Abstract
The invention relates to a self-cleaning high-flow gas filtering apparatus. The invention comprises a gas filter body and is characterized in that: one end of the gas filter body is provided with a gas inlet, and the other end of the gas filter body is provided with a gas outlet; wind guiding devices are provided at the gas inlet and the gas outlet; the filtering apparatus is provided in the gas filter body, the top of the filtering apparatus is provided with a filter screen out-taking opening, the bottom of the filtering apparatus is provided with a sewage draining exit, one side of the filtering apparatus is provided with an automatic spraying and flushing means which is connected with a differential pressure display instrument arranged out of the gas filter body. The advantages of the invention are as follows: the service life of a filter screen is prolonged; filtering efficiency is improved, the service life of a filter core is prolonged, and the backwashing cycle of the filter core is increased; the whole process is automatically carried out through program control, needing no manpower and being time-saving and labor-saving.
Description
Technical field
The present invention relates to the coal gas filter, relate in particular to a kind of self-cleaning gas of high flow rate filter.
Background technology
Gas filter drain cock is the visual plant of gas transmission and distribution system, in the gas distribution process, for the operate as normal of valve members such as assurance equipment and instrument such as pressure regulator and instrument such as flowmeter, Pressure gauge with protect it not to be damaged; Must remove the solid impurity in the coal gas, before it, suitable filter must be installed, existing gas filter drain cock adopts the stainless steel cloth filter core; Exist the coal gas treating capacity little, filter screen is prone to stop up, and cleans difficulty; Shortcomings such as the mounting or dismounting of filter cylinder are time-consuming, effort, and equipment resistance is big.
Summary of the invention
The purpose of this invention is to provide a kind of self-cleaning gas of high flow rate filter.
The technical scheme that the present invention adopts is:
Self-cleaning gas of high flow rate filter; Comprise the gas filter drain cock body, said gas filter drain cock body one end is provided with gas entry, and the said gas filter drain cock body other end is provided with gas exit; Said gas entry place and gas exit place are equipped with air ducting; Be provided with filter in the said gas filter drain cock body, said filter top is provided with the filter screen conveying end, and said filter bottom is provided with sewage draining exit; Said filter one side is provided with the automatic spray flusher, and this external pressure reduction Displaying Meter of said automatic spray flusher and gas filter drain cock links to each other.
Said air ducting is the water conservancy diversion grid.
Said filter comprises a plurality of filter cores, is provided with screen pack in the said filter core, and said filter core head and the tail link to each other successively and form the W type.
Said automatic spray flusher comprises Butterworth Hatch and blowback steam inlet.
Advantage of the present invention is: air inlet, gas outlet all are provided with air ducting, and (going out) mouthful coal gas is evenly spread, and air-flow is evenly distributed, and the protection screen pack is not impacted by high velocity air, has prolonged the service life of filter screen; Element kit adopts and filters the special-purpose shuffling net of coal gas, has higher permeability, and surface area is big, and water environment capacity is strong, the difficult obstruction; The installation of filter core is W shape, and this installation form forms bigger filter area, reduces filtering velocity, improves filter efficiency, prolongs filter core service life, has increased the backwash cycle of filter core; The automatic spray flusher is set, after filter uses a period of time, forms pressure reduction in the filter core both sides, after pressure reduction reaches the capping value; Automatically open backwash procedure, the backwash magnetic valve is opened, and utilizes steam that filter core is washed, and the impurity such as solid particle, tar that accumulate in screen surface break away from screen surface under the flushing of steam; Make filter screen obtain regeneration, prescribe a time limit when pressure reduction reaches under the setting value, backwash finishes; Whole process is carried out through programme-control automatically, need not manual work, saves time and laborsaving.
