An aromatization feeding vaporizer for high-efficiently avoiding coking of reactors belongs to the field of light dydrocarbon aromatization equipment, and is characterized in that the vaporizer is integrally shaped into a trapezium with a large bottom and a small top, two ends of the vaporizer are respectively provided with a U-shaped tube heater, a tube pass I regards low-pressure steam as a hot source and is vertically connected with a steam inlet and a condensed liquid outlet, a tube pass II regards high-temperature condensed liquid as a hot source and is vertically connected with a hot water inlet and a hot water outlet, the top of a shell pass is connected with a feed liquid inlet, a feed gas outlet, a washing liquid connector, an automatic-control liquid level gauge connector and a field/remote thermometer connector, and a heavy constitute outlet is disposed between the two tube passes at the bottom of the vaporizer. The aromatization feeding vaporizer for high-efficiently avoiding coking of reactors is simple in structure, convenient in installation, large in feed vaporization treatment quantity and strong in capability of removing dicyclopentadiene coking factors, achieves 100% removing efficiency, high-efficiently lowers following aromatization reaction coking efficiency without cleaning troubles, and saves energy by 30% compared with modes of electric heating and the like.
Description
Technical field
The utility model belongs to light-hydrocarbon aromatized apparatus field, is specifically related to a kind of efficient anti-coking aromizing charging vaporizer.
Background technology
The vaporizer situation is various at present, action principle is roughly the same, all be when using " liquid state " petroleum gas than the big customer at the oil liquefied gas amount, by vaporizer will " liquid phase " be converted into " gas phase ", solve the problem that can't satisfy the demand of the ability of vaporizing voluntarily during low temperature again of liquid lng in the container.Vaporizer structure use respectively alludes to.Such as, electric heating carburetor is to design and develop for the big gas user of liquefied petroleum gas (LPG), is with the combustion gas pressure regulation of vaporizing, heating water temperature control and show integrated a kind of device.Gasification burner utilizes low power consumption, the direct heating mode, and oil liquefied gas, propane flammable gas, butagas is heated to design temperature, is mainly the raising calorific value, increases intensity of fire.Most small-sized vaporizer all is generally to use for all trades and professions such as industrial use, restaurant, restaurant, life kitchens.Electrothermal water bath type is mainly used in the independent liquefied petroleum gas supply website that substitutes the extensive network gas transmission, is applicable to industrial and mining enterprises, thermal treatment, spraying coating line, stove, the large, medium and small restaurant of food catering trade, hotel heat supply and residential quarter central gas supply.Common these models are various, volume is little, treatment capacity is low, power consumption is high, be suitable for dingus vaporization raw material.
Summary of the invention
The utility model emphasis in the lower carbon number hydrocarbons feed vaporization scarce capacity that solves aromatization is the dicyclopentadiene in the pretreating raw material, stops the coking factor to enter reactor, realizes efficiently preventing reactor coking purpose.
The following technical scheme of the concrete employing of the utility model:
A kind of aromizing charging vaporizer that efficiently prevents the reactor coking, it is characterized in that, described vaporizer integral body is the little trapezoidal moulding in big top, the end, respectively there is a U-shaped pipe heater at two ends, tube side I is thermal source with the low-pressure steam, be connected to the outlet of steam inlet and lime set up and down, tube side II is a thermal source with the high temperature lime set, be connected to hot water inlet and hot water outlet up and down, the shell side top is connected to stock liquid import, unstripped gas outlet, washing lotion interface, automatic control interface of the level gauge, scene/teletransmission thermometer boss, is provided with the heavy constituent outlet between two tube sides of bottom.
The utility model is mainly the problem that easy coking molecule that solve to remove in the aromatization of low carbon hydrocarbon raw material and lower carbon number hydrocarbons can not fully vaporize in use and develops.
The utility model adopts high temperature lime set hot water and low-pressure steam as thermal source, make the oligomeric one-tenth compound precipitation of dicyclopentadiene in the stock liquid in the oligopolymer bag by the DCS controlled temperature, discharging regularly, in the time of when jello is gathered in two tube side walls or stops up outlet, can resting in system with suitable solvent oil washing lotion soaking and washing.
The utility model has solved feed vaporization scarce capacity problem simultaneously.Have following characteristics:
(1) simple, the simple installation of equipment.
(2) moulding meets the vaporization characteristics, perfect in shape and function, safety, reliable.
(3) thermal source wide ranges, suitability is big.
(4) can need design the vaporization energy force parameter at chemical plant installations, lower carbon number hydrocarbons feed vaporization processing power is big, 100% vaporization in vaporizer.
(5) liquid level, temperature DCS regulate, and be quick, accurate, time saving and energy saving.
(6) unique oligopolymer bag designs, and 100% removes the coking factor.
(7) unique oligopolymer purging method cleans the coking material.
(8) waste heat on the chemical plant installations is utilized energy-conserving and environment-protective.
