Description
Technical field
This utility model relates to coal-burning boiler denitrating system technical field, especially a kind of packaged type denitrating system flue gas concentration test device.
Background technology
Nitrogen oxides (NO, NO2 etc. are called for short NOx) is one of Air Pollutants of combustion of fossil fuel generation, and NOx generates nitric acid with the water in air and oxygen reaction, is the significant contributor of acid rain；The NOx of high concentration has strong impulse to respiratory system；NOx produces photochemical fog by photochemical reaction, and photochemical fog affects visibility, stimulates eyes and the respiratory system of people, and one of main matter in photochemical fog is O3, and O3 is a kind of gas to respiratory tract with intense stimulus.Visible, people, plant, building and environment are caused significantly harm by NOx directly or indirectly.From the point of view of world wide, one of fuel combustion main source main for NOx during especially coal fired power generation is air.Increase along with fired power generating unit and being continuously increased of generated energy, if not taking effective control measure, expect 2020 and 2030, whole nation NOx discharge capacity is up to 2363～29,140,000 tons and 3154～42,960,000 tons, the U.S. will be exceeded become the big NOx of the first in the world and discharge state, and thermal power generation NOx discharge will account for the ratio of total emission volumn and is up to about 50%.
Therefore flue gas needs to carry out denitration work before discharging.Widespread practice is to spray into ammonia in flue gas now, makes nitrogen oxides be reduced to harmless nitrogen.If spray ammonia is too much, the ammonia not reacted stays the secondary pollution belonging to artificial in flue gas, if the ammonia of spray is very few, does not reaches again the effect sloughing nitrogen oxides, it is therefore desirable to the content of the ammonia in flue gas after mensuration process.Mostly using field investigation and sampling for the test of NH3 Yu SO3 content in flue gas at present, the mode of laboratory measurement is carried out.In sampling process, cold easy condensation is met for NH3 Yu SO3, it is easier to the equipment that is sampled absorb, is also faced with dust content high, on problems such as result of the test impact are bigger, meanwhile, existing denitrating system flue gas content measuring system fails to test the flue gas content of multiple spot simultaneously.

Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, a kind of packaged type denitrating system flue gas concentration test device, this device includes moveable test carriage 1 and by connecting several testing tubes 3 that pipeline 2 is connected with test carriage 1, and described testing tube 3 is connected with flue, for testing the flue gas concentration within flue；Described test carriage 1, for showing the test data of described testing tube 3, described testing tube 3 is circumferentially provided with multiple smoke detectors 5.Multiple testing tubes 3 can monitor flue gas composition and the concentration of multiple positions from gas approach to exhanst gas outlet in flue simultaneously, and is provided with multiple smoke detectors 5 on testing tube 3, it is possible to the flue gas composition of differing heights and concentration in monitoring flue；Multiple smoke detectors 5 record the data of the flue gas composition in flue and concentration simultaneously, solve time prior art can only be monitored by single-sensor, the problem that and data time-consuming long to multiple positions detection in flue exist hysteresis quality and inaccuracy.By test carriage 1, can show that multiple smoke detectors 5 monitors the test data obtained.
Preferably: described smoke detectors 5 is NH3Sensor and/or NO sensor and/or SO3Sensor and/or humidity sensor and/or temperature sensor.On gas sensor 3, integrated multiple gases monitors probe, can detect flue gas composition and the concentration composition thereof of this position simultaneously, and monitoring process from each other of popping one's head in and Monitoring Data are independent of each other, and can guarantee that the data measured by sensor are true and accurate.
Preferably: described testing tube 3 is arranged in flue, shown test carriage 1 is can be at the vehicle of ground moving.By test carriage 1, movably multiple different local flues are carried out flue gas concentration monitoring, past tester needs at high aerial work, and the environment of operation simultaneously is narrow and small and the passageway of high temperature, and tester also cannot work long hours under this working environment.And by this utility model, tester just can record to obtain the flue gas concentration of multiple positions in flue on the test carriage 1 on ground, convenient and data are the most accurate.
Preferably: the described smoke detectors 5 protected cover of outer enclosure 6, described protective cover 6 has air inlet 7.Outside smoke detectors 5, it is provided with protective cover 6, the protective effect to smoke detectors 5 can be realized, because changing the relatively costly, so protective cover 6 can be avoided in operation owing to smoke detectors 5 is caused damage by the reasons such as collision of smoke detectors 5.
Preferably: on described test carriage 1, be provided with flow pump, it is connected with described testing tube 3 and the flue gas that testing tube 3 extracts is transported on described test carriage 1.Being extracted on test carriage 1 by the flue gas that testing tube 3 extracts by flow pump, tester just can record to obtain flue gas composition in high aerial flue and the data of concentration in terrestrial operation.
Preferably: described flow pump is also associated with flue gas concentration tester, for calculating, analyze the test data of described testing tube 33.The usual volume of flue gas concentration tester is relatively big, and inconvenience is mobile, and flue gas concentration tester and flow pump are all arranged on test carriage 1 by this utility model, is realized the mobility of denitrating system flue gas concentration test device by the movement of test carriage 1, facilitates human users.
Preferably: be provided with firing equipment in described connection pipeline 2, heating for described connection pipeline 2, heating temperature range is 120 DEG C-180 DEG C.Being learnt by practice, connecting best results when the temperature in pipeline 2 is 150 DEG C, at such a temperature, the steam being possible to prevent in flue gas meets condensation knot during being drawn into test carriage 1, impacts other smoke components, so that test data are inaccurate.
