Abstract

The utility model discloses a gas cycling, purifying and filtering device which comprises a box body, a gas input flange and a gas output flange, and is characterized in that filter net slots are processed on the inner side walls of the box body; stainless steel filter nets are inserted in the filter net slots; a collecting cover with a backflow valve is mounted at the bottom end of the box body; and a high-pressure washing valve is arranged on a box cover. The utility model utilizes the inertia impaction and diffusion impaction generated between the gas impurities and rows of stainless steel filter nets in the processes of inertia motion and diffusion motion of the gas impurities flowing along with gas at high speed, gas passes through the nets and the impurities fall down freely, and therefore the purposes of purifying and filtering are achieved. The device can wash and clean the stainless steel filter nets with high pressure water without opening the box cover, so that the purpose of ensuring continuous working of the filter is ensured. The device has the advantages of high filtering accuracy, small volume, strong impurity treatment capability, convenient cleaning, maintenance and overhauling, recyclable use of filter nets and low cost.

Description

The pure filter of gas circulation

Technical field

The utility model relates to gas-filtering device, especially relates to the pure filter of a kind of gas circulation.

Background technology

All gas manufacture and course of conveying in all can accompanying impurities, these impurity are understood corrosion pipeline, blocking pipe in the gas course of conveying, so they must be filtered out.Filter is exactly to come from this type of situation and a specific technique producing.The filtration particle diameter that filtering technique is generally followed assurance to be needed requires, reduces as far as possible the principle of the pressure loss, and is simple and safe to the processing requirements of impurity, do not influence gas and normally carry, and reduces maintenance times as far as possible, reduces consumable accessory.Filtering technique has two kinds of cyclone type filter and filer element type filters, and wherein the filtering accuracy of cyclone type filter is lower, volume is bigger, is unfavorable for the less contaminant filter of particle diameter; Although and filer element type filter precision can be done very highly, less to the disposal ability of impurity, safeguard and maintenance inconvenience and filter core rapid wear, to change frequency higher that cost is also higher.

Summary of the invention

The purpose of this utility model be to provide a kind of filtering accuracy height, volume less, strong to the disposal ability of impurity, clean, safeguard and maintenance all easily, screen pack can be recycled, cost the is low pure filter of gas circulation.

The purpose of this utility model is achieved in that the utility model comprises casing, gas input flange and the gas output flange of the equal opening of upper and lower side, feature is to be even spaced screen pack slot more than being processed with two rows on two sidewalls parallel, relative with gas flow in casing, be placed with in every row's screen pack slot interpolation be positioned over more than one in the box cavity, the stainless steel screen pack vertical with gas flow; On the sidewall end face around the casing, evenly be processed with the casing screw, be processed with the case lid hole corresponding in the edge of case lid, case lid is fixed on the casing by screw with the casing screw.

The collecting hood of taking back the stream valve is installed in the bottom of casing.

On case lid, be provided with the high pressure washing valve, the impurity drain valve be installed in the bottom of collecting hood.

The mesh order number of stainless steel screen pack is the 80-1800 order.

The utility model is to be placed with several rows of stainless steel screen pack in the casing interpolation, according to the pure filtering technique principle of gas circulation, it is to utilize gaseous impurity to do the inertial collision that produces with several rows of stainless steel screen pack in inertia motion and the diffusion motion process and spread along with the gas flow at high speed time to collide, gas is worn net and mistake, impurity is free-falling then, thereby reaches the purpose of purification filtering.The utility model so long as they are doing random Brownian movement, can both reach the filter effect of the best in when work granular size of impurity and hydrone no matter.On case lid, be provided with the high pressure washing valve, in the bottom of collecting hood the impurity drain valve is installed, after work a period of time, the staff need not open case lid and with regard to available water under high pressure the stainless steel screen pack be washed away, and cleans the impurity on the stainless steel screen pack, thereby reach the purpose that guarantees the filter continuous operation, certainly also can open case lid, take out the several rows of stainless steel screen pack that is stained with dust and thoroughly clean, it can be pacified back original position again after having cleaned, the case lid that closes works on.Therefore, the utlity model has filtering accuracy height, volume less, strong to the disposal ability of impurity, clean, safeguard and maintenance all easily, screen pack can be recycled, cost is low advantage, be a kind of new gas pure filter that circulates.

The specific embodiment

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.

The utility model comprises casing 6, gas input flange 2 and the gas output flange 5 of the equal opening of upper and lower side, be even spaced screen pack slot 12 more than in casing 1, being processed with two rows on two sidewalls parallel, relative with gas flow, be placed with in every row's screen pack slot 12 interpolations be positioned over more than one in the box cavity 10, the stainless steel screen pack 3 vertical with gas flow; On the sidewall end face around the casing 6, evenly be processed with casing screw 11, be processed with the case lid hole 13 corresponding in the edge of case lid 4, case lid 4 is fixed on the casing 6 by screw with casing screw 11.

The collecting hood 7 of taking back stream valve 1 is installed in the bottom of casing 6.

On case lid 4, be provided with high pressure washing valve 8, impurity drain valve 9 be installed in the bottom of collecting hood 7.
