Ash cooling machine

Abstract

The invention discloses a cold ash machine which comprises a cold ash machine body and a cooling system, wherein the cold ash machine body comprises an ash inlet part, a machine body and an ash discharging part; a heat exchanging chamber is formed in the machine body; ash dregs to be cooled can enter the machine body through the ash inlet part, and then are discharged by the ash discharging part;the cooling system is used for absorbing heat, and also comprises a fluidizing wind-inlet system; the fluidizing wind-inlet system comprises a wind chamber which can be communicated with a wind source; the wind chamber is positioned on the lower part of the heat exchanging chamber, and a wind distributing plate is arranged between the wind chamber and the heat exchanging chamber; the wind distributing plate is provided with wind distributing holes passing through the wind chamber and the heat exchanging chamber; and the upper part of the heat exchanging chamber is provided with a wind outlet.The optimized technical scheme is as follows: the wind chamber is divided into a plurality of wind separation chambers by a plurality of vertical wind chamber separation plates; and the plurality of wind separation chambers are respectively communicated with a plurality of wind inlet pipes. The cold ash machine can fluidize ash dregs, makes cold air and ash dregs carry out strong heat exchange, fast reduces the temperature of the ash dregs, and improves the cooling effect of the cold ash machine.

Description

technical field [0001] The invention relates to an ash cooling mechanism, in particular to an ash cooling machine for cooling ash. Background technique [0002] Currently, in the use of boilers, a large amount of ash is generated. During normal shutdown, if the ashes as high as 900 degrees are not released, it will take a long time to cool down the furnace temperature, resulting in prolonged shutdown time; when the furnace is shut down in an accident and emergency repairs are required, the cooling speed needs to be accelerated. The ashes must be drained. For the released ash, there is not only nowhere to pile up; even if there is a place to store it, it is very dangerous because of its high temperature; moreover, high temperature ash will release sulfide and nitride, causing environmental pollution. In addition, in view of the serious global energy problems, the shale oil refining industry is also developing continuously, and the amount of ash generated in the shale oil re...

Problems solved by technology

[0006] Although the above-mentioned cold ash machine can reduce the temperature of the hot ash, because the hot ash passes through the pipe 03 under the action of gravity, the speed of the hot ash passing through the pipe 03 cannot be controlled, so the passing speed of the ash cannot be adjusted according to the actual situation. Adjustment, it is difficult to reduce the temperature of the ash to the predetermined temperature
