In the use procedure of azotometer digestion instrument, poison gas is covered with the effect of extracting waste gas out.The principle cleared up be in kjeldahl flask (digest tube) under the condition of catalyst (copper sulphate, potassium sulfate) and high temperature, clear up sample with the concentrated sulfuric acid and organic nitrogen be all transformed into required inorganic ammonium salt.But in digestion process, the concentrated sulfuric acid plays the effect of dehydration and carbonization, a large amount of steam can be produced, carbon dioxide, carbon monoxide, harmful mist such as sulfur dioxide, existing method places funnel at kjeldahl flask bottleneck, allow waste gas directly be discharged in air, this method one pollutes the environment, and two is can work the mischief to user of service.Therefore be badly in need of a kind of can the device of safety dumping waste gas.
Summary of the invention
In order to solve the problem, the invention provides a kind of can the digesting equipment discharging waste gas device and method of safety dumping waste gas.
A kind of digesting equipment discharging waste gas device in the present invention, comprises the digest tube for the splendid attire concentrated sulfuric acid and sample, also comprises
Blast pipe, is used for toxic and harmful to discharge;
Connection rubber tube, aspiration pump, the toxic and harmful that blast pipe is discharged enters aspiration pump through connection rubber tube;
Water inlet, air inlet, delivery line, described blast pipe is provided with several projection, and described projection stretches in digest tube, and described blast pipe one end connects air inlet, the other end is connected with aspiration pump by connection rubber tube, and described water inlet is connected with aspiration pump upper end, and the lower end of described aspiration pump connects delivery line.Air inlet, prevents generation vacuum of always bleeding, and extracts sample or sulfuric acid in digest tube out.
In such scheme, also comprise sealing ring, described sealing ring to be set in projection and to stretch into digest tube inside, is used for the projection of digest tube and blast pipe to seal.
In such scheme, also comprise poison gas cover, described poison gas cover covers on blast pipe, is used for preventing toxic and harmful from leaking.
In such scheme, also comprise poison gas cover and put dish, described poison gas cover is put dish and is used for putting poison gas cover and blast pipe.
In such scheme, also comprise digesting support, described digest tube is erected on digesting support.
In such scheme, also comprise cooling frame, described digesting support is erected on cooling frame, described cooling frame be used for nature cooling digest tube.
In such scheme, also comprise spring, described digesting support is connected by spring with sealing ring, and described spring is for adjusting the height of each digest tube.
A method for discharging waste gas, water flows into aspiration pump, and produce negative pressure, by the toxic and harmful in blast pipe through connection rubber tube suction aspiration pump, toxic and harmful is with water device for transferring.
Advantage of the present invention and beneficial effect are: the invention provides a kind of can the digesting equipment discharging waste gas device and method of safety dumping waste gas.Hermetic poison gas cover makes waste gas leak, and avoids the danger of user of service; Waste gas flows into sewer by running water in the condensation of body of heater side or absorption, would not can not corrode digestion instrument body; Sealing ring has the effect of blocking, if temperature is too high, sulfuric acid can climb up along digest tube tube wall, has sealing ring to block to mouth of pipe place, namely can go down by condensing reflux, plays the effect of washing away sample.
