Embodiment 1

[0022] Such as Figure 4-8 As shown, a new type of processing equipment for molten fly ash includes an incineration device, a feeding device and a water quenching device; the incineration device includes a rotary kiln 1, a driving part 11 and a support 12; the rotary kiln is installed on the support and can be relatively Because the bracket rotates back and forth, the driving part is a motor purchased on the market. This is the prior art, so it will not be described here; the rotary kiln can rotate under the drive of the motor, and this driving method is also the prior art, so here No need to go into details; among them, the rotary kiln includes a kiln body 10, a heating element 13 and a stepped part 14. The kiln body is opened in a hollow cylindrical structure, and the kiln body is installed in an inclined state, so that the fly ash and slag in the kiln body are easier to flow smoothly. The heating element is installed in the side wall of the kiln body to heat the kiln body, ...

Embodiment 2

[0031] Such as Figure 1-3 As shown, the difference between the present embodiment and Embodiment 1 is: a spray device and a delivery device are installed on the water quenching pool 33; wherein, the spray device includes a spray pipe 34, a spray drive 35 and a nozzle 341; the spray drive is The water pump purchased on the market is an existing technology, so I won’t repeat it here; the jet driving part is bolted in the water quenching tank; one end of the jet pipe is connected with the jet driving part, and a nozzle is installed at the other end, and the nozzle is conical , so that the sprayed water flow has a certain water pressure and greater impact force. The spray pipe is installed in an inclined state, and the angle between the discharge pipe and the discharge pipe is an acute angle. At the same time, the plane where the spray pipe and the nozzle of the discharge pipe are located is an obtuse angle , so that when the slag is discharged from the discharge pipe, the water ...

Abstract

The invention discloses a new treatment equipment for molten fly ash, which includes an incineration device, a feeding device matched with the incineration device and a water quenching device matched with the incineration device; the incineration device includes a A rotary kiln that moves back and forth; the water quenching device includes a material receiving part that is rotatably matched with the rotary kiln, an exhaust pipe arranged on the material receiving part, a discharge pipe arranged on the material receiving part and A water quenching pool connected with the discharge pipe; the water quenching pool includes a pool body, an injection device for forming slag into fine particles and a conveying device for taking out fine particles from the pool body; The invention enables rapid cooling of molten slag and formation of fine molten slag particles through the arrangement of water quenching device, injection device and conveying device, which facilitates collection and subsequent treatment, and improves processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of fly ash melting equipment, and in particular relates to a novel processing equipment for melting fly ash. Background technique [0002] Fly ash is the tiny ash particles discharged from the combustion process of fuel (mainly coal), which belongs to hazardous waste, also known as fly ash or soot; The hot surface is formed by cooling after absorbing heat; due to the effect of surface tension, most of the fly ash is spherical, the surface is smooth, and the micropores are small; the chemical composition of the fly ash is related to the coal composition, coal particle size, boiler type, combustion conditions and The amount of fly ash is directly related to the ash content in coal combustion; according to the coal consumption in my country, about 250-300kg of fly ash is produced by burning 1 ton of coal; if a large amount of fly ash is not controlled or treated, it will Cause air pollution, enter the water will ...
