Description
Technical field
The utility model relates to deep cooling storage tank field, particularly a kind of deep cooling storage tank interlayer gas analysis and filter device.
Background technology
Along with fast development of national economy, (be called for short vat, volume is at 200m for large-scale deep cooling storage tank
3More than) because its storage capacity is big, the storage safe characteristic, quilt just more and more widely applies to all trades and professions.Simultaneously, along with the fast development of empty branch trade technology, the empty maximization that divides is also becoming generalization; And the support equipment of storing as its cryogenic liquid, large-scale deep cooling storage tank is also increasing to be used, as large-scale deep cooling storage tank; Because its storage capacity reaches deep cooling (196 ℃) characteristic greatly, therefore, its security and economy are also very important; In case storage tank inside groove generation micro-leakage, and in time do not find, if this leakage betides the top; Then the major disaster accident if leakage point betides the bottom liquid phases part, will take place in the just loss of gas.Therefore, before little leak source does not also lead to major break down, be necessary to examine in advance knowledge; In time solve, and will in time examine to know whether this phenomenon takes place, be necessary storage tank interlayer gas is analyzed; There is abnormal occurrence to take place in case analyze, should in time takes treatment measures, guarantee storage tank safety.
As the cryogenic liquid storage tank, because interlayer is the dusty material insulation, during to the direct sample of deep cooling storage tank interlayer gas, dusty material meeting blocking pipe causes the sampling failure.
Summary of the invention
The utility model technical matters to be solved is to above-mentioned prior art present situation, provide simple in structure, can not the insulation clogged with material, sampling is effective, can effectively detect a kind of deep cooling storage tank interlayer gas analysis and filter device that deep cooling storage tank gas leaks.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of deep cooling storage tank interlayer gas analysis and filter device; Comprise analyzing and take over, wherein, analyze interconnective gas collecting portion and the gas transmission portion of comprising that take over; Gas collecting portion includes cartridge filter; Cartridge filter is an antipriming pipe, and the cartridge filter outer peripheral face is enclosed with filter cloth and silk screen spare from inside to outside successively, and the cartridge filter end is connected with the end cap that can stop the insulation powder to get into cartridge filter.
For optimizing technique scheme, the concrete measure of taking also comprises:
Above-mentioned cartridge filter end is fixedly connected with filter cloth and silk screen spare through securing member, and the fitting together through the anchor ear with pressuring action with filter cloth, silk screen spare of cartridge filter.
Above-mentioned gas collecting portion is fixedly connected through connector with gas transmission portion.
The housing of above-mentioned gas transmission portion and the welding of deep cooling storage tank shell are fixing.
Above-mentioned gas transmission portion end is provided with and is used for and draws and take over the joint be connected.
Above-mentioned joint and the connected mode of drawing adapter are for being threaded.
Above-mentioned cartridge filter is that screw is connected or rivet connects or welding with the connected mode of end cap.
Above-mentioned cartridge filter and end cap are integral piece.
Compared with prior art, a kind of deep cooling storage tank interlayer gas analysis and filter device of the utility model comprises analyzing and takes over; Wherein, Analyze adapter and comprise interconnective gas collecting portion and gas transmission portion, gas collecting portion includes cartridge filter, and cartridge filter is an antipriming pipe; The cartridge filter outer peripheral face is enclosed with filter cloth and silk screen spare from inside to outside successively, and the cartridge filter end is connected with the end cap that can stop the insulation powder to get into cartridge filter.The utility model is loaded on the densely covered zone of discharging tube, after interlayer is full of Powdered insulation material, carries out multiple separation through filter cloth and silk screen spare; Dusty material can't enter in the cartridge filter, has been in the filter cylinder but gas can penetrate filter cloth and silk screen spare and get into, and gas is through inflow gas transmission portion of gas collecting portion; And introduce the pulpit through gas transmission portion and analyze, change the content abnormal ascending of the gas componant that especially is stored if find the gas componant content of analyzing; The gas leakage had taken place near the position at gas collecting portion place then was described; When in the storage tank inside groove takes place, leaking, stored-gas can be full of whole interlayer, because the thickness of interlayer is all more than 1200mm; General leakage is difficult to observation; Have only analytical sampling, could learn in time whether interbedded gas has unusually, thereby can judge the security of storage tank through interlayer gas.The utlity model has simple in structure, can not the insulation clogged with material, sampling is effective, can effectively detect the advantage that deep cooling storage tank gas leaks.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment to the utility model describes in further detail below in conjunction with accompanying drawing.
Shown in Figure 1 is the structural representation of the utility model.
Reference numeral wherein is: analyze adapter 1, gas collecting portion 2, gas transmission portion 3, end cap 4, silk screen spare 5, filter cloth 6, cartridge filter 7, securing member 8, anchor ear 9, joint 10.
As shown in Figure 1, a kind of deep cooling storage tank interlayer gas analysis and filter device of the utility model comprises analyzing and takes over 1; Wherein, Analyze adapter 1 and comprise interconnective gas collecting portion 2 and gas transmission portion 3, gas collecting portion 2 includes cartridge filter 7, and cartridge filter 7 is an antipriming pipe; Cartridge filter 7 outer peripheral faces are enclosed with filter cloth 6 and silk screen spare 5 from inside to outside successively, and cartridge filter 7 ends are connected with the end cap 4 that can stop the insulation powder to get into cartridge filter 7.
Among the embodiment, cartridge filter 7 ends are fixedly connected with filter cloth 6 and silk screen spare 5 through securing member 8, and the fitting together through the anchor ear 9 with pressuring action with filter cloth 6, silk screen spare 5 of cartridge filter 7, and securing member 8 is bolt, the nuts and washers that cooperatively interacts.
Among the embodiment, gas collecting portion 2 is fixedly connected through connector 11 with gas transmission portion 3.
Among the embodiment, the housing of gas transmission portion 3 and the welding of deep cooling storage tank shell are fixing.
Among the embodiment, gas transmission portion 3 ends are provided with and are used for and draw and take over the joint 10 be connected.
