Technical Field
The utility model belongs to the technical field of the environmental protection equipment, concretely relates to be applied to velocity of flow adjusting device among tube bank defroster.
Background
In the technical field of wet desulphurization, equipment for controlling fog drops and dust at an outlet of a desulphurization tower mainly comprises a flat plate type demister, a ridge type demister, a tube bundle demister, wet electric dust removal and the like, wherein the tube bundle demister has the advantages of high efficiency, low energy consumption, short construction period, no extra land occupation and convenient operation and maintenance, and is widely applied in recent years.
The existing tube bundle demister removes fog drops and dust particles carried in flue gas in the processes of high-speed cyclone, violent mixing and rotary motion of the flue gas through three motion states of agglomeration, catching and annihilation of fly ash particles and fog drops, and the air tower flue gas flow rate which is usually adapted to the design of the existing tube bundle demister is between 2.8m/s and 3.8 m/s.
Receive the restriction that electric wire netting power consumption load and regional power consumption load change are big, most power plant boiler actual operation load change greatly, perhaps there are multiple operating condition in a stove tower and also make the flue gas load change often, and the tube bank defroster often designs as the best operating mode with full load flue gas volume, when the boiler is in the low-load state operation, flue gas velocity of flow through single tube bank is low excessively, the actual flue gas velocity of flow can be less than the empty tower flue gas velocity of flow range 2.8m/s-3.8m/s of current tube bank defroster design many times, this can reduce getting rid of the droplet of tube bank defroster, the dust efficiency value, can image whole desulphurization unit operating stability even.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, an object of the utility model is to provide a can adjust tube bank defroster flue gas velocity of flow, and then ensure tube bank defroster defogging efficiency and whole desulphurization unit operating stability's supplementary adjusting device of tube bank defroster flue gas velocity of flow.
In order to achieve the technical purpose, the utility model adopts the following technical scheme: bundle defroster flue gas velocity of flow auxiliary regulating device lays the admission and exhaust pipeline to the bundle defroster top including many passing the desulfurizing tower wall, is located the desulfurizing tower outside admission and exhaust pipeline is last to be provided with admission valve, discharge valve respectively, is located inside the desulfurizing tower intake and exhaust pipeline is last to be provided with a plurality of branch pipes respectively, the branch pipe corresponds and stretches into in the part tube bank barrel of bundle defroster, the outside parcel expandable or the regulation body of shrink of branch pipe.
Preferably, the adjusting body is an expandable rubber ball.
Preferably, the gas inlet and outlet pipes located outside the desulfurization tower are respectively provided with a safety valve.
Preferably, the air inlet and outlet pipeline passes through the wall of the desulfurizing tower by using a sleeve and is laid above the bundle demister.
Preferably, the air inlet and outlet pipeline is aligned with the central line of the tube bundle cylinder.
Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has at least: make the regulating body of a certain amount aerify through admission valve and inlet and exhaust duct, the regulating body blocks up the tube bank barrel after the inflation, reaches the purpose of enclosure part tube bank barrel to adjusted tube bank defroster flue gas velocity of flow, and then ensured getting rid of dust, droplet efficiency value maximize and whole desulphurization unit operating stability of tube bank defroster. The flue gas velocity adjusting device can realize the adjustment of the flue gas velocity in the tower without stopping production and maintenance through simple electric or manual operation.

Detailed Description
The invention is further explained below with reference to the drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention have been described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
Examples
As shown in fig. 1 to 3, the flue gas flow velocity auxiliary adjusting device of the tube bundle demister comprises a plurality of air inlet and outlet pipes 2 which pass through the wall of the desulfurizing tower by using sleeves and are laid above the tube bundle demister 1, wherein the air inlet and outlet pipes 2 are aligned with the central line of a tube bundle cylinder, and the air inlet and outlet pipes 2 are connected with a compressed air system. In this embodiment, 4 air inlet and outlet pipes 2 are taken as an example, but may be set to other numbers, such as 3 or 5, according to the specification and requirement of the tube bundle demister.
Be located the desulfurizing tower outside advance to be provided with admission valve 3, discharge valve 4 on the exhaust duct 2 respectively, be located inside the desulfurizing tower advance to be provided with a plurality of branch pipes 5 on the exhaust duct 2 respectively, branch pipe 5 corresponds and stretches into in the part tube bundle barrel of tube bank defroster 1, branch pipe 5 outside parcel expandable or the regulation body 6 of shrink, in this embodiment the regulation body 6 adopts expandable rubber ball, can also adopt other collapsible or expanded elastomers of course.
In order to ensure that the pressure in the gas inlet and outlet pipeline does not exceed a set value, safety valves 7 are respectively arranged on the gas inlet and outlet pipeline 2 positioned outside the desulfurizing tower.
The working principle of the utility model is as follows: when the load of the boiler is reduced, the number of tube bundle cylinders to be sealed is calculated according to the current smoke amount, the air inlet valve 3 of the corresponding air inlet and outlet pipeline 2 is opened, compressed air is conveyed into the expandable rubber ball at the position of the branch pipe 5 at the tail end of the pipeline through the air inlet and outlet pipeline 2, after the expandable rubber ball is filled with gas and expands, the air inlet valve 3 is closed, and the expanded rubber ball blocks the tube bundle cylinders, so that the aim of sealing the tube bundle cylinders is fulfilled. When the load of the boiler is increased, the exhaust valve 4 is opened, the gas in the expandable rubber ball is exhausted through the gas inlet and exhaust pipeline 2, the rubber ball is contracted to the minimum state, and the tube bundle cylinder can normally work.
The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
