Abstract
The invention discloses in a kind of formalin and case, comprise formalin gas access, gas outlet and Electric air valve, described formalin gas access is connected with ammonia generator, and ammonia generator is connected with hexamethylenamine gathering-device, and hexamethylenamine gathering-device is connected to gas outlet; Controller is provided with in described formalin He in case; Ozonator, ozone gas outlet and Electric air valve is also included with case in described formalin; In formalin of the present invention and case, during in sterilized space, formaldehyde gas and ammonia carry out before can forcing and process, shift in and case in carry out neutralization reaction, to generate hexamethylenamine white crystal in and effectively collect in case, can so that cleaning hexamethylenamine; Can realize thoroughly removing formaldehyde gas object residual in sterilized space simultaneously.
Description
Technical field
The present invention relates to a kind of disinfector, be specifically related in a kind of formalin and case.
Background technology
Aqueous solution containing formaldehyde 37 %-40 % is called formalin, after formalin is heated into gas, has the sterilization effect of broad-spectrum high efficacy, is already needed the place extensive use of thorough sterilizing by hospital, pharmaceutical factory etc.Because formaldehyde taste is large and harmful, the formaldehyde still contained in the space after by sterilizing is therefore needed to neutralize.People pass in sterilized space with ammonia steam and neutralize before this, and its chemical equation is:
6 HCHO+4 NH
3→C

4wall can be remained in, machine surface.This is unallowed in medicine, food service industry, wants at substantial manpower to carry out craft for this reason and cleans, and be difficult to accomplish thorough removing.
Summary of the invention
The technical issues that need to address of the present invention are just the defect overcoming prior art, provide in a kind of formalin and case, it can to generate hexamethylenamine white crystal in and effectively collect in case.
In order to achieve the above object, the present invention adopts following technical scheme:
In a kind of formalin and case, comprise formalin gas access, gas outlet and Electric air valve, described formalin gas access is connected with ammonia generator, and ammonia generator is connected with hexamethylenamine gathering-device, and hexamethylenamine gathering-device is connected to gas outlet; Controller is provided with in described formalin He in case;
In order to realize thoroughly removing residual formaldehyde gas object, in described formalin, also include ozonator, ozone gas outlet and Electric air valve with case;
In order to make formaldehyde gas and ammonia in and abundant hybrid reaction in case, described hexamethylenamine gathering-device is rectangular cases, and described chest two ends arrange gas access and gas outlet;
For the ease of cleaning hexamethylenamine, described chest sidewall is provided with chute, described chute place is provided with the rustless steel filtering baffle can extracted out along chute, and described rustless steel filtering baffle is provided with handle;
In order to accelerated reaction, in described rustless steel filtering baffle, be provided with the resistance wire for heating.
Advantage of the present invention and beneficial effect are: in formalin of the present invention and case, during in sterilized space, formaldehyde gas and ammonia carry out before can forcing and process, shift in and case in carry out neutralization reaction, to generate hexamethylenamine white crystal in and effectively collect in case, can so that cleaning hexamethylenamine; Can realize thoroughly removing formaldehyde gas object residual in sterilized space simultaneously.

Detailed description of the invention
As shown in Fig. 1, in a kind of formalin and case, comprise formalin gas access 1, gas outlet 5 and Electric air valve 4, described formalin gas access is connected with ammonia generator 2, ammonia generator is connected with hexamethylenamine gathering-device 3, and hexamethylenamine gathering-device is connected to gas outlet; Controller 9 is provided with in described formalin He in case; Ozonator 6, ozone gas outlet 8 and Electric air valve 7 is also included with case in described formalin;
Hexamethylenamine gathering-device structure chart as shown in Figure 2, described hexamethylenamine gathering-device is rectangular cases, described chest two ends are provided with gas access 1 and gas outlet 6, sidewall is provided with chute 4, described chute place is provided with the rustless steel filtering baffle 2 can extracted out along chute, and described rustless steel filtering baffle is provided with handle 3; The resistance wire 5 for heating is provided with in described rustless steel filtering baffle.
As shown in Figure 3, in formalin gas and the supporting air conditioning system schematic diagram of case; Formalin steam enters by Electric air valve 2, air-conditioning unit 6, electric fan 7, Electric air valve 8, high efficiency particulate air filter 9 space 10 needing sterilizing from formalin fumigating sterilizer 1; Gas after sterilizing enters ammonia generator 15, hexamethylenamine gathering-device 16 by medium effeciency filter 11, Electric air valve 13 from formalin gas recovery conduit 14, and remaining a small amount of gas is discharged by Electric air valve 17 with case from formalin; Medium effeciency filter is also connected with return air duct 5 by Electric air valve 12, return air duct is provided with fresh air inlet port 3 and Electric air valve 4; Close Electric air valve 12, open Electric air valve 13, enter and collect formalin gas program.
After the formaldehyde of the overwhelming majority (more than 80%) is neutralized, in and case in ammonia generator quit work, continue and controller 20 works with ozonator 18 in case in starting, open Electric air valve 19 and ozone is provided in sterilized space, a small amount of formaldehyde and ozone are reacted in sterilized space:
2 HCHO+2 O
3→2 CO
2+2 H
2O+O
2
Realize thoroughly removing residual formaldehyde gas object.
Last it is noted that obviously, above-described embodiment is only for example of the present invention is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection scope of the present invention.
