Intelligent sludge incinerator

Abstract

The invention discloses an intelligent sludge incinerator. The sludge incinerator comprises an outer furnace body, an inner furnace body, a base, an electrically driven automatic slag discharge grate, a screw feeder, an automatic slag discharge device, a diesel oil burner, a primary air inlet system, a secondary air inlet system and a controller, wherein the controller is used for controlling one or more temperature sensors arranged at a hearth, a smoke outlet and a primary inlet, an oxygen quantity sensor arranged at the smoke outlet and a weight sensor for automatic slag discharge. The intelligent sludge incinerator can realize reduction and harmlessness of sludge by adopting a bubbling suspension combustion method, and meanwhile realizes low discharge of pollutants; the combustion is stable by automatic control of parameters of primary and secondary air inlet, and the temperature in the incinerator is controlled at 850 to 950 DEG C all the time for combustion; and the sludge incinerator has high automation degree, saves labor, relieves labor intensity, realizes stable incineration of the sludge, obviously reduces the fault rate, and has low maintenance expense and humanized operation.

Description

technical field [0001] The invention relates to a sludge incineration device, in particular to a device capable of treating low calorific value, flame retardant homogeneous particles and powdery substances through incineration; it is suitable for treating activated sludge produced by municipal sewage treatment plants and waste water treatment plants. Intelligent sludge incinerators for organic sludge, chemical sludge, paper sludge, etc. Background technique [0002] As we all know, in the process of industrial sewage, domestic sewage and municipal tap water treatment, sludge of various properties will be produced. There are relatively large differences in its composition and properties, and some of them are hazardous wastes. With the development of my country's environmental protection in recent years, sludge treatment has begun to start, but most of the local sewage treatment and associated products of industrial production - sludge has not been well disposed of, and a cons...

Problems solved by technology

Various equipment and devices have also been gradually added, and various harmless treatments have been carried out on the sludge, such as high-pressure reaction to petroleum cement, adding sewage sludge to power plant boilers for incineration, making sludge into bricks, and sludge Fertilizer making, etc., but the general practice cannot be completely harmless, especially by putting high-concentration pollutants such as sludge into low-concentration pollutants to dilute the discharge, resulting in implicit excessive discharge, rather than completely harmless , Sludge incineration is a disposal method that utilizes an incinerator to oxidize the organic matter in the sludge at high temperature to completely mineralize the sludge into a small amount of ash. The sludge treatment method with incineration technology as the core is the most thorough treatment method. The commonly used treatment method, incineration treatment of sludge has the advantages of small footprint, fast treatment, large volume, obvious weight reduction, heavy metals in the ash are not easy to leach, and can also be used as building materials or paving, etc. Domestically, it has begun to realize The advantages of incineration are being actively explored and applied in accordance with local conditions

[0004] However, the traditional sludge incinerators generally have the disadvantages of low degree of automation, low processing efficiency, difficult control of the temperature in the furnace, unstable sludge incineration, high failure rate, and high maintenance costs.
