Description

Digestive equipment respirator

Technical Field

The utility model relates to a digestive equipment respirator.

Background

Lime digestion is an important link and process in light calcium production, and lime emits a large amount of heat in the digestion process and overflows from digestion equipment with water vapor. The open type slaker has simple structure and convenient heat dissipation, but gradually fades out of the market due to low efficiency, and is replaced by closed continuous slaking equipment, and lime enters the lime slaker through a packing auger. Some equipment manufacturers do not process the wet and hot steam, only leave a vent at the lime feeding port to release moisture, and a few are also provided with respirators, but due to unscientific structure and installation position, a certain part of moisture enters the lime auger, so that lime is digested in advance, and some equipment operation problems are caused.

The open breathing port type equipment has the advantages that lime powder is entrained in water vapor, the air quality can be influenced when the lime powder escapes into the air in a large amount, the alkaline moisture is in contact with the equipment and a workshop and can generate a certain corrosion effect, and meanwhile, the moisture is high in temperature and is a dangerous source of potential safety hazards. Some equipment in the market is provided with a forced respirator, but the structure is not reasonable, the operation control is not in place, the actual treatment effect is not good, and a part of moisture still overflows from some equipment interfaces and enters a lime auger.

SUMMERY OF THE UTILITY MODEL

The invention aims to provide a digestion equipment respirator, which adopts a forced circulation method to treat hot gas generated during digestion and return alkaline moisture to a digester, thereby optimizing the running state of the equipment.

In order to realize the aim, the technical scheme of the utility model is to design a breathing apparatus for digestion equipment, which comprises a breathing apparatus steam exhaust box, a steam exhaust cover, a steam baffle bracket, a steam baffle, a steam exhaust hole, a nozzle box and a nozzle;

the bottom of the spray head box is communicated with the digester and is positioned near the feed inlet of the digester and the auger conveying pipe; the spray head is arranged in the spray head box and is connected with the water pipe; the bottom of the exhaust box of the respirator is communicated with the digester and is positioned at a position far away from the feed inlet of the digester; the nozzle box is communicated with the respirator steam exhaust box through a pipeline, and the nozzle faces the pipeline between the nozzle box and the respirator steam exhaust box; the respirator is characterized in that a steam exhaust cover is arranged at the top of the steam exhaust box of the respirator, a steam exhaust hole is formed in the center of the steam exhaust cover, a plurality of steam baffle plate supports are arranged on the lower surface of the steam exhaust cover, and the steam baffle plates are two-layered and are alternately stacked on the steam baffle plate supports.

The material reaches the digester through the auger conveying pipe, a large amount of high-temperature water vapor is generated through reaction, the spray head is opened, the rear end of the spray head is externally connected with a water pipe, the spray head sprays high-speed water columns towards the direction of the respirator steam exhaust box, after the high-speed water columns are formed, air in the spray head box is taken away by the high-speed water columns, negative pressure is formed, the high-temperature water vapor generated in the digester firstly enters the spray head box due to the negative pressure in the spray head box, then enters the respirator steam exhaust box along with the high-speed water columns, the steam rises in the respirator steam exhaust box, passes through the two layers of water vapor partition plates, part of the steam is condensed into water drops at the water vapor partition plates and falls, the water drops and the high-speed water columns flow back to the digester from the bottom of the respirator steam.

The utility model has the advantages and the beneficial effects that: the utility model relates to a digester equipment respirator forces steam to draw forth, avoids steam to get back to in the auger delivery pipe and the lime material reacts in advance, has guaranteed simultaneously that the digestion reaction goes on in the environment stable relatively sealed.
