Description
Technical field
The utility model relates to coking industry fan blower machine oxygen on-line analysis monitoring equipment, particularly for the coke-oven gas device for filtering impurities of paramagnetic oxygen analyzer.
Background technology
Paramagnetic oxygen analyzer is the analyser equipment of the oxygen on-line analysis of coking industry fan blower machine and monitoring, and its effect is that the coke-oven gas introducing paramagnetic oxygen analyzer extracted by fan blower by gas sampling pipeline carries out on-line analysis.Owing to the analysis of coke-oven gas being the carrying out of on-line uninterruption, carried out on-line analysis and monitoring in the past, directly be incorporated into paramagnetic oxygen analytical equipment again analyze by extracting coke-oven gas in blower conduits, various impurity in coal gas are very many and be not easy to remove, therefore sampling line is easily caused to block, analyser failure rate is very high, is often in the malfunction stopping analyser.
Utility model content
Technical problem to be solved in the utility model is, effectively solves fan blower paramagnetic oxygen analyzer and to carry out in gas sampling process, due to the fault that impurity causes, providing the device for filtering impurities of a kind of on-line analysis and monitoring.
The utility model is achieved through the following technical solutions above-mentioned purpose, and coke-oven gas device for filtering impurities, comprises filtering water tank, and the bottom of filtering water tank is that its centre of pot bottom-shape is provided with blow-off pipe, and blow-off pipe is connected with blowoff valve; The side of filtering water tank is provided with drainpipe, and drainpipe is connected with draining valve; The top of filtering water tank is separately installed with gas inlet pipe, water inlet pipe and coal gas escape pipe, and gas inlet pipe is provided with gas admittance valve, and water inlet pipe is provided with water intaking valve, and coal gas escape pipe is provided with air outlet valve.
Described draft tube endpiece is positioned at the bottom of filtering water tank.
Described water inlet pipe endpiece is positioned at the middle part of filtering water tank.
Described escape pipe inlet end is positioned at the top of filtering water tank.
The utility model overcomes and solves the coal gas problem of pretreatment of existing paramagnetic oxygen analyzer existence; The fault that all kinds of impurity in effective removing coke-oven gas cause analyser.The site installation test of filtering water tank is convenient, simple; The importing of sampling coal gas, derivation rely on the gas pressure in gas piping to realize completely, on-the-spot without the need to any pressue device; Daily servicing, the maintenance of contaminant filter water pot are very simple, at the needs carrying out regular draining, water inlet can meet coal gas filtration completely; Cooperation paramagnetic oxygen analyzer completes the normal running to filtering water tank, can meet completely and reach the requirement of analyser to gas purification.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. gas inlet pipe, 2. gas admittance valve, 3. water inlet pipe, 4. water intaking valve, 5. coal gas escape pipe, 6. air outlet valve, 7. drainpipe, 8. draining valve, 9. blow-off pipe, 10. blowoff valve, 11. filtering water tanks.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and see Fig. 1, coke-oven gas device for filtering impurities, comprises filtering water tank 11, and the bottom of filtering water tank 11 is that its centre of pot bottom-shape is provided with blow-off pipe 9, and blow-off pipe 9 is connected with blowoff valve 10; The side of filtering water tank 11 is provided with drainpipe 7, and drainpipe 7 is connected with draining valve 8; The top of filtering water tank 11 is separately installed with gas inlet pipe 1, water inlet pipe 3 and coal gas escape pipe 5, and gas inlet pipe 1 is provided with gas admittance valve 2, and water inlet pipe 3 is provided with water intaking valve 4, and coal gas escape pipe 5 is provided with air outlet valve 6.
Described gas inlet pipe 1 endpiece is positioned at the bottom of filtering water tank 11.
Described water inlet pipe 3 endpiece is positioned at the middle part of filtering water tank 11.
Described coal gas escape pipe 5 inlet end is positioned at the top of filtering water tank 11.
embodiment:the entrance of the utility model gas inlet pipe 1 docks with sampling line, is directly introduced in filtering water tank 11 by coal gas.Filtering water tank 11 is in drum-shaped, and bottom is pot bottom-shape.The outlet of coal gas escape pipe 5 is docked with the entrance of gas analysis meter, is introduced in gas analysis meter by coal gas.Water is introduced by filtering water tank 11 top by water inlet pipe 3, and carries out water level detecting by drainpipe 7, by water lev el control at suitable height, ensures the effect that coal gas filters.For the impurity under filtering in coal gas, control to discharge by the blow-off pipe 9 bottom water pot and blowoff valve 10, according to the pollution level of effluent sewerage, determine that the interval time of water is changed in blowdown, ensure the effect that coal gas filters.
According to paramagnetic oxygen analyzer sampling line trend, in paramagnetic oxygen analyzer porch, the utility model is installed, utilizes filtering water tank 11 to filter and by the impurity filtering in coal gas, specific works process is as follows:
1) in filtering water tank 11, introduce the clear water of certain water level, its height of water level carries out the control of water level detecting mouth by drainpipe 7, the too high coal gas washed out of water level cannot enter in gas analysis meter smoothly, the coal gas of the too low importing of water level cannot effectively be filtered, and affects the analysis of next procedure to coal gas.The height of water level is 2/3 ~ 3/4 of filtering water tank 11 cavity heights.
2) gas sampling mouth to be positioned at after blower fan machine on gas piping, this place is always malleation 15-20KPa, and due to the effect of malleation, coal gas is imported filtering water tank 11 easily via gas inlet pipe 1 by coal gas, enter after fully exchanging with water bottom filtering water tank 11, the impurity in coal gas is deposited in water.
3) coal gas washed out from water, impurity wherein is filtered, and coal gas is derived to enter in paramagnetic oxygen analyzer by the outlet of coal gas tracheae 5 and analyzed.
The utility model is worked continuously for scene and uninterrupted on-line monitoring oxygen level; Much more very effectively can remove in the process of paramagnetic oxygen analyzer sampling for impurity all kinds of in coke-oven gas and ensure the normal work of analyser.The utility model not only with machine oxygen on-line analysis monitoring contaminant filter, also can be used for the contaminant filter of other similar field, has a extensive future.
