Abstract
Description
Technical Field
[0001] The utility model relates to a grate, in particular to a roof truss type combined V-shaped fixed grate. Background Art
[0002] In the current incinerator application field, traditional grate designs mostly adopt a single grate structure, and the grate shape is relatively simple. This design has gradually exposed several key problems in practice, which is in sharp contrast to the demand for improving incinerator performance.
[0003] First, when burning coal lumps and solid waste, the single-grate structure makes it difficult to ensure that the incinerated materials are contained within the furnace. This results in incomplete combustion of some materials, resulting in a large amount of unburned harmful substances, which directly affects the environmental performance and combustion efficiency of the incinerator. This is contrary to our goal of efficient and clean combustion.
[0004] Secondly, the uniform grate shape limits the efficiency of air circulation and the uniformity of coal or steam-generating waste combustion. During the combustion process, poor air circulation leads to incomplete combustion, while uneven accumulation of the incinerated material on the grate can cause localized overheating or insufficient combustion, further reducing thermal efficiency and incinerator stability.
[0005] Furthermore, due to design limitations, these traditional grates exhibit poor adaptability when processing different types and characteristics of solid waste. The development of modern incineration technology requires grates to flexibly respond to diverse waste treatment needs, and traditional grates are clearly unable to meet this requirement.
[0006] Finally, from an operation and maintenance perspective, the design of traditional grates also presents numerous inconveniences. Incomplete combustion can lead to slagging and ash accumulation, making cleanup more difficult. Wear and damage to the grates themselves can also threaten the incinerator's stable operation, increasing maintenance costs and downtime.
[0007] In summary, the traditional single-grate and single-shaped grate design can no longer meet the needs of the development of modern incinerator technology.
[0008] Therefore, it is necessary to develop a special innovative grate structure, such as a unitized roof truss grate, and assemble multiple unitized roof truss grates in a row. According to the daily incineration output, multiple unitized roof truss grates can be combined into one, forming a row of fixed grates. When building a combined incinerator, the unitized roof truss grates can be combined into a row of fixed grates.
[0009] When building an incinerator, it can be assembled into a V-shaped fixed grate. According to the daily incineration output, the V-shaped fixed grate can be arranged into 1 or 2 combined V-shaped fixed grates. If the daily incineration output is small, one combined V-shaped fixed grate can be installed. If the daily incineration output is large, two combined V-shaped fixed grates can be installed.
[0010] 1-2 Combined V-shaped Fixed Grate. The uniquely designed roof-truss combined V-shaped fixed grate structure and shape are designed to virtually expand the effective combustion surface of the grate during incineration operation. The continuous combined roof-truss arrangement allows for timely ash removal, facilitates oxygen permeability, and generates exceptionally strong firepower. Improving the incinerator's combustion efficiency, significantly enhancing full combustion, improving combustion stability and environmental performance, while simplifying operation and maintenance procedures are pressing challenges in the current incinerator technology landscape. Utility Model Content
[0011] The technical problem to be solved by the utility model is to provide a roof truss type combined V-shaped fixed grate.
[0012] The technical problem to be solved by the present invention is achieved by the following technical solutions:
[0013] A roof truss type combined V-shaped fixed grate is composed of multiple unitized roof truss type grates combined into a row as a basic grate, and the unitized roof truss type grates are arranged and combined in the form of multiple adjacent roof truss type fixed grates. The grate is roof truss type, and the distance between adjacent grates is set at 50mm.
[0014] The grate is provided with a grate gap.
[0015] The width of the unitized roof truss grate is set between 700-800 mm.
[0016] The height of the unitized roof truss grate is set between 550-800 mm.
[0017] After the plurality of unitized roof truss-type grates are arranged and combined in an adjacent roof truss-type fixed row, the overall width thereof is set between 1000-10000 mm, and the length thereof is set between 1000-6000 mm.
[0018] The beneficial effects of the utility model are:
[0019] Improve combustion efficiency: The roof-truss design forms multiple slopes on the grate surface, which is conducive to the accumulation of coal blocks or garbage on the grate to bear the pressure of five meters deep materials. However, during the high-temperature incineration operation at thousands of degrees, combined with the continuous incineration or slag discharge of the incinerated materials, the burning materials from top to bottom naturally slide down along the roof-truss grates on both sides and rub to discharge the dead ash in time, which is easy to oxygenate and promote combustion, making the combustion more complete, significantly improving the combustion efficiency of the incinerator and ensuring that the slag thermal loss rate is ≤5‰.
[0020] Enhanced stability: The unitized roof-truss grate is a combination of multiple units combined into one in an adjacent fixed arrangement, which enhances the stability of the entire grate structure, reduces deformation or damage caused by high temperature and mechanical stress, extends the service life of the grate, and ensures the stable operation of the incinerator.
[0021] Optimize thermal efficiency: The reasonable setting of the grate gap and the roof-type grate structure promote the circulation of air between the grates, which helps to supply oxygen during the combustion process and improve the combustion efficiency. It also helps to evenly distribute and transfer heat, further improving the thermal efficiency of the incinerator.
[0022] Improve adaptability: The grate design is flexible, and the number, width and height of the grates can be adjusted according to the actual needs of the incinerator to adapt to the treatment of different types and quantities of solid waste, thereby enhancing the adaptability and flexibility of the incinerator.
[0023] Simplified operation and maintenance: The structure of the roof-truss combined fixed grate is relatively simple, which reduces complex mechanical components and reduces the difficulty of operation. At the same time, the modular design of the grate is also convenient for maintenance and replacement, reducing maintenance costs and time. BRIEF DESCRIPTION OF THE DRAWINGS
