Description
Technical Field
The utility model relates to the field of factory building equipment, in particular to a micro-negative pressure ventilation device for a closed factory building.
Background
Some chemical production workshops need to possess good ventilation conditions when keeping the factory building airtight, current negative pressure fan system wind-force is big, pressure is low, and in big factory building, can't reach the effect of point-to-point, ventilation effect is not good, for solving this problem, traditional method is for a plurality of negative pressure fans series connection, causes the waste of resource, and efficiency is lower, and current ventilation system still has the noise big, has environmental pollution's problem, and negative pressure system can't add any heating function, and when indoor outer difference in temperature was great, the long-term opening in winter can cause indoor temperature's obvious decline, influences indoor travelling comfort.
Disclosure of Invention
The utility model aims to solve the defects of the prior art, and provides a micro-negative pressure air changing device of a closed plant, which comprises a negative pressure system and a positive pressure system.
Further, the number of the vertical air supply pipes is two.
Further, the vertical air supply pipes are arranged on two sides of the square air supply pipe.
Further, the number of the first exhaust outlets is 8.
Still further, the first fan is mounted with an exhaust filter.
Compared with the traditional factory building micro negative pressure ventilation device, the utility model has the following advantages:
(1) the factory building is seal structure, installs exhaust gas filter at negative pressure system's fan end, reduces environmental pollution.
(2) The fan position can be adjusted to the upper side of the factory building, but not the side, so that noise pollution is reduced.
(3) The positive pressure system is provided with the temperature control unit, so that the indoor comfort level can be maintained while the negative pressure of the factory building is maintained.
