Description

Technical Field

[0001] The utility model relates to the technical field of denitration catalyst activation, in particular to an auxiliary device for a denitration catalyst module to enter and exit a calcining furnace. Background Art

[0002] During the use of denitrification catalyst, the pores are blocked due to the adsorption and bridging of large particles of fly ash or deposited fly ash. Due to the blockage of the pores, the reactants in the flue gas cannot further enter the inner surface of the catalyst pores, resulting in a decrease in activity. At the same time, the local flue gas velocity is too fast, and the insufficient residence time causes the pressure drop to increase and the wear to increase, resulting in the physical deactivation of the catalyst. Since the flue gas fly ash contains more compounds of elements such as K, Na, P, and As, they react with the active sites of the catalyst accordingly, thereby reducing the number of active sites participating in the denitrification reaction, causing the catalyst to be chemically deactivated.

[0003] During the activation process of the denitration catalyst, drying the denitration catalyst is a necessary step in the activation process. The prior art lacks auxiliary devices for the denitration catalyst to enter and exit the calcination furnace, which makes it very inconvenient for the denitration catalyst module to enter and exit the calcination furnace.

[0027] The longitudinal track 101 disposed at the front end of the calcining furnace is used to deliver the denitration catalyst module 104 to be dried to the trolley 107 at the front transverse track 108, and the trolley 107 is dragged to the trolley 107 by the dragging assembly at the trolley 107, and the trolley 107 is moved to the entrance of the calcining furnace by the first push rod 102 disposed at the front end of the calcining furnace, until the longitudinal track 101 in the calcining furnace is filled with the denitration catalyst modules 104 to be dried.

[0028] The trolley 107 provided at the transverse track 108 at the rear end of the calcining furnace is used to drag the calcined denitration catalyst module 104 to the trolley 107, and move the trolley 107 thereto to the longitudinal track 101 at the rear end of the calcining furnace. The first push rod 102 at the rear end of the calcining furnace pushes it to the longitudinal track 101. In the process of taking out the denitration catalyst module 104 after calcination, the calcined catalyst module is ejected by adding a new uncalcined denitration catalyst module 104.

[0029] Each trolley 107 is rollingly connected to the transverse track 108, and the second driving motor provided at each trolley 107 is used to drive the trolley 107 to slide on the transverse track 108. The receiving track 106 at each trolley 107 is provided in the same type as the longitudinal track 101, and each receiving track 106 is provided at the upper part of the trolley 107, and is used to receive the bracket 103 moved from the longitudinal track 101. The dragging assembly is used to move the bracket 103 supporting the denitration catalyst module 104 from the longitudinal track 101 to the receiving track 106. Specifically, the dragging assembly includes a slide 105, a support and a first drive motor 109. The slide 105 is fixedly connected to the upper part of the trolley 107, the support is slidably connected to the slide 105, the first drive motor 109 is fixedly connected to the support, and the first drive motor 109 provides power for the sliding of the support on the slide 105 through the transmission assembly. The baffle 114 is slidably connected to the support, and the second push rod 111 is used to adjust the height of the baffle 114 to achieve the hanging and release of the bracket 103.

[0030] An optional form of a transmission assembly, the transmission assembly includes a driving wheel 112, the driving wheel 112 is rotatably connected to a support, a rack 115 or a sprocket is provided at the slideway 105, and the driving wheel 112 and the rack 115 or the sprocket are meshed.

[0033] The control switches are used to control the first push rod 102 , the second push rod 111 , the first drive motor 109 , and the second drive motor to perform actions respectively.

[0034] Embodiment 2:

[0035] On the basis of Example 1, in order to prevent the bracket 103 from derailing when moving at each longitudinal rail 101 and each connecting rail 106, each trolley 107 is moved at each longitudinal rail 101, a first sensor is provided at the longitudinal rail 101 in the calcining furnace, a second sensor is provided at each transverse rail 108, and a third sensor is provided at each connecting rail 106.

When in use, when the bracket 103 triggers the first sensor, the first sensor sends a signal to the first push rod 102 at the front end of the calcining furnace, so that the first push rod 102 there stops performing the action. When the trolley 107 triggers the second sensor, the second sensor sends a signal to the second drive motor, so that the second drive motor stops performing the action. When the bracket 103 triggers the third sensor, the third sensor sends a signal to the first drive motor 109, so that the first drive motor 109 stops performing the action.

[0037] The first sensor, the second sensor and the third sensor may be any one of an infrared sensor, a reed switch and a contact switch.

Among them, the communication principle of the control switch can adopt any one of radio frequency, Bluetooth, WiFi, ZigBee, IrDA, and TransferJet.

[0043] Embodiment 5:

[0044] On the basis of any one of Examples 1-4, in order to prevent the power supply lines at the second drive motor and the first drive motor 109 from being worn or entangled when the trolleys 107 and the supports at the trolleys 107 move, a cable tie is provided at the power supply lines of each first drive motor 109 and each second drive motor, wherein the cable tie can be in the form of a tank chain trough.
