Abstract
The utility model relates to a device for purifying harmful gases, which is particularly to suitable for a Kjeldahl bottle. The utility model is composed of a sealing cover, a buffering bottle and an absorption bottle which comprises absorption liquid, wherein the sealing cover can be matched with an azotification bottle, and a conduit is arranged on the sealing cover. Gas inlet pipes and exhaust pipes are arranged on the buffering bottle and the absorption bottle. A shower head is arranged at the outlet of the gas inlet pipe of the absorption bottle, so exhaust gas can uniformly enter the absorption liquid and be fully absorbed. When a plurality of azotification bottles work simultaneously, a collecting pipe with a plurality of joints can be arranged in front of the buffering bottle to improve the availability ratio of an absorption system. The utility model has the advantages of simple structure and convenient use; the exhaust gas processed by the utility model can not pollute environment.
Description
The utility model relates to and a kind of pernicious gas is carried out the device of purified treatment, is specially adapted to the kjeldahl determination bottle.
Utilize Kjeldahl to measure contained protein in the plant, its digestion process is that plant sample is placed nitrogen fixing bottle, and adds reagent such as an amount of sulfuric acid, catalyst, adds thermal response then.Because nitrogen fixing bottle is uncovered bottle, the sulfur dioxide SO that its course of reaction produces
2, pernicious gas such as sulfur trioxide constantly emits from bottle, contaminated environment, the corrosion instrument influences health.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of can matching with nitrogen fixing bottle that pernicious gas is carried out the purified waste gas treating apparatus.
Technical solution of the present utility model is: the seal cover that can match with nitrogen fixing bottle is provided with conduit, it is with interior Sheng absorption liquid and have air inlet pipe and the absorption bottle of blast pipe communicates, absorption bottle can be one, also can be a plurality of mutual serial connections, forms multistage absorption treatment system.Between conduit and absorption bottle, be serially connected with surge flask.Send into absorption bottle by the pernicious gas that nitrogen fixing bottle is discharged through surge flask, to weaken the impulsive force of gas.For the gas that enters in the absorption liquid can fully be absorbed, be provided with the porous shower nozzle in the exit of absorption bottle air inlet pipe, it is divided into tiny air-flow with gas and enters absorption liquid equably.Be provided with and its connection and collecting pipe that have a plurality of interfaces that can seal or can be connected with conduit before surge flask or absorption bottle, its interface can be connected with the conduit on each seal cover.When a plurality of nitrogen fixing bottles are worked simultaneously, can handle by sending into absorption system behind the gas sampling of collecting pipe with each nitrogen fixing bottle generation.Improve the utilization rate of absorption system.The place also can connect exhaust pump at final stage absorption bottle gas exhaust outlet.
The utility model provides a kind of can cooperate the device that pernicious gas is carried out purified treatment with nitrogen fixing bottle, it is simple in structure, easy to use.After discharging, the gas of its purification do not pollute the environment and etching apparatus and influence health.This device also can match with other small test equipment and carry out exhaust-gas treatment, and can become the component selections absorption liquid according to pernicious gas.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the floor map of another embodiment of the utility model.
Be described in further detail below in conjunction with accompanying drawing:
As Fig. 1, decide the nitrogen emission-control equipment and form by seal cover (2), surge flask (3) and two absorption bottle (4), (5) that are connected in series mutually of carrying pipe (1).Surge flask and absorption bottle are the vial that has seal cover, are equipped with air inlet pipe (6) and blast pipe (7) on the seal cover.The effective flexible pipe of the inlet and outlet of advancing (8) of each bottle is connected.Adopt this structure to make whole system connection, convenient disassembly.Containing absorption liquid in the absorption bottle is alkali lye, can adopt useless NaOH.Be provided with porous shower nozzle (9) in absorption bottle air inlet pipe exit, it is positioned at alkali lye.During use, the seal cover that will have conduit is that grournd glass covers on nitrogen fixing bottle, makes its bottleneck sealing.The waste gas that produces in the bottle in the digestion process is drawn by conduit, sends into behind surge flask in the I and II absorption bottle, and in absorption bottle, toxic and harmfuls such as the acid mist in the waste gas, sulfur dioxide are absorbed by alkali lye, generates sulfate.Waste gas through purified treatment is discharged by final stage absorption bottle blast pipe.
As shown in Figure 2, when a plurality of nitrogen fixing bottles of needs are worked simultaneously, can connect a collecting pipe (10) with a plurality of interfaces on the surge flask air inlet pipe, its interface can be connected with the conduit on being connected each nitrogen fixing bottle, and the residue interface seals with sealing-plug.The waste gas that each nitrogen fixing bottle produces can enter collecting pipe by conduit separately, and sends into surge flask simultaneously and absorption bottle carries out purified treatment.Waste gas after the purification is discharged by final stage absorption bottle blast pipe.
Claims (5)
1, a kind ofly decides the nitrogen emission-control equipment, comprise nitrogen fixing bottle, it is characterized in that the seal cover that can match with nitrogen fixing bottle is provided with conduit, it is with interior Sheng absorption liquid and have air inlet pipe and the absorption bottle of blast pipe is connected, absorption bottle can be one, also can be a plurality of mutual serial connections.
2, according to claim 1ly decide the nitrogen emission-control equipment, it is characterized in that between conduit and absorption bottle, being serially connected with surge flask.
3, according to claim 1ly decide the nitrogen emission-control equipment, it is characterized in that the exit of absorption bottle air inlet pipe is provided with the porous shower nozzle.
