With one quartz burner of each device in lower end, cleaning position inside middle-end two photocatalytic titania films of parallel device.
The lower end device water inlet pipe in circulating cooling layer left side, the lower end device outlet pipe in circulating cooling layer right side.
The escape pipe right-hand member passes circulating cooling layer right side upper end, escape pipe right-hand unit air outlet valve.
The probe tube right-hand member passes circulating cooling layer right side middle-end, probe tube right-hand unit sampling valve.
End device compression pump in the outlet pipe.
Advantage of the present utility model：A kind of nitrogen oxides of exhaust gas purifier of the present utility model, using PP cottons filter screen,
Active carbon filter screen, dust cloth bag carry out filtration treatment to waste gas, flue dust, bulky grain thing and part that can rapidly in eliminating waste gas
Sulfur dioxide；Secondly, purified treatment is carried out to waste gas using photocatalytic titania film, photocatalytic titania film is in ultraviolet
Under the irradiation catalytic action of lamp, the nitrogen oxides in waste gas can be purified rapidly, and photocatalytic titania film has nontoxic, catalysis
It is active high, easily prepare, cost is low, many advantages, such as stablized, and drastically increases clean-up effect, and saved and be cleaned into
This, using very convenient；In addition, being provided with circulating cooling layer, while purification, EGT is rapidly reduced；In addition, also setting
Probe tube is equipped with, is easy to be sampled detection to the waste gas after purification, it is ensured that the clean-up effect of waste gas.
