Abstract
The utility model relates to a dust filter which uses wall flow type honeycomb ceramic as a filtering body and is used for eliminating solid particles contained in gas. The utility model comprises a casing 1, a gas pipe 4, an exhaust pipe 5, a backwards blowing pipe 8, a dust collecting box 17 and a necessary explosion-proof device. The utility model is characterized in that at least two layers of ceramic filtering body assemblies 2 are vertically installed from bottom to top along the shaft directions of honeycomb hole channels; inclined dust falling plates 6 are arranged among the layers. The utility model can not only be used for treating the gas containing fly ash in large quantity, but also has good backwards cleaning effect and solves the dust collecting problem. The dust filter can be used for the dust recovery and the control of the industries, such as steel smelting, grinding materials, cement, etc. In particular, the utility model is suitable for the purification of high temperature flue gas.
Description
Technical field
The utility model relates to a kind of dedusting device, relate in particular to a kind of honeycomb ceramic filter of using as filtering bodies, the device that contained solid particle in the gas is removed, can be widely used in smelting iron and steel, dust in the industry such as abrasive material, cement reclaims and administers, and is particularly useful for the purification to high-temperature flue gas.
Background technology
For the dust removal problem of high-temperature flue gas, the someone has proposed certain methods, has designed some dedusters.As with the deduster of micropore ceramic tube as filtering bodies, can handle various high-temperature smokes efficiently, and drag losses is less, to take volume big but exist, and is difficult for installing and the shortcoming of maintenance.With the dust arrester of honeycomb ceramic filter as filtering bodies, its dust-cleaning principle is, parallel honeycomb duct is arranged in filtering bodies, adjacent two ends, honeycomb duct replace plug-hole, uniform micropore on the honeycomb wall in honeycomb duct, when dusty gas passed through micropore, dust granules was captured and stays in the duct, reaches the purpose of dedusting.At present, with the dust arrester of honeycomb ceramic filter as filtering bodies, because can overcome with the micropore ceramic tube is the shortcoming of the deduster of filtering bodies, be subjected to researcher's extensive concern, in this class dust arrester,, can be divided into two types according to axial level in honeycomb duct or vertical different installation, a kind of is that the axial level in honeycomb duct is installed, and another kind is the axially vertical installation in honeycomb duct.The axial level in honeycomb duct can be provided with multi-layer honeycomb ceramic filtering body assembly, for example U.S. Patent number from bottom to top when installing more easily: 5,593,471 disclose a kind of " Dust Collecting Apparatus ".Though this device can be realized that the flue gas treating capacity is big, take the little purpose of volume, but because the axial level in the honeycomb duct of filtering bodies is installed, dust after the backwash is stayed in the duct easily, therefore exists backwash effect undesirable, influences the problem of dust removing effects.And the honeycomb duct is axially vertical when installing, though backwash effect is better, but owing to there is the difficult problem of dust collection, the dust arrester of individual layer honeycomb ceramic filter body assembly has only appearred being provided with at present, the flue gas treating capacity of this device is restricted, and is not suitable for the occasion that big exhaust gas volumn is handled.
Summary of the invention
The utility model provides the combination wall-flow type that a kind of flue gas treating capacity is big, backwash effect is good high-temperature dust removing device at the deficiency of existing honeycomb ceramic filter dust removal by filtration device.
A kind of combination honeycomb ceramic filter dust removal by filtration device of the present utility model, comprise housing, admission line, discharge duct, blowback pipeline, case and necessary explosion-protection equipment gather dust, it is characterized in that in housing, being provided with at least two layers of axial vertically arranged wall-flow honeycomb ceramic filter assembly in honeycomb duct from bottom to top, between layer and layer, be provided with the hawk that falls of inclination.
The attached technical characterictic of the utility model is to be provided with grey passage at other each layer wall-flow honeycomb ceramic filter casing side except that top layer.
The utility model reaches and can handle the purpose that contains dusty gas in a large number by several layers combination wall-flow honeycomb ceramic filter assembly is set from bottom to top; The honeycomb duct is axially vertical simultaneously installs, solved the backwash effect problem, and by the hawk that falls of inclination is installed between layer and layer, make dust that backwash gets off under the gravity effect, through the hawk that falls, unpowered ground falls into down one deck automatically, falls the dust collecting of dust arrester foot at last, solve the difficult problem of dust collection, realize goal of the invention.
The utility model can make the dust that blowback falls be difficult for being brought into by air-flow in the honeycomb ceramic filter body again by be provided with grey passage in the bigger place of air velocity, can improve filter efficiency, reduce backwash number of times, energy savings.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing, and the utility model is not limited to following examples certainly.
Embodiment 1
Among Fig. 1, the embodiment shown in Figure 2, the number of plies of described wall-flow honeycomb ceramic filter assembly 2 is designed to four layers, form by four casings arranged side by side 7 for every layer, the wall-flow honeycomb ceramic filter 12 that axially vertically put in the honeycomb duct is installed in the casing, the lower box concordant with honeycomb ceramic filter body 12 air inlets opens wide, and the port of export of top isolated cellular ceramic filtering body 12 has certain distance; Be provided with the hawk 6 that falls of inclination between layer and layer, its shape can be surface plate, also can make curved slab, with dividing plate 9 and necessary seal, plays the effect that dusty gas and filter back gas are separated; Be provided with grey passage 11 at other each layer box body 7 sides except that top layer, the grey passage 11 that falls is spaced apart and form by one flat plate 3 and casing 7 sides, the grey passage correspondence 11 about that falls of each layer.
Among Fig. 3, resistance when filtering back gas outflow casing in order to reduce, the instantaneous high pressure that backwash gas stream is formed in upper box is more even, and present embodiment is provided with Taper Pipe 14 in the dead ahead of blowback pipeline 8 gas outlets, and Taper Pipe 14 stretches in the casing on casing 7 tops; The terminal optimal design with the Taper Pipe end in blowback pipeline 8 gas outlets apart from a in 150mm～51mm scope.1 is the upper box maximum inner diameter or the longest length of side, surpasses or less than this scope the maximum pressure in the upper box is reduced, and influences dust removing effects.
Dust arrester installation is positioned at the below of dust arrester housing 1, is connected with the hole 15 of gathering dust that housing 1 is offered, and comprises the sealed valve 16 and the case 17 that gathers dust.
