Description

Technical Field

[0001] The utility model relates to the technical field of fume treatment of a setting machine, in particular to a circulating water cooling device of a waste fume purification system of a setting machine. Background Art

[0002] When the setting machine is running, it usually generates a large amount of waste gas and waste dust, which has high temperature and serious pollution. In order to reduce the pollution of waste gas and waste dust, electrostatic purification and other equipment are generally used to treat the waste gas, so that the exhausted gas is clean or has very little pollution.

[0003] Since the exhaust gas temperature is high and there are a lot of oil and smoke particles in the exhaust gas, and the low-temperature flue gas has a better purification effect, in order to make the flue gas temperature entering the electrostatic purifier lower and the oil and particle content in the flue gas lower, it is necessary to add a spray device on the connecting pipe between the purifier and the setting machine for spraying dust and oil reduction, and add a heat exchange device for cooling the flue gas. However, there are two shortcomings in the heat exchange device currently used. First, the heat exchange generally uses a straight tube as a heat exchange tube, and the heat exchange is carried out by convection inside and outside the tube. Since the water in the straight tube passes faster, it cannot form a good heat exchange effect with the flue gas, resulting in the flue gas passing through the heat exchange device without sufficient cooling, and the cooling effect is not good. Second, the cooling water after heat exchange is directly passed into the recovery pool for natural cooling and reuse. In the hot summer, the cooling effect is not good, resulting in poor flue gas heat exchange effect. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model embodiment provides a circulating water cooling device for the waste smoke purification system of a setting machine, such as Figure 1-3 As shown, it includes a connecting pipe 1, a dust removal and cooling device 3, and a purifier 2 which are sequentially arranged along the air outlet of the setting machine. The purifier 3 is a high-voltage electrostatic precipitator currently commonly used in the market.

[0020] The dust removal and cooling device 3 includes a box body 31 and a plurality of dust removal plates 32 bent in an S-shape. The bending of the dust removal plates 32 can be as follows: Figure 1 A plurality of dust removal plates 32 are arranged in the box body 31 at a longitudinal interval, and a flue gas channel 33 is formed between two adjacent dust removal plates 32. The front and rear ends of the plurality of flue gas channels 33 are respectively connected to the connecting pipe 1 and the purifier 2. The interior of the dust removal plate 32 is a hollow heat exchange channel 34. The heat exchange medium in the heat exchange channel 34 is in a convection state in the opposite direction of the flue gas.

[0021] like Figure 3 As shown, the top of the box body 31 is provided with several rows of spray groups 37 corresponding to the dust removal plates 32 one by one. The spray group 37 adopts a spiral atomizing nozzle, which is an existing commercially available product. The water mist sprayed by the spiral atomizing nozzle is spiral-shaped, and the flow rate of the flue gas can be slowed down when passing through the dust removal plate 32. The oil and particulate matter will adhere to the dust removal plate 32 under the action of the spray. The bottom sewage pipe of the box body 31 is connected to the sewage recovery tank 5. The dust removal plate 32 and the flue gas channel 33 are sprayed by the spray group 37, and the oil and particulate matter in the flue gas are settled and flushed into the sewage recovery tank 5 together with the oil attached to the dust removal plate 32.

[0022] The dust collector 3 adopts an S-shaped bent dust removal plate structure to replace the fin cooling device currently on the market, which reduces the large resistance and thus saves the negative pressure fan. The air is only supplied by the external exhaust fan of the setting machine, thereby achieving the effect of saving electricity and energy. At the same time, since there is no large resistance, the rotation speed of the setting fan is reduced, thereby reducing the energy consumption of the setting machine. At the same time, the dust removal plate 32 can greatly increase the smoke and oil interception and purification effect at this section, so that the oil and particulate matter content in the smoke entering the purifier 2 is less, preventing the purifier 2 from being blocked, and at the same time reducing the load of high-voltage static electricity, achieving a power saving effect.

[0023] like Figure 1 As shown, the cooling device 4 includes a cooling box 41, a plurality of heat exchange plates 42 with S-shaped bends, and the bends of the heat exchange plates 42 may be bridge-shaped or wave-shaped. The plurality of heat exchange plates 42 are arranged in the cooling box 41 at longitudinal intervals, and a heat dissipation channel 44 is provided between two adjacent heat exchange plates 42. The interior of the heat exchange plates 42 is a hollow circulating water channel 43, and the front and rear ends of the heat exchange channel 34 are connected to the front and rear ends of the circulating water channel 43 through a water inlet pipe 35 and a water outlet pipe 36. The inlet and outlet of each heat dissipation channel 44 are collected on a main inlet pipe 45 and a main outlet pipe 46, and heat absorbing mechanisms are connected to both ends of the main inlet pipe 45 and the main outlet pipe 46.

[0024] The S-shaped bent heat exchange plate 42 is used to replace the straight tube type cooling device currently on the market, which can increase the stroke of hot water and slow down its flow rate, increase the heat exchange area and heat exchange time, and achieve sufficient cooling.

[0025] The dust removal plate 32 and the heat exchange plate 42 are made of stainless steel. The dust removal plate 32 made of stainless steel is easy to wash away the oil stains attached to the surface, and the heat exchange efficiency is also high.

[0026] like Figure 1 As shown, the heat absorption mechanism includes a water pump 6, a fan 8, a three-way valve 7, a circulating water pipe 10, an air inlet pipe 11 and an air outlet pipe 12. The water pump 6 is arranged on the circulating water pipe 10. A cooling pool can be arranged and connected in series to the circulating water pipe 10. The cooling pool is used to store cooling water. A compression refrigerator 9 is connected in series to the circulating water pipe 10. The compression refrigerator 9 is an existing commercially available product and is used to cool down the cooling water. The fan 8 is arranged on the air inlet pipe 11. One end of the air inlet pipe 11 and the circulating water pipe 10 is connected to the main inlet pipe 45 of the heat dissipation channel 44 through the three-way valve 7. The other end of the air outlet pipe 12 and the circulating water pipe 10 is connected to the main outlet pipe 46 of the heat dissipation channel 44 through the three-way valve 7. The heat absorption mechanism can be set to two cooling modes through two three-way valves 7, namely, a water cooling mode and an air cooling mode.

[0027] When the water cooling mode is adopted, the two three-way valves 7 are switched to the circulating water channel 43, and water is supplied by the water pump 6. When the water temperature is high, the compression refrigerator 9 can also be used to assist in cooling. The water cooling mode is suitable for summer.

[0028] When the air cooling mode is adopted, the two three-way valves 7 are switched to the air inlet pipe 11 and the air outlet pipe 12, and air is drawn into the heat dissipation channel 44 through the fan 8, and then discharged into the atmosphere through the air outlet pipe 12. The air cooling mode is suitable for winter when the temperature is lower.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
