Abstract
The utility model discloses a stifled device is prevented to thick liquid attitude bed reactor distributor, it includes the raw materials trachea, prevents stifled pipe, three way connection, middling pressure nitrogen gas pipe, high -pressure nitrogen gas pipe, is equipped with gaseous check valve on the gas access pipeline of thick liquid attitude bed reactor distributor, is equipped with the feed gas trip valve on the raw materials trachea, be equipped with on preventing stifled pipe and prevent stifled trip valve, be equipped with middling pressure nitrogen gas trip valve on middling pressure nitrogen gas pipe, be equipped with high -pressure nitrogen gas trip valve on the high pressure nitrogen gas pipe. The advantage: the chemical plant is because of shaking reasons such as electricity or equipment trouble when leading to air supply power to disappear, and the feed gas trip valve is closed immediately, prevents stifled trip valve, middling pressure nitrogen gas trip valve and opens immediately, for thick liquid attitude bed reactor distributor provides incessant air supply power, avoids the thick liquid to subside down to the distributor inside, prevents that the distributor from blockking up, and then extension distributor life, and it parks to reduce overhauls the number of times.
Description
Technical field:
The utility model relates to a kind of anti-block apparatus, relates in particular to a kind of paste state bed reactor distributor anti-block apparatus.
Background technology
Under normal circumstances, paste state bed reactor is by clean unit 3.2MPa, 220 DEG C, the unstripped gas of total sulfur content < 0.05ppm, reactor bottom distributor is passed into after mixing with 3.2MPa, the circulation synthesis gas of 205 DEG C, the gaseous mixture entering paste state bed reactor passes through to contain the slurries bed of catalyst with the form of bubbling, carry out F-T synthetic reaction.But chemical plant duration causes source of the gas power to disappear because shaking the reason such as electricity or equipment fault, the source of the gas power of paste state bed reactor is once disappear, and slurries just can, down to distributor inside, cause distributor block, the service life of reduction distributor; Be difficult to Hand scarf after slurries poured into by distributor go out, serious words need parking maintenance to clear up, and the cycle of parking maintenance is longer; And process of stopping is also larger on catalyst activity impact; After distributor blocking, resistance increases, and cause recycle gas compressor load to increase electric current and raise, motor longtime running exists hidden trouble of equipment.
Utility model content:
The purpose of this utility model is to provide a kind of paste state bed reactor distributor anti-block apparatus that can effectively prevent distributor from blocking.
The utility model is implemented by following technical scheme: paste state bed reactor distributor anti-block apparatus, it comprises raw material tracheae, pipe-blocking-proof, three-way connection, medium pressure nitrogen tracheae, elevated pressure nitrogen tracheae, the gas access pipeline of paste state bed reactor distributor is provided with gas check valve, described gas access pipeline inlet end is connected with described raw material tracheae one end, and described raw material tracheae is provided with unstripped gas stop valve; Described pipe-blocking-proof one end is connected with the described raw material tracheae between described unstripped gas stop valve and described gas check valve, and the described pipe-blocking-proof other end is connected with described three-way connection first end, and described pipe-blocking-proof is provided with anti-blocking stop valve; Described three-way connection second end is connected with described medium pressure nitrogen tracheae one end, and described medium pressure nitrogen tracheae is provided with medium pressure nitrogen gas stop valve; Described three-way connection the 3rd end is connected with described elevated pressure nitrogen tracheae one end, and described elevated pressure nitrogen tracheae is provided with high pressure nitrogen stop valve.
Advantage of the present utility model: chemical plant because of shake the reason such as electricity or equipment fault cause source of the gas power to disappear time, unstripped gas stop valve cuts out immediately, anti-blocking stop valve, medium pressure nitrogen gas stop valve are opened immediately, for paste state bed reactor distributor provides uninterrupted source of the gas power, avoid slurries sedimentation down to distributor inside, prevent distributor from blocking, and then extend distributor service life, reduce parking maintenance number of times.
Accompanying drawing illustrates:
Fig. 1 is overall structure schematic diagram of the present utility model.
Raw material tracheae 1, pipe-blocking-proof 2, three-way connection 3, medium pressure nitrogen tracheae 4, elevated pressure nitrogen tracheae 5, suction line 6, gas check valve 7, unstripped gas stop valve 8, anti-blocking stop valve 9, medium pressure nitrogen gas stop valve 10, high pressure nitrogen stop valve 11.
Detailed description of the invention:
As shown in Figure 1, paste state bed reactor distributor anti-block apparatus, it comprises raw material tracheae 1, pipe-blocking-proof 2, three-way connection 3, medium pressure nitrogen tracheae 4, elevated pressure nitrogen tracheae 5, the gas access pipeline 6 of paste state bed reactor distributor is provided with gas check valve 7, gas access pipeline 6 one inlet end is connected with raw material tracheae 1 one end, raw material tracheae 1 other end is connected with raw material source of the gas, and raw material tracheae 1 is provided with unstripped gas stop valve 8; Pipe-blocking-proof 2 one end is connected with the raw material tracheae 1 between unstripped gas stop valve 8 and gas check valve 7, and pipe-blocking-proof 2 other end is connected with three-way connection 3 first end, and pipe-blocking-proof 2 is provided with anti-blocking stop valve 9; Three-way connection 3 second end is connected with medium pressure nitrogen tracheae 4 one end, and medium pressure nitrogen tracheae 4 other end is connected with medium pressure nitrogen gas source of the gas, and medium pressure nitrogen tracheae 4 is provided with medium pressure nitrogen gas stop valve 10; Three-way connection 3 the 3rd end is connected with elevated pressure nitrogen tracheae 5 one end, and elevated pressure nitrogen tracheae 5 other end is connected with high pressure nitrogen source of the gas, and elevated pressure nitrogen tracheae 5 is provided with high pressure nitrogen stop valve 11.
Operation principle: when system is normally run, open gas check valve 7, unstripped gas stop valve 8 and high pressure nitrogen stop valve 11, close anti-blocking stop valve 9 and medium pressure nitrogen gas stop valve 10, unstripped gas is delivered in distributor through raw material tracheae 1, suction line 6, simultaneously, high pressure nitrogen enters in pipe-blocking-proof 2 between anti-blocking stop valve 9 and medium pressure nitrogen gas stop valve 10 and medium pressure nitrogen tracheae 4 through elevated pressure nitrogen tracheae 5 and forms high pressure " sealing gland ", and when avoiding medium pressure nitrogen tracheae 4 pressure low, process gas falls string in medium pressure nitrogen tracheae 4; When having a power failure or other reasons causes source of the gas power to disappear, closing unstripped gas stop valve 8 and high pressure nitrogen stop valve 11, in distributor, supplementing medium pressure nitrogen gas through medium pressure nitrogen tracheae 4 and pipe-blocking-proof 2, ensure that distributor has sufficient source of the gas power bubbling; Avoid slurries sedimentation down to distributor inside, prevent distributor from blocking, and then extend distributor service life, reduce parking maintenance number of times.
