The utility model discloses the device that to prepare formaldehyde falls into three level and distributes and installs in the truss is born to the multilayer, and the destruction that makes each equipment not receive external natural environment avoids causing the corruption of equipment and the structure problem of applying equipment that wind carried or external load produces, each equipment structure arranges the compactness, has reduced the connection tube side, has improved economic benefits, the absorption tower device of preparation formaldehyde is too high, and the portion sets up a cape above that, avoids sleet attached to absorption tower surface, improve equipment's life.
Description
Technical field
The utility model belongs to prepares formaldehyde equipment technical field, particularly relates to a kind of system and device for the preparation of formaldehyde.
Background technology
Paraformaldehyde (PF) and formaldehyde are industrial important linear yubans.When preparing formaldehyde and derived prods, connect complicated between each equipment, locus requires too much, and the completely exposed destruction being easily subject to physical environment in atmosphere of some equipment, equipment surface, under the impact of rainwater or snow, easily causes surface corrosion, and it is comparatively obvious that corrosion occurs in each junction.And it is comparatively large that the formaldehyde system and device due to plane formula takes up an area face, and tube side consumption is larger.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of system and device for the preparation of formaldehyde, and the device preparing formaldehyde is divided into three level distributing installations in multilayer load truss, each device structure characteristics of compact layout, decreases connection tube side.
The utility model is achieved through the following technical solutions:
The utility model provides a kind of system and device for the preparation of formaldehyde, comprises load truss, and described load truss comprises the first layer framework, second layer framework and third layer framework; Between described the first layer framework and second layer framework, between second layer framework and third layer framework, be connected to cat ladder; Described load truss is provided with ceiling; Described the first layer framework is provided with absorption tower, and a butterfly cape is fixed at top, described absorption tower.
Further, described the first layer framework is also provided with oxidizer, methyl alcohol strainer, methanol evaporator and tail gas roots blower.
Further, described second layer framework is provided with First Heat Exchanger, the second interchanger, tail gas flame arrester and air filter.
Further, described third layer framework is provided with bubble-cap circulation groove, oxidizer bag and the level tank for oxidizer bag.
Further, the preferred stainless steel metal of described butterfly cape or alloy aluminum, external diameter is 2-3 times of absorption tower.
The utility model has following beneficial effect:
The device preparing formaldehyde is divided into three level distributing installations in multilayer load truss by the utility model, makes each equipment not by the destruction of extraneous physical environment, avoids the corrosion causing equipment, and to the structure problem that wind carries or external load produces that equipment applies; Each device structure characteristics of compact layout, decreases connection tube side, improves economic benefit; The absorption tower device preparing formaldehyde is too high, arranges a cape at an upper portion thereof, avoids sleet to be attached to surface, absorption tower, improves the work-ing life of equipment.
Certainly, implement arbitrary product of the present utility model might not need to reach above-described all advantages simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, be briefly described describing the required accompanying drawing used to embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of system apparatus arrangements figure for the preparation of formaldehyde of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to shown in Fig. 1, the utility model is a kind of system and device for the preparation of formaldehyde, comprises load truss 1, and load truss 1 comprises the first layer framework 101, second layer framework 102 and third layer framework 103; Cat ladder 104 is connected between the first layer framework 101 and second layer framework 102, between second layer framework 102 and third layer framework 103; Load truss 1 is provided with ceiling; The first layer framework 101 is provided with absorption tower 2, and a butterfly cape 201 is fixed at top, described absorption tower 2.
Wherein, the first layer framework 101 is also provided with oxidizer 4, methyl alcohol strainer 5, methanol evaporator 3 and tail gas roots blower 6.
Wherein, second layer framework 102 is provided with First Heat Exchanger 7, second interchanger 8, tail gas flame arrester 9 and air filter 10.
Wherein, third layer framework 103 is provided with bubble-cap circulation groove 11, oxidizer bag 12 and the level tank 13 for oxidizer bag.
Wherein, butterfly cape 201 is stainless steel metal or alloy aluminum preferably, and external diameter is 2-3 times of absorption tower 2.
In the present embodiment, butterfly cape 201 adopts stainless steel metal to make, and butterfly cape 201 is greater than the external diameter on absorption tower 2, is enclosed within the end cap on absorption tower 2, enters in load truss 1 along absorption tower 2 for avoiding rainwater.The ceiling that load truss 1 top is arranged is used for preventing external environment PARA FORMALDEHYDE PRILLS(91,95) production unit from causing adverse influence; Load truss 1 adopts the structure of layer-stepping, makes between formaldehyde production equipment compacter, reduces floor space, the tube side between reduction equipment.
Because the height on absorption tower 2 is higher, exceed load truss 1 top one segment distance (exceeding distance at 3-5m), in order to prevent external environment (rainwater, snow, the hail etc.) impact on equipment, generally can cause the corrosion that equipment is certain, reducing the work-ing life of equipment.
