The invention discloses a technique for producing synthetic ammonia gas by inputting nitrogen-rich air into a two-stage converter in a membrane method, and is characterized in that a portion of air enters a membrane separator after the air is compressed. The nitrogen-rich air obtained at the permeation residue side of the membrane separator can be directly mixed with outlet air of an air compressor so as to be used as plant air which enters the two-stage converter after being heated by high-temperature flue gas through an air pre-heater. The nitrogen-rich concentration in the plant air and theheat load of the air pre-heater are regulated so as to ensure appropriate H / N ratio and high methane conversion rate in the two-stage converter. The nitrogen-rich air obtained at the permeation residue side of the membrane separator is added into a one-stage converter to assist combustion so that the fuel utilization rate of natural gas is increased. The technique reduces the burning capacity ofhydrogen in the two-stage converter and increases the material utilization rate of natural gas by pre-heating the plant air to a higher temperature in the air pre-heater.

The invention discloses a method of producing biogas through Chinese medicine residues, relating to application of Chinese medicine residues and belonging to the field of utilization of biomass energy sources. The method is characterized by comprising the following steps of: crushing the Chinese medicine residues to 40 meshes, filling methane bacteria accounting for 10% of total amount of the Chinese medicine residues, adjusting the carbon-nitrogen ratio to be (20-25):1, and treating at 53-55 DEG C for 10 days; and performing an anaerobic digestion reaction to prepare biogas. The method has the beneficial effects that biogas preparation and combustion equipment is simple, the equipment is conveniently used and managed, rely of urban residents on fossil energy and emission of greenhouse gases are reduced, and the biogas contains no such poisonous gases as CO, thereby being more beneficial to human body health and excellent in environmental effect; the straw combustion quantity is reduced to create conditions for straw application and realizing sustainable utilization of rural lands; and the biogas is used for replacing the straws to greatly improve the living environment of farmers and improving the living standard of the farmers, thereby having excellent social benefit and ecological benefit.

The invention discloses a suffocating flame-retardant garbage can, which comprises a garbage can with a cylindrical structure, a switch door is installed on the outer wall of the garbage can, and the upper edge of the garbage can takes its own central axis as the center of the circle, etc. The corners are fixedly connected with three connecting plates, and the upper end surfaces of the three connecting plates are jointly fixedly connected with a top cover. The advantage is that: under normal conditions, the magnetic attraction between the permanent magnet and the ferromagnet is used to store the suffocation plate into the storage tank. In the fire extinguishing state, the heat is conducted to the ferromagnet through the heat conducting ring plate and the heat conducting block, and the internal temperature of the ferromagnet gradually rises Until it reaches the Curie temperature and turns into paramagnetism, the permanent magnet will no longer generate magnetic attraction to the ferromagnet, and the suffocation plate will move vertically downward under the action of its own gravity until it reaches the steps, forming a sealed space and isolating the outside air to complete the fire extinguishing , reduce the amount of combustibles burned and the harmful gases generated by the combustion, and protect the health of pedestrians.
