Description

Air intake device for combustion engine

Technical Field

The utility model relates to an air inlet unit especially relates to an air inlet unit for combustion engine.

Background

The gas turbine is provided with an air inlet device which comprises a filter, the purpose of the filter is to purify air, and if the air quality is poor and the dust is more, the filter needs to be replaced so as to ensure that the equipment can normally operate. The existing filter adopts a plurality of plate-type filtering units, the filtering area is limited, if the filtering cannot meet certain requirements, the plate-type filtering units need to be replaced, so that the filtering units need to be replaced frequently, the material cost is increased, and the labor cost is increased; meanwhile, steel structure frames are needed for installing the plate-type filtering units, the steel structure frames are crossed transversely and vertically, the number is large, and the frame cost is high.

The above is the deficiency of the prior art.

Disclosure of Invention

The technical problem to be solved by the utility model is to provide an air inlet unit for combustion engine, can reduce filter unit's change frequency, reduce steel structure frame, reduce cost.

The technical scheme of the utility model is that: the utility model provides an air inlet unit for combustion engine, is including air-purifying's filtering component, shrink section and elbow, the bottom at the shrink section is connected to the elbow, the air after the filtering component purifies is in shrink section direction elbow, filtering component comprises roll curtain formula filter unit and support.

A silencer is arranged between the filtering component and the contraction section.

A canopy is arranged in front of the filtering component.

The roller shutter type filtering unit is mainly used for purifying air, is generally used at a civil opening and cannot move. The utility model adopts the rolling screen type filtering unit, utilizes the filter material with the roll, when the filter material in use is not satisfied with the requirement, the filter material can be rolled up through electric control or manual control, the clean filter material can be continuously used at the position of the original filter material, the filter plate can not be replaced like plate-type filtering, and the times of replacing the filtering unit are greatly reduced; simultaneously, because the plate filter needs more metal framework of violently erecting, and the utility model discloses a roll up curtain formula filter unit, avoided a large amount of metal framework's use, can practice thrift the skeleton cost.

Third, roll up curtain formula filter unit can be conveniently installed inside the filtering component, can hoist and mount and transport together, is favorable to rolling up curtain formula filter's dismantlement and transportation.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1-3, the utility model discloses an air inlet unit for gas turbine, its constitution includes: canopy 1, filtering component 2, silencer 3, constriction section 4 and elbow 5. The rain shed 1 has the main function of preventing rainwater from entering the filter 2; the filter component 2 mainly has the functions of filtering air and purifying the air; the muffler 3 mainly functions to reduce noise; the contraction section 4 has the main function of enabling air flow to uniformly enter the elbow; the main function of the elbow 5 is to change the direction of the air flow.

The filtering component 2 comprises the following components: a rolling shutter type filter unit 7, which has a main function of filtering air, and a filter holder 6, which has a main function of supporting the rolling shutter type filter.

The invention uses rolling curtain filter to replace the conventional plate filter unit, and reduces the replacement times of the filter unit. The roll up curtain formula filter in the past is used inside civil engineering entrance to a cave usually, this is to roll up the curtain formula and install inside air intake filter assembly, can make roll up curtain formula filter dismantlement convenient, can make simultaneously form a whole, hoists the transportation together. And the steel structure frame is saved, and the material cost and the labor cost are saved.

The utility model discloses an air intake system with can dismantle curtain formula filter rolls up, the main function can reduce filter unit's change number of times, reduce cost.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
