The invention discloses a biocarbon / steam co-production device and technology through biomass pyrolysis, gasification, and combustion sectional conversion. The co-production device comprises a fluidized-bed pyrolysis and gasification furnace, a low thermal value gas combustion chamber, a primary separation device, a secondary cyclone separator, an air preheater, a steam generator, and a flue gas processing facility. The technology comprises the following steps: making biomass raw materials carry out pyrolysis and gasification reactions in the fluidized-bed pyrolysis and gasification furnace so as to generate biocarbon and high-temperature low thermal value fuel gas, separating the biocarbon and fuel gas by the two grade separation devices to obtain high quality biocarbon, transferring the separated high temperature fuel gas into the low thermal value gas combustion chamber, burning, and transferring the high temperature flue gas generated by the combustion into the steam generator to generate steam. The provided technology is advanced, the production equipment is simple and reliable, the production cost can be effectively reduced, and the production benefit is improved.

The invention provides complete processing equipment of coal gas expanded perlite, comprising a coal gas device, a preheating furnace, an expansion furnace, a cyclone dust collector, a material bin, a high-temperature induced-draft fan, a high-temperature discharging pipe and a high-temperature induced-draft pipe, wherein the preheating furnace is provided with a high-temperature hot-air inlet; one end of the high-temperature discharging pipe is communicated with a discharging port of the expansion furnace, and the other end of the high-temperature discharging pipe is communicated with a feeding port of the cyclone dust collector; one end of the high-temperature induced-draft pipe is communicated with the top part of the cyclone dust collector, and the other end of the high-temperature induced-draft pipe is communicated with an air inlet of the high-temperature induced-draft fan; and an air outlet of the high-temperature induced-draft fan is communicated with the high-temperature hot air inlet. The complete processing equipment has the advantages that high-temperature hot air in the cyclone dust collector is introduced to the preheating furnace for preheating ore sand by the high-temperature induced-draft fan, so that not only is the burning amount of coal gas in the preheating furnace reduced, but also the problem that the energy is wasted for nothing is solved.

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 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.

The cover is disposed so as to cover at least the opening of the upper surface of the refractory container made of refractory on the inner surface side through a gap, and when the inside of the refractory container is heated by a burner installed to penetrate the cover, The burner is provided with a continuous combustion control mechanism that adjusts the amount of combustion while continuously burning fuel with the burner, and an on / off combustion control mechanism that adjusts the switching time of burning and stopping of fuel by the burner and the amount of combustion. A switching device for switching combustion of the burner between said continuous combustion control mechanism and said on / off combustion control mechanism.
