Description

Technical Field

[0001] This utility model relates to the field of steam heat transfer technology for primary drying chambers used in the production of denitrification catalysts, specifically to a steam heat transfer device for primary drying chambers used in the production of denitrification catalysts. Background Technology

[0002] The denitrification catalyst is the core component of SCR technology, determining the denitrification efficiency and economy of the SCR system. Its construction cost accounts for over 20% of the total cost of flue gas denitrification projects, and its operating cost accounts for over 30%. In recent years, developed countries such as the United States, Japan, and Germany have continuously invested significant human, material, and financial resources in researching and developing high-efficiency, low-cost flue gas denitrification catalysts, emphasizing intellectual property protection in catalyst patent technology, technology transfer, and production licensing processes. Initially, catalysts were metal catalysts such as Pt-Rh and Pt, using monolithic ceramic supports such as alumina. These catalysts exhibited high activity and low reaction temperatures, but their high price limited their application in power plants. Therefore, starting in the late 1960s, three Japanese companies—Hitachi, Mitsubishi, and Takeda Chemical—developed TiO2-based catalysts through continuous research and development, gradually replacing Pt-Rh and Pt series catalysts. The components of this type of catalyst are mainly composed of metal oxides such as V2O5 (WO3), Fe2O3, CuO, CrOx, MnOx, MgO, MoO3, and NiO, or mixtures that act in combination. They are usually supported by TiO2, Al2O3, ZrO2, SiO2, activated carbon (AC), etc., and undergo reduction reactions with reducing agents such as liquid ammonia or urea in the SCR system. This has made it the mainstream catalyst product for SCR denitrification projects in power plants.

[0003] The existing steam heat transfer device for the primary drying chamber used in the production of denitrification catalysts is not convenient for uniformly transporting hot gas, resulting in fluctuating temperatures in the drying chamber, which is inconvenient to use. Furthermore, the existing steam heat transfer device for the primary drying chamber used in the production of denitrification catalysts is not convenient for controlling the intake and exhaust of air, requiring intermittent control, which makes it impractical.

[0015] This invention provides a steam heat transfer device for a primary drying chamber used in the production of denitrification catalysts, which has the following advantages:

[0016] 1. This steam heat transfer device for a primary drying chamber used in the production of denitrification catalysts, through the setting of a gas delivery tank, facilitates the uniform delivery of hot gas, thereby creating a fluctuating temperature effect within the drying chamber. The device is configured with a gas delivery tank, gas storage tank, sliding trough, sliding extrusion plate, push slide, push rod, rotating frame, support, rotating shaft, driven pulley, belt, motor base, drive motor, and drive pulley. During operation, when gas delivery is needed, the drive motor is activated. The output of the drive motor drives the drive pulley to rotate, which in turn drives the driven pulley via the belt. The driven pulley drives the rotating shaft to rotate within the support, which in turn drives the rotating frame. The rotating frame then drives the push rod, which in turn drives the sliding extrusion plate to slide within the sliding trough via the push slide. The sliding extrusion plate delivers the hot steam from the gas storage tank into the gas delivery pipe through a connecting pipe, thus achieving a good delivery effect and convenient operation.

[0017] 2. The steam heat transfer device for the primary drying chamber used in the production of denitrification catalyst, through the setting of a closing plate and a displacement switch plate, enables convenient control of air intake and exhaust without the need for intermittent control. Through the coordinated arrangement of a water tank, heater, heating wire, exhaust pipe, first control box, chute, closing plate, transition pipe, connecting pipe, air supply pipe, mounting base, return pipe, support frame, lead screw, motor frame, servo motor, push base, push frame, fixed base, second control box, displacement chute, displacement switch plate, push frame, branch pipe, load-bearing frame, and air supply pipe head, during operation, when air intake is needed, the heater is turned on, and the heater energizes the heating wire through an electric wire. The energized heating wire generates a large amount of heat, simultaneously heating the water inside the water tank. The water is heated, and the continuously heated water will produce steam. The steam enters the first control box through the exhaust pipe, then the servo motor is started. The output of the servo motor drives the lead screw to rotate inside the support frame. The lead screw drives the push seat to move, and the push seat drives the push frame and the pusher frame to move respectively. The pusher frame drives the closing plate to slide out inside the slide groove, allowing the steam to flow into the transition pipe through the first control box. The steam inside the transition pipe flows into the air supply tank. The pusher frame drives the displacement switch plate to slide inside the displacement groove, causing the second control box to close, preventing steam from flowing into the branch pipe through the air supply pipe. When air supply is needed, the servo motor is started to reverse, thereby closing the first control box and opening the second control box, thus achieving a good control effect and achieving a highly practical purpose.
