Abstract
The utility model discloses a smoke sampling exploring tube or pitot tube with a film heating and heat tracing device, which is composed of a smoke sampling exploring tube or pitot tube, an electrical heating film, a thermal insulating layer and a sleeve tube. The smoke sampling exploring tube or pitot tube with the film heating and heat tracing device is characterized in that the electrical heating film is tightly stuck with the smoke sampling exploring tube or pitot tube, the electrical heating film and the smoke sampling exploring tube or pitot tube are packaged by the thermal insulating layer, and the sleeve tube is sheathed outside the thermal insulating layer. The smoke sampling exploring tube or pitot tube adopts the film heating and heat tracing device to automatically trace heat to generate a micro-thermal environment, so that the smoke sampling exploring tube or pitot tube can prevent dew condensation and corrosion, the interference of smoke water droplets is reduced, and the corrosion resisting performance and the long-term reliability of the smoke sampling exploring tube or pitot tube are increased.
Description
Technical field
The utility model relates to flue gas sampling inserting tube or the pitot tube that a kind of high-temperature flue gas sampling equipment is used, and is a kind of flue gas sampling inserting tube or pitot tube with film heating companion thermic devices specifically.
Background technology
In the high-temperature flue gas testing, flue gas sampling inserting tube and pitot tube are to detect the most frequently used sampling device of sample devices/instrument.Generally can have dust and acidic materials such as SO2, NOX etc. in the flue gas, how solve effectively that sampling feeler lever and the pitot tube that smoke moisture is big, dust contained flue gas causes stops up, wear problem, be a difficult problem anxious to be solved in the CEMS fluid-velocity survey.Pitot tube that present common differential pressure fluid-velocity survey is used and sampling inserting tube, its dynamic pressure and static tube generally adopt stainless steel to add that the mode of stainless steel sheath solves corrosion and wear problem, can't overcome the strong acid etching problem that smoke condensation or liquid particles produce, can cause cost too high as the titanium alloy that adopts higher standard.
The utility model content
Problem to be solved in the utility model is to overcome the above-mentioned defective that prior art exists, and has proposed a kind of flue gas sampling inserting tube or pitot tube with film heating companion thermic devices.Adopt the built-in film heating of protecting pipe companion hot mode to solve the strong acid etching problem of smoke condensation or liquid particles generation, can effectively prolong the serviceable life of pitot tube, and improve the validity that pitot tube is measured, can solve the ubiquitous above-mentioned difficult problem of CEMS fluid-velocity survey effectively.
The utility model a kind of flue gas sampling inserting tube or pitot tube with film heating companion thermic devices, constitute by flue gas sampling inserting tube or pitot tube, electric heating film, heat-insulation layer, sleeve pipe, it is characterized in that: electric heating film is close to flue gas sampling inserting tube or pitot tube, heat-insulation layer is with electric heating film and flue gas sampling inserting tube or pitot tube parcel, and casing pipe sleeve is contained in outside the heat-insulation layer.
Further improvement project is: be provided with temperature sensor between flue gas sampling inserting tube or pitot tube and electric heating film, gather the temperature of flue gas sampling inserting tube or pitot tube, so that control the heater switch of electric heating film according to design temperature.
The utility model employing film heats companion's thermic devices and accompanies heat to produce the low-grade fever environment automatically, can make flue gas sampling inserting tube or pitot tube anti-condensation, anticorrosion, and the interference of minimizing flue gas water droplet improves the flue gas sampling inserting tube or pitot tube is corrosion-resistant and long-term reliability.
