Abstract
The utility model provides anti-blocking air pressure sampling equipment and relates to sampling equipment used for measuring the negative pressure in a hearth in order to solve the problems that a sampling pipeline is blocked easily and hard to clean. The anti-blocking air pressure sampling equipment comprises a sampling device and further comprises a sampling pipe which is a T-pipe, the T-pipe is provided with one inlet and two outlets, the inlet of the sampling pipe is fixedly connected with the wall of the hearth, the first outlet of the sampling pipe is provided with a chock plug, and the second outlet of the sampling pipe is connected with the sampling device in a butt-welding mode. The anti-blocking air pressure sampling equipment is used for measuring the negative pressure in the hearth.
Description
Technical field
The utility model relates to for measuring the sampling equipment of combustion chamber draft, refers to especially a kind of Antichoking blast pressure sampling equipment.
Background technology
The Antichoking blast pressure sampler is according to the gas flow principle, is subject to stopping impact, makes to be contained in the impurity that its proportion in air is greater than air, and fine particle sinks, and the air upwards flowed out is purified, and avoids blocking pipe.The Purge gas obtained can be obtained correct measurement by draft gauge, so that reaches the purpose of Antichoking blast pressure sampling.
At present, the anti-blocking wind sampler pressure pipeline that power plant uses is longer, and there is bending to turn to, easily stop up, on-the-spot coal dust delivery pipe installation site decision pressure pipe and dust falling device are all installed in high-altitude, after obstruction, be not easy to safeguard, after the pressure line clogging, cause pressure normally not show, easily cause the operations staff to judge by accident disconnected, because erroneous judgement is disconnected, also caused tube cell to stop up long-pending coal ignition, damage tube cell (combustion chamber draft is regulated improper simultaneously), greatly increased repair and maintenance personnel's workload and labour intensity.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of Antichoking blast pressure sampling equipment, to solve that the pressure pipe Louis is stopped up and the problem of easy to clean not.
For solving the problems of the technologies described above, the utility model embodiment provides a kind of Antichoking blast pressure sampling equipment, comprise sampler, also comprise stopple coupon, described stopple coupon is three-way pipe, and described three-way pipe is provided with import two outlets, and the import of described stopple coupon is fixedly connected with hearth wall, the outlet one of described stopple coupon is provided with plug, and the outlet two of described stopple coupon is connected with described sampler butt welding.
Wherein, the axis of described stopple coupon and described hearth wall are 45 ° of angles.
Wherein, the axis of the vertical line of described sampler and described stopple coupon is 45° angle.
Wherein, the outlet one of described stopple coupon is equipped with the sealed copper pad.
Wherein, the material of described stopple coupon is stainless steel.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, effectively reduce the probability of occluding device in the sampling process, increased the accuracy of measuring; Increase plug and sealed copper pad, improved the sealing of stopple coupon, be convenient to cleaning after equipment stops up, adopt stainless steel, improved corrosion resistance, be convenient to install.

Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, the utility model stops up for existing pressure pipe Louis and the problem of easy to clean not, a kind of Antichoking blast pressure sampling equipment is provided, comprise sampler 4, it is characterized in that: also comprise stopple coupon 1, described stopple coupon 1 is three-way pipe, described three-way pipe is provided with import two outlets, the import 5 of described stopple coupon 1 is fixedly connected with hearth wall 2, and the outlet 1 of described stopple coupon 1 is provided with plug 3, and the outlet 27 of described stopple coupon 1 is connected with described sampler 4 butt welding.
Further, described stopple coupon 1 is the stainless steel three-way pipe, corrosion-resistant, and its internal diameter is 42 ㎜, and external diameter is 50 ㎜, and length is 750 ㎜; Described three-way pipe is provided with an import two, and the import 5 of described stopple coupon 1 is 45 ° of angles with hearth wall 2 and is fixedly connected with, convenient sampling, and dust is difficult for entering.
Wherein, the outlet 1 of described stopple coupon 1 is equipped with sealed copper pad and plug 3, strengthens sealing and prevents gas leakage, improves the accuracy of measuring, and when occurring to stop up, can open plug 3, and described stopple coupon 1 is cleared up, easy to operate.
Further, the outlet 27 of described stopple coupon 1 is 150 ㎜ with the distance of described outlet 1, described outlet 27 is welded with sampler 5, the axis of the vertical line of described sampler 5 and described stopple coupon 1 is 45 ° of angles, firm welding is without gas leakage, inner wall smooth, without welding slag, guarantees the accuracy that the rear negative pressure of sampling is measured.
In such scheme, effectively reduce the probability of occluding device in the sampling process, increased the accuracy of measuring; Increase plug and sealed copper pad, improved the sealing of stopple coupon, be convenient to cleaning after equipment stops up, adopt stainless steel, improved corrosion resistance, be convenient to install.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
