High-calorific-value household garbage incineration water-cooling grate furnace

Abstract

The invention discloses a high-calorific-value household garbage incineration water-cooling fire grate furnace which comprises a movable fire grate segment set, a fixed fire grate segment set and a motion compensation device. A plurality of fixed connecting pieces are arranged at the upper ends of the two fixed fire grate frames in the length direction of the fixed fire grate frames, the corresponding positions of the movable fire grate frames penetrate through the lower portions of the corresponding fixed connecting pieces respectively, and a plurality of movable connecting pieces are arranged at the upper ends of the movable fire grate frames in the length direction of the movable fire grate frames. The fixed connecting pieces and the movable connecting pieces are alternately distributed at intervals, fixed fire grate segment sets are arranged on the fixed connecting pieces, and movable fire grate segment sets are arranged on the movable connecting pieces; a movable water cooling pipeline is arranged between the front wall plate and the rear wall plate, the movable water cooling pipeline moves along with the movable fire grate frame and conducts water cooling on the movable fire grate segment sets, a motion compensation device is arranged at the rear end of the movable water cooling pipeline, and displacement compensation is conducted through the motion compensation device. The surface temperature of the water-cooling fire grate segment in the actual operation process is effectively controlled, and the water-cooling fire grate segment can deal with incineration treatment of high-calorific-value household garbage.

Description

technical field [0001] The invention relates to the field of domestic waste incinerators, in particular to a water-cooled grate furnace for high calorific value domestic waste incineration. Background technique [0002] During the incineration process of domestic waste incinerators, the deformation and burning of grate pieces are common. For the cooling of the grate, the traditional way is to use forced air cooling, with air as the cooling medium, and the primary air is blown in from the bottom of the grate or from the gap to achieve the cooling effect. The operating data shows that the economical use temperature of the grate surface is 400 ℃ ~ 500 ℃. In the face of the high calorific value garbage and the cooling stability of the grate, the traditional air cooling is difficult to cope with. [0003] In order to adapt to wastes with various calorific values, especially wastes with high calorific value, domestic mainstream domestic waste incinerator companies have successive...

Problems solved by technology

The operating data shows that the economical use temperature of the grate surface is 400°C~500°C. In the face of high calorific value garbage and the cooling stability requirements of the grate pieces, traditional air cooling is difficult to cope with

[0003] In order to adapt to wastes with various calorific values, especially wastes with high calorific values, domestic mainstream household waste incinerator companies have successively carried out research and development of water-cooled grates, but in In the pouring and forming process of the grate piece, it is difficult to overcome the air holes or cracks inside the casting; in addition, during the reciprocating horizontal movement of the movable grate frame, the cooling water pipe is easy to shift accordingly. If the rigid cooling water pipe is used, it will Destruction due to movement deflection of the movable grate holder
