InactiveCN108795508AImprove utilization efficiency and energy utilizationReduce emptyingChemical industryGaseous fuelsLiquid hydrogenLiquefied natural gas
The invention relates to an expansion refrigeration method for separating coke oven gas by using nitrogen and helium. The method comprises the following steps: (1) after compression and precooling ofcoke oven gas, feeding the treated coke oven gas into a first-stage nitrogen cycle expansion refrigeration system, and feeding the treated coke oven gas into a rectification tower through further cooling; (2) after methane exhausted at the bottom of the rectification tower is cooled and liquefied through a second-stage nitrogen cycle expansion refrigeration system, feeding the cooled and liquefiedmethane into a natural gas storage tank for storage, after carrying out first ortho para conversion and second ortho para conversion on hydrogen exhausted at the top of the rectification tower in sequence, feeding the hydrogen into a liquid hydrogen storage tank for storage, wherein cooling capacity is provided by the second-stage nitrogen cycle expansion refrigeration system in the first ortho para conversion process, and cooling capacity is provided by a third-stage nitrogen cycle expansion refrigeration system in the second ortho para conversion process. Compared with the prior art, liquefied natural gas and liquid hydrogen are prepared from the coke oven gas through nitrogen and helium expansion low-temperature cycle, so that the utilization efficiency and energy utilization rate of the coke oven gas are improved, the evacuation phenomenon of the coke oven gas is reduced, and the environmental pollution is little.

Boiler bottom structure of submerged scraper conveyor in thermal power plant

The invention discloses a boiler bottom structure of a submerged scraper conveyor in a thermal power plant. A transitional slag pit and a boiler bottom deslagging device are arranged between a boiler and the submerged scraper conveyor, and a boiler bottom is sealed between the boiler and the transitional slag pit through a mechanical sealing device. The boiler bottom deslagging device comprises hydraulic shutoff doors which all horizontally move during opening or closing. The mechanical sealing device absorbs expansion displacement of the boiler and seals the boiler bottom at the same time, the problems that the water level of a water seal tank cannot be controlled easily and periodical cleaning is needed are solved, and the hydraulic shutoff doors can be flexibly opened and closed, can serve as isolation doors and can effectively achieve pre-cooling and pre-crushing of large slag blocks. A system is safe and reliable, operation is easy, running is convenient, and the functions of large slag pre-crushing and temporary storage, non-stop overhaul of the submerged scraper conveyor and slag water ultralimit high-temperature protection of the submerged scraper conveyor are achieved.

Bidirectional environment-friendly energy saving boiler with three return strokes

The invention relates to a bidirectional environment-friendly energy saving boiler with three return strokes, which comprises a boiler body, an inner water jacket and an outer water jacket, wherein a heat collecting plate and a heat collecting tube are extended at the upper part of the inner water jacket; a heat collecting tube is additionally installed in a bent flue; and a dust falling chamber and a dust removing door are arranged at the lower part of a flame outlet. In the invention, combustion chambers of the bidirectional environment-friendly energy saving boiler with three return strokes comprise a reverse combustion chamber and a secondary combustion chamber, and a double-layer water tube grate is arranged below the reverse combustion chamber, thereby having larger heat absorption capacity and fastest heat energy transmission. The invention has the advantages that the flue with three return strokes is used, thus the flue is lengthened in the boiler body so as to be convenient for heating the heat collecting plate and the heat collecting tube; and in addition, the flame in the reverse combustion chamber goes downwards from the gap of the first layer of the double-layer water tube grate, and the tongue of flame directly goes to the second layer of the water tube grate, so the boiler has high heating speed and more heat utilization, saves coal by more than 45%, and can burn industrial and household garbage. The boiler of the invention can be widely applied to large factories and mines, organizations, districts and hotels for heating and bathing. Thus, the boiler of the invention is ideal equipment for meeting the current national requirements of energy saving and emission reduction.
