Description

A comprehensive oil fume removal device for an integrated kitchen on an offshore platform

technical field

The utility model belongs to the field of offshore platform kitchens, and relates to a fume hood, in particular to a comprehensive oil fume removal device for an integrated kitchen on an offshore platform.

Background technique

Fan equipment is used in the current offshore platform kitchens, and the cooking fume is directly discharged into the atmosphere, causing pollution to the environment. In addition to the central air-conditioning air inlet, there is no independent indoor fresh air supply device. When the exhaust fan is working, the door must be opened, and the aisle air is used to make up for the lack of fresh air.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a comprehensive oil fume removal device for an integrated kitchen on an offshore platform that can make up for the lack of fresh air volume.

The technical solution adopted by the utility model to solve technical problems is:

A comprehensive oil fume removal device for an integrated kitchen on an offshore platform, including an exhaust fan, a cover body, an exhaust pipe assembly and a water tank. The upper water pipe group and the return water pipe group are respectively connected between the water tank and the cover body. Connect the exhaust pipe assembly and the exhaust fan, connect the upper water pipe group of the fan between the exhaust fan and the water tank, install a water separation fan on the upper part of the cover body, and install a mesh filter plate in the cover below the water separation fan. Nozzles are evenly distributed between the mesh filter plate and the water fan, and the lower end of the cover body is parallel to the mesh filter plate and fixed with a water baffle. On the front face of the cover body corresponding to the fresh air inlet duct, a plurality of grille outlets are evenly distributed at intervals, and one end of the fresh air duct is connected to the upper end of the cover body corresponding to the fresh air intake duct, and the other end of the fresh air duct is connected to the inlet air duct. The fresh air fan, the fresh air intake fan and the exhaust fan are all controlled by inverter PLC.

Moreover, a lighting space is separated by a partition at the bottom of the fresh air duct in the cover body, and lighting lamps are embedded in the lighting space.

Moreover, one end of the exhaust pipe assembly is connected to the oven hood through an oven exhaust pipe.

Moreover, one end of the exhaust pipe assembly connected to the exhaust fan is also communicated with and fixedly installed with a spare centrifugal fan.

Advantage and positive effect of the present utility model are:

1. The fresh air duct is integrated in the cover of this device, and the exhaust fan of the oil fume purification system and the fresh air fan are linked to control. When the exhaust air volume of the oil fume purification system is large, the air supply of the fresh air fan will be locally Supplement, in order to avoid the air flow in the kitchen is too fast and cause the effect of the kitchen air conditioning system to weaken or even fail.

2. Compared with the original wind hood, the exhaust air volume of this device is greatly improved. Because of the frequency conversion stepless speed change technology, the exhaust air volume can be changed according to the change of the workload, and the exhaust air efficiency can be improved in the energy-saving mode.

3. This device adds a fresh air fan to send in fresh air in time, so that the pressure in the kitchen tends to be balanced and there is a slight negative pressure.

4. The intake and exhaust fans of this device are all operated under the control of PLC, which not only saves energy, but also adjusts the intake and exhaust air volume to the best ratio.

5. The device has four grille air outlets evenly distributed at intervals on the front face of the cover body, and the change of the air inlet direction can be realized by manually adjusting the direction of the grille.

6. This device adds a variable-speed blower and an air intake duct close to the exhaust fan, so that the intake and exhaust air can be mixed at the upper part of the wind hood. Partial airflow conversion is formed, which not only effectively eliminates oil fume, but also reduces the extraction of air-conditioning airflow.
