Abstract
The invention relates to an acetylene-producing device and an application method thereof.The acetylene-producing device comprises two acetylene devices, wherein pyrolysis apparatuses (1 and 1') in the two acetylene devices are communicated with one shared gas holder (2), and the gas holder (2) is communicated with compression apparatuses (3 and 3') in the two acetylene devices through connection pipelines.The acetylene-producing device realizes the interacting operation of the two acetylene devices, reduces the arrangement of one gas holder and saves the cost, thereby saving the configuration of construction period, related land and other resources. The application method meets the requirement for the load adjusting and balancing action of the two acetylene devices, thereby avoiding the damage to the apparatuses due to vacuum production in the gas holder and other devices as a result of the shutdown of certain apparatuses or the improper control on the gas flow, the rise of cracking gas manifold and acetylene furnace system pressure due to the explosion of the gas holder as a result of the overbalanced gas transportation or other problems.
Description
Technical field
The present invention relates to the production of acetylene, particularly relate to a kind of device for the production of acetylene and using method thereof.
Background technology
Industrial usually with Sweet natural gas and oxygen for raw material, adopt partial oxidation process to produce acetylene.Its technical process comprises three main equipment, i.e. cracking apparatus, gas booster compressor and concentrate equipment, and three equipment are whole constitutes a set of apparatus for producing ethyne for this.Cracking apparatus sets up 1 ~ 6 can the partial oxidation reactor of isolated operation, and it is 7500 tons that separate unit partial oxidation reactor produces acetylene per year.Main component CH in Sweet natural gas
4, when for hypoxgia, carry out partial oxidation reaction and obtain the reacted gas that acetylene content is about 8% (volume fraction).Reacted gas after cooling and dedusting, is sent to gas booster compressor.This equipment is provided with 2 compressors, and every compressor can meet the service requirements of 1 ~ 3 partial oxidation reactor simultaneously.The reacted gas of concentrate equipment concentrate is sent in compressed boosting afterwards, and by the process such as repeatedly selective absorbing, desorb etc. of solvent, reacted gas is separated into product acetylene, tail gas, mixture three kinds of components containing senior alkynes gas.
As the gas holder of surge tank, it is between cracking apparatus and gas booster compressor, is used for storing the reacted gas of coming from cracking apparatus.When whole device Load adjustment, the gas holder of setting can carry out dash adjustment, and Load adjustment balances; When whole device generation emergency episode, the cracking tolerance in gas holder, can allow concentrate equipment safety operation 3 to 6 minutes, and this period of surge time is used in the use of short period of time accident treatment and downstream concentrate equipment parking.Wet gasholder conventional in industry, its volume capacity is 10000m
3, cost is higher, is about 700 ~ 8,000,000 yuan, and this gas holder floor space is comparatively large, and construction duration is very very long.In existing production, a set of acetylene unit is produced and is just configured with a gas holder, there is the very large wasting of resources.
Summary of the invention
The object of the present invention is to provide a kind of device for the production of acetylene, the arrangement achieves the interconnected operation of two cover acetylene units.
Another object of the present invention is to the using method providing a kind of device for the production of acetylene, the method can control two cover acetylene units and share a gas holder safely.
The object of the present invention is achieved like this: a kind of device for the production of acetylene, it comprises two cover acetylene units, and wherein, the cracking apparatus in two cover acetylene units is communicated with a shared gas holder, this gas holder, by connecting tube, is communicated with two gas booster compressors overlapped in acetylene unit.
Another object of the present invention is achieved in that a kind of using method of the device for the production of acetylene, and it adopts the above-mentioned device for the production of acetylene; When cracking apparatus A and B all open 4 ~ 6 partial oxidation reactors normally run time, gas booster compressor A or B has a compressor to stop, then cracking apparatus A or B two partial oxidation reactors stop supplying gas to gas booster compressor, and the reacted gas that these two partial oxidation reactors produce are delivered to the torch burning of cracking apparatus A or B simultaneously; When cracking apparatus A and B all open 4 ~ 6 partial oxidation reactors normally run time, gas booster compressor A or B compressor full cut-off car, then cracking apparatus A or B stops three partial oxidation reactors to supply gas to gas booster compressor, and the reacted gas that these three partial oxidation reactors produce is delivered to the torch burning of cracking apparatus A or B simultaneously, remaining partial oxidation reactor of corresponding cracking apparatus stops; When gas holder deposit tolerance arrive gas holder height 83% time, cracking apparatus A and B partial oxidation reactor all stop; When gas booster compressor A and B all stops, cracking apparatus A and B all stops; When gas holder deposit tolerance arrive gas holder height 83%, and when gas booster compressor A and B all stops simultaneously, three partial oxidation reactors of cracking apparatus A or B stop, and close the unstripped gas of these three partial oxidation reactors simultaneously, and the fuel gas of Sweet natural gas preheating oven, open the valve of supplying gas of these three partial oxidation reactors, the reacted gas in gas holder is discharged into the torch burning of cracking apparatus A or B, and remaining partial oxidation reactor of cracking apparatus A and B stops.
For the production of the device of acetylene in the present invention, achieve the interconnected operation of two cover acetylene units, decrease the setting of gas holder, saved fund, and then saved the configuration of the resource such as construction period and related land.This using method, two cover acetylene units are made to share a gas holder safely, meet two cover acetylene unit Load adjustment poising action requirements, avoid when the stoppage in transit of some equipment or gas flow controlled not at that time, the devices such as gas holder can be caused to be pumped into vacuum, and then to cause equipment damage, or can due to excessive delivering gas, and it is quick-fried to cause gas holder to rise, the appearance of the problems such as reacted gas house steward and the rising of partial oxidation reactor system pressure.
Accompanying drawing explanation
Fig. 1 arbitraryly in embodiment of the present invention 1-3 described shares the structural representation of the method for gas holder for the production of two cover acetylene units in the device of acetylene.
