Problems solved by technology

[0005] The grate pieces of the existing mechanical grate do not have the function of water cooling, and the fuel adaptability is poor. When burning fuel with a higher calorific value, such as biomass, the surface temperature of the grate piece will be as high as four to five degrees
Increase the frequency of grate replacement, which in turn affects the operating costs and economic benefits of domestic waste incineration plants

Embodiment Construction

[0020] Such as figure 1 , figure 2 with image 3 As shown, the water-cooled grate body 1 is cast, and the cooling water pipe 2 is included in the water-cooled grate 1 during the casting process. There is an extension of the cooling water pipe at the bottom of the grate, and the water inlet joint 3, the water outlet joint 4 and through The stainless steel connecting pipe 6 is responsible for connecting the two connecting joints 5 of the double U-shaped cooling water pipes. During operation, water is supplied by the circulating cooling water system, and the external water pipe is connected to the water inlet joint 3 and the water outlet joint 4. At the same time, the stainless steel connecting pipe 6 is connected to the interface 5. The water flows in from the water inlet and flows into the cooling water pipe in the grate. The large U-shaped pipe flows into the smaller U-shaped pipe through the connection interface 5 and the stainless steel connecting pipe 6, and finally flow...

Abstract

The invention relates to the field of incineration, in particular to a water cooling fire grate segment applied to a fire grate of an incinerator. A water cooling fire grate segment body is formed bycasting, cooling water pipes are embedded in the water cooling fire grate segment body, and the cooling water pipes are used as a water cavity in a fire grate segment; one ends of the cooling water pipes of the fire grate segment are provided with a water inlet and a water outlet, and pipe joints are welded on the ends to facilitate connection with a cooling water system; and two connecting portsat the other ends of the cooling water pipes of the fire grate segment are connected through a connecting pipe, so that cooling water can circulate in the water cavity of the fire grate segment. According to the water cooling fire grate segment applied to the fire grate of the incinerator, the surface temperature can be decreased below 250 degree centigrade, so that the service life of the fire grate segment is prolonged by more than 5 years, the maintenance period is prolonged by more than 20%, and the operating cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of incineration, in particular to a water-cooled grate piece applied to the grate of an incinerator. Background technique [0002] Due to the different types of waste, it can be divided into domestic waste, high calorific value domestic waste, industrial waste, medical waste, biomass waste, etc. Among them, the calorific value of domestic waste is low. At present, mechanical grate furnaces have gradually occupied the leading position in domestic waste incineration due to their strong adaptability, reliable operation and high controllability. [0003] The traditional mechanical grate furnace is mainly air-cooled. The primary air is blown into the furnace by the ash hopper under the grate. When the primary air stays at the bottom of the grate, the labyrinth arrangement structure at the bottom of the air-cooled grate serves as a diversion The role is to guide the primary air to cool the surface temperature of the grate ...
