Abstract
The utility model provides a device for collecting a non-methane total hydrocarbon sample of environmental air. The device comprises an upper box body and a lower box body. The device is characterized in that the upper box body and the lower box body are respectively provided with an ice bag made of a rigid material; injector storage grooves are formed in the ice bags; injectors are arranged in the injector storage grooves; positioning devices are arranged in the injector storage grooves; insulation layers are arranged in 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 device, the ice bags made of the rigid materials, so that the influence on an analysis result due to permeation of materials in rubber caps at a high temperature into air in the glass injectors is avoided; the injector storage grooves are formed in the ice bags, so that the injectors can be separately stored and are positioned by the positioning devices, and the collision of the injectors due to scattered storage of the injectors is avoided.
Description
technical field:
The utility model relates to a kind of environmental monitoring utility appliance, is 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 under certain condition through solar radiation, 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 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 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 glass syringe is sealed with rubber cap, 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 piston landing in addition, while checking sample, is also not easy.
utility model content:
The purpose of this utility model is that a kind of NMHC sample collecting apparatus of surrounding air is provided for the problem of above-mentioned existence, 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 object 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, on described ice bag, there is syringe and put groove, described syringe is put 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 groove opposite side, on described register pin, be fixedly connected with bungee, 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 utility model 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; On ice bag of the present utility model, be provided with syringe and put groove, can separately put syringe, and position with locating device, avoided at random the putting between the syringe causing of syringe mutually to collide.
2. locating device of the present utility model is fixed to syringe, and the easy accessibility of taking, and manufactures simple.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
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.
embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand following embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.
Embodiment 1:
As shown in Figure 1: the NMHC sample collecting apparatus of surrounding air of the present utility model, comprise upper box 1 and lower box 2, described upper box and lower box the inside are respectively arranged with the ice bag 3 that rigid material is made, on described ice bag, there is syringe and put groove 4, described syringe is put groove the inside and is provided with syringe 5, described syringe is put has locating device on groove, described upper box and described lower box the inside are respectively arranged with heat-insulation layer 6, have O-ring seal 7 between described upper box and lower box.
Embodiment 2:
The NMHC sample collecting apparatus of the surrounding air described in embodiment 1, described locating device comprises that being positioned at described syringe puts the register pin 8 of groove one side and be positioned at the hook 9 that described syringe is put groove opposite side, on described register pin, be fixedly connected with bungee 10, the other end of described bungee is connected on described hook.
Embodiment 3:
The NMHC sample collecting apparatus of the surrounding air described in embodiment 1 or embodiment 2, described syringe comprises syringe body, described syringe body front end is provided with block 11.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characterictic and is equal to the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to those skilled in the art's common practise.
