Description

Technical Field

[0001] This utility model relates to the field of dyeing machine technology, and more specifically, to a waste gas recycling device for dyeing machines. Background Technology

[0002] In the textile dyeing and processing field, dyeing machines are the core equipment for coloring materials. After dyeing, the fabric needs to undergo high-temperature color fixing treatment through hot rollers to achieve a stable dyeing effect. They are widely used in large-scale production scenarios of textile printing and dyeing. However, in the actual production process, the hot roller generates a large amount of high-temperature waste gas when curing dyes at high temperatures. The waste gas contains harmful substances such as volatile organic compounds and dye decomposition products, which will diffuse to the area around the hot roller. At the same time, the harmful substances in the waste gas will be inhaled by the operators along with the air flow in the production workshop, posing a threat to their health. Secondly, the high-temperature waste gas contains a large amount of heat energy, which cannot be effectively recovered and reused, resulting in a waste of resources.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waste gas recycling device for dyeing machines.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a waste gas recycling device for a dyeing machine, comprising a dyeing machine body, wherein the dyeing machine body is composed of a color-fixing chamber and a plurality of dyeing chambers; The dyeing chamber has a dye pool and a heat recovery tank at the bottom. The heat recovery tank has a U-shaped cross-section and is located around the dye pool. Two through holes are symmetrically opened on both sides of the bottom of the dyeing chamber. The through holes are connected to the heat recovery tank and are respectively connected to an air inlet pipe and an air outlet pipe. The top of the color-fixing chamber is connected to a fan. The air outlet of the fan is connected to the end of several air inlets away from the dye pool through an air supply pipe. Several through slots are arrayed on the peripheral wall of the dye pool. Heat-conducting blocks are installed in the through slots. The length of the heat-conducting blocks extends to the dye pool and the heat recovery tank on both sides, respectively. The heat-conducting blocks absorb the temperature in the high-temperature waste gas and transfer it to the dye pool through heat transfer.

[0006] The present invention is further configured such that: the length and thickness of the heat-conducting block are the same as the length and width of the through groove; the heat-conducting block is made of aluminum; and the heat-conducting block is welded and sealed to the dye pool.

[0007] The present invention is further configured such that: the length of the through groove is the same as the depth of the dye pool, and a gap is left between the heat-conducting block and the side wall of the heat recovery tank away from the dye pool.

[0008] The present invention is further configured such that: a number of hot rollers are rotatably connected in the color-fixing chamber, and one end of the number of air outlet pipes away from the dye pool is connected to the waste gas treatment equipment through an air supply pipe.

[0009] The present invention is further configured such that: a guide roller is rotatably connected to the bottom of the dye pool, and a liquid supply pipe is connected to the bottom of several dye pools; the liquid supply pipe is provided with several through holes arranged in an array on the peripheral wall of the dye pool.

[0010] In summary, this utility model has the following beneficial effects: the high-temperature waste gas generated in the color-fixing chamber is introduced into the heat recovery tank, and the heat in the waste gas is absorbed by several heat-conducting blocks and then conducted to the dye pool for heating the dye. The fluidity of the dye can be guaranteed without setting up an additional heating device, thus realizing the effective utilization of waste heat resources. The high-temperature waste gas generated in the color-fixing chamber is actively extracted by the fan and pipeline system, and after the waste heat is recovered in the heat recovery tank, it is transported to the waste gas treatment equipment for purification and discharge, preventing the spread of high-temperature and harmful waste gas in the workshop.

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] Example: Waste gas recovery device for dyeing machine, such as Figures 1-3As shown, the dyeing machine includes a dyeing machine body 1, which consists of a color-fixing chamber 101 and several dyeing chambers 102. Several hot rollers 11 are rotatably connected inside the color-fixing chamber 101 for high-temperature color-fixing treatment of the dyed fabric. A dye pool 2 and a heat recovery tank 3 are provided at the bottom of the dyeing chamber 102. The heat recovery tank 3 has a U-shaped cross-section and is located around the dye pool 2. Two through holes 4 are symmetrically opened on both sides of the bottom of the dyeing chamber 102. The through holes 4 are connected to the heat recovery tank 3. The two through holes 4 are respectively connected to an air inlet pipe 5 and an air outlet pipe 6. A fan 7 is connected to the top of the color-fixing chamber 101. The air outlet of the fan 7 is connected to the end of several air inlet pipes 5 on the same side away from the dye pool 2 through an air delivery pipe 8. The high-temperature waste gas generated in the color-fixing chamber 101 can be transported to several heat recovery tanks 3 by the fan 7.

[0015] like Figures 1-3 As shown, the peripheral wall of the dye pool 2 is arrayed with several through slots 9, and a heat-conducting block 10 is installed in each slot 9. The length of the heat-conducting block 10 extends into the dye pool 2 and the heat recovery tank 3 on both sides. The heat-conducting block 10 is made of aluminum, which has good thermal conductivity. Through the heat transfer of several heat-conducting blocks 10, heat from the high-temperature exhaust gas is absorbed and conducted into the dye pool 2 to heat the dye in the dye pool 2, maintaining the fluidity of the dye. This eliminates the need for additional heating devices in the dye pool 2, reducing the energy consumption of the dyeing machine body 1 during processing, and simultaneously realizing waste heat recovery. For efficient utilization of heat resources, both the dye pool 2 and the heat recovery tank 3 are welded from stainless steel plates. Stainless steel has poor thermal conductivity, thus reducing heat loss. The length and thickness of the heat-conducting block 10 are the same as the length and width of the through groove 9. The heat-conducting block 10 is welded and sealed to the dye pool 2 to prevent dye leakage in the dye pool 2. The length of the through groove 9 is the same as the depth of the dye pool 2, ensuring uniform temperature in the dye pool 2. A gap is left between the heat-conducting block 10 and the side wall of the heat recovery tank 3 away from the dye pool 2 to prevent the heat-conducting block 10 from blocking the flow of exhaust gas.

[0016] like Figures 1-3As shown, several exhaust pipes 6 are connected to the exhaust gas treatment equipment via exhaust pipe 12 at the ends away from the dye pool 2. The high-temperature exhaust gas generated in the color fixing chamber 101 is actively extracted by the fan 7 and the pipeline system, and after waste heat recovery in the heat recovery tank 3, it is transported to the exhaust gas treatment equipment for purification and discharge, preventing the spread of high-temperature and harmful exhaust gas in the workshop. At the same time, the high-temperature exhaust gas is cooled down by heat transfer in the heat recovery tank 3, so that the high-temperature exhaust gas is cooled down in advance before entering the exhaust gas treatment device, reducing the cost required for subsequent exhaust gas cooling and purification. A guide roller 13 is rotatably connected to the bottom of the dye pool 2 to guide the fabric downward to the bottom of the dye pool 2 for dyeing. Several dye pools 2 are connected to the bottom of the supply pipe 14. Several through holes 15 are arrayed on the peripheral wall of the supply pipe 14 inside the dye pool 2. One end of the supply pipe 14 is connected to a water pump to replenish the dye in the dye pools 2.

[0017] Working principle: The high-temperature waste gas generated in the color fixing chamber 101 is drawn by the fan 7 and transported into several heat recovery tanks 3 through the first air supply pipe 8 and several air inlet pipes 5. The heat in the high-temperature waste gas is absorbed by several heat-conducting blocks 10 through heat transfer and conducted to the dye pool 2. The temperature in the dye pool 2 is increased to maintain the fluidity of the dye. The waste gas in the several heat recovery tanks 3 enters the waste gas treatment equipment through several exhaust pipes from the second air supply pipe 12 for purification before being discharged.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
