Description

Dust filtering structure of cement kiln superheater

Technical Field

The utility model relates to a cement kiln evaporimeter technical field especially relates to a cement kiln over heater's strain dirt structure.

Background

A cement kiln evaporator, also called a heat pipe evaporator, is a special kiln waste heat recovery device for high-temperature and high-dust kilns such as cement kilns, glass kilns, brick kilns and the like. The main working principle of the cement kiln evaporator is that heat of smoke is collected through the lower portion of a heat pipe, a medium inside the heat pipe rises to a steam drum position after being heated, then the heat is transferred into water inside the steam drum, the water is heated and vaporized, saturated steam is generated for production and living, when the smoke passes through a smoke box, in order to ensure that smoke emission meets requirements, smoke in the smoke needs to be filtered, but at present, a dust filtering structure does not exist, so that the smoke naturally settles by means of resistance of the smoke passing through the smoke box, and the dust filtering efficiency is low.

Disclosure of Invention

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a cement kiln superheater's dirt structure of straining, includes the smoke box, is equipped with flue gas inlet and exhanst gas outlet on the smoke box, and the bottom of smoke box still has dust exhaust funnel, its characterized in that:

at least one group of dust filtering mechanisms is arranged inside the smoke box, each dust filtering mechanism comprises a plurality of groups of dust filtering plates which are distributed in an inclined mode, the dust filtering plates are sequentially arranged from top to bottom and are fixedly connected with the inner wall of the smoke box, and the top ends of the dust filtering plates positioned at the lower part are higher than the bottom ends of the dust filtering plates positioned at the upper part;

and a dust filtering channel which is distributed obliquely is formed between the adjacent dust filtering plates, and one end of the dust filtering channel, which is close to the flue gas inlet, is higher than the other end of the dust filtering channel.

The end part of the dust filtering plate is provided with an end plate which is fixedly connected with the dust filtering plate, and the end plate is positioned on one side of the dust filtering plate and is fixedly connected with the inner wall of the smoke box.

The dust filtering mechanism is positioned at the upper part of the dust discharge funnel.

The dust filter is characterized in that a guide plate is further arranged on the dust filter, the guide plate is obliquely arranged relative to the dust filter, the guide plate is located at the lower portion of the dust filter, the top end of the guide plate is fixedly connected with the dust filter, the bottom end of the guide plate is arranged downwards, and the side face of the front side of the guide plate is arranged towards the direction of a flue gas inlet.

The guide plate is an arc panel, and the intrados of arc panel sets up towards the flue gas import direction.

The utility model has the advantages that: structural design is reasonable, through the setting of dust filter plate, can play the effect of dirt of straining in the smoke box inside for the smoke and dust gathering carries out centralized processing in dust exhaust funnel, wholly has reduced the flue gas dust content of exhanst gas outlet position, has reduced the processing load of terminal environmental protection equipment, and improvement effect is obvious.

Meanwhile, the guide plate is added on the basis of the dust filtering plate, so that the flowing direction of the smoke can be locally changed, the smoke dust in the smoke gas is easier to settle, other smoke gases are impacted downwards, the settlement of the smoke dust in the smoke gas is promoted, and the dust filtering effect is further enhanced.

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic front view of the dust filter plate.

Fig. 3 is a side view of the dust filter plate.

In the figure: 100 smoke boxes, 101 dust exhaust funnels, 200 steam drums, 300 dust filter plates, 301 end plates, 400 guide plates and 401 end plate sections.

Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

As shown in fig. 1 to 3: the embodiment provides a dust filtering structure of a cement kiln superheater, the cement kiln superheater comprises a smoke box 100 and a steam drum 200, the steam drum 200 is positioned at the upper part, the smoke box 100 is positioned at the lower part, and the smoke box and the steam drum are connected through a heat pipe, the heat pipe can transfer the heat of smoke in the smoke box 100 to the water in the steam drum 200 and heat the water; be equipped with gas inlet and exhanst gas outlet on the smoke box 100, gas inlet is located the right side, and gas outlet is located the left side, sets up relatively between the two, keeps the circulation effect of flue gas, still has dust exhaust funnel 101 in the bottom of smoke box 100 simultaneously, and dust exhaust funnel 101 is equipped with two sets ofly for collect the smoke and dust that subsides, and carry out centralized processing to the smoke and dust in the exit position of dust exhaust funnel 101 bottom.

In order to improve the dust filtering effect of the cement kiln superheater, two sets of dust filtering mechanisms are arranged inside the smoke box 100, and the dust filtering mechanisms are respectively positioned on the upper parts of the corresponding dust discharge hoppers 101, wherein:

the dust filtering mechanism comprises four groups of dust filtering plates 300 which are distributed in an inclined mode, the dust filtering plates 300 are sequentially arranged from top to bottom, end plates 301 which are fixedly connected with the end parts of the dust filtering plates 300 are arranged at the end parts of the dust filtering plates 300, the end plates 301 are located on one sides of the dust filtering plates 300 and are fixedly connected with the inner walls of the smoke box 100, the top ends of the dust filtering plates 300 located on the lower portion are higher than the bottom ends of the dust filtering plates 300 located on the upper portion, a staggered distribution effect is formed among the dust filtering plates 300, and smoke is prevented from directly passing through gaps among the dust filtering plates 300;

the dust filtering channels which are distributed obliquely are formed between the adjacent dust filtering plates 300, one end, close to the smoke inlet, of each dust filtering channel is higher than the other end of each dust filtering channel, and when smoke passes through the dust filtering channels, the smoke can be in contact with the bottom surfaces of the dust filtering plates 300, so that the smoke in the smoke is intercepted through physical contact, and the smoke is settled downwards and falls into the dust exhaust funnel 101.

Furthermore, in order to improve the interception effect of the smoke, a plurality of groups of guide plates 400 are further arranged on the dust filtering plate 300, the guide plates 400 are horizontally distributed, the guide plates 400 are obliquely arranged relative to the dust filtering plate 300, the guide plates 400 are arranged at the lower part of the dust filtering plate 300, an end plate section 401 is arranged at the top end of the guide plates 400, the end plate section 401 is arranged in parallel with the dust filtering plate 300 and fixedly connected with the dust filtering plate 300, the bottom end of the guide plates 400 is arranged downwards, the guide plates 400 are arc-shaped panels, inner arc surfaces of the arc-shaped panels are arranged towards the direction of the smoke inlet, due to the oblique distribution effect of the dust filtering plate 300, the guide plates 400 can also be arranged at different heights and can be contacted with the smoke at different heights, and the flow direction of the smoke can be locally changed by virtue of the arc-shaped guide effect, so that the smoke in the smoke is easier to settle, and other smoke is impacted to promote the settlement of the smoke in the smoke, further enhancing the dust filtration effect.

The above is only the preferred embodiment of the present invention, as long as the preferred embodiment is realized by the same means, the objective technical solution of the present invention all belongs to the protection scope of the present invention.
