Description

Technical Field

[0001] This utility model mainly relates to the field of cement production technology, specifically a feeding pipe for a cement production decomposition furnace. Background Technology

[0002] In cement production, traditional fuels are mainly fossil fuels such as coal. The combustion process typically involves transporting the fuel to specific combustion equipment (such as a rotary kiln) for combustion to provide heat for the calcination of cement clinker. Tertiary air ducts play a crucial role in the cement production system, primarily transporting hot air to provide secondary air for fuel combustion within the kiln, while also regulating airflow and temperature distribution within the kiln. With rising energy prices and the gradual depletion of resources, production costs are constantly increasing. Furthermore, the combustion of fossil fuels produces large amounts of greenhouse gases such as carbon dioxide, placing significant pressure on the environment.

[0003] Although some alternative fuels (such as biomass fuel and waste fabric) are being gradually introduced into the market, the physical and chemical properties of alternative fuels are quite different from those of traditional fuels. Their combustion characteristics and calorific value are unstable, which poses many challenges to their introduction into existing cement production processes.

[0004] Currently, existing tertiary air duct systems are mainly designed for the combustion and air supply needs of traditional fuels. Their structure is relatively simple, and they use independent feeding pipes for individual feeding. However, when trying to introduce alternative fuels using existing tertiary air duct systems, problems such as mismatch between the airflow and the tertiary air duct, unstable combustion, feed blockage, and low utilization efficiency of alternative fuels may occur, which can easily affect the stable operation of the decomposition furnace and the quality of cement clinker products. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding pipe for a cement production decomposition furnace, achieved through the following technical solution:

[0006] A feeding pipe for a cement production decomposition furnace includes a first pipe, a horizontally arranged second pipe fixedly installed at the lower part of one side of the first pipe, an inclined first discharge pipe fixedly installed on the outside of the first pipe, and a second discharge pipe fixedly installed at the top of the second pipe.

[0007] Furthermore, the angle between the first feed pipe and the horizontal plane is α, where α is 152°.

[0008] Furthermore, the second feed pipe includes:

[0009] A vertical feeding pipe is provided, and a pipe interface is integrally fixedly installed on the top of the second pipe, with the vertical feeding pipe fixedly installed at the upper end of the pipe interface.

[0010] The connecting pipe is integrally fixedly installed at the upper end of the vertical feeding pipe and is inclined.

[0011] Furthermore, a horizontal tube is fixedly installed at the upper end of the connecting tube, and the horizontal tube communicates with it.

[0012] Furthermore, both the first and second pipelines are equipped with gate valves, which are controlled by a DCS control system.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This feeding pipe is designed for use in the decomposition furnace in cement production. When feeding alternative fuel, the alternative fuel can be directly fed into the first and second feeding pipes through the first and second feeding pipes. This allows the fuel to mix quickly with air and solves the problems of unstable combustion, blockage, and uneven combustion caused by the difference in combustion characteristics and calorific value between traditional fuels and alternative fuels.

[0015] 2. By improving the design of the feeding pipes, the fuel can be more evenly distributed into the first and second feeding pipes and mixed with air before entering the decomposition furnace. This allows the fuel to be fully mixed with hot air, thereby improving combustion efficiency. This not only helps to improve the calcination quality of cement clinker but also reduces the loss of incompletely burned fuel.

[0016] 3. The inclined first feed pipe and the vertically fed second feed pipe ensure smooth fuel delivery and effectively reduce clogging issues. This not only improves production efficiency but also reduces maintenance costs. Attached Figure Description

[0021] Example: A feeding pipe for a cement production decomposition furnace

[0022] like Figure 1-2 As shown, a feeding pipe for a cement production decomposition furnace has the following specific structure:

[0023] A first pipe 10 is fixedly installed on the lower part of one side of the first pipe 10, and a horizontally arranged second pipe 20 is fixedly installed on the outer side of the first pipe 10. A first feed pipe 40 is fixedly installed at an angle, and a second feed pipe 40 is fixedly installed on the top of the second pipe 20. This feed pipe is designed for use in the decomposition furnace in cement production, and is particularly optimized for the feeding of alternative fuels to solve problems such as unstable combustion, blockage, and uneven combustion caused by the differences in combustion characteristics and calorific value between traditional fuels and alternative fuels.

[0024] The first feed pipe 40 forms an angle α with the horizontal plane, where α is 152°. This angle design has been verified to ensure smooth delivery of alternative fuels without affecting the feed process, while optimizing the mixing of fuel and air and improving combustion efficiency.

[0025] The second feeding pipe 30 includes: a vertical feeding pipe 301, with a pipe interface 201 integrally fixedly installed at the top of the second pipe 20, and the vertical feeding pipe 301 fixedly installed at the upper end of the pipe interface 201; a connecting pipe 302, with an inclined connecting pipe 302 integrally fixedly installed at the upper end of the vertical feeding pipe 301; and a horizontal pipe 303, with a horizontal pipe 303 connected to the connecting pipe 302 fixedly installed at the upper end. The vertical feeding pipe 301 allows for smoother feeding, optimizes the fuel feeding method, improves the mixing effect of fuel and air, increases combustion efficiency, reduces clogging and uneven combustion problems, and helps prevent clogging. The horizontal pipe 303 is designed to facilitate connection with alternative fuel supply systems, ensuring a stable fuel supply.

[0026] Both the first pipe 10 and the second pipe 20 are equipped with gate valves, which are controlled by a DCS control system. The addition of gate valves and the DCS control system makes fuel delivery more precise and improves safety during commissioning, preventing leakage and fire.

It is used in conjunction with a motherboard, memory modules, storage media, and power supply, which is AC power or a lithium battery. When a display screen is provided, a graphics card is also included.
