Embodiment approach

[0027] As an embodiment of the present invention, the fixing part 417 is an annular deflector 418; the annular deflector 418 is sleeved on the side wall of the No. 1 turntable, and the annular deflector 418 is installed on the niacin tank 1, the annular guide plate 418 is used to guide the flow direction of the steam downward. The steam will first blow down the niacin, thereby stirring the niacin below, and then the steam will float up to stir the niacin above, thus increasing the range of steam stirring and further improving the uniformity of niacin being evaporated.

[0028] As an embodiment of the present invention, the sides of the No. 1 disc 413 and the No. 2 disc 414 that are close to each other have a wave-shaped structure, and the wave-shaped structure can increase the contact area with the steam; When flowing between the disc 413 and the second disc 414, the heating speed of the first disc 413 and the second disc 414 is accelerated.

Abstract

The invention belongs to the technical field of sulfuric acid production equipment, and particularly relates to a sulfuric acid evaporator. The sulfuric acid evaporator comprises a nicotinic acid tank, a water vapour tank and a support; the water vapour tank is arranged on the lower side of the nicotinic acid tank; the nicotinic acid tank is vertically arranged on the ground through the support; the interior of the water vapour tank is divided into a steam bin and a condensation bin by a partition board; a steam inlet is formed in the side wall of the steam bin; a condensate water outlet is formed in the bottom of the side wall of the condensation bin; through cooperation of each straight pipe, each curved pipe, a first round disk and a second round disk, a corresponding U-shaped pipelineprovided with multiple gaps is formed, so that the problem of exorbitant cost caused by using an overlong U-shaped pipeline is avoided; by forming the 0.01-mm gaps in the U-shaped pipelines, by meansof vomited steam, on one hand, nicotinic acid can be prevented from flowing into the U-shaped pipelines, so that a sealing effect is achieved, and on the other hand, the nicotinic acid can be stirredto make the nicotinic acid evenly evaporated.

Description

technical field [0001] The invention belongs to the technical field of sulfuric acid production equipment, in particular to a sulfuric acid evaporator. Background technique [0002] Sulfuric acid is an important basic chemical raw material and the basic raw material of the chemical industry. The output of sulfuric acid is one of the indicators of the production capacity of a country's chemical industry. Among them, refined sulfuric acid, as one of the fine chemicals, is widely used in electronic communication, medicine and other industries, and can also be used as a raw material for chemical reagents and batteries. Refined sulfuric acid is a colorless transparent oily liquid with strong oxidizing, water-absorbing, dehydrating and corrosive properties. SO in nicotinic acid 3 Gas evaporative separation is a step in the current process of producing refined acid, and the SO in niacin 3 Gas evaporative separation is to use sulfuric acid evaporator to heat and evaporate nicotin...
