Description
Technical field
The present invention relates to a kind of water sealed tank, particularly relate to a kind of buoyancy module formula low pressure loss water sealed tank and using method thereof.
Background technique
Catalytic Cracking Technique of Heavy Oil is a large amount of technology that generally adopt in petrochemical refining's industry.By this technology, a large amount of heavy oil residues (accounting for the more than 60% of raw material) that petroleum refining time processing process produces can be converted into the light oil components such as the gasoline, diesel petrochemical gas of wilderness demand in national economy.Catalytic Cracking Technique of Heavy Oil is the important secondary operations means of oil refining industry.
In catalytic cracking unit, the energy-recuperation system using flue gas turbine expander as capital equipment, is occupying critical role aspect raising Business Economic Benefit; And flue gas water sealed tank is in whole smoke energy recovering system, ensure the visual plant of this security of system, long-term operation.The working principle of this system is: under certain process stage, high-temperature flue gas does work by flue gas turbine expander, and the power of generation directly drives main air compressor operating.The power that this flue gas turbine expander produces, portion even all replaces the motor of former driving main air compressors greatly, thereby greatly reduces the power consumption of catalytic cracking unit.But in order to ensure smoke energy recovering system long period, safety and steady operation, and normal Maintenance and Repair, must flue gas water sealed tank be set in the entrance and exit both sides of flue gas turbine expander.
The power that flue gas turbine expander produces is relevant with the pressure of outlet with flue gas flow and flue gas turbine inlet, and for the catalytic cracking unit of a set of sizing, exhaust gas volumn, flue gas turbine expander inlet pressure are constant.And outlet pressure (back pressure) is lower, the power of cigarette machine output is just more.By a set of 30x104t/a heavy oil catalytically cracking equipment, the exhaust gas volumn of having an appointment about 4000NM3/min, the experience obtaining according to execute-in-place and data, the every increase of cigarette machine inlet outlet pressure differential 1KPa, the power of flue gas turbine expander output can increase 120KW left and right, and economic benefit is very considerable.Therefore, reduce flue gas turbine expander outlet pressure, the monomer pressure drop that reduces flue gas turbine expander front and back equipment is the important means that improves flue gas turbine expander output power.
When traditional water sealed tank is normally worked, flue gas through flue from smoke inlet pipe 1, enter in the cylindrical shell 3 of water sealed tank, (as shown in Figure 1) due to flue gas in water sealed tank circulation path will through 180 ° and 90 ° turn for twice to, the circulation path of flue gas has experienced dilatation deceleration, 180 ° and 90 ° and has turned to processes such as, reducing acceleration, and while causing flue gas normally by water sealed tank, the pressure loss is larger.Generally along journey circulating resistance loss 2-4KPa.In view of above-mentioned factor, in order to improve the output power of flue gas turbine expander, improve device energy and reclaim ratio, develop New Low Voltage and fall flue gas water sealed tank and be very important.
