Abstract
The invention discloses a constant-temperature multipath air and particle sampler. The constant-temperature multipath air and particle sampler comprises a cutter, a blower box and a main case. The main case is arranged on a frame. The cutter is connected to the blower box. The blower box is arranged on the frame. The constant-temperature multipath air and particle sampler also comprises an air exhaust part, a thermostatic part, a heating part and a particle sampler in the main case. The air exhaust part comprises singlechip control units, sucking pumps, solenoid valves and electronic flowmeters, and the sucking pump, the solenoid valve and the electronic flowmeter are electrically connected to the singlechip control unit. The constant-temperature multipath air and particle sampler can realize continuous switchable sampling and single path or double path simultaneous sampling, can be used in a low temperature area, has simple appearance, complete functions and light weight, is convenient for use and carrying, really realizes unattended operation and saves a lot of resources.
Description
Technical field
The present invention relates to a kind of air sampling instrument, be specifically related to a kind of constant-temperature multi-way air sampler and particle sampler, belong to environmental monitoring technology field.
Background technology
At present, in environment evaluation and test, for SO in ambient atmosphere
2the collection of oxides of nitrogen, national regulation SO
2sample temperature be 23-29 degree Celsius, the collecting temperature of oxides of nitrogen is 16-24 degree Celsius, when gathering in same constant temperature oven, it is constant between 23-24 degree Celsius that calorstat temperature is wanted, traditional constant temperature sampling thief mostly is the structure that main frame adds constant temperature oven, the sampling thief majority of this structure can only carry out single channel or two-way sampling, and gas circuit connects loaded down with trivial details, for the situation that much need to carry out atmosphere Discontinuous sampling (repeatedly sampling), use traditional constant temperature sampling thief sampling need to exchange frequently absorption bottle for, sometimes, also need to carry the sampling thief of particle, waste time and energy, in some low temp areas, cannot use, to use, cause very large trouble.
Summary of the invention
The deficiency existing for prior art, technical matters to be solved by this invention is, provides a kind of without frequently exchanging absorption bottle for, can carry out easily atmosphere Discontinuous sampling, can quick fetching absorption bottle.Improve the dirigibility of sampling precision and use, can use in low temp area, guarantee the validity of sampling, improve practicality, saved constant-temperature multi-way air sampler and the particle sampler of human and material resources.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of constant temperature multichannel atmosphere and particle sampler, comprise cutter, air box and be located at the mainframe box in frame, described cutter is connected with air box, air box is located in frame, also comprise bleed part, constant temperature part, heating part and the particle sampler be located in mainframe box, described in the part of bleeding by Single-chip Controlling unit and the aspiration pump, solenoid valve and the electronic flow-meter that all electrically connect with Single-chip Controlling unit, formed.
Above-mentioned constant temperature multichannel atmosphere and particle sampler, described constant temperature part is by temperature control unit and how logical constant temperature oven forms, and described many logical constant temperature ovens electrically connect by temperature control unit and Single-chip Controlling unit.
Above-mentioned constant temperature multichannel atmosphere and particle sampler, described many logical constant temperature ovens are connected with surge flask by electronic flow-meter.
The advantage of constant temperature multichannel atmosphere of the present invention and particle sampler is: integrated particle sampler (TSP, PM2.5, PM10 etc.), this sampling thief, without frequently exchanging absorption bottle for, can carry out atmosphere Discontinuous sampling easily, adopt integral type to absorb bottle stand, can quick fetching absorption bottle.Absorption bottle, directly to atmosphere, has improved sampling precision, also can pass through sampling pipe, has improved the dirigibility of using.Automatic-heating during lower than 5 ℃, can be used in low temp area, guarantees the validity of sampling, has improved practicality, has saved human and material resources.Not only can realize continuous switch sampling but also can realize single channel or the two-way multiple sampling pattern such as simultaneously sample, and can use in low temp area, outward appearance is succinct, and telotism is lightweight, uses easy to carryly, has really realized unmanned, has saved ample resources.
Accompanying drawing explanation

Fig. 2 is the inner structure schematic diagram of mainframe box.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further details;
As shown in Figure 1, 2, a kind of constant temperature multichannel atmosphere and particle sampler, comprise cutter 1, air box 2 and be located at the mainframe box 4 in frame 3, cutter 1 is connected with air box 2, air box 2 is located in frame 3, also comprise bleed part, constant temperature part, heating part and the particle sampler be located in mainframe box 4, the part of bleeding is comprised of Single-chip Controlling unit 5 and the aspiration pump 6, solenoid valve 7 and the electronic flow-meter 8 that all electrically connect with Single-chip Controlling unit 5.Constant temperature part is by temperature control unit 9 and how logical constant temperature oven 10 forms, and how logical constant temperature oven 10 electrically connects by temperature control unit 9 and Single-chip Controlling unit 5.Many logical constant temperature ovens 10 are connected with surge flask 11 by electronic flow-meter 8, are serially connected with in gas circuit, make layout more succinct, and it is more accurate to measure.
The present invention by bleeding, the part such as constant temperature, heating and particle sampler is organically combined into one, the part of bleeding is mainly comprised of solenoid valve 7, electronic flow-meter 8, aspiration pump 6 etc.Constant temperature part is comprised of absorption bottle, temperature conditioning unit.Heating part is comprised of absorption bottle, heating plate, temperature control etc.Particle sampler is comprised of cutter 1, blower fan, controller etc., can install additional according to actual needs, and independent operating, does not interfere with each other.
During sampling, absorption bottle is accessed in the middle of gas circuit (while using particle sampler, carry additionally particle sampler, and connect gas circuit, control circuit), set pattern, the thermostat temperature of sampling, main frame internal electrical magnet valve is received respectively absorption bottle in constant temperature oven by pipeline, thereby controls by the Single-chip Controlling unit 5 of mainframe box 4 inside the effect that solenoid valve 7 break-makes realize continuous sampling.Many logical constant temperature ovens 10 inside guarantee that by temperature control unit 9 many logical interior temperature of constant temperature oven 10 remain on arbitrary value between 10--30 degree Celsius.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
