The invention provides a combustion supporting device processing nitrous gas. The combustion supporting device processing nitrous gas comprises a shell. A column body is axially arranged at the centerof the shell. An ignition device is disposed at the bottom of the column body. The inner portion of the shell is divided by partition plates into a central ventilation channel, an inner cyclone air channel, a mixed air channel and an outer cyclone air channel from inside to outside. A bottom outlet of the outer cyclone air channel is provided with an outer cyclone nozzle, and the outer cyclone nozzle deviates outward and forms a certain angle with the axial direction of the combustion supporting device. Rotating wind blades are disposed at the bottom outlet of the central ventilation channel.When inner air, outer air and mixed air are sprayed out and leave the combustion supporting device, a high-speed rotating airflow is formed, so that mixed gas with the reducibility and the air with the oxidizing performance can quickly react and are burned rapidly. When N2O leaves the combustion supporting device, the N2O is completely wrapped in the middle of the combustion flame, the advantageof completely no escape is achieved, and after diffusion, the N2O enters the flame to assist combustion and participate in decomposition combustion.

The invention discloses an urban domestic sludge treatment process.The process includes the following steps of 1 preparation of dewatered sludge, wherein sludge which is concentrated and dewatered by an urban sewage treatment plant is adopted; 2, conditioning of sludge, the dewatered sludge is conveyed to a slurry regulating pool, a chemical conditioning agent is added, and the mixture is stirred and mixed to be uniform through a stirrer in the regulating pool; 3, slurry radiation treatment, wherein slurry obtained after chemical conditioning is conveyed to a radiation workshop through a conveyor belt for radiation treatment; 4, slurry low-temperature pyrohydrolysis; slurry obtained after radiation treatment is beaten into a reaction kettle through a slurry conveying pump, a reaction kettle keeps closed in the work period, after slurry enters the reaction kettle, the temperature is raised continuously in the continuous stirring process, when the temperature is raised to 85-95 DEG C, timing is started, and the temperature is maintained at 90 + / -5 DEG C for 30-35 minutes; 5, slurry obtained after low-temperature pyrohydrolysis can be directly dewatered through a membrane filter press, the moisture content is lowered to 60% or below, the number of fecal coliform groups is smaller than or equal to 100 / g (mL), the slurry obtained after low-temperature pyrohydrolysis can also be combined with anaerobic digestion which has been developed and matured for stabilizing treatment, and methane gas utilization is achieved.

The invention discloses a self-propagating high-temperature synthesis system capable of solidifying radioactively polluted sand, which includes a glove box, a laser generator, a sealed container, a paperless recorder and an exhaust gas treatment part. The outer wall of the glove box is provided with an aviation plug. The outer wall of the glove box is provided with an air inlet and a booster port, and the inlet ends of the air inlet and the booster port are respectively connected with a nitrogen cylinder through a pipeline, and the gas outlet of the glove box is connected with the exhaust gas through a pipeline. The processing part is sealed and connected, the top of the glove box is sealed with quartz glass, and the sealed container is located in the glove box. The patent of the present invention uses a specially customized glove box to isolate radioactive sand and protect experimental operators; The generator ignites the self-propagating material in the sealed container, which can realize non-contact ignition and reduce disturbance to polluted sand.

The invention relates to a die for pressing hazardous waste to be a high-density module in an ultrahigh-pressure hydraulic mode. The die is composed of an upper pressure-bearing module (1), an upper die puncher pin (2), a middle module (3), a lower pressure-bearing base (4), a sliding block (5), a large hexagonal screw (6) and a small hexagonal screw (7). The upper pressure-bearing module (1) connected with a hydraulic machine is fixedly connected with the upper die puncher pin (2) through the small hexagonal screw (7). The center of the middle module (3) is provided with a vertical-through die cavity matched with the upper die puncher pin (2). The middle module (3) is fixedly connected with the lower pressure-bearing base (4) through the large hexagonal screw (6). The lower pressure-bearing base (4) is provided with a slot, and the slot corresponds to the die cavity and horizontally penetrates through the lower pressure-bearing base (4). A sliding block (5) which moves horizontally is arranged in the slot. The die can ensure that pressed material density meets requirements and facilitate die removal, can avoid corner breakage, and can be widely used for processing solid hazardous waste such as fly ash, slag and waste catalysts.

The invention discloses an intake method of a garbage incineration boiler hearth and garbage incineration boiler equipment thereof, and belongs to the technical field of garbage incineration boiler operation methods and equipment thereof. The intake method comprises the following steps: a) a primary intake temperature of an air chamber is reduced; and b) the position of an intake pipe on a secondary intake furnace wall is raised. The garbage incineration boiler equipment comprises an air preheating device, a direct connecting pipe, an electric circular air door and a DCS distributed control system; the air preheating device includes a preheating pipe, an air inlet and an air outlet; the direct connecting pipe includes multiple sections of straight pipes and multiple 90-degree shrimp elbows; one end of the direct connecting pipe is connected with a primary intake port of the air preheating device, and the other end is directly communicated with an air chamber intake port below the hearth; the electric circular air door is arranged on one section of straight pipe; the DCS distributed control system can be disconnected or electrically connected with the electric circular air door; and three sets of furnace wall intake pipes are respectively arranged on the front and back walls of the upper and middle parts of the hearth. The Intake method of the garbage incineration boiler hearth and the garbage incineration boiler equipment thereof have the following beneficial effects: the furnace slag caking phenomenon and the furnace slag blockage cannot be generated; and the outlet temperature of the hearth is high, so that the combustion is sufficient.

A back mixing method in the biological pretreatment of sludge comprises the steps: a) the dry sludge plastotype with the water ratio being 35 percent to 37 percent is processed into cylindrical granular dry sludge A and striping dry sludge B, which are dried until the water ratio reduces to 20-25 percent; b) the dry sludge A and B prepared in step a are mixed as per the mass ratio of 8-10:1 to bemade into back mixing dry sludge; c) the back mixing dry sludge is mixed with wet sludge and accounts for 25-35 percent of the mass of the total materials, and the turn and throw are carried out for 3-7 times per week, with ventilation and oxygen supply, the temperature is maintained between 45-60 DEG C, when the water ratio reaches 35 percent to 37 percent, fertilizer manufacture and incineration and other subsequent disposals are conducted. Through the back mixing of the dry sludge A and B of different shapes, the invention can reach the aims of improving the space structure of sludge and shortening the pretreatment period; and the final pretreatment product dry sludge is of granular structure, which is more beneficial to the execution of further disposals such as fertilizer manufactureand incineration.
