Abstract
The utility model relates to an anti-corrosion and anti-plugging sheath of a flue gas probe. The anti-corrosion and anti-plugging sheath comprises a flange disk fixedly connected with the probe and a sleeve the diameter of which is matched with that of the probe, wherein the flange disk is fixedly connected with one end of the sleeve; the probe extends into the inner side of the sleeve through a center hole of the flange disk; at least two stop sheets are arranged in the other half section relative to the sleeve; every two adjacent stop sheets are staggered to form an S-shaped flue gas channel. Due to the heating function of the probe, heat extends into the sleeve, so that flue gas can be heated when entering the sleeve but not the probe, and generated coagulated solid substances can be retained at the outer section of the sleeve; due to the S-shaped channel formed by the stop sheets in the sleeve, the time for heating flue gas in the sleeve can be prolonged, so that the effect is further enhanced, and flue gas entering the probe cannot be coagulated to plug the probe.
Description
Technical field
The utility model relates to a kind of probe protective device, specifically a kind of flue gas probe corrosion-and blocking-prevention plug sheath.
Background technology
Present protective jacket adopts stainless steel filtering net or ceramic element substantially in the short time, can play a role for wet desulphurization substantially, but the time be easy to stop up after long, cause and cannot measure.Flue gas is inner by entering probe in normal temperature flue gas, and due to the heating function of probe, flue gas can be heated in probe, makes probe obstruction with the flue gas of the desulfurization slurry gypsum crystal that freeze-outs.
Summary of the invention
For preventing that flue gas from stopping up probe entering to produce to condense after probe, the utility model provides a kind of flue gas probe corrosion-and blocking-prevention plug sheath, comprise one with the fixing ring flange of popping one's head in, one with the sleeve of probe diameter adaptation; Described ring flange and sleeve one end are affixed, and probe stretches into sleeve inner side by the center pit of ring flange, and second half intersegmental part that described sleeve is relative is provided with at least two catch, faces mutually two catch and is crisscross arranged, and forms the exhaust gases passes of S shape.
Due to the heating function of probe itself, heat can extend in sleeve, and flue gas is just heated in the time entering sleeve but do not enter probe, produces the solid matter condensing and can stay the outer section of sleeve.And catch forms the heat time of S shape passage meeting prolong smoke in sleeve in sleeve, further stiffening effect, the flue gas that enters probe can not produce to condense again and stop up probe.
Accompanying drawing explanation
Fig. 1 the utility model one-piece construction schematic diagram;
Fig. 2 is A-A line cut-open view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is illustrated:
Probe is for measuring the concentration of sulfur dioxide in flue gas, flue gas there will be some impurity to stop up and denude probe entering after probe, cause determination data inaccurate or cannot use, present means of defence mainly adopts at probe oral area installation stainless steel filtering net or ceramic element flue gas is filtered, but these methods only have effect at short notice, and effect is undesirable.
After further research, the upper intrinsic heating function of dilution method probe, is for preventing flue gas condensing, and measurements of sulfur dioxide concentration value diminished, but heating chemical in flue gas can produce to condense and being attached to that probe is upper to be stopped up or abrasion is popped one's head in.Simple effective method is before flue gas enters probe, first gives flue gas, allows the flue gas gypsum crystal that tentatively freeze-outs, then sends in probe.Heating-up temperature in probe, in 300 degree left and right, installs a sleeve additional outside probe, and the heat of probe can extend in sleeve, and it is heated that flue gas enters sleeve, outside probe, just can complete and condense.Coagulum is kept in sleeve and can itself exert an influence to popping one's head in.
The concrete scheme of the utility model as shown in Figure 1, 2, a kind of flue gas probe corrosion-and blocking-prevention plug sheath, comprises ring flange 1, sleeve 2, catch 4, and described ring flange 1 is affixed with sleeve 2 one end, probe 3 stretches in sleeve 2 by the center pit of ring flange 1, is fixed on probe 3 by ring flange 1.Second half intersegmental part that described sleeve 2 is relative is provided with some catch 4, faces mutually two catch 4 up and down or left and rights and is crisscross arranged, and forms S shape exhaust gases passes.
When use, this sheath is enclosed within on probe 1; sheath and probe 3 are connected and fixed with ring flange 1; when coagulum is too much, sheath can be taken off and clean or change; the utility model adopts the original heating function of probe, and flue gas point is moved outward, makes flue gas just complete and condense entering before probe; catch forms the heat time of S shape passage meeting prolong smoke in sleeve; further stiffening effect, makes flue gas can probe not produced and be stopped up or abrasion, well protection probe.
Claims (1)
1. a flue gas probe corrosion-and blocking-prevention plug sheath, is characterized in that: comprise one with the fixing ring flange of probe, one with the sleeve of probe diameter adaptation; Described ring flange and sleeve one end are affixed, and probe stretches into sleeve inner side by the center pit of ring flange, and second half intersegmental part that described sleeve is relative is provided with at least two catch, faces mutually two catch and is crisscross arranged, and forms the exhaust gases passes of S shape.
