Description
One, technical field
The utility model relates to chemical technology field, a kind of depolymerization kettle adds in specifically a kind of gasoline anti-knock agent MMT production
Expect device.
Two, background technique
MMT full name is methyl cyclopentyl-dialkyl-tricarbon manganium, is a kind of unleaded gas anti-knock agent haveing excellent performance, and prepares work
Skill are as follows: methyl cycle pentadiene dimer Pintsch process is generated into methyl cyclopentadiene, tetrahydrofuran and gold are added in ring sodium kettle
Belong to sodium, methyl cyclopentadiene is added dropwise into kettle, after metallic sodium fully reacting, by ring sodium it is hydraulic enter ring manganese kettle, anhydrous chlorine is added
Change manganese, heating reaction obtains ring manganese liquid, by ring manganese it is hydraulic enter carbonylation kettle in heat up and be filled with high pressure carbon monoxide carry out
Carbonylation, the material after reaction enter in distillation still, tetrahydrofuran and methyl cyclopentadiene three in step by step arithmetic material
Manganese carbonyl (MMT), solid waste discharge centralized processing, tetrahydrofuran are recycled, and MMT is further purified and obtained qualified products.
It is direct from methyl cycle pentadiene dimer that existing methyl cycle pentadiene dimer Pintsch process, which generates methyl cyclopentadiene device,
It is fed to depolymerization kettle, is disposable intermittent charging, causes that depolymerization kettle yield is low, and utilization rate of equipment and installations is insufficient, high production cost.
Three, summary of the invention
The utility model aim: the utility model provides a kind of depolymerization kettle feeding device in order to solve the above problem.
The content of the utility model: a kind of depolymerization kettle feeding device, including double methyl cyclopentadiene storage tanks, depolymerization kettle, company
Adapter tube line and DCS control system are provided with pans in connecting pipeline between double methyl cyclopentadiene storage tanks, depolymerization kettle, described
Pans discharge port setting height is higher than the pan feeding open height of depolymerization kettle, and pans discharge port connect defeated with depolymerization kettle feeding inlet
Check valve and flowmeter are set on pipeline out, and the pans are the narrow infundibulate closed container in top width bottom, and the side wall of pans is set
It is equipped with remote liquid level metering device, the remote liquid level metering device signal output end is connected by signal wire and DCS control system
It connects, is provided with gas vent at the top of pans.
Remote liquid level metering device is external magnetic double level gauge described in further technical solution.
Further technical solution pans are internally provided with filter plate.
The utility model is changed to continuous feed the utility model has the advantages that increase intermediate storage tank, disposable charging, and intermediate storage tank is set
Intelligent liquid level control device is set, is improved work efficiency, yield is improved.
Four, Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein 1 pair of methyl cyclopentadiene storage tank, 2 depolymerization kettles, 3 discharge pipelines, 4 pan feeding pipelines, 5 material pump, 6 pans, 7 far
Pass magnetic double level gauge, 8 check valves, 9 flowmeters, 10 gas vents, 11 filter plates.
Five, specific embodiment
The utility model is illustrated in conjunction with attached drawing, a kind of depolymerization kettle feeding device, including the storage of double methyl cyclopentadienes
Tank 1, depolymerization kettle 2, connecting pipeline and DCS control system are set in connecting pipeline between double methyl cyclopentadiene storage tanks 1, depolymerization kettle 2
Be equipped with pans 6,6 discharge port of the pans setting height is higher than the pan feeding open height of depolymerization kettle 2,6 discharge port of pans with
Check valve 8 and flowmeter 9 are set on the discharging pipeline 3 of 2 feeding inlet of depolymerization kettle connection, and the pans 6 are the narrow funnel in top width bottom
Shape closed container, the side wall of pans 6 are provided with teletransmission magnetic double level gauge 7, and 7 signal output end of magnetic double level gauge is logical
It crosses signal wire to connect with DCS control system, is provided with gas vent 10 at the top of pans, pans are internally provided with filter plate 11.
Device working principle and the course of work are to set the teletransmission magnetic double level gauge 7 of pans 6, when 6 liquid level of pans is low,
Teletransmission magnetic double level gauge 7 exports corresponding signal, is transferred to DSC control system by signal wire, the sending of DSC control system is set
The enabling signal of the material pump 5 on pan feeding pipeline 4 is set, the raw material in double methyl cyclopentadiene storage tanks 1 is squeezed into pans by material pump 5
6, after the filter plate 11 in pans 6, the discharge nozzle for being provided with check valve 8 and flowmeter 9 through by 6 discharge port of pans
Line 3 enters depolymerization kettle 2, and when 6 liquid level of pans is high, teletransmission magnetic double level gauge 7 exports corresponding signal and passes through signal wire
It is transferred to DSC control system, DSC control system sends out the shutdown signal of discharging pump 5, the liquid level of pans 6 is kept, on pans 6
Top is provided with gas vent 10, can effectively prevent the vibration for causing pans 6 in liquid charging stock or in pipeline with gas.
