Abstract
The invention relates to a chimney smoke filtering cover simple to install and filled with an efficient adsorbent and catalyst. The whole structure of the cover is a trapezoid cylindrical smoke filtering cover composed of eight smoke filtering sheets made of a corrosion resistant material, the eight smoke filtering sheets are waveform in shape and point at eight directions respectively, the smoke filtering sheets are spaced through smoke discharge holes, each of the surfaces of each of the smoke filtering sheets is provided with smoke filtering holes, and each of the smoke filtering sheets is filled with the particular efficient and catalyst. The bottom of the smoke filtering cover is provided with a chimney inner wall fixing ring, four outer wall fixing sheets and four screws. When the cover is used, the cover is sleeved outside a chimney smoke outlet, the inner wall of the mouth of a chimney is clamped by the inner wall fixing ring at the bottom of the smoke filtering cover, and the outer wall of the mouth of the chimney is fixed by screwing the screws of the outer wall fixing sheets to complete the installation of the cover. The chimney smoke filtering cover enables smoke to be discharged from a top opening and eight smoke discharging holes, and the smoke enters the gas filtering sheets through the gas filtering holes to be adsorbed and purified, so the concentration of harmful substances discharged to the atmosphere is reduced.
Description
Technical field
The present invention is a kind of device that chimney smoke filters that relates to, especially can easy installation and fill the chimney air filter cover of high-efficiency adsorbent and catalyst.
Background technology
At present, air pollution be one be badly in need of administer problem, the flue gas that the chimney of coal-fired enterprise discharges is one of important pollution sources, and in flue gas pollutant taking sulfur and nitrogen oxides as main.These enterprises mainly adopt desulfur technology for discharged smoke gas treatment.Desulfur technology needs by building flue, and a series of flue-gas desulfurizing engineerings such as desulfuration absorbing tower complete.But because making the flue gas entering in atmosphere through desulfurization processing, the problem of desulfurization degree and the suffered burn-in effects of long-term use of these engineering equipments appoint so with certain sulfur and nitrogen oxides.Need enterprise to administer and improve even transformation existing system in order further to improve again to the clean-up effect of flue gas, because thereby the complicated of engineering and the cost that greatly increased enterprise make enterprise not high to the enthusiasm of this work, finally cause discharged flue gas still air quality to be polluted.
Summary of the invention
For overcome existing coal-fired enterprise after desulfurizing and purifying is processed institute's flue gas that discharge still to the to a certain degree problem of pollution of air quality existence, chimney air filter cover provided by the invention can not only carry out again filtration, purification and dismounting easy and can not increase expensive before flue gas pollutant enters Atmospheric Diffusion.
The technical solution adopted for the present invention to solve the technical problems is: overall structure is mainly the trapezoidal cylinder shape air filter cover that eight air filter pieces that resistant material makes form, eight air filter pieces are waveform and point to respectively eight directions, spaced apart by fume emission mouth institute respectively between air filter piece, each face of every air filter piece is the filter pore as air filter piece by hollow out all, and in every air filter piece, all loads full granular high-efficiency adsorbent and catalyst.Air filter cover bottom is inner wall of stack retainer plate and four outer wall stators and screw.When use, be sleeved on chimney emission mouth place, block throat inwall by the inwall retainer plate of air filter cover bottom, then the screw that screws outer wall stator fixes throat outer wall and can complete installation.Chimney air filter cover is discharged fume by top end opening and eight fume emission mouths, and the cigarette of discharge fully contacts with high-efficiency adsorbent and catalyst in air filter piece by filter pore, makes like this flue gas before Atmospheric Diffusion, be cleaned again and reduce harmful substance entering.Being reached to exceed by its simple structure and easy installation increases enterprise governance cost, administers air-polluting object thereby impel it to play an active part in.
The invention has the beneficial effects as follows, trapezoidal cylinder shape is up-narrow and down-wide covers flue gas that chimney discharges, it is fully contacted with flue gas, fume emission mouth between air filter cover top end opening and air filter piece can ensure not hinder again chimney emission, and good permeability can also reduce the wind-force that the air filter cover that is arranged on chimney bears.Air filter piece is waveform, has the full adsorbent of filter pore and inner filling and catalyst to be graininess and can make itself and flue gas increase contact area, to reach absorption and catalytic purification effect more fully on each face of air filter piece.Air filter piece points to respectively eight directions and can make because the flue gas that wind-force effect is discharged from any one fume emission mouth can be in contact with it.Filter pore except can make flue gas by can also make air filter piece rainwater can leached and can not hoard at once after rain drop erosion.Thereby chimney air filter cover is exceeded increase cost by its simple structure and easy installation, so that the universal use of chimney smoke filter.

Detailed description of the invention
In shown in Fig. 1, Fig. 2, the trapezoidal cylinder shape air filter cover that overall structure forms for eight air filter pieces (1), air filter piece (1) is waveform and spaced apart by fume emission mouth (6) institute and point to eight directions respectively.Flue gas is in the time discharging by fume emission mouth (6), through inner side filter pore (2), outside filter pore (3), upper end filter pore (4), lower end filter pore (10) and side filter pore (5) enter air filter piece (1), react with the adsorbent and the catalyst granules that load in air filter piece (1), thereby flue gas is purified again being discharged into before Atmospheric Diffusion.
As shown in Figure 3, whole chimney air filter cover is sleeved on chimney (11) exhaust opening, inwall retainer plate (7) by air filter cover bottom blocks chimney (11) exhaust opening inwall, then screws screw (9) on every outer wall stator (8) and fix chimney (11) exhaust opening outer wall and can complete installation.
