Abstract

The utility model discloses a collector for reducing VOC discharges to collect and handles tail gas, including four sections jar bodies and a cone bottom head of vertical direction, the jar is personally experienced sth. Part of the body and all is the cylindricality, the internal portion of top layer jar is equipped with the activated carbon adsorbed layer, and the internal portion of second floor jar is equipped with the layer that sprays of netted range, and the inside of the third layer jar body is equipped with metal packing layer, the inside coil heat exchanger that is equipped with of the bottom jar body and conical head, four sections column jars are personally experienced sth. Part of the body by flange joint, and inside communicates with each other, and the bottom jar body and conical head link to each other through the welding, and inside communicates with each other, the top layer jar body is last closed form. This collector has improved the structure, and low temperature carrier through great area sprays exhaust tail gas in the contact production process, reaches the effect that the cooling is slowed down, rethread active carbon adsorption, VOCS content in the tail gas that significantly reduces, final discharge to reach standard.

Description

A kind of catcher processing tail gas for reducing VOC emission collection

Technical field

This utility model relates to epoxy resin production technology, particularly to a kind of catcher processing tail gas for reducing VOC emission collection.

Background technology

Epoxy resin is the organic high molecular compound referring to and containing two or more epoxide groups in molecule, and the relative molecular mass of general conventional product is not high. the molecular structure of epoxy resin is to be its feature containing active epoxide group in strand, and epoxide group may be located at the end of strand, centre or structure circlewise. due in molecular structure containing active epoxide group, make they can with polytype firming agent generation cross-linking reaction and formed and insoluble, not molten there is the cancellated high polymer of three-dimensional. epoxy resin after solidification has good physical and chemical performance, the surface of metal and nonmetallic materials is had the adhesive strength of excellence by it, dielectric properties are good, shrinkage factor is little, product size good stability, and hardness is high, pliability is better, to alkali and major part solvent-stable, thus it is widely used in national defence, each department of national economy, pours into a mould, impregnate, the purposes such as lamination material, bonding agent, coating. domestic epoxy resin process units starts one after another, but always have in the process producing epoxy resin and discharge containing organic tail gas in a large number, and at present China is in and administers haze energetically, it is strictly on guard against air-polluting crucial moment, so how reduce VOCS contained in the tail gas difficult problem just having become the industry to capture, current more utilization is technology and the activated carbon adsorption of multi-stage condensing, the former is namely by making the coagulated Organic substance in tail gas liquefy tail gas cooling, reach to reduce organic gas discharge, but this tail gas after multi-stage condensing so contains the VOCS of higher concentration. the latter is that life cycle is short, cost is high, often becomes ornaments. for such problem inventor through investigation widely and test, obtain new collection technique, be substantially reduced VOCS discharge.

Utility model content

It is two kinds of methods that the processing method of current chemical industry tail gas is used more, and one is the technology of application multi-stage condensing; Two is direct activated carbon adsorption. But right VOCS containing higher concentration in the tail gas that the former discharges, the latter's activated carbon life cycle is very short, process relatively costly. For this, this utility model provides a kind of catcher processing tail gas for reducing VOC emission collection, collects Organic substance in tail gas, reduces the discharge of organic solvent, accomplishes that environmental protection produces, and reduces producing the cost of raw material simultaneously, improves product price competitiveness.

This utility model be the technical scheme is that by its technical problem of solution

A kind of catcher processing tail gas for reducing VOC emission collection, including four sections of tank bodies, these four sections of tank bodies are all cylindricality, described four sections of tank flanges are connected, end section tank body and conical bottom end socket are weldingly connected, top section tank body is upper closing staving, which is provided with four air vents connected with tank interior, bottom pyramidal end socket is provided with the organic solvent outlet connected with tank interior, described four sections of tank interior are respectively equipped with activated carbon, spraying layer, metal packing and coil heat exchanger from top to bottom, and section tank wall portion is provided with the inlet exhaust gas in four orientation at the described end.

The utility model has the advantage of,

This catcher improves structure, can be combined processing to containing organic tail gas by multiple method, is first discharged to by tail gas in a bigger space and reduce exhaust velocity, reduce the Organic substance liquid that tail gas stream is carried; Make it lower the temperature with low temperature carrier spray and slow down in the process that tail gas rises again, by descending for the liquefaction of high boiling Organic substance; Finally by activated carbon, micro residue Adsorption of Organic is lived, be finally reached the effect of tail gas clean-up.

Accompanying drawing explanation

Fig. 1 is the structural representation of the catcher that the utility model proposes.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with diagram and specific embodiment, this utility model is expanded on further.

As it is shown in figure 1, the catcher that the utility model proposes includes four tank bodies B, C, D, E, tank body is cylindricality, and the bottom of tank body E is provided with conical bottom end socket F.

Tank body B presents closed, and top is provided with four air vents " 1 " connected with inside, and inside is provided with activated carbon adsorption layer P.

Being provided with spraying layer x inside tank body C, tank skin is provided with two sprays low temperature carrier import " 2 ".

Packing layer y it is provided with inside tank body D.

Setting coil heat exchanger z inside tank body E, tank skin is provided with the inlet exhaust gas " 3 " of four different directions and the import " 4 " of a freezing carrier being connected with coil heat exchanger.

Conical bottom end socket F is provided with the organic solvent condensate outlet " 6 " that connect internal with tank body F; Wall portion is provided with the outlet " 5 " of and the coil heat exchanger z freezing carrier being connected.

Tank body B, C, D, E use flange bolt, and " 7 " connect.

Catcher adopts four different azimuth uniformly to input the tail gas containing organic solvent, and owing to tank body E diameter is far longer than the pipe diameter of input tail gas, tail gas upflow velocity significantly declines, and the Organic substance liquid being now entrained in tail gas drips descending one after another; Lose a part of organic tail gas and slowly drench packing layer y rising in the low temperature carrier traverse tank body D that in tank body C, spraying layer x sprays, tail gas now obtain further slow down and lower the temperature fully, most organic gas therein be condensed liquefaction descending; Micro residue Adsorption of Organic is lived by last slowly up tail gas by activated carbon, and air is by " 1 " discharges. It is finally reached the effect of tail gas clean-up.

Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described. Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model. This utility model claims scope and is defined by appending claims and equivalent thereof.
