Variable gas distribution mechanism and rotary combustion chamber and air valve device

A variable admisssion mechanism is composed of a movement switching unit, actuator and planetary gear train. It can continuously regulate 4 key phase angles and phases of admission gate and exhaust gate for increasing the flow of air flowing through air gate to improve combustion condition and increase output power. Its rotary combustion chamber and air gate unit is a rotary body integrating combustion chamber, admission gate and exhaust gate.

Chromium- and aluminum-containing mud alkaline-method recycling process

The invention discloses a chromium- and aluminum-containing mud alkaline-method recycling process, which comprises: adding water into chromium- and aluminum-containing mud to make slurry, adding sodium hydroxide till the pH value of the slurry is more than or equal to 10.8, adding a reducer into the slurry, and heating the slurry till the slurry boils to obtain a deep green precipitate; filteringthe slurry; washing the filter cake with hot water at a temperature above 50 DEG C, adding acid to neutralize the filter cake, washing the filter cake with hot water, filtering the filter cake, and obtaining the filter cake which is Cr(OH)3; and adding an acid into the filtrate for acidification, filtering the filtrate, adding an alkali into the filtrate for neutralization to obtain a white precipitate, washing and drying the white precipitate to obtain a Al(OH)3 PRODUCT. The process adopts normal operation, avoids using a large amount of energy and discharging three wastes, and realizes low labor ...

Acid method recycling process of chromium-containing aluminum mud

The invention discloses an acid method recycling process of chromium-containing aluminum mud, which comprises the following steps: first adding water and beating the chromium-containing aluminum mud, adding inorganic acid or sodium acid sulfate to the solution, then adding in reducing agent, heating and boiling to produce dark green precipitate; filtering; washing a filter cake with 50DEG C hot water until the washing liquid does not turn white, filtering, and the filter cake is Cr(HO)3; adding the inorganic acid into filtrate to produce white precipitate, filtering, drying the filter cake toobtain an Al(OH)3 product; and the process is conventional operation which has the advantages of no consumption of a large amount of energy, no discharge of waste water, waste gas and solid waste, low labor intensity, easily controlled process, thorough recycling of chromium aluminum and high production efficiency.
