Abstract

The utility model discloses a novel catalyzing bed layer arrangement. The novel catalyzing bed layer arrangement comprises an outer shell, wherein an air outlet is arranged on the front portion of the outer shell, and an air inlet is arranged on the rear portion of the outer shell. A catalyzing bed layer I and a catalyzing bed layer II are arranged inside the outer shell, wherein the catalyzing bed layer II is arranged below the catalyzing bed layer I. A double-layer structure is adopted, in the condition that the sizes of the bed layers are equal, the air-distributing uniformity can be effectively improved, and thereby the catalytic reaction effect and the purification efficiency of waste gas are effectively improved. Due to the fact that the double-layer structure is adopted, the whole bed section is divided into two small beds layers, wherein the two small beds are connected with each other. The mechanical strength of the whole bed is effectively improved and the whole bed is not easy to deform. The breakdown of catalyst leakage caused by the fact that the bed deforms by being heated and being under stress is avoided. And simultaneously the resulted problem that the purification efficiency of the waste gas declines is avoided.

Description

A kind of new catalytic bed arrangement

Technical field

The utility model relates to a kind of new catalytic bed arrangement.

Background technology

Catalytic bed cloth is set up and is placed with catalyst, is used for the reaction that catalysis filters the gas of catalytic bed layout, reaches the purpose of purifying exhaust air.Existing catalytic bed is arranged, is single layer structure, and the catalytic bed of the type structure arranges that catalytic efficiency is lower; The catalytic bed of single layer structure is arranged under the impact force action that is blown into gas, and is yielding and produce fault, and then causes catalyst to leak, and the catalytic efficiency that causes catalytic bed to be arranged descends, and weakened the catalysis that is blown into gas and the effect of purification.

The utility model content

The technical problems to be solved in the utility model provides the catalytic bed that a kind of catalytic efficiency is high, structural strength is good and arranges.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of new catalytic bed arrangement, comprise shell, and the shell front portion is provided with the gas outlet, the shell rear portion is provided with air inlet, and described enclosure is provided with the catalytic bed I and is located at the catalytic bed II of catalytic bed I below.

As a kind of improvement, described catalytic bed I comprises catalyst layer I and carriage I, and the catalytic bed II comprises catalyst layer II and carriage II.

As a kind of improvement, be equipped with dividing plate between the bottom of the top of described catalytic bed I, catalytic bed II and catalytic bed I and the catalytic bed II, described dividing plate, catalytic bed I and catalytic bed II are split up into two spaces with enclosure.

As a kind of improvement, be provided with the bracing frame I that supports the catalytic bed I between described catalytic bed I and the dividing plate, be provided with the bracing frame II that supports the catalytic bed II between catalytic bed II and the outer casing inner wall.

As a kind of improvement, the support frame as described above I is the channel-section steel machining with the bracing frame II and becomes.

As a kind of improvement, described carriage I is the angle steel machining with the carriage II and becomes.

The technical solution adopted in the utility model, its beneficial effect is: adopt double-decker, in the situation that identical bed area, minute wind uniformity that can the Effective Raise bed, thus Effective Raise the catalytic reaction effect, improve exhaust purification efficiency; Adopt double-decker also so that whole bed cross section is divided into two interconnective little beds, the mechanical strength of whole bed effectively improves, not yielding, avoid the catalyst that stress deformation causes because bed is heated to reveal the fault that causes, avoided simultaneously the problem of the decline of the exhaust purification efficiency that therefore causes.
