Abstract
The utility model relates to a dust removal system for hot-dip galvanized steel pipe production, which is characterized by comprising a plurality of cloth bag dust removal devices respectively composed of a cloth bag dust removal chamber, a back flushing device and a zinc powder recovery container, the cloth bag dust removal chambers are in parallel connection, inlets of the cloth bag dust removal chambers are connected with a steam heating furnace through a steam pipeline, gas after dust removal is discharged from an outlet of each cloth bag dust removal chamber through an output pipeline, a plurality of cloth bags are perpendicularly arranged in each cloth bag dust removal chamber at intervals, an opening and closing baffle and one zinc powder recovery container are arranged at the lower end of each cloth bag dust removal chamber, heating and heat insulation devices are arranged around the bag cloth dust removal chambers, each back flushing device is mounted above the corresponding cloth bags, a sprayer of each back flushing device is aligned to cloth bag openings, and the back flushing devices are connected with a contactless pulse control meter for controlling operation of the same. The dust removal system for hot-dip galvanized steel pipe production is reasonable in design and capable of effectively recovering zinc powder in the zinc powder gas so that energy is saved, environment is protected and production cost is reduced, and has the advantages of high zinc powder recovery rate, stability in running, simplicity in operation and the like.
Description
Technical field
The utility model belongs to the hot galvanized steel pipe field, especially a kind of dust pelletizing system that is used for hot galvanized steel pipe production.
Background technology
At present, in the hot galvanized steel pipe production process, utilize steam pipe oven to produce steam to after blowing inside and outside the steel tube hot galvanizing, the steam that has zinc powder can be discharged in the atmosphere, contaminated air not only, and make a large amount of zinc powders slattern in vain.Though can use common sack cleaner to carry out dedusting,, because of water content in the steam bigger; Cause the zinc powder gas contained humidity that gets in the sack cleaner more, when cloth bag filtration zinc powder, be prone to adhere to zinc powder; Stop up passage, and make the dust that is reclaimed be the mud shape, the dust removal by filtration weak effect; Zinc fume is assembled on cloth bag too much in addition, and the effect that makes dust removing effects and zinc powder reclaim is relatively poor, causes air pollution and be difficult to reduce production costs.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and the dust pelletizing system that hot galvanized steel pipe is produced that is used for of a kind of zinc powder rate of recovery height, good dedusting effect is provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of dust pelletizing system that is used for hot galvanized steel pipe production; Comprise a plurality of bag-type dust collectors that constitute by bag-type dust chamber, back-blowing device and zinc powder returnable; The bag-type dust chamber is connected in parallel; The inlet of bag-type dust chamber is connected with steam pipe oven through jet chimney, and the outlet of bag-type dust chamber is discharged through the gas of output channel after with dedusting, vertically is provided with a plurality of cloth bags at the bag-type dust partition; Be provided with switch baffle plate and zinc powder returnable in the lower end of bag-type dust chamber; Be provided with heating and heat-insulating device around in the bag-type dust chamber, back-blowing device is installed in the top of cloth bag and makes the nozzle alignment cloth sack of back-blowing device, and back-blowing device also is connected with the contactless pulse control instrument of its work of control.
And described cloth bag adopts the terylene Nomex as the cloth bag material.
The advantage and the good effect of the utility model are:
The utility model carries out zinc powder through a plurality of bag-type dust collectors of parallel connection to zinc powder gas and reclaims and dedusting; The rate of recovery of zinc powder has increased more than 10% than existing dust arrester; Reclaim the zinc powder in the zinc powder gas effectively, practiced thrift the energy, reduced production cost; Simultaneously, avoid zinc powder gas to spread, jeopardize the problem of health without filtration, protected environment, have the zinc powder rate of recovery, characteristics such as stable and simple to operate.
Description of drawings
Fig. 1 is that the system of the utility model connects sketch map.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done further detailed description:
A kind of dust pelletizing system that is used for hot galvanized steel pipe production; As shown in Figure 1, comprise a plurality of bag-type dust collectors that constitute by bag-type dust chamber, back-blowing device and zinc powder returnable, the bag-type dust chamber is connected in parallel; The inlet of bag-type dust chamber is connected with steam pipe oven through jet chimney; The outlet of bag-type dust chamber is discharged through the gas of output channel after with dedusting, vertically is provided with a plurality of cloth bags at the bag-type dust partition, is provided with switch baffle plate and zinc powder returnable in the lower end of bag-type dust chamber; Be provided with heating and heat-insulating device to keep the dedusting constant indoor temperature around in the bag-type dust chamber; Prevent to contact between dust arrester and cold air and form dewfall, above the bag-type dust chamber, back-blowing device is installed, the nozzle alignment cloth sack of back-blowing device; Back-blowing device also is connected with the contactless pulse control instrument of its work of control, is started by contactless pulse control instrument timing controlled back-blowing device.Dust arrester can be parallelly connected a plurality of, and in the present embodiment, the dust arrester of parallel connection is 4; Cloth bag adopts the terylene Nomex to do the cloth bag material, and this material has enough intensity, Air permenbility and heat resistance.
The operation principle of the utility model is: steam pipe oven carries out steel tube hot galvanizing; The zinc powder gas that is produced blows to the indoor bottom of bag-type dust through jet chimney; Zinc powder receives cloth bag and stops and be adsorbed in the cloth bag outside that gas then gets into the upper end and gets into the final dusting device through output channel through cloth bag.Dust outside cloth bag is cumulative; The Air permenbility of cloth bag is reduced, and the pressure of bottom, bag-type dust chamber is when increasing with respect to top, cloth bag just caves in; When cloth bag caves in to a certain degree; Jet in cloth bag by contact pulse control instrument control back-blowing device through nozzle, cloth bag is outwards risen, and get through the passage of cloth bag.Thus, the zinc powder in the cloth bag outside is trembled bottom, bag-type dust chamber, open the switch baffle plate and flow in the zinc powder returnable through the suction effect of rising of cloth bag.
It is emphasized that; The described embodiment of the utility model is illustrative; Rather than it is determinate; Therefore the utility model is not limited to the embodiment described in the specific embodiment, every by those skilled in the art according to other embodiments that the technical scheme of the utility model draws, belong to the scope of the utility model protection equally.
