Description
Technical field
The present invention relates to a kind of system, keeps balance to remove internal pressure more particularly, in a kind of Furniture manufacturing workshop
Dirt system.
Background technology
In recent years, as economic develops rapidly, metallurgical steel-smelting electric furnace and the boiler with raw coal as fuel increase a lot, this
The atmosphere pollution of a little stove discharges causes very big harm to surrounding environment, so particulate matter is removed from dusty gas to reduce
It is more and more important to the technology of airborne release.Particulate matter is removed from dusty gas to reduce its technology to airborne release
Measure.Dust-laden industrial waste gas results from the mechanical processes such as crushing, screening, conveying, the explosion of solid matter, or results from combustion
The processes such as burning, high-temperature fusion and chemical reaction.The former contains big granularity, chemical composition and former solid matter identical dust, after
Person contains little granularity, chemical property and generates its material other flue dust.Improving production technology and combustion technology can be reduced
The generation of particulate matter.Deduster is widely used in dust and the flue dust that control has been produced.The investment opportunity of dedusting industry is derived from
The whole world is for the pay attention to day by day of environmental protection.Currently, the new round movement of environmental protection that the whole world is being risen will make energy-conservation environmental protection industry
Become one of 21 century global most potential industry.China is used as second-biggest-in-the-world economy and the developing china of maximum
Family, certainly will establish responsible environmentally friendly big country's image in the movement of environmental protection in the whole world.Due to the energy natural endowment condition institute of China
Limit, all the time coal is all the main primary energy of China, and nineteen ninety-five to coal in 2011 is in China's primary energy consumption
Average accounting is up to 70% or so.This energy resource structure based on coal determines carbon dioxide produced by coal burning, titanium dioxide
Sulphur, flue dust, dust etc. are the key factors for causing China's atmosphere pollution.Meanwhile, the height of the industry such as metallurgy, cement, waste incineration
The speed flue dust that brings of development, dust emission further increase the pressure of environmental protection.According to Chinese Ministry of Environmental Protection's data, China's cigarette in 2010
Dirt discharge capacity is 829.1 ten thousand tons, and wherein industrial fumes discharge capacity is 603.2 ten thousand tons.Flue dust, dust are mainly made up of particulate matter,
Can produce in a large number in the production of many industrial departments such as mining, metallurgy, machinery, building materials, light industry, electric power.For environment,
Enter air dust long-time float can reduce atmospheric visibility, coal-smoke pollution can be caused;For human body, inhalable
Dust can cause gradual pulmonary fibrosis, cause insufficiency of pulmonary function, trace heavy metal element, the radioactivity unit contained in dust
Element can also cause the fatal diseases such as senile dementia, leukaemia.In order to mitigate these harm, deduster is used as air dedusting
Main Means and equipment, it is widely used by each industrial department.In the presence of all kinds of dedusters, China's industrial fumes, powder
Dirt removal amount is lifted steadily.
The efficiency of traditional its dedusting of deduster is low, and for internal pressure cannot keep balance in dust removal process,
Cause gas easily to produce leakage, affect efficiency of dust collection, and easily cause equipment damage, affect service life.
The content of the invention
It is an object of the invention to overcome the efficiency of above-mentioned existing its dedusting of deduster low, and in dust removal process for
Internal pressure cannot keep balance, cause gas easily to produce leakage, affect efficiency of dust collection, and easily cause equipment damage,
The problem of service life is affected, is devised in a kind of Furniture manufacturing workshop and the dust pelletizing system of balance is kept to internal pressure, this is
The simple structure of system, efficiency of dust collection is high, and pressure compensation is carried out in time, can realize internal system pressure all the time in setting value,
Protection equipment safety, the efficiency for solving existing its dedusting of deduster is low, and for internal pressure cannot in dust removal process
Balance is kept, causes gas easily to produce leakage, affect efficiency of dust collection, and easily cause equipment damage, affect service life
Problem.
The purpose of the present invention is achieved through the following technical solutions：Balance is kept to internal pressure in a kind of Furniture manufacturing workshop
