The corresponding relation of component names and Reference numeral is among Fig. 1:
Valve part 4.
Embodiment
Core of the present invention is for providing a kind of process analysis procedure analysis sampling system, this process analysis procedure analysis sampling system is provided with heating component and the cleaning assembly to clearing up after the stopple coupon sampling that stopple coupon is heated, by its structural design, can solve the fouling blockage problem of sampling line.
In order to make those skilled in the art understand better technical scheme of the present invention, the present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1, Fig. 1 is the structural representation of process analysis procedure analysis sampling system in an embodiment of the present invention.
The invention provides a kind of process analysis procedure analysis sampling system, be used for the liquid towards material and take a sample, especially the sampling liquid with high concentration, thickness, easily fouling is taken a sample, comprise sampling pump 1 and the stopple coupon 2 that is connected with sampling pump 1.Stopple coupon 2 is connected with the mass transport pipeline, provides sampling power by sampling pump 1, can be with the Liquid extracting in the mass transport pipeline out, and generally speaking, the exit of sampling pump 1 can be provided with sampling cup and be used for taking up sample.The problem that fouling stops up occurs for fear of the present invention and occur, the process analysis procedure analysis sampling system also comprises: the heating component that can heat stopple coupon 2; And can carry out the cleaning assembly 3 that wind is swept the formula cleaning to stopple coupon 2.
Need to analyze the reason that blockage problem appears in sampling system at this, by background technology as can be known, resulted in blockage two and comparatively typically formed reason: first is exactly the sample crystallization; Second is exactly the fouling of material (sample) residual settlement.Therefore, can draw the reason of the problem of resulting in blockage: the first, stopple coupon 2 is because heat conduction has reduced sample temperature; The second, there is sample residual in the stopple coupon 2.
By above-mentioned plugging reason, the present invention proposes following solution: arranging at stopple coupon 2 can be to its heating component that heats, so that in the scope that the temperature of stopple coupon 2 keeps being close with sample temperature, solved thus the problem that the sample crystal is separated out; Set up stopple coupon 2 is carried out the cleaning assembly 3 that wind is swept the formula cleaning, be used for after sampling finishes stopple coupon 2 being carried out the pipeline cleaning, it is residual to avoid sample occurring, and this structure has solved in the stopple coupon 2 owing to there being the residual stopple coupon that causes 2 of sample to stop up.
Need to prove that at this present invention adopts wind to sweep the cleaning assembly 3 of formula cleaning, its purpose is: can not cause substantial effect to the physical property of sample, avoid causing the distortion of Monitoring Data or the impact that product is caused.Because sample objects of the present invention is liquid, therefore, if adopt liquid substances that stopple coupon 2 is cleared up, easily so that cleaning enters into sample or product with liquid, cause the change of the physical property of sample or product, such as reducing sample concentration, in product, introducing impurity etc.And, adopt wind to sweep the cleaning assembly 3 of formula cleaning and can also be directly blow back to the mass transport pipeline the sample in the stopple coupon 2 is residual, avoid product to waste.
Particularly, in a specific embodiment of the present invention, heating component is electric-heating belt, and heating component axially evenly coats along it in the outside of stopple coupon 2, and is fixed on the stopple coupon 2 by heat proof material.
Electric-heating belt is to be made of conducting polymer and two parallel metal wire and insulation sheath.Be characterized in that conducting polymer has very high ptc characteristics, and in parallel mutually, can be with the automatic regulation output power of the temperature variation that is heated system, the temperature of volitional check heating, arbitrarily brachymemma or within the specific limits spreading use.Heating component axially evenly coats along it in the outside of stopple coupon 2, can so that the heating-up temperature on the stopple coupon 2 be consistent.
Heating component can also adopt spiral heater, and the resistive heater uniform winding of spiral heater on stopple coupon 2, can be heated stopple coupon 2 equally.
For the efficiency of heating surface that improves heating component and the heating energy consumption that reduces heating component, in the present embodiment, the outside of heating component also is enclosed with heat-insulation layer, heat scattered and disappeared when heat-insulation layer can reduce heating component to stopple coupon 2 heating, the heat that farthest heating component is produced is stored in the heat-insulation layer, so can accelerate the firing rate of heating component, and reduce energy consumption by insulation effect.Heat-insulation layer can adopt asbestos insulations, or polyfoam, mineral wool goods, foamglass, expansion pearlite thermal insulation product etc.
In order to carry out comparatively accurate temperature control to stopple coupon 2, the present invention is provided with the temperature sensor that can measure the heating component temperature between stopple coupon 2 and heat-insulation layer, control the holding temperature of heating component by the temperature feedback of temperature sensor.As the optimization to above-described embodiment, the present invention also provides central control system, and central control system receives the temperature detection signal of temperature sensor, and this temperature detection signal is analyzed comparison, then control the startup of heating component or close, thereby realize intelligent control of the present invention.
Particularly, in a specific embodiment of the present invention, cleaning assembly 3 comprises: be arranged at the threeway parts 31 on the stopple coupon 2; The air pump 32 that is communicated with threeway parts 31.
Particularly, in a specific embodiment of the present invention, cleaning assembly 3 can directly be introduced air compression system, is communicated with stopple coupon 2 by threeway parts 31, so can also carry out the cleaning of high efficient and reliable to stopple coupon 2 by high pressure air.
In the said structure design, in case open cleaning assembly 3, cleaning assembly 3 will be cleared up whole stopple coupon 2 simultaneously, and it is specially: simultaneously threeway parts 31 are cleared up near a lateral line of sampling pump 1 and threeway parts 31 are cleared up near a lateral line of mass transport pipeline.
For pipeline that can threeway parts 31 both sides is realized respectively cleaning, valve part 4 also is provided in the present embodiment, air pump 32, sampling pump 1 and valve part 4 are communicated with three installing ports of threeway parts 31 respectively.
When the mass transport pipe pressure is larger, a valve is set between air pump 32 and mass transport pipeline, at first open valve, be sampled in the sampling cup by sampling pump 1 again; Take a sample complete after, open sampling pump 1, open air pump 32 residual material of sampling pump 1 front and back blowed to sampling cup, close again sampling pump 1, open valve, by air pump 32 the residual mass transport pipeline that blows to of material between valve and the mass transport.
More than a kind of process analysis procedure analysis sampling system provided by the present invention has been carried out detailed Jie used specific case herein principle of the present invention and embodiment set forth, the explanation of embodiment just is used for helping to understand method of the present invention and core concept thereof.Should go out, for those skilled in the art, put not breaking away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modifying in the protection domain of also claim of the present invention.
