Description

Detachable multi-row solid waste incinerator middle fixing and middle mechanical compensation device
Technical Field
The utility model relates to an burn burning furnace for burning all solid waste including domestic waste, general industrial waste etc. specifically is but solid waste burns burning furnace intermediate fixation of multiseriate of split and middle mechanical compensation device, and wherein one end is middle stiff end, and one end is middle mechanical compensation end in addition, and both mutually independent make up again to can mutually independent and split, can make up again and close as an organic wholely. The method is the basis for realizing real modularization of the fire grate and is also the key for ensuring the normal and stable operation of the fire grate of the large-scale incinerator.
Background
In the incinerator, because the difference exists between the surface temperature of the fire grate segment and the temperature of the framework, in order to ensure the normal operation of the equipment, a thermal expansion absorption device must be considered. Throughout home and abroad incinerators, there are generally the following methods for dealing with the thermal expansion:
1. thermal expansion self-absorption type:
one of the methods is to fix each fire grate segment on the bracket separately, and reserve a thermal expansion gap respectively, but simultaneously causes the problems of very complex design of the whole bracket and the like;
in the other method, total thermal expansion gaps are reserved at two ends of a single row to meet the space requirement caused by thermal expansion after the fire grate is heated to a certain furnace temperature, but the phenomena of combustion short circuit and the like caused by furnace temperature change in the whole operation cannot be guaranteed.
2. Spring compensation type:
for example, a lateral compensation device of a household garbage incinerator with patent number 021111455.2 compresses a grate segment by a spring for compensation; due to the complexity of the components of the garbage entering the furnace, the phenomena of high-temperature failure of a spring and the like caused by short combustion circuit and local overheating of a fire grate segment in the operation process are difficult to avoid;
as the middle row of thermal expansion absorption devices of the fire grates of the multi-row garbage incinerator in the Chinese patent ZL 201220421151.0, the compensation block can be always attached to the fire grates by the aid of the cross-fork-shaped pressure lever and the spring force to absorb the expansion amount of the fire grates, and accordingly normal operation of the incinerator is guaranteed; the spring is arranged in a high-temperature area far away from the fire grate segment, so that the high-temperature failure phenomenon is avoided. It has the following disadvantages: when the grate is used for incinerating garbage, particularly unsorted garbage, the garbage is difficult to avoid impurities such as wedges, iron nails, steel balls and the like, and if the impurities are embedded between the grate and the compensation block, the problems of combustion short circuit, local overheating of grate segments and the like are caused, so that the effect of enabling the ventilation gap of the grate to be constant by the compensation device is directly influenced; and it is arranged between two columns, cannot realize true modularization, etc.
3. Mechanical compensation type:
for example, the mechanical compensation device of the incinerator fire grate of patent No. 200710157198.4 adopts a mechanical mode, so that the fire grate segment and the middle compensation block are always kept in contact no matter 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 inspection proves that the application effect is ideal, but the method is only suitable for lateral compensation at present.
Due to the particularity of the incinerator fuel, the components of the incinerated substances entering the incinerator 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 inexperience, so that components (such as an intermediate fixing device and an intermediate mechanical compensation device between two groups of transversely adjacent fixed grates) with the requirement on installation precision are positioned and completed in a factory, modularized manufacturing is realized, and then the whole body is transported to a field for installation; only in this way, the installation quality of the fire grate can be ensured, the construction period of a construction site is shortened, and the safe and stable operation of multiple rows of large fire grates is ensured. Therefore, how to provide the key parts of the incinerator which can realize the modularized manufacture and ensure the field installation quality is a problem to be solved urgently in the technical field of the industry.
