Description

Technical Field

[0001] The utility model relates to the technical field of fume treatment of a setting machine, in particular to an energy-saving fume treatment device for a setting machine. Background Art

[0002] After dyeing and rinsing, textiles contain water, oil, solvent, paraffin, etc., which evaporate and cool during the heat setting process. The waste gas from the setting machine contains particulate matter, oil smoke and VOCs. The temperature of waste gas and waste dust is high and the pollution is serious. 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 discharged gas is clean or has very little pollution.

[0003] However, since there are a large amount of oil and smoke particles in the exhaust gas, a large amount of oil will accumulate on the connecting pipe connected to the purifier. Currently, a spray is installed at the air inlet end of the connecting pipe to perform pre-process oil removal and dust reduction for the exhaust gas. However, since the gas passes through the connecting pipe at a fast speed, the gas enters the connecting pipe and the purifier without being completely degreased and dusted. Over time, thick oil will accumulate on the inner wall of the connecting pipe, affecting the passability of the exhaust smoke, resulting in insufficient exhaust smoke intake pressure of the purifier. The air inlet pressure of the purifier can only be increased by installing a negative pressure fan. The fan consumes a lot of power and energy, and the oil in the connecting pipe and the purifier needs to be cleaned frequently. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model provides an energy-saving fume treatment device for a setting machine, such as Figure 1-3 As shown, it includes a connecting pipe 1 connected to the smoke exhaust port of the setting machine and a purifier 3 arranged at the end of the connecting pipe 1. The purifier 3 is a high-voltage electrostatic precipitator currently commonly used on the market. A first-level spray head 5 is arranged at the head end of the connecting pipe 1. A spray valve 4 for controlling the opening size is arranged on the first-level spray head 5. The first-level spray head 5 is connected to the water source through the spray valve 4. The connecting pipe 1 is arranged horizontally, and a plurality of spiral atomizing nozzles 8 are arranged at intervals along the length direction of the horizontal connecting pipe 1. The plurality of spiral atomizing nozzles 8 are connected to the water source through the spray pipe 6. The spiral atomizing nozzle 8 is an existing commercially available product. The water mist sprayed by the spiral atomizing nozzle is spiral-shaped and can cover various areas in the connecting pipe 1 to prevent the occurrence of spray dead angles. A plurality of sewage pipes 7 for discharging precipitated oil are arranged at intervals along the length direction at the bottom of the connecting pipe 1.

[0022] like Figure 2 As shown, the flue gas coming out of the setting machine enters the connecting pipe 1 after the first-level cooling by the first-level spray head 5. The spiral spray sprayed by the several spiral atomizing nozzles 8 in the connecting pipe 1 covers the inside of the connecting pipe 1 in all directions. The oil fume particles are demulsified by the water atomizing spray of the spiral atomizing nozzle 8 and discharged from the sewage pipe 7. The water enters the recycled water collection box 9 and is then recycled after the oil is scraped. This can effectively prevent the accumulation of oil on the inner wall of the connecting pipe 1, improve the passability of the waste smoke, eliminate the negative pressure fan in front of the purifier 3, save electricity, and because a large amount of oil and smoke are taken away to the sewage pipe 7 by the water mist, there is no need to frequently clean the oil in the connecting pipe 1 and the purifier 3.

[0023] A secondary dust removal device is provided between the connecting pipe 1 and the purifier 3 .

[0024] like Figure 3As shown, the secondary dust removal device includes a dust removal box 2, a plurality of dust removal plates 10, and a plurality of secondary spray heads 15. The cross section of the dust removal plate 10 is S-shaped, and the S-shaped bending shape can be bridge-shaped or wavy. The plurality of dust removal plates 10 are longitudinally arranged in the dust removal box 2, and two adjacent dust removal plates 10 form a flue gas channel 11 for flue gas to pass through. The front and rear ends of the flue gas channel 11 are respectively connected to the connecting pipe 1 and the purifier 3. The plurality of secondary spray heads 15 are arranged on the top of the dust removal box 2, and correspond to the plurality of dust removal plates 10 and the flue gas channel 11.

[0025] A dust removal box 2 is added between the connecting pipe 1 and the purifier 3, and an S-shaped bent dust removal plate structure is used to replace the fin cooling device currently on the market, thereby reducing the large resistance and thus eliminating the need for a 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 10 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 3 is less, preventing the purifier 3 from being blocked, and at the same time reducing the load of high-voltage static electricity, thereby achieving a power saving effect.

[0026] like Figure 2 As shown, the device also includes a recycling water collection box 9, and the tail interface of the dust removal plate 10 and the sewage pipe 7 are connected to the recycling water collection box 9. The water flowing back to the recycling water collection box 9 can be recycled after the surface oil is scraped off.

[0027] In order to lower the temperature of the flue gas entering the purifier 3, the dust removal plate 10 is hollow inside, and interfaces are set at both ends. The front interface of the dust removal plate 10 is connected to the power pump 14 through the inlet pipe 13. The power pump 14 is a water pump, and the water source is connected through the power pump 14. The rear end interface extends to the outside of the dust removal box 2 and is connected to the recycled water collection box 9. The flue gas temperature is reduced by heat exchange inside and outside the dust removal plate 10.

[0028] The dust removal plate 10 is made of stainless steel, which effectively improves its heat exchange effect.

[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.
