Description
Technical field
The present invention relates to a kind of sampling appliances of coke oven exhaust gas analysis technical field, more particularly to a kind of coke oven vertical flame path
Waste gas sampling device.
Background technique
Coke oven in process of production, to reach highest hot working efficiency, i.e., under the premise of guaranteeing that coke is mature, using most
The gas volume of small limit, makes every effort to the coking heat consumption for having minimum, needs persistently to carry out fire tuning operation to coke oven, and the combustion in flue
The ingredient for burning exhaust gas is a very important reference frame in fire tuning work.But since temperature is higher in flue, sampling compared with
For difficulty.Currently, exhaust sample generally uses steel pipe or stainless steel tube to protrude into sampling in coke oven vertical flame path, lacked there is following
It falls into:
1) about 0.5 meter of steel pipe, the exhaust sample of acquirement inadequate because protruding into the length in flue are used when early stage samples
It is not that burning generates, so that analysis is meaningless；
2) it is gradually sampled later using the enough seamless steel pipes of length or Heat-Resisting Stainless Steel Tube, but due in flue
Temperature is very high, and fractions react with seamless steel pipe or Heat-Resisting Stainless Steel Tube at high temperature in exhaust gas, therefore, causes point
Analyse data inaccuracy；
3) sampling between steel pipe or stainless steel tube and peephole seat has gap, has air to leak into flue in sampling process,
Influence the accuracy of sampling；
4) since the temperature in flue is very high (1000 DEG C or more), probe tube is generally disposable, without
Ji.
Summary of the invention
To overcome prior art defect, the technical problem to be solved by the present invention is to provide a kind of coke oven vertical flame path exhaust gas sampling dresses
It sets, can solve the problems, such as that impact analysis result is not allowed in coke oven vertical flame path exhaust gas sampling, have structure simple, lighter weight uses
It is convenient, it can repeatedly use, economical and practical feature.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
A kind of coke oven vertical flame path waste gas sampling device, including probe tube, seat board and sample connection, which is characterized in that described
Probe tube is hollow tube, and one end and sample connection are welded to connect；The seat board welding is arranged on probe tube away from the another of probe tube
The position that one end distance is L.
The probe tube material is quartz glass, and interior diameter is 10~12mm, and length L requirement, which is protruded into flue, is more than
Across the lower along 100~150mm of hole.
The seat board is the circular plate structure of quartz glass material, with a thickness of 5~8mm, outer diameter dimension and peephole
Lid matching, interior diameter is matched with the overall diameter of probe tube, and is welded together with probe tube.
The sample connection is the hollow tubular structure of quartz glass, and overall diameter is 6~8mm, and interior diameter is 4~6mm, length
For 45~55mm.
Compared with prior art, the beneficial effects of the present invention are:
1) quartz glass seat board outer diameter is identical as peephole lid, can combine closely between peephole seat, effectively anti-
Only air leaks into flue in measurement process, guarantees the accuracy of sampling result；
2) quartz glass probe tube pipe stable material quality will not occur anti-at a high temperature of flue with ingredient any in exhaust gas
It answers, it is ensured that the accuracy of sampling result；
3) quartz glass probe tube is protruded into flue and is taken more than the lower edge across hole into exhaust gas flow region
Exhaust gas is the exhaust gas that gas-fired generates, and sampling is accurate；
4) have structure simple, lighter weight is easy to use, can repeatedly use, economical and practical feature.
Detailed description of the invention
Fig. 1 is structural principle schematic front view of the invention；
Fig. 2 is structural principle diagrammatic top view of the invention.
In figure: 1- probe tube 2- seat board 3- sample connection
Specific embodiment
