Description

Technical Field

[0001] The invention relates to the technical field of waste heat recovery equipment, and in particular to an RTO waste gas waste heat recovery treatment device. Background Art

[0002] RTO is a regenerative thermal oxidizer, which is a commonly used method for industrial waste gas treatment. It uses ceramic regenerators to store the heat generated when organic waste gas is decomposed, and uses the heat energy stored in the ceramic regenerators to preheat and decompose the untreated organic waste gas, thereby achieving a high thermal efficiency. The oxidation temperature is generally between 800℃ and 850℃.

[0003] The temperature of the waste gas treated by RTO is still at a high temperature, and it contains a high amount of waste heat resources. This is because when the concentration of volatile organic compounds in the waste gas is high, the waste gas will generate excess heat after oxidation. In order to prevent the waste heat in the RTO waste gas from being wasted, a recovery and treatment device is currently usually used to recover the waste heat in the RTO waste gas. When the recovery and treatment device is in use, the RTO waste gas is usually injected into the heat exchange tubes provided inside the recovery and treatment device. After that, cold water absorbs the heat in the RTO waste gas through the heat exchange tubes to achieve heat transfer. After absorbing the heat in the RTO waste gas, the cold water becomes hot water, which can be used in subsequent work, thereby achieving the effect of recovering the waste heat of the RTO waste gas.

[0004] When the existing RTO exhaust gas waste heat recovery and treatment device is in use, the contact area between the RTO exhaust gas and the heat exchange tube is limited, resulting in a relatively low efficiency in recovering the RTO exhaust gas waste heat. Over time, some heat will be wasted. Some recovery and treatment devices use multiple sets of driving equipment to simultaneously stir the RTO exhaust gas and cold water inside the recovery and treatment device, thereby increasing the contact area between the RTO exhaust gas and cold water and the heat exchange tube. Although this further improves the recovery efficiency of the RTO exhaust gas waste heat, it also makes the internal structure of the recovery and treatment device more complicated and the cost is relatively high. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide an RTO waste heat recovery and processing device. Through the matching arrangement of the adjusting cylinder and the bevel gear, the pushing plate can be driven to perform lateral reciprocating motion during the rotation of the stirring fan blade, and various stirring can be performed without increasing the space occupied by the stirring component, thereby increasing the contact area between the RTO waste gas and the heat exchange tube, and further improving the recovery efficiency of the RTO waste heat. Through the matching arrangement of the mounting plate and the guide slide column, the adjusting plate can drive the flow of cold water inside the tank body, and increase the contact area between the cold water and the heat exchange tube.

When the cold water absorbs the heat in the RTO exhaust gas, the driving device starts to run through the regulation of the control device, and the driving device starts to drive. The output shaft of the equipment drives the adjusting cylinder 51 to rotate, and the adjusting cylinder 51 drives the output rod 7 to rotate through the limiting rod 53. The central axis of the adjusting cylinder 51 and the output rod 7 is the same, and the output rod 7 drives the stirring blade 8 to rotate, so as to stir the RTO waste gas. When the adjusting cylinder 51 rotates, the adjusting cylinder 1 drives the fixed rod 56 to rotate through the meshing connection between the bevel gears 58, and the fixed rod 56 drives the adjusting rod 57 to rotate. At this time, the rear end of the adjusting rod 57 performs a circular motion around the fixed rod 56.

[0032] The device also includes a control switch 2, which is located outside the tank body 1. The input end of the control switch 2 is electrically connected to an external power source, and can regulate the electrical components inside the device.

[0033] It also includes a motor 16, which is arranged at the left end of the protective cover 4. The right end of the output shaft of the motor 16 is fixedly connected to the left end of the regulating cylinder 51.

[0036] The working principle of the RTO waste gas waste heat recovery treatment device provided by the present invention is as follows:

[0037] Before use, the RTO waste heat recovery device is moved to the designated work site by external traction equipment, and the mounting seat 14 is docked with the corresponding work station to achieve support and fixation of the tank body 1 and the internal equipment. Then, the air intake pipe 10, the exhaust pipe 11, the water inlet pipe 12 and the drain pipe 13 are docked with the external pipes respectively. When working, the air intake valve and the water inlet valve are opened, and the RTO waste gas is injected into the heat exchange tube 3 through the air intake pipe 10, and then the cold water is injected into the tank body 1 through the water inlet pipe 12. The cold water absorbs the RTO waste gas. Heat is transferred to realize heat transfer. Cold water absorbs the heat in the RTO exhaust gas and becomes hot water, thereby achieving the effect of recovering the waste heat of the RTO exhaust gas. When the cold water absorbs the heat in the RTO exhaust gas, the motor 16 starts to run through the control switch 2. The output shaft of the motor 16 drives the adjusting cylinder 51 to rotate.

The mounting plate 54 can drive the output rod 7 to perform a horizontal reciprocating motion through the limiting rod 53, so that the push plate 9 can be moved left and right when the stirring blade 8 is stirring. Move, thereby increasing the contact area between the RTO exhaust gas and the heat exchange tube 3, and further improving the recovery efficiency of the waste heat of the RTO exhaust gas. During the movement of the mounting plate 54, the mounting plate 54 drives the guide slide column 62 to move through the connecting plate 61, and the guide slide column 62 drives the adjusting plate 63 to perform a lateral reciprocating motion, thereby driving the cold water inside the tank body 1 to flow, increasing the contact area between the cold water and the heat exchange tube 3, thereby improving the heat absorption efficiency of the cold water.
