Description

Environmental protection waste incinerator

technical field

The invention relates to an incinerator device, in particular to an environment-friendly garbage incinerator.

Background technique

At present, various incinerators continue to appear in our country, and the technology is constantly reforming and innovating. According to the "Boiler and Boiler Room Equipment" published by China Construction Industry Press in December 1990, and the "Biomass Fuel User's Manual" published by Beijing Chemical Industry Press, they respectively introduced various types of boilers in the country in recent years. According to the structure of the boiler and the use of the incinerator, these incinerators have achieved great results in improving the combustion value of fuel, improving thermal efficiency, and saving energy.

However, with the continuous development of science and technology today, the original incinerator structure, combustion method and environmental protection performance are far from meeting and adapting to the needs of today's society. The waste incinerators used today have complex structures and insufficient incineration, and the exhaust gas causes secondary pollution. In addition, the incinerators are prone to burn out due to the high temperature of the furnace, resulting in a short service life of the incinerator.

Contents of the invention

The object of the present invention is to provide an environmentally friendly garbage incinerator with ingenious structure and easy manufacture, which not only improves the environmental protection performance of the incinerator, but also prolongs the service life of the incinerator.

Technical scheme of the present invention is realized like this:

An environmentally friendly garbage incinerator, which includes a furnace body, a soot cleaning port, a furnace, a nozzle and a chimney. The furnace body is composed of an incinerator liner and a furnace shell. There is a garbage feeding port and a nozzle. The nozzle is provided with a secondary oxygen supply chamber. The nozzle is connected to the chimney through a flange. The top of the chimney is provided with a chimney cover. A furnace door is arranged at the lower part, an incinerator oxygen supply chamber is arranged inside the ash cleaning port, the incinerator oxygen supply chamber is connected with an air duct, and the secondary oxygen supply chamber is connected with a secondary oxygen supply pipe.

After removing the chimney, the nozzle can be connected to devices that require heat energy, such as a dryer, a heat exchanger, etc., and the heat emitted by the nozzle can be used to dry articles and make full use of the heat energy of the incinerator.

The inner tank of the incinerator is provided with refractory bricks or other refractory materials, for example, a layer of rare earth refractory mud. The rare earth refractory mud layer is made of rare earth oxide ore or rare earth nitrate, which can be lanthanide rare earth, such as cerium oxide or yttrium oxide; it is mixed with refractory mud and binder and applied to the interior of the incinerator liner. Rare earth oxide ore or Rare earth nitrate can improve the combustion efficiency as the co-catalyst, stabilizer, dispersant and promotor of the combustion catalyst; the refractory brick or other refractory materials of the present invention can prevent the inner tank of the incinerator from being burned out because the furnace temperature is too high, prolonging the the life of the incinerator.

The air pipe and the secondary oxygen supply pipe can be connected to a blower, in order to provide more sufficient oxygen for the incinerator, which is more conducive to the combustion of garbage and reduces the emission of dense smoke.

The garbage feeding port is provided with a garbage sand and gravel diversion box and a smoke shield, the entrance of the garbage gravel diversion box is provided with a sand and gravel filter, the sand and gravel filter is provided with a gravel box, and the sand and gravel box is provided with a gravel cleaning port The purpose is to filter out the mud and sand in the environmental waste from the incinerator, so as to prevent the mud and sand from accumulating and blocking the grate, thereby affecting the use of the incinerator.

The beneficial effects of the environment-friendly garbage incinerator of the present invention:

1. Refractory materials are used as the inner liner of the environmental protection waste incinerator. The refractory bricks installed in the inner liner of the environmental protection waste incinerator can not only make full use of the heat emitted by the furnace of the environmental protection waste incinerator to preheat it, but also avoid the risk of burning due to excessive furnace temperature. The phenomenon of burning out the furnace of the incinerator prolongs the life of the incinerator.

2. A secondary oxygen supply chamber is added at the junction of the nozzle and the chimney to increase the amount of oxygen in the nozzle, thereby improving the degree of garbage vaporization of the incinerator, reducing secondary pollution caused by exhaust emissions, and saving energy and environmental protection.

3. Rare earth refractory mud layer Adding rare earth oxide ore or rare earth nitrate to the refractory mud can be used as a co-catalyst, stabilizer, dispersant and accelerator of the combustion catalyst, which can improve the combustion efficiency.

4. When the garbage is added to the incinerator, the mud and sand in the environmentally friendly garbage are filtered out of the incinerator through the garbage sand and gravel diversion box to prevent the mud and sand from accumulating to block the grate and affect the use of the incinerator.
