Abstract
The invention relates to an adsorption column for a detachable casing pipe structure for recycling CDI tail gas and belongs to the technical field of polycrystalline silicon production equipment. The adsorption column comprises a tower body (1), an array pipe (2), an outer semi-pipe annual pipe (3) and a skirt base (4), wherein the outer semi-pipe annual pipe (3) is arranged on an outer wall of the tower body (1); the array pipe (2) is inserted into the tower body (1); the array pipe (2) comprises a casing pipe support (2-1), a plurality of outer casing pipes (2-2), a plurality of inner casing pipes (2-3), an outer casing pipe annular pipe (2-4) and an inner casing pipe annular pipe (2-5); the outer casing pipes (2-2) are supported on an inner wall of the tower body (1) by the casing pipe support (2-1); the inner casing pipes (2-3) are inserted into the outer casing pipes (2-2); the outer casing pipes (2-2) are connected by the outer casing pipe annular pipe (2-4); and the inner casing pipe annular pipe (2-5) is connected with the inner casing pipes (2-3) through a flange (2-6), a gasket (2-7) and a fastener (2-8). The independent detachability of the inner casing pipes and the outer casing pipes is realized by detaching the fastener.
Description
Technical field
The present invention relates to a kind of CDI tail gas recycle and use adsorption column, be specifically related to a kind of polysilicon industry tail gas recycle with removable sleeve structure adsorption column.Belong to the polycrystalline silicon production device technical field.
Background technology
At present, along with the continuous increase of global energy demand, the higher energy prices and the public have opened market for solar cell for the concern of global warming issue.High purity polycrystalline silicon is as the key material of semicon industry and photovoltaic industry, because its distinctive good characteristic becomes irreplaceable strategic resource.And in production of polysilicon, tail gas recycle has become the industry inevitable problem.
1, in the production of polysilicon, can produce a large amount of tail gas, and the environmental protection pressure that tail gas causes has become serious social concern.Effectively utilize tail gas, reducing environmental pollution is the current matter of utmost importance that must solve.
2, the cost pressure of each production technology enterprises and institutions, the downslide of polysilicon price in the international environment of present global financial crisis, has forced domestic production of polysilicon enterprise must consider the comprehensive reutilization to tail gas.
Polysilicon tail gas reclaims with adsorption column and accomplishes the purification to tail gas, for next step recycling provides purity higher hydrogen, with the generation that directly influences the reduction furnace silicon rod, the yield that improves reduction furnace is played crucial effects.There is following problem in present adsorption column:
The coil arrangement (like Fig. 3) of adsorption column inside is owing to making and use reason, and coil pipe is easy to leak, and causes interior hot water of coil pipe or steam to enter in the adsorbent, causes the adsorbent inefficacy, and can't repair, and whole equipment faces and scraps.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of air inlet pipe removable removable sleeve structure adsorption column.
The objective of the invention is to realize like this: a kind of removable sleeve structure adsorption column, comprise tower body, tubulation, outer semicanal endless tube and skirt, outer semicanal endless tube is arranged at the tower body outer wall; Tubulation inserts in the tower body; Said tubulation comprises collar supports, outer tube, inner sleeve, outer tube endless tube and inner sleeve endless tube, and outer tube has many, and inner sleeve also has many; Collar supports is supported in the tower body inwall with outer tube; Inner sleeve is inserted in the outer tube, and the outer tube endless tube couples together many outer tubes, and the inner sleeve endless tube is connected with many inner sleeves through flange, pad and securing member.
The invention has the beneficial effects as follows:
1, the present invention adopts tubular structure little than coil arrangement shaping attenuate amount, and weld seam is few, and the possibility of corrosion leakage is less.
2, tubulation avoids entire equipment to scrap just in case leak and can change by root, saves production cost.
Through above-mentioned air inlet pipe removable structure, can prolong the whole service life of adsorption column equipment to a greater extent, effectively save production cost.
