The present invention relates to an improved water pipe comprising a chamber containing water in its lower portion, its upper compact cylindrical portion serving as a smoke collection reservoir; a bowl for combusting tobacco or medicinal herbs, the smoke directed through a tube to the water chamber below the water; and a mouth piece for applying suction to the interior of the chamber to inhale the smoke.

A filtration system for use in connection with a central vacuum system in a hospital or other medical facility. In certain aspects, the filtration system comprises a removable filter for removing contaminants; a fitting adapted for connection to a central vacuum source/system which provides constant suction, which fitting is positioned between the filter and the central vacuum source; a flow control valve positioned between the filter and the fitting; wherein the relative positions of the fitting, flow valve and filter prevent contaminants from being discharged into the central vacuum system. In other aspects, the system provides variable filter life based upon variable flow.

Provided is a filter unit, including a frame fixed along a perimeter of an opening in a wall, a housing connected to the frame to form an inner space, a cover plate installed on the frame to cover the inner space, and a filter box provided with a filter and installed in the inner space.

Disclosed is an air purifier, which comprises a shell with an air inlet and an air outlet, an ecological purification system with a flowerpot assembly, a microorganism box and a water tank arranged in sequence, a filtering system, and a control system for carrying out control. The water of the ecological purification system flows through the filtering system to bring dust and VOCs adsorbed by the filtering system into the ecological purification system for purification. The flowerpot assembly comprises a flowerpot. The water of the water tank enters the flowerpot via a water inlet, and when the water level is higher than a water outlet, the water flows through the microorganism box and then enters the water tank, so as to form the water circulation. The air purifier is simple in structure, easy to operate and low in cost, and has a high purification efficiency for air pollutants, especially VOCs.

An exhaust unit includes a dirty air intake opening, a clean air output opening and an airflow path defined between the dirty air intake opening and the clean air output opening. The exhaust unit further includes an upstream quenching section and a downstream filtering section along the airflow path. The quenching section has a wetting chamber that includes a reservoir having a fill level for a quenching liquid, and a downtube connected over the dirty air intake opening and opening at its end above, and in opposition to, the plane of the fill level.

The present invention is a portable air purifier device intended to be attached to the belt or to the neck of a user. Purified air is generated by electrochemically and magnetically treating a polluted air. Polluted air is forced through an ionized water, which absorbs particles and kills possible air born bacteria. A magnetic filter assures that small metal particles are also separated from the polluted air. The purified air is then delivered towards the face of the user either through an air curtain or through a mask.

A system and method for clean and low-carbon in-situ disposal of waste incineration fly ash includes a waste incineration system and a fly ash disposal system. The fly ash disposal system includes a water washing system, an MVR system, and a dioxin removal system. The water washing system includes a water washing device and a press filtering device. The dioxin removal system includes a heating device, an activated carbon adsorption device, and a heat pump system. The MVR system includes a crystallizer, a heater, a vapor compressor, and other equipment. The waste incineration system is coupled with the fly ash disposal system nearby to achieve in-situ disposal of fly ash, avoiding the logistics cost and secondary pollution problems of long-distance transportation of fly ash, and greatly reducing energy and water resource consumption.

An exhaust purification system has a centrifuge filter, a first fan device, a second fan device, a pump, and an ozone generator. The centrifuge filter has a container having a waste gas treating area and a wastewater treating area. The first fan device communicates with and draws gas into the waste gas treating area. The second fan device communicates with and draws the gas out of the waste gas treating area. The pump communicates with and draws wastewater from the wastewater treating area. The ozone generator communicates with the pump and introduces ozone into the wastewater inside the pump. A part of the ozone dissolved in the wastewater is released to the waste gas treating area to react with the gas, and the other part of the ozone dissolved in the wastewater reacts with the wastewater.

A system for relocating polluted air includes a tubular chamber with an inlet at one end, an outlet at a end, and auxiliary venturi inlets between the inlet and the outlet. There is at least one fan arranged within the tubular chamber. The fan flows air from outside of the tubular chamber, through the tubular chamber and out of the tubular chamber through the outlet. A compression chamber compresses air before entering the heating chamber. There is at least one heating element within the heating chamber. The heating element(s) heat the air, thereby increasing the velocity of the air through the tubular chamber. The air exits the tubular chamber through the outlet, directed vertically and upward towards upper strata of the atmosphere to redirect the air (and pollutants) into the upper strata of the atmosphere. In some embodiments, filters and scrubbers are provided within the tubular chamber for reducing pollutants.
