Deduster provided with underlying blowing system and capable of clearing away ashes offline without offline valve

Abstract

The invention discloses a deduster provided with an underlying blowing system and capable of clearing away ashes offline without an offline valve. The deduster comprises a deduster shell composed of an ash bucket, a bag chamber, and gas purifying chambers, a gas outlet cabinet, and a blowing system; the ash bucket is provided with a gas inlet and an electric cinder valve, the bag chamber and the gas purifying chamber are separated by a card, a gas outlet is arranged in the gas outlet cabinet, a plurality of blowing and ejecting devices are arranged in the gas outlet cabinet, each blowing and ejecting device is corresponding to a gas purifying chamber, and the blowing system is arranged in the bottom of the gas outlet cabinet. The gas blowing system comprises a gas bag, a plurality of blowing pipes arranged in the gas outlet cabinet are connected to the gas bag, a connecting pipe, a movable connector, and an electromagnetic valve are arranged between each blowing pipe and the gas bag in sequence; and each blowing pipe is corresponding to one blowing and ejecting device. The deduster has the advantages that the blowing system is convenient for recondition and maintenance, the ash clearing force is large, at the same time the filter bag is prevented from being broken in advance, the filter bag and the bag cage are easy to install and change, the offline valve is cancelled, thus the equipment cost is reduced, the equipment operation becomes more stable, and the equipment manufacture is turned into modularization.

Description

technical field [0001] The invention discloses a dust remover, in particular to a dust remover with a bottom blowing system and no offline valve to realize offline dust removal. Background technique [0002] The bag filter is one of the main equipment for controlling industrial smoke pollution, and it is also one of the equipment for some production processes. With the continuous strengthening of the country's environmental pollution control and the adjustment of industrial policies, bag dust collectors have been widely used in many industries, and different industries have different forms of dust collectors, especially when dust collectors are used as equipment for production processes. The reliable and continuous operation of the equipment must be guaranteed. In order to respond to the national policy of energy saving and consumption reduction and to adapt to the environment in which the dust collector is used, various bag dust collectors are also constantly improving and...

Problems solved by technology

Looking at the characteristics of all the current pulse bag filter can be roughly divided into: 1. The injection system is placed on the top or the side of the top of the equipment. As we all know, the injection system is the core of the bag filter, so the operation reliability of the injection system The convenience of maintenance and maintenance is very important. When there is a fault such as a valve damage or air leakage in the injection system, the entire injection system must be shut down, which will eventually affect the operation of the dust collector. Once maintenance is required, the maintenance personnel must climb up It is extremely inconvenient to overhaul and maintain the top or the side of the top of the equipment, and it is not convenient to replace the filter bag and bag cage on the top; The industry generally uses long-bag low-pressure line-injection dust collectors for large air volumes, and air-box pulse dust collectors for small air volumes. If the design of the line-injection dust collectors is unreasonable for the blowing pipe, the production quality is difficult to guarantee, resulting in blown air during spraying. The dynamic and static pressure in the pipe is not equal, and the amount of air source injected into each filter bag is uneven, which often causes the filter bag to be damaged in advance, and the line-injected dust collector has high rigid consumption, high cost, and difficult production, while the air box type Although the cost of the pulse dust collector is low, the energy consumption is high and the operation effect is not good; 3. According to the dust removal method, the line cleaning and the online dust cleaning are separated. The normal offline pulse cleaning effect is definitely better than online cleaning, but there must be an offline valve on the offline dust collector. The offline valve itself is a running device, and the running device has a higher failure rate in a harsh environment. Failure of the off-line valve will affect the normal operation of the equipment. In addition, the off-line valve on the dust collector also increases the cost of the equipment.

There is still no thorough solution to the above problems, resulting in certain limitations in the use of dust collectors in some occasions.
