Description
Technical field
The present invention relates to electronic measuring technology field, specifically a kind of phosphine for tobacco storage and humiture three-dimensional real time method.
Background technology
At tobacco business, tobacco leaf is the most basic, most important raw materials for production.Because of tobacco business has certain singularity, promptly stock up in a large number after the warehouse standing storage by disposable as the tobacco leaf of raw materials for production.In this storage process, should carry out necessary desinsection and handle,, make the tobacco leaf must be before being used to produce through the natural alcoholization process of a long period again according to the requirement of characteristic and the production technology of tobacco leaf plant to tobacco leaf.In addition, also need store a large amount of semi-manufacture cigarette and finished cigarettes in the warehouse.Therefore, making that tobacco warehouse is a storehouse that stores raw materials for production and product, is again a workshop that raw materials for production are carried out handling early stage, and its storage capacity is bigger.
For the desinsection processing mode of tobacco leaf, mainly be to adopt phosphine gas to come tobacco leaf is fumigated as chemical fumigant.Because of phosphine gas has the characteristic of easy spontaneous combustion of excessive concentration or blast, so it is the major hidden danger of tobacco warehouse breaking out of fire.Phosphine gas is that phosphorization aluminium powder or tablet are spontaneous by absorbing water in air part.Therefore, ambient humidity is the key factor of decision phosphine gas concentration size in the injected volume of aluminum phosphate and the storehouse.Moreover phosphine gas proportion is greater than air, and its concentration is extremely uneven at warehouse internal upper part and middle and lower part spatial distributions.
Tobacco leaf also is strict for the requirement of ambient humidity in the warehouse in the natural alcoholization process.If humidity is too high, tobacco leaf occurs large-area variable color easily, goes bad, dashes and burn, go rotten and the phenomenon of damaging by worms, and its loss to tobacco leaf is huge; If humidity is low excessively, the percentage of raw brokens condition with higher then appears in tobacco leaf easily, and it can make the loss of tobacco leaf increase greatly.Therefore, whether ambient humidity suits directly to have influence on the quality of tobacco after standing storage in the storehouse, and the quality of tobacco leaf not only directly has influence on the quality and the quality of cigarette finished product, and has influenced the economic interests of tobacco business greatly.
In whole storage process to tobacco warehouse in the measurement of environment temperature, mainly consider from fire preventing hidden danger angle, it for operating personnel in time grasp, disposition, equally also be crucial.
At present, tobacco business is for this work, generally be phosphorization aluminium powder or the tablet of throwing in varying number by artificial diverse location in storehouse by rule of thumb, so the phosphine gas concentration size in the storehouse can't scientific quantification, if the too small insecticidal action that do not have of concentration is then caused danger easily if concentration is excessive.Measurement for temperature in the tobacco warehouse and humidity, also just adopt several traditional wet and dry bulb Hygrothermographs to be separately positioned in the warehouse in lower periphery position or the lower space, come mistake to be defined as temperature and humidity whole warehouse in by artificial regularly observed and recorded, for actual temperature in middle part and the upper space in the warehouse and then not consideration of humidity.Because of the storage capacity of tobacco warehouse bigger, the raw materials for production and the product that store are very many, and the dense degree of stacking and the height of heap all are bigger, if only measure lower periphery position or interior temperature and the humidity of lower space in the warehouse, next mistake is defined as temperature and the humidity in the whole warehouse, be not only very unscientific, and the consequence that it caused also is quite serious.
Moreover traditional wet and dry bulb Hygrothermograph is very backward because of its measurement means, and it often occurs can't showing owing to the wet bulb dehydration situation of humidity in use easily.It can only be to be used for environment temperature and not high family, the public place of humidity requirement are played the effect of a rough displays temperature and relative humidity, and it can not use in the tobacco warehouse very strict to environment temperature and humidity requirement at all.
For preventing the generation of fire, traditional fire alarm system of being made up of smoke detector system and spray system generally is installed in the tobacco warehouse at present, but its smoke detector system can only be discerned smog and can't discern colourless gas, and it is for the basic no any reaction of the height of phosphine gas concentration.If because of phosphorus gas hydrogen excessive concentration has produced smog after causing fire, just carry out work after smoke detector system and the spray system identification, this can only be the loss that reduces some fire, it can't play the effect of fundamentally avoiding fire to take place.Moreover the work of spray quinoline system also is very big to the loss of tobacco leaf.
In sum, how the storage capacity in the whole tobacco warehouse can be resolved into several stereo-unit spaces, and in each stereo-unit space, take three dimensional form that electronic measuring device is set, measure phosphine gas concentration, temperature and the humidity of upper, middle and lower portion in each stereo-unit space of tobacco warehouse in real time with three dimensional form, and receive to receiving trap by wireless transmit, guaranteeing that operating personnel in time grasp, handle correlation circumstance scientific quantification data accurately are provided, is a great problem that tobacco business is badly in need of solution.
Summary of the invention
The invention provides a kind of phosphine for tobacco storage and humiture three-dimensional real time method, it resolves into several stereo-unit spaces with the storage capacity in the whole tobacco warehouse, and in each stereo-unit space, take three dimensional form that a plurality of phosphine gas concentration measurement mechanisms and humiture measurement mechanism are set respectively, it can measure the phosphine gas concentration of upper, middle and lower portion in each stereo-unit space of tobacco warehouse with the three dimensional form real-time electronic, temperature and humidity, and receive to receiving trap by wireless transmit, so that being provided accurately in real time, the scientific quantification data in time grasp to operating personnel, the processing correlation circumstance uses; The measurement means that it can solve the prior art existence falls behind, and can't accurately measure phosphine gas concentration, temperature and the humidity of upper, middle and lower portion in each space of tobacco warehouse in real time, and can't guarantee the safety of standing storage tobacco leaf in the tobacco warehouse and the problem of quality.
The objective of the invention is to be achieved through the following technical solutions: phosphine for tobacco storage and humiture three-dimensional real time method, at first the storage capacity in the whole tobacco warehouse is resolved into several stereo-unit spaces, the tobacco leaf buttress that then each is had certain volume places respectively in each stereo-unit space one by one, in each stereo-unit space, take three dimensional form that several phosphine gas concentration measurement mechanism and humiture measurement mechanisms are set respectively, measure the phosphine gas concentration in each stereo-unit space in the tobacco warehouse with the three dimensional form real-time electronic, temperature and humidity, and receive for the receiving trap beyond the tobacco warehouse by wireless transmit, so that being provided accurately, the scientific quantification data in time grasp to operating personnel, the processing correlation circumstance uses;
