Garbage incinerator and primary air chamber supporting beam cooling system thereof

Abstract

The invention discloses a primary air chamber supporting beam cooling system which comprises a primary air duct communicated between cooling air supply equipment and a primary air chamber of a garbage incinerator and cooling air ducts located in supporting beams of the primary air chamber of the garbage incinerator. The downstream of the primary fan is communicated with a branch air duct; an air outlet of the backflow air duct is communicated with the primary air duct and located on the upstream of an air inlet of the primary fan, all the cooling air ducts are communicated with the downstream of the branch air duct, the backflow air duct is communicated with the downstream of all the cooling air ducts, and all the cooling air ducts are connected in parallel. According to the primary air chamber supporting beam cooling system, the temperature of the supporting beam at the primary air chamber of the garbage incinerator can be stably and efficiently reduced, the supporting beam at the primary air chamber and related equipment such as hydraulic cylinders around the supporting beam are prevented from being overheated, and stable and continuous operation of the garbage incinerator is guaranteed. The invention further discloses the garbage incinerator applying the cooling system.

Description

technical field [0001] The invention relates to the technical field of supporting components of a garbage incinerator, in particular to a cooling system for a supporting beam of a primary air chamber. The invention also relates to a garbage incinerator using the supporting beam cooling system of the primary air chamber. Background technique [0002] Garbage incinerator is a mechanical device that uses layered combustion to incinerate domestic waste. It usually includes a furnace wall with a furnace wall enclosed in the middle, and a grate arranged at the bottom of the furnace, which can drive the grate to move to adjust the work. position of the hydraulic cylinder, etc. A slag hopper is provided below the grate to collect the slag leaked from the grate. Since the combustion air supplied to the combustion of the garbage in the furnace is sent into the furnace through the slag hopper, the combustion air is also called The primary wind, so the slag hopper is also called the p...

AI Technical Summary

Problems solved by technology

Take the supporting steel beam near the hydraulic cylinder of the incinerator as an example. Due to the long-term contact of the supporting steel beam with the primary wind and the heat conduction from the high-temperature flue gas in the furnace, the steel beam near the hydraulic cylinder of the incinerator will The temperature of the supporting steel beam rises, and because the space near the hydraulic cylinder of the incinerator is relatively compact, the air flow is not smooth, and the heat cannot be dissipated in time, which will cause the temperature of the hydraulic cylinder of the incinerator to rise, and the hydraulic cylinder has been exposed to high temperature for a long time. Working in the environment will inevitably lead to failure of the hydraulic cylinder, such as frequent oil leakage from the hydraulic cylinder, which not only affects the structural reliability of the hydraulic cylinder, but also restricts the overall working efficiency of the waste incinerator, which affects the stability and continuity of the waste incinerator. adverse effect on operation
