Description

Technical Field

[0001] The utility model relates to the technical field of dye production equipment, in particular to a waste gas recovery and purification mechanism for acid dye production. Background Art

[0002] At present, many dye production enterprises have insufficient understanding and investment in waste gas treatment, and often adopt simple emission methods, such as directly discharging waste gas into the atmosphere through the exhaust duct. This treatment method not only fails to effectively remove harmful substances in the waste gas, but also aggravates the degree of environmental pollution. Therefore, the development of an efficient and reliable acid dye production waste gas recovery and purification mechanism is of great significance to improving the working environment, protecting the ecological environment and achieving sustainable development of the dye industry.

[0003] However, since acid dyes are more sensitive to temperature, and in order to better meet emission standards, their reaction temperature needs to be processed in real time, and the temperature needs to be kept constant during purification. Therefore, an acid dye production waste gas recovery and purification device that can detect the temperature before discharging is needed to purify the waste gas. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model provides a waste gas recovery and purification mechanism for acid dye production, such as Figure 1-5 As shown, it includes a supporting base 101, a processing cylinder 102 is fixedly provided on the top of the supporting base 101, a control valve 104 is fixedly provided on the top of the processing cylinder 102, a processing chamber 117 is provided in the processing cylinder 102, an acid dye production waste gas purification device is provided in the processing chamber 117, a plurality of temperature control grooves 113 are connected on one side of the outer end surface of the processing cylinder 102, a glass plate for sealing is provided at the front end of the temperature control groove 113, an annular tube 118 is arranged in an annular manner in the processing cylinder 102, and a temperature control pipe 107 extending outward is connected at the front and rear ends of the annular pipe 118, the temperature control pipe 107 at the bottom is an input pipe, and the temperature control pipe 107 at the top is an output pipe.

[0026] It should be noted that a purified exhaust gas output valve is provided inside the control valve 104 .

[0027] Furthermore, a flow meter 103 is fixedly provided at a middle position on one side of the outer end surface of the treatment tube 102 , and an arc-shaped elbow 120 is connected to the middle end of the annular tube 118 . The arc-shaped elbow 120 extends outward and passes through the flow meter 103 .

[0028] It is worth noting that the flow meter 103 is a flow rate temperature monitor, and detects the temperature of the temperature-control liquid flowing through the arc elbow 120 through a temperature detector.

[0029] Furthermore, the outer end faces of the temperature control pipes 107 on both sides are provided with support plates 106 for supporting effect, and one end face of the support plate 106 is provided with a flow rate valve 111, which is connected to the temperature control pipe 107 and adjusts the on-off condition of the temperature control pipe 107.

[0030] Furthermore, flow rate temperature monitors are provided in the support plates 106 on both sides, and the temperature of the temperature-controlling liquid flowing through the temperature-controlling pipes 107 on the upper and lower sides is detected by the temperature detector.

[0031] Furthermore, support columns 108 are fixedly provided on the end surfaces of the upper and lower support plates 106 close to one side, and exhaust fans 109 are fixedly provided between the support columns 108 . An exhaust cavity 112 opening outward is provided in the exhaust fan 109 .

[0032] Furthermore, a power shaft 119 is rotatably provided on one side wall of the discharge chamber 112 , and a rotating fan 114 arranged in a ring is fixedly connected to the outer end surface of the power shaft 119 .

[0033] Furthermore, a power motor 115 is fixedly disposed in a side wall of the discharge chamber 112 , and one end of a power shaft 119 is power-connected to the power motor 115 .

[0034] It is worth noting that the power motor 115 is started and drives the power shaft 119 to rotate, and then the rotation of the power shaft 119 drives the rotating fan 114 to rotate, thereby achieving the effect of wind output.

[0035] Furthermore, an inclined discharge pipe 105 is provided between one side of the outer end surface of the discharge fan 109 and the control valve 104 , and one end of the discharge pipe 105 is connected to the discharge chamber 112 .

[0036] When using this solution, first drive the support base 101 to move as a whole to the working position, and connect it to the temperature control liquid pipe through both ends of the temperature control pipe 107, and adjust the flow rate valve 111 at the upper and lower ends to adjust the input flow of the temperature control liquid.

[0037] At this time, after the acid dye production waste gas is input into the processing chamber 117, the temperature control liquid is input through the side annular tube 118, and the temperature in the processing chamber 117 is maintained at a suitable processing temperature of the acid dye production waste gas, and the acid dye production waste gas is purified by the waste gas purification device, and the purified waste gas is output upward to the control valve 104, and then the centralized waste gas is collected, and the waste gas is tested and meets the standards, and then output to the exhaust fan 109 through the exhaust pipe 105. At this time, the power motor 115 starts and drives the power shaft 119 to rotate, and then the rotation of the power shaft 119 drives the rotating fan 114 to rotate, and the effect of wind output is achieved, thereby driving the treated purified waste gas in the exhaust pipe 105 to flow outward and output, thereby achieving the effect of waste gas purification and emission.

[0038] During this process, the flow rate and temperature of the discharge pipe 105 and the arc-shaped bend pipe 120 are monitored through the support plate 106 and the flow meter 103. If the detection temperature difference of the flow rate temperature monitors on the three sides is large, it means that the temperature of the internal acid dye production waste gas has changed due to the reaction. At this time, the speed of the power motor 115 can be controlled and the speed of the rotating fan 114 can be changed through the temperature control signal transmission adjustment, so that when the waste treatment reaction in the treatment chamber 117 is intense, the discharge rate of the treated waste gas can be reduced, and sufficient purification reaction time can be given to the internal treatment chamber 117, thereby improving the purification efficiency of the acid dye production waste gas.

[0039] 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.
