Abstract

The utility model is mainly used for industrial dust in various shapes, kilns, stoves for boiling tea water and boilers and has the functions of high efficiency reaction for absorbing harmful gases in smoke gases. The utility model is composed of an inlet, a gas box, a gas separating opening, an automatic settling box, a multiple machine tube, an X path, a circulation plate, a liquid blocking plate, a gas passage, an outlet, a water supply box, a flushing tube, etc. In fact, the utility model uses the multiple machine tube, the X path and the circulation plate to form vacuum high density filtering and complete secondary reaction absorption. The utility model performs the functions of high efficiency reaction and absorption for removed smoke, sulfur and nitrogen and other harmful substances. The utility model has the advantages of little resistance, little water consumption and little electricity consumption; the dust removing efficiency is 99.9%, and various indexes of the treated smoke are below the state-specified standards.

Description

Multimachine tubular type efficiently smoke desulfurization removing nitric absorber

Multimachine tubular type efficiently smoke desulfurization removing nitric absorber described in the utility model relates on the industrial dust, stove, tea furnace, boiler of multiple shape in the environmental protection, and the pernicious gas in the flue gas is had the highly effective reaction absorption.Belong to the environmental protection equipment in the atmosphere.

At present, the dedusting desulfurizing purifier structure that is used for various flue gases is varied, and the cleaning principle difference is also different with the principle of this structure.As wet scrubber is to have adopted with water slug, atomizing, water-bath etc., and formation water contacts with flue gas, removes dust and pernicious gas, and reaches general dust removing effects.Above-described method is low to the fine dust capturing efficiency, desulfurized effect is poor, because water can not contact with flue gas fully, so do not have the effect of efficiently smoke dust-removal and desulfurizing denitrogenation, although wet cleaner version is different, but its clean-up effect is neither very desirable, is difficult to reach the air standard requirement of national regulation, the pollution also serious to some extent to atmosphere.

The purpose of this utility model is that water is circulated automatically, and water consumption is few, and resistance is little, can economize on electricity has efficiently smoke, dust-removal and desulfurizing, the wet absorption device that denitrification effect is strong.

Description of drawings:

Fig. 1 is a structure chart of the present utility model:

Fig. 2 is the floor map of the A-A of Fig. 1.

Best-of-breed technology scheme of the present utility model: be described in further detail with Fig. 1, Fig. 2: this structure By import, gas cabinet, branch gas port, automatic sedimentation case, multi-machine tube, X passage, circulation plates, gear Liquid plate, gas passage, feed-tank, cleaning hose, deposit the relevant parts such as slag bucket, outlet and form. This The essence of utility model is to adopt multi-machine tube [6] and X passage [5] circulation plates [7] and formed high-accuracy The reaction of degree is filtered, and has finished the second order reaction absorption. To reach high efficiency effect. Divide gas port [3 ] with automatic sedimentation case [4] with deposit slag bucket [13] and finish first order reaction absorption.

The per at least 4 Guan Weiyi units of multi-machine tube [6] have a unit at least in every absorber.It is characterized in that having formed naturally between the tube and tube X-shaped.Constitute by multicomputer and Duo Gen stainless pipe or glass-ceramic diabase pipe.So the shape of passage [5] also is an X-shaped.

The reaction absorption process of this structure is to have gas feed [1] to enter gas cabinet [2] to have gas to divide gas port [3] to enter black smoke SO in automatic sedimentation case [4] pernicious gas again ₂, NO _xContact with liquid and to have carried out the first order reaction absorption.Inner working water level has feed-tank [10] circulation pipe [11] to reconcile automatically, carries out washing reaction.And fine dust and SO in the flue gas ₂, NO _xEnter X passage [5] circulation plates [7] through high wind speed and carried out the filtration of washing at a high speed and high precision, finished the second order reaction absorption.The harmful substance that decomposition is come out has been fallen the moisture content of depositing in slag bucket [13] clean air and has been separated through gas passage [9] and liquid barrier [8], and the clean gas after separating enters air-introduced machine by gas vent [16] and discharges, and puts into atmosphere.

This structure is through having adopted the multimachine tubular structure and having eliminated the pernicious gas agent.Experimental results show that: reactivity is strong, absorptivity is high, the flue gas lingemann blackness reaches the 0-0.6 level, and efficiency of dust collection reaches 99.9%, takes off SO ₂Efficient reaches 98.8%, takes off NO _xEfficient reaches 89.6%.These parameters have been significantly less than state specified standards, have also reached the atmospheric environment of 21st century.The utility model structure mainly is applicable in the gas of harmful substances such as industrial furnace is close, industrial dust, boiler, tea furnace.
