Description

Special gas sampler before Industrial Stoves dedusting

Technical field

This utility model is related to gas preprocessing technical field, more particularly, to Industrial Stoves in Coal Chemical Industry petrochemical production process Special gas sampler before dedusting.

Background technology

In Industrial Stoves furnace gas, dust content is especially big, and temperature is high, and is rich in vapor, if according to traditional sampling Method, can lead to the blocking of sampling probe, and sample gas can not reach analyser, makes analysis of fumes lose meaning, because analytical data Inaccurate, thus leading to whole set process often parking maintenance, bring very big economic loss and potential safety hazard.Traditional sampling probe because For ash disposal unfavorable lead to easily block cause sampling failure effect analysis result.

Utility model content

The purpose of utility model：In order to provide special gas sampler before a kind of more preferable Industrial Stoves dedusting of effect, Specific purposes are shown in the multiple substantial technological effects being embodied as part.

In order to reach as above purpose, this utility model adopts the following technical scheme that：

Special gas sampler before Industrial Stoves dedusting, it is characterised in that comprising drive pipe, drive pipe wraps Containing the vertical static sedimentation chamber connecting, comprise a horizontal probe tube above static sedimentation chamber, drive pipe avris comprises one Individual high-temperature solenoid valve.

The further technical scheme of this utility model is, described static sedimentation intracavity portion comprises a filter, filter Gas can be filtered subsequently introduce gas in probe tube.

The further technical scheme of this utility model is, also comprises high temperature handss between described drive pipe and static sedimentation chamber Dynamic flanged ball valve.

The further technical scheme of this utility model is, comprises muff outside described static sedimentation chamber.

The further technical scheme of this utility model is, the side of described drive pipe is connected to air accumulator, described gas storage Nitrogen is stored in tank.

The further technical scheme of this utility model is, comprises the oral area of taper, gas storage in the pipeline of described drive pipe The position of tank and drive pipe docking also comprises the oral area of taper, comprises passage and lead to static sedimentation between the oral area of two tapers Chamber.

The further technical scheme of this utility model is, described filter is ceramic element or the rustless steel filter element of 40 μ.

Using this utility model of as above technical scheme, have the advantages that with respect to prior art：This utility model Using Venturi tube principle, when air-flow passes through to purge chamber, negative pressure can be formed in deposit cavity, thus producing one to blow a suction Air-flow environment, brings purging chamber into the dust of deposit cavity, is blown into pipeline together with purging air-flow, thus reaching the purpose of ash disposal.

Brief description

In order to further illustrate this utility model, it is further illustrated below in conjunction with the accompanying drawings：

Fig. 1 is utility model structural representation；

Wherein：1. sample pipe box；2. the manual flanged ball valve of high temperature；3. purge chamber；4. high-temperature solenoid valve；5. air accumulator；6. Probe tube；7. static sedimentation chamber；8. muff；9. filter.

Specific embodiment

Below in conjunction with the accompanying drawings embodiment of the present utility model is illustrated, embodiment is not constituted to limit of the present utility model System：

Special gas sampler before Industrial Stoves dedusting, it is characterised in that comprising drive pipe, drive pipe wraps Containing the vertical static sedimentation chamber connecting, comprise a horizontal probe tube above static sedimentation chamber, drive pipe avris comprises one Individual high-temperature solenoid valve.The technique effect of the essence that the technical scheme at this place is played and its process of realizing are as follows：This place is at least Enable ash fall, this device makes bulky grain dust first because gravitational settling in static sedimentation chamber.

Described static sedimentation intracavity portion comprises a filter, and filter can filter gas and subsequently introduces gas into and take In sample pipe.The technique effect of the essence that the technical scheme at this place is played and its process of realizing are as follows：Carried out using filter Secondary filter ash disposal.

The manual flanged ball valve of high temperature is also comprised between described drive pipe and static sedimentation chamber.Outside described static sedimentation chamber Comprise muff.The side of described drive pipe is connected to air accumulator, stores nitrogen in described air accumulator.Described drive pipe Pipeline in comprise the oral area of taper, the position of air accumulator and drive pipe docking also comprises the oral area of taper, two tapers Comprise passage between oral area and lead to static sedimentation chamber.The technique effect of the essence that the technical scheme at this place is played and its realized Journey is as follows：When ash reaches to a certain degree, opens solenoid valve carries out blowback ash and is inhaled into purging chamber in the situation of negative pressure, Together it is blown in pipeline together with purge gas, compared with traditional sampling probe, in the environment of high dust, energy is effectively for this device Ensure the continuous sampling of sample gas.It is purging chamber between the oral area of two tapers.Purging chamber is based on Venturi tube principle.

Preferably, described filter is ceramic element or the rustless steel filter element of 40 μ.

This patent can be under conditions of not affecting sample gas components, for the continuous sampling under high dust, high humidity environment.

Sample gas enters from pipeline and enters static deposit cavity behind sampling pipe box, manual ball valve, purging chamber during this device, Larger dust here, because gravity relationship, is deposited on bottom, less dust is filtered by ceramic filter, is deposited on filter Surface.When purging, air accumulator provides enough high-pressure air source to probe, can form negative pressure, filtration in deposit cavity The dust on device surface and the dust suction purging chamber being deposited on bottom, are blown in pipeline together with purge gass, reach dedusting Effect

The heating constant-temperature equipment of this device makes the temperature of sample gas be maintained at 120 degrees Celsius, so that the liquid water in sample gas It is gasified totally.

Blowback air is dry nitrogen.Filter is ceramic element or the rustless steel filter element of 40 μ.Air accumulator is 0.5 liter Above capacity.

In a creative way, each effect above is individually present moreover it is possible to complete the combination of the above results with a nested structure.

It is clear that the technique effect that above structure is realized is realized, and discounting for additional technical scheme, this patent title is also Can be a kind for the treatment of facilities.In figure not shown part details.

It should be noted that multiple schemes that this patent provides comprise the basic scheme of itself, separate, not mutually Restriction, but it can also be mutually combined in the case of not conflicting, and reach multiple effects and jointly realize.

Of the present utility model ultimate principle, principal character and of the present utility model advantage have been shown and described above.Ability The technical staff in domain it should be recognized that this utility model is not restricted to the described embodiments, described in above-described embodiment and description Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model also can There are various changes and modifications, these changes and improvements both fall within claimed scope.
