Abstract
The utility model provides a flue sampling device for corrosive gas. The flue sampling device comprises a sampling tube which is connected with a high-temperature flue and a buffer tank; the buffer tank is a sealed tank; a piston is arranged in the center of the buffer tank; the sampling tube extends into the buffer tank and is positioned on the upper part of the piston; an air pumping pipeline connected with an air pump extends into the buffer tube, penetrates through the piston and enters the lower part of the piston; a detection pipeline extends into the buffer tank, is positioned on the upper part of the piston and is connected with a detector; a one-way air inlet valve is arranged on the detection pipeline; an one-way air outlet valve is arranged on the sampling tube. By the fuel sampling device, the to-be-detected corrosive gas is prevented from corroding the air pump, and the service life of the air pump is prolonged.
Description
technical field:
The utility model relates to a kind of environmental monitoring utility appliance, is specifically related to a kind of for having the flue sampling apparatus of corrosive gas.
background technology:
Some corrosive gass, comprise sour gas, as chlorine, carbon dioxide, sulphuric dioxide, nitrogen dioxide, nitrogen trioxide, sulfuretted hydrogen, hydrogen chloride, hydrogen iodide, hydrogen bromide, hydrogen fluoride etc., also there is alkaline gas, as ammonia etc., also have some neutral toxic gases, as carbon monoxide and some chloridating gas, fluorinated gas is cyaniding gas even, these waste gas mainly come from chemical plant, metallurgical works, the industrial sectors such as garbage burning factory, this class waste gas contains a large amount of easily materials to environment, need to carry out sampling analysis, so that administer targetedly.
The taproot content of existing gas sampling assembly is all to adopt aspiration pump to carry out air suction sampling, but in the sampling process for corrosive gas, aspiration pump is subject to the impact of corrosive gas for a long time, the damage that is easily corroded of the inherent core component of aspiration pump, causes reduce the serviceable life of aspiration pump.
utility model content:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of for having the flue sampling apparatus of corrosive gas, avoid vacuum pump directly with the contacting of corrosive gas, the serviceable life of prolongation vacuum pump.
Above-mentioned object realizes by following technical scheme:
For thering is the flue sampling apparatus of corrosive gas, comprise the sampling pipe being connected with high-temperature flue, described sampling pipe connects surge tank, described surge tank is sealable tank, in the middle of described surge tank, be provided with piston, described sampling pipe stretches in described surge tank and is positioned at the top of described piston, pump-line stretches in described surge tank and through described piston and enters described piston bottom, described pump-line connects aspiration pump, detect the top that pipeline stretches in described surge tank and is positioned at described piston, described detection pipeline connects detector, on described detection pipeline, breather cheek valve is installed, unidirectional air outlet valve is installed on described sampling pipe.
Described for thering is the flue sampling apparatus of corrosive gas, on described pump-line, there is one section of flexible telescopic section, it is outside that described flexible telescopic section is positioned at described surge tank.
Described for having the flue sampling apparatus of corrosive gas, described sampling pipe is arranged on described high-temperature flue by support, and described sampling pipe stretches into the center of described high-temperature flue.
Beneficial effect:
1. the utility model is when aspiration pump is bled, surge tank bottom is in negative pressure state, piston moves down, thereby open the unidirectional air outlet valve on sampling pipe, the gas at high-temperature flue center enters surge tank and is positioned at piston top from sampling pipe, in the time of aspiration pump exhaust, piston bottom in surge tank is in high pressure conditions, on piston, move, open the breather cheek valve detecting on pipeline, gas enters detector, owing to driving piston up-down by aspiration pump, aspiration pump does not directly contact with gas to be detected, avoided the corrosion of corrosive gas to be detected to aspiration pump, extended the serviceable life of aspiration pump.
2. because pump-line is directly through piston, for the ease of piston up-down, have one section of flexible telescopic section on pump-line of the present utility model, it is outside that described flexible telescopic section is positioned at described surge tank.
3, in order to ensure the accuracy of sampling, the utility model, according to the requirement of standard, stretches into sampling pipe at the center of high-temperature flue and samples, accurately and reliably.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
In figure: 1, high-temperature flue, 2, sampling pipe, 3, surge tank, 4, piston, 5, pump-line, 6, aspiration pump, 7, detect pipeline, 8, detector, 9, breather cheek valve, 10, unidirectional air outlet valve, 11 flexible telescopic sections, 12, support.
embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand following embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.
Embodiment 1:
As shown in Figure 1: of the present utility model for thering is the flue sampling apparatus of corrosive gas, comprise the sampling pipe 2 being connected with high-temperature flue 1, described sampling pipe connects surge tank 3, described surge tank is sealable tank, in the middle of described surge tank, be provided with piston 4, described sampling pipe stretches in described surge tank and is positioned at the top of described piston, pump-line 5 stretches in described surge tank and through described piston and enters described piston bottom, described pump-line connects aspiration pump 6, detect the top that pipeline 7 stretches in described surge tank and is positioned at described piston, described detection pipeline connects detector 8, on described detection pipeline, breather cheek valve 9 is installed, unidirectional air outlet valve 10 is installed on described sampling pipe.
Embodiment 2:
Described in embodiment 1 for thering is the flue sampling apparatus of corrosive gas, on described pump-line, there is one section of flexible telescopic section 11, it is outside that described flexible telescopic section is positioned at described surge tank.
Embodiment 3:
Described in embodiment 1 or embodiment 2 for thering is the flue sampling apparatus of corrosive gas, described sampling pipe is arranged on described high-temperature flue by support 12, described sampling pipe stretches into the center of described high-temperature flue.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characterictic and is equal to the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to those skilled in the art's common practise.
