Description
Technical field
The utility model is specifically related to a kind of positive pressure ventilating explosion-proof door socket applied in first, Class B workshop.
Background technique
Some regions would generally generate, overflow dangerous (inflammable and explosive) gas first, Class B workshop in process of production, these
Region is anti-explosion area.The facilities designs such as building structure, illumination, process equipment, HVAC in anti-explosion area all must be taken into consideration it is explosion-proof,
These safety devices investment is huge.
According to the requirement of " Code for fire protection design of buildings ", the air in first, Class B workshop should not be recycled.Therefore first,
Ventilation and air conditioning system is typically designed to direct current system (comprehensive air draft) in Class B workshop, and the investment of system and energy consumption are larger.
Utility model content
To solve the above problems, the utility model provides the positive draft type explosion-proof door socket in a kind of first, Class B workshop, lead to
The setting positive pressure ventilating explosion-proof door socket between general area and anti-explosion area is crossed, flammable explosive gas is isolated, is effectively reduced anti-
Quick-fried region area, to reduce the construction investment of safety devices.
The utility model is realized by following technical proposal: the positive draft type explosion-proof door socket in Yi Zhongjia, Class B workshop,
Including the explosion-proof door socket being arranged between general area and anti-explosion area, the several air outlets being arranged in general area and anti-explosion area, with
The pressure fan that air outlet is connected by pipeline, and the fire resisting damper being arranged on pipeline.
The general area and anti-explosion area are to divide first, Class B workshop, are divided into anti-explosion area and general area, and use is compound
Draft type；It is divulged information using direct current anti-explosion area；General area uses circulating ventilation.
The blower setting is in Air Conditioning Facilities.
The general area is connected by being provided with the pipeline of return air inlet with pressure fan.
It is equipped with several exhaust outlets in the anti-explosion area, and passes through the air draft to outside anti-explosion area of pipeline and explosion-proof exhaust blower.
Check-valves is additionally provided in the pressure fan and the connecting pipe of explosion-proof door socket.
The fire resisting damper is 70 DEG C of normally opened fire resisting dampers, is regular market purchase product.
The explosion-proof door socket, which is positive, presses the explosion-proof door socket of aeration type.
Fire resisting damper is additionally provided in the connecting pipe of the return air inlet and pressure fan.
Fire resisting damper is additionally provided in the connecting pipe of the exhaust outlet and explosion-proof exhaust blower.
The utility model has the beneficial effects that setting positive draft type explosion-proof door socket, to explosion-proof door socket inside be continuously fed to do
Net fresh air makes explosion-proof door socket inner space keep opposite positive pressure, by gas differential pressure control principle to space into
Promoting the circulation of qi is isolated, and isolation explosion-proof area danger medium diffusion is isolated danger (inflammable and explosive) gas, is effectively prevent explosion-proof
Region hazardous gas Medium Diffusion effectively reduces the explosion-proof area area in first, second workshop, subtracts to non-explosion-proof (common) region
Small explosion venting air-conditioning system scale, in the investment and operation energy for guaranteeing to reduce ventilation and air conditioning system under the premise of safety in production
Consumption, to reduce safety devices investment.Investment and the operation energy consumption of ventilation and air conditioning are reduced under the premise of guarantee safety in production,
Realize energy-saving effect.This Technological Economy is practical, meets the requirement that country advocates economizing type development.What the utility model had
Feature: safety, economic, energy conservation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model positive draft type explosion-proof door socket；
Fig. 2 is certain composite ventilated structural schematic diagram of Class A workshop using the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
As shown, positive draft type explosion-proof door socket in first, Class B workshop include setting general area and anti-explosion area it
Between explosion-proof door socket, the several air outlets 4 being arranged in general area and anti-explosion area, the air-supply that is connect with air outlet 4 by pipeline
Machine 1, and the fire resisting damper 2 being arranged on pipeline.
The general area and anti-explosion area are to divide first, Class B workshop, are divided into anti-explosion area and general area, and use is compound
Draft type；It is divulged information using direct current anti-explosion area；General area uses circulating ventilation.
The pressure fan 1 is arranged in Air Conditioning Facilities.
The general area is connected by being provided with the pipeline of return air inlet 3 with pressure fan 1.Several rows are equipped in the anti-explosion area
Air port 6, and pass through the air draft to outside anti-explosion area of pipeline and explosion-proof exhaust blower 7.In the pressure fan 1 and the connecting pipe of explosion-proof door socket
It is additionally provided with check-valves 5.Fire resisting damper 2 is additionally provided in the return air inlet 3 and the connecting pipe of pressure fan 1.The exhaust outlet 6 and explosion-proof
