Description
Technical field
The present invention relates to a kind of improved sampler, especially relate to a kind of gas sampling device with stainless steel pipes.
Background technology
Traditional sampler of using is at present carbon steel material, and sampling medium is reformed gas, and composition has carbon dioxide, water vapor, hydrogen etc., belongs to sour environment, current material corrosion-vulnerable, change stainless steel into after acid resistance improve; In addition, in the middle of traditional sampler, without filtering and purifying, when impurity flows in impurity and pipeline in gas, be accumulated in coil pipe in cooler place, after blocking pipe, cannot carry out normal gas-sample analysis.Its pipeline is carbon steel pipe, sampling medium is the combination gas of reformed gas hydrogen, methane, carbon monoxide, carbon dioxide, water vapor, and having catalyst dust, pipeline is easily corroded and stops up, and the situation that holds one's breath and cannot sample has occurred in actual use procedure to stop up.
And traditional sampler structure size is large, for non-continuous sampling, each sample volume is few, and institute's sample thief is real is residual gas in previous sample separation vessel storage tank, can not guarantee the real-time accuracy of analyzing.Traditional sampler is provided with refrigeratory and circulating water line is installed, and has limited the position of installation direction and the arm of Trunk Line.For above defect, sampler of the present invention is all steel device, size is little, gas storage freshness is high, the filtration unit of installing can filtration, purification sampler inlet gas, and sampling gas velocity flow is little, depending merely on the storage water of internal tank or temperature outdoor environment when low all can cooling sampling gas, need not set up separately circulation.
Summary of the invention
Gas sample collector of the present invention is to have solved former sampler material to be subject to sour gas corrosion and pipeline without gas filtration purified treatment problem.Independent cooling water circulation pipe design and installation work have been saved in the place of simultaneously getting chilled water inconvenience in order to meet.
A gas sampling device, mainly comprises stainless steel pipes, stainless steel filter, refrigeratory, sampler; Wherein stainless steel pipes one end is connected with reformed gas outlet by stop valve, and the other end is connected with refrigeratory by stop valve, and refrigeratory connects sampler, and sampler connects stopple coupon by sample valve; The outer wall of refrigeratory is welded by stainless-steel tube and end socket, inside establishes Stainless Steel Coil; Sampler is welded by stainless-steel tube and end socket, and inside is provided with hydraulic barrier and porous moisture trap.
It is 8mm that stainless steel pipes adopts diameter, and length is 3000mm.The stainless-steel tube diameter of described sampler is 80mm, and length is 300mm.The stainless-steel tube diameter of described refrigeratory is 100mm, and length is 400mm.
It is that 8mm, length are 3000mm stainless steel pipes and after stop valve, increase a stainless steel filter that sampler of the present invention is designed to diameter, in stainless steel sampling cooler, establish coil pipe, gas and water separator (porous plate, baffle plate) is set, better separated and purification sampling gas in separation vessel.
A gas sampling device, mainly comprises that diameter is that 8mm, length are more than or equal to 4000mm stainless steel pipes, stainless steel filter, sampler; Wherein stainless steel pipes one end is connected with reformed gas outlet by stop valve, and stainless steel filter is installed on the stainless steel pipes after stop valve, and the other end of stainless steel pipes connects sampler, and sampler connects stopple coupon by sample valve; Sampler is that 80mm, length are that 300mm stainless-steel tube and end socket are welded by diameter, and inside is provided with hydraulic barrier and porous moisture trap.
Through using and calculate, flow velocity and the flow of sampling gas are very little, only by the heat exchange of stopple coupon self, be enough to reduce reformed gas 360 and spend to normal temperature, when stopple coupon ￠ 8 length are more than or equal to 4 meters, refrigeratory can, only need just sampling of a water separator.
Sampling system is established two stop valves, during sampling, first drives outlet valve, then drives admission valve, after purging sampler, samples.
accompanying drawing explanation
Fig. 1 is reformed gas sampler structural drawing;
Fig. 2 is porous moisture trap structural drawing;
Fig. 3 is sampling flowsheet schematic diagram of the present invention.
Embodiment
Fig. 1 is reformed gas sampler structural drawing, and 1 is refrigeratory, and 2 is stainless steel pipes, and 3 is moisture trap, and 4 is hydraulic barrier.
1) sampling entrance is established stop valve, can on-bne repair while guaranteeing sampler fault.
2) on sampling pipe, establish stainless steel filter, the impurity in filtration, purification gas.
3) sampling pipe adopts the stainless steel small pipeline of Φ 8*2, and length has 3 meters, and middle with being threaded, gas flow rate and flow are little, are convenient to the cooling effectiveness in process.
4) sampler is with refrigeratory, and stainless-steel tube and end socket that container is DN100 are welded, and length is 400mm left and right, water storage 3KG left and right, and the gas cooled in the time of meeting sampling, sampling interval time is 4 hours, the water being heated in process is cooling naturally already also.
5) in sampler for DN80 stainless-steel tube and end socket are welded, length is about 300mm, inside is provided with hydraulic barrier and porous moisture trap, is convenient to the isolated by filtration of air water.
Sampling flowsheet of the present invention is, reformed gas in stop valve enters stainless steel pipes through stainless steel filter, the impurity in filtration, purification gas, condensation in refrigeratory, enters and in sampler, realizes gas-water separation.
Through using and calculate, flow velocity and the flow of sampling gas are very little, only by the heat exchange of stopple coupon self, be enough to reduce reformed gas 360 and spend to normal temperature, when stopple coupon ￠ 8 length are more than or equal to 4 meters, refrigeratory can, only need just sampling of a water separator.
Compare with existing best technique, the invention has the advantages that: be convenient to field fabrication and install, saved material and cost, extended serviceable life and reduced the possibility that fault occurs.The present invention by experiment, and actual use, effect is very desirable.Consistent with the expection of design.
