Technical field
This utility model relates to gas medium laser analysis technical field, particularly relates to a kind of laser gas analyzer light path
Protection device.
Background technology
Substantial amounts of CO, CO can be produced during bessemerizing2Deng gas medium, these media spray through a literary composition, two literary compositions
Be transported to one-time dedusting Ventilator Room through gas transmission pipeline after trickle rough dusting, after be transported to gas pressing through high pressure positive blower
Stand.Owing to needing to add the dispensing such as fluorite, Calx during bessemerizing, during adding these dispensings or due to blowing
Insufficient or the added Calx material bulk of chemical reaction is not enough, causes being produced under the suction of high-power blower
The media such as the CO come contain more solid particle polluter, still contain part solid after a literary composition, two literary composition dust removal process in medium
Body impurity, these media are again after the links such as dedusting fan impeller flushing water, and cause medium to be contained within substantial amounts of moisture, this
A little moisture are in a liquid state after mixing with solid particle polluter form existence, then under the effect of high pressure positive blower with gas medium together
Optical conduit through laser analyzer just has operative liquid impurity and flows to analyze along the optical conduit of laser analyzer
On the transmission lens of instrument, these impurity arrive after eyeglass under the air blast effect of blower fan blowing force can rapid contamination eyeglass and cause point
Analyzer transmitance reduces rapidly, and the reduction of transmitance can cause following adverse consequences:
1, maintainer need often analyser to be dismounted, the work such as wiping eyeglass, increase considerably labor intensity；
2, sometimes for the blowing gap in converter, equipment is keeped in repair, and medium has coal gas remaining, therefore exist relatively
Big carbon monoxide poisoning is dangerous；
3, the time interval between two smelting furnaces time is shorter, and the easy disassembling of analyser is upset rhythm of production；
4, in the concentration bessemerized and during Ventilator Room gas recovery, the reduction of transmitance can affect coal gas and oxygen,
Then the yield of coal gas is affected；
5, in the converting process of a heat, arise that the pass blocking of twice more than causes the biggest fiber crops to attendant
Tired；
6, laser analyzer is the electronic machine of a kind of precision, and dismounting will necessarily the use of impact analysis instrument itself frequently
In the life-span, increase equipment cost.
Produce practical situation more than comprehensive, be necessary for meet the needs of production taking measures to meet laser analysis as far as possible
The cleanliness of instrument transmission lens, and the premise meeting eyeglass cleanliness is just to try to ensure that the impurity such as sewage can not enter into analysis
In the laser pipeline of instrument, also to guarantee the distance of itself and eyeglass for a small amount of partial impurities entering into channel interior, make two
Person separates.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Elaborate a lot of detail in the following description so that fully understanding this utility model, but this practicality is new
Type can also use other to be different from alternate manner described here to implement, and those skilled in the art can be without prejudice to this reality
Doing similar popularization in the case of novel intension, therefore this utility model is not limited by following public specific embodiment.
As shown in Figure 1-2, the utility model discloses a kind of laser gas analyzer optical path protecting device, including guard shield 3,
Being coaxially mounted to the optical conduit 5 inside guard shield 3 and the water-ring 1 being fixedly mounted in optical conduit 5, described guard shield 3 is one
