Abstract
The utility model relates to a gas sampling device. A sampling pump and the working part of a grain separator are arranged in the inner chamber of a constant-temperature box; a sampling pipe is communicated with the inner chamber of the grain separator; the output pipe of the grain separator is communicated with a material inlet pipe of the sampling pump; the output pipe of the sampling pump is connected with a testing unit; a pump shaft of the sampling pump is connected with the output shaft of a motor out of the constant-temperature box; after entering the grain separator and the sampling pump, the sample gas is transmitted to a constant-temperature box and is then transmitted to an analyzer. The utility model has the advantages of keeping the sample gas at a constant temperature, avoiding the condensation of the sample gas, ensuring the stable components of the sample gas, and improving the measuring precision. The utility model is suitable for collecting the sample gas of the continuous online tail gas analysis system of the tail gas out of the engines, boilers, etc.
Description
The utility model relates to gas sampling assembly, particularly is suitable for the gas sampling assembly of gathering exhaust gases of internal combustion engines.
In the tail gas of engine exhaust, moisture is higher, the carbon soot particles of some and the gas of other composition are arranged, when adopting gas analyzer that the internal combustion engine discharge tail gas is detected, require sample gas cleaning, drying, no soot particle and aqueous vapor, the content of corrosive impurity is not more than every cubic metre of 0.01 gram, because may result in blockage after entering analyser greater than 1 micron particulate, influence the usability of instrument.The sampling apparatus of existing engine exhaust tail gas and particle sorting apparatus divide mostly and are arranged, because sample gas is before entering analyser, it is constant that its temperature can not keep, and flowing time is long, and variation has taken place sample pneumatolytic part, has influenced measuring accuracy.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of sample gas harvester that exhaust gases of internal combustion engines is used that detects is provided.
The technical solution of the utility model: contain motor, constant temperature oven, sampling pump, particle separator, the working position of sampling pump and particle separator all places the inner chamber of constant temperature oven, the inner chamber of stopple coupon and particle separator interlinks, the efferent duct of particle separator and the feed pipe of sampling pump interlink, the efferent duct of sampling pump connects test cell, and the pump shaft of sampling pump links to each other with the output shaft of constant temperature oven motor outward.
Because the working position of sampling pump of the present utility model and particle separator all places the inner chamber of constant temperature oven, sample gas all was in the constant temperature oven deliver to analyser after entering particle separator, sampling pump before, make sample gas keep steady temperature, the cooling and the moisture content condensation precipitation process of sample gas have been avoided, guarantee the stable of sample gas component, improved measuring accuracy.Be applicable to that the tail gas to equipment such as engine, boilers carries out the sample gas collection of continuous online exhaust gas analysis system.
Accompanying drawing has provided an embodiment of the present utility model:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A view of the utility model embodiment.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Adopt continuous type sampling pump 2 and particle separator 1 under the high temperature, the working position of sampling pump 2 and particle separator 1 all places the inner chamber of constant temperature oven 9, the filter core 3 excessively of particle separator 1 can be changed under hot conditions at any time, stopple coupon 8 interlinks with the inner chamber of particle separator 1, the feed pipe of the efferent duct of particle separator 1 and sampling pump 2 interlinks, the efferent duct 7 of sampling pump 2 connects test cell, and the pump shaft 4 of sampling pump 2 links to each other with the output shaft 5 of constant temperature oven 9 motor 6 outward.The pump shaft that motor 6 drives sampling pump 2 rotates, make sampling pump 2 inner chambers produce negative pressure, the tail gas of working equipment is pumped into the inner chamber of particle separator 1 through stopple coupon 8, by the filter core 3 crossed that is located in the particle separator 1 it is filtered, enter sampling pump 2 through the efferent duct of particle separator 1, the feed pipe of sampling pump 2 again, at last, by sampling pump 2 the sample air pump is delivered to test cell.Because the working position of sampling pump 2 and particle separator 1 all places the inner chamber of constant temperature oven 9, then the temperature in the temperature of the working position body of sampling pump 2 and particle separator 1 and the constant temperature oven 9 is consistent, the temperature of constant temperature oven 9 is to configure according to the temperature of tail gas in advance in addition, so, the temperature of delivering to the tail gas of the temperature of sample gas of test cell and working equipment is suitable, has kept the constant of sample temperature degree.The efferent duct 7 of the efferent duct of stopple coupon 8 of the present utility model, particle separator 1, the feed pipe of sampling pump 2, sampling pump 2 is stainless-steel tube; On constant temperature oven 9, also be provided with a temperature sensor, the temperature in convenient demonstration and the control constant temperature oven 9; Employing the utility model can be to the tail gas direct sample of equipment such as engine, boiler; sample gas acquisition component as continuous online exhaust gas analysis system; be used for the tail gas of internal combustion engine is taken a sample, can satisfy the sampling requirement of the exhaust emission standard regulation of Environmental Protection Agency (EPA) and European Union (EU) formulation.
