Description

A kind of flow control system of solar hydrogen-system making
Technical field
The present invention relates to a kind of flow control system of solar hydrogen-system making.
Background technology
Hydrogen is essential industry raw material, has the industrial chemicals of marketable value as produced combined diesel oil, formic acid, ammonia and methyl alcohol etc., and hydrogenation organic substance, as contraction gas, is used in oxyhydrogen flame fusion splicer and rocket fuel.At high temperature with hydrogen by metal oxide back to produce metal than additive method, the character of product is more easy to control, and simultaneously the purity of metal is also high.Be widely used in the production of the metal-powders such as tungsten, molybdenum, cobalt, iron and germanium, silicon.When hydrogen and oxygen chemical combination, release a large amount of heat, be utilized to carry out cutting metal.The energy produced during the nucleus fusion of the isotropic substance deuterium of hydrogen and tritium is utilized to generate electricity.Now, hydrogen also as the clean energy in a kind of future of substitutability, for the fuel of automobile etc.Current hydrogen producing technology, does not also use CO 2and H 2in conjunction with production formic acid, the technical matters of the organic raw material such as diesel oil, organic-fuel, route has high marketable value.The formic acid, the organic-fuel that generate, be equivalent to CO 2to clean fuel H 2serve storage and conveying effect.
summary of the invention:
The object of the invention is to for above-mentioned technical barrier, of the present invention being overcomes above deficiency, provides a kind of and uses CO 2and H 2in conjunction with production formic acid, the technical matters of the organic raw material such as diesel oil, organic-fuel.And the present invention is the flow control system being matched in a kind of solar hydrogen-system making.For achieving the above object, the technical solution used in the present invention is: the flow control system that the present invention relates to a kind of solar hydrogen-system making, comprise PC 1, RS232 universal serial bus 2, high pressure plunger pump frequency transformer 3, high-pressure plunger pump motor 4, flow control valve 5 form, it is characterized in that the flow control system of described a kind of solar hydrogen-system making takes high pressure plunger pump frequency transformer 3 to control at each high-pressure plunger pump motor 4, thus regulating flow.Described RS232 universal serial bus one end is connected with PC 1, and the other end high pressure plunger pump frequency transformer 3 connects.Described flow control valve 5 is arranged on cooler outlet.
advantage of the present invention is mainly reflected in:
Preheating water in guarantee system, material total flux stable; Ensure to enter the preheating water of each parallel reactor, the uniformly distributing of mass flow.
description of drawings 1, Fig. 2 area kind of flow control system of solar hydrogen-system making schematic diagram:
1-PC machine 2-RS232 universal serial bus 3-high pressure plunger pump frequency transformer 4-high-pressure plunger pump motor 5-flow control valve.
embodiment illustrates embodiment 1:
tell about below in conjunction with Fig. 1a kind of flow control system of solar hydrogen-system making composition:
The present invention relates to a kind of flow control system of solar hydrogen-system making, comprise PC 1, RS232 universal serial bus 2, high pressure plunger pump frequency transformer 3, high-pressure plunger pump motor 4, flow control valve 5 form, it is characterized in that the flow control system of described a kind of solar hydrogen-system making takes high pressure plunger pump frequency transformer 3 to control at each high-pressure plunger pump motor 4, thus regulating flow.Described RS232 universal serial bus one end is connected with PC 1, and the other end high pressure plunger pump frequency transformer 3 connects.Described flow control valve 5 is arranged on cooler outlet.
The target of flow control is: preheating water in 1, guarantee system, material total flux stable.2, ensure to enter the preheating water of each parallel reactor, the uniformly distributing of mass flow.
For target 1, the control mode taked is: before each high-pressure plunger pump motor 4, arrange mass rate measuring point.High pressure plunger pump frequency transformer 3 is taked to control to the motor of pump, thus regulating flow.
For the control that preheating water always flows.The magnitude relationship of preheating water flow to the gasification result of reactive system, meanwhile, the Working environment very severe of preheater.Therefore, most important to the control of preheating water flow.Due to the difference that preheating water total flux is the flow that outlet of plunger pump total flux and water cooler 1 export.Therefore its uninterrupted, control by the flow regulating preheating water outlet of plunger pump total flux and water cooler 1 to export.
For target 2, namely regulate and control the flow of each reactor branch road.For under the prerequisite that the flow deviation of distributing header is less, the control mode of suggestion is as follows: 1, adopt the mode of distributing header and combining with header, realize uniform divided flows.When each bypass duct of layout, ensure that each branch road tube side is close, header and pipeline structure symmetry as far as possible; 2, by reducing the thermal deviation of each fluidized-bed reactor, the resistance to flow deviation of each reactor is reduced, thus the material of each reactor balanced and preheating water flow.
