Abstract

The utility model relates to a device for purifying the smoke and dust of a boiler, which is composed of a purifying box, an air inlet pipe, an air outlet pipe, a liquid inlet pipe, a dirt exhausting pipe and a draught fan. The boiler smoke gas is exhausted after passing through the purifying liquor. The utility model has the advantages of simple device and high efficiency. The device for purifying the smoke and dust of a boiler can be widely installed on various boilers with different size and forms.

Description

Device for purifying smoke and fume of boiler

The utility model relates to a kind of boiler soot purifying device.

Along with development of times, environmental pollution has become the much-talked-about topic of people institute concern, the flue dust of boiler is the most stalwart one of head that obtains of environmental pollution, at present, the method for processing boiler smoke has spray process, filtration method, electrostatic method etc., but these methods all have only the efficiency of dust collection of 70-90%, poison gas in the flue gas almost there is not catharsis, and the equipment complexity, noise is big, installation inconvenience.

The purpose of this utility model provides a kind of efficiency of dust collection height, the simple boiler soot purifying device of equipment

The purpose of this utility model is to realize like this.A kind of boiler soot purifying device, it comprises the sealing purifying box, the purifying box support, air inlet pipe, feed tube, escape pipe, blow-off pipe, air-introduced machine, free vent with unidirectional valve gap, in the described purifying box scavenging solution is housed, leave the gas compartment on the liquid level, air inlet pipe, feed tube, escape pipe seals respectively and is connected on place, associated hole on the purifying box, air inlet pipe one end inserts in the liquid, air-introduced machine is installed on the escape pipe, purifying box is equipped with the liquid level gauge blow-off pipe and is installed in the purifying box bottom, blow-off pipe, be separately installed with blowoff valve on the feed tube, the feed liquor valve, free vent communicates with flue gas in the air inlet pipe.

Described scavenging solution is akaline liquid, water etc.

Described air inlet pipe is inserted 1/2nd places in the scavenging solution.And staying outside one end is horn mouth, and described free vent with unidirectional valve gap is opened on air inlet mouth of pipe outer pot stove flue damper, and these unidirectional valve gap electricity consumption magnet control open and close, and this electromagnet is connected with the fan power switch interlock.

For easy for installation, described air inlet pipe, escape pipe are formed by several sections, the section with section between connect with flange.

In order to prevent that the bulky grain dust from being brought into purifying box by flue gas, there is screen pack in air inlet pipe import department.

The utility model is owing to adopted the mode of flue gas by scavenging solution purification flue dust, and efficiency of dust collection can reach more than 98%, and the poison gas in the flue gas is also had catharsis preferably, and equipment is simple, and is easy for installation.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is an embodiment schematic diagram of the present utility model

As shown in Figure 1, sealing purifying box 1 is installed on the purifying box support 2, and scavenging solution 9 wherein is housed, and leaves the gas compartment 10 on the liquid level, and horn mouth air inlet pipe 3 is inserted in the scavenging solution 9, and the position not too not deeply, too not shallow yet, is preferably in liquid level 1/2nd places.Horn mouth air inlet pipe 3, feed tube 4, escape pipe 5 seal respectively and are connected on place, associated hole on the purifying box.Air-introduced machine 7 is housed on the escape pipe 5, can selects the air-introduced machine 7 of different capacity according to the size of boiler.On purifying box 1 wall liquid level gauge 1 is housed, blow-off pipe 6 is arranged at purifying box 1 bottom.Be equipped with respectively on blow-off pipe 6, the feed tube 4 that blowdown cuts down 12, feed liquor cuts down 13, purifying box 1 is placed on the support 2.When preventing boiler pressuring fire, fire is extinguished, be provided with the plate washer 14 of band free vent 8 in 3 mouthfuls of outer boiler chimneys of horn mouth air inlet pipe, unidirectional valve gap 15 is arranged on this free vent 8, this unidirectional valve gap 15 is by the magnet control open and close, and this electromagnet is connected with switch 17 interlockings of air-introduced machine 7, after air-introduced machine 7 stops, this valve gap 15 is opened automatically, keeps stove to ventilate to a certain extent.The also available control mode with other of unidirectional valve gap 15 is as with manual pull-up of backguy etc.In order to prevent that the bulky grain dust from entering in the purifying box 1, the air inlet mouth of pipe is outer, screen pack 16 is installed in the boiler chimney air flue.

During use, the sealing of air inlet pipe 3 horn mouths is connected between boiler chimney screen pack 16 and the baffle plate 14, starting air-introduced machine 7, flue gas will pass through the scavenging solution dedusting, discharge from escape pipe the back of taking drugs.By the liquid level that liquid level gauge can be observed scavenging solution at any time, behind the waste discharge, can pass through feed tube after-purification liquid.This kind boiler soot purifying device can be suitable for all size boiler erection, is a kind of comparatively ideal purifier.
