Abstract
The utility model relates to a dust removing device, and in particular relates to a smoke and dust settling chamber used for a heat exchanger of a hot blast furnace. The smoke and dust settling chamber comprises a heat exchange chamber and multiple settling chambers, wherein the heat exchange chamber is divided into multiple heat exchange zones by virtue of a first baffle wall and a second baffle wall, one end of the heat exchange chamber is communicated with an air inlet, the other end of the heat exchanger chamber is communicated with an air outlet, and the two adjacent heat exchange zones are alternately communicated by virtue of the settling chambers and a notch of the second baffle wall; and the settling chambers are arranged below the heat exchange zones, and the multiple settling chambers are separated from each other by virtue of the second baffle wall. The smoke and dust settling chamber used for the heat exchanger of the hot blast furnace, disclosed by the utility model, integrates two equipment parts, namely a gravity settling chamber and a heat exchanger shell, into a whole, has a simple structure and small occupied area, saves equipment space and is convenient to mount and use; smoke is settled by two times in the smoke and dust settling chamber used for the heat exchanger of the hot blast furnace, dust collection efficiency is effectively improved, and a relatively good dust removing effect is realized; and stepped reduction of dust in the smoke reduces abrasion to equipment, and service life of the equipment is prolonged.
Description
Technical field
The utility model relates to a kind of cleaner, especially a kind of depositing dust smoke-box that is used for the hot-blast stove heat exchanger.
Background technology
Prior dedusting equipment only is used for the equipment separated dust from air-flow, its objective is Purge gas, reclaims valuables, protection environment and recycle the energy etc., but its action effect is single.Prior dedusting equipment comprises dry-type dedusting equipment and wet-scrubbing equipment.The dry-type dedusting equipment height is bigger, difficult arrangement, and normal discovery has water phenomenon in actual motion; And wet-scrubbing equipment is applicable to high pressure, and the sewage sludge of discharge needs to handle, and the washings of clarification should repeat reuse, also are prone to cause equipment and Corrosion of Pipeline, have increased cost.Dry-type dedusting equipment comprises gravity settling chamber, inertial dust separator, cyclone dust collectors, electric cleaner and bag filter etc.Wherein gravity settling chamber is to make in the dust-contained airflow grit natural subsidence and make its a kind of cleaner separated from the gas by gravity, also is dust-settling compartment, dust chamber; Its action principle is: after dusty gas got into gravity settling chamber, because of flow area enlarges the flow velocity that slows down, if at the bottom of gas can be reduced to the chamber through the time endoparticle of gravity settling chamber, particle just can be separated from air-flow.
The high-temperature flue gas of existing hot-blast stove also needs through the cleaner dedusting behind heat exchanger, and floor space is big, equipment cost is high, and particle varies in the dust, and dedusting is wayward, therefore needs to adopt multistage dedusting; The first order often adopts gravity settling chamber to remove the dust of larger particles.Existing gravity settling chamber floor space is big, efficiency of dust collection is low, and the general only suitable above coarse dust of 50～100 μ m that captures is as the first order in the multistage dedusting; And flue gas leads directly to into equipment, and the frequent flush equipment of flue gas that contains dust can cause wearing and tearing, causes the lost of life of equipment.
The utility model content
The technical problem that the utility model will solve is: existing gravity settling chamber action effect is single, the expansion chamber floor space is big, efficiency of dust collection is low in order to solve; And be prone to cause the technical problem that equipment attrition influences service life of equipment, the utility model provides a kind of depositing dust smoke-box that is used for the hot-blast stove heat exchanger.
The utility model solves the technical scheme that its technical problem adopted: this depositing dust smoke-box that is used for the hot-blast stove heat exchanger comprises Heat Room and a plurality of expansion chamber; Said Heat Room alternately is separated into a plurality of heat transfer zone through first deflected current wall and second deflected current wall; One end of Heat Room is communicated with air inlet; The other end of Heat Room is communicated with the gas outlet, and adjacent two said heat transfer zone alternately are communicated with through the breach of the expansion chamber and second deflected current wall; Said expansion chamber is located at the below of heat transfer zone, and a plurality of expansion chambers separate through second deflected current wall.Like this, this depositing dust smoke-box that is used for the hot-blast stove heat exchanger carries out the sedimentation dedusting to gravity settling chamber and the integrated structure of heat exchanger shell when high-temperature flue gas conducts heat; Simple in structure; Floor space is little, has saved the device space, is convenient to install and use; Flue gas has carried out twice sedimentation in this is used for the depositing dust smoke-box of hot-blast stove heat exchanger, improved dust-collecting efficiency effectively, has dust removing effects preferably; The staged of dust reduces and has reduced the wearing and tearing to equipment in the flue gas, has prolonged the service life of equipment.
Regularly the dust stratification of sedimentation is cleared up respectively for ease, had cleaning door on the sidewall of each expansion chamber.
The beneficial effect of the utility model is: these depositing dust smoke-box collection gravity settling chamber and two parts of appliance of heat exchanger shell that are used for the hot-blast stove heat exchanger are one, and simple in structure, floor space is little, has saved the device space, are convenient to install and use; Flue gas has carried out twice sedimentation in this is used for the depositing dust smoke-box of hot-blast stove heat exchanger, improved dust-collecting efficiency effectively, has dust removing effects preferably; The staged of dust reduces and has reduced the wearing and tearing to equipment in the flue gas, has prolonged the service life of equipment.
