Fine atomization flash tank

Abstract

The invention provides a fine atomization flash tank, which comprises an atomizing chamber and a vaporizing chamber, wherein the atomizing chamber is communicated with the vaporizing chamber; a feeding pipe of the fine atomization flash tank is arranged in the atomizing chamber and is provided with a plurality of atomization nozzles; a gas-liquid separator of the fine atomization flash tank is arranged on the vaporizing chamber; the inside of a tank body of the fine atomization flash tank is partitioned into two communicated chambers which are partitioned by a partition plate; the vaporizing chamber is arranged at the upper part of the partition plate; and the atomizing chamber is arranged at the lower part of the partition plate; or two tank bodies are taken as the atomizing chamber and the vaporizing chamber respectively and are communicated through a communicating channel. When the flash tank works, a material can be sprayed into the tank body through the atomization nozzles in a form of disperse droplets; the disperse droplets suspend in a space in the tank body; the surface area is large; vaporization is carried out on the surfaces of all droplets under the condition of low pressure in the tank body; a hydrostatic effect is avoided; the liquid vaporization effect is relatively good; and the defects that a traditional flash tank has the hydrostatic effect and is small in flash evaporation and vaporization surface area are overcome.

Description

technical field [0001] The invention relates to a fine atomization flash tank, which belongs to the field of chemical equipment. Background technique [0002] Flash tank plays a key role in light industry, chemical industry, metallurgy, building materials and other industries. Due to its small footprint, continuous production, good reliability, high degree of automation, and no pollution to the environment. Flash evaporation is when water enters the flash tank. Due to the sudden drop in pressure, the boiling point of water decreases accordingly, which makes the water vaporize rapidly, and the water vapor is extracted from the flash tank. The boiling point of water increases with the increase of pressure, conversely, the lower the pressure, the lower the boiling point. The principle of flash evaporation is to keep high-pressure and high-temperature water in a low-pressure environment to lower its boiling point. When the water temperature is higher than the boiling point und...

Problems solved by technology

However, the traditional flash tank usually maintains a certain water level, and there is inevitably a static pressure effect. The vaporization mainly occurs on the surface of the liquid level, and the part below the liquid level is affected by the static pressure, and the boiling vaporization capacity decreases.

The traditional flash tank does not emphasize the influence of the size of the liquid droplets sprayed from the nozzle on the feed pipe on the flash tank flash effect, and there is no physical part designed to divide the tank cavity into two chambers with different functions
