The utility model discloses a split type structure has avoided causing the transportation impact force big and damage the shortcoming of circuit and accurate measurement part, and adopt split type structure, and the equipment is nimble, can make up wantonly, and the transport is convenient.
Description
Technical field
The utility model belongs to Analysis on Environment Contamination and monitoring field, relates generally to the sampling analysis of dioxin in the sampling analysis of target contaminant in flue, particularly flue gas and Dust and monitors a kind of portable sampling device used.
Background technology
In order to control and reduce air pollution emission, the stationary pollution sources such as industrial furnace such as the burning to municipal refuse, danger wastes burning, thermal power plant, steel mill are often needed to sample and monitor.General sampled point overhead has certain distance, brings inconvenience to sampling work.Existing portable flue gas sampling instrument adopts integral structure, all air path elements and forceful electric power and light current element are all arranged in a casing, not only seem in the process of carrying and transport too heavy, easily impact failure is subject in transportation, and forceful electric power and light current are put together, be difficult to avoid forceful electric power element to disturb weak electric signal in operational process, thus affect the parameter of sampled acquisition, finally cause sampled result inaccurate.Therefore the utility model proposes a kind of structure of new portable flue gas sampling instrument, namely split type flue gas sampling instrument, solves the series of problems that said structure brings to sampling work.
Utility model content
The technical matters that the utility model solves is to provide a kind of convenient Portable sampling instrument moving and transport.This split type flue gas sampling instrument, primarily of the filtrator for filtering removal solid particle thing, flow measurement cell, controller, display and input block, printer, vacuum pump, circuit connecting wire, gas circuit connecting pipe composition; Controller is connected with input block, printer with flow measurement cell, display respectively by wire; Controller is connected with vacuum pump by circuit connecting wire; The air intake opening of filtrator to export with sampling gun through capture unit and is connected, and the gas after the filtration that the gas outlet of filtrator is flowed out enters flow measurement cell, is connected to vacuum pump, then enters air through gas circuit connecting pipe.
Complete machine structure is divided into main and auxiliaries two parts, and main frame comprises filtrator, flow measurement cell, controller, display and input block, printer; Subsidiary engine comprises vacuum pump; Main and auxiliaries is arranged side by side or superpose placement.
Be the container that an inside is provided with filter membrane or filler for filtering the filtrator removing solid particle thing; Flow measurement cell is gas meter; Controller is single-chip microcomputer; Display and input block are the liquid crystal display of touch-screen or band physical button;
Circuit connecting wire is the cables of two ends with quick change terminal, after coordinating with the circuit interface on main and auxiliaries panel respectively, and delivered current and control signal.
Gas circuit connecting pipe is the pipelines of two ends with quick change gas path joint, after coordinating respectively, makes the pipeline connection between main and auxiliaries and keeps impermeability with the air-path interface on main and auxiliaries panel.
Capture unit comprises the flying dust trapping cylinder and sample capturing device of contacting successively, and sample capturing device is the container that inside is filled with the both ends open of resin extender.
The invention has the beneficial effects as follows: compared with the sampling instrument of traditional integral structure, integrated sampling instrument bottom vacuum pump moiety by weight is large and upper part is electric and the large weight of metering section volume is little, gravity centre distribution is uneven, adopts split-type structural to avoid and causes transportation impulsive force to damage greatly the shortcoming of circuit and delicate metering parts; And employing split-type structural, assembling flexibly, can combination in any, convenient in carrying.
