the utility model provides an environment collection cigarette pressure equaliser, is become by advancing tobacco pipe way, constant speed box, reducing pipe and constitutes, advances tobacco pipe way one end and constant speed box one end fixed connection, the constant speed box other end and reducing pipe one end fixed connection, the opening and the desulfurizing tower entry expansion joint fixed connection of the reducing pipe other end.

The smoke inlet pipeline consists of 4 smoke inlet pipes with different inner diameters, and the central lines of the smoke inlet pipes are positioned in the same plane.

The constant-speed box body is composed of a constant-speed pipe and a partition plate, the constant-speed pipe is located on one side of the constant-speed box body, the partition plate is fixed on the other side of the constant-speed box body, one side of the constant-speed pipe is fixedly connected with the reducer pipe, the other side of the constant-speed box body is divided into four parts by the partition plate, and each part is fixedly connected with the smoke inlet pipeline.

And reinforcing ribs are arranged outside the constant-speed box body.

The constant-speed box body is made of carbon steel or stainless steel.

The utility model has the advantages that: the investment and the operation cost are saved, the process of inputting four flues of the company into the annular set desulfurizing tower is taken as an example for comparison: the existing valve and computer control system can be adopted, the constant speed box body technology of the utility model can also be adopted, the investment of the required fixed assets is about 60 ten thousand yuan by adopting the existing valve and computer control system, and the investment of the constant speed box body of the utility model is only 30 ten thousand yuan; and the working costs is low, adopts current valve and computer control system, and clearance, management and electric power expense need about 15 ten thousand yuan at least every year, and adopt the utility model discloses constant speed box technique, annual working costs is 5 ten thousand yuan at most, the clearance of mainly used inside once a year, simple and convenient practical high efficiency.
