Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a condensation and dehydration device for an ultraviolet flue gas analyzer. Background Technology

[0002] During the use of ultraviolet (UV) flue gas analyzers, water vapor in the sample gas can affect the analytical results. Therefore, it is necessary to treat the sample gas by condensation and dehydration. Traditional methods typically use cooling coils or cold traps for dehydration, but these methods have certain drawbacks. For example, they have low cooling efficiency, which can easily cause condensate droplets to flow back into the analyzer, leading to instrument malfunction. Moreover, these traditional methods require more space, making it difficult to design compact equipment, and they also consume more energy, which is not conducive to energy conservation and reducing operating costs.

[0003] Chinese patent CN212631802U discloses a multi-tube flue gas condensation and dehydration device. This patent includes a chamber with a first partition fixedly connected to its inner circumferential wall. A water pump is fixedly installed on the left side of the chamber, and a water pump pipe is connected to the bottom of the pump. A conveying pipe is fixedly installed on the inner top wall of the chamber, and a water outlet pipe, with one end penetrating through and extending into the interior of the chamber and connected to the left side of the conveying pipe, is connected to the top of the water pump. In this multi-tube flue gas condensation and dehydration device, flue gas is introduced through an inlet pipe and then enters the first condensation tube. The water pump is then activated to draw in external cooling water, which is then conveyed through the outlet pipe to the inside of the conveying pipe. The water is then sprayed out through eight spray nozzles, and the cooling water from these nozzles contacts the first condensation tube, thus causing preliminary condensation of the flue gas inside.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] The existing device operates through eight spray nozzles. The cooling water sprayed from the eight nozzles comes into contact with the first condenser tube, thereby causing the flue gas inside the first condenser tube to undergo preliminary condensation. Then the flue gas enters the second condenser tube, where it undergoes secondary condensation and dehydration through the refrigeration end. Finally, the condensate is discharged through the second drain pipe. However, direct water spraying cannot ensure that the water comes into complete contact with the condenser tube, resulting in poor condensation effect. The sprayed water and condensate are discharged through the second drain pipe and cannot be reused, causing a waste of water resources. Utility Model Content

[0006] To address the aforementioned technical problems, this invention proposes a condensation and dehydration device for an ultraviolet flue gas analyzer. The device uses a first cooler to cool the coolant in a first cooling tank, causing water to condense from the flue gas in the cooling cylinder. At this time, the inlet pipe with a valve and the outlet pipe with a valve are closed. The initially condensed water flows into a storage tank. A first water pump then pumps the water from the storage tank through a first drain pipe into a collection box for collection. This prevents harmful substances contained in the flue gas from being directly discharged and causing environmental pollution.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a condensation and dehydration device for an ultraviolet flue gas analyzer, comprising a base plate, a plurality of first support feet mounted on the base plate, a first cooling box connected to the plurality of first support feet, a first cooler mounted on the first cooling box, a flue gas inlet pipe with a valve connected to the first cooling box, a cooling cylinder connected to the other end of the flue gas inlet pipe with a valve, a liquid storage tank connected to the cooling cylinder, both the liquid storage tank and the cooling cylinder being disposed inside the first cooling box, a first drain pipe connected to the liquid storage tank, a collection box mounted on the base plate, a first water pump mounted on the collection box, and the first water pump being connected to the first drain pipe.

[0008] In some embodiments, the other end of the cooling cylinder is connected to a flue pipe with a valve, the other end of the flue pipe with a valve is connected to a condenser box, a condenser rack is fixedly installed inside the condenser box, the condenser rack is hollow and contains a coolant, a liquid outlet pipe is connected below the condenser rack, the other end of the liquid outlet pipe is connected to a second cooling box, a liquid inlet pipe is connected above the condenser rack, a second water pump is installed on the second cooling box, and the second water pump is connected to the liquid inlet pipe.

[0009] In some embodiments, a second cooler is installed on the second cooling box.

[0010] In some embodiments, a negative pressure fan is installed on the condenser box, and a second drain pipe is connected to the bottom of the condenser box, with the other end of the second drain pipe connected to a collection box.

[0011] In some embodiments, a plurality of second support feet are fixedly installed at the bottom of the condenser box.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model discharges flue gas into a cooling cylinder through a valved inlet pipe. The cooling cylinder is located inside a first cooling box. The coolant in the first cooling box is cooled by the operation of a first refrigeration unit, causing the flue gas in the cooling cylinder to condense into water. At this time, the valved inlet pipe and the valved outlet pipe are closed. The initially condensed water flows into a storage tank. The water in the storage tank is pumped into a collection box through the first outlet pipe by the operation of a first water pump, thus avoiding the direct discharge of harmful substances contained in the water in the flue gas, which would cause environmental pollution.

[0014] Secondly, this utility model has a condenser rack installed inside the condenser box. The condenser rack is hollow inside. The coolant in the second cooling box is drawn into the condenser rack by the second water pump, and then discharged into the second cooling box through the outlet pipe to form a cycle. This allows the condenser rack to be kept at a low temperature. When the flue gas passes through the condenser rack, it can be condensed and drained again. This device uses recyclable coolant for condensation, avoiding the waste of water resources. Attached Figure Description

[0022] This utility model provides an improved condensation and dehydration device for an ultraviolet flue gas analyzer. The technical solution of this utility model is as follows:

[0023] like Figures 1-4 As shown, a condensation and dehydration device for an ultraviolet flue gas analyzer includes a base plate 1, on which multiple first support legs 2 are mounted. A first cooling box 3 is connected to the multiple first support legs 2. A first cooler 10 is mounted on the first cooling box 3. A flue gas inlet pipe 4 with a valve is connected to the first cooling box 3. The other end of the flue gas inlet pipe 4 with a valve is connected to a cooling cylinder 5. A liquid storage tank 6 is connected to the cooling cylinder 5. Both the liquid storage tank 6 and the cooling cylinder 5 are located inside the first cooling box 3. A first drain pipe 7 is connected to the liquid storage tank 6. A collection box 9 is mounted on the base plate 1. A first water pump 8 is mounted on the collection box 9. The first water pump 8 is connected to the first drain pipe 7. Flue gas enters the cooling cylinder 5 through the flue gas inlet pipe 4 with a valve. Since the cooling cylinder 5 is located inside the first cooling box 3, the water contained in the flue gas can be condensed and flows into the liquid storage tank 6. Then, the water is pumped into the collection box 9 by the first water pump 8.

[0024] Furthermore, the other end of the cooling cylinder 5 is connected to a flue pipe 11 with a valve, and the other end of the flue pipe 11 is connected to a condenser box 12. A condenser rack 13 is fixedly installed inside the condenser box 12. The condenser rack 13 is hollow inside and contains coolant. A liquid outlet pipe 14 is connected below the condenser rack 13, and the other end of the liquid outlet pipe 14 is connected to a second cooling box 15. An inlet pipe 16 is connected above the condenser rack 13. A second water pump 17 is installed on the second cooling box 15. The second water pump 17 is connected to the inlet pipe 16. The coolant circulates inside the condenser rack 13, so that the flue gas is condensed and dehydrated when it passes through the condenser rack 13.

[0025] Furthermore, a second cooler 18 is installed on the second cooling box 15.

[0026] Furthermore, a negative pressure fan 19 is installed on the condenser box 12, and a second drain pipe 20 is connected to the bottom of the condenser box 12. The other end of the second drain pipe 20 is connected to the collection box 9. The negative pressure fan 19 discharges the water-removed flue gas in the condenser box 12, and the second drain pipe 20 discharges the condensed water.

[0027] Furthermore, multiple second support feet 21 are fixedly installed at the bottom of the condenser box 12 to provide support.

[0028] The specific working method is as follows: This device discharges flue gas into the cooling cylinder 5 through the valved inlet pipe 4. The cooling cylinder 5 is located inside the first cooling box 3. The first cooler 10 cools the coolant in the first cooling box 3, causing the flue gas in the cooling cylinder 5 to condense into water. At this time, the valved inlet pipe 4 and the valved outlet pipe 11 are closed. The initially condensed water flows into the storage tank 6. The first water pump 8 pumps the water in the storage tank 6 into the collection tank 9 through the first drain pipe 7 to collect it, thus preventing the water in the flue gas from containing harmful substances and causing environmental pollution. Then, the valved outlet pipe 11 is opened to remove the initially dehydrated water. The flue gas is discharged into the condenser box 12, and a condenser rack 13 is installed inside the condenser box 12. The condenser rack 13 is hollow inside. The coolant in the second cooling box 15 is drawn into the condenser rack 13 by the second water pump 17, and then discharged into the second cooling box 15 from the outlet pipe 14 to form a cycle. This keeps the condenser rack 13 at a low temperature. When the flue gas passes through the condenser rack 13, it can be condensed and drained again. This device uses recyclable coolant for condensation, avoiding the waste of water resources. The water is discharged into the collection box 9 from the second drain pipe 20 at the bottom. The dried flue gas is discharged through the negative pressure fan 19.
