Description

Malleation ash discharge dust arrester
The utility model relates to a kind of malleation ash discharge dust arrester that is used for infrared carbon sulfur analyzer.
The infrared carbon sulfur analyzer operation principle is to burn under high-frequency induction heating by sample to generate CO 2, SO 2Gas behind the dirt, enters the infrared Absorption analysis cell after filtration, is received by sensor then, absorbs characteristic wavelength light radiation variable quantity by measurement gas, is converted into the corresponding signal of telecommunication again, and inverting is the percentage composition of sample.In combustion process, except carbon, element sulphur and oxygen chemical combination generate CO 2, SO 2Outside the gas, other materials of while such as the corresponding generation oxide powder dust of metals such as iron, copper, if not with dust-filtering, dust can seriously stain pipeline and analysis cell so, its harmfulness is as follows:
(1) after the dust in the gas stains air chamber, reduce the light transmittance of optical window and the reflective character of tube wall, the optics that reduces light path transfers efficient, causes instrumental sensitivity to descend, even makes the Instrumental Analysis pond entirely ineffective.
(2) after tube wall had adsorbed dust in pipeline and the analysis cell, these dust were to CO 2, SO 2Gas produces absorption and release effects, can produce absorption and reduce the content of tested gas in the gas when analyzing the high-load sample, and when measuring low content, the dust that has adsorbed discharges CO again 2, SO 2Gas increases the concentration of tested gas like this, so can introduce the dust absorption random disturbances of tube wall when analytic sample, has a strong impact on the precision and the correctness of sample analysis.
(3) dust can produce absorption, water and SO to aqueous vapor 2Generating sulfurous acid has increased SO 2Measure influence.
In the infrared carbon sulfur analyzer that various countries produce, in sample combustion burner device, all designed the dust filtration device of a stainless steel metal screen pack for this reason.But in the screen pack tube wall, adsorbed a large amount of dust in each the analysis, though these dust stain tube wall or analysis cell never again, but burning generates the dust major part and is deposited on the inwall of screen pack, dust on the screen pack, can produce adsorption effect equally, thereby the random disturbances of same generation adsorbed gas when analytic sample, while is because of the deposition of a large amount of dust, increased the vapour lock of screen pack, make and analyze throughput and reduce and cause analyzing data error and constantly increase, in order to overcome this problem, the analyst must not carry out artificial dedusting cleaning analyzing after 20 times in the past.But can not guarantee that analyzing internal state at 20 times finishes unanimity, understands the impact analysis precision equally.In recent years in order to address this problem, factory has increased a device of cleaning negative pressure ash discharge automatically in improving design, because of having increased a high power vacuum cleaner device in the negative pressure ash discharge, fall crucible tray during dedusting earlier, again gas circuit is sealed with the subiculum lid again, and then driving the dust removal brush dedusting with motor, the negative pressure by dust catcher produces goes out burner to dust clearly.The control in dust removal process of this device is complicated, has increased the dust discharge time.And because the high power vacuum cleaner noise is big, the user uses inconvenience, and most of user is reluctant to use this device.
The purpose of this utility model is to provide a kind of infrared carbon sulfur analyzer malleation ash discharge dust arrester that is used for.
The utility model malleation ash discharge dust arrester comprises combustion component, filter element, stop valve, disposal box and tube connector.Analytical gas leads to filter element by combustion component and enters analysis cell then through filter screen elimination dust.The dust on the drive link driven wheel brush removing filter screen in the filter element under microcomputer control, dust is connected to stop valve through ash releasing tube, is disposed to disposal box by barotropic gas.In addition, microcomputer control combustion component drive link driven wheel brush brushes quartz ampoule inwall splash in stroke range, and dust is disposed to disposal box through stop valve by barotropic gas by the quartz ampoule other end.The utility model is divided into disome to cleaning and filtering net and cleaning quartz ampoule, and adopts power gas to promote piston, drives stainless steel wheel brush separately, carries out screen pack dedusting and quartz ampoule respectively and cleans, i.e. this device dedusting and cleaning can be carried out step by step.Pneumatic dust collection speed is fast, can be after each analysis finishes, finish the screen pack dedusting by microcomputer control in one second, and carry out pulse enable by the stop valve of the ash releasing tube of pneumatic control, by pulse discharging barotropic gas, the screen pack inwall is cleaned the dust that gets off, take burner out of, realize the function of autobarotropy ash discharge cleaning by gas pulses.
