Abstract
The invention provides a non-methane total hydrocarbon sample collection device for ambient air. The device comprises an upper box body and a lower box body, and is characterized in that ice bags made of rigid materials are arranged inside the upper box body and the lower box body respectively; syringe placing grooves are formed in each ice bag; a syringe is arranged inside each syringe placing groove; a positioning device is arranged on each syringe placing groove; insulating layers are arranged inside the upper box body and the lower box body respectively; a seal ring is arranged between the upper box body and the lower box body. According to the invention, the phenomenon that air in the glass syringe can permeate into substances in a rubber cap under high temperature to have influence on an analysis result can be avoided in virtue of the arranged ice bags made of rigid materials; the syringe placing grooves formed in the ice bags can be used for placing the syringes in a separated manner, and the positioning devices can be used for positioning, so that the mutual collision of syringes caused by the disordered placement of syringes is avoided.
Description
Technical field:
The present invention relates to a kind of environmental monitoring utility appliance, be specifically related to a kind of NMHC sample collecting apparatus of surrounding air.
Background technology:
NMHC (non methane total hydrocarbon, NMHc) is the general name that is present in all hydrocarbons except methane in surrounding air.NMHC in atmosphere surpasses finite concentration, except directly health being harmful to, can also produce photo-chemical smog through solar radiation under certain condition, and environment and the mankind are worked the mischief.The domestic sampling work about surrounding air NMHC parameter is substantially all to adopt glass syringe to collect air sample at present, then, with the rubber cap sealing, analyzes the same day as far as possible.Because general non-methane sample sampled point is more, with plastic crate, carry out the needle tubing transportation.The problem that this sampling apparatus exists has: at heat, and in the situation that sample can not be analyzed the same day, if now with rubber cap, glass syringe is sealed, thereby the air that the material in rubber cap can penetrate in glass syringe exerts an influence to analysis result; The transportation of plastics large bamboo or wicker basket easily causes syringe to break or the piston landing in addition, while checking sample, also is not easy.
Summary of the invention:
The objective of the invention is to provide for the problem of above-mentioned existence a kind of NMHC sample collecting apparatus of surrounding air, can avoid rubber cap in the situation of heat is the pollution that sample causes, and convenient transportation, be convenient to check, guarantee the accuracy of sampling, for environment measuring provides important foundation.
Above-mentioned purpose realizes by following technical scheme:
The NMHC sample collecting apparatus of surrounding air, comprise upper box and lower box, described upper box and lower box the inside are respectively arranged with the ice bag that rigid material is made, there is syringe on described ice bag and put groove, described syringe is put the groove the inside and is provided with syringe, described syringe is put on groove has locating device, and described upper box and described lower box the inside are respectively arranged with heat-insulation layer, between described upper box and lower box, have O-ring seal.
The NMHC sample collecting apparatus of described surrounding air, described locating device comprises that being positioned at described syringe puts the register pin of groove one side and be positioned at the hook that described syringe is put the groove opposite side, be fixedly connected with bungee on described register pin, the other end of described bungee is connected on described hook.
The NMHC sample collecting apparatus of described surrounding air, described syringe comprises syringe body, described syringe body front end is provided with block.
Beneficial effect:
1. the present invention is provided with the ice bag that rigid material is made, while going out to sample, first to ice bag, carry out cooling, the slow released cold quantity of refrigerant in ice bag, can keep for a long time ice bag at lower temperature, thereby avoid the air that under high temperature, the material in rubber cap can penetrate in glass syringe to exert an influence to analysis result; Be provided with syringe on ice bag of the present invention and put groove, can separately put syringe, and position with locating device, avoided at random the putting between the syringe caused of syringe mutually to collide.
2. locating device of the present invention is fixed to syringe, and the easy accessibility of taking, and manufactures simple.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
In figure: 1, upper box, 2, lower box, 3, ice bag, 4, syringe puts groove, 5, syringe, 6, heat-insulation layer, 7, O-ring seal, 8, register pin, 9, hook, 10, bungee, 11, block.
