Abstract
The invention provides a waste cutting preheating incineration steam dust removal and denitration integrated heat energy recycling process. Comprises the following steps: mechanical intelligent linear cutting garbage plastic bag wrapping and roller sorting garbage plastic recycling device. The recovered combustible garbage is preheated and dried in the furnace body and then is incinerated. The heat generated by burning the garbage is utilized to convert water and ammonia liquid into gaseous ammonia and water vapor in a heating mode. Under the condition of no catalyst, gaseous ammonia and steam are utilized to generate nitrogen oxide and sulfur dioxide by burning garbage, and the whole process is tracked and captured from the burning to the ending. The water vapor is converted into water body and water body wrapped with smoke particles through a cooling measure, so that the smoke particles are purified and dedusted indiscriminately. Filtering water body particles, and performing concentrated solidification treatment on waste residues; in the water body, the ammonia sulfite is oxidized into ammonium sulfate crystals as a byproduct. By utilizing the incineration heat energy, a device for pressing garbage plastics into brick and tile building materials and a device for converting the garbage plastics into heavy oil are arranged.

The technical scheme adopted by the garbage cutting preheating incineration steam dedusting and desulfurization and denitration integrated heat energy recycling process comprises the following steps of (2) garbage preheating drying incineration flue gas steam purification gas phase denitration and desulfurization integrated heat energy recycling device:
in order to reuse the heat energy of the garbage combustible. Especially, the high-temperature incineration of the garbage combustible materials with high water content is completed, the multilayer hanging frame is arranged above the furnace body, the garbage combustible materials with high water content are placed in the hanging frame, and the garbage combustible materials in the hanging frame are quickly evaporated by utilizing the heat generated by the incineration of the garbage, so that the combustible materials are preheated at high temperature. After the garbage combustible in the hanging frame is preheated and dried, the garbage combustible is thrown into a combustion area of the furnace body to be incinerated. The arrangement of the hanging frame solves the problem of high water content of the garbage combustible. Especially, the hanging frame is arranged at the lowest layer and is closest to flame, when the garbage combustible in the hanging frame at the lowest layer is subjected to high temperature and is about to reach the combustion degree, a power supply signal is input into the automatic unloading device of the hanging frame, the rope for controlling the turnover connecting rod is put down, the garbage combustible in the hanging frame automatically falls onto the U-shaped fire grate under the action of self gravity, and when the garbage plastic is put onto the U-shaped fire grate, the garbage plastic can be immediately combusted. And an overturning connecting rod arranged outside the furnace body on the hanging frame shaft plays a role in lever control. The garbage combustible is mainly plastic. The combustion of plastics is divided into two stages, namely a volatilization stage at about 200 ℃, the combustion is mainly completed by a delinking depolymerization reaction to release a large amount of heat, and the weight loss rate reaches 99% when the combustion is about 500 ℃. The hydrocarbons do not fix carbon. Only volatile components, a combustion stage and a burnout stage. Therefore, when the plastic is completely burned, the heat source is immediately lost, and the high temperature capability is difficult to form. In order to solve the problem of sustainable combustion of garbage combustible and increase the temperature accumulation capacity. The bottom of the incinerator is provided with a U-shaped fire grate as a combined body. On one hand, the U-shaped grate increases the incineration ventilation area; the ventilation area is increased by more than 50 percent compared with the plane grate. On the other hand, the U-shaped grate structure enables the garbage combustibles to be mutually gathered. The flames can mutually form radiation to generate high temperature to form accumulated temperature. The U-shaped grate structure makes up the problem that the garbage combustible does not have fixed carbon. The U-shaped grate structure provides conditions for continuous combustion of garbage combustible materials. The U-shaped furnace has large exhaust air volume, and provides guarantee for providing oxygen-enriched combustion of the garbage combustible. When the garbage plastic is burnt under the oxygen-rich condition, the generation of dioxin can be reduced firstly. Secondly, the gas components of the garbage putrefactive organic matters can be decomposed at high temperature. When the garbage combustible is burnt under the conditions of high temperature and oxygen enrichment, the generation of sulfur dioxide can be effectively reduced. When the temperature of the flue gas outlet reaches above 850 ℃, dioxin is prevented from being synthesized in the later combustion stage. In order to control the temperature condition of the furnace body, temperature monitors are arranged at different positions in the furnace body to provide data for controlling the waste incineration. Due to the combustible materials of the garbage, the garbage is combusted under the condition of oxygen enrichment. Therefore, the nitrogen oxide component in the smoke is greatly increased. In order to solve the problem, a selective catalytic reduction method is adopted for denitration and desulfurization of flue gas under the condition of not using a catalyst. Reducing agent: ammonia, urea. The advantages are that: no secondary pollution, and is nontoxic and pollution-free nitrogen and water. The sulfur dioxide in the flue gas can be removed by an ammonia method. In the prior art, ammonia method is used for denitration, and ammonia water liquid is atomized and mixed with flue gas after a high temperature window of 850 ℃ to 1200 ℃ is selected. By adopting the denitration method, the effect of reducing the nitrogen oxide by 50 to 60 percent can be achieved. In order to solve the problem that the prior denitration method is low in efficiency: the first method is to convert liquid ammonia into gaseous ammonia and water vapor by heating liquid reducing agent (ammonia water, urea liquid) with a heater. Secondly, a two-stage denitration measure is adopted for the waste incineration by utilizing gaseous ammonia and water vapor. The reducing agent heater is arranged in the high-temperature gas channel and is of a pipe arrangement structure. In order to prevent the waste from burning to generate excessive nitrogen oxides and sulfur dioxide from the source. The first section of ammonia method adopts the method that a reducing agent (gaseous ammonia and steam) outlet is arranged at the lower bottom of a U-shaped furnace exhaust, the gaseous ammonia and the steam enter a garbage combustion area, and the gaseous ammonia reducing agent, the steam and the garbage are burnt synchronously. When the gaseous ammonia reducing agent and the waste incineration are carried out synchronously, the reducing agent is enabled to capture the generation of the nitrogen oxides synchronously from the waste incineration source. Reducing agent and steam are added into the garbage for burning in the first time. When a large amount of water vapor and ammonia gas enter the garbage plastic combustion area, the generation conditions of nitrogen oxides and sulfur dioxide are fundamentally restrained. The ammonia steam and the water vapor enter a garbage combustion high-temperature area together, so that the gas-phase ammonia and the nitrogen oxide form a rapid reaction under the high-temperature condition of the reducing agent, and the utilization efficiency of the ammonia (urea) is improved. In order to solve the problem that the proportion of nitrogen oxide in flue gas is high (70 to 80 percent) in the oxygen-enriched incineration of garbage. In order to better improve the denitration efficiency of the ammonia process, a two-stage denitration method measure is adopted. And a second reducing agent outlet is arranged at the position of the high-temperature gas outlet of the incinerator. The flue gas outlet end of the incinerator is also provided with a gaseous ammonia reducing agent outlet. When the flue gas in the furnace body is concentrated at the flue gas outlet, the gaseous ammonia is utilized to form reduction reaction with the nitrogen oxide in the flue gas again. After the flue gas is subjected to secondary denitration, the denitration efficiency of the flue gas is greatly improved, and the nitrogen oxides in the flue gas are basically reduced. By utilizing the measures of gaseous ammonia (urea) two-stage denitration, the problem of low liquid-phase denitration efficiency of the ammonia process is effectively solved, and the ammonia process denitration achieves the best effect. The method for reducing nitrogen oxides by using an ammonia method provides favorable and convenient conditions for steam dust removal. In the process of burning the garbage, the reducing agent and the water vapor are added, which plays a key role in preventing the generation of dioxin. Especially, the reducing agent outlet is arranged at the position of the flue gas outlet of the incinerator, so that the secondary synthesis of dioxin is effectively prevented. The denitration and desulfurization liquid chamber and the steam water tank are arranged above the high-temperature gas channel. The denitration and desulfurization liquid (ammonia water and urea) tank and the steam water tank enable the ammonia water liquid (urea liquid) to automatically enter the heater to generate gaseous ammonia and water vapor through the control valve under the condition of no external force. The proportion of amine (urea) and water is according to the data fed back by nitrogen oxide monitor set at the back end of flue gas pipeline. The water vapor heater arranged in the high-temperature gas channel makes full use of the heat of burning garbage, removes dust by using water vapor, enables smoke particles and achieves the purpose of undifferentiated purification. In order not to influence the denitration and desulfurization by the ammonia process, the steam outlet is arranged at the rear end of the high-temperature gas channel, and in order to fully mix the steam and the flue gas, the fan is arranged at the steam outlet and automatically rotates under the driving of the flue gas, so that the flue gas and the steam are mixed. In order to perfect the furnace body in the initial stage of burning, the flue gas is purified. The reducing agent heater and the water vapor heater are provided with temporary heating devices to finish the tasks of dust removal, denitration and desulfurization of flue gas generated by combustion at the initial stage of the furnace body.

Namely, the phenomenon that the liquid is easy to accumulate when the temperature is low during combustion of the garbage plastic is prevented. But also solves the problem of ventilation required by the garbage plastics during combustion. The U-shaped fire grate can promote garbage plastics and combustible materials to complete the combustion task under the condition of oxygen enrichment, and lays a foundation for the reutilization of heat energy. 7. The arrangement structure of the U-shaped fire grate can gather loose garbage plastics, generate flames which radiate each other, and provide conditions for sustainable combustion of the plastics. The U-shaped grate structure makes up the problem of sustainable combustion of plastic under the condition that garbage plastic and combustible materials do not have fixed carbon and cannot form a stable heat source. The U-shaped grate ensures that the garbage combustible is always in a high-temperature state to complete the incineration task, and plays a key role in preventing the generation of dioxin. 8.
