Abstract
A kind of novel distillation tower, comprise tube connector, lower tube connector, inner and outer tank, described inner canister is positioned at outer tank, the two ends up and down of described inner and outer tank are all respectively arranged with upper shed and under shed, the upper shed of described inner and outer tank is all welded to connect with upper tube connector the inner, the under shed of described inner and outer tank is all welded to connect with lower tube connector the inner, gap is provided with between the tube wall of described inner and outer tank, inert gas is filled with in described gap, be provided with pressure tester in described gap, the width in described gap is 1 ~ 2mm.Novel distillation tower arranges two-layer tank body, has inert gas in gap, can after inner canister is leaked, memory leak material, avoids causing blast or noxious material to leak outside material from leakage to tower, causes security incident.The pressure tester installed in gap can occur to detect when leaking that the pressure between tank body changes in inner canister, and prompting monitor staff inner canister is leaked, and guides it to adopt an effective measure.Inner and outer tank, by being welded to connect, ensure that sealing good in tank body.
Description
Technical field
The utility model relates to chemical technology field, specifically, is a kind of rectifying column.
Background technology
Rectifying column is the gas-liquid mass transfer (contact) equipment extensively adopted in the production processes such as chemical industry, petrochemical industry, biology, pharmacy, can realize separating substances according to the difference of each component volatilization degree.In actual production operation, because material may have corrosivity or toxicity, or hydrogeneous medium easily produces hydrogen crack, rectifying column tower body generally there is weld seam, also easily there is rough position in tower body surface, these positions easily cause hydrogen to assemble, under effect of stress, can crack, also may there is the situation of manual operation error, these reasons all likely cause rectifying column to leak, material contacts with air, and then explosion caused, occurs security incident, injure personal safety and health, cause economic loss.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, devises a kind of novel rectifying column.
Novel distillation tower of the present utility model, comprise tube connector, lower tube connector, inner and outer tank, described inner canister is positioned at outer tank, the two ends up and down of described inner and outer tank are all respectively arranged with upper shed and under shed, the upper shed of described inner and outer tank is all welded to connect with upper tube connector the inner, the under shed of described inner and outer tank is all welded to connect with lower tube connector the inner, gap is provided with between the tube wall of described inner and outer tank, inert gas is filled with in described gap, be provided with pressure tester in described gap, the width in described gap is 1 ~ 2mm.
Preferably, the upper shed of described inner and outer tank is all welded on the same position of tube connector the inner, and the under shed of described inner and outer tank is all welded on the same position of lower tube connector the inner.
The beneficial effects of the utility model are: novel distillation tower arranges two-layer tank body, has inert gas in gap, can after inner canister is leaked, memory leak material, avoid causing blast or noxious material to leak outside material from leakage to tower, cause security incident.The pressure tester installed in gap can occur to detect when leaking that the pressure between tank body changes in inner canister, and prompting monitor staff inner canister is leaked, and guides it to adopt an effective measure.Inner and outer tank, by being welded to connect, ensure that sealing good in tank body.Gap width is moderate, being formed double-deck while, can not increase considerably the volume of rectifying column, also significantly can not reduce the volume of rectifying column.Inner and outer tank are all welded to the same position of corresponding tube connector, and make to be welded to connect position thickness comparatively large, bonding strength is high, good seal performance.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this novel distillation tower.
Detailed description of the invention
Novel distillation tower of the present utility model, as shown in Figure 1, comprises tube connector 1, lower tube connector 2, inner canister 3 and outer tank 4.
Inner canister 3 is positioned at outer tank 4, the two ends up and down of inner canister 3 and outer tank 4 are all respectively arranged with upper shed 5 and under shed 6, the upper shed of inner canister 3 and outer tank 4 is all welded to connect with upper tube connector 1 the inner, and the under shed 6 of inner canister 3 and outer tank 4 is all welded to connect with lower tube connector 2 the inner.
Be provided with gap 7 between the tube wall of inner canister 3 and outer tank 4, be filled with inert gas in gap 7, be provided with pressure tester in gap 7, load cell comprises baroceptor, and the width in gap 7 is 1 ~ 2mm.
During use, material carries out separating substances in rectifying column, and when causing inner canister 3 to leak due to material characteristic or manual operation error, the material leaked out enters into the inert gas in gap 7, avoids blasting in material from leakage to air.
Due to entering of material, the pressure in gap 7 changes, and pressure tester detects the change of pressure, and alert rectifying column leaks, and guides it to adopt an effective measure.
