Description

Technical Field

[0001] The present application relates to the technical field of stenting machines, and in particular to a waste gas heat energy recovery device for stenting machines. Background Art

[0002] In the textile industry, the printing and dyeing setting machine is the main processing equipment and also one of the energy-consuming equipment. It is a device that uses heated air to dry and shape the fabric.

[0003] The hot air temperature required by the setting machine when in use is about 200℃, and the exhaust temperature of the exhaust gas from the setting machine is also about 150℃, which contains rich heat energy. At the same time, the exhaust gas also contains a large amount of impurities such as chemical fibers, lint and particles. The existing exhaust gas treatment generally adopts spraying to remove impurities and cool the exhaust gas, but the heat energy in the exhaust gas is wasted, and in order to remove a large amount of impurities in the exhaust gas, more water resources will be consumed, resulting in energy waste. Summary of the invention

[0004] In order to reduce energy waste, the present application provides a device for recovering waste gas heat from a molding machine.

[0005] The present application provides a heat recovery device for waste gas from a setting machine, which adopts the following technical solution:

[0006] A heat recovery device for waste gas of a setting machine comprises a frame, on which a recovery mechanism is arranged, and the recovery mechanism comprises:

[0007] A recovery box, wherein the recovery box is arranged on a frame and is provided with an exhaust gas passage for exhaust gas to pass through and an air passage for normal air to pass through;

[0008] A heat transfer component, which is disposed on the recovery box and is used to transfer the heat of the exhaust gas to the air;

[0009] An air inlet pipe and an air outlet pipe, which are arranged on the recovery box and communicated with the exhaust gas passage and are used for inputting and outputting the exhaust gas;

[0010] An electrostatic adsorption component, which is disposed on the air inlet pipe and uses static electricity to adsorb impurities in the exhaust gas;

[0011] A spray assembly is arranged on the frame and is used to remove impurities remaining in the exhaust gas output from the exhaust pipe.

[0012] By adopting the above technical solution, the waste gas is passed through the electrostatic adsorption component to remove the easily adsorbed impurities in the waste gas, and then the waste gas enters the waste gas channel through the air inlet pipe and the air enters the air channel. The heat in the waste gas is transferred to the air through the heat transfer component, so as to heat the air. After the air is heated, it is output for use. After the waste gas is output through the air outlet pipe, it passes through the spray component again to continue to remove impurities. Therefore, the impurities in the output air outlet pipe have been removed, thereby reducing the water consumption of the spray component, and the heat in the waste gas is used to heat the air, thereby reducing the waste of heat and water resources.

[0013] Furthermore, the exhaust gas is first dust-removed before coming into contact with the heat transfer component, thereby reducing the risk of impurities remaining on the heat transfer component and reducing the heat transfer effect, thereby further reducing energy waste and achieving energy conservation and environmental protection.

[0017] By adopting the above technical solution, the spiral blade increases the contact area with the exhaust gas and air. At the same time, the spiral blade and the heat transfer rod cooperate to transfer heat, thereby improving the heat transfer efficiency and further reducing energy waste. The spiral structure can also make the impurities remaining on the heat transfer spiral blade fall under the subsequent exhaust gas push and its own gravity, thereby further reducing energy waste.

[0018] Optionally, the electrostatic adsorption component includes:

[0019] An adsorption tube, the adsorption tube is arranged on the air inlet pipe and communicated with the air inlet pipe;

[0020] An electrostatic adsorption plate, the electrostatic adsorption plate is arranged at the connection between the adsorption tube and the air inlet pipe by rotating through a rotating shaft, the electrostatic adsorption plate has static electricity and is used to adsorb impurities in the exhaust gas and separate the adsorption tube and the air inlet pipe, a plurality of electrostatic adsorption plates are arranged in a circular array around the axis of the rotating shaft, and the number is an even number and at least six, and some of the electrostatic adsorption plates are located on the air inlet pipe to block the exhaust gas from passing through the air inlet pipe; two adjacent electrostatic adsorption plates cooperate with the inner side wall of the air inlet pipe to form a passing space for the exhaust gas to pass through, and at the same time, two adjacent electrostatic adsorption plates cooperate with the inner side wall of the adsorption tube to form a cleaning space for cleaning impurities on the electrostatic adsorption plate;

[0021] A control component is arranged on the air inlet pipe and is used to control the electrostatic adsorption plate that forms the passing space to be energized and the electrostatic adsorption plate that forms the cleaning space to be deenergized. The adsorption tube is also provided with a positioning component for positioning the rotating shaft under a certain elastic force and a cleaning and collecting mechanism for cleaning impurities on the electrostatic adsorption plate.

[0022] By adopting the above technical solution, the exhaust gas enters the passing space, the control component controls the electrostatic adsorption plate to be energized, the exhaust gas contacts the electrostatic adsorption plate and pushes the electrostatic adsorption plate to move, and the impurities in the exhaust gas that are easily adsorbed are adsorbed on the electrostatic adsorption plate, and the positioning component positions the electrostatic adsorption plate, so that more impurities are adsorbed on the electrostatic adsorption plate. At the same time, electrostatic adsorption can adsorb impurities located in the passing space, so that impurities that are not in contact with the electrostatic adsorption plate can be adsorbed on the electrostatic adsorption plate under suction, thereby improving the adsorption effect of impurities;

[0023] As the amount of exhaust gas in the air inlet pipe increases, the thrust of the exhaust gas on the electrostatic adsorption plate is greater than the positioning force of the positioning component, and the electrostatic adsorption plate is pushed to rotate. The exhaust gas is transported as it moves through the space, so that the exhaust gas moves from the air inlet pipe on one side of the adsorption tube to the air inlet pipe on the other side of the adsorption tube, thereby realizing the intermittent transportation of waste and removing impurities in the exhaust gas at the same time; the electrostatic adsorption plate enters the cleaning space as pushed by the exhaust gas, and at the same time, the control component controls the electrostatic adsorption plate to cut off the power, and then the cleaning and collection mechanism starts to remove and collect impurities on the electrostatic adsorption plate, and the cleaned electrostatic adsorption plate continues to rotate into the air inlet pipe, and then continues to adsorb and remove dust, thereby further improving the removal effect of impurities in the exhaust gas, thereby achieving energy saving and environmental protection effects.

When the thrust of the exhaust gas on the electrostatic adsorption plate is greater than the elastic force of the positioning spring, the positioning plate is separated from the positioning groove, and the rotation of the electrostatic adsorption plate drives the positioning plate to rotate, and the positioning plate is pressed against the positioning plate.

[0085] The working principle of the embodiment of the present application is as follows:

[0086] The exhaust gas of the positioning type machine enters the air inlet pipe 22, and then the exhaust gas enters the passing space 44, and the impurities in the exhaust gas are adsorbed on two adjacent electrostatic adsorption plates. As the amount of exhaust gas increases, the thrust of the exhaust gas on the electrostatic adsorption plate increases. When the thrust is greater than the elastic force of the positioning spring piece 63, the positioning spring piece 63 is separated from the positioning groove 64, and the electrostatic adsorption plate and the exhaust gas in the passing space 44 rotate together, so that the positioning spring piece 63 is snap-fitted and installed on the next positioning groove 64 to position the electrostatic adsorption plate, thereby realizing the delivery of the exhaust gas interval from one side of the adsorption tube 41 to the other side. , and at the same time, impurities in the exhaust gas are adsorbed and removed, and then the exhaust gas enters the exhaust gas channel 24, and the air enters the air channel 25. The heat in the exhaust gas is transferred to the air through the heat transfer spiral 32 and the heat transfer rod 31, so as to achieve heating of the air, and then the exhaust gas enters the spray box 51, the spray pump 72 is started, and water is sprayed through the spray hole 54 to spray the filter plate 52 and the exhaust gas, so as to achieve impurity removal of the exhaust gas, and the impurities enter the filter frame 73 for filtration, and the water enters the water storage tank 71 for recovery, thereby reducing the waste of resources and achieving energy saving and environmental protection.

[0087] When the electrostatic adsorption plate is rotated into the adsorption tube 41, the electrostatic adsorption plate is powered off, and water is sprayed out through the spray hole 54 at the same time, so as to remove impurities on the opposite side walls of the electrostatic adsorption plate. When the electrostatic adsorption plate continues to rotate to the next position, the cleaning cylinder 82 starts to drive the scraper 83 to move downward to scrape off the water and residual impurities on the electrostatic adsorption plate, and then the cleaning cylinder 82 starts to drive the scraper 83 to move back to the receiving tank, so as to remove impurities on the electrostatic adsorption plate. The electrostatic adsorption plate that removes water and impurities continues to rotate to the next position and becomes energized, and then it can continue to remove impurities in the exhaust gas. The impurities in the adsorption tube 41 enter the collection frame 92 for collection, and the water continues to flow to the water storage tank 71 for recycling, thereby further reducing resource waste and achieving energy conservation and environmental protection.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
