Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning circulation devices, and in particular relates to a high-efficiency dehumidification and drying air-conditioning circulation device. Background Art

[0002] Sludge drying is a method for treating water-containing sludge. Its main purpose is to remove moisture from the sludge to a certain dryness for subsequent processing, utilization, or disposal. Heat pump drying is a commonly used method for sludge drying. The heat pump's circulation extracts moisture from the sludge. The heat generated by the heat pump is transferred through a specific device and evaporator to achieve the purpose of drying. This method is relatively economical in equipment costs, suitable for small-scale treatment scenarios, and highly environmentally friendly. However, current devices of this type do not purify the airflow after contact with the sludge, requiring additional purification equipment. In addition, the evaporator has a high heat load, which increases the energy consumption of the entire system. Utility Model Content

The hot air that has passed the mesh conveyor belt flows upward into the rising air duct and merges inside the top converging air duct, and then flows into the filter bin through the first return air duct, and the dust contained in the air is filtered through the stainless steel filter mesh and the fiber filter plate, and then the air flow passes through the activated carbon filled filter element plate, the ceramic fiber filled filter element plate, and the molecular sieve filled filter element plate in turn to adsorb the harmful components therein, which plays the first step of purification. Then the air flow enters the spray device, and the water pump stores the spray liquid in the spray bin The liquid is pumped out to the heat exchange pipe section, and the spray liquid in the heat exchange pipe section contacts the hot air inside the heat pump installation chamber and is quickly heated. It then enters the spray water distribution pipe and is evenly sprayed out through the atomizing nozzle to spray and purify the airflow in the spray device and neutralize it with the temperature of the airflow, thereby reducing the airflow temperature to a certain extent without cooling it too much. The hot air flow that has completed the spray purification stage flows back into the heat pump installation chamber through the second return air duct. Since the air has been cooled to a certain extent, the heat load of the evaporator in the heat pump assembly can be reduced, and its evaporation energy efficiency can be improved, thereby reducing the energy consumption of the heat pump assembly, while also purifying the harmful components in the airflow.

[0010] As a further improvement of the above technical solution: a push-pull handle is installed on the back side of the sealing plate.

[0011] The beneficial effect of this improvement is that the push-pull handle is used to facilitate pulling out and pushing back the sliding mounting bracket.

[0027] The heat pump assembly 4 generates hot air and blows the hot air upward through the induced draft fan 5. The hot air quickly dries the sludge transported on the mesh conveyor belt 2. The hot air that has passed through the mesh conveyor belt 2 flows upward into the rising air duct 6 and merges inside the top confluence air duct 7. Then it flows into the filter bin 9 through the first return air duct 8, and the dust contained in the air is filtered through the stainless steel filter 12 and the fiber filter plate 13. Then the air flow passes through the activated carbon filled filter plate 14, the ceramic fiber filled filter plate 15, and the molecular sieve filled filter plate 16 in turn to adsorb the harmful components therein, which plays the first step of purification. Then the air flow enters the spray device 19, and the water pump 23 stores the spray liquid The spray liquid in the bottom bin 22 is pumped out to the heat exchange pipe section 24. The spray liquid in the heat exchange pipe section 24 contacts the hot air inside the heat pump installation bin 3 and is quickly heated. It then enters the spray water distribution pipe 20 and is evenly sprayed out through the atomizing nozzle 21, spraying and purifying the airflow in the spray device 19 and neutralizing it with the temperature of the airflow, thereby reducing the airflow temperature to a certain extent without causing it to be overcooled. The hot air flow that completes the spray purification stage flows back into the heat pump installation bin 3 through the second return air duct 25. Since the air has been cooled to a certain extent, the heat load of the evaporator in the heat pump assembly 4 can be reduced, and its evaporation energy efficiency can be improved, thereby reducing the energy consumption of the heat pump assembly 4.

[0028] The filter element group includes a stainless steel filter screen 12 , a fiber filter screen plate 13 , an activated carbon filled filter element plate 14 , a ceramic fiber filled filter element plate 15 , and a molecular sieve filled filter element plate 16 .

[0029] After the airflow enters the filter chamber 9, the dust contained in the air is filtered through the stainless steel filter 12 and the fiber filter plate 13. Then the airflow passes through the activated carbon filled filter plate 14, the ceramic fiber filled filter plate 15, and the molecular sieve filled filter plate 16 in turn to adsorb the harmful components therein, playing the first step of purification.

[0030] A push-pull handle 17 is installed on the back of the sealing plate 11 .

[0031] The push-pull handle 17 is used to facilitate pulling out and pushing back the sliding mounting bracket 10 .

[0032] A limit rotating plate 18 is rotatably mounted on the back of the filter bin 9 , and a supporting plate 27 is provided on the back of the sealing plate 11 .

[0033] After the sliding mounting frame 10 is pushed into the filter chamber 9 , the limiting rotating plate 18 is rotated to limit the sealing plate 11 to prevent the sliding mounting frame 10 from sliding out by itself, and the supporting plate 27 supports the limiting rotating plate 18 .

[0034] The heat exchange pipe section 24 passes through the heat pump installation chamber 3 and passes outward from it to be connected to the spray water distribution pipe 20.

[0035] The water pump 23 pumps the spray liquid in the spray liquid storage bottom bin 22 out to the heat exchange pipe section 24. The spray liquid in the heat exchange pipe section 24 contacts the hot air inside the heat pump installation bin 3 and is quickly heated.

[0036] The working principle and usage process of the utility model are as follows: when the device is in use, the heat pump component 4 generates hot air and blows the hot air upward through the induced draft fan 5. The hot air quickly dries the sludge transported on the mesh conveyor belt 2. The hot air that has passed the mesh conveyor belt 2 flows upward into the rising air duct 6 and merges inside the top converging air duct 7. Then, it passes through the first return air duct 8 and flows into the filter bin 9, and is filtered by the stainless steel filter mesh 12 and the fiber filter plate 13. The dust contained in the air is filtered. Then, the air flow passes through the activated carbon filled filter element plate 14, the ceramic fiber filled filter element plate 15, and the molecular sieve filled filter element plate 16 in turn to adsorb the harmful components therein, which plays the first step of purification. Then, the air flow enters the spray device 19, and the water pump 23 pumps the spray liquid in the spray liquid storage bottom bin 22 out to the heat exchange pipe section 24. The spray liquid in the heat exchange pipe section 24 contacts the hot air inside the heat pump installation bin 3, is quickly heated, and then enters the spray water distribution pipe The hot air flow that has completed the spray purification stage is returned to the heat pump installation chamber 3 through the second return air duct 25. Since the air has been cooled to a certain extent, the heat load of the evaporator in the heat pump assembly 4 can be reduced, and its evaporation energy efficiency can be improved, thereby reducing the energy consumption of the heat pump assembly 4. When it is necessary to replace each filter screen and filter element, the limit rotating plate 18 is rotated to separate it from the obstruction of the sealing plate 11, and the sliding mounting frame 10 can be pulled out by the push-pull handle 17, and then each filter screen and filter element can be replaced. After the replacement is completed, the sliding mounting frame 10 is pushed back to its original position, and the limit rotating plate 18 is rotated to limit it to the sealing plate 11 to prevent the sliding mounting frame 10 from sliding out by itself. The supporting plate 27 plays a supporting role for the limit rotating plate 18.
