The invention discloses a liquid air refrigeration power generation device for a data center, and a working method. The liquid air working medium refrigeration power generation device for the data center comprises an ultralow-temperature liquid storage tank, a high-pressure and ultralow-temperature liquid pump, a high-pressure and ultralow-temperature pipeline, a jet flow drainage apparatus, a low-temperature heat exchanger, a low-temperature and high-pressure gas pipeline, a gas mixing drainage apparatus, a temperature-rising, pressure-increasing and entropy-compensating heat exchanger consisting of a gas expansion section, a medium-temperature heat exchanger and a gas contraction section, a normal-temperature working gas pipeline, a gas turbine input valve, a working gas path, a gas turbine, a generator, an exhaust gas path, a gas turbine output valve, a gas return pipeline, a refrigeration water return input pipeline, a low-and-medium-temperature heat exchanger connection pipeline, a refrigeration water return output pipeline, an after-gas discharging opening, a liquid gas injection opening, an overhaul short circuit pipeline, an overhaul short circuit gas valve and a drainage gas return pipeline. According to the liquid air refrigeration power generation device for the data center, the refrigeration unit purchase cost and the backup generator set purchase cost can be reduced; due to modes of reduction of the power consumption of a refrigeration unit in the data center, auto-using power generated by the low-temperature generator set and the like, the power consumption of the data center is greatly reduced.

The invention discloses a system and a method for avoiding low-temperature corrosion of an air preheater by using phase-change heat exchange, and belongs to the field of biomass energy utilization. The system and the method aim to solve the problems that boiler high-temperature and high-pressure water supply is used as a heat source to preheat air, the air preheater occupies large area and bears high temperature and high pressure, a water pump consumes a large amount of electricity, and the investment and running cost are high. A fume cooler is connected with steam separators arranged in a steam drum; the steam drum is connected with a steam-air heat exchanger; the steam-air heat exchanger and the steam drum are connected with a mixer; the mixer is connected with the fume cooler via a low-pressure circulation pump; the steam-air heat exchanger is connected with the air preheater. Saturated water and thermal fume exchange heat in the fume cooler to obtain a steam water mixture, the fume exhausting temperature is lowered, the steam water mixture is separated via the steam separators to obtain saturated steam and the saturated steam is used as a steam-air exchanger heat source to preheat the air, as a result, the inlet air temperature of the air preheater is raised, and the low-temperature corrosion of the air preheater is avoided. The system and the method are applied to biomass-fired boilers or coal-fired (higher sulphur content) boilers.

The invention relates to a non-hot processing method for zongzi leaves, which comprises the following steps of: soaking indocalamus leaves which sufficiently grow up, but are not provided with obvious wax layers in aqueous solution of sodium hydroxide so as to dewax, soften and clean the indocalamus leaves; taking out the indocalamus leaves, cleaning the indocalamus leaves, draining the indocalamus leaves and then pickling the indocalamus leaves in salt or aqueous solution of salt; and finally, taking out the indocalamus leaves, rinsing the indocalamus leaves in the aqueous solution of salt clean, then classifying the indocalamus leaves according to the standard of the zongzi leaves, respectively placing the indocalamus leaves into plastic bags for food packaging and carrying out vacuum sealing on the plastic bags. The method not only has no energy consumption caused by heating, but also has no water consumption caused by using the previous rehydration process, also has no food safetyhazard and is a processing method which is energy-saving, can be used for reducing the consumption and is convenient and safe.

The invention provides a fish passing system and method free of water resource losses and free water surfaces. The fish passing system is composed of a dam, a fish outlet tunnel, a fish inlet tunnel, a fish collection chamber, a fish outlet gate, a fish inlet gate, a downstream river channel, a sound making unit, a light-emitting unit, a power supply, a material injection machine, a material injection pipe, a fish exploration radar and a master control system. Compared with an existing fish way design method, the fish passing system has the remarkable differences that because the fish passing system is provided with fish passing tunnels and the fish collection chamber which have pressure and are free of free water surfaces, fish way establishment and maintenance expenses are remarkably reduced, project construction lands are greatly saved, almost no water resources are consumed by fish passing, and the fish passing efficiency is improved. A designed fish way can be used for temporary food discharge as well.
