Description
Technical field
The utility model relates to a kind of stationary source flue gas particles collecting device, especially a kind of can intelligent constant-temperature heating, make flue gas enter collect or separation equipment before the rear-mounted sampling gun of flue gas particles of the unlikely reduction of temperature.
Background technology
Flue gas particles sampling gun used, is divided into sample pre-process formula and the large class of rearmounted processing formula two at present.Carrying out PM
2.5when monitoring, because separating, the equipment volume of different-grain diameter particle is large is inconvenient to put into flue, needs to use rearmounted processing formula sampling gun, at PM
2.5in sampling process, find a shortcoming of the current method of sampling: when cavity temperature is lower than cigarette temperature in sampling gun, the easy condensation of moisture in flue gas, thereby be bonded on sampling gun inwall, likely other composition adhesions of flue gas are taken out of, make the smoke components and the primitive component that arrive rearmounted treating apparatus have difference, causing can not Measurement accuracy smoke components.This is because existing sampling gun, what have does not possess heating function completely, what have only possesses part pipeline section heating function, so, without the heating pipeline section without heat insulation function of naked leakage outside thief hatch in surrounding air, because the gap of ambient temperature and cigarette temperature is larger, pipeline section temperature is well below cigarette temperature, flue gas enter sampling gun back segment because the temperature difference is prone to above problem.
Current solution is, in sampling location, to be wound around long heating tape temporarily, then to wrap one layer of heat preservation cotton for insulation outside the sampling gun pipeline section without heating function.But heating tape temp. control function is simpler, a heating tape can only maintain temperature in a certain fixed value or close limit, carries and is wound around heating and thermal insulation equipment temporarily, has also increased sample devices volume and personnel's workload.
At present shortage can free adjustment and is observed heating-up temperature, and maintains heated at constant temperature, and rear-mounted sampling gun easy to carry and use, can be applicable to the monitoring of the flue gas of rear-mounted sampling.
Summary of the invention
For the deficiency of existing sampling gun, the purpose of this utility model be to propose a kind of can whole tube section heating, keep in cavity temperature identical with cigarette temperature, can intelligent constant-temperature heat, be convenient to intuitive operation, there is larger temperature applicable range, can withstand high temperatures, the flue gas particles sampling gun of corrosive gas, be applicable to the situation of smoke post processing.
In order to achieve the above object, the technical scheme that the utility model is taked is: a kind of intelligent constant-temperature heating flue gas particles sampling gun, connected to form successively by sampling elbow 13, hard sampling pipe 1, handle 2, sampling flexible pipe 3, described hard sampling pipe 1 and sampling flexible pipe 3 innermost layers are wireway 5, in wireway 5 outsides, zone of heating 6 is all set, the outer heat-insulation layer 11 that arranges of zone of heating 6; Attemperating unit 4 is set on handle 2, comprises the aobvious control system 9 of temperature and earth leakage protective device 10.
A temperature sensor 8 is installed between described wireway 5 and zone of heating 6, and hard sampling pipe 1 front end arranges cigarette temperature probe 7, and temperature sensor 8, cigarette temperature probe 7, zone of heating 6 are connected with the aobvious control system 9 of temperature.
Because connected charged equipment on sampling gun, for protection operator's personal safety, on handle, install earth leakage protective device 10 additional.The aobvious control system 9 of temperature comprises a LCDs that can show the gentle wireway heating-up temperature of cigarette, and the temperature control knob of adjustable heating-up temperature.
The utility model advantage is compared with the existing technology:
1, can whole tube section heating, the adjustable and heated at constant temperature of temperature.When sampling, heating-up temperature is set for to cigarette temperature value, be heated to cigarette Wen Houke and maintain constant temperature.This makes air guide inner tube smoke can maintain all the time initial temperature before the rearmounted flue gas processing device of arrival, adsorbs the component in flue gas while avoiding moisture to separate out, makes measured value inaccurate.
2, operation is flexibly directly perceived.Temperature display control device and cigarette temperature probe, temperature sensor are housed, can check the gentle wireway heating-up temperature of cigarette from liquid crystal display at any time, usable temp control knob regulates heating-up temperature.Intuitive and convenient, is used flexibly.If sample when environment temperature is too low, even if heating-up temperature is identical with cigarette temperature, wireway temperature also may be lower than cigarette temperature, now can be according to the temperature conditions of liquid crystal display, and heating-up temperature suitably raises.
3, larger temperature applicable range.Wireway, exterior material all use exotic material, and zone of heating is selected exotic material composition heater coil, makes sampling gun can tolerate the temperature of 300 DEG C, and this makes sampling gun range of application larger.
4, protection user safety.Sampling gun needs operator hand-held, and crust of the device has conductive material, and there is again electric heater unit inside, needs defence electric leakage situation to occur.Therefore earth leakage protective device is installed in design additional, can auto-breaking protection operator personal safety in the time that sampling gun leaks electricity.
