摘要： A water washed air scrubber in which the contaminated air is first directed toward the surface of a bath of water and cleaning agent at relatively high velocity to create adequate turbulence to achieve a scrubbing action to remove a majority of the contaminate, and thereafter passed through a filter to remove any remaining liquid and/or contaminate.
摘要翻译：一种水洗空气洗涤器，其中污染的空气首先以相对高的速度被引向水浴和清洁剂的表面以产生足够的湍流以实现洗涤作用以除去大部分污染物，然后通过过滤以除去任何剩余的液体和/或污染物。

摘要： An exhaust hood having an inverted V-shaped interior, the walls comprising the inverted V including grease filters and the apex of the inverted V lying adjacent to an exhaust duct to be placed in communication with an exhaust fan. The interior of the hood thus being shaped like an inverted funnel, rising gases and entrained contaminants are directed to the grease filters and thence to the exhaust duct.

摘要： An air ventilation system for cooking equipment having an exhaust hood disposed thereover in a building having a heating-ventilating and air-conditioning system for treating the air in the building. The exhaust hood includes a collection chamber and an exhaust chamber with a filter means mounted therebetween. An exhaust fan draws air loaded with cooking vapors, odors, fumes, smoke and other pollutants collected in the collection chamber through the filter and the exhaust chamber and out through an exhaust passage to the atmosphere. A source of fresh air provides a predetermined amount of fresh makeup air to the collection chamber. A temperature control unit is connected to another source of fresh air, and to the return air duct of the heating-ventilating and air-conditioning system of the building or a room in the building, for providing a combination of fresh air and tempered air to an air curtain passage for forming an air curtain along the front side of the exhaust hood.
摘要翻译：一种用于烹饪设备的通风系统，其具有设置在具有用于处理建筑物中的空气的加热通风和空调系统的建筑物中的排气罩。排气罩包括收集室和排气室，其间安装有过滤装置。排风扇通过过滤器和排气室抽吸收集在收集室中的烹饪蒸汽，气味，烟雾，烟雾和其他污染物的空气，并通过排气通道排入大气。新鲜空气源向收集室提供预定量的新鲜补充空气。温度控制单元连接到另一个新鲜空气源，并连接到建筑物的加热通风和空调系统的回风管道或建筑物的房间，用于提供新鲜空气和回火空气的组合用于沿排气罩的前侧形成气帘的气幕通道。

摘要： An exhaust hood is disclosed which comprises an open underside and a grease filter defining an exhaust plenum between the hood and the grease filter and a flow path through the grease filter. A shutter-like panel is slidable into the flow path adjacent to the grease filter for blocking a portion of the flow path to adjust the distribution of air across the face of the hood without altering the volume of air flowing through the exhaust hood. Multiple side-by-side panels may be provided and each panel preferably tapers in height across its width. An intake fan is provided at a front portion of the hood to direct room air from adjacent the hood through an intake plenum and downwardly at a front portion of the space beneath the hood to create a partial air curtain which is then exhausted through the hood.

摘要： An air ventilation and cleaning system for cooking equipment having an exhaust hood disposed thereover in a building having a heating-ventilating and air-conditioning system for treating the air in the building. The exhaust hood includes a collection chamber and an exhaust chamber with an initial filter means mounted therebetween. An exhaust fan draws air loaded with cooking vapors, odors, fumes, smoke and other pollutants collected in the collection chamber through the filter means and the exhaust chamber, and out through an exhaust passage provided with a water-wash filter and a final filter, and then to the atmosphere. A source of fresh air provides a predetermined amount of fresh makeup air to the collection chamber. A temperature control unit is connected to another source of fresh air, and to the return air duct of the heating-ventilating and air-conditioning system of the building or a room in the building, for providing a combination of fresh air and tempered air to an air curtain passage for forming an air curtain along the front side of the exhaust hood.

摘要： An apparatus and a method for cleaning air carrying smoke, grease, ordors and other pollutants. The air having the grease and other pollutants, such as the exhaust air from a restaurant cooking grill, is passed through a filter box in which is mounted two pairs of planar filter members. The air is passed sequentially in halves through a lower pair of the filter members and then through an upper pair of the filter members and out of the filter box. The filter members are continuously scrubbed by a scrubbing solution comprising cold water and a cold water detergent. The water cools the air and grease in the air is congealed, and it acts as a filter, and it removes the congealed grease from the filter members.
