Description

Technical Field

[0001] This utility model relates to the field of pulverized coal boiler technology, specifically to a pulverized coal boiler furnace combustion optimization device. Background Technology

[0002] Pulverized coal boilers are suspended combustion furnaces that use pulverized coal as fuel. They are widely used in industries such as chemical, papermaking, and textile to provide heat for industrial kilns. With the rapid development of my country's economy and the continuous growth of energy demand, boilers, as important heat energy conversion equipment, are widely used. However, traditional boilers have problems such as low energy utilization and large pollution emissions, which seriously restrict industrial environmental protection and social sustainable development. Therefore, it is necessary to optimize boiler combustion.

[0003] Existing pulverized coal boilers are characterized by complex mechanisms and strong nonlinearity, resulting in problems such as lack of direct monitoring of combustion within the boiler, difficulty in model building, and difficulty in achieving high-precision control. In order to achieve digital monitoring of boiler combustion conditions, and thus conduct research on boiler combustion optimization strategies and precise control, improve boiler combustion efficiency, and ensure efficient and safe boiler production, we propose a pulverized coal boiler furnace combustion optimization device. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a pulverized coal boiler furnace combustion optimization device. This device features a reliable mounting monitoring unit that allows for stable installation on the outside of the boiler furnace. A heat-insulated mounting base is used for the monitoring computer. An industrial camera captures images of the flame inside the furnace through high-temperature explosion-proof glass. The monitoring computer analyzes the flame's combustion status and spectrum, displaying the results on a front-end screen, thus enabling real-time monitoring of the combustion inside the furnace. Combined with relevant combustion theories, this provides a digital basis for combustion diagnosis and optimization. Furthermore, it has a reliable feeding control unit that optimizes the furnace combustion from the feeding end based on the monitoring data from the monitoring computer. The controller adjusts the pulverized coal feeding speed by regulating the motor speed. The controller also adjusts the distance between the two crushing rollers via a hydraulic cylinder, thereby controlling the fineness of the pulverized coal and the combustion effect, ultimately optimizing the furnace combustion and effectively solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combustion optimization device for a pulverized coal boiler furnace, comprising an arc-shaped clamp, a hanging monitoring unit, and a feeding control unit;

[0006] Arc-shaped clamps: There are two, one at the front and one at the back, with the two arc-shaped clamps clamped on the outside of the furnace.

[0007] The mounting monitoring unit includes clamping blocks, bolt fasteners, heat-insulating mounting bases, a monitoring computer, and an industrial camera. Each of the left and right ends of the arc-shaped clamping plate is fixedly connected to a clamping block. The clamping blocks have two bolt through holes, one above the other. Two sets of bolt fasteners are installed between the two corresponding clamping blocks. The shaft of the bolt in the bolt fastener passes through the through hole and is connected to the nut on the rear side. A square mounting slot is opened in the middle of the front end of the arc-shaped clamping plate on the front side. A ceramic heat-insulating mounting base is installed and fixed inside the slot. A high-temperature explosion-proof glass is installed on the outside of the furnace corresponding to the mounting slot. The front end of the heat-insulating mounting base extends outward and a monitoring computer is embedded inside. An industrial camera is set at the rear end of the monitoring computer, with the lens of the industrial camera facing the inside of the furnace.

[0008] Feed control unit: installed on the rear curved clamp.

[0009] The arc-shaped clamps are used to install the entire device on the outside of the boiler. By tightening the bolts on both sides, the two arc-shaped clamps can be secured to the outside of the boiler. The heat-insulating mounting base is used to install the monitoring computer and uses the ceramic properties to block the heat from the furnace body from being conducted to the monitoring computer. The industrial camera captures images of the flame inside the furnace through the high-temperature explosion-proof glass.

By controlling the fineness of the coal powder, the combustion of the coal powder can be adjusted. The retaining rings are used to mount and fix the hydraulic cylinders. The chamfered structure on the inner side of the upper end of the mounting slides allows the falling coal to converge towards the middle side of the crushing rollers.

[0013] Furthermore, the feeding control unit also includes a motor bracket and a second motor. The rear end of the crushing box has two rectangular through holes, left and right. A motor bracket is fixedly connected to the rear end of each mounting slide. The motor bracket extends outward from the rectangular through hole, and a second motor is fixedly mounted at its end.
