Abstract
The utility model relates to diesel oil hydrogenation process units, particularly relates to the attemperation apparatus that diesel oil hydrogenation raw material is online.Diesel oil hydrogenation raw material online attemperation apparatus is quantitatively carried, is mixed through multiple blender, reach multiple raw material and carry out quantitative, mixed uniformly object after plurality of raw materials being pressurizeed by some feedstock pumps.The utility model can adjust the ratio of each component timely, and does not take larger material-compound tank.
Description
Technical field
The utility model relates to diesel oil hydrogenation process units, particularly relates to the attemperation apparatus that diesel oil hydrogenation raw material is online.
Background technology
At present, the requirement of diesel hydrotreating unit to raw material is more and more stricter, for the raw material sources that small-sized refinery is unstable, ensure that the raw material of diesel hydrotreating unit is stablized several different raw material to be in harmonious proportion together, need the raw material be in harmonious proportion also to be unstable, this is need constantly adjustment with regard to causing various original proportioning simultaneously.For such mediation if utilize large tank to carry out, will unusual trouble once the material chemical examination prepared is undesirable, also have because the continuous change of blend component needs constantly to adjust proportioning, large tank is in harmonious proportion and cannot meets.
Summary of the invention
The utility model is exactly for the deficiencies in the prior art, provides one with need of production, can carry out the device of mediation raw material at any time.The utility model can adjust the ratio of each component timely, and does not take larger material-compound tank.
The technical scheme that the utility model provides is:
The online attemperation apparatus of diesel oil hydrogenation raw material, feedstock pump a connects the inflow entrance of the first blender straight tube by pipeline, pipeline between feedstock pump a and the first blender is disposed with control valve a and flowmeter a, is also connected by flow controller a between control valve a and flowmeter a; Feedstock pump b connects the bend pipe of the first blender by pipeline, the pipeline between feedstock pump b and the first blender is disposed with control valve b and flowmeter b, is also connected by flow controller b between control valve b and flowmeter b; The flow export of the first blender is connected with the inflow entrance of the second blender straight tube, feedstock pump c connects the inflow entrance of the second blender straight tube by pipeline, pipeline between feedstock pump c and the second blender is disposed with control valve c and flowmeter c, also connected by flow controller b between control valve b and flowmeter b, described first blender is identical with the second mixer structure, first blender is made up of bend pipe and straight tube, and the port of export of bend pipe is provided with helical blade.
Concrete, described bend pipe is 90 ° and bends.
Preferably, the inflow entrance to straight tube is rectified in the outlet of bend pipe.
The utility model design science is reasonable, can adjust the ratio of each component timely, and proportioning precisely, evenly; The utility model mechanism is simple in addition, is convenient to manufacture, not by the impact of space size, cheap.

Detailed description of the invention
The online attemperation apparatus of diesel oil hydrogenation raw material, feedstock pump a connects the inflow entrance of the first blender straight tube by pipeline, pipeline between feedstock pump a and the first blender is disposed with control valve a and flowmeter a, is also connected by flow controller a between control valve a and flowmeter a; Feedstock pump b connects the bend pipe of the first blender by pipeline, the pipeline between feedstock pump b and the first blender is disposed with control valve b and flowmeter b, is also connected by flow controller b between control valve b and flowmeter b; The flow export of the first blender is connected with the inflow entrance of the second blender straight tube, feedstock pump c connects the inflow entrance of the second blender straight tube by pipeline, pipeline between feedstock pump c and the second blender is disposed with control valve c and flowmeter c, is also connected by flow controller b between control valve b and flowmeter b; Described first blender is identical with the second mixer structure; First blender is made up of bend pipe and straight tube, and the port of export of bend pipe is provided with helical blade, and described bend pipe is 90 ° and bends, and the inflow entrance to straight tube is rectified in the outlet of bend pipe.
The utility model is applicable to two kinds or more raw materials for being in harmonious proportion, and raw material A, raw material B and raw material C, respectively in different storage tanks, first determine to each raw material analysis the ratio needing proportioning before using.In each flow controller, input the flow of each component, carry out by each control valve the flow controlling each component respectively, proportioning can be completed accurately.When needs adjustment proportioning, only need the flow inputting needs in corresponding discharge controller.Plurality of raw materials can carry out evenly, fast mixing by the first blender and the second blender by the utility model, generating portion can not mix uneven problem.
The raw material entered by the bend pipe of blender, the helical blade through winding pipe exit end rotates and moves ahead, and in the process of moving ahead, and the raw material that straight tube enters mixes gradually, makes mixing more even.The raw material entered by straight tube can be avoided the direct impact of bend pipe, avoid the situation appearance that bend pipe raw material is trapped in winding pipe exit place, there will not be the situation of raw material incomplete mixing.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
