Description

Kitchen fume purification and air recycling energy-saving pipeline device and centralized kitchen

Technical Field

Background

The centralized kitchen is an indispensable functional area of many industrial parks, office buildings, large-scale complexes and industrial workshops, and some catering enterprises, hotels and the like have more requirements on the kitchen. The kitchen is complex in design, and the environment protection requires that kitchen oil smoke is required to rise to the highest position of the roof and can be discharged when reaching the discharge requirement. While various systems in the kitchen are complicated; the ventilation engineering further comprises a fire-fighting smoke exhaust system, a general ventilation system at ordinary times, an accident ventilation system and a kitchen smoke exhaust system; the kitchen is inconvenient to use due to the fact that the kitchen fume exhausting system is the largest in air quantity, occupies most of space and is divided into functions and areas; and kitchen equipment is more, and the electric load is big, so the system of simplifying the kitchen becomes the convenient means of solving the current situation of kitchen.

The existing kitchen ventilation systems are divided into four groups, namely: 1. a fire-fighting smoke-discharging system; 2. a general ventilation system at ordinary times; 3. an accident ventilation system; 4. a kitchen fume extraction system; each group of systems also needs to distinguish between an air supply system and an air exhaust system. The fire-fighting system is indispensable, ventilation can be combined with accident ventilation at ordinary times, and a double-speed fan is used for achieving the purpose. The ventilation quantity of the oil smoke exhaust system is maximum and is 60 times/h, the area of a wind shaft is large, and for severe cold and cold areas, the comfort level of users such as chefs is considered, and the heating treatment is also carried out on the air supplement in winter.

For a fresh air heating system for kitchen fume exhaust, a fresh air unit is generally used for heating outdoor air, and most of heat sources are heating hot water. The method occupies a larger space, and the heat source uses hot water of the heating system, so that more heat load is generated, and the building heating system is greatly influenced. The fume exhausting system uses fume purifying integrated device, the fume is exhausted to the atmosphere through the roof air treatment device, and the fume is required to pass through a pipe well when the fume rises to the highest position of the roof, so that the layout of the superstructure and the integrity of the appearance of the building are seriously affected; even the whole construction scheme needs to be adjusted.

In view of this, the present utility model has been made.
