Description
Technical Field
The invention relates to an incinerator for incinerating all solid wastes including household garbage, general industrial wastes and the like, in particular to a detachable multi-column middle fixing and middle mechanical compensation device of the solid waste incinerator, wherein one end is a middle fixing end, the other end is a middle mechanical compensation end, and the two ends are mutually independent and mutually combined, can be mutually independent and detached and can be combined into a whole. The fire grate is a real modularized foundation and is also a key for ensuring the normal and stable operation of the fire grate of the large-scale incinerator.
Background
In the incinerator, because of the difference between the surface temperature of the fire grate and the temperature of the framework, a thermal expansion absorption device is required to be considered for ensuring the normal operation of the equipment. Throughout the life of incinerators, there are generally the following methods of treating this thermal expansion:
1. Thermal expansion self-absorption type:
One of the two fire grate sheets is that each fire grate sheet is independently fixed on a bracket, and thermal expansion gaps are reserved respectively, but the problems that the design of the whole bracket is very complex and the like are brought;
In addition, the total thermal expansion gaps are reserved at the two ends of a single row, so that the space requirement caused by thermal expansion generated after the fire grate is heated to a certain furnace temperature is met, but the phenomena of combustion short circuit and the like generated by furnace temperature change in the whole operation cannot be ensured.
2. Spring compensation type:
for example, a side compensation device of the household garbage incinerator with the patent number 021111455.2 compresses fire grate segments through springs to compensate; due to the complexity of the components of the garbage entering the furnace, the phenomena of high-temperature failure of the spring and the like caused by local overheating of the fire grate sheets due to combustion short circuit in the running process are difficult to avoid;
In addition, as for example, the middle-row thermal expansion absorption device of the multiple rows of the fire grate of the garbage incinerator in Chinese patent ZL 2012 2 0421151.0 utilizes the cross fork-shaped compression bar and the spring force to enable the compensation block to be always attached to the fire grate to absorb the expansion amount of the fire grate, thereby ensuring the normal operation of the incinerator; the spring is arranged in a high temperature area far away from the fire grate segment so as to avoid the occurrence of high temperature failure phenomenon and the like. But it also has the following disadvantages: when the device is used for incinerating garbage, particularly unsorted garbage, sundries such as wedge, iron nails, steel balls and the like are difficult to avoid in the garbage, and if the sundries are embedded between the fire grate and the compensation block once, the problems of short combustion, local overheating of fire grate pieces and the like are caused, so that the effect of the compensation device that the ventilation gap of the fire grate is constant is directly influenced; and it is arranged between two columns, and true modularization and the like cannot be realized.
3. Mechanical compensation type:
The mechanical compensation device of the incinerator fire grate of patent number 200710157198.4 adopts a mechanical mode, so that the fire grate pieces and the middle compensation block are always in contact at any time and temperature, and the phenomena of combustion short circuit and foreign matter embedding in the operation process are avoided. And the practical engineering test shows that the application effect is very ideal, but the method is only suitable for side compensation at present.
Because of the specificity of the fuel of the incinerator, the components of the incinerator-entering incineration are very complex, and the manufacturing and installation requirements of the incinerator are very high; although the manufacturing unit can ensure the manufacturing quality, the installation unit cannot ensure the installation quality due to lack of experience, so that components requiring the installation precision (such as middle fixing and middle mechanical compensation devices between two groups of transversely adjacent fixed grates) are all positioned and completed in a factory, modular manufacturing is realized, and then the components are integrally transported to site for installation; only then, the installation quality of the fire grate can be guaranteed, the construction period of the site is shortened, and the safe and stable operation of a plurality of rows of large fire grates is guaranteed. Therefore, how to provide the key parts of the incinerator, which can realize modularized manufacture and ensure field installation quality, is a problem to be solved in the technical field.
