Abstract

The utility mode discloses a seven-pipe heater, which comprises a steam pipe (1), inside which seven material circulation pipes (2) are evenly distributed. Compared with the prior art, the seven-pipe heater has the advantages that: as the seven material circulation pipes are arranged in the same environment and can be heated evenly, the treatment capacity is improved and the construction investment is reduced. As the total length is shortened, the scabbing rate of the material circulation pipes is reduced; the heat exchanging is more complete, therefore the energy consumption is reduced and the maintenance cost decreases at the same time.

Description

Seven double pipe heaters

Technical field:

The utility model belongs to the double pipe heater of aluminum oxide pipeline stripping.

Technical background:

In aluminum oxide stripping production process, the single double pipe heater that uses is that a less feed-pipe of diameter is arranged in the big vapour pipe of a diameter at present, for guaranteeing the higher solubility rate of aluminum oxide, wants to improve output; Need to adopt the lengthening flow process and the increase residence time to achieve the goal.Will certainly cause investment to increase like this, easily scab defectives such as energy consumption increase in the production.

The utility model content:

The technical problems to be solved in the utility model is: by the layout and the radical of reasonable arrangement streams siphunculus, so that improve treatment capacity, reduce manufacturing expense, reduce production costs.

Formation of the present utility model: it comprises vapour pipe (1), evenly is furnished with 7 streams siphunculus (2) in vapour pipe (1).

The arrangement form of 7 streams siphunculus (2) is: center arrangement is 1 in vapour pipe (1), and 6 of arranged around are rationally controlled every pipe compartment distance, clamps by unit clamp to get final product.

The utility model compared with prior art because seven streams siphunculus are in energy thermally equivalent under the identical environment, makes treatment capacity improve, and construction investment reduces.Owing to shortened length overall, material stream passed duct ligation scar rate is reduced, heat exchange is more abundant, and energy consumption also just reduces, and maintenance cost also reduces simultaneously.

Description of drawings:

Fig. 1 is a synoptic diagram of the present utility model;

Fig. 2 is that the A of Fig. 1 is to figure.

Embodiment:

Embodiment of the present utility model: 7 streams siphunculus 2 are evenly arranged in the vapour pipe 1.The arrangement form of 7 streams siphunculus 2 is: center arrangement is 1 in vapour pipe 1, and 6 of arranged around are rationally controlled every pipe compartment distance, clamps by unit clamp to get final product.

Claims (2)

1. double pipe heater, it comprises vapour pipe (1), it is characterized in that: evenly be furnished with 7 streams siphunculus (2) in vapour pipe (1).

2. seven double pipe heaters according to claim 1 is characterized in that: the arrangement form of 7 streams siphunculus (2) is: center arrangement is 1 in vapour pipe (1), 6 of arranged around.
