Description

Longitudinal ozonolysis equipment

Technical field

The utility model belongs to field of environment protection equipment, specifically a kind of longitudinal ozonolysis equipment.

Background technique

With the quickening of process of industrialization, atmosphere pollution is also increasingly serious, the improvement of VOC is referred to increasingly urgent Process.The technology of common removal VOC has low-temperature plasma, absorption, photocatalysis, burning etc..Wherein low-temperature plasma utilizes it Electric discharge generates high energy electron and hydroxyl radical free radical grade height active particle, can quickly by the thorough mineralising of organic matter be CO2 and H2O, have the characteristics that removal thoroughly, it is low energy consumption, easy to operate, obtained more and more applications in the removal field VOC.But Low-temperature plasma device in the process of running, the high energy electron of generation of discharging may decomposed oxygen form ozone, it is practical Measured value is far longer than 0.12ppm specified in " standard for atmosphere environment quality " in 20-30ppm, needs to be subject to removal processing. Chinese patent literature CN205760621U discloses " a kind of cabin fresh air ozone conversion equipment ", ozone on December 7th, 2016 Converter core is perpendicular or parallel to be arranged in body interior；Ozone converter core is made of multiple catalyst-assemblies；Catalyst Device includes fixed device, is equipped with catalyst structure layer in the two sides of fixed device；Catalyst structure layer is existed by uniform load The ozone removal catalyst composition of sorptive material external surface.Its inventor declares, contains ozone from aircraft engine bleed Fresh air air-flow, is entered inside ozone converter by fresh air inlet, is adsorbed on the surface of catalyst structure layer and by catalyst Catalytic decomposition, the air-flow up to standard after removing ozone enter cabin environmental control system after air stream outlet discharge and carry out air conditioning, reach The effect for improving that ozone removes under low consistency conditions has been arrived, has had the characteristics that ozone removal efficiency height and at low cost, realization ozone Decomposition removal purpose, may make fresh air ozone concentration to reach concentration range as defined in airworthiness standard.Due to the knot of the device Structure is relative complex, has strict requirements to the model and modes of emplacement of catalyst, needs to install inside ozone converter special Core, cause the space utilization rate of device low, ozone treatment is inefficient, thus keeps the processed in units cost of device very high, It is difficult to adapt to apply on a large scale.

Summary of the invention

Based on the above issues, the utility model provides a kind of longitudinal ozonolysis equipment, has structure simple, to catalysis Dosage form number adapts to wide advantage, can make full use of space, inexpensive processing ozone.

In order to realize invention mesh, the utility model adopts the following technical solution: a kind of longitudinal ozonolysis equipment, access In airflow pipeline, including circle tube tank body, tank body both ends are respectively connected with reducer pipe, are equipped with catalyst in tank body, tank body is vertical It sets；What is be adapted in tank body traverses equipped with supporting plate and pressure plate；Supporting plate is located at below pressure plate, relatively fixed with tank body；Pressure Tight plate can move freely in vertical direction；Array is equipped with the venthole in several full thickness directions on supporting plate and pressure plate；It urges Agent natural packing is between supporting plate and pressure plate.

In the technical program, it is desirable that by the vertical access of columnar tank body in airflow pipeline, to utilize gravity.Tool Be fixed with supporting plate in body structure, below tank body, on supporting plate natural packing catalyst, be pressure plate on catalyst.It holds Supporting plate is equipped with venthole, passes through from bottom to top for air-flow, and catalyst cannot be made to leak from the top down.Catalyst is optional more Kind model, can be according to gravity natural packing, it is only necessary to shakeout top, therefore interior in a limited space can place largely Catalyst can also select the catalyst of many low costs, to improve catalytic effect to reduce processing cost.It is same on pressure plate Sample is equipped with venthole, passes through from bottom to top for air-flow, and catalyst cannot be from the aerial escape upwards of ventilation.Supporting plate and compression The shape of plate is adapted to tank interior cross sectional shape.Pressure plate can be move freely up and down, therefore gravity can act on pressure On tight plate, catalyst is compressed from the top down, improves the usage amount of catalyst in the confined space.

Preferably, the quality of pressure plate is not less than the 1/2 of catalyst gross mass.The quality requirement of pressure plate is larger, because Catalyst buildup can effectively be laminated tight by this.Different catalyst amounts is different, and quality is different, can select different quality Pressure plate be adapted to use.

Preferably, the upper surface of supporting plate and the lower surface of pressure plate are all covered with wire mesh.Wire mesh can be with Catalyst is effectively blocked to escape or leak downwards upwards.Before matching reliable wire mesh always and blocking catalyst It puts, the requirement to the venthole on supporting plate and pressure plate can be greatly reduced, to reduce cost.To different-grain diameter Catalyst, also can choose the wire mesh of different mesh sizes.

Preferably, with flanged joint between tank end and reducer pipe.Diameter is consistent up and down for tank body, can be convenient catalysis The replacement of agent, the installation of supporting plate and pressure plate placement.Tank interior after treatment, it is only necessary to by flange again with change Diameter pipe is fixed.

Preferably, being equipped with gap between supporting plate and tank body lower end；Gap is equipped between pressure plate and tank body upper end.It holds Gap is equipped between supporting plate and tank body lower end, this gap forms tank body lower end admission space；Likewise, pressure plate and tank body Gap is equipped between upper end, this gap forms tank body upper end air outlet space.It is brought out on tank body lower end admission space and tank body Headroom advantageously reduces or avoids the short stream of gas, helps to improve treatment effect.

In conclusion wide to catalyst model adaptive surface is excellent the beneficial effects of the utility model are: having structure simple Gesture can make full use of space, inexpensive processing ozone.
