Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further explained:

[0017] see figure 1 with figure 2 , comprising a housing 1 provided with a feed pipe 4, a discharge pipe 5 and a gas outlet 6, the bottom surface of the housing 1 is an inclined plane 2, and its inclination angle a is 12°;

[0018] The feed pipe 4 and the discharge pipe 5 are located on the side wall of the housing 1 at the lower end of the slope 2, and the opening lower ends of the feed pipe 4 and the discharge pipe 5 are flush with the slope. The front section of the feed pipe 4 is at the same angle of inclination as the slope 2 and is tangent to the side wall of the casing 1, and the front section of the discharge pipe 5 is at the same angle and direction as the slope 2;

[0019] A partition 3 is arranged between the feed pipe 4 and the discharge pipe 5 at the bottom of the housing. The rear end of the partition is fixed on the side wall of the housing at the lower e...

Abstract

The invention discloses a high-level flash cooler for wet-process phosphoric acid, which solves the problems of the existing high-level flash cooler that materials are easy to boil, easy to accumulate, difficult to clean and high investment cost. The technical solution includes a casing provided with a feed pipe, a discharge pipe and a gas outlet, the bottom surface of the casing is a slope, the feed pipe and the discharge pipe are located on the side wall of the casing at the lower end of the slope, the A partition is arranged between the feed pipe and the discharge pipe at the bottom of the housing, the rear end of the partition is fixed on the housing side wall at the lower end of the slope, and there is a gap between the front end and the housing side wall at the high end of the slope. The invention has extremely simple structure, easy operation, low production cost and investment cost, effectively reduces the occurrence of accumulation and blockage problems, high safety and reliability, and good flash cooling effect.

Description

technical field [0001] The invention relates to equipment in the field of chemical industry, in particular to a flash cooler. Background technique [0002] The function of the flash cooler is to boil the solution (usually water) on the product through decompression, so that the product can produce two states of vapor and liquid. The principle is that the high-temperature product suddenly enters the high-vacuum chamber, and the solution in the product will rapidly expand and vaporize due to the high-pressure volume, so that more solution (usually water) flashes into a vapor state, and achieves cooling and concentration under high vacuum. Purpose. The traditional flash cooler usually adopts a cone bottom structure, and the material enters axially from the wall of the equipment and exits from the bottom of the cone bottom. For example, Patent No. CN 103041608 A discloses a novel evaporator discharge flash cooling device, wherein the vacuum ejector is connected with the flash ...
