Feeding system of dangerous waste incinerator

Abstract

The invention relates to a feeding system of a dangerous waste incinerator. A main material pushing cylinder is installed on a support. A feeding port of the main material pushing cylinder is provided with a hopper for dangerous waste to enter. A material pushing oil cylinder is installed on the end face, located in the support, of the main material pushing cylinder. An opening used for a material pushing piston to push the dangerous waste out is formed in the end face, located outside the support, of the main material pushing cylinder, and a feeding flashboard is embedded in the lower end of the hopper. In the feeding system, both the feeding flashboard and a material conveying flashboard are in a closed state, flames and heat, generated from the main material pushing cylinder, due to combustion of the dangerous waste are isolated, leakage of waste gas is also avoided, and the material pushing piston in the main material pushing cylinder can generate ten-ton pushing force so as to push the dangerous waste into a combustion section from the opening in the end face of the outer side of the main material pushing cylinder; a maintaining oil cylinder can push the main material pushing cylinder to move towards the interior of the support, equipment maintaining can be conveniently conducted by maintaining personnel; and to sum up, the whole process can be conducted automatically or manually, the automation degree is high, the dangerous waste is conveniently conveyed, waste gas generated in combustion cannot leak, and the system works safely and reliably.

[0002] With the development of industry, the hazardous waste discharged from the industrial production process is increasing day by day, which brings serious pollution and potential impact on people's living environment. Inhalation, inhalation, contact, etc. poison people's health, and some may cause dangerous events such as combustion and explosion. At the same time, the pollution of air and soil will become a bottleneck restricting economic activities.

At present, the treatment methods for hazardous waste include physical treatment, chemical treatment, biological treatment, heat treatment, solidification treatment and other methods. The heat treatment refers to destroying and changing the composition and structure of solid waste through high temperature, while achieving volume reduction and harmlessness. Or for the purpose of comprehensive utilization, incineration in heat treatment can not only treat hazardous waste, but also reuse waste heat, which reduces the cost of treatment. The equipment used for incineration is a hazardous waste incinerator, and its main structure includes a feed section, a combustion section, Among them, the feeding methods commonly used at the feed end include direct dumping, screw feeding and push feeding. The first one is to transport hazardous waste into the material pipe through conveying tools such as belts, and the hazardous waste falls directly through the material pipe. into the combustion section, because the hazardous waste is easily stuck in the material pipe, resulting in poor feeding and affecting the incineration efficiency; the second is to push the hazardous waste into the combustion section through a rotary feeding structure such as an auger. In this method, the hazardous waste It is easy to cause problems such as adhesion due to various shapes, requires frequent maintenance, and cannot work stably for a long time; the third method is to use the piston in the oil cylinder to squeeze the hazardous waste and then introduce it into the combustion section, but this method is easy to form a material seal at the front end of the oil cylinder , once these material seals are ignited, it will seriously damage the structure such as the oil cylinder
