Description

Dust pelletizing system that msw incineration system used

Technical Field

The utility model belongs to the technical field of waste incineration, and particularly relates to a dust removal system for a waste incineration system.

Background

In the waste incineration operation, the treatment process of the incineration flue gas is an important link, and the treated gas can be discharged only when meeting the waste discharge standard. The process is that the tail gas from boiler burning is first introduced into cooling tower for cooling to meet the requirement of bag type dust removal, and the tail gas is then deacidified and adsorbed by slaked lime and active carbon jetting system before being conveyed to the dust removing system. Because the common incineration flue gas only implements dust and gas separation operation in the dust remover, the work load degree of the filter cloth of the dust remover is higher, the surface of the filter cloth of the dust remover is easily covered with dust after a long time to reduce the performance, but the dust remover has a complex structure and is troublesome to disassemble, and if the dust remover is frequently disassembled and maintained. Instead, the production efficiency of the waste incineration operation is necessarily limited, and therefore, a new technical scheme is needed to solve the problem.

The utility model is implemented by the following technical scheme: a dust removal system for a waste incineration system comprises a dust removal cavity, an ash discharger, a plurality of filter bags, a partition plate, a plurality of venturi tubes, a jet flow pipe and a plurality of baffle plates. The dust removal cavity is of an air container structure, a dust and gas inlet is arranged below the conical bottom of the dust removal cavity, and a purified gas outlet is arranged at the top of the dust removal cavity; the ash discharger is connected and arranged right below the dust remover; the filter bags are arranged in the dust removing cavity at intervals in a parallel mode and are connected with the partition board through the openings of the filter bags, and the partition board is transversely arranged in the dust removing cavity and divides the dust removing cavity into two cavities; the upper opening of each filter bag is provided with the venturi tube which penetrates through the partition plate; the jet pipe penetrates through the side wall of the dust removing cavity, and the horizontal position of the jet pipe is positioned above the partition plate; the baffle plates are arranged in the conical bottom of the dust removal cavity in a transverse staggered interval mode, and each baffle plate penetrates through one slot in the outer wall of the dust removal cavity.

Furthermore, the surface of the baffle plate is attached with plush.

Further, the horizontal position of the dust and air inlet is lower than the baffle plate.

Furthermore, a sealing gasket is arranged at the part, matched with the baffle plate, in the slot.

Further, the ash discharger is connected to the ash discharge system.

The utility model has the beneficial effects that: the device forms a front-end dust-gas separation function by utilizing the baffle plate arrays arranged at the bottom of the dust removal cavity in a staggered mode at intervals, when smoke enters a dust-gas inlet at a low-level position, primary separation between particles and gas is implemented by the baffling separation effect formed by the baffle plate arrays, and the capture rate of dust particles is promoted by the surface lint of the smoke; the smoke after the primary separation is filtered by the filter bag, so that the load of the filter bag on the filter work is effectively reduced, and the service life of the filter bag is prolonged. Meanwhile, when the baffle plate is pulled out, the dust attached to the baffle plate can automatically fall and be collected in the ash discharger through the extrusion of the slot, so that the quick and convenient maintenance measures are realized, and the waste incineration efficiency is guaranteed.

In the figure: 1-a dust removing cavity, 1 a-a dust gas inlet, 1 b-a purified gas outlet, 1 c-a slot, 2-an ash discharger, 3-a filter bag, 4-a partition plate, 5-a venturi tube, 6-a jet pipe and 7-a baffle plate.

Detailed Description

The utility model is described in further detail below with reference to the drawings.

As shown in fig. 1, a dust removal system for a waste incineration system comprises a dust removal cavity 1, an ash discharger 2, a plurality of filter bags 3, a partition plate 4, a plurality of venturis 5, a jet pipe 6 and a plurality of baffle plates 7. The dust removal cavity 1 is of an aerial container structure, a dust and gas inlet 1a is arranged below the conical bottom of the dust removal cavity, and a purified gas outlet 1b is arranged at the top of the dust removal cavity; the ash discharger 2 is connected under the dust remover, and the ash discharger 2 is connected in the ash discharge system; the filter bags 3 are arranged in the dust removing cavity 1 at intervals in a parallel mode, the upper openings of the filter bags are connected with the partition plate 4 together, and the partition plate 4 is transversely arranged in the dust removing cavity 1 and divides the dust removing cavity into two cavities; the upper opening of each filter bag 3 is provided with the venturi tube 5 which penetrates through the partition plate 4; the jet pipe 6 penetrates through the side wall of the dust removing cavity 1, and the horizontal position of the jet pipe is positioned above the partition plate 4; the baffle plates 7 are arranged in the conical bottom of the dust removing cavity 1 in a transverse staggered interval mode, the surface of each baffle plate 7 is attached with plush and penetrates through a slot 1c arranged on the outer wall of the dust removing cavity 1, a sealing gasket is arranged at the part, matched with the baffle plate 7, in the slot 1c, and meanwhile, the horizontal position of a dust air inlet 1a is lower than that of any baffle plate 7.

The working principle of the utility model is as follows:

s1: with this device access incineration system in, after the flue gas after last process through cooling, deacidification, absorption was carried to dust gas entry 1a, through the baffling separation effect that the crisscross interval of bottom set up a plurality of baffling boards 7 formed, the realization is to the separation effect of different proportion mixtures. When solid dust flows upwards, the solid dust is blocked and adhered by the baffle plates 7 due to the inertia of the solid dust and is captured by a large amount of plush on the surface of the plate body, and upward airflow can quickly bypass the baffle plates 7 which are arranged in a staggered way and is conducted to the upper part, so that the dust content of the airflow entering the filter screen to perform filtering operation is greatly reduced; open the inside air current from a left side to the right that produces of jet-propelled pipe 6 simultaneously, make venturi to its inside air current production suction because of the venturi effect, and then drive dirt air current and strain the filter screen and get into space above baffle 4, the gas outgoing after will filtering from net gas export 1b at last to this effectively reduces the work load that the filter screen filters dust and improves its life.

S2: as shown in fig. 2, after a long-term operation, a large amount of dust is accumulated on the surface of the baffle plate 7, and the end of the baffle plate 7 on the outer side is clamped by a tool and is drawn out towards the outer side, in the process, the plate body of the baffle plate 7 and the sealing gasket of the slot 1c are rubbed under the close fit action, so that the scraping action is formed on the dust attached to the surface pile, and meanwhile, the plate body can be repeatedly drawn to promote the dust to be rapidly peeled; the scraped dust just falls into the ash discharger 2 below in the conical inner cavity and is collected, and then is sent into the ash discharge system to be processed, and the baffle plate 7 can be directly inserted for repeated use after being pulled out and completing the dust removal operation, so that the efficient and convenient maintenance effect is realized.

While the utility model has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the utility model is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
