Abstract
The invention relates to a falling film absorbing device, which comprises a falling film absorber, a chemical reaction tower, a condensing tower, a tail gas tower and an ejector pump, wherein the top of the chemical reaction tower is connected with the top of the condensing tower by a pipeline; a water inlet is formed at the upper part of the condensing tower; a water outlet is formed at the lower part of the condensing tower; the water inlet is connected with a water diversion pipeline in the condensing tower; the water diversion pipeline is connected with a spray head; the bottom of the condensing tower is connected with the falling film absorber by a pipeline; the top of the falling film absorber is connected with the side wall at the bottom of the tail gas tower by a U-shaped pipe; the side wall at the bottom of the falling film absorber is connected with the bottom of the tail gas tower by a pipeline; the tail gas tower is filled with a chemical packing layer; a spray pipe is arranged in the tail gas tower above the chemical packing layer; the top of the tail gas tower is connected with the ejector pump by a pipeline; a water inlet pipe is arranged at the top of the ejector pump; and the bottom of the ejector pump is connected with a drain tank. The falling film absorbing device has the advantages that the device constitutes a complete absorbing system, the falling film absorber and the tail gas tower conduct double absorption and waste removal, and the absorption is more thorough.
Description
Technical field
The present invention relates to the falling film absorption device.
Background technology
Corrosive gas such as hydrogen chloride that in reaction, discharges or sulfur dioxide need absorb processing, both can protect environment, can reclaim industrial chemicals again to utilize again, and at present residual waste gas often adopts pickling, alkali cleaning to absorb or reclaims in the chemical reaction.Common employing absorption tower absorbs, and adopts multilayer column plate hierarchical processing to accomplish absorbing and filtering mostly, and the structure more complicated does not have complete systematicness, and equipment cost is higher; Usually in the process of handling waste gas, can produce certain waste water, if untimely recycling then causes the waste of water resource.Therefore, need provide a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this invention is to provide that a kind of systematicness is strong, the falling-film absorber of good absorbing effect.
The technical solution adopted for the present invention to solve the technical problems is:
The falling film absorption device comprises falling-film absorber, and it also comprises chemical reaction tower, condensing tower, tail gas tower and jet pump; Said chemical reaction top of tower is connected with the condensing tower top through pipeline, and said condensing tower top has water inlet, and said condensing tower bottom has delivery port; Said water inlet is connected with the interior conduit pipe of condensing tower; Said conduit pipe is connected with shower nozzle, and said condensing tower bottom is connected with falling-film absorber through pipeline, and said falling-film absorber top is connected with the tail gas tower side walls through U type pipe; Said falling-film absorber side walls is connected with the tail gas tower bottom through pipeline; Be filled with chemical packing layer in the said tail gas tower, be provided with shower in the tail gas tower of said chemical packing layer top, said tail gas tower top is connected with jet pump through pipeline; Said jet pump top is provided with water inlet pipe, and said jet pump bottom is connected with lower flume.
Said lower flume is connected with the condensing tower bottom through pipeline.
Said falling-film absorber bottom is connected with the finished product jar.
The invention has the beneficial effects as follows: this device comprises falling-film absorber, chemical reaction tower, condensing tower, tail gas tower and jet pump, and it has formed a complete absorption system, and falling-film absorber and tail gas tower carry out dual absorption except that useless, and be effective, absorbs more thorough.
