Description

Technical Field

[0001] The invention relates to the field of dry circulating gas purification and treatment, and in particular to a circulating dry gas purification and treatment system. Background Art

[0003] As a key equipment for post-printing and dyeing finishing, the dyeing and setting drying fan will blow out gas containing organic matter and fuel additives when working. The fuel additives have complex compositions and many harmful components. If they are discharged directly into the atmosphere, they will cause serious pollution to the ambient atmosphere and affect the health of workers and residents near the printing and dyeing factory.

[0004] In order to solve the above problems, the gas in the printing and dyeing process can be circulated by the heat pump inside the system instead of being discharged into the atmosphere. The dry gas with oil smoke blown out by the dyeing, finishing and shaping drying fan is first passed into the condenser for cooling, and then passed into the gas purification treatment system for purification and further cooling. The circulating gas is then passed into the evaporator and compressor for heating and compression to turn it into high-temperature dry gas. Finally, the high-temperature dry circulating gas is passed into the drying fan for dyeing, finishing and shaping the fabric, thereby completing a gas recycling process.

[0005] However, the current circulating dry gas purification treatment system has a single structure, and the simple treatment process makes the purification of the circulating dry gas not thorough enough and inefficient, affecting the effective gas circulation. In addition, the filter purification components of the current dyeing and finishing machine oil fume drying circulating gas treatment system need to be frequently taken out for cleaning, which increases the workload of workers.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following embodiments are combined with the accompanying drawings to specifically illustrate the circulating dry gas purification system of the present invention.

[0022] Figure 1It is a front view of a circulating dry gas purification system in an embodiment of the present invention. Figure 2 It is a right side view of the circulating dry gas purification treatment system in an embodiment of the present invention.

[0023] like Figure 1-2 As shown, the circulating dry gas purification system 100 in this embodiment includes a system housing 10 , a water pump 50 , a water spraying device 20 , a roller frame 30 and an ultrasonic cleaning water tank 40 .

[0024] A baffle 11 is arranged inside the system housing 10, which divides the system housing 10 into an upper housing 12 and a lower housing 13. A gas inlet 14 is arranged on one side of the upper part of the lower housing 13 for introducing the gas to be purified, and an outlet air duct 15 is arranged on the other side for discharging the purified gas.

[0025] The water pump 50 is arranged inside the upper shell 12. One end of the water pump 50 is connected to a water supply pipe 51. The water supply pipe 51 passes through the upper shell 12 to supply water to the water pump 50. The other end of the water pump 50 is connected to a water outlet pipe 52. The water outlet pipe 52 passes through the baffle 11 to deliver water into the lower shell 13.

[0026] The water spraying device 20 is arranged at the top of the lower shell 13 and connected to the water outlet pipe 52 for spraying water mist to the lower shell 13. The water spraying device 20 includes a plurality of water spraying holes 21, which are arranged in a row on the water spraying device 20 so as to evenly purify the gas.

[0027] The roller frame 30 is arranged in the lower shell 13. The roller frame 30 is a cylinder. The curved surface of the cylinder is covered with a porous medium filter 31. The roller frame 30 is connected to the lower shell 13 through a transmission connecting rod 32. The transmission connecting rod 32 is detachably arranged at the center position of the circular plane of the roller frame 30, which is convenient for repairing and replacing the porous medium filter 31 on the roller frame 30.

[0028] The motor 33 is fixed on a fixed rod outside the lower shell 13 , connected to the transmission connecting rod 32 , and colinear with the center of the circular plane of the roller frame 30 , so as to provide power for the rotation of the roller frame 30 .

[0029] The roller frame 30 can perform circular motion around the center of a circle when driven by the motor 33 .

[0030] The ultrasonic cleaning water tank 40 is disposed at the bottom of the lower housing 13 and is used to contain the water sprayed by the water spraying device 20 .

[0031] The height of the side wall of the ultrasonic cleaning water tank 40 is the same as the center height of the circular plane of the roller frame 30 , so that the porous medium filter 31 can be immersed in water as the roller frame 30 rolls, thereby achieving cyclic cleaning of the porous medium filter 31 .

[0032] A sewage outlet 41 penetrating the lower shell 13 is provided at the bottom of the side wall of the ultrasonic cleaning water tank 40. The sewage outlet 41 is connected to a sewage treatment center (not shown in the figure) for discharging sewage in the ultrasonic cleaning water tank 40 and allowing it to flow directly into the sewage treatment center for treatment and purification to avoid pollution. The treated and purified water flows back into the water pump 50 through the water supply pipe 51, and enters the water sprinkling device 20 again under the drive of the water pump 50, thereby repeatedly and efficiently performing the purification process of the dry circulating gas.

[0033] The working principle of the present invention is:

[0034] The dry circulating gas to be purified is introduced into the gas inlet 14 , and the porous medium filter 31 on the side curved surface of the roller frame 30 can adsorb the oil fume particles in the gas to be purified.

[0035] The water pump 50 is started, so that the water spraying device 20 sprays the water mist which has been processed and purified outside the system above the inside of the system housing 10. At this time, the water mist can also absorb the oil smoke particles wrapped in the dry circulating gas and then fall into the water tank.

[0036] The purified gas is discharged through the outlet air duct 15.

[0037] Start the motor 33 and the ultrasonic cleaning water tank 40. The motor 33 drives the roller frame 30 with the porous medium filter 31 to rotate around the center of the circular plane. As the roller frame 30 rotates, the porous medium filter 31 that has adsorbed the oil fume particles enters the water of the ultrasonic cleaning water tank 40. The ultrasonic cleaning water tank 40 cleans the porous medium filter 31 immersed in the water. As the roller frame 30 continues to rotate, the cleaned porous medium filter 31 leaves the water surface and continues to adsorb the oil fume particles in the dry circulating gas.

[0038] The contaminated water in the water tank flows out along the sewage outlet 41 to the water treatment center (not shown in the figure) outside the system shell 10 for treatment and purification. The treated and purified water flows into the water supply pipe 51 and re-enters the water sprinkling device 20 driven by the water pump 50, thereby repeatedly and efficiently performing the purification process of the dry circulating gas.

[0039] Functions and Effects of the Embodiments

[0040] According to the circulating dry gas purification treatment system involved in the present invention, the present invention purifies the gas through the water mist sprayed by the water spraying device and the porous medium filter covered on the outside of the roller frame. The water mist sprayed by the water spraying device absorbs the oil fume particles in the gas and falls into the ultrasonic cleaning water tank. Part of the roller frame is immersed in the ultrasonic cleaning water tank. As the roller frame rotates, the porous medium filter covered on its curved surface can cyclically enter and leave the water in the ultrasonic cleaning water tank, thereby achieving a circulating cleaning effect and ensuring that the gas entering the shell through the gas inlet is fully purified.

[0041] The present invention uses an ultrasonic clear water tank to clean the porous medium filter, which has the advantages of short cleaning time, good cleaning effect, and reduced labor intensity, further ensuring the filtering and adsorption effect of the filter, saving the step of constantly replacing the porous medium filter, improving the purification efficiency of the gas purification treatment system, and reducing the workload of workers.

[0042] The connection mode between the roller frame and the transmission connecting rod of the present invention is a detachable connection, which is convenient for repairing and replacing the porous medium filter screen on the roller frame, and saves the later maintenance cost.

[0043] The present invention adsorbs the oil fume particles in the dry circulating gas through a porous medium filter, and the sprayed water mist can also adsorb and wrap the oil fume particles, while cooling the circulating gas. The two purification processes are carried out simultaneously, making the treatment of the oil fume dry circulating gas more efficient and more effective.

[0044] The present invention enables the porous medium filter to automatically enter the ultrasonic cleaning water tank for cleaning through the rotation of the roller frame, thereby reducing the workload of workers in the later equipment operation process.
