Embodiment 1

[0020] There are 44 open electrolytic cells in a tall cobalt electrodeposition workshop, which are placed in an area with a length of 48m, a width of 27m, and a height of 14m, which is half of the volume of the workshop. When the electrolyte cobalt chloride solution is heated to 55-65°C, it decomposes to generate chlorine gas. Although most of the hot gas from the electrolyte is discharged through the tank side process recovery pipe, part of the chlorine vapor is still emitted indoors as the hot gas rises. In general, windows are opened in the workshop for natural ventilation. When the wind and sand come and close the windows, the personnel in protective clothing and masks can only operate for a while, and the environment is very harsh.

[0021] (1) Properties of chlorine gas

[0022] Chlorine is a poisonous gas with a strong, choking odor. In a near-standard state, the vapor density of chlorine gas is 2.49kg / m 3 , 2 times higher than air. Therefore, when chlorine gas is ...

Abstract

The invention relates to a ventilation method for an open reaction groove tank in a large space workshop. The replacement ventilation provided by the invention adopts the method that the fresh air is fed from the upper part of the reaction tank; the harmful gas is exhausted from the lower part of the reaction tank, so as to form a converse airflow distribution; supposed the harmful gas is distributed in closed space around the reaction tank; the distribution quantity of the harmful gas is calculated; the air replacement quantity for diluting the harmful gas is calculated according to the distribution quantity of the harmful gas. Compared with the general ventilation, the entire displacement quantity of the displacement ventilation method is saved by a half; thereby, the energy consumptionof the ventilation system is reduced; the upper feeding and lower exhaust airflow distribution can effectively dilute the concentration of the harmful gas and ensures the concentration of the harmfulgas to be lower than the highest allowed concentration of the harmful gas in the operation area; meanwhile, the erosion on the construction rigid frame structure is reduced.

Description

technical field [0001] The invention relates to a ventilation method for a large-space factory building with an open reaction tank. Background technique [0002] In the tall factory building of the smelting industry, the open process reaction tank emits a large amount of acid mist and hot gas, which volatilizes upward and spreads around. It directly endangers the workers, seriously corrodes the steel structure, and reduces the service life of building materials. [0003] In order to dilute the concentration of harmful gases and ensure indoor hygiene standards, traditional ventilation forms mainly include the following: [0004] 1) overall ventilation [0005] Natural ventilation is generally through skylights or doors and windows, unorganized air intake and exhaust, air flow in and out, which is not suitable for closed workshops or sandstorm seasons. [0006] Mechanical ventilation is usually an exhaust fan installed on the outer wall or roof of the workshop, and the air ...
