Abstract
The utility model is related to a kind of online reconstruction structures for searching the furnace radiating pipe breakage of non-oxidation continuous heat, diversion pipe is installed on the furnace wall of continuous oven both sides, the diversion pipe inner end is stretched into stove, first flange is provided on diversion pipe, the diversion pipe outer end is connected with sampling joint, sampling joint is docked for connecting oxygen analyzer between sampling joint and diversion pipe by second flange；Under non-detection status, flange closure.The on-line quick detection to revealing oxygen site in heat-treatment furnace is realized, without blowing out, safe ready helps to save the energy consumption caused by blowing out stops production.
Description
Technical field
The utility model is related to heat-treatment furnace equipment, change especially for the structure of heat treatment furnace radiant tube damage testing
It makes.
Background technology
In quantity-produced non-oxidation heat processing furnace, once there is radiant tube burn-through, then in the flue gas that burner sprays
Oxygen by leak source can flow into burner hearth with flue gas, at this point, the online oxygen analyzer of heat-treatment furnace can detect residual oxygen, but at heat
The residual oxygen analytical instrument of reason stove can only reflect whether burner hearth has residual oxygen, but cannot quickly position residual oxygen and appear in which branch of which region is burnt
Mouth, scene are a very cumbersome process to residual oxygen finding leak source or even blowing out are needed to be carried out after stopping production.And blowing out not only shadow
Production is rung, and a large amount of manpower and materials and the fuel consumption of heat-treatment furnace heating and cooling can be wasted, in the heat of continuous use for many years
In treatment furnace, radiant tube burn-through is a kind of relatively common failure, the radiant tube of burn-through how is rapidly found out, by the radiant tube
Burner is closed, and oxygen leakage is prevented then to be particularly important.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of non-oxidation heat processing furnace for the above-mentioned prior art
Structure of modification, be easy to implement and online search radiant tube damage location.
The technical scheme in the invention for solving the above technical problem is：A kind of online lookup non-oxidation continuous heat
The reconstruction structure of furnace radiating pipe breakage is equipped with diversion pipe on the furnace wall of continuous oven both sides, and the diversion pipe inner end is stretched into stove,
First flange is provided on diversion pipe, the diversion pipe outer end is connected with sampling joint, and sampling joint is used to connect oxygen analyzer,
It is docked between sampling joint and diversion pipe by flange；Under non-detection status, flange closure.
Preferably, it is provided with sampling shut-off valve on the inside of the sampling joint.
Compared with prior art, the utility model has the advantage of：A kind of reconstruction structure of continuous heat treating furnace is provided,
For the thermal insulation layer of continuous oven, the floss hole at heat treatment furnace body both ends increases fixed measuring point and complete installation sampling probe.
In the case of thus may be implemented in not blowing out, manual analyzing is carried out using portable micro oxygen analyzer.
Description of the drawings
Fig. 1 is the reconstruction structure schematic diagram of heat-treatment furnace in the utility model embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing embodiment.
As shown in Figure 1, the online reconstruction structure for searching the furnace radiating pipe breakage of non-oxidation continuous heat in the present embodiment,
Diversion pipe 1 is installed on the furnace wall of continuous oven both sides, the diversion pipe inner end is stretched into stove, and the first method is provided on diversion pipe 1
Orchid 2,1 outer end of diversion pipe are connected with sampling joint 3, and sampling joint 2 is provided on the inside of sampling joint and takes for connecting oxygen analyzer
Sample shut-off valve 5 is docked between sampling joint 3 and diversion pipe 1 by second flange 4.Under non-detection status, first, second flange
Closing.
The Heat Treatment Furnace Reformation structure of above structure realizes the online quick inspection to revealing oxygen site in heat-treatment furnace
It surveys, without blowing out, safe ready helps to save the energy consumption caused by blowing out stops production.
Sample gas analyzes basic principle：(sampling probe can via the taking-up of the sampling probe of installation and field pipes for sample gas
For on-line analysis and manual analyzing), enter analysis system cabinet through sample transfer pipeline, be negative pressure for process sample, it will be by
It analyzes sampling pump in cabinet and sample transfer power is provided.The sample gas being removed cools down in analysis cabinet by by-pass filtration, level-one,
Two level cools down, and removes moisture and analyzed via accurate filter feeding analyzer.
In addition to the implementation, the utility model has further included other embodiment, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection domain of the utility model claims.
Claims (2)
1. a kind of online reconstruction structure for searching the furnace radiating pipe breakage of non-oxidation continuous heat, it is characterised in that：In continuous oven
