CN2178139Y - Wall membrane type reaction absorbing device - Google Patents

Abstract

The utility model relates to a wall membrane type reaction absorbing device which is chemical equipment for gas and liquid reaction absorption. The wall membrane type reaction absorbing device is suitable for a gas and liquid reaction system in chemical industry and an effluent gas treating system for environmental protection. The utility model is composed of a spray head, a flange, a main pipe, a layer baffle plate, an outer sleeve pipe and a bottom cover, wherein, an outlet is arranged on the bottom cover, and spraying holes in the spray head are all arranged around the spray head, and a plurality of overflow ports are arranged on the periphery of the main pipe connected with one end of the layer baffle plate. The device is a multilayer combined body combining a side spray type with inclined plane overflow to cause liquid phase to flow through layers one by one in the form of a liquid film and to cause gas phase to pass through in the form of turbulent flow motion. The utility model is characterized in that pressure and resistance in the device is little, the contact time of the gas phase and the liquid phase is long, the reaction is sufficient, and the effect of absorption is favorable.

Description

Wall membrane type reaction absorbing device

Wall film type reaction absorption plant relates to chemical field, is the chemical industry equipment that a kind of gas liquid reaction absorbs, and is applicable to chemical industry gas liquid reaction system and environmental protection exhaust treatment system.

Present gas-liquid reaction equipment mainly contains retort, is provided with sieve plate in jar and makes gas phase dispersion pass through liquid layer; Absorption equipment has surface absorber, spray absorber, bubbling absorber four classes, all these equipment, and gas phase all enters from the bottom, or because fluid-tight (fillings) system pressure, resistance are big, or just the surface contacts, and inadequate problem all responds.

The purpose of this utility model is to provide another gas liquid reaction absorption equipment, and its system's internal pressure and resistance reduce, and can not use powerful air draft aerating apparatus; It has increased the time of contact of gas-liquid two-phase, thereby gas liquid reaction is abundant, absorbs fully.

The purpose of this utility model is achieved in that wall film type reaction absorption plant is made of shower nozzle, flange, the person in charge, layer baffle plate, outer tube and bottom, and outlet is arranged on the bottom; Shower nozzle is positioned at the top of device, and the spray orifice on the shower nozzle all is arranged on four sides of shower nozzle; The person in charge has three sections at least, and they are positioned on the same axis, and every the layer baffle plate that is equipped with dish type, the outer tube that is provided with the band inclined-plane combines as a whole the two neighboring sections person in charge between per two sections persons in charge, and every section person in charge is provided with a plurality of overfalls with layer periphery of baffle plate termination.

Device of the present utility model is a kind of multiple layer combination body, gas-liquid two-phase is all gone into the top and is entered, be responsible for and be interior pipe, each section person in charge is separated by layer baffle plate, overfall on the person in charge and layer baffle plate are had the outer tube on inclined-plane and are sealed, this is that a kind of employing lateral spray type and inclined-plane and overflow combine, and liquid phase is successively flow through, the device that gas phase is then passed through with eddy current turbulent fluctuation form with the attached wall of liquid film form.

Characteristics of the present utility model are: device internal pressure and resistance are little, can use low power air draft aerating apparatus, and gas-liquid two-phase all enters from the top, and time of contact is long, sufficient reacting, good absorbing effect.

Embodiment further specifies below in conjunction with accompanying drawing.

Accompanying drawing is a structural representation of the present utility model.

Among the figure: 1-shower nozzle 2-flange 3-is responsible for the 4-overfall

5-layer baffle plate 6-outer tube 7-bottom 8-outlet

Arrow---expression gas phase inlet

Embodiment, referring to accompanying drawing, this is to adopt three sections the utility model application examples of being responsible for two-layer combination, and this device is used for handling the influence of the acid mist in laboratory to environment, predominant tube diameter 150mm, bulking block all is that igelite is made, the adapted blast is not more than the exhaust equipment of 5Pa, only needs to keep the pH value of liquid phase to be not less than 8, and liquid phase can be used repeatedly, liquid phase is heavy clear limewash, and the acid mist absorptivity can reach 100%.

Claims (1)

1. Wall film type reaction absorption plant is made of shower nozzle 1, flange 2, the person in charge 3, layer baffle plate 5, outer tube 6 and bottom 7, and outlet 8 is arranged on the bottom, and it is characterized in that: shower nozzle is positioned at the top of device, and the spray orifice on the shower nozzle all is arranged on four sides of shower nozzle; The person in charge has three sections at least, and they are positioned on the same axis, and every the layer baffle plate that is equipped with dish type, the outer tube that is provided with the band inclined-plane combines as a whole the two neighboring sections person in charge between per two sections persons in charge, and every section person in charge is provided with a plurality of overfalls 4 with layer periphery of baffle plate termination.
