Abstract
The utility model relates to a kind of waste gas recovering device for nitro-cotton digester, comprise digester, tank, water pipe, force (forcing) pump, water in tank squeezes into digester by force (forcing) pump, digester top is provided with hot gas relief outlet, this hot gas relief outlet passes in interchanger by hot gas transfer tube, be provided with rising pipe and air outlet in interchanger, rising pipe passes in tank, and top, air outlet is provided with waste gas collection device or is communicated with packing tower.The waste gas introducing interchanger that neutralization reaction in digester produces by regulating circuit design by the utility model, water temperature in interchanger is raised, water after heating up is squeezed in tank again, improve the temperature of water trough inner water thus, decrease water trough inner water reheat to boiling time, improve heat transfer efficiency, strengthen the management of exhaust gas emission simultaneously.
Description
Technical field
The utility model belongs to energy-saving and emission-reduction apparatus field, relates to nitro-cotton, especially a kind of waste gas recovering device for nitro-cotton digester.
Background technology
Along with the development of science and technology, the range of application of nitro-cotton is no longer confined on war products, but is embodied in the every aspect of daily life, such as Automobile paint, solid alcohol and electronic product binding agent etc.Nitro-cotton needs carry out in separation and boiling water and slough wherein excessive spent acid in nitrated rear needs respectively, wherein and operation normally the nitro-cotton after depickling is carried out having boiled in digester in and, wash and neutralization reaction owing to relating to boiling simultaneously, not only need constantly to supply water, note also the discharge of the hot waste gas of generation, the hot waste gas of discharging for these at present does not only have effective retrieving arrangement, and discharge also can produce potential safety hazard accidentally.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of structure is simple, reasonable in design, the waste gas recovering device for nitro-cotton digester of highly effective and safe.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of waste gas recovering device for nitro-cotton digester, comprise digester, tank, water pipe, force (forcing) pump, water in tank squeezes into digester by force (forcing) pump, digester top is provided with hot gas relief outlet, this hot gas relief outlet passes in interchanger by hot gas transfer tube, be provided with rising pipe and air outlet in interchanger, rising pipe passes in tank.
And, the water pipe line between described force (forcing) pump and digester is provided with well heater.
Advantage of the present utility model and positively effect are:
The water vapour introducing interchanger that neutralization reaction in digester produces by regulating circuit design by the utility model, water temperature in interchanger is raised, water after heating up is squeezed in tank again, improve the temperature of water trough inner water thus, decrease water trough inner water reheat to boiling time, improve heat transfer efficiency, achieve the recycle of the energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of waste gas recovering device for nitro-cotton digester, comprise digester 4, tank 8, water pipe 1, force (forcing) pump 9 and well heater 2, tank is communicated with the water-in 3 on digester by water pipe, tank, by the water pipe line between water pipe and digester is provided with force (forcing) pump, the water pipe line between force (forcing) pump and digester is provided with well heater.
Innovative point of the present utility model is:
Digester top is provided with hot gas relief outlet, and this hot gas relief outlet enters in interchanger 6 by hot gas transfer tube logical 5, and be provided with rising pipe 7 and air outlet in interchanger, rising pipe passes in tank.
Principle of work of the present utility model is:
To make in interchanger water temperature raise, the water after heating up is squeezed in tank again, improves the temperature of water trough inner water thus, decrease water trough inner water and reheat time to boiling.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
