Problems solved by technology

[0007] 70% of them are treated by industrialized incineration. Therefore, the research on its technology has also started earlier, and the flue gas treatment technology after incineration is relatively mature and reliable. Most also have the so-called white smoke phenomenon
However, due to the high energy consumption of the traditional incineration process, it is easy to produce secondary pollution, which makes many places discouraged from incinerating animal carcasses. In some places, it is difficult to pass the environmental impact assessment of the project because of the strong demand of the surrounding residents not to install chimneys. cause great difficulty

Embodiment 1

[0049] see Figure 1 to Figure 4 , the flue gas purification process of a kind of animal harmless incineration treatment of the present invention is characterized in that, comprises the following processing steps:

[0050] (1) Animal carcass incineration: Animal carcasses are placed in an incinerator with a temperature above 1000°C, after 30 minutes of incineration, the ash after incineration is collected and processed;

[0051] (2) Filtration: The flue gas produced after incineration is filtered through the honeycomb mesh filter layer in the smoke elimination chamber, and the dust particles and water vapor with a particle size of more than 1 mm in the flue gas are initially removed, and the flue gas flows through the smoke elimination chamber. The speed is 2 meters per second, the flow time is more than ten seconds, and an appropriate amount of oxygen is supplemented through the smoke elimination pipe to fully burn the organic matter produced by incomplete combustion in the f...

Embodiment 2

[0080] see figure 1 , a kind of equipment used in the flue gas purification process, characterized in that it includes:

[0081] An incinerator, the incinerator is provided with a slag outlet and a flue gas outlet; in this example, the flue gas outlet of the incinerator is provided with a first temperature sensor;

[0082] In the smoke elimination chamber, a honeycomb mesh filter layer is arranged in the shell, and the honeycomb mesh filter layer adopts a honeycomb mesh structure made of high-temperature-resistant ceramic materials, and the honeycomb mesh structure is filled with high-temperature-resistant metal alumina fiber filaments , the housing is provided with an inlet and an outlet, and the inlet adopts a pipeline to connect the flue gas outlet of the incinerator; the honeycomb mesh structure in the present invention can increase the smoke elimination area and improve the smoke elimination efficiency; the smoke elimination chamber in this example The outlet is provided...

Abstract

The invention relates to the technical field of animal harmless treatment, in particular to a flue gas purifying technique and device for animal harmless incineration treatment. The flue gas purifyingtechnique is characterized by comprising the following treatment steps that animal carcasses are incinerated for 25 minutes or above at the temperature of 1000 DEG C or above; flue gas generated after incineration is filtered through a cellular-network-shaped filter layer in a flue abatement chamber so as to remove dust particles with the particle size being one millimeter or above and moisture;the flue gas enters a temperature-regulating device to be subjected to temperature regulating to 850-1000 DEG C; quenching is conducted to 160-170 DEG C; activated carbon or slaked lime is sprayed soas to preliminarily remove acidic substances in the flue gas; the flue gas enters a bag-type dust remover to be further subjected to dust removing; the flue gas enters a spraying-type serpentine tube,spraying liquid at the temperature of 5 DEG C is adopted to spray the flue gas, and thus gas-liquid fusion separation is achieved; and the flue gas is adsorbed by an activated carbon composite and then exhausted into the atmosphere. Compared with the prior art, the flue gas purifying technique and device for animal harmless incineration treatment adopts the flue gas and liquid fusion technology initiated at home and abroad, an activated carbon composite adsorption layer is adopted, thus the dust-free, low pollution and chimney-free effects are achieved, environment-friendly and economic effects are achieved, and the flue gas purifying technique and device are going to be the industry standard.

Description

technical field [0001] The invention relates to the technical field of animal harmless treatment, in particular to a flue gas purification process and equipment for animal harmless incineration treatment. Background technique [0002] The flue gas produced in animal incineration treatment, the research status and level at home and abroad and the necessity of solving key problems: [0003] (1) Research status and level at home and abroad [0004] Shanghai is the first province and city in China to establish a harmless centralized treatment site for sick and dead animals. In 2002, it began to build a treatment line with incineration technology as the main equipment. At the beginning, because there was no ready-made process technology in China to refer to, it was basically based on the process construction of domestic waste incineration. The difficulty of air purification treatment is relatively large. With the continuous increase of the treatment capacity, the Shanghai Anima...
