Abstract
This invention relates to one air multi-point sampling automatic test device, which comprises air polluted test device, at least one sampling head, pipe system and controller, wherein, each head is connected to each sample pipe of pipe system and the gas out end of system is connected to the gas in end of pollute test device; pipe system is set with bus pipe and at least one electrical valve; each sample pipe is connected to bus pipe through relative electrical valve; controller is connected to each electrical valve to control each valve switch.
Description
Technical field
The invention belongs to environmental monitoring and automatic detection range, be specifically related to a kind of device that the clean room cleanliness factor detects and various environment gasoloid detects, the air pollutant detects that is used for.
Background technology
Progress along with science and technology, monitoring for the clean room cleanliness factor is paid attention to by people day by day, monitoring for cleanliness factor need be measured the multiple spot in the clean room, and that the metering system of multiple spot mainly contains is following several: many air counter centralized monitoring system, multitube sampling monitoring system and mix three kinds of forms of centralized monitoring system.Wherein comparatively economic mode is a multitube sampling monitoring system, and what this method adopted is that a big flow corpuscular counter links to each other with many flexible pipes.Change the mode of measuring point successively, a corpuscular counter is responsible for the monitoring of some points, and a plurality of sampling heads link to each other with a corpuscular counter with the multitube sampling thief by prolonging pipe.The multitube sampling thief can make each sampling head be connected with counter in turn under the control of controller, thereby each measuring point is carried out circulating sampling.
The Related product of at present existing multipoint mode sampling monitoring system, but generally all adopt rotary-type, promptly, many outer pipelines connect with pipe interface on the runner, by inner branch pipe of runner and the purpose of switching connection realization multipath conversion respectively that is connected house steward, this mode can realize the continuous conversion of pipeline, for the switching of great-jump-forward, because runner rotates the carrying out of necessary order, then switch comparatively inconvenience.And the bioaerosol sampling thief that prior art adopts can only be measured single measuring point, can not be simultaneously to multimetering.
Rotary-type in addition multi-point sampling device cost is also higher, and need buy with the counter binding.Counter of having purchased or the counter of not supporting multi-point sampling originally can't be utilized, then multi-point sampling can not be carried out.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, the multitube sampling and monitoring device that a kind of cost is lower, can carry out the multichannel redirect easily is provided, can be used with pollutant testing apparatus in the multiple air.
A kind of automatic recycling testing apparatus of air multiple-point sampling, comprise pollutant testing apparatus in the air, at least one sampling head, pipe system and controller, each sampling head links to each other with each road sampling pipe of pipe system respectively, and the port of giving vent to anger of pipe system links to each other with the air inlet port of pollutant testing apparatus in the air, it is characterized in that, described pipe system is provided with main pipe rail and at least one electrically operated valve that has the described port of giving vent to anger, and each road sampling pipe is connected respectively to main pipe rail by corresponding electrically operated valve; Controller links to each other respectively with each motorized valve, controls the open and close of each motorized valve.
Automatic recycling testing apparatus of the present invention preferably also comprises the air pump between the pollutant testing apparatus air inlet port in give vent to anger port and the air that is arranged on described main pipe rail.
Automatic recycling testing apparatus of the present invention preferably also comprises from cleaning device, links to each other with main pipe rail by electrically operated valve from cleaning device.
Pollutant testing apparatus can be a kind of in corpuscular counter, bio-aerosol particles checkout equipment, sulphuric dioxide detector, nitrogen dioxide detector, carbonmonoxide detector, carbon dioxide detector, ammonia detector, ozone analyzer, methylene oxide detecting instrument, benzene detector, toluene detector, benzo (a) pyrene pick-up unit, total volatile organism detection system or the radon detector etc. in the air of the present invention.
Automatic recycling testing apparatus of air multiple-point sampling of the present invention has following outstanding advantage:
1. existing multi-point sampling system adopts rotary-type, and the present invention adopts valve-type, can be under the control of controller, and the opening and closing motorized valve reaches the quick switching between the multi-channel sampling easily, improves the dirigibility of operation and stability, accuracy.
2. employing the present invention needn't be equipped with special-purpose corpuscular counter, have simple in structure, the advantage that cost is lower.
3. the present invention also can be used for other gas sampling, as can be used for Anderson sampling of multiple spot etc., reaches a tractor serves several purposes, has economy.
4. controller sampling process of the present invention and particle sampling apparatus coupling are good, and the particle diameter loss is little, durable in use.

Embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
Automatic recycling testing apparatus of air multiple-point sampling structural representation of the present invention is as shown in Figure 1: this automatic recycling testing apparatus of air multiple-point sampling mainly is made up of four parts: a plurality of sampling heads 1, controller 4, pipe system 3, corpuscular counter 5.Sampling head 1 is distributed in the clean room 6, by sampling pipe 2 each sampling head 1 is connected to a house steward by pipe system 3, realizes connecting with counter 5 again, and the main effect of controller 4 is motorized valves in the pilot piping system 3.
During use, earlier controller 4 and pipe system 3 being connected, mainly is that the control line with motorized valve 7 is connected with the interface of controller 4 back; The port of giving vent to anger with pipe system 3 links to each other with the air intake opening of pollutant testing apparatus 5 in the air again; At last each sampling pipe 2 is arranged into sampling head 1.What pollutant testing apparatus 5 adopted in the present embodiment in the air is corpuscular counter, in other embodiments, also can adopt the bio-aerosol particles checkout equipment, or other are used for monitoring the device of air all contaminations, as various borne bacteria samplers such as Anderson sampling thief, gas componant detector, the sulphuric dioxide detector, the nitrogen dioxide detector, carbonmonoxide detector, the carbon dioxide detector, the ammonia detector, ozone analyzer, methylene oxide detecting instrument, the benzene detector, the toluene detector, benzo (a) pyrene pick-up unit, the total volatile organism detection system, radon detector etc.
4 li designs of controller have control circuit, can realize motorized valve 7 the Automatic Cycle On/Off and manually opened/close.When using automatic control mode, " manual " control knob must be transferred to " automatically " shelves, can be by the button that is provided with of automatic control zone, cycle index is set, sampling time, interval time, parameters such as circulation line and unit, harmonious with pollutant testing apparatus in the air 5, finish multiple spot and test automatically.When using manual mode, " manual " button must be transferred to " manually " shelves, can switch the state of any pipeline by 9 manual control buttons.
Recycling testing apparatus of the present invention, when sample lines is longer, because the system pipeline resistance is bigger, sometimes pollutant testing apparatus 5 flows are difficult to reach in the air, preferably between the pollutant testing apparatus 5 air inlet ports auxiliary air pump are being installed in give vent to anger port and the air at described main pipe rail 8 again.
