Abstract
The utility model relates to a smoke dust sampling pipe, and belongs to the field of environment-friendly monitoring devices. The smoke dust sampling pipe comprises a pipe body, wherein the pipe body comprises a sampling nozzle, a bent pipe and a filtering mechanism; the sampling nozzle is arranged on the front end of the pipe body; one end of the bent pipe is connected closely in back of the sampling nozzle; the other end of the bent pipe is connected with the filtering mechanism; the filtering mechanism comprises a filter cylinder placed in the pipe body, and a filter cylinder cover; one end of the filter cylinder cover is fixedly connected with the bent pipe; the other end of the filter cylinder cover is provided with a thread; the outer edge of an inlet of the filter cylinder closes to the outer edge of a pipe body at the outer side of the filter cylinder; and the pipe body at the outer wall of the filter cylinder is provided with a thread segment matched with the filter cylinder cover, and the outer side of the filtering mechanism is provided with a protective sleeve. The smoke dust sampling pipe provided by the utility model has the advantages that the structure is simple, and the operation is convenient; and the smoke dust sampling pipe is convenient to be externally connected with other equipment, so that the environment detection is realized.
Description
Technical field
The utility model relates to a kind of soot sampling tube, belongs to the environment monitoring apparatus field.
Background technology
At present, the environmental pollution that causes due to pollution source such as Industrial Boiler and Industrial Stoves is quite serious, this just need to detect the graininess dust concentration of its discharging, pollutant is carried out overall control and pollution control provides decision-making foundation, nowadays detection method commonly used has weight method, opacity method, charge method etc.Wherein weight method is now most popular, and ultimate principle is after the flue dust of certain volume passes through the clean filter cylinder of known weight, and the particle in flue dust according to filter cylinder weight difference and sampling volume before and after sampling, is calculated dust content by detention.And use sampling pipe in this method, in order to guarantee error can not occur in sampling, detecting data can reflect truth, just demands urgently a kind of simple in structurely, easy to operate, uses the soot sampling tube of safety.
The utility model content
The utility model is for the deficiencies in the prior art, and a kind of easy to use, safe, simple in structure, soot sampling tube that production cost is low is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of soot sampling tube, comprise body, it is characterized in that, described body comprises sampling mouth, bend pipe and filter mechanism, described sampling mouth is arranged on the front end of described body, immediately following an end of the described bend pipe of sampling mouth back connection, the other end of described bend pipe connects filter mechanism.
Further, described filter mechanism comprises filter cylinder and the filtering cartridge lid that is placed in body inside, one end of described filtering cartridge lid is fixedly connected with bend pipe, described filtering cartridge lid other end inboard is provided with screw thread, the outward flange of described filter cylinder porch is close to filter cylinder outboard tube external edge, and the body in the described filter cylinder outside is provided with the thread segment that matches with filtering cartridge lid.
Further, be provided with protective sleeve in the outside of described filter mechanism.Further the protection filter mechanism, avoid occurring flue dust and reveal.
The beneficial effects of the utility model are: the flow direction of mouth over against flue dust of sampling, flue dust is by sampling mouth and bend pipe, enter filter mechanism, by the filter cylinder in filter mechanism, particulate material detention in flue gas on filter cylinder, is then measured the weight of filter cylinder, can draw the weight of graininess goods and materials with the difference of clean filter cylinder weight before, in conjunction with can draw the content of particulate material in flue gas by the volume of flue dust, thereby cause environmental pollution that decision-making foundation is provided for judging whether.The utility model is simple in structure, and is easy to operate, convenient external miscellaneous equipment, thus realization is to the detection of environment.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In Fig. 1,1, the sampling mouth; 2, bend pipe; 3, filtering cartridge lid; 4, protective sleeve; 5, filter cylinder; 6, body.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
As shown in Figure 1, a kind of soot sampling tube comprises body 6, described body 6 comprises sampling mouth 1, bend pipe 2 and filter mechanism, described sampling mouth 1 is arranged on the front end of described body 6, and immediately following an end of the sampling mouth 1 described bend pipe 2 of back connection, the other end of described bend pipe 2 connects filter mechanism.
Described filter mechanism comprises filter cylinder 5 and the filtering cartridge lid 3 that is placed in body inside, one end of described filtering cartridge lid 3 is fixedly connected with bend pipe 2, described filtering cartridge lid 3 other end inboards are provided with screw thread, the outward flange of described filter cylinder 5 porch is close to filter cylinder outboard tube external edge, and the body in the described filter cylinder outside is provided with the thread segment that matches with filtering cartridge lid 3.
Be provided with protective sleeve 4 in the outside of described filter mechanism.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
