas tower 20, dividing the internal cavity into an upper cavity 22 and a lower cavity 23. The air filter layer 29 is located above the air inlet pipe 25. An exhaust port 28 is provided at the top of the gas tower 20, penetrating the wall of the gas tower 20 and connecting to the upper cavity 22. Preferably, the air filter layer 29 is made of activated carbon filter mesh. A nozzle 17 is provided on the surface of the air filter layer 29 facing the lower cavity 23. The nozzle 17 is connected to a purification liquid and is used to atomize and spray the purification liquid into the lower cavity 23 to purify the waste gas.

[0024] In use, exhaust gas is introduced into the lower cavity 23 through the inlet pipe 25 and undergoes neutralization and purification treatment within the lower cavity 23. Particulate matter in the exhaust gas mixes with the purified liquid to form a mixture. Simultaneously, the treated gas passes through the air filter layer 29 into the upper cavity 22 and is discharged from the exhaust port 28, completing the exhaust process. The air filter layer 29, made of activated carbon filter mesh, blocks and filters out particulate matter in the exhaust gas, allowing the exhaust gas to remain in the lower cavity 23 for an extended period. This facilitates subsequent purification processes and ensures the safety of gas discharge. Simultaneously, the activated carbon filter mesh also adsorbs moisture, reducing the moisture content in the gas discharged from the exhaust port 28, decreasing the total emissions, and improving operational stability.

[0025] Please refer to it again. Figure 3 , Figure 4The water tower 10 has a hollow, square shell structure with a filter cavity 15 inside. The purified liquid fills the filter cavity 15. A drain port 11 is provided on the top surface of the water tower 10 at the lower cavity 23. The drain port 11 penetrates the wall of the water tower 10 and connects to the filter cavity 15 on the water tower 10. At the same time, the lower cavity 23 is connected to the filter cavity 15 through the drain port 11.

[0026] A filter pipe 12 is installed inside the water tower 10 at the drain outlet 11. The filter pipe 12 is coaxially arranged outside the drain outlet 11, extending from the top wall of the water tower 10 downwards to the bottom wall, thereby isolating the filter cavity 15 from the drain outlet 11 to ensure filtration. In this embodiment, the filter pipe 12 is made of glass fiber, and the pore size of the filter pipe 12 is 100-500 μm, ensuring filtration effect. A flow-damping plate 13 is also provided inside the drain outlet 11. The flow-damping plate 13 is made of plastic and has through holes. This ensures that the mixed liquid in the lower cavity 23 flows evenly into the filter cavity 15 at a fixed speed, ensuring stable filtration.

[0027] In use, the mixture flows from the gas tower 20 into the water tower 10. The mixture passes through the slow-flow plate 13 and the filter pipe 12 in the drain port 11 in sequence, and finally accumulates at the bottom of the water tower 10. The mixture is filtered through the filter pipe 12 to obtain filtrate. The filtrate enters the filter cavity 15 through the filter pipe 12. The sludge in the mixture is filtered and deposited inside the filter pipe 12.

[0028] Please refer to it again. Figure 3 The bottom wall of the water tower 10 is provided with a sludge discharge pipe 18. One end of the sludge discharge pipe 18 penetrates the bottom wall of the water tower 10 and extends into the interior of the filter pipe 12. The other end of the sludge discharge pipe 18 extends away from the bottom wall of the water tower 10. The sludge discharge pipe 18 is coaxially arranged in the filter pipe 12. A one-way valve 19 is provided at the end of the sludge discharge pipe 18 away from the bottom wall of the water tower 10. Preferably, the one-way valve 19 includes, but is not limited to, an electromagnetic one-way valve. The one-way valve 19 is used to control the opening and closing of the sludge discharge pipe 18 to realize the discharge of sludge deposited in the filter pipe 12.

[0029] In this embodiment, the sludge discharge pipe 18 is installed on the bottom wall of the water tower 10. The sludge discharge pipe 18 has a hollow cylindrical tube structure, and a receiving cavity 21 is formed inside the sludge discharge pipe 18. The receiving cavity 21 is connected to the internal cavity of the filter pipe 12, so that the sludge deposited in the filter pipe 12 can flow into the receiving cavity 21. This utility model provides a receiving cavity 21 for the sludge through the sludge discharge pipe 18, so that the sludge will not accumulate in the filter pipe 12 for a long time, thereby preventing the filter channel from being blocked and ensuring the filtration effect of this utility model. At the same time, the operator can selectively set the size of the receiving cavity 21 or the opening time of the one-way valve 19 to control the amount of sludge. When the sludge reaches a fixed amount, the one-way valve 19 is activated to discharge the sludge in the receiving cavity 21, ensuring filtration stability and achieving quantitative sludge discharge.

[0030] Please see Figure 3 A first infusion pipe 14 is provided between the water tower 10 and the gas tower 20. One end of the first infusion pipe 14 penetrates the wall of the water tower 10 and extends into the filter cavity 15, and the other end of the first infusion pipe 14 penetrates the wall of the gas tower 20 and extends into the lower cavity 23.

[0031] In this embodiment, the nozzle 17 located in the lower cavity 23 is connected to the first infusion pipe 14. A water pump 16 is installed at the end of the first infusion pipe 14 located in the filtration cavity 15. The water pump 16 is used to pump the filtrate in the filtration cavity 15 from the first infusion pipe 14 into the nozzle 17, thus achieving the feeding and spraying of the purified liquid. This invention achieves the reuse of the purified liquid by filtering it after purification, thereby reducing the use of replenishing liquid, improving resource utilization, and saving water.

[0032] In this embodiment, a triangular support 24 is provided inside the filter cavity 15. Multiple triangular supports 24 are provided and evenly arranged around the filter pipe 12. One end of the triangular support 24 is fixedly connected to the outer wall of the filter pipe 12, and the other end of the triangular support 24 is fixedly connected to the bottom wall of the filter cavity 15, thereby ensuring the stability of the filter pipe 12 in use.

[0033] The specific operation method of this utility model is as follows: Step 1: The exhaust gas is introduced into the lower cavity 23 through the air inlet pipe 25 and neutralized and purified in the lower cavity 23. The particulate matter in the exhaust gas is mixed with the purification liquid to obtain a mixed liquid. At the same time, the gas after treatment enters the upper cavity 22 through the air filter layer 29 and is discharged from the exhaust port 28 to complete the exhaust.

[0034] Step 2: The mixture flows from the gas tower 20 into the water tower 10. The mixture passes through the slow flow plate 13 and the filter pipe 12 in the drain port 11 in sequence. The filter pipe 12 filters the mixture to obtain filtrate. The filtrate enters the filter cavity 15. The sludge in the mixture is filtered by the filter pipe 12 and deposited into the receiving cavity 21.

[0035] Step 3: The water pump 16 introduces the filtrate in the filtration cavity 15 into the nozzle 17 through the first infusion pipe 14, thereby realizing the feeding and spraying of the purified liquid.

[0036] Step 4: When the sludge reaches a fixed amount, activate the one-way valve 19 to discharge the sludge from the cavity 21, thus achieving quantitative sludge discharge.

[0037] This invention provides a cavity 21 for the sludge through a sludge discharge pipe 18, preventing the sludge from accumulating in the filter pipe 12 for extended periods, thus preventing clogging of the filter channel and ensuring the filtration effect of this invention. Simultaneously, operators can selectively set the size of the cavity 21 or the opening time of the one-way valve 19 to control the amount of sludge. When the sludge reaches a fixed amount, the one-way valve 19 is activated to discharge the sludge from the cavity 21, ensuring filtration stability and achieving quantitative sludge discharge.
