Description

Technical Field

[0001] This utility model relates to the field of waste gas detection technology, and in particular to a waste gas heavy metal collection device under high temperature environment. Background Technology

[0002] Waste gas heavy metal collection devices are equipment used to collect and analyze the heavy metal components in industrial waste gas.

[0003] Chinese Patent Publication No. CN207703562U, published on August 7, 2018, discloses a high-temperature flue gas collection device, including a sampling tube. One end of the sampling tube is provided with a sampling head, and the other end of the sampling tube is connected to a cooling device. The cooling device includes a water tank, and a cooling tube connected to the sampling tube is provided inside the water tank. The end of the cooling tube away from the sampling tube extends out of the water tank and is provided with a connector. The sampling tube and the cooling tube are connected by a thread. The end of the cooling tube near the sampling tube is provided with a connecting tube. The outer side of the connecting tube is provided with an external thread, and the inner wall of the end of the sampling tube near the connecting tube is provided with an internal thread.

[0004] Existing high-temperature exhaust gas heavy metal collection devices, such as those mentioned above, are mostly composed of two parts: a cooling component and a detection component. A negative pressure pump extracts part of the flue gas, and after cooling, the flue gas is transferred to a metal analyzer for detection. In practice, the cooling box is mostly an integrated structure, which makes it inconvenient to clean or replace the spiral tube later.

[0005] Therefore, how to design a heavy metal collection device for exhaust gas under high temperature environment to solve the above problems has become a technical problem that urgently needs to be solved by people in this field. Utility Model Content

[0006] The purpose of this utility model is to provide a heavy metal collection device for exhaust gas under high temperature environment in order to solve the above problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A waste gas heavy metal collection device for high-temperature environments includes a cooling chamber, a three-way collection pipe, and a metal analyzer. An inlet and an outlet are fixedly connected to both sides of the vertical end of the cooling chamber, and a collection port and a negative pressure pump are fixedly connected to both sides of the horizontal end of the cooling chamber. A spiral tube is fixedly connected between the collection port and the input end of the negative pressure pump. The three-way collection pipe includes port one, port two, and port three. The metal analyzer is integrated into port two. The output end of the negative pressure pump is connected to port three. A front cover and a fixing component for fixing the front cover are integrated into the front face of the cooling chamber.

[0009] Preferably, both port one and port three have integrated valves, and the front end of the three-way collection pipe has an integrated sampling section.

[0010] Preferably, the sampling section includes a sampling port fixedly connected to the front side of the three-way collection tube, and a cap screwed onto the outer wall of the sampling port.

[0011] Preferably, the outer wall of the cooling chamber is fixedly connected to a connecting frame by screws, and the outer wall of the connecting frame is fixedly connected to the outer wall of the three-way collection pipe.

[0012] Preferably, a sealing gasket is fixedly connected to the rear end face of the front cover.

[0013] Preferably, the fixing component includes a side piece fixedly connected to the outer wall of the front cover, and the side piece is fixedly connected to the outer wall of the cooling chamber via a locking rod.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this application, cooling liquid is introduced from the inlet until the entire cooling chamber is filled. The negative pressure pump operates, and a fixed amount of flue gas is introduced from the collection port. After passing through the spiral tube and the three-way transfer port, the flue gas is transferred to the inside of the three-way collection pipe. The spiral tube ensures the contact area between the flue gas and the cooling liquid, thereby effectively cooling the flue gas and preventing high-temperature flue gas from affecting the normal operation of the metal analyzer. The metal analyzer detects the flue gas inside the three-way collection pipe. Subsequently, the front cover can be separated by the locking rod. The flange assembly between the collection port and the negative pressure pump input end and the spiral tube can realize the independent disassembly and assembly of the spiral tube, ensuring the convenience of cleaning or replacing the spiral tube, thereby improving the ease of use of the high-temperature exhaust gas heavy metal collection device.

[0016] 2. In this application, when the heavy metal content of the flue gas meets the standard, port one is opened to allow the flue gas to be discharged directly. When the heavy metal content of the flue gas does not meet the standard, the valves on port one and port three are closed, and the staff can open the collection port to collect the flue gas. The gas is then transferred to a precision instrument for more accurate detection and component analysis, thus better meeting the needs of waste heavy metal treatment. Attached Figure Description

Detailed Implementation

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 This utility model provides a technical solution:

[0024] A waste gas heavy metal collection device under high temperature environment includes a cooling chamber 1, a three-way collection pipe 4 and a metal analyzer 5. The cooling chamber 1 has an inlet 2 and an outlet 3 fixedly connected to both sides of its vertical end, and a collection port 11 and a negative pressure pump 8 fixedly connected to both sides of its horizontal end. A spiral tube 12 is fixedly connected between the collection port 11 and the input end of the negative pressure pump 8. The three-way collection pipe 4 includes a first port 401, a second port 402 and a third port 403. The metal analyzer 5 is integrated in the second port 402. The output end of the negative pressure pump 8 is connected to the third port 403. The front end of the cooling chamber 1 has a front cover 9 and a fixing component for fixing the front cover 9.

[0025] Cooling liquid is introduced from inlet 2 until it fills the entire cooling chamber 1. The negative pressure pump 8 operates, and a fixed amount of flue gas is introduced from collection port 11. After passing through spiral tube 12 and port 3 403, it is transferred to the inside of the three-way collection pipe 4. Spiral tube 12 ensures the contact area between flue gas and coolant, thereby effectively cooling the flue gas and preventing high-temperature flue gas from affecting the normal operation of metal analyzer 5. The flue gas inside the three-way collection pipe 4 is detected by metal analyzer 5. Subsequently, the front cover 9 can be separated by separating locking rod 14. By separating the flange assembly between collection port 11 and the input end of negative pressure pump 8 and spiral tube 12, the spiral tube 12 can be independently disassembled and installed, ensuring the convenience of cleaning or replacing spiral tube 12, thereby improving the ease of use of the waste gas heavy metal collection device suitable for high temperature.

[0026] It should be noted that the metal analyzer 5 is already fully disclosed in the existing technology, so the specific working mechanism will not be described in detail here.

[0027] Specifically, such as Figure 2 and Figure 4As shown, both port 1 (401) and port 3 (403) have integrated valves, and the front end of the three-way collection pipe 4 has an integrated sampling section. The sampling section includes a sampling port 6 fixedly connected to the front side of the three-way collection pipe 4, and a cover 7 screwed onto the outer wall of the sampling port 6. When the heavy metal content of the flue gas meets the standard, port 1 (401) is opened to allow the flue gas to be discharged directly. When the heavy metal content of the flue gas does not meet the standard, the valves on port 1 (401) and port 3 (403) are closed, and the staff can open the sampling port 6 to collect the flue gas. The collected flue gas is then transferred to a precision instrument for more accurate detection and component analysis, thus better meeting the needs of waste heavy metal treatment. The outer wall of the cooling chamber 1 is fixedly connected to a connecting frame by screws. The outer wall of the connecting frame is fixedly connected to the outer wall of the three-way collection pipe 4 to ensure convenient disassembly and assembly of the three-way collection pipe 4.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, a sealing gasket 13 is fixedly connected to the rear end face of the front cover 9 to ensure the airtightness between the front cover 9 and the cooling chamber 1. The fixing component includes a side piece 10 fixedly connected to the outer wall of the front cover 9. The side piece 10 is fixedly connected to the outer wall of the cooling chamber 1 through a locking rod 14 to ensure the ease of disassembly and assembly of the front cover 9.

[0029] Working principle: Coolant is introduced through inlet 2 until the entire cooling chamber 1 is filled. Negative pressure pump 8 operates, and a measured amount of flue gas is introduced through collection port 11. After passing through spiral tube 12 and port 303, it is transferred to the inside of three-way collection pipe 4. Spiral tube 12 ensures the contact area between the flue gas and coolant, effectively cooling the flue gas and preventing high-temperature flue gas from affecting the normal operation of metal analyzer 5. The metal analyzer 5 detects the flue gas inside three-way collection pipe 4. Subsequently, the front cover 9 can be separated by separating locking rod 14. The separation process is completed at collection port 11 and the input end of negative pressure pump 8, connecting to spiral tube 11. The flange assembly between ports 2 and 3 allows for the independent disassembly and assembly of the spiral tube 12, ensuring convenient cleaning or replacement of the spiral tube 12. This improves the ease of use of the waste gas heavy metal collection device suitable for high-temperature applications. When the heavy metal content of the flue gas meets the standard, port 1 401 is opened to allow the flue gas to be discharged directly. When the heavy metal content of the flue gas does not meet the standard, the valves on port 1 401 and port 3 403 are closed, and the staff can open the sampling port 6 to collect the flue gas. The collected gas is then transferred to a precision instrument for more accurate detection and component analysis, thus better meeting the needs of waste heavy metal treatment.

[0030] Finally, any aspects of this utility model not fully described herein utilize existing mature products and technologies.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
