Description

Industrial gas dust removal device
Technical Field
The invention relates to the technical field of environmental protection, in particular to an industrial gas dust removal device.
Background
In the production industries of metallurgy, machinery, chemical industry, building materials and the like and in the energy conversion process of boilers, kilns and the like, a great amount of dust-containing gas is often generated and needs to be subjected to environment-friendly dust removal treatment, and the existing dust removal mode mainly adopts cloth bag dust removal. The bag-type dust collector is internally provided with a filter element, and after the gas with dust passes through the filter element, the filter element filters the gas, so that the dust is adhered to the filter element, and the purpose of filtering is achieved. However, as the filter element absorbs more and more dust, and the adsorption capacity of the filter element is reduced, so that the dust removal effect is reduced. In order to improve the dust removal effect, the filter element needs to be cleaned or replaced manually, and the operation is troublesome.
Disclosure of Invention
The invention aims to provide an industrial gas dust removal device to realize automatic cleaning of a filter element.
In order to achieve the purpose, the basic technical scheme of the invention is as follows: an industrial gas dust removal device comprises an ash bucket and a filter element, wherein the filter element is positioned at the top of the ash bucket, the side part of the ash bucket is connected with an air inlet pipe, the filter element has elasticity, the filter element is provided with an air vent, the bottom of the ash bucket is communicated with a water tank, a filter plate is arranged between the ash bucket and the water tank, one side of the ash bucket is provided with a water absorber, the water absorber comprises a cavity and a piston, the piston is connected on the inner wall of the cavity in a sliding manner, a water pipe is communicated between the bottom of the cavity and the water tank, the joint of the water pipe and the cavity is a water inlet, the water inlet is covered with a first rubber plate which is rotatably connected with the bottom of the cavity, the piston is provided with an opening, the opening is covered with a second rubber plate which is rotatably connected with the piston, a guide rail is arranged above the cavity, a slide block, a second connecting rod is rotatably connected between the guide rail and the filter element, a third connecting rod is rotatably connected between the middle part of the second connecting rod and the sliding block, a guide pipe is communicated with the cavity and extends into the ash bucket, and a spray head is arranged at one end of the guide pipe extending into the ash bucket.
The working principle of the scheme is as follows: the industrial gas enters into the ash bucket through the air inlet pipe, wherein the bottom of the ash bucket is fallen to the bigger dust of granule under the effect of gravity, collects, and the smaller dust of granule is followed gaseous rebound, is adsorbed by the filter core, and the dust adhesion is on the filter core. The purified gas is discharged to the external environment through the vent hole. The turntable, the first connecting rod and the sliding block form a slider-crank mechanism, when the turntable rotates, the sliding block is driven to move on the guide rail in a reciprocating mode, then the sliding block drives the second connecting rod to rotate around the joint of the second connecting rod and the guide rail through the third connecting rod, the second connecting rod drives the filter element to stretch and contract continuously, the filter element vibrates, and therefore dust on the filter element vibrates and falls to the bottom of the dust hopper. Meanwhile, when the sliding block moves in a reciprocating mode, the iron rod drives the piston to move up and down in the cavity in a reciprocating mode, when the piston moves upwards, the piston sucks air upwards, the first rubber plate is opened, the air enters the cavity from the water pipe, when the piston moves downwards, the sucked air overflows from the cavity, the pressure inside the water pipe is reduced, and water in the water tank is pressed into the cavity under the action of the external atmospheric pressure. Then flows to the spray head through the conduit and sprays water into the ash bucket.
When the technical scheme is adopted, the filter element has elasticity, the filter element vibrates back under the rotation of the second connecting rod, and the adsorbed dust on the filter element vibrates to fall, so that the automatic cleaning of the filter element is realized, the dust on the filter element can not be accumulated too much, the adsorption capacity of the filter element is ensured, and the automatic cleaning of the filter element is free from manual cleaning and filter element replacement, the working strength of workers is reduced, and the operation is convenient. The water sprayed from the spray head can cool the gas, so that the temperature of the high-temperature industrial gas is reduced, the temperature of the discharged gas is lower, and the environment protection is facilitated. On the other hand, the falling dust can be condensed by the water, so that the gravity of the dust is increased, the falling speed of the dust is accelerated, and the efficiency of cleaning the dust in the gas is improved.
Furthermore, a spring wire penetrates through the side wall of the filter element, and the side wall of the filter element is made of flexible materials. The spring wire enables the filter element to have elasticity, and the filter element made of flexible materials can enable the filter element to be freely stretched, so that the filter element can stretch out and draw back.
Further, the opening is located the middle part of piston, and fixedly connected with covers the open-ended and carries and draw the cover, carries to draw and covers including a plurality of through-holes, and iron set fixed connection is at the top of carrying and drawing the cover, can make the structure on the piston more symmetrical like this, when guaranteeing iron set pulling piston, the piston atress is even, and steady slip in the cavity.
Furthermore, the first connecting rod, the rotating disc, the sliding block, the second connecting rod and the guide rail, and the third connecting rod, the sliding block and the second connecting rod are rotatably connected through pin shafts. The pin shaft is a common rotating connecting piece, is convenient to purchase and configure and has lower cost.
Furthermore, the lower part of the ash bucket is in a table shape, and the small-diameter end of the ash bucket is positioned at the bottom of the ash bucket. Therefore, the bottom of the ash bucket is inclined downwards, and dust falling on the side wall of the ash bucket can slide downwards along the inclined plane at the bottom of the ash bucket, so that the dust can fall conveniently.
Further, the inside spout that link up that is equipped with of slider, guide rail sliding connection are in the spout, and like this, the guide rail is lived by the slider parcel, and the slider can not deviate the guide rail when sliding on the guide rail, prevents slider and guide rail separation.
