Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings.

[0009] Such as figure 1 As shown, a maleic anhydride reaction cooling device of the present invention includes a housing 1, a plurality of cooling rods 2 inserted into the housing 1 from above, and partitions are arranged between adjacent cooling rods 2 . The baffles include lower baffles 3 with gaps in the upper parts and upper baffles 4 with gaps in the lower parts; the upper baffles and the lower baffles are arranged alternately.

[0010] In the embodiment, there are 6 cooling rods plugged into the housing, which are filled with cooling liquid, and 5 fast partitions are arranged between the 6 cooling rods. According to the distribution, one time is the lower partition, the upper partition, the lower partition, The upper partition and the lower partition evenly distribute the space to ensure the condensation effect.

[0011] The above is only a preferred embodiment...

Abstract

The invention discloses a maleic anhydride reaction cooling device. The maleic anhydride reaction cooling device comprise a housing and a plurality of condensation bars inserted into the housing from the top, wherein a partition plate is arranged between two adjacent condensation bar; the partition plates comprise lower partition plates with gaps reserved atthe tops and upper partition plates with gaps reserved at the bottoms; the upper partition plates and the lower partition plates are arranged alternately. Due to the addition of the partition plates, the cooling effect is optimized; due to the density of the mixed gas, the mixed gas is unevenly distributed in the housing, resulting in that the cooling effect is limited and merely completed by part of the condensation bars; due to the addition of the partition plates, maleic anhydride gas subjected to oxidation reaction is evenly distributed in the space of the housing. The reaction cooling device is simple in structure, optimized in space configuration and obvious in effect.

Description

technical field [0001] The invention relates to the field of chemical production, in particular to a maleic anhydride reaction cooling device. Background technique [0002] In the existing maleic anhydride production, after the reaction oxidation, the temperature of the mixed gas is very high, even higher than the spontaneous ignition point, which is very easy to cause spontaneous combustion, while the maleic anhydride reaction cooling device realizes the cooling of the mixed gas, so as to ensure the normal and safe operation of the process. . However, the cooling effect of existing coolers is average, and generally only about 40% of the gas-phase maleic anhydride is condensed, and the efficiency is low, which increases the production cost. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a maleic anhydride reaction cooling device that improves condensation efficiency and co...
