Abstract
The utility model discloses a steam drive structure of large-scale natural gas-chemical fertilizer devices. A large-scale turbine unit is connected with a compressor driven by steam; a high-pressure steam connection pipe and a steam exhaust connection pipe are connected on the large-scale turbine unit; an air inlet pipe and a high-pressure air outlet pipe are connected on the compressor driven by steam; and the air outlet pipe of the compressor driven by power is connected with the high-pressure air outlet pipe. The steam drive structure can maximally reduce the fuel for the fast gas pans through replacing the power steam gas with electric energy, and can adopt the saved fuel gas as raw material to use; and load-reducing operation of the fast pans and the low-load operation of auxiliary pans can be realized without any adjustment of the high-pressure steam system. After the applicant makes the statistics, the fuel gas can be saved for 20930400 Nm<3> each year if the large-scale turbine unit of which the power is 35-40 t/h is driven by electric energy, namely, the production volume of the urea is increased by 34698.94 tons, so that the steam drive structure disclosed by the utility model has good economic benefits.
Description
Technical field
The utility model relates to a kind of steam driven structure of large-scale natural gas chemical fertilizer plant, belongs to the equipment technical field of utilizing the gas production chemical fertilizer.
Background technique
The enterprise that large-scale natural gas is produced chemical fertilizer receives the restriction that rock gas supplies quantity not sufficient in recent years; Output is affected greatly; On the other hand, along with the merger gradually of national market for natural gas price mechanism, be that the production of chemical fertilizer enterprise of raw material faces increasingly high cost pressure with the rock gas.For alleviating this situation, the rock gas fertilizer enterprises must propose effective solution.
Analyze present case, existing large-scale natural gas chemical fertilizer plant rock gas is both as raw material uses that also act as a fuel, and like the rock gas packaged boiler of use in producing, the steam of its generation is used to regulate, the vapour system of the whole device of balance; Wherein act as a fuel with rock gas; As power steam demand maximum is kinetic energy to vapour compression machine to be provided by large-scale turbine unit; Its structural drawing is as shown in Figure 2, and the steam consumption that therefore reduces large-scale turbine unit can reduce the use amount of rock gas as combustion gas.
Summary of the invention
The technical problem that the utility model will solve is, a kind of steam driven structure of the large-scale natural gas chemical fertilizer plant that gas uses that utilizes electric energy to replace rock gas to act as a fuel that increases fertilizer production, increases economic efficiency is provided, and can overcome the deficiency of existing technology.
The technological scheme of the utility model; It comprises large-scale turbine unit; Steam driven compressor; Large-scale turbine unit is connected with steam driven compressor; On large-scale turbine unit, be connected with high pressure steam connecting tube and steam exhaust steam connecting tube, on steam driven compressor, be connected with air intlet and high-pressure air outer pipe, the compressor steam outlet pipe of electric drive compression system is connected with the high-pressure air outer pipe.
The quantity of electric drive compression system is more than 1 or one.
Compare with existing technology; The utility model substitutes the natural gas power steam through electric energy, can farthest reduce the rock gas packaged boiler and use fuel, and the fuel natural gas of saving is used for using as raw material; And high pressure steam system is not done any adjustment; Can realize pressure cooker Reduction of Students' Study Load lotus and the underrun of auxilliary pot, so both improve economic benefit, production capacity is improved relatively.Through claimant's statistics, drive the large-scale turbine unit that replaces power 35-40t/h, about 20930400 Nm of annual replaceable fuel natural gas with electric energy
3, amount to 34698.94 tons in year raising the output urea, have good economic benefit.
