1) high humidity gas in stove flow out until be cooled to 130 DEG C from about 800 DEG C in the pipeline of one section, detector ingress; the large quantity of moisture condensed out in this temperature-fall period is trapped in pipeline and cannot removes in time; signal piping is caused to block and detected value fluctuation; cause annealing furnace auto stop time serious, bring impact to safety in production.
2) if on sampling line coated lagging material, though can reduce hydrogenesis, sample temperature spends height can be affected measuring accuracy and cause analytical instrument to damage, and adds production cost, also for manual maintenance makes troubles.
3) current common moisture separation device is substantially all baffle plate type structure, complex structural designs, by a large amount of welding; some row complete processings such as casting; cost is high and separation efficiency is low, and sepn process pressure drop is obvious, and the inapplicable sampling being installed on annealing furnace shielding gas detects pipe network.
4) owing to being hydrogen rich gas atmosphere in annealing furnace, all contain a large amount of hydrogen in the moisture that the gas after detection and condensation go out, direct designing and arranging is put exists severe compromise in an atmosphere.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of telescoping reflux cooler, by sample gas sampling line and return line are arranged to sleeve pipe near a section of annealing furnace, separating effect can be improved, water of condensation can be made again to gasify immediately when flowing back in stove, avoid the precision affecting furnace annealing atmosphere, while energy-saving and emission-reduction, achieve cost efficiency.
The present invention is achieved in that a kind of telescoping reflux cooler, comprise housing and atmosphere cooling body, described atmosphere cooling body is arranged on the middle part of housing, described housing bottom has water port, case top is connected with atmosphere detector by outlet pipe, water port is connected with the detection mouth of annealing furnace by return line, atmosphere import is provided with below the middle part of housing, described atmosphere import is connected with the detection mouth of annealing furnace by sample gas sampling line, described sample gas sampling line is sleeved in return line near a section of annealing furnace, the height of described water port is higher than the detection mouth of annealing furnace.
Described atmosphere cooling body is made up of one-level condensation blade and secondary heat exchange coil pipe, and described one-level condensation blade is arranged on the below of secondary heat exchange coil pipe, and described secondary heat exchange coil pipe is connected with exterior cooling water loop.
Described one-level condensation blade is some blades with certain radian, and blade level is arranged on the housing between secondary heat exchange coil pipe and atmosphere import.
The angle of described return line length direction and housing bottom surface is 40 ° ~ 80 °.
The length of the described return line be sleeved on outside sample gas sampling line is 2/3 of return line total length.
When telescoping reflux cooler of the present invention detects, in stove, sampled atmosphere is tentatively cooled at the sleeve portion of sample gas sampling line and return line, to be cooled by coil heat exchange again and the centrifugation of condensation blade isolates water of condensation, water vapor in the abundant condensation sample gas of energy, good separating effect, water of condensation is in return line flow is melted down, avoid rich hydrogen water of condensation and directly discharge the potential safety hazard brought, in reflux course, water of condensation also can carry out heat exchange with sample gas, the water of condensation with certain temperature can gasify immediately when flowing back in stove, avoid the precision affecting furnace annealing atmosphere, sample gas sampling line and return line also can be used as the pressure equilibrium pipeline of water cooler and annealing furnace atmosphere in addition, when in housing, water of condensation liquid level reach a certain height, when in housing, gaseous tension and water of condensation column pressure are greater than furnace pressure, drive condensate return, prevent reflux course water of condensation from being returned in housing by the furnace gas blowback entering return line simultaneously, guarantee the stable of reflux course.
The present invention is being applied to good separation after on continuous annealing unit, and there is adaptability and compatibility widely, can be applicable to the band steel continuous processor group that other has similar demand, and while energy-saving and emission-reduction, achieve cost efficiency, be achieve many things at one stroke, advocate today of environmental protection in country energetically, possess high promotional value.
