Abstract
The invention discloses a low-pressure large-capacity fixed flat bag dust removing device of a dust collector, belonging to the technical field of environmental-friendly equipment and relating to pulse jet equipment used together with a bag type dust collector. The low-pressure large-capacity fixed flat bag dust removing device mainly comprises an internal part and an external part, wherein one end of each dust removing pipe on the internal part is enclosed, is fixed on an end part support plate, and is arranged in a wall plate; each dust removing pipe is provided with a plurality of conical jet orifices which are aligned with lower flat bag pattern holes which are formed in the form of matrix respectively; a plurality of filter bags can be jetted through one-time pulse, so that the jet air amount is large, and a good dust removing effect is achieved; and a connecting pipe of the external part is connected with the other end of each dust removing pipe of the internal part, passes out of the wall plate, and passes through a gas storage tank to be connected with a medium-sized pulse valve. The dust removing device is suitable for pulse jet dust removing equipment, has a simple structure, low pressure, small damage to the filter bags and good dust removing effect due to the adoption of a large air amount, and is easy and convenient to run and operate.
Description
Technical field
The invention belongs to the environmental protection equipment technical field, relate to a kind of pulse bag-type dust-removing equipment, relate in particular to a kind of pulse ash remover of fixed pulse bag type dust collector and use the cleaner of this device.
Background technology
Disclose a kind of blowing device of deduster in the market, formed by compact electromagnetic pulse valve (3 ~ 4 cun), branch gas tank, wallboard coupling, winding-up pipe, Venturi tube etc.Electromagnetic impulse valve is by pulse jet controller output signal controlling, by compressed air pipe network or air compressor air feed independently.The spray of the pulse spraying equipment of this structure is narrow-minded, can not reach desirable ash-removal effect, particularly to long filter bag easy-to-clean ash not, has therefore increased the weight of the operation burden of pulse bag type dust collector, has increased energy consumption; The purge mode of medium-pressure or high pressure is prone to cause filter bag damage and winding-up pipe serious wear; The pulse valve of this form blowing device is positioned at the side of gas bag, and repair and maintenance is inconvenience very; And because the filter bag limited amount that the compact electromagnetic pulse valve can be jetted causes whole deduster to use pulse valve quantity more, generally only arrive hundreds of tens, operational management is loaded down with trivial details, and the deduster equipment volume is huge, and steel consumption is many, invests bigger.
Another kind is the swiveling jetting device of band top gas storage pot type; Compressed air is stored in the special gas bag, and each rotary blowing unit is provided with independently a gas bag and a cover motor device, is installed on the deduster top; Compressed air and flue gas have the temperature difference, can cause dewfall and mouth of pipe corrosion phenomenon; If unit capacity is big, need supporting gas bag just to need to increase, the wind load Intensity Design also need increase, and the severity that gas bag rocks on the deduster top forms a kind of the phenomenon that big foot is light, and is all influential to transmission mechanism etc.
Summary of the invention
The objective of the invention is to the problems referred to above, and provide a kind of low pressure atm number fixed flat bag deashing device.
Apparatus of the present invention improve ash-removal effect, reduce damage to filter bag, cut down the consumption of energy, increase and strengthen electromagnetic impulse valve, reduce equipment volume, reduce pulse valve repair and maintenance workload, practice thrift investment.
Main technical schemes of the present invention: the fixed flat bag deashing device of low pressure atm number; Be the supporting pulse jet equipment of a kind of sack cleaner; Establish portion and peripheral hardware portion in mainly comprising; Technical characterstic be in the portion of establishing comprise the deashing pipe of end sealing; Some spouts are arranged on the deashing pipe, and there is flat bag card hole the spout below; Peripheral hardware portion comprises the tube connector that is connected with the deashing pipe other end, and tube connector passes air accumulator and is connected with medium-sized pulse valve.
Usually, device of the present invention mainly comprises deashing pipe, conical nozzle, air accumulator, medium-sized pulse valve, air inlet, flat bag card hole etc.In establish portion's deashing pipe end sealing, be fixed on the end portion, supports plate, be located in the wallboard; On the every deashing pipe some conical nozzles are arranged, aim at the flat bag card hole that the below is arranged respectively, the pulsatile once many filter bags of can jetting; It is large-minded to jet, and realizes good ash-removal effect; The tube connector of peripheral hardware portion links to each other with an interior end of establishing portion's deashing pipe, passes outside the wallboard, and passes air accumulator and be connected with medium-sized pulse valve.
Medium-sized pulse valve adopts the medium-sized pulse valve of diaphragm thickening, vertically is contained in the air accumulator top, has removed the inspection platform of pulse valve from.
Apparatus of the present invention can be according to on-the-spot needs, be provided with plurality of parallel in establish portion and peripheral hardware portion, the some medium-sized pulse valve of peripheral hardware portion uses a Rainproof case, simple in structure, maintenance management is easy.
After adopting this structure and purge mode, deashing pressure is low, can prevent brokenly effectively that the bag phenomenon takes place, and prolongs life of bag filter; Deashing is large-minded, can easily remove the appearance ash of filter bag; The arranged mode in flat bag card hole, floor space is little, and filter bag arranges that quantity is many, thereby the pulse valve usage quantity is reduced, and cost of investment is low, and the maintenance rate is low.
