Description
Technical field
The present invention proposes a kind of method for designing that is used for the coke-oven gas sampler, especially at continuous environment at the line extraction coke-oven gas.
Background technology
For the steel-making industry, output, the quality requirements of iron are higher.Coke is the main material of blast furnace ironmaking, and it is mainly obtained at coking chamber by raw coal, and the coal resources of China are very abundant, so the coke industry is to have very big use.And the coke-oven gas that produces in process of coking is the fuel of high heat value, it is again the important organic synthesis raw material of industry, contain explosive gases such as hydrogen and methane in the gas, and low boilers and sulfide such as a large amount of tar, benzene, naphthalene, background gas composition complexity.Therefore, in order to improve the control to coal-gas recovering technology, strengthen security, improve rate of energy, the coke-oven gas sampling method mainly contains two classes at present, promptly online and sampling formula.Thereby online analysis mainly is to adopt the adsorption rate different compositions that obtain in gas gas of gas with various to light, but, gas is rich in tar, benzene, the material of the easy crystallization of equivalent low boiling how because gathering, so needing high pure nitrogen purges in emission laser port and reception place, and can divide dilution with the sample pneumatolytic in the flue like this, make assay value on the low side.The crucial sampling probe equipment that the sampling formula is analyzed, what produced by Siemens Company at present is a kind of sampling method of pneumatic extraction probe, the starter gear sealing that this method need be taken a sample is very good, and the compressed gas source of certain pressure will be provided, be convenient to extract probe and when overhaul of the equipments, probe extracted.For the sampling formula, owing to contain the material of easy crystallization in the sample gas, therefore can often stop up probe, thereby cause the big and waste resource of maintenance capacity.
Summary of the invention
The present invention discloses a kind of device that can continuous drawing sample gas, and this device mainly partly is made up of cooling control system, sampling system etc.Wherein the external refrigeration control system comprises stainless steel fixedly body, two spiral refrigerators that are welded in stainless steel stationary pipes body side surface and the top cover of popping one's head in; Two entrance pressures contract air scoop respectively by two spiral refrigerators and stainless steel fixedly body be connected.The stainless steel that above-mentioned inner sampling system is positioned at the external refrigeration control system is body fixedly, and from being made up of the composite ceramic stopple coupon of first order stainless steel screen pack, first fluororubber sealing gasket, second level stainless steel screen pack, second fluororubber sealing gasket and infundibulate lined ceramics film successively down, the sample introduction gas port is connected by second manual ball valve and infundibulate lined ceramics film composite type pottery stopple coupon inner sampling system by last.Above-mentioned inner sampling system and above-mentioned stainless steel fixedly between the body space be refrigerating channel; The position that above-mentioned probe top cover keeps to the side has the gas outlet that communicates with refrigerating channel, and the emptying controller is installed on the gas outlet; The middle part of above-mentioned probe top cover has the gas port that communicates with inner sampling system, goes out the sample gas port and is connected with above-mentioned gas port by first manual ball valve, advances the blowback steam port and is connected with above-mentioned gas port by electrical ball valve.
The cooling control system major function is that the temperature that guarantees the inner space is in temperature constant state; adopt adjustable compression air eddy refrigerator to freeze; carry out the adjusting of inner space temperature according to the internal temperature conversion; internal temperature is remained in the certain limit; purpose is the rapid crystallization of material that helps tar, benzene, how to wait easy crystallization; outer wall is made up of stainless-steel tube simultaneously, total system is had the effect of an overfill protection.The sampling system major function is to guarantee the unobstructed of sample gas passage, and guaranteeing does not simultaneously have entering of other non-sample pneumatolytics branches, guarantees the authenticity of sample gas, adopts the sampling pipe of the composite ceramic pipe of resistant to elevated temperatures lined ceramics film as coke-oven gas.Use this device can extract true sample gas safely.
The advantage of device disclosed by the invention is as follows:
(1) has continuity.Because the internal layer ceramic membrane has good adsorbability, can bear the variation of internal and external temperature, and can not be out of shape, therefore, the sampling probe of this device can the stable work of continuity.
(2) has nonstaining property.The cooling system of device adopts the vortex refrigerator, directly uses pressurized air to freeze, thus the gas that it gives off to atmosphere without any pollution, and ceramic membrane can reclaim the processing back and reuses.
(3) has higher security: because ceramic membrane and ceramic stopple coupon all have good stability and inoxidizability, so can stop vortex refrigerator cold air to enter stopple coupon well, thereby guaranteed the security of sampling, outside simultaneously employing stainless steel is fixed, and system is stablized and safety more in sampling process.
Description of drawings
Fig. 1 is the device synoptic diagram of continuous drawing coke-oven gas sample gas, and Fig. 2 is for changing the ceramic membrane synoptic diagram: 1: the first manual ball valve, 2: electrical ball valve, 3: the sampling probe top cover, 4: the first stainless steel wire web filters, 5: the first fluororubber sealing gaskets, 6: the second stainless steel wire web filters, 7: the second fluororubber sealing gaskets, 8: stainless steel is body fixedly, and 9: vortex refrigerator, 10: lined ceramics film composite type pottery stopple coupon, 11: the second manual ball valves, 12: the emptying controller.13: gas outlet, 14: go out the sample gas port, 15: advance the blowback steam port, 16: the entrance pressure air scoop that contracts, 17: the sample introduction gas port.18: ceramic membrane.
Embodiment
At first with stainless steel fixedly body 8 lump together with vortex refrigerator 9 soldering group, then stainless steel is popped one's head in top cover and stainless steel fixedly body 8 welding finish, ceramic membrane 18 and ceramic stopple coupon are with reference to Fig. 2 method, adopt special gluing being connected together (will be convenient to raise after attention and ceramic pipe are outside bonding), form lined ceramics film composite type pottery stopple coupon, purpose is to be convenient to dismounting next time, and then with in its solid body 8 of packing into, the second fluororubber sealing gasket 7 of packing into successively, the second stainless steel wire web filter 6, the first fluororubber sealing gasket, 5, the first stainless steel wire web filters 4.When needs are changed, be reversed in this way and get final product, also can be with reference to shown in Figure 2.
Owing to contain high viscosity, the easy crystallised components of low boiling such as tar, benzene, the bitter edible plant in the coke-oven gas, so when sample gas passes through the ceramic stopple coupon of the lined ceramics film under the built-in cold air effect, basically all understand crystallisation by cooling, bond on the ceramic membrane of inner pipe wall of ceramic pipe.When a loop ends, purge with high pressure steam, the crystalline solid on the inwall all will be blown off, and crystalline solid is easy to blow out from pipeline, and do not influence use next time of sampling probe.When probe does not use, second manual ball valve 11 and first manual ball valve 1 can be closed simultaneously.
