[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This ceramsite production waste gas and wastewater purification and recovery equipment, through its shell, baffle plate, waste gas pipe, waste water pipe, reaction vessel, and filter screen structure, allows users to perform preliminary filtration of waste gas through wastewater during operation, eliminating the need for clean water resources and achieving gas-solid separation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5 A waste gas and wastewater purification and recovery device for ceramsite production includes a shell 1, a baffle plate 2 on the inner wall of the shell 1, a sealing layer 13 fixedly installed on the outer wall of the baffle plate 2, a waste gas pipe 3 and a wastewater pipe 4 passing through the top of the shell 1, a reaction vessel 5 and a pressurizing fan 6 fixedly installed on the top of the shell 1, an exhaust pipe 7 passing through the top of the reaction vessel 5, an exhaust pipe 8 at the outlet of the reaction vessel 5, a drain pipe 9 fixedly installed at the end of the shell 1 away from the waste gas pipe 3, a liquid level sensor 10 fixedly installed on the inner wall of the shell 1, and a liquid level sensor 10 installed on the top of the inner wall of the reaction vessel 5. A high-temperature heating rod 11 is provided. A pressure relief shell 12 penetrates the outer wall of the reaction vessel 5. A crossbar 16 is fixedly installed on the inner wall of the pressure relief shell 12. A return spring 17 is sleeved on the outer wall of the crossbar 16. A moving ring 18 is abutted at the end of the return spring 17 near the reaction vessel 5. A connecting rod 19 is fixedly installed on the outer wall of the moving ring 18. A sealing plug 20 is fixedly installed at the end of the connecting rod 19. A pressure relief shell 15 is slidably connected to the outer wall of the sealing plug 20. An activated carbon layer 14 is filled at the bottom of the inner wall of the shell 1. A filter screen 21 is tightly attached to the top of the activated carbon layer 14.
[0022] In the above structure, the configuration of the shell 1, baffle 2, exhaust gas pipe 3, wastewater pipe 4, reaction vessel 5, pressurizing fan 6, liquid level sensor 10, high-temperature heating rod 11, sealing layer 13, activated carbon layer 14, and filter screen 21 allows the user to directly discharge exhaust gas into the shell 1 through the exhaust gas pipe 3 during operation. At this time, the exhaust gas entry point is below the liquid surface, so the wastewater will filter the particulate matter in the exhaust gas, while the exhaust gas flows upward in the form of bubbles that do not dissolve in water. Thus, the exhaust gas is discharged into the reaction vessel 5 by the pressurizing fan 6. The heating effect of the high-temperature heating rod 11 and the alkalinity of sodium hydroxide produce a chemical reaction with the sulfur dioxide in the exhaust gas. After the exhaust gas is treated, the user can remove the baffle 2, allowing the wastewater to be purified by the filtration effect of the filter screen 21 and activated carbon layer 14, as well as by the gelling agent and extractant added by the user through the feeding port. This achieves the effect of treating both exhaust gas and wastewater.
[0023] In a preferred embodiment: the outer wall of the housing 1 is provided with an elongated groove, and the inner wall of the elongated groove is slidably connected to the outer wall of the sealing layer 13, which is made of heat-resistant paint.
[0024] In the above structure, through the set long groove and sealing layer 13 structure, after the user has finished treating the exhaust gas, the pressure relief shell 12 can be directly pulled out, thereby eliminating the blocking effect of the sealing layer 13 on the wastewater. In this way, the filter screen 21 and activated carbon layer 14 are used to filter the wastewater, while the exhaust pipe 8 heats the wastewater. With the help of gelling agent and extractant, the wastewater purification operation can be completed, which makes it convenient for the user to operate.
[0025] In a preferred embodiment: the pressurizing blower 6 is connected to the interior of the reaction vessel 5 through the exhaust pipe 7, the outer wall of the pressure relief shell 15 is provided with a sealing groove, the inner wall of the sealing groove is tightly fitted with the outer wall of the sealing plug 20, and the two are slidably connected. After the sealing plug 20 moves 3cm toward the pressure relief shell 15, the interior of the exhaust pipe 8 is connected to the interior of the reaction vessel 5.
[0026] In the above structure, through the sealing groove and sealing plug 20, when the temperature inside the reaction vessel 5 rises sharply due to the heating effect of the high-temperature heating rod 11, the air pressure increases, causing the sealing plug 20 to be pushed, thereby driving the moving ring 18 to compress the return spring 17. At this time, the interior of the pressure relief shell 15 is connected to the interior of the reaction vessel 5, and hot air enters the interior of the shell 1 through the exhaust pipe 8. By utilizing the characteristic of the exhaust pipe 8 being immersed in wastewater, the wastewater is heated for extraction. This not only effectively reduces the risk of explosion of the reaction vessel 5 and improves the safety of the equipment, but also allows for the recovery and utilization of heat energy, thereby improving the energy utilization rate of the equipment. The heat extraction method also enhances the purification effect of the equipment on wastewater.
[0027] In a preferred embodiment: wastewater is filled between the shell 1 and the sealing layer 13, and the exhaust pipe 8 is immersed in the wastewater; the inner wall of the reaction vessel 5 is filled with sodium hydroxide solution.
[0028] In the above structure, sodium hydroxide has alkaline properties and can react chemically with sulfur dioxide in the waste gas under high temperature conditions. This reaction causes the sulfur dioxide in the waste gas to react with sodium hydroxide to produce sodium sulfite, thereby removing harmful substances from the waste gas and purifying it.
[0029] In a preferred embodiment: the top of the housing 1 is provided with a feeding port, and the distance between the liquid level sensor 10 and the wastewater surface is 5cm.
[0030] In the above structure, through the feeding port structure, when the user discharges wastewater into the housing 1 through the wastewater pipe 4, the liquid level sensor 10 will sense the liquid level. After the exhaust gas is initially filtered through the above steps, the user can add extractant and gelling agent to the housing 1 through the feeding port to condense and remove solid impurities and sulfur dioxide in the wastewater, thereby ensuring that the equipment can purify exhaust gas and wastewater.
[0031] In a preferred embodiment: a controller is fixedly mounted on the outer wall of the housing 1, and the controller is electrically connected to the liquid level sensor 10, the pressurizing fan 6, and the high-temperature heating rod 11 respectively.
[0032] In the above structure, the controller allows users to control the operating time of each electronic component in the device, making it easier for users to operate and thus improving the automation of the device and reducing the difficulty of operation.
[0033] Working principle: After assembling the equipment, the user can directly add wastewater to the shell 1 through the wastewater pipe 4, and then introduce waste gas into the shell 1 through the waste gas pipe 3. At this time, the waste gas will enter below the surface of the wastewater, undergo preliminary filtration, and be separated from particulate matter. Subsequently, the gas-solid separated waste gas is introduced into the reaction vessel 5 by the operation of the pressurized fan 6. With the heating effect of the high-temperature heating rod 11, the sodium hydroxide solution reacts with the sulfur dioxide in the waste gas, thereby achieving the effect of purifying the waste gas. Then, the user can open the feeding port and add gelling agent and extractant to the inside of the shell 1 respectively. As the temperature rises, the sealing plug 20 is pushed, causing the moving ring 18 to compress the return spring 17, connecting the interior of the exhaust pipe 8 with the interior of the reaction vessel 5. This allows the exhaust pipe 8 to discharge excess hot air, which is then cooled by the low-temperature wastewater. The cold air is discharged from the outlet of the exhaust pipe 8, while the wastewater is heated for extraction, thus achieving the effect of treating waste gas and wastewater. At the same time, it can also recover and utilize heat energy, improving the energy utilization rate of the equipment. Furthermore, the equipment effectively maintains pressure balance during operation, improving the safety of the equipment during operation.
