Description
本发明涉及焚烧设备领域，具体涉及一种应用在垃圾焚烧炉的水冷炉排。The invention relates to the field of incineration equipment, in particular to a water-cooled grate applied to a garbage incinerator.
对于垃圾焚烧炉，伴随着二恶英抑制的观点，燃烧室烟气高温化已成为一种趋势。现今推崇的低空气比高温燃烧也正是满足了焚烧高效化、低公害化的要求，而且对高热值垃圾焚烧的需求，高温化也是绕不开的话题。在这样的工况下，为了追求焚烧炉的高耐久性，水冷化技术必不可少。With regard to garbage incinerators, with the viewpoint of dioxin suppression, the high temperature of the flue gas in the combustion chamber has become a trend. The low-air-to-high-temperature combustion that is highly regarded today meets the requirements of high-efficiency and low-pollution incineration, and the need for high calorific value waste incineration, high-temperature is also an unavoidable topic. Under such conditions, in order to pursue the high durability of the incinerator, water cooling technology is essential.
由于垃圾的种类不同，可分为一般生活垃圾、高热值生活垃圾、工业垃圾、医疗垃圾、生物质垃圾等。其中一般生活垃圾热值较低，目前机械炉排炉以其适应性强、运行可靠，可控性高等特点，已逐渐占据生活垃圾焚烧设备的主导地位。Due to different types of waste, it can be divided into general household waste, high calorific value household waste, industrial waste, medical waste, biomass waste, etc. Among them, the general domestic waste has a low calorific value. At present, the mechanical grate furnace has gradually occupied the leading position of domestic waste incineration equipment due to its strong adaptability, reliable operation, and high controllability.
传统的机械炉排炉以空冷为主，一次风由炉排下一次风灰斗吹入炉膛内，一次风在炉排底部停留时，炉排片底部的迷宫布置结构起到导流作用，引导一次风冷却炉排片表面，降低温度，防止炉排烧损。The traditional mechanical grate furnace is mainly air-cooled, and the primary air is blown into the furnace chamber by the next air ash hopper of the grate. The surface of the grate is cooled by air to reduce the temperature and prevent the grate from burning.
但空冷机械炉排炉的冷却效果有限，并不适用于热值较高的其他垃圾焚烧。However, the cooling effect of the air-cooled mechanical grate furnace is limited, and it is not suitable for other waste incineration with higher calorific value.
因此为了使机械炉排炉在热值较高的高热值生活垃圾、工业垃圾、医疗垃圾及生物质垃圾焚烧中也有用武之地，水冷设计已成为一种趋势。水冷炉排对于垃圾热值的适应性更强，使多种垃圾掺烧成为一种可能，从而增加经济效益。Therefore, in order to make mechanical grate furnaces also useful in the incineration of high-calorie domestic waste, industrial waste, medical waste, and biomass waste with high calorific value, water-cooled design has become a trend. The water-cooled grate is more adaptable to the calorific value of garbage, making it possible to mix various kinds of garbage, thereby increasing economic benefits.
在生物质垃圾焚烧领域，水冷振动炉排技术已应用的非常广泛。其水路布置方法，如图1所示是现有技术中水冷振动炉排水路示意图。冷却水由进水口1进入前水冷集箱3，再流向各纵向水冷管4，通过热对流及热传导的方式降低炉排表面温度。以避免炉排超温，造成炉排的烧损，同时保证燃料充分及高效的燃烧和炉渣的顺利排出。再由各水冷管4流向后水冷集箱5，最后由出水口2流出。In the field of biomass waste incineration, water-cooled vibrating grate technology has been widely used. The waterway layout method is shown in FIG. 1 as a schematic diagram of the waterway of the water-cooled vibration furnace in the prior art. The cooling water enters the front water-cooling header 3 from the
现有水冷振动炉排在生物质燃烧领域能有效防止炉排过烧，但由于进、出水口分别在整个炉排区域的左上和右下(或者右上和左下)布置，类似对角线的布置方式，实际应用过程中，会到导致左右炉排表面存在温差，燃料燃烧不均， 存在烧不透或过烧的情况发生，而降低总体效率。同时生活垃圾焚烧水冷炉排与水冷振动炉排结构上的差异，使之不能完全在水冷炉排上得以实施。The existing water-cooled vibrating grate can effectively prevent overfire of the grate in the field of biomass combustion, but since the water inlet and outlet are arranged on the upper left and lower right (or upper right and lower left) of the entire grate area, similar to the diagonal arrangement In the actual application process, there will be a temperature difference between the left and right grate surfaces, uneven fuel combustion, and impervious or over-burning, which reduces the overall efficiency. At the same time, the differences in the structure of the domestic waste incineration water-cooled grate and the water-cooled vibrating grate prevent it from being fully implemented on the water-cooled grate.

The water inlet and outlet directions of the fixed grate and the movable grate are opposite, and they are respectively connected to two water channels connected by the grate water chamber.
活动炉排的进、出水集箱固定在活动炉排的驱动梁上。The inlet and outlet water collecting tank of the movable grate is fixed on the driving beam of the movable grate.
炉排片可以采用铸造水腔，也可以在炉排片预埋水管。The grate plate can use a casting water cavity, or a water pipe can be embedded in the grate plate.
水冷炉排片下部设置有热电偶，测量炉排表面温度，由温度数据判断炉排表面的垃圾燃烧情况，通过调节炉排运行速度和冷却水量，达到均匀燃烧。The lower part of the water-cooled grate plate is provided with a thermocouple, which measures the surface temperature of the grate, judges the burning situation of garbage on the surface of the grate from the temperature data, and adjusts the operating speed of the grate and the amount of cooling water to achieve uniform combustion.

When a single row of cooling water leaks, the single row can be cooled by air. Instead, it does not affect the operation of the entire grate system; the built-in water channel optimizes the cooling effect, and the corrosion resistance of the grate piece ensures the stable operation of the entire circulating water system; the longitudinal arrangement of the M-shaped water cavity makes the cooling water inside the grate piece The residence time is longer, and the cooling effect of the entire surface of the grate is more uniform; efficient cooling makes the grate able to withstand higher calorific value fuel, which can be adapted A variety of high calorific value garbage mixed burning; compared with air-cooled grate, the air used for cooling grate pieces is reduced, which is more suitable for low air ratio combustion to reduce flue gas emissions; the surface temperature of the grate pieces is reduced to below 250 degrees Celsius, so that the life of the grate pieces It has been upgraded for more than 5 years, and the maintenance period has been extended by more than 20%, which has greatly reduced operating costs.
