Abstract
The utility model relates to a sampler for collecting various kinds of smokes in a flue. A suction pump is arranged in a casing, and is connected with a connection pipe; one end of an air flow meter is connected with the connection pipe, and the other end of the air flow meter is connected with a sampling tube; and the sampling tube is connected with a gas absorption bottom arranged outside. A check valve capable of being opened to the receiving end only is mounted in the sampling tube. During sampling, the suction pump is started to suck the smoke in the flue to be determined into the sampling tube, and the high-pressure gas remaining after the gas absorption liquid in the gas absorption bottle absorbs the harmful gases pushes to open the check valve in the connection pipe, and then is discharged by the suction pump. After the suction pump is closed, the check valve capable of being opened to the receiving end only can not be opened to the reverse direction although the sampling end has large negative pressure, so as to prevent the smoke collected in the absorption bottle from being sucked back. The smoke sampler has the advantages of simple and reasonable structure, low manufacture cost, and is convenient in operation.
Description
Technical field
The utility model relates to a kind of sampling thief of gathering various flue gases in the flue.
Background technology
Whether up to standard for the fume emission of effectively grasping enterprise, must detect in real time this discharged flue gas, and detect the flue gas sample that just needs to gather in the flue.Gather the interior aspiration pump of housing of the sampling thief of flue gas, aspiration pump is connected with the gas absorption bottle of outside by sampling pipe 3, the connecting pipe 1 that has air volume meter 2 to be communicated with in the housing 6.Need to detect, when gathering, open aspiration pump, just can gather in real time.But after turning off air pump,, can exist the smoke absorption liquid of gathering in the absorption bottle, must be solved this suck-back problem by suck-back because the negative pressure of sampling end is big.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of smoke absorption liquid that can effectively prevent to gather in the absorption bottle by the anti-back suction type flue gas sampling thief of suck-back.
The implementation of the utility model purpose is, anti-back suction type flue gas sampling thief, aspiration pump is arranged in the housing, aspiration pump is taken in succession, air volume meter one termination connecting pipe, one termination sampling pipe, sampling pipe connect the gas absorption bottle of outside, and being equipped with in sampling pipe can only be to the retaining valve of receiving end unlatching.
The utility model is equipped with in sampling pipe can only be to the retaining valve of receiving end unlatching, when need are sampled, open air pump, flue gas in the tested flue is sucked in the sampling pipe, absorb gases at high pressure behind the harmful smoke by the absorption liquid in the gas absorption bottle and push retaining valve in the sampling pipe open, enter aspiration pump and discharge.After turning off air pump,, can only can not be reversed and push open to the retaining valve of receiving end unlatching, can not exist the smoke absorption liquid of gathering in the absorption bottle by the problem of suck-back because of being equipped with in the sampling pipe though the negative pressure of sampling end is big.
The utility model is simple and reasonable, easy and simple to handle, low cost of manufacture.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the one-way valve structures synoptic diagram.
Embodiment
The utility model is described in detail in detail with reference to the accompanying drawings.
With reference to Fig. 1, aspiration pump 5 is arranged in the housing 6, aspiration pump 5 takes over 1 in succession, the sampling pipe 3 that has air volume meter 2 to be communicated with in the housing 6, sampling pipe 3 connects the gas absorption bottle of outside, and being equipped with in sampling pipe can only be to the retaining valve 4 of receiving end unlatching.
With reference to Fig. 2, four hinges 8 are housed on the valve body 7 of retaining valve 4,9, four valve sheets 9 of valve sheet are housed on each hinge seal whole valve.
The utility model is equipped with in sampling pipe can only be to the retaining valve 4 of receiving end unlatching.When need are sampled, open aspiration pump 5, the flue gas in the tested flue is sucked in the sampling pipe, absorbs gases at high pressure behind the harmful smoke by the absorption liquid in the gas absorption bottle and pushes retaining valve in the sampling pipe open, enters aspiration pump 5 and discharges.After turning off air pump,, can only can not be reversed and push open to the retaining valve of receiving end unlatching, can not exist the smoke absorption liquid of gathering in the absorption bottle by the problem of suck-back because of being equipped with in the sampling pipe though the negative pressure of sampling end is big.
Retaining valve also can be contained in the connecting pipe 1.
The utility model is simple and reasonable, easy and simple to handle, low cost of manufacture.
